I read that labs in Japan and Russia have recently started attempts to produce atoms of element 119, to be followed by element 120. I suppose they could do it in either order. They're both getting raw materials from ORNL (Oak Ridge National Laboratories), for one of the isotopes they need for this, the one that is itself an artificial element that has to be made in a laboratory. If successful this would start a new row on the table, giving it a total of 8 rows. (In school I was taught that it had just 7 rows.)

The article said that elements passed 120 may be beyond current technology, because their expected half lives are so short, and any atoms they produced would decay before they got in range of the detectors. Of course, all they detect for any of these really heavy elements is the decay products from nuclei that no longer exist when the decay products are detected, but still.

On interesting tidbit here is that for the last dozen or so elements added to the table, they can count the number of atoms that have been detected.

Count them?  They could name them.

A couple of years ago, scientists discovered an enzyme in a waste recycling center in Japan that digests plastic. During a recent experiment to understand how this enzyme works, scientists accidentally created a mutated version that breaks down plastic even better than the one found in nature.


ID Creationist Response #1: How did a random mutation improve the function? Fake News!!!!

ID Creationist Response #2: The scientists were intelligent designers of the experiment, so it's really proof of ID!!!!

I'm not sure which one they'll gravitate towards, because I can't tell which is more retarded.

Inspired by that numbnut who said CO2 doesn't trap heat, which has been known to be wrong since 1896, I wondered what the temp of Earth would be without greenhouse gases. This is interesting:

Quote
At present, roughly 30% of the incoming solar radiation is reflected back to space by the clouds, aerosols, and the surface of Earth. Without naturally occurring greenhouse gases, Earth's average temperature would be near 0°F (or -18°C) instead of the much warmer 59°F (15°C).

Fewer Australian university students than ever before believe in creationism

Australian university students appear to give far more credit to the science of human evolution and far less to creationism or divine guidance than the previous generation. This is according to our 32-year-long annual survey of first-year biology students at UNSW in Sydney.

Belief among students that God is the ultimate or contributing cause of human origins has steeply declined. It was a majority view in 1986, and now a minority view in 2017. Conversely, the belief that humans evolved without divine involvement of any kind rose steeply over the same period to become the dominant view.

Reasons for these significant changes over time may include increasing access to the web, increasing scientific evidence for evolution, and/or growing scepticism about claims for supernatural miracles of any kind.

What is creationism?
In most Western countries creationism involves belief the Bible, and in particular the Book of Genesis, is a correct and factual account of how the universe and life came into being. Accordingly, their common view is that God created the universe and all kinds of animals and plants within a single seven day week less than 10,000 years ago.

Adam and Eve were constructed on day six of this creation week. God made Adam from dust and Eve from one of Adam’s ribs. Both were placed in the Garden of Eden where they lived alongside, among other things, herbivorous lions (there was no death until Adam sinned, dinosaurs and all other kinds of animals known and unknown, including talking snakes.


Commonly, more than 40% of Americans hold fast to these convictions and refuse to accept that evolution has occurred, let alone that humans evolved over millions of years from other kinds of animals.

In contrast, most people who believe in God but not literal creationism accept that it should be the business of science to research the nature and origin of the natural world, and it should be the business of religion to focus on life’s meaning and purpose.

Most mainstream theists – those who believe in the existence of one or more gods – don’t see a major conflict between their religious beliefs and understanding about the reality of evolution. Accepting that the Genesis account may be an allegory, they see no major problem in accepting the possibility that evolution was God’s method of creation.

The survey
We began a survey of student attitudes in 1986 in order to assess the level of a commitment among incoming students to supernatural explanations for our origins. From 1986 to 2017, every student attending our first-year biology course was invited to complete a one item poll on a strictly anonymous basis.

An average of 530 students a year participated in the survey. The results of the each year’s survey – and those of all previous years – were openly presented to and discussed with that year’s class in the following lecture.

Each student was handed a slip of paper as they walked into the classroom and was asked to circle one of the following four options, the one they agreed with most:

God created people (Homo sapiens) pretty much in their present form at some time within the last 10,000 years (literal creationism)

people developed over millions of years from less advanced forms of life, but God guided the whole process, including our development (creationism through evolution)

people developed over millions of years from less advanced forms of life. God had no part in this process (evolution)

I honestly have no opinion about this matter.

This wording closely adheres to that commonly used for many years in Gallop polls conducted in the US.

The results
We found the percentage of our students who chose the literal creationism option has been consistently small (about four times smaller than the percentage commonly endorsing this option in the US). In 1986, only 10% of the class believed in creationism. This slowly declined by more than 50% to less than 5% in 2017.


