The missing link in whale evolution

One large whale (the unique sperm whale) has teeth, and all the smaller whales and dolphins do. The rest, the mysticetes, ranging from medium-size to titanic, use baleen to strain out fish or crustaceans. When did the split from the early toothed ancestors occur? Now we know. This whale, 28 million years old, has a sieve made out of teeth, a huge and heretofore undocumented change in the cetacean lifestyle.  To my fellow Christians who think the world is young and the fossil record lacks transitional specimens, I would say you can't ask for a better transitional fossil than this one.

Book Review; When Fish Got Feet

When Fish Got Feet, Sharks Got Teeth, and Bugs Began to Swarm: A Cartoon Prehistory of Life Long Before Dinosaurs 
Paperback –  2009
by Hannah Bonner

Amazon data:
  • Age Range: 10 and up 
  • Grade Level: 5 and up
  • Paperback: 48 pages
  • Publisher: National Geographic Children's Books; Reprint edition (September 8, 2009)

This book offers a unique and delightful look at the Silurian and Devonian periods, suitable for school children but including some funny bits and cool facts that will help adults learn or recall the main events of this pivotal time in our planet's history.  It also is the only book I've seen for kids that provides some information on my favorite predator, Dunkleosteus, incidentally playing it conservative and assigning a length of 6m where some books say 8 and a few old ones say 10.  There are short, clear explanations of everything from the creation of soil to the adaptations needed for plants and animals to invade the dry land environment.  Recommended to my by no less than Matt Mossbrucker and Dr. Robert Bakker, this is just a terrific book: order one for your kid's library and another for yourself.

New mammal from Alaska

New mammal species in North America are very rare - years can go by without finding a new rodent (they pretty much all are rodents these days.)  However, here's something a bit more spectacular - a new flying squirrel. Humboldt's flying squirrel is a bit smaller and darker than the close relative is used to be mistaken for.
Discovery never ends...

Looking Back: Little Living Fossils

              
Everyone is fascinated by the idea of "living fossils," which isn’t a precise scientific term but is a popular way to refer to animals which have survived unchanged while the evolving world passed them by.  I looked at a lot of these in Rumors of Existence, my first book, and they still interest me.
The coelacanth is the most famous: others include the tuatara, a lizardlike New Zealand reptile whose three eyes (the third is degenerate but functional) watched the dinosaurs come and go.
The term "living fossil" is not reserved for vertebrates.  Among the myriad specimens dredged up by the famous Galathea expedition in the early 1950s were ten limpet-like shelled animals.  They came from sea-bottom mud over 3,000, t beneath the surface off the Pacific coast of Costa Rica.    What were they?  No one was sure.  The new discoveries had pale yellow shells with an oval shape, about four cm long and one cm  high.  A large foot (colored pink and blue) was surrounded by five pairs of primitive gills.
                While the shell and teeth said "mollusc," the gill regions showed a segmented construction resembling annelid worms.  Was the new animal either of these, or was it something entirely unique?  It most resembled a model that biologist Brooks Knight had created showing what the ancestor of today's molluscs might have looked like.  But that hypothetical animal - no actual fossil had ever been found -  was presumed to have died out 350 million years ago.  Neopilina  galathea filled an important gap in the evolutionary record.  Taxonomically, the little critter was literally placed in a class by itself.  Since then, more Neopilina species have been dredged from the depths.  The scientific detective work of finding more examples and determining their exact place in the parade of evolution goes on.



Neopilina (Harvard)

                The great pioneering undersea vessel, the submersible Alvin (still working today!) pulled in one of its many notable discoveries in 1979.  Near a hydrothermal vent in the eastern Pacific, researchers on the sub collected a strange-looking stalked barnacle, the stalk serving to allow these normally fixed creatures some degree of mobility.  It had never been seen before, even as a fossil, but apparently belonged to a group which flourished before the dawn of the Age of Reptiles.
                The waters off New Zealand produced a similar surprise in 1985.  Clinging to sunken logs a thousand meters below the surface was a round animal barely over a centimeter wide.  Named the sea daisy, it appeared to be a distant relative of the starfish, even though only vestiges of the classic five-pointed starfish design were apparent.  That was enough to put it into same phylum, the echinoderms, but it proved very difficult to classify this diminutive invertebrate more precisely. The sea daisy is spiny on top, and its underside is covered by a flat membrane that biologist Michael Bright compares to plastic wrap stretched over an upside-down saucer.  The sea daisy, too, was assigned its own class (now the infraclass Concenticloidea, in which it inhabits the order Peripodida. Two other speies have been added).  When it was discovered there was just nothing like it, except for fossils predating the dinosaurs.  
                Fossils from the same period included the graptolites, tiny colonial creatures who built homes of collagen secretions layered in strips like mummy bandages.  At one end of each 2.5cm-long long communal house, a peculiar sharp spike rose like a TV antenna.  Graptolites were presumed to be related to modern homebuilders called pterobranches, but pterobranch dwellings lacked the characteristic spike.
                After an apparent absence of 300 million years, graptolites resurfaced.  In 1992, French researchers sent a sampling of seafloor specimens to Dr. Noel Dilly, a London ophthalmologist whose "hobby" of studying pterobranches grew on him until he became one of the leading experts on the animals.  Dilly's first reaction was, "Not another boring collection to hack through."  His second was, "I don't believe this."  He was looking at characteristic graptolite dwellings, spikes and all.
                The graptolite is a reminder that not all animals evolve: some just find a comfortable ecological niche and settle down for a long stay.
                There an awful lot of little creatures like this to be found.  In the mid-1980s, Frederick Grassle of Rutgers University led an effort to collect over two hundred core samples of the Atlantic seafloor.  When all the sediment had been sifted, the somewhat flabbergasted scientists found they had collected 460 new invertebrates. 
                 The littlest animals offer many surprises, and no one thinks the surprises are over.

