Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure has been lacking. Now scientists at the University of California, Davis have identified new clusters of cells with…
We all learned this in DARE class. About the rats in a cage who can self-administer morphine who get addicted to the stuff, and then just hit that lever until they die. A seemingly keystone...

Still prints of this storm for purchase can be found on my gallery. Follow me on Instagram as well for storm photos and whatnot -> MikeOlbinski It took four years but I finally got it. A rotating supercell. And not just a rotating supercell, but one with insane structure and amazing movement. I’ve been visiting the...
A wild idea is one that many people think is obviously quite unlikely. I'd say at least a third of these wild ideas are likely true. (Parenthetic links are to more of my writings .)
University of Liège researchers discover a new planetary system around a particularly small and cool star.

One of my favourite Limited Audience Jokes (although technically it's actually a riddle) goes:
Researchers from Inserm and Université de Rennes recently identified a new bacterial toxin which they transformed into potent antibiotics active against various bacteria responsible for human infections.
Multisystem inflammatory syndrome in children (MIS-C), believed to be linked to COVID-19, damages the heart to such an extent that some children will need lifelong monitoring and interventions, said the senior author of a medical literature review published Sept. 4 in EClinicalMedicine, a journal of The Lancet. Case…
An unusual lottery result made the news recently: on October 1, 2022, the PCSO Grand Lotto in the Philippines, which draws six numbers from $latex {1}&fg=000000$ to $latex {55}&fg=000000$ a…

Română On the sixth day of our science advent, we would like to talk about a debunked concept in neuroscience. The purpose of this prompt and of science debunking, in general, is not to make fun of how scientists in the past got things so wrong and how we’re so much smarter now. The point […]
Just as the AGBT hype cycle was firing up (with me contributing multiple sparks), serial entrepreneur Jonathan Rothberg's latest sequencing ...
Web site content explains the modern view of entropy change and the dispersal of energy in a process (at a specific temperature). It has been selected for instructors in general and physical chemistry by Dr. Frank L. Lambert, Professor Emeritus (Chemistry) of Occidental College, Los Angeles.
For some time, I’ve argued that a common conception of AI is misguided. This is the idea that AI systems like large language and vision models are individual intelligent agents, analogous to human agents. Instead, I’ve argued that these models are “cultural technologies” like writing, print, pictures, libraries…
One of the three basic circuit elements just got a lot smaller for the very first time, in what promises to be a trillion-dollar…
By trapping light into tiny crevices of gold, researchers have coaxed molecules to convert invisible infrared into visible light, creating new low-cost detectors for sensing.
Running a biotech company is capital intensive, and this can make it intimidating to get started. Founders sometimes face a chicken and egg problem: how do you make progress without millions of dollars in funding, and how do you raise millions of dollars in funding without having made progress? However, it is quite…
Engineers used the flow of water over a crystal plate to generate a stable ring of plasma without a vacuum chamber or electromagnetic fields to contain it.
At NAB, I found a demo of Wi-Wi STAMP, a wireless time synchronization protocol that came out of Japan's NICT. Wi-Wi stands for Wireless 2Way interferometry, and it uses the 900 MHz band for picosecond-level time sync, and mm-level distance accuracy, in a tiny box, currently the size of a smartphone. The system is…
A club for Meccano enthusiasts in London, holding four meetings each year and a public Meccano Show in Falconwood.
If you're working on serious projects there are often serious risks. A lot of these can be mitigated by preventative measures and safety ge...