More surprising, there was a significant inversion over time in the percentage of students embracing and those rejecting a role for God in the origin of humans. In 1986, the majority (60%) of our students believed God had something to do with the origin of humans. In 2017, this view was embraced by only a small minority (29%) of the class, a decrease of about 50% over the 32 year interval. The percentage of students convinced that God had nothing to do with the origin of humans increased from a small minority (25%) in 1986 to the clear majority view (62%) in 2017.

A broader shift
The Australian public census appears to reflect similar directions of change in the Australian public in general. The percentage of Australians who indicated they had “no religion” on the Census rose from 22.3% in 2011 to 30.1% in 2016.

From Australian Social Trends, November 2013. ABS
In the same time period, the percentage of students selecting “God had no part in the evolution of humans” on our survey rose from 52.1% in 2011 to 62.4% in 2016. This suggests the results from our 32 year survey may reflect at least similar directions of change in the Australian public as a whole.

Australia has a less religious past than some
Reports of long-term trends in views about the origins of humans are rare and, in most cases, limited to surveys of adult populations in the US. More rare are surveys of these beliefs in other countries.

The extent and pace of decline in the Australian students’ commitment to religious views about divine creation contrast with the views held by the American public.

Significant differences between the balance of views in the US and Australia may in part reflect different cultural backgrounds. Most of the early Europeans who travelled to North America were deeply religious Protestants. In contrast, most Europeans who moved to Australia, some as “guests” of Her Majesty’s prison system, were far less concerned with religious matters and far more inclined to spend Sundays at the pub.

The first Christian cleric in Australia, Reverend Richard Johnson who sailed with the First Fleet, had an incredibly hard time trying to raise funds to build any form of church. He ended up paying for the building out of his own wages.

His church was finally built in 1794 but, shortly after completion, was deliberately burned down. After losing the church and much of his own income, Reverend Johnson filed for a leave of absence to visit England. He never returned.

Understanding the broader shift
A key factor cited by many which may be contributing to the long-term shift away from theistic views of human origins include increasing access to a massive amount of web-based and media-presented scientific understanding about the origin of the natural world. Before this was available, cultural, community and parental values may well have been the most influential factors in forming student opinions about supernatural versus natural origins.

But it may also be that people are finding it difficult to maintain faith in miraculous explanations for what are otherwise increasingly found to be natural phenomena. Exposure of claims for contemporary miracles, such as statues of Mary that appear to weep tears of blood, don’t help to stem growth in scepticism about miracles in general.

We will continue to run this survey in UNSW Sydney for as long as practical. But it would be interesting to begin the same type of long-term survey program in the range of secondary schools that contribute most of the students to UNSW Sydney.

Similarly, it would be interesting to see long-term annual surveys of this kind conducted in other tertiary education institutions in Australia, and overseas. It’s always possible (although unlikely) that our students’ opinions are not broadly representative of Australian first-year university students as a whole. Having similar data from other institutions would give us a more nuanced view.

Finally, it would be interesting, if possible, to ask the same question of the same cohort of students in third-year to see if a university education results in a change in opinion among those who arrived with creationist views.

Professor Mike Archer was the lead author of a team of scientists who conducted and interpreted the results reported here. The others are (in order of authorship): Associate Professor Alistair G.B. Poore (UNSW Sydney); Ms Alexis M. Horn (Sanibel-Captiva Conservation Foundation); Dr Hayley Bates (UNSW Sydney); Assoc. Prof. Stephen Bonser (UNSW Sydney); Matthew Hunt (Charles Sturt University); Jonathan Russell (UNSW Sydney); Nikkita P. Archer (37a Hannam St, Bardwell Valley); Dylan J. Bye (37a Hannam St, Bardwell Valley); Prof. E. James Kehoe (UNSW Sydney).

Course, it's kind of hard to measure the amount of variety when the most we can get at this distance is some kind of spectroscopic analysis (i.e., what chemicals are present in that environment).

Interesting evolution related news at Slashdot:

Human Speech May Have a Universal Transmission Rate: 39 Bits Per Second

sciencehabit writes: Italians are some of the fastest speakers on the planet, chattering at up to nine syllables per second. Many Germans, on the other hand, are slow enunciators, delivering five to six syllables in the same amount of time. Yet in any given minute, Italians and Germans convey roughly the same amount of information, according to a new study. Indeed, no matter how fast or slowly languages are spoken, they tend to transmit information at about the same rate: 39 bits per second, about twice the speed of Morse code. "This is pretty solid stuff," says Bart de Boer, an evolutionary linguist who studies speech production at the Free University of Brussels, but was not involved in the work. Language lovers have long suspected that information-heavy languages -- those that pack more information about tense, gender, and speaker into smaller units, for example -- move slowly to make up for their density of information, he says, whereas information-light languages such as Italian can gallop along at a much faster pace. But until now, no one had the data to prove it.

Latent developmental potential to form limb-like skeletal structures in zebrafish

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.

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.
