With the help of the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Juliette Stecenko is exploring cosmology—a branch of astronomy that investigates the origin and evolution of the universe, from the Big Bang to today and into the future. As an intern through DOE’s Science Undergraduate Laboratory Internships (SULI) program, administered at Brookhaven by the Office of Educational Programs (OEP), Stecenko is using modern supercomputers and quantum computing platforms to perform astronomy simulations that may help us better understand where we came from.

Stecenko works under the guidance of Michael McGuigan, a computational scientist in the quantum computing group at Brookhaven’s Computational Science Initiative. The two have been collaborating on simulating Casimir energy—a small force that two electrically neutral surfaces held a tiny distance apart will experience from quantum, atomic, or subatomic fluctuations in the vacuum of space. The vacuum energy of the universe and the Casimir pressure of this energy could be a possible explanation of the origin and evolution of the universe, as well a possible cause of its accelerated expansion.

“Casimir energy is something scientists can measure in the laboratory and is especially important for nanoscience, or in cosmology, in the very early universe when the universe was very small,” McGuigan said.

Cassowaries are big flightless birds with blue heads and dinosaur-looking feet; they look like emus that time forgot, and they’re objectively terrifying. They’re also, along with their ostrich and kiwi cousins, part of the bird family that split off from chickens, ducks, and songbirds 100 million years ago. In songbirds and their relatives, scientists have found that the physical make-up of feathers produce iridescent colors, but they’d never seen that mechanism in the group that cassowaries are part of—until now. In a double-whammy of a paper in Science Advances, researchers have discovered both what gives cassowary feathers their glossy black shine and what the feathers of birds that lived 52 million years ago looked like.

“A lot of times we overlook these weird flightless birds. When we’re thinking about what early birds looked like, it’s important to study both of these two sister lineages that would have branched from a common ancestor 80 million or so years ago,” says Chad Eliason, a staff scientist at the Field Museum and the paper’s first author.

“Understanding basic attributes—like how colors are generated—is something we often take for granted in living animals. Surely, we think, we must know everything there is to know? But here, we started with simple curiosity. What makes cassowaries so shiny? Chad found an underlying mechanism behind this shine that was undescribed in birds. These kinds of observations are key to understanding how color evolves and also inform how we think about extinct species,” says Julia Clarke, a paleontologist at the Jackson School of Geosciences at the University of Texas at Austin and the paper’s senior author. Eliason began conducting research for this paper while working with Clarke at the University of Texas as part of a larger project funded by the National Science Foundation (NSF EAR 1355292) to study how flightless birds like cassowaries have evolved their characteristic features.

Neuroplasticity is the brain’s ability to change under the influence of experience and activities. Several aspects of neuroplasticity are noteworthy: neurogenesis (development of new nerve cells) and synaptogenesis (development of new contacts between nerve cells) among them. Neuroplasticity used to be thought of as a limited phenomenon, mostly restricted to the early years of life. More recently it has been demonstrated that neuroplasticity continues throughout life, even in advanced age. This provides the conceptual basis for a wide range of therapeutic efforts aiming to slow the detrimental effects of aging on the brain and to treat various brain disorders.

What are the factors influencing neuroplasticity? The question is compelling both as a scientific challenge and because of the therapeutic promise of neuroplasticity once we know how to control and harness it. Among such factors, the environmental factors influencing neuroplasticity are particularly intriguing. It turns out that a strong relationship exists between what people do with their brains and how their brains age.

Both anecdotal observations and formal research suggest that education confers a protective effect against dementia. Highly educated people are less likely to succumb to its effects. Robert Katzman was the first to note that the prevalence of dementia, including Alzheimer’s disease, is lower in people with advanced education. The MacArthur Foundation Research Network on Successful Aging sponsored a study of the predictors of cognitive change in older persons. Education emerged as by far the most powerful predictor of cognitive vigor in old age.

Education Saturday with Space Time.

Why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many physicists believe that the answer lies in a process known as quantum decoherence.

A team of researchers from Los Alamos National Laboratory, Sheffield Teaching Hospitals NHS and the Duke Human Vaccine Institute and Department of Surgery has found 14 mutations to the SARS-CoV-2 virus, one of which they suspect might be more easily spread. In the interest of speedy dissemination of findings, the group has uploaded their paper to the bioRxiv preprint server rather than waiting for peer review at another journal.

The work involved analyzing the genomes of the virus found in 6,000 infected people from around the globe. They focused most specifically on the virus genes that are responsible for producing the “spike protein,” which is the mechanism the virus uses to attach to human cells. In so doing, they found 14 mutations, but one they named D614G (also known as G614) stood out because it was found in almost all samples outside of China. It was also particularly notable because it appeared to replace a prior mutation called D614. They also noted that in the original outbreak in China, there were only D614 mutations. It was only after the virus began appearing in Europe that the G614 mutation emerged. They suggest that the fact that the G614 virus took over from the prior mutation could mean it is more easily spread.

I was confident enough to turn it in. However, I then was looking online and found out there’s a really easy way to find out if an essay was written by GPT-2. It’s to feed it to GPT-2 and if it’s able to predict the next words, then it was written by the AI. It’s easier to find out than normal plagiarism.

I knew that the business school had software that they were using to look out for plagiarism in all the essays that are turned in to their online platform, which is how I turned in my essays. So I was slightly worried that the company that sold them the anti-plagiarism software would have made an update.

I don’t think the professors even considered the possibility of GPT-2 writing the essays, but I was slightly worried that the company making the software added a module. But not that much.

Hate is hate. It is not limited by a political belief system or race.

An interesting cautionary note on the well-intentioned effort to supply personal protective equipment (PPE), such as masks, via 3D printing. I’ll confess that I have not thought through all the implications.

“One of the hospitals calls it ‘the garage PPE,’” said Sarah Boisvert, founder of 3D-printing school Fab Lab Hub, who works with hospitals to 3D-print materials. “This is a far more complicated problem than just making Christmas ornaments for your family.”

Lovett readily admits that he is not an expert. But he and others who want to help are stymied in part by a lack of clear government regulation around simple designs.
