Viral Budding of the SARS-CoV-2 virus — NanoBiology Course 2020 — Tuesday Group

Posted by in categories: biotech/medical, chemistry, particle physics

In this video students of the Maastricht Science Program NanoBiology Course 2020, show their explanation of the SARS-CoV-2 viral budding. Using CellPAINT, UCFS Chimera and their creativity they explain the nanobiology of how the SARS-CoV-2 virion can bud and leave the cell.

Viruses are not living things. They are just complicated assemblies of molecules, in particular macromolecules such as proteins, oligonucleotides, combined with lipids and carbohydrates. A virus cannot function or reproduce by itself. It needs a host cell.

A Virus Attacks a Cell

“Like a lock and key” — this is the description of how viruses can get into our cells. Viruses use special proteins on their surface to enter cells. They do this because they need our cells to reproduce. But viruses can only enter certain cells. They use proteins on their surface that act like keys to unlock human cell receptors to invade and infect cells.

Physicists Say Aliens May Be Using Black Holes as Quantum Computers

Posted by in categories: alien life, computing, existential risks, quantum physics

If life is common in our Universe, and we have every reason to suspect it is, why do we not see evidence of it everywhere? This is the essence of the Fermi Paradox, a question that has plagued astronomers and cosmologists almost since the birth of modern astronomy.

It is also the reasoning behind the Hart-Tipler Conjecture, one of the many (many!) proposed resolutions, which asserts that if advanced life had emerged in our galaxy sometime in the past, we would see signs of their activity everywhere we looked. Possible indications include self-replicating probes, megastructures, and other Type III-like activity.

U.S. SEC targets crypto ‘staking’ with Kraken crackdown

Posted by in category: cryptocurrencies

Feb 9 (Reuters) — (This Feb. 9 story has been refiled to add ‘U.S.’ in the first sentence to reflect the closure of the U.S. service only)

Crypto exchange Kraken agreed to shut down its U.S. cryptocurrency staking service and pay $30 million in penalties to settle U.S. Securities and Exchange Commission charges that it failed to register the program, the agency said on Thursday, in a move that could cause headaches for platforms with similar offerings.

The settlement marks the SEC’s first crackdown on staking, a common service offered at both centralized and decentralized crypto exchanges, including most of the major exchanges in the United States such as Coinbase (COIN.O) and Binance US.

Changes in how the heart produces energy may be the earliest signal of cardiac deterioration

Posted by in category: biotech/medical

Heart failure is often identified only when the heart has already deteriorated. This is in large part because the cause is unknown for about 70% of people who experience heart failure.

Researchers at The Hospital for Sick Children (SickKids) have discovered that one of the earliest signs of is a change in how the produces , with findings offering a potential way to preempt heart failure before the heart begins to deteriorate.

Led by Dr. Paul Delgado-Olguín, a scientist in the Translational Medicine program, the research may also help to explain the diversity of causes underlying heart failure.

AI is putting our jobs as architects unquestionably at risk

Architects urgently need to get to grips with the existential threat posed by AI or risk, in ChatGPT’s words, “sleepwalking into oblivion”, writes Neil Leach.

In the near future, architects may become a thing of the past. Artificial intelligence (AI) is quickly advancing to a point where it can generate the design of a building completely autonomously. With the potential to create designs faster and with more accuracy than ever before, AI has the potential to revolutionize the architecture industry, leaving traditional architects out of the equation. This could spell the end of the profession as we know it, raising questions of what the future holds for architects in a world of AI-generated buildings.

ChatGPT passes gold-standard US medical exam

Posted by in categories: biotech/medical, employment, robotics/AI

ChatGPT has passed the gold-standard exam required to practice medicine in the US — amid rising concerns AI could put white-collar workers out of jobs.

The artificial intelligence program scored between 52.4 and 75 percent across the three-part Medical Licensing Exam (USMLE). Each year’s passing threshold is around 60 percent.

Researchers from tech company AnsibleHealth who did the study said: ‘Reaching the passing score for this notoriously difficult expert exam, and doing so without any human reinforcement, marks a notable milestone in clinical AI maturation.’
