As we approach two full years of the COVID-19 pandemic, we now know it spreads primarily through airborne transmission. The virus rides inside tiny microscopic droplets or aerosol ejected from our mouths when we speak, shout, sing, cough, or sneeze. It then floats within the air, where it can be inhaled by and transmitted.

This inspired researchers in India to explore how we can better understand and engineer airflow to mitigate the transmission of COVID-19. To do this, they used their knowledge of airflow around aircraft and engines to tailor the airflow within indoor spaces.

In Physics of Fluids, they report computer simulations of airflow within a public washroom showing infectious aerosols in can linger up to 10 times longer than the rest of the room. These dead zones of trapped air are frequently found in corners of a room or around furniture.

Good day to you all.

What about living in a time when you can eat meat that does not mean an animal was killed, or even mildly hurt?

What about an era with dairy with no animals involved, aside from some DNA donation in return for a grassy field, protection and regular meals and shelter when needed…?

Sound like science fiction?

Advances in Artificial Intelligence, neuroscience and robotics have gotten us to a point where people might want to replace their biological limbs with robotic limbs due to there being more and more advantages with every passing day. Things like improved movement, intelligent controlling systems with the help of machine learning AI can help you control these limbs better than you could control your regular old arms, legs and hands.

But how long until we can finally live out our transhuman fantasies and become cyborgs? All this, and a bunch of new and futuristic scientific discoveries in this one review showcasing the most advanced AI Controlled Prosthetics.

Speaker:
James L. Burk.
Commander, MDRS Crew 261.
Executive Officer, MDRS Crew 197.
Director of IT & MarsVR, The Mars Society.
Former Senior Technical Project Manager, Microsoft.

Track Code: AM-2

Abstract:
James Burk will be the commander of MDRS Crew 261 composed of professional analog astronauts from the US, Canada, France and Belgium. As part of the preparation for MDRS Crew 261 (Dec 2021), our crew held a call for experiments across the space analog science community. We selected 10 experiments which run the gamut of the disciplines of medicine, chemisty, biology, robotics, sociology, psychology and human factors challenges for a human Mars mission. James will present our roster of experiments and our plan for executing them during our mission in December.

From the 24th Annual International Mars Society Convention, held as a Virtual Convention worldwide on the Internet from October 14–17, 2021. The four-day International Mars Society Convention, held every year since 1,998 brings together leading scientists, engineers, aerospace industry representatives, government policymakers and journalists to talk about the latest scientific discoveries, technological advances and political-economic developments that could help pave the way for a human mission to the planet Mars.

Conference Papers and some presentations will be available on www.MarsPapers.org.

A team of physicists has discovered how DNA molecules self-organize into adhesive patches between particles in response to assembly instructions. Its findings offer a “proof of concept” for an innovative way to produce materials with a well-defined connectivity between the particles.

The work is reported in Proceedings of the National Academy of Sciences.

“We show that one can program particles to make tailored structures with customized properties,” explains Jasna Brujic, a professor in New York University’s Department of Physics and one of the researchers. “While , drills, and hammers must be controlled by humans in constructing buildings, this work reveals how one can use physics to make that ‘know’ how to assemble themselves.”

The device you are currently reading this article on was born from the silicon revolution. To build modern electrical circuits, researchers control silicon’s current-conducting capabilities via doping, which is a process that introduces either negatively charged electrons or positively charged “holes” where electrons used to be. This allows the flow of electricity to be controlled and for silicon involves injecting other atomic elements that can adjust electrons—known as dopants—into its three-dimensional (3D) atomic lattice.

Silicon’s 3D lattice, however, is too big for next-generation electronics, which include ultra-thin transistors, new devices for optical communication, and flexible bio-sensors that can be worn or implanted in the human body. To slim things down, researchers are experimenting with materials no thicker than a single sheet of atoms, such as . But the tried-and-true method for doping 3D silicon doesn’t work with 2D graphene, which consists of a single of carbon atoms that doesn’t normally conduct a current.

Rather than injecting dopants, researchers have tried layering on a “charge-transfer layer” intended to add or pull away electrons from the graphene. However, previous methods used “dirty” materials in their charge-transfer layers; impurities in these would leave the graphene unevenly doped and impede its ability to conduct electricity.

Two drugs approved decades ago not only counteract brain damage caused by Alzheimer’s disease in animal models, the same therapeutic combination may also improve cognition.

Sounds like a slam dunk in terms of a cure—but not yet. Researchers currently are concentrating on animal studies amid implications that remain explosive: If a surprising drug combination continues to destroy a key feature of the disease, then an effective treatment for Alzheimer’s may have been hiding for decades in plain sight.

A promising series of early studies is highlighting two well known medicine cabinet standbys—gemfibrosil, an old-school cholesterol-lowering drug, and retinoic acid, a vitamin A derivative. Gemfibrosil, is sold as Lopid and while it’s still used, it is not widely prescribed. Doctors now prefer to prescribe statins to lower cholesterol. Retinoic acid has been used in various formulations to treat everything from acne to psoriasis to cancer.

Researchers have identified a potential new treatment that suppresses the replication of SARS-CoV-2, the coronavirus that causes Covid-19.

In order to multiply, all viruses, including coronaviruses, infect cells and reprogramme them to produce novel viruses.

The research revealed that cells infected with SARS-CoV-2 can only produce novel coronaviruses when their metabolic pentose phosphate pathway is activated.