We can't ignore climate change - or our role

The President, as Presidents can do, withdrew from an executive agreement signed by his predecessor.  OK, that's legal. It does not make it wise.
In the Industrial Age, we have poured 600 billion tons of carbon products and compounds into the atmosphere.  Now, the atmosphere weighs about 5.5 quadrillion tons, so it's not like we've replaced the whole shebang, but chemical reactions are tricky things.  Just as you cannot ignore 25 µg of LSD in your 80kg body (it will probably kill you), you can't ignore 400 ppm of carbon compounds.  We haven't had that much in hundreds of years, and climate scientists are almost universal in their agreement this is enough to be really, really scary.  It's not that 400 is a magic number that tips us into a pit of no return.  But as one JPL expert. Dr. Michael Gunson, puts it, "Passing the 400 mark reminds me that we are on an inexorable march to 450 ppm and much higher levels. These were the targets for 'stabilization' suggested not too long ago. The world is quickening the rate of accumulation of CO2, and has shown no signs of slowing this down. It should be a psychological tripwire for everyone." As another NASA expert, Dr. David Crisp, says,  (400ppm) "brings home the fact that fossil fuel combustion, land use practices, and human activities have increased the CO2 concentration in Earth’s atmosphere by more the 20 percent since I was born."
It's not a conspiracy.  There has never, in human history, been a situation where 95 percent (or so) of scientists in a given field were all in on a conspiracy.  A large majority of scientists can be wrong (see: continental drift), and the self-correction mechanisms of science work a lot slower and clunkier than we would like, but we're talking about decades of near-consensus despite bringing online more and more accurate tools and measurements without budging the needle one bit on the "consensus-o-meter." We're talking about research that's gone on long enough that a new generation of climate scientists has come in since the early alarms were sounded, eager to find new things, and what they found was the same thing - only worse.
We have to act.  Yes, some of the hand-waving about the magic of renewables is wishful thinking: we cannot change the global economy easily or painlessly.  Any time you see a headline like "Germany Ran On 100 percent Renewables Today" it's always a result of cherry-picked data. The task ahead of us is orders of magnitude harder than putting up more windmills.  But we still have to address it.  

One GOP Congressman said God will fix it. Le'ts talk about God for a minute. I believe in God, although I don't read the Old Testament literally.   God did do something: he gave us the brains to solve our problems if we muster the will.  
Let's take Exodus. Whether you think the flight through the Red Sea is literally true or is a story written to emphasize God's love for His people, the lesson is that same.  If Moses was going to get everyone across that sea before it closed in on the Egyptians, he had the sense to hurry, to leave behind possessions, to help the old and slow keep up, and otherwise to get organized really fast under pressure and execute the plan he needed to execute. If God wields the power He displays in parting the sea, it must also be true that He could have reached down, made the escape route permanent, and crushed the Egyptian army so Moses could take his time. But God doesn't do that: He creates just enough of an opportunity that Moses and company could take advantage of it if they did all they could for themselves.  They did, and we can do no less. A common Christian precept is "God has no hands but ours." We are entrusted with the stewardship over the planet and our fellow creatures, and no one is going to save them if we don't. 

The President is not entirely wrong when he says the U.S. is called on to do more sacrificing than most nations. We are. But that's because we have the means.  Just as the U.S. needed to take a leading role against the Axis in WWII, because we had the industrial might to do more than the outnumbered British or the conquered French, we have to take a leading role against this enemy.  In some ways, it's not fair.  But the facts on the ground don't change.  Those who can do the most have to do the most.  The President doesn't like the idea of the U.S. surrendering some sovereignty, but we are really not: as the accords are not binding, we can choose how much to contribute or how much to change. The other nations can't force us to, say, contribute $200 billion over the next whatever vs. $100 bliion (or $300 billion).   We can and msut take a leadership role, but we decide the details of that role.

Let's forge on.

