Forget What You Learned in High School
Posted by Shane Hinshaw in categories: chemistry, education
It’s the stuff of Chemistry 101: carbon can only form four bonds because it only has four shareable electrons.
But this rule no longer applies, because scientists have confirmed the existence of an exotic carbon molecule that can form six bonds, meaning the most classic example of tetravalence in our high school chemistry textbooks now comes with a hefty caveat.
If all of this is kinda giving you conniptions, we’re right there with you.

Biologists discover how viruses hijack cell’s machinery
Posted by Shane Hinshaw in category: biotech/medical
Looks like hacking might be alot older then we thought lmao.
Biologists at UC San Diego have documented for the first time how very large viruses reprogram the cellular machinery of bacteria during infection to more closely resemble an animal or human cell—a process that allows these alien invaders to trick cells into producing hundreds of new viruses, which eventually explode from and kill the cells they infect.
In a paper published in the January 13 issue of Science, the researchers conducted a series of experiments that allowed them to view in detail what happens inside bacterial cells as the invading viruses replicate.

Salmonella Could Be Used To Fight Brain Tumors
Posted by Karen Hurst in categories: biotech/medical, neuroscience
Over millions of years retroviruses have been incorporated into our human DNA, where they today make up almost 10 per cent of the total genome. A research group at Lund University in Sweden has now discovered a mechanism through which these retroviruses may have an impact on gene expression. This means that they may have played a significant role in the development of the human brain as well as in various neurological diseases.
Retroviruses are a special group of viruses including some which are dangerous, such as HIV, while others are believed to be harmless. The viruses studied by Johan Jakobsson and his colleagues in Lund are called endogenous retroviruses (ERV) as they have existed in the human genome for millions of years. They can be found in a part of DNA that was previously considered unimportant, so called junk-DNA — a notion that researchers have now started to reconsider.
“The genes that control the production of various proteins in the body represent a smaller proportion of our DNA than endogenous retroviruses. They account for approximately 2 per cent, while retroviruses account for 8–10 per cent of the total genome. If it turns out that they are able to influence the production of proteins, this will provide us with a huge new source of information about the human brain,” says Johan Jakobsson.

Next-Gen Computing Game Changers: Quantum Computers And Beyond
Posted by Karen Hurst in categories: computing, quantum physics
Although this was published last week; I got a request to share again for those who missed it.
While “product-market fit” may have become the mantra for many tech companies and investors, we believe there are still plenty of companies out there with their eyes set on building true game-changing technologies. In our Game Changers report, we identified 8 categories of innovation that could have the greatest impact on how we live. Among these is next-gen computing — specifically, quantum computers and DNA data-writing technologies, which have the potential to fast-track innovation across industries.
Quantum computers can solve real-world problems much faster than traditional computers — and their capacity is only increasing. Meanwhile, using synthetic DNA to store vastly more data than a typical chip has the potential to revolutionize computers’ memory capacity.

Greek scientists create artificial neuron with quantum-dot lasers
Posted by Karen Hurst in categories: biological, quantum physics, robotics/AI
Syn. Neurons via Q-Dot Laser. Nice.
Greek researchers working at the National and Kapodistrian University of Athens (EKPA) optical communication photonic technology laboratory have developed an artificial “neuron” that simulates fundamental functions of the human brain, at speeds that are many orders of magnitude higher.
A paper on the new breakthrough made by the Greek team, led by Prof. Dimitris Syvridis with Dr. Charis Mesaritakis as main researcher and with Alexandros Kapsalis and Adonis Bogris listed as authors, was published in the “Scientific Reports” section of the science journal “Nature” on December 19.
