With Google search results having been awful for some time now, I have to assume that Google Scholar results are also less satisfactory.

While I'm old enough to have been in undergrad before the WWW, I wasn't in grad school before the 21st c. For those of you old enough, how were you doing literature review of journal articles back in ye olde days? @academicchatter

Are our moral #values shaped by divine love or are they a result of biological requirements of human life?

THIS WEDNESDAY April 17 at #UniversityOfTexas #Austin, #philosophers Ben Bayer and Adam Lloyd Johnson #debate the origins and interpretation of #morality, focusing on differences between secular, scientific interpretations, and theological views.

So cool!

Great pics of new ocean species recently discovered!

“The team found that a school of #fish moving together in just the right way was stunningly effective at #noise reduction: A school of seven fish sounded like a single fish.

“A predator, such as a #shark, may perceive it as hearing a lone fish instead of a group,” Mittal said. “This could have significant implications for prey fish.” #biology #science

“The single biggest key to #sound reduction, the team found, was the synchronization of the school’s tail flapping—or actually the lack thereof.

If #fish moved in unison, flapping their tail fins at the same time, the sound added up and there was no reduction in total sound. But if they alternated tail flaps, the fish canceled out each other’s sound, the researchers found.” #Science

Fish swim in schools for stealth since 100 fish swimming together make less NOISE than an individual fish swimming alone 🤯

Scientists have documented five major mass extinction events in Earth’s history. Are we entering the sixth phase? Live Science has more on this unsettling notion, including why many researchers say yes. If you’re thinking of humans “clearing habitats, exterminating species and changing the climate,” you’re on the right path.

Planets directly influence one another, and the more massive they are, the larger their gravitational pull. Mars is a lot smaller than Earth, but new research says it has enough clout to create swirling vortices in our planet's oceans. Atlas Obscura explains:

RC2040 - Retro emulated Z80 CP/M computer kit
The RC2040 is a PI PICO emulated RC2014 kit, with CP/M-80. It is capable of running the stock ROM images currently supported by the RC2014 (except RomWBW) which gives you a number of monitors and ROM based BASIC.

SD card and Pico come programmed with the RC2040 Software and RC2014 ROMS and use the same FFS python transfer software as the SD card RC2014 kit.

This kit now has support for <span cla... Read More

😲 Viruses Finally Reveal Their Complex Social Life

New research has uncovered a social world of viruses full of cheating, cooperation and other intrigues, suggesting that viruses make sense only as members of a community.

Crabs, kelp and mussels: Argentina’s waters teem with life – could a fish farm ban do the same for Chile?

While the ecosystem is thriving off the coast of Argentina, the proliferation of salmon farms in Chile’s waters is threatening marine life, say critics

Weekend 🦐🦠
The ubiquitous tool of is the Plankton Net. The first documented use was by British surgeon Dr John Vaughan Thompson to catch the brightly coloured copepods Sapphirina and barnacle larvae. Darwin brought these nets on the HMS Beagle. Originally fine muslin, then silk, now are highly accurate sized meshes of nylon. Modern quantitative nets with removable cod-end have been standardized since late 1800s and named for Victor Hensen.

American astronomer Annie Jump Cannon died in 1941.

Cannon developed a system of stellar classification based on spectral characteristics, which became known as the Harvard Classification Scheme (she was one of the "Harvard Computers"). She classified hundreds of thousands of stars, organizing them by temperature and spectral characteristics. Her work laid the foundation for our understanding of stellar evolution and the composition of stars.

One of Cannon's most significant contributions was the creation of the Henry Draper Catalogue, which listed the spectral classifications of nearly 400,000 stars. She also developed the mnemonic device "Oh, Be A Fine Girl, Kiss Me" to help remember the spectral classes: O, B, A, F, G, K, M.

In 1925, she became the first woman to receive an honorary doctorate from Oxford University.

The Women Who Mapped the Universe and Still Couldn’t Get Any Respect

At the beginning of the 20th century, a group of women known as the Harvard Observatory computers helped revolutionize the science of astronomy.

“[w]e all get it that you write science articles every day. You do that in articles with your name on them. Wikipedia is not like that. [. . .] So for about the bazillionth time—no”

Scientists' desire for credit is crossing the line into self-promotion on Wikipedia.

These authors use an analysis of contested edits of Wikipedia pages on CRISPR, arguing the tension needs to be resolved, perhaps with guidelines:

The universe is a vast, wondrous and strange place. What would happen if you traveled through it in a straight line forever? Could you return to your starting point? The key lies in understanding the expanding universe. Simple, right? Big Think unpacks it all in this head-spinning article by Ethan Siegel that will have you asking what the original question was.

We blink thousands of times per day, mostly without even noticing it. Could the function improve our vision? A new study applied high-resolution tracking to investigate. Science Alert tells us what it revealed.

: "In a perspective paper published in Chemical Materials this week, Anthony Cheetham and Ram Seshadri of the University of California, Santa Barbara selected a random sample of the 380,000 proposed structures released by DeepMind and say that none of them meet a three-part test of whether the proposed material is “credible,” “useful,” and “novel.” They believe that what DeepMind found are “crystalline inorganic compounds and should be described as such, rather than using the more generic label ‘material,’” which they say is a term that should be reserved for things that “demonstrate some utility.”

In the analysis, they write “we have yet to find any strikingly novel compounds in the GNoME and Stable Structure listings, although we anticipate that there must be some among the 384,870 compositions. We also note that, while many of the new compositions are trivial adaptations of known materials, the computational approach delivers credible overall compositions, which gives us confidence that the underlying approach is sound.”

In a phone interview, Cheetham told me “the Google paper falls way short in terms of it being a useful, practical contribution to the experimental materials scientists.” Seshadri said “we actually think that Google has missed the mark here.”"
