AdamnSelene writes: A report in Bloomberg describes a draft executive order that will hit the tech industry hard and potentially change the way those companies recruit workers from abroad. The H-1B, L-1, E-2, and B1 work visa programs would be targeted by requiring companies to prioritize higher-paid immigrant workers over lower-paid workers. In addition, the order will impose statistical reporting requirements on tech companies who sponsor workers under these programs. The order is expected to impact STEM workers from India the most.
Penguinisto adds: If (perhaps when) the president follows through, his next move could limit or at least seriously alter the way H-1B visas are distributed, putting U.S. citizens at a higher priority, and possibly restricting H1-B visas tighter. From the article: “If implemented, the reforms could shift the way American companies like Microsoft, Amazon and Apple recruit talent and force wholesale changes at Indian companies such as Infosys and Wipro. Businesses would have to try to hire Americans first and if they recruit foreign workers, priority would be given to the most highly paid. “Our country’s immigration policies should be designed and implemented to serve, first and foremost, the U.S. national interest,” the draft proposal reads, according to a copy reviewed by Bloomberg. “Visa programs for foreign workers should be administered in a manner that protects the civil rights of American workers and current lawful residents, and that prioritizes the protection of American workers — our forgotten working people — and the jobs they hold.”
schwit1 quotes a report from Digital Trends: In this generation of self-starters and self-made women and men, do-it-yourself isn’t just an option, it’s a way of life. And if there’s not an app for that, chances are there’s a YouTube video for it. That was certainly the case for a woman named Cara Brookins, who is living proof that if you’re willing to learn, you absolutely can. In 2008, Brookins was in the midst of a family struggle, having left a husband she called “violent and abusive.” Looking to make a fresh start for herself, she took the idea of rebuilding quite literally, perhaps using the physical experience of constructing a house as an extension of her emotional and mental journey. Though she had no previous experience in construction or architecture, Brookins found a series of YouTube tutorials on building a home and got to work. Over the course of nine months, Brookins worked tirelessly with the help of her four children to build a new home for themselves. “I had rented this cabin for a Thanksgiving getaway,” the mother of four told CBS News. “And driving there, we passed this house that had been ravaged by a tornado. It was this beautiful dream house and it was sort of wide open. You don’t often get the opportunity to see the interior workings of a house, but looking at these 2x4s and these nails, it just looked so simple. I thought, “I could put this wall back up if I really tried. Maybe I should just start from scratch.'”
An anonymous reader quotes a report from The Verge: New research shows that oxygen from Earth could be journeying all the way out to the Moon, where it then gets lodged inside the lunar soil. It’s a process that’s likely been happening for 2.4 billion years, ever since oxygen formed around our planet, meaning the Moon’s soil may contain trapped particles from Earth’s ancient atmosphere. This oxygen exchange, detailed in a study published today in Nature Astronomy, supposedly occurs for just a few days during the Moon’s 27-day orbit. Most of the time, the Moon is constantly being blasted with solar wind — fast streams of charged particles emanating from the Sun. But for five days of every lunar orbit, the Moon passes into Earth’s magnetotail, the portion of the planet’s magnetic field that stretches outward away from the Sun. This tail shields the Moon from the solar wind, and allows charged oxygen ions from Earth to travel to the lunar surface, according to the study. That means the Moon — a dead rock incapable of supporting life — is being showered with the byproducts of life here on Earth. In fact, the source of most of the oxygen in our atmosphere is biological, created by plants during photosynthesis. It’s a process that experts have suspected for a while but haven’t been able to confirm until today. Researchers have also suggested that other atmospheric components, such as nitrogen and noble gases, are getting to the Moon this way based on lunar soil samples.
mmell writes: University of Utah scientists have created a prototype electronic lens which uses several technologies to customize the lens optics focusing on whatever the wearer is looking at. [Just like] the “oil lenses” in Frank Herbert’s Dune series of novels, the electronic lens (a transparent LCD) can have its index of refractivity modified by application of a small electric current. While I can conceive many uses for this technology (in spacecraft instruments, webcams/Handycams, handheld binoculars and telescopes for example), these were developed as a replacement for the progressive lenses — a.k.a. bifocals — which are worn by many with less than perfect eyesight. Many eyeglass wearers don’t tolerate bifocals well and I wonder if the adaptive optics in this prototype could relieve them of the need to carry multiple pairs of glasses? Whether they prove cost effective for the role of eyeglasses or not (and I can see no reason why they shouldn’t), the applications for this technology seem quite diverse and potentially even revolutionary. I wonder how long it will be before these are more than just a prototype?
Lysergic acid diethylamide (LSD) has been credited, in part, for the creation of the iPhone, the polymerase chain reaction, as well as some pretty abstract artwork. Since the drug is classified as a Schedule 1 substance in the U.S., it’s been more difficult for scientists to legally study the drug and learn about how it affects the brain. Therefore, when a study (or two) is published it makes the findings all the more fascinating. Two studies were published last week (one in Current Biology, the other in Cell) that examine how LSD produces such diverse effects and why the drug takes so long to wear off. The Scientist reports the findings from for the first study: For the Current Biology study, 21 volunteers were given a placebo, a small dose of LSD alone, or the same dose of LSD but with kentaserin, a serotonin 2A antagonist. Study participants who took the kentaserin reported virtually the same experiences as those who took the placebo, and fMRI brain scans confirmed similar brain activities across participants in both groups. The serotonin 2A antagonist “blocked all the effects of LSD, so it was like if people didn’t take any drugs,” coauthor Katrin Preller, neuroscientist at the Zurich University Hospital in Switzerland told The Verge. “All the typical symptoms — hallucinations, everything — were gone.”
As for why an LSD high lasts for so long, Angus Chen has written an in-depth report on PBS Newshour about the findings from the study published in Cell: LSD and other psychoactive drugs work by binding to specialized proteins called receptors on the surfaces of neural cells. On the receptor protein is a sculpted “pocket,” into which molecules with the right shape can fit and thus stick to the cell, where they initiate changes in the brain. But different substances can often fit into the same receptor. Many receptors that bind LSD and DMT, for example, also fit the natural chemical messenger serotonin — which is produced in the body and helps regulate mood. Figuring out how each drug interacts with the same receptor in a different way is key to understanding why an LSD trip lasts all day whereas an experience with extracted DMT is often over in 15 minutes or less. By freezing an LSD molecule bound to a single brain cell receptor as a crystal in a lab, researchers were able to get a 3-D x-ray image of the drug and the protein locked together. The image showed Bryan Rother, a pharmacologist at the University of North Carolina at Chapel Hill and senior author on the paper, and his co-authors something strange about the way LSD fit inside this receptor. Drugs typically come and go from receptor proteins like ships pulling in and out of a port. But when an LSD molecule lands on the receptor, the molecule snags onto a portion of the protein and folds it over itself as the molecule binds to the receptor. LSD seems to stimulate the receptor for the entire time it is trapped underneath the protein “lid,” Roth says. Proteins are in constant motion, so he thinks the lid eventually flops open, allowing the drug to fly out and the effects to wear off. But the team ran computer models that suggest it could take hours for that to happen. Until then, the trip goes on.
