UN treaty banning nuclear weapons set to enter into force in January

Posted by in categories: geopolitics, military, nuclear weapons, treaties

In what leading campaigners are describing as “a new chapter for nuclear disarmament”, the ratification of the Treaty on the Prohibition of Nuclear Weapons will now come into force on 22 January, after Honduras became the 50th Member State to ratify on Saturday.

Melding biology and physical sciences yields deeper understanding of cancer

Posted by in categories: biotech/medical, genetics

In a review published in the journal *Science*, Jain and Steele Laboratories colleagues Hadi T. Nia, PhD, and Lance L. Munn, PhD, describe four distinct physical hallmarks of cancer that affect both cancer cells and the tumor microenvironment, contributing to both tumor growth and the development of resistance to powerful cancer drugs.

One widely accepted model of cancer holds that a normal cell goes rogue because of genetic mutations or an environmental insult. In this model, the altered cell starts replicating out of control and takes over normal tissues, displaying eight hallmarks that include the ability to promote and sustain the growth of tumors, evade immune system attempts to suppress growth, stimulate blood flow to tumors and both invade local tissues and metastasize (spread) elsewhere in the body.

But this model fails to take into account how physical processes affect tumor progression and treatment, say the authors. In addition to the aforementioned eight biological hallmarks of cancer proposed by Robert Weinberg, PhD, from MIT, and Douglas Hanahan, PhD, from the Swiss Federal Institute of Technology in Lausanne, Jain and colleagues propose adding four distinct physical hallmarks that capture the biomechanical abnormalities in tumors: elevated solid stress; elevated interstitial fluid pressure; increased stiffness and altered material properties; and altered tissue micro-architecture.

Laundry Filter Saves The Ocean From Microplastics

Posted by in category: futurism

Video from Waste-Ed. So basically, when we wash our clothes we release microplastics into the environment. The plastics come from fibers in our clothes.

They’ve added a filter to the washing machine to collect these microplastics to prevent these from spreading.

Dirt isn’t the only thing getting washed down the drain when you do laundry! Before your clothes make it to the dryer, tiny microfibers break off in the wash and travel through wastewater to pollute our… More environment. That changes with this microplastics filter that stops pollution at the source! Just install it on the side of the washer and send it back for safe disposal after it’s full. It captures 90% of the fibers that contaminate our planet!

Tesla Autopilot Would Avoid 90% of Car Accidents, German Researcher Urges Country’s Adoption

Posted by in categories: law, robotics/AI, transportation

R-sharing. Hmmm… would you trust the AI to drive for you?

At the end of November, Tesla (NASDAQ: TSLA) released its Vehicle Safety Report for Q3 2020, which shows that its vehicles using Autopilot are almost 10 times safer than other vehicles on United States roads. While the California manufacturer has directed massive efforts towards achieving Level 5 autonomy, the development of autonomous driving in Europe is at best slow-moving.

Recently, though, researchers in Germany are suggesting that this should change, and for good reason. The researchers indicate that, if Tesla Autopilot were installed on all cars in the Germany now, they would be able to avoid hundreds of thousands of car accidents.

How To Build Your Own Chatbot Using Deep Learning

Posted by in category: robotics/AI

If you are interested in developing chatbots, you can find out that there are a lot of powerful bot development frameworks, tools, and platforms that can use to implement intelligent chatbot solutions. How about developing a simple, intelligent chatbot from scratch using deep learning rather than using any bot development framework or any other platform. In this tutorial, you can learn how to develop an end-to-end domain-specific intelligent chatbot solution using deep learning with Keras.

How Coronavirus Can Be Stopped: 3D Atomic Map of COVID-19’s Viral Replication Mechanism

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

To better understand how the novel coronavirus behaves and how it can be stopped, scientists have completed a three-dimensional map that reveals the location of every atom in an enzyme molecule critical to SARS-CoV-2 reproduction.

Researchers at the Department of Energy’s Oak Ridge National Laboratory used neutron scattering to identify key information to improve the effectiveness of drug inhibitors designed to block the virus’s replication mechanism. The research is published in the Journal of Biological Chemistry.

The SARS-CoV-2 virus, which causes the COVID-19 disease, expresses long chains of proteins composed of approximately 1,900 amino acid residues. For the virus to reproduce, those chains have to be broken down and cut into smaller strands by an enzyme called the main protease. The active protease enzyme is formed from two identical protein molecules held together by hydrogen bonds. Developing a drug that inhibits or blocks the protease activity will prevent the virus from replicating and spreading to other cells in the body.

Are the Brain’s Electromagnetic Fields the Seat of Consciousness?

Posted by in category: neuroscience

“It was a jaw-dropping moment, for us and for every scientist we told about this so far.”

But what if there’s more to the story? What if the electromagnetic fields generated by, but which are not identical to, the neuroanatomy of the brain, are in fact the primary seat of consciousness? The brain’s fields are generated by various physiological processes in the brain, but primarily by trans-membrane currents moving through neurons. These fields are always oscillating and they come in various speeds, clustered around certain bands, from delta on the lower end at 1–2.5 cycles (oscillations) per second (Hertz) up to gamma at 40–120 cycles per second.

Some neuroscientists have long considered the brain’s oscillating electromagnetic fields to be interesting but merely “epiphenomenal” features of the brain—like a train whistle on a steam-powered locomotive. Electromagnetic fields may just be noise that doesn’t affect the workings of the brain. Koch still seems to lean this way.

3D-printing “error” used to produce high-tech textiles

Posted by in category: materials

If a 3D printer leaves gaps in the plastic that it deposits, it’s usually thought of as an unwanted flaw. Now, however, the process has been harnessed to quickly and cheaply produce pliable polymer textiles.

Ordinarily, commonly used fused deposition modelling (FDM)-type printers create items by extruding successive layers of molten plastic. Once the layers of deposited plastic have cooled and fused together, they form a hardened solid object.

Sometimes, though – due to a flaw in the printer or the programming – not enough plastic is extruded. This is known as under-extrusion, and it results in the finished product being full of small gaps.
