"A poignant moment occurs near the end of the first episode of “Cosmos: A Spacetime Odyssey,” a rollicking 13-part tour of the universe to be broadcast on Fox starting on Sunday.
Sitting on a rock by the Pacific, Neil deGrasse Tyson, host of the show and director of the Hayden Planetarium in New York City, pulls out an old desk calendar that had belonged to Carl Sagan, the Cornell astronomer and author. On a date in 1975 he finds his own name. The most famous astronomer in the land had invited young Neil, then a high school student in the Bronx with a passion for astronomy, to spend a day in Ithaca.
Dr. Sagan kindly offered to put him up for the night if his bus didn’t come. As Dr. Tyson told the story, he already knew he wanted to be an astronomer, but that day, he said, “I learned from Carl the kind of person I wanted to be.” …
After a series of special showings this week, including one at the White House, it will be shown in 170 countries and 45 languages, on Fox and on the National Geographic Channel — the largest global opening ever for a television series, according to Ann Druyan, Dr. Sagan’s widow and his collaborator on the original “Cosmos,” who is an executive producer and a writer and director of the new series.
I’m not going to pretend to be neutral here. I hope it succeeds and that everyone watches it, not just because I have known Ms. Druyan and admired Dr. Tyson for years, but because we all need a unifying dose of curiosity and wonder. …
We could use a national conversation that is not about scandal or sports.”
"Much of the first episode consists of a tour of the solar system and then outward as Dr. Tyson fills out what he calls our long address:
Milky Way galaxy.
And we get to hop along a cosmic calendar in which the 13.8-billion-year history of the universe has been compressed to 365 days and it’s now midnight on New Year’s Eve.
On this scale, Dr. Tyson reports, the sun was born on Aug. 31, and the dinosaurs died yesterday morning in that asteroid blast. Everybody you ever heard of, all the kings and queens and prophets, lived in the last 14 seconds of this cosmic year. ‘Jesus was born five seconds ago,’ he goes on.
'In the last second we began to do science,' he concludes. 'It allowed us to discover where and when we are in the cosmos.'
This is going to be fun.”
The Morphology of Human Blood Cells (1956)
Dorothy Sturm’s beautiful watercolors are difficult to distinguish from an actual microphotograph (except perhapsthey are clearer and more detailed than a micrograph, and certainly superior to images from the 1950’s). Sturm’s watercolor on paper illustrations, drawn directly from Wright-stained smears prepared by [microbiologists], depicted normal, pathological and infectious hematology with a clarity, detail and beauty that photomicrography of the 1950’s simply couldn’t approach. JAMA, in a review of the first edition, even called her work “of exceptional quality.”
 This table showing hematopoiesis (as it was understood in 1956) was the frontispiece of the first edition of Diggs’ The Morphology of Human Blood Cells. Here’s the key to this illustration.

daniel stoupin, a doctoral candidate in marine biology at the university of queensland, has photographed a variety of coral species using full spectrum light to reveal fluorescent pigments that would otherwise be invisible to the naked eye. each piece (click pic for name) is from the great barrier reef. given the complexity of the techniques used, which involve time-lapse and stereoscopic and focus stacked photography, the images take up to ten hours to produce in the lab.
Wow. I thought these were computer-generated protein models or something at first, but these are brilliantly fluorescing corals!!
What might be seeing these stunning fluorescent displays? Coral aren’t known to have any photo-sensitivity (at least past the larval stage), so the obvious candidates are fish, whose eyes would be sensitive to the emitted fluorescent wavelengths.
Do fish like that exist? Earlier this year, researchers at the American Museum of Natural History were photographing their own corals’ fluorescence when they accidentally noticed one of their eels was fluorescing too. No one had noticed because the fluorescence is usually masked in the presence of broad visible light as seen by us land-lubbers.
It turns out that fluorescence in fish is surprisingly common. Water filters out long and medium wavelength light (reds and yellows) as it gets deeper, which is why it’s blue. To compensate for this limited spectral availability, fish have turned to fluorescence as a way to expand the wavelengths of communication and camouflage in their normally azure-monochrome world.
A Diamond Bigger Than The Moon
The biggest known diamond in the universe is 10-billion-trillion-trillion-carat (a one followed by 34 zeroes), and it’s right above Australia. Well, technically it’s 50 light years away in the constellation of Centaurus, right next to the Southern Cross, but let’s not be picky. Discovered on Valentine’s Day in 2004, the gem is actually the interior of a dead star: a white dwarf that used up all its nuclear fuel and collapsed in on itself, creating enormous pressures that crystallised its carbon core.
The cosmic jewel is hidden below a thin layer of hydrogen and helium gases, and it measures 4000 kilometres across and weighs 2.27 million trillion trillion kilograms. “You would need a jeweller’s loupe the size of the Sun to grade this diamond,” said Travis Metcalfe, who led the research into this star at the Harvard-Smithsonian Centre for Astrophysics. The largest diamond on Earth—the 530-carat Star of Africa—doesn’t stand a chance against this one. Don’t even think about slipping it on your fiancé’s ring finger.
In five billion years time, our own Sun will reach the end of its life and become a white dwarf, then after that its core will crystallise as well, leaving a giant diamond in the centre of our solar system.
Except our sun isnt large enough to burn it’s helium core (after hydrogen fusion is complete) to form lithium. Therefore our sun will never have a carbon core and thus, no diamond core. Sorry to “shatter” your dreams.
(3D printing) Darwin’s Cladogram Tree with Finches, by Joaquin Baldwin:
"Charles Darwin’s first ever sketch of a tree of life, in the shape of an actual tree, with finches perched on the branches. Each branch and minute detail of Darwin’s original drawing is represented, and each finch represents the A, B, C and D marks on his sketch. The sketch appeared in his private notebook (“Notebook B on the transmutation of species,” 1837–1838).
If you look carefully, you’ll notice that each finch is slightly different, and the more apart they are from each other in the evolutionary tree, the more distinct the differences are.”