Microsatellites: Tom and Jerry

To image distant stars and planets with increasingly greater precision, you need a baseline array of two or more satellites looking from slightly different angles (a massive oversimplification, but stay with me here, I admit to not being a space engineer).  The point is that it's very difficult to get satellites into the right formation and hold it without impractical quantities of fuel.  A US/South Korean project is testing it with two CubeSats, one 2u (two unit, 20cm x 10cm x 10 cm), and a 1U (10x10x10 cm) for less than $1M.  Aviation Weeks's overview (may require free registration)  is here, and the launch provider (India) posts its manifest here. NASA's article is here. It's amazing stuff for a tiny spacecraft costing less than a lot of U.S. houses!

Whales Got Very Big, Very Fast

Fast in evolutionary terms, anyway. Today's filter-feeding giants appear only 2-3 million years ago in the fossil record.  Why? According to these scientists, it was pretty simple: unlimited food.  With predators, mainly orcas, getting 8-9 m long and hunting in packs, size provided protection, but getting big is a defense that can only work if there is no shortage of food. As the lush plants of the Mesozoic let plant-eating dinosaurs grow to 30m and more in length, having a "license to krill" (I love that pun, although I did not invent it), let blue whales push the 100 metric ton mark.

Fun fiction: Full Wolf Moon by Lincoln Child

FULL WOLF MOON
Lincoln Child
Doubleday, 256pp


  This outing for "enigmaologist" Logan offers a lot of fun for his growing number of fans. While it has slow spots and not every twist is a surprise, readers will learn more about Logan in the course of his effort to relax and write a monograph on history at a retreat that is a little too close to some strange, savage murders. Investigating at the behest of a new and interesting character, a philosopher-forest ranger he knew at college, Logan finds a hidden laboratory run by a mad scientist (as in, not so much crazy as literally MAD at everyone) and a local belief in lycanthropy. This sounds cliched, but the Logan novels are out to put a new spin on classic horror tales, and Child keeps it fresh. The atmosphere is wonderfully real and creepy. There is some interesting real science, some way-out invented science, a little bit of the paranormal, and some nods to the old Hammer Films universe as Logan risks his life to figure out who or what is haunting the remote Appalachian forest. As a science writer and a novelist, I appreciate the way Child can meld the real (gene therapy), the speculative (what if full moon effects are not mythical after all, we've just not studied them right?), and the horrific.

A mind-blowing dinosaur fossil

Fossil news seems to come in too fast to keep track of these days, but this chance discovery pretty much froze paleontologists in their trackways.
One of the best fossils ever
A Canadian fossil of a nodosaur (think the iconic Ankylosaurus with no club tail but some big shoulder spikes) was buried in a shallow sea in fine sediments under conditions that offered extraordinary preservation. Scientists can see where the horn spike ended and the keratin sheath began and extended from it. They can count the scales on its body.  "It looks like a sculpture" seems to be a common comment. Five years of painstaking work, totaling some 7,000 man-hours (not unheard-of in paleontology!)  were needed to free up, clean, and reassemble the front half of the animal. That's all we have, but scientists are happy to take it. The skin is there. Even traces of its coloration remain. It's a marvel.

Review: Hunting Monsters by Dr. Darren Naish

Hunting Monsters: Cryptozoology and the Reality Behind the Myths 

by Darren Naish

(paperback edition, 2017, Sirius)


As a cryptozoological reader of some 40 years and writer of 20+, and a correspondent of Dr. Naish, I looked forward to this book, and I'm hardly disappointed. Naish offers a very good skeptical analysis of the whole cryptozoology business, even if I think it could have been a little better. 
One point a reader will notice early on is that there is so much ground to cover that the author can only touch on many points in passing. Skipping over the Great New England Sea Serpent, a touchstone of the sea monster topic, is an example. 
Naish starts with whether cryptozoology is, or can be, scientific, and agrees it can be but isn't often. He begins and ends with the point cryptozoology exists in a cultural milieu and is influenced by folklore, tradition, etc. as well as modern innovations like the Internet. This isn't entirely original and he credits influences including Dr. Charles Paxton, whose work I greatly admire, and folklorist Michel Meurger, who I've always thought overreached the subject.
Naish is not closed-minded about this. He has himself put forward new species concepts over the years to explain cryptozoological sightings, including a cryptid seal and a giant orangutan, but in his blog Tetrapod Zoology and elsewhere he's uncovered or been offered new information and has generally come to conclude the "star" animals are not physically there. This book explains his reasoning well.
When he offers an explanation, I'm not always entirely convinced: the "finning" seal (a seal waving one flipper in the air for cooling) for the Valhalla sighting, for example, is clever, but I can't look at the first-hand original drawing and get a seal out of it. (As you can tell, I enjoy sea serpent lore more than the rest of the subject these days.) The opposite is true of the HMS Daedalus sighting, which I think we can put to rest.
The subject is vast and Naish can't help that, so the bibliography is essential: it's pretty good but could have been more extensive.




