I just finished Neil Shubin's latest book Some Assembly Required on the history and current state of DNA research into evolutionary origins.   This paper is the icing on the cake.  :)

Cool, I will have to go look for that, thanks!

Well this is simply the most astonishing discovery that I can recall. A bacteria that photosynthesises from INFRARED LIGHT FROM A DEEP SEA HYDROTHERMAL VENT.

I thought infrared wouldn't get that far down?

Perhaps it is generated in the hydrothermal vent itself.  They are hot after all.

Yes, but that one comes a bit closer than the one in Kentucky!

What with climate change, they'd better get that sorted before the whole of East Anglia disappears beneath the waves.

Study: Evolution now accepted by majority of Americans

The level of public acceptance of evolution in the United States is now solidly above the halfway mark, according to a new study based on a series of national public opinion surveys conducted over the last 35 years.

“From 1985 to 2010, there was a statistical dead heat between acceptance and rejection of evolution,” said lead researcher Jon D. Miller of the Institute for Social Research at the University of Michigan. “But acceptance then surged, becoming the majority position in 2016.”

Examining data over 35 years, the study consistently identified aspects of education—civic science literacy, taking college courses in science and having a college degree—as the strongest factors leading to the acceptance of evolution.

“Almost twice as many Americans held a college degree in 2018 as in 1988,” said co-author Mark Ackerman, a researcher at Michigan Engineering, the U-M School of Information and Michigan Medicine. “It’s hard to earn a college degree without acquiring at least a little respect for the success of science.”

The researchers analyzed a collection of biennial surveys from the National Science Board, several national surveys funded by units of the National Science Foundations, and a series focused on adult civic literacy funded by NASA. Beginning in 1985, these national samples of U.S. adults were asked to agree or disagree with this statement: “Human beings, as we know them today, developed from earlier species of animals.”

The series of surveys showed that Americans were evenly divided on the question of evolution from 1985 to 2007. According to a 2005 study of the acceptance of evolution in 34 developed nations, led by Miller, only Turkey, at 27%, scored lower than the United States. But over the last decade, until 2019, the percentage of American adults who agreed with this statement increased from 40% to 54%.

The current study consistently identified religious fundamentalism as the strongest factor leading to the rejection of evolution. While their numbers declined slightly in the last decade, approximately 30% of Americans continue to be religious fundamentalists as defined in the study. But even those who scored highest on the scale of religious fundamentalism shifted toward acceptance of evolution, rising from 8% in 1988 to 32% in 2019.

Miller predicted that religious fundamentalism would continue to impede the public acceptance of evolution.

“Such beliefs are not only tenacious but also, increasingly, politicized,” he said, citing a widening gap between Republican and Democratic acceptance of evolution.

As of 2019, 34% of conservative Republicans accepted evolution compared to 83% of liberal Democrats.

The study is published in the journal Public Understanding of Science.

Besides Miller and Ackerman, the authors are Eugenie Scott and Glenn Branch of the National Center for Science Education; Belén Laspra of the University of Oviedo in Spain; and Carmelo Polino of the University of Oviedo and Centre Redes in Argentina; and Jordan Huffaker of U-M.

PBS Nova had a show last night, about that pesky anti-dinosaur asteroid of 66 million or so years ago.

Seems they found a group of fossils in the Dakotas that look likely to have been killed BY the effects of the asteroid. And the Dakotas are some 2000 miles from the Yucatan.

Ouch!

I wonder if the search for elements 119 and/or 120 was blocked by the pandemic, or has that been running continuously for the last 4 years. As I recall, one scientist in Japan thought they'd have them within 5 years. But I haven't seen any updates since then.

NASA, DARPA Will Test Nuclear Engine for Future Mars Missions

https://www.nasa.gov/press-r....issions

I guess their efforts to produce a nuclear fusion rocket weren't moving fast enough (er, so to speak).
That proposed design would have fused H2 with He3, and used solid Li for both propellant and insulation between plasma and container walls.

I guess, whether fusion or fission, they expect a one way trip time of maybe 3 or 4 months, round trip 7 to 9 months.

That's in lots of contrast to a mission using chemical rockets (8-9 months each way, and once there a 16+ month wait for the next launch window for the return trip).

https://en.wikipedia.org/wiki....elium-4

The article says: "The stability of helium-4 is the reason that hydrogen is converted to helium-4, and not deuterium (hydrogen-2) or helium-3 or other heavier elements during fusion reactions in the Sun."

But I thought small stars like our sun produce more He-3 than He-4.

DePalma's 'Hell Creek' stuff? I read an article on that recently. It sounds like he has a site that has abnormal diversity for a layer with incorporated tektites. He was interpreting this as the post-impact tsunami depositing a lot of dead and dying marine biota in a marshy/boggy area.

As of yesterday, NASA has 250 grams of asteroid material to study.

The webelements.com site shows 83 Bismuth as stable, but I've heard that they've changed their minds about that, making it out of date on that point.

Somebody found that Bi 209 has a half life of around 2.01 * 10 ** 19 years (i.e., don't wait up for it to be half gone).
