IBM’s new quantum computer, Osprey, is more than triple the size of its previous record-breaking Eagle processor.
Coronaviruses have brought about three massive outbreaks in the past two decades. Each step of its life cycle invariably depends on the interactions among virus and host molecules. The interaction between virus RNA and host protein (IVRHP) is unique compared to other virus-host molecular interactions, and has emerged to be a very hot topic in recent studies.
These studies provide essential information for a deeper understanding of IVRHP, which represents not only an attempt by viruses to promote their translation/replication, but also the host’s endeavor to combat viral pathogenicity. In other words, there is an urgent need to have a panorama of coronavirus RNA-Host protein interactions, which will then aid in the discovery of new antiviral therapies.
On October 6, 2022, Prof. Zhu Feng from College of Pharmaceutical Sciences in Zhejiang University, Prof. Han Lianyi from College of Life Sciences in Fudan University and Prof. Lin Tao from College of Pharmaceutical Sciences in Hangzhou Normal University published an article titled “CovInter: Interaction Data between Coronavirus RNAs and Host Proteins” in Nucleic Acids Research.

A new study by author Cícero Moraes, a Brazilian graphics expert, 3D artist, and designer, reveals how a warrior may have died in the Battle of Gotland that took place between Swedish farmers and the Danish army in 1361.
More and more companies and scientists are working to equip contact lenses with applications that not long ago still seemed like science fiction, such as the ability to record videos or diagnose and even treat diseases. Mojo Vision, an American startup, is one company that has been improving its prototypes since 2015. It is currently developing an ambitious project involving augmented reality lenses that, in addition to correcting your vision, will let you consult all kinds of information, from the trails on a ski slope to your pace when you run, all through microLED displays the size of a grain of sand.
“In the short term, it sounds like a futuristic idea, but 20 years ago we couldn’t even imagine many of the technological advances that we have today,” says Ana Belén Cisneros del Río, deputy dean of the College of Opticians-Optometrists in the Spanish region of Castilla y León, of the Mojo Vision project. However, Daniel Elies, a specialist in cornea, cataract and refractive surgery and medical director of the Institute of Ocular Microsurgery (IMO) Miranza Group in Madrid, does not believe that this type of contact lens will become part of everyday life anytime soon, “especially due to cost issues.”
One of the companies interested in manufacturing augmented reality contacts is Magic Leap. Sony, for its part, applied a few years ago for a patent for lenses that can record videos, and Samsung did the same for lenses equipped with a camera and a display that projects images directly into the user’s eye. Some researchers are trying to create robotic lenses that can zoom in and out with the blink of an eye, and yet others are working on night vision contact lenses, which could be useful in military applications.

Louis A. Del Monte.
Nearly invisible weapons of mass destruction.
Nanoweapons just might render humanity extinct in the near future—a notion that is frightening and shocking but potentially true. In Nanoweapons Louis A. Del Monte describes the most deadly generation of military weapons the world has ever encountered. With dimensions one-thousandth the diameter of a single strand of human hair, this technology threatens to eradicate humanity as it incites world governments to compete in the deadliest arms race ever.
On the one hand, from the dawn of civilization humans have dreamed of immortality. On the other hand, from the dawn of civilization a myriad of anti-aging remedies turned out to be empty promises. Even worse, they often shorten lifespan. Two notable examples are antioxidants and human growth hormone. The idea that free radicals, or reactive oxygen species (ROS), cause aging was based on a “wild guess,” as Harman, a father of the ROS theory, acknowledged when he titled his paper, “I thought, thought, thought for four months in vain and suddenly the idea came” [116]. The idea is simple and intuitive, and it was widely accepted based on circumstantial evidence. In fact, ROS are inevitable products of metabolism, and they do damage biomolecules. Moreover, excessive ROS can shorten lifespan. Similarly, the atomic bomb can shorten life span. Yet this does not mean that either atomic bombs or oxidants are the cause of normal aging as we know it.
Numerous experiments support the ROS theory. However, key experiments ruled the ROS theory out (see for references [2, 117 – 122]. To make a long story short, antioxidants could in theory prolong lifespan if mTOR-driven (quasi-programmed) aging were suppressed and we lived long enough to die from ROS-induced post-aging syndrome (I will discuss the nuances in the forthcoming article “ROS and aging revisited”). Indeed, ROS will kill any organism eventually. However, organisms normally die from mTOR-driven, age-related diseases (aging as we know it) before ROS can kill them (see for discussion [2]). As an analogy, consider most of the passengers on the Titanic. Would antioxidant treatment have been useful to them for life extension? The best way to extend life for members of that group would have been to carry more life boats. Only after their safe rescue could one expect antioxidants to potentially increase their life further. Similarly, only after rescue from the quasi-program of aging may antioxidants potentially have an impact.
From swerving to sheltering in place, here’s how the International Space Station handles hazards on the increasingly cluttered space lanes.
The most recent maneuver happened last week when the ISS boosted itself into a higher orbit to avoid debris from a 2021 Russian anti-satellite missile test. It’s likely that such close calls will only get more common as humanity keeps cluttering up the space lanes with old satellites and bits of wreckage from collisions and missile tests. Here’s what you need to know about space debris and how to avoid it.
How does the International Space Station dodge space debris?

The project, known as DAF-MIT AI Accelerator, selected a pilot out of over 1,400 applicants.
The United States Air Force (DAF) and Massachusetts Institute of Technology (MIT) commissioned their lead AI pilot — a training program that uses artificial intelligence — in October 2022. The project utilizes the expertise at MIT and the Department of Air Force to research the potential of applying AI algorithms to advance the DAF and security.
The military department and the university created an artificial intelligence project called the Department of the Air Force-Massachusetts Institute of Technology Artificial Intelligence Accelerator (DAF-MIT AI Accelerator).