Lest anyone think I'm damning with faint praise, this is an excellent and important book. If it doesn't hunt down every major cryptid, it will make the veteran cryptozoology reader think hard and will give the new reader an excellent starting point grounded in good science.

A golden sturgeon?

The white sturgeon of the Fraser River is an impressive creature, known to reach over 3 meters and approach 400kg,and claimed to reach 6 meters.  It comes in definite or reported shades of green, brown, or black (never white - go figure).  But a gold sturgeon? It exists, and this video proves it. Fortunately, the two fishermen who caught it did the right thing and released it to continue to grow and, perhaps, enchant people in the future.  

Sometimes it's ok to just look at nature and say, "wow." 




"Normal" white sturgeon (Wikimedia Commons - photo by Joseph Tomerelli)

Don't forget the role of the giant sturgeon in myth and legend, captured by Longfellow in this case of an improbably big and improbably colorful sturgeon (purple fins?)

Forth upon the Gitche Gumee,
On the shining Big-Sea-Water,
With his fishing-line of cedar,
Of the twisted bark of cedar,
Forth to catch the sturgeon Nahma,
Mishe-Nahma, King of Fishes,
In his birch canoe exulting
All alone went Hiawatha.
  Through the clear, transparent water
He could see the fishes swimming
Far down in the depths below him;
 
  On the white sand of the bottom
Lay the monster Mishe-Nahma,
Lay the sturgeon, King of Fishes;
Through his gills he breathed the water,
With his fins he fanned and winnowed,
With his tail he swept the sand-floor.
  There he lay in all his armor;
On each side a shield to guard him,
Plates of bone upon his forehead,
Down his sides and back and shoulders
Plates of bone with spines projecting!
Painted was he with his war-paints,
Stripes of yellow, red, and azure,
Spots of brown and spots of sable;
And he lay there on the bottom,
Fanning with his fins of purple,
As above him Hiawatha
In his birch canoe came sailing,
With his fishing-line of cedar.
  "Take my bait," cried Hiawatha,
Down into the depths beneath him,
"Take my bait, O Sturgeon, Nahma!
Come up from below the water,
Let us see which is the stronger!"

  From the white sand of the bottom
Up he rose with angry gesture,
Quivering in each nerve and fibre,
Clashing all his plates of armor,
Gleaming bright with all his war-paint;
In his wrath he darted upward,
Flashing leaped into the sunshine,
Opened his great jaws, and swallowed
Both canoe and Hiawatha.

Death by sea serpent?

Death by Sea Serpent?
In the modern (post-WWII) history of “sea serpent” reports and claims - and there are still reports, albeit rarely - we have only one claim of human fatalities. This story appeared in the May 1965 issue of Fate Magazine and still kicks around in the Internet.
In a first-person account, Edward Brian McCleary claimed to have had a terrifying experience on March 24, 1962 off Pensacola, Florida. McCleary and four friends paddled a life raft out to dive on a wrecked ship. A sudden storm came up, forcing them away from land. At night, a fog closed in on them. In the fog, they hear something moving, and then saw what looked momentarily like a “like a telephone pole about ten feet high with a bulb on top” in the fog. The object was, however, a plesiosaur-like animal. More specifically, “The neck was about 12 feet long, brownish-green and smooth looking. The head was like that of a sea-turtle, except more elongated with teeth. There appeared to be what looked like a dorsal fin when it dove under for the last time. Also, as best I am able to recall, the eyes were green with oval pupils.”
This creature proceeded to kill McCleary’s companions one by one. McCleary alone managed to make it to a protruding mast of the wreck they were diving (the U.S.S. Massachusetts), where he clung until daylight.
The Massachusetts sits today in only 26 feet of water in the Fort Pickens State Aquatic Preserve, with portions of the ship still protruding from the sea. McCleary still lives in Florida, though he apparently has not spoken on the subject of the attack since his article came out. The deaths are real, too, and McCleary did report them, but the Coast Guard found nothing more than a tragic episode of accidental drowning.
What are we to make of this? It's very hard to take seriously even if, as some researchers (myself included) believe, there might still be a huge eel or other creature behind some sea serpent stories, The plesiosaur-like creature striking its victims from the fog sounds like a scene from a bad horror movie. The very plesiosaur-like sketch McCleary made of his creature shows the head joined to the neck at an odd 90-degree angle, and McCleary does not explain by what light he saw enough to describe his creature.

So I'm afraid we have to write this tale off.  The sea serpent is the most romantic (in the Victorian sense) of legendary creatures, and no one wants to let go of it, but no one can catch hold of it, either.  Fortunately, the animals the DO inhabit the oceans are spectacular and curious enough for anyone..

