18 Science Facts We Didn't Know at The Start of 2017

...I must say, #1 is quite surprising:

1. Lungs don't just facilitate respiration - they also make blood. Mammalian lungs produce more than 10 million platelets (tiny blood cells) per hour, which equates to the majority of platelets circulating the body.

The Sciences Sing a Lullabye


Physics says: go to sleep. Of course
you’re tired. Every atom in you
has been dancing the shimmy in silver shoes
nonstop from mitosis to now.
Quit tapping your feet. They’ll dance
inside themselves without you. Go to sleep.

Geology says: it will be all right. Slow inch
by inch America is giving itself
to the ocean. Go to sleep. Let darkness
lap at your sides. Give darkness an inch.
You aren’t alone. All of the continents used to be
one body. You aren’t alone. Go to sleep.

Astronomy says: the sun will rise tomorrow,
Zoology says: on rainbow-fish and lithe gazelle,
Psychology says: but first it has to be night, so
Biology says: the body-clocks are stopped all over town
and
History says: here are the blankets, layer on layer, down and down.

"I lately lost a preposition;
It hid, I thought, beneath my chair,
And angrily I cried, 'Perdition!
Up from out of in under there!'

Correctness is my vade mecum,
And straggling phrases I abhor,
And yet I wondered, 'What should he come
Up from out of in under for?'"

E = MC2

What was our trust, we trust not;
What was our faith, we doubt;
Whether we must or must not,
We may debate about.

The soul, perhaps is a gust of gas,
And wrong is a form of right;
But we know that Energy equals Mass
by the Square of the Speed of Light!

What we have known, we know not;
What we have proved, abjure;
Life is a tangled bowknot,
But one thing is still sure.

Come little lad; come little lass;
Your docile creed recite:
"We know that Energy equals Mass
by the Square of the Speed of Light!"

Predatory journals hit by “fake editor" sting

A Polish research team has found that many journals that they classified as "predatory" accepted the application of a nonexistent person to become an editor. In 2015, the researchers created a profile of a fictitious scientist named Anna O. Szust (Oszust is the Polish word for fraud) and applied on her behalf to 360 journals, 120 from each of three well-known directories: the JCR (journals with an official impact factor as indexed on Journal Citation Reports), the DOAJ (journals included on the Directory of Open Access Journals) and "Beall's list" (potential, possible or probable predatory open-access publishers and journals, compiled by University of Colorado librarian Jeffrey Beall). "Dr. Szust" was accepted by 40 on Beall's list and 8 on the DOAJ list. At least 12 conditioned acceptance on, or strongly encouraged, some form of payment or participation in a profit-making scheme. [Pisanski K and others. Predatory journals recruit fake editor. Nature 543:481-483, 2017] Predatory journals, which appear to exist primarily to extract money from authors, exhibit questionable marketing schemes, follow lax or nonexistent peer review, and lack scientific rigor and transparency. More than 10,000 publications appear to fit this description. Beall's list was removed from the University of Colorado Web site in January 2017. [Straumsheim C. No more 'Beall's List': Librarian removes controversial list of "predatory" journals and publishers, reportedly in response to "threats and politics." Inside Higher Ed, Jan 17, 2017] At the time of its removal, it had about 1,200 entries.

Originally posted by [livejournal.com profile] kavery at Рождественские открытки знаменитого биолога
Ух ты, что я нашла!

Тому, кто изучал биологию наверняка известно имя Эрнста Геккеля, ученого-биолога.

Если очень коротко , то вот первая строка из Википедии

Эрнст Ге́нрих Фили́пп А́вгуст Ге́ккель (нем. Ernst Heinrich Philipp August Haeckel; 1834—1919) — немецкий естествоиспытатель и философ. Автор терминов питекантроп, филогенез, онтогенез и экология.
Далее идет подробная статья о всех его открытиях.

Но кроме того, что он был ученым, он был прекрасным художником. Широко известен его "Атласа Природных Форм" (Kunstformen der Natur, 1904).

Но как оказалось, рисовал он не только сугубо научные вещи. Ему принадлежат рисунки рождественских открыток, в которых он использовал рисунки всяких разных природных форм. В конце 19 века тематика рождественских открыток была весьма разнообразной, и в это "странное" время праздников вполне подходящими изображениями на открытках были всякие диковинки.
Как вам такая тематика?

BREAKING NEWS: The FDA has granted accelerated approval to eteplirsen for the treatment of Duchenne muscular dystrophy! Decades of MDA research and investment have paid off with the first disease-modifying drug available to treat DMD.
We are filled with hope.
bit.ly/eteplirseninfo

(from the Muscular Dystrophy Association)
~~
Sarepta is seeking accelerated approval for eteplirsen for patients with DMD who have a confirmed mutation of the dystrophin gene
amenable to exon 51 skipping (≈13% of patients with DMD).

In such patients, skipping of exon 51 might restore the reading frame of dystrophin, increase the production of dystrophin, and lead to
a clinical benefit for patients.

(from the FDA proposal, which you may see here)

The genome of cultivated sweet potato contains Agrobacterium T-DNAs with expressed genes: An example of a naturally transgenic food crop

We communicate the rather remarkable observation that among 291 tested accessions of cultivated sweet potato, all contain one or more transfer DNA (T-DNA) sequences. These sequences, which are shown to be expressed in a cultivated sweet potato clone (“Huachano”) that was analyzed in detail, suggest that an Agrobacterium infection occurred in evolutionary times. One of the T-DNAs is apparently present in all cultivated sweet potato clones, but not in the crop’s closely related wild relatives, suggesting the T-DNA provided a trait or traits that were selected for during domestication. This finding draws attention to the importance of plant–microbe interactions, and given that this crop has been eaten for millennia, it may change the paradigm governing the “unnatural” status of transgenic crops.

Happy 98th birthday to pioneering NASA physicist and mathematician Katherine Johnson! One of the earliest women to join NASA, Johnson's skills in celestial navigation were renowned. Among other mathematical feats, she calculated -- by hand -- the launch window and trajectory for the 1961 space flight of Alan Shepard, the first American in space, and the 1969 Apollo 11 flight to the Moon. For her contributions to the space programs and for blazing a trail for women and African Americans at NASA, Johnson was presented with the Presidential Medal of Freedom, the country's highest civilian award, last year.

"In the 1940s, an elite team of mathematicians and scientists started working on a project that would carry the U.S. into space, then on to the moon and Mars. They would eventually become NASA's Jet Propulsion Laboratory (or JPL), but here's what made them so unusual: Many of the people who charted the course to space exploration were women. Nathalia Holt tells their story in her new book, 'Rise of the Rocket Girls' Holt tells NPR's Ari Shapiro that the women worked as 'computers.'

'In a time before the digital devices that we're used to today, it was humans that were doing the calculations,' she says. 'And so you needed these teams of people — many of whom were women, especially during World War II — and they were responsible for the math.'... Today, Holt says, 'There is hardly a mission that you can find in NASA that these women haven't touched.'"

Holt hopes that her new book will inspire girls and women of all ages to pursue their interests in science and technology: "My hope is that these women serve as role models, not just for my daughter of course, but for all of the women that are interested in science. It's a difficult time for women in technology right now. In 1984, 37 percent of all bachelor's degrees in computer science were awarded to women, and today that number has dropped to 18 percent. And even for women that are working in science today, it's about half of all women that leave midcareer. So I think these stories are important for inspiring and being role models that are so much needed for women today."