Echoes from the Ivory-bill

I've never been quite convinced the ivory-billed woodpecker (Campephilus principalis) is extinct.  
It may be wishful thinking, or it may be that a story I heard 20 years ago lingers in my mind.  I was in the Denver Museum of Nature and Science talking to a woman sculpting an elk.  The story she told me is that years after the last supposed confirmation of the ivory-bill (1950, Florida) she'd been a girl of about 10 hiking in the Singer Tract in Louisiana. Her father put a finger to his lips to shush her and pointed to a magnificent red, white, and black bird on a stump in front of them. The witness, Ruth Laws (or Lowes: I didn't write down the spelling and haven't been able to locate her) said her father whispered, "That is an ivory-billed woodpecker. Take a good look, because you'll never see one again." She never did.
This bird may be extinct. It may very well be functionally extinct - that is, there are some individuals, but not enough to continue the species.  People like Michael Collins of the Naval Research Laboratory spend years of their lives searching for the birds.
Collins thinks he's found them
His videos, according to other experts, are not definitive: the birds in them could be ivory-bills, but they are too far from the camera to tell, so they might also be pileated woodpeckers, although the behavior certainly fits.
There are good reasons we all want the bird to be found. The nickname "Lord God bird" was applied based on the exclamations of countless witnesses. One admiring  expert, ornithologist Dr. Lester Short, wrote that, "If the woodpecker world had royalty, the ivory⌐bill would be king."
The bird had a specialized diet, based on beetles living in dying or recently dead trees in Southern forests. When these forests were cleared, the birds had a difficult - maybe impossible - task in adapting to secondary growth. 
Still, reports lingered - in Florida, in Arkansas, and in other states. Ornithologist John V. Dennis had a good sighting in East Texas in 1966.  Dr. Jerome Jackson got responses to recordings of ivory-bills in 1987 and 1988.  In Cuba, a bird was conclusively identified in 1986, although an extensive search in 1993 found nothing, and that seems to have been the last of the Cuban birds (sometimes considered a separate subspecies).  (Or was it? Ornithologist Tim Gallagher led an expedition to the island in 2016, although proof remained elusive.) 
In April 1999, David Kulivan, a graduate student in wildlife biology, spotted a pair in Louisiana's Pearl River Wildlife Management Area. The sighting was convincing enough to result in a major search, without luck. The Louisiana  Ornithological Society put out an ivory-bill T-shirt captioned, "I Want To Believe," a mantra from the The X-Files.In 2004, a sighting and video from Arkansas led to the official announcement of the bird's rediscovery by U.S. government authorities. (The result, published in the leading journal Science, might be the most famous paper ever published about birds.) The identity of the bird in the video has since been questioned, though and the species, once again, seems to have disappeared.   
And so it goes - scattered reports, calls, distant images and videos. The ivory-bill has become the sasquatch of the bird world - widely sought, wiedely believed in, but not quite there in evidence the scientific world can widely accept.
I think it's still there.
Because I want to.

U.S. Science Funding: FY17 does well

Sources including SCIENCE magazine have parsed the funding in the new continuing resolution covering FY17, and it's not terrible - in most ways.

The big cuts feared by science advocates are not in this bill.   NASA does more than ok with $19.653 billion for the whole fiscal year. Indeed, NASA does a lot better overall than was projected by the last Obama budget, with the biggest increase coming in the Exploration account, which includes human exploration, a favorite of the new  President. Planetary science went up, and Earth science, a likely future target, gets the same amount as in FY16.

Basic and applied research goes up, and both military and civilian agencies benefit. The EPA's research budget took a major hit, though, and the Department of Energy's fusion-power research was hammered, which has international implications given the consortium on the ITER experiment would have to push out their deadlines (at best) without U.S funding.  (Also, my personal opinion is that anything that moves us closer to fusion power needs a MAJOR increase, not a cut.)   The Congress controlled by the President's party poked him in the eye, sharply, with a $2 billion increase for NIH.  

President Trump's FY18 budget is another matter: it's the one that slashes much more funding for the EPA and biomedical research, among other things.

So the major battles lie ahead...

Thanks to the Pikes Peak Writers Conference

A great 2017 conference!

A few takeaways from the Pikes Peak Writers Conference, shared for fellow authors:
Agent Sam Morgan agreed with a quote from Dean Koontz I mentioned (that you can have one big improbability in your story if you nail down all other details in reality) and added that, for any kind of thriller,"You get one coincidence. Just one."
Agent Donald Maass emphasized that in any interaction between people, there are always multiple levels of emotions at work, never just one emotion.
Maass also took issue with the pessimistic view of the long odds against getting published because you can change the odds. How many books you write,how many agents you query, how hard to work at your craft, etc. - it's not like a casino where a thousand to one guarantees you lose.
Author Jennie Marts emphasized the need to use every tool available on your Amazon author page and your individual book pages to make you look good, to tell your story, and to promote your other books.
Also Jennie Marts: You begin to define your "brand" with the first work you publish in any form. Keep the big picture of what kind of author you want to be in mind with everything you do. The "brand" you project is a promise to your readers about what they will get if they buy your books.
From multiple sources: While you should try to make your query letter and proposal perfect, one error won't kill you. One agent scratched out two whole paragraphs of my one-page query letter but asked to see sample chapters.
Multiple sources: In adult fiction, a white guy like myself can write characters from many cultures if you avoid stereotyping, but most publishers are not open to someone like me writing middle grade or Young Adult fiction including foreign or minority cultures. (Comment: I understand the concern, but it seems to me that that may be TOO sensitive: researching a book is one of the best ways to learn about another culture and introduce it to readers. See: Dana Stabenow.)
 From author Laura DiSilverio: we under-use setting in defining characters. People decorate, not only houses, but cars, cubicles, etc. with things that can help readers understand them. Another good way to expose character is taking people out of their chosen or normal environment: how do they react?
Consensus of agents and editors: avoid prologues unless they are really good and can't just be part of Chapter One: it's usually best to avoid them even then. (Comment: William Kent Krueger is a brilliant user of prologues.)



Myself, at the costume-optional Friday night dinner, as wizard Harry Dresden, with agent Donald Maas (agent for Harry's creator, Jim Butcher, to whom he sent this pic).



Author Travis Heerman: Stephen King (not present :) ) says all first drafts can be cut 10 percent. Also, revision should genuinely be "re-visioning," not just line editing. Use beta readers, reading aloud, text-to-speech, or any other tool to ensure you look at it it in different ways. This takes time and you MUST be willing to commit to it for a good book.
Editor panel: Publishers grind everything through a profit-and-loss equation at some stage, but you can't control that: control what you can (writing a good book). Also, for fiction, a good enough book can make the cut even if the author doesn't have a major social media presence and followers: for nonfiction, it's much more important.
Thanks again for a great conference. #PPWC2017


See you all at 2018 Conference. One guest already confirmed: favorite author (okay, co-favorite with Dana Stabenow) Jim Butcher.

And a new shark just swam in..

OK, that's not exactly accurate. It was discovered by DNA sampling of hammerhead sharks off Belize.  But there have been at least a hundred new sharks discovered since I've been following this for the last 25 years or so, and the number known is zooming toward 450. Some are found by DNA study, some identified in the field or from catches by fisherfolk. Finder Demian Chaplin notes, "...finding of a new species in Belize highlights that there could be more undescribed ones out there, each one facing a unique set of threats.”  Shark conservation is a global problem: predators are vital to healthy ecosystems, and we're not conserving very well.

Prehistoric Times revisits a great paleoartist

The new issue of Prehistoric Times (#120, Winter 2017) has a great article on the paleo-artistry of Zdenek Burian, including reproductions of two paintings containing Dunkleosteus terrelli (then Dinichthys) from 1955 and 1967.
I'm not reproducing them here for copyright reasons, but while he worked assiduously with paleontologists to make his illustrations (which appeared most famously in Dr. Josef Augusta's very influential Prehistoric Animals (1956), where Burian got co-credit on the cover), his Dunk is a little odd to me. It's the most smooth and streamlined Dunk I've ever seen, tapering perfectly like a nuclear submarine to an elongated teardrop.
That muscle and skin made the armor almost invisible is certainly possible, but the eel-like tail isn't very substantive, and I am certain the pectoral fins are too small: they needed to precisely control a ton of head/armor stretching several feet ahead of them. All that said, the illustrations are wonderful, bringing to life the great predator, its relatives, and its surroundings: I'm looking for a copy of Prehistoric Animals right now.

Interview: Liz Ruth, pilot of NASA's SOFIA

SOFIA - NASA's Stratospheric Observatory for Infrared Astronomy - is a unique and rather amazing resource for science.  Operated for NASA by the Universities Space Research Association (USRA), it's been flying since 2010. It carries a 2.5m infrared telescope exposed by opening an access door in the portside rear fuselage.  In January 2017, NASA published the first image from an upgraded instrument, the  High-resolution Airborne Wideband Camera-plus (HAWC+).

My college friend, Elizabeth Ruth, is one of the pilots for SOFIA.    Since she's she also a very smart and inquisitive person, I thought she also would be the right pilot to ask about how this singular instrument and its carrier aircraft are operated.  Take it away, Liz.









1.      You were an Air Force and airline pilot, then you didn’t fly for a few years. Can you briefly sketch your background and tell me what drew you back to pursue the SOFIA opportunity?

I was lucky enough to grow up on a Navy base in the middle of the Mojave Desert (pretty counter-intuitive though that sounds) during the 1960’s and 70’s. I was surrounded by scientists, engineers and pilots, the skies were full of airplanes, and sonic booms were a daily occurrence. I wanted to fly as long as I can remember, and the doors to that opportunity opened for me at just at the right time. I went to college on an Air Force ROTC scholarship and attended pilot training after graduation. I flew for two tours in the Air Force and then left active duty to become a pilot at United Airlines. My husband, who was also an Air Force pilot, started flying for Delta Airlines at about the same time. I flew for United for 16 years, then retired early to stay home full-time to raise my three daughters.

I knew that I would want to return to some kind of work once my girls went to college, but though I missed flying, I did not intend to return to the airlines. The seniority system they use meant I would have to start all over at the bottom, which I was not willing to do. I worked in a couple of office jobs and quickly learned that a Monday-Friday, 9-5 desk job was not inspiring to me at all. I felt I should be able to make a better contribution that took advantage of all my training and years of flying experience.

Serendipitously, I ran into a NASA pilot while I was traveling. We struck up a conversation and he told me about the positions at the Armstrong Center, including flying SOFIA. He said they were always looking for part-time pilots who have a military background and experience flying heavy airplanes. I knew instantly that this would be a dream job for me, and I met all the qualifications. Who wouldn’t want to work for NASA? He told me how to apply, we kept in contact, and a position came open. I had several interviews and a flight check ride and got the job. Once I was hired, I went through several months of training and now I am a type-rated 747 pilot checked out on SOFIA. So now I am back to where my dreams began—in the California desert, surrounded by scientists, engineers and pilots. I have had several cool jobs throughout my career, but this one is the absolute best.


2.      Had you flown the 747 before? Does it handle as nicely as most pilots I’ve read articles by say it does?

Yes it does! During my flying career in the Air Force and at United Airlines, I have flown most of the Boeing aircraft models—737, 757, 767 and 777. Though I always wanted to fly a 747, it just never worked into my schedule at United, so I am thrilled to get the opportunity now. SOFIA is a 747 SP. The SP officially stands for Special Performance but we call it the “Sport Model” . I would say that SOFIA flies like a big 737-200. It has plenty of power, no real quirks, and is very responsive. It is an extremely well designed airplane that has stood the test of time. I don’t know of any pilots who don’t love it.

3.      That telescope mount is pretty massive. How dies it affect the flying qualities of the aircraft, especially with the aperture open?

Believe it or not, we can’t even tell in the cockpit when the door is open or closed. We can’t even feel when it is in transit. This is another exceptionally well-designed piece of machinery.


4.      Can you describe for me the typical mission? How much science time do you get in, and how long is the entire effort, from arriving at the airport to departing?

It’s a very long night! The start time depends on what is being viewed that night, but typically we will take off shortly after sunset and land sometime before sunrise, with the actual flying time usually being somewhere between 9 – 10 hours. The preparation for the flight starts much earlier, of course.

Takeoff minus 3 hours: Crew Show and Briefing. The crew show time is 3 hours before takeoff time. We each individually review the flight plan and conditions for the night, then we conduct a formal flight crew briefing, which includes the pilot, copilot, flight engineer, flight safety technicians, flight operations engineer, mission planner, meteorologist and a representative for the mission director. We go over the status of the airplane, the flight plan specifics and the weather along the route. We make plans for contingencies such as aircraft or telescope malfunctions. The timing at each point is critical, so we also figure out if we can make any adjustments for a late takeoff. This will depend on the science priorities for the mission.

Takeoff minus 2 hours: Mission Briefing. The next step is the mission briefing, which includes the entire crew for the mission as well as the planners, engineers and meteorologists. We cover some of the same information for the scientists as we did in the aircrew brief, along with additional information that is crucial to them, such as the water vapor levels at each altitude. The scientists brief us on exactly what they are looking for with their instruments on each leg and which legs have priority if we have to make any adjustments for weather.

Takeoff minus 1 hour: Preflight and start. We all head out to the aircraft to preflight and prepare our respective equipment. The flight crew coordinates with the Mission Director every step along the way to make sure we are keeping on time. We close doors and start engines about 35 minutes before takeoff time to allow plenty of opportunity to troubleshoot any problems without delaying takeoff. We are usually the only airplane on the ground at Palmdale at that time of day, so there is typically no wait in getting a clearance for taxi.

Takeoff: We let the tower controllers know our “wheels up” time so they can coordinate with ATC for us to get up and out as per our flight plan. A precise takeoff time is critical to the success of the mission.

Climb out and level off: We work with ATC to climb without delay to our first altitude. This can be tricky if there is a lot of traffic around us, especially because we are not flying a normal kind of route, so we are crossing other airplanes’ paths. When we get straight and level, the mission crew runs the checklist with the flight engineer to open the door for the telescope. The first line of the flight is usually used to calibrate the equipment so they are ready for observations on the next line.

Inflight: Once the equipment is calibrated and working well, the scientists will start making their observations. If all the weather conditions are right (no clouds at altitude and no excessive turbulence) they can get 8-9 hours of observations in. At the end of the last line of observations, we flight straight and level for 5 minutes to cage the telescope, then the pilots can begin descent for the approach and landing.

Landing: After landing and taxi-in, the aircrew and mission crew depart the airplane and go to their respective offices to write reports. For the aircrew, these reports include filling out the electronic logbook for each of the crew members, talking to the mechanics and writing up any problems with the airplane, and writing a synopsis of overall success of the flight. This usually takes at least 30 minutes.

All told, the time from show to go is typically 13-14 hours.


5.      That’s not a new 747. How much effort does it take to keep it ready for these long missions?

We have a crew of aircraft mechanics and specialists at the Armstrong Center who take care of all the airplanes in the fleet, including SOFIA. They are exceptionally knowledgeable and are very good at creative problem solving, which is helpful when you are working with a one-of-a-kind aircraft. One of the most challenging aspects of maintenance is finding spare parts for such an old model of airplane. They know every source possible, including mothballed airplanes that can be “cannibalized” for parts. Our operations engineers make sure SOFIA is safe and mission ready while making decisions that are efficient and cost effective. It is a constant effort that they take great pride in.

6.      Do the pilots talk much with the scientists? Do scientists and technicians need to explain the telescope in detail to enable the flight crew to give them optimum conditions?

The pilots brief with the scientists before each flight and we are in constant communication with the Mission Director throughout the flight. We are very cognizant of the conditions the scientists need for the telescope to work best.  Mostly, we need to get as high as possible as soon as possible so we can get above as much of the water vapor in the atmosphere as we can for the most optimal infrared observations. There are constraints on the airplane, such as weight and air temperature considerations, that affect our ability to climb with a safe performance margin, and the pilots are constantly monitoring the conditions so we can climb as soon as it is safe. We are also on the lookout for any high-level clout tops, which would require closing the door to the telescope to protect it from moisture.

Turbulence doesn’t affect the telescope as much as you would think because of the way it is designed. The assembly is mounted on bearings in pressurized oil, so it stays pretty stable during the bumps. In rough air, it can look like the telescope assembly is bouncing, but it’s really the airplane bouncing around the telescope.

We have a carefully planned ground track, and we can’t deviate laterally without affecting the observations, so we work with ATC to make sure they don’t try to vector us off our heading. We are also constantly adjusting our airspeed and calibrating turns so that we stay within 2 minutes of the planned time at each point. We stay on headset with the Mission Director to coordinate all this with him or her.

7.      Do you (or do flight crews in general) usually have a lot of curiosity about the science and keep track of what’s being produced in terms of scientific results?

The flight crew’s job is to make sure we have the airplane safely at the right place at the right time so the scientists can accomplish their mission observations, so our main focus is on airplane operations. We all do a mission brief together with the scientists, so we know what the astronomers are looking at and looking for, but their level of knowledge is far beyond what we (or anyone below a PhD level in astronomy) can fully comprehend. They are good at giving us a high-level overview, but the specifics are pretty esoteric, like looking for one specific molecule in a gas cloud. I try to distill it down to a simple and concrete explanation so I can pass it on to ATC or other aircraft that hear our call sign (NASA747) on the radio and often ask, “What are you looking at tonight?”

Some of the observations will contribute to projects that have a very long timeline, so it will be years before we know the results. That said, one of the astronomers on a flight last month said he was able to get the information he needed to publish a paper in the next few months, which will be fun to see. NASA is good about notifying us when something concrete is published. It’s pretty satisfying knowing that you played a part in a scientific discovery.

8.      You started flying when it was very rare to see a woman in a military or airline cockpit. Are you the only woman flying SOFIA? Do you have an advice to young women about flying or science careers?

I am still a bit of an oddity in the cockpit, even after all these years. Right now, I am the only woman flying as a NASA Research Pilot at the Armstrong Center, out of about 30 total full-time and part time pilots who fly the various aircraft at the Center. This is actually close to the percentage of women flying professionally in the military and airlines at large, which has stayed around 4-5% over the last several decades.

It’s a mystery to me why more women are not attracted to the aviation field, or to STEM fields in general. One of the best things about being a pilot is that you are measured against an objective standard, which doesn’t depend on who you are, but rather what you can do. Pilots value and respect performance, and they will give you your due if you can perform. There is a real advantage to operating in an environment like that. The pilots, crews and scientists have made me feel very welcome at Armstrong. There are plenty of women scientists and Mission Directors, and we are all just part of the team.

My advice to young men and women is to follow what you love and find interesting. Dream and dream big—don’t put any limits on yourself. Someone is going to do the cool stuff, so why shouldn’t it be you? And then take the steps required to make that dream happen.

My favorite part of each mission is the Mission Brief, because I get to see the enthusiasm of the scientists describing their projects. It’s exciting and energizing! You will find that the top two attributes of a satisfying job are People and Purpose. This job gets an A+ on both. And for those creative types out there, just know that technical jobs require a great deal of creativity, imagination and beauty, so don’t cross them off your list.

 Last note from Liz:
If someone would like to talk to me more about my flying experiences, they can email me at Liz.Ruth@i3-corps.com.   I am always happy to talk to students or anyone else interested in the flying world. I live in the San Luis Obispo area in California, which is on the coast halfway between Los Angeles and San Francisco.

Thanks, old friend!
