A new study is the first to quantify the proportion of differences in sensitivity that can be explained by genetic factors.
Warrior: The Army must have some major efforts looking at what war may look like in 20 to 30 years?
Murray: “We have something called ‘Team Ignite.’ It is not a standing organization but a cross-functional team between my technologists and my scientists. One part is responsible for the technology at Combat Capabilities Development Command, another is a ‘future concepts’ unit at Fort Eustis, Va. and my concept writers at our Futures and Concepts Center. This forces the people who are thinking about future concepts to take technology into account because they technologists are right there with them. This forces them to think about how technology will change the concept… also it directly feeds what we should be investing in our science and technology areas.”
Gen. John Murray, commander of Army Futures Command, explains what future wars will look like.

It’s no surprise that Tesla’s next-gen Roadster is going to be lightning-quick, with a claimed 0–60 mph time of 1.9 seconds for the base model. However, the addition of SpaceX cold-gas thrusters that will be hidden behind the car’s license plate could drop Roadster’s 0–60 mph time to a dizzying 1.1 seconds.
YouTube channel Engineering Explained used some of Isaac Newton’s basic physics principles to determine that the Roadster could become one of the quickest cars in the world. By plugging in existing information that CEO Elon Musk has revealed about Tesla’s next-gen Roadster, host Jason Fenske determined that the vehicle will weigh roughly 2000 kg (4,400 lbs), which backs into acceleration g-forces of approximately 1.44 G’s.

Move over, graphene — you’re not the only miracle material in town. Australian researchers have discovered that diamond nanothreads (one-dimensional diamond crystals capped with hydrogen) could be extremely strong. While scientists thought they were brittle when announced just a month ago, it turns out that they become supremely flexible (and thus durable) when you introduce the right kinds of defects. You could create nanoscopic structures that are just as strong as you need them to be, with a ‘perfect’ mix of bendy and rigid shapes.
The immersive qualities of virtual-reality gaming are making effective biofeedback treatment of anxiety and other conditions more affordable and accessible.
Two people with beta thalassaemia and one with sickle cell disease no longer require blood transfusions, which are normally used to treat severe forms of these inherited diseases, after their bone marrow stem cells were gene-edited with CRISPR.
Result of the ongoing trial, which is the first to use CRISPR to treat inherited genetic disorders, were announced today at a virtual meeting of the European Hematology Association.
This is really old news:
Two tried-and-true vaccines — a century-old inoculation against tuberculosis and a decades-old polio vaccine once given as a sugar cube — are being evaluated to see if they can offer limited protection against the coronavirus.
The old vaccines are oddities among the cutting-edge and targeted technologies being developed to combat the novel coronavirus. New vaccines aim to teach the body’s immune system to recognize and destroy the coronavirus, but scientists are only now beginning to test them in people. Vaccines developed against TB and polio have already been used in millions of people and could offer a low-risk way to rev up the body’s first line of defense — the innate immune system — against a broad array of pathogens, including the coronavirus.

Chinese company, Contemporary Amperex Technology Co. Ltd. (CATL), this week announced a new battery technology that could revolutionise the electric vehicle market.
Established in 2011 and headquartered in Ningde, eastern China, CATL employs more than 24,000 people and has grown to become the world’s largest maker of lithium batteries. Amid surging demand for electric vehicles, its revenue soared by 54% last year. China, as a whole, installed 62.2 GWh of battery storage capacity last year, according to the China Automotive Battery Industry Innovation Alliance, of which CATL supplied 31.5 GWh for a market share of nearly 51%.
In addition to domestic sales, CATL supplies a wide range of carmakers internationally – including Tesla, BMW, Toyota, Honda, and Volkswagen. While sales have slumped more recently, due to the COVID-19 pandemic, CATL and its clients are expecting demand to return in 2021.
Rational design of compounds with specific properties requires understanding and fast evaluation of molecular properties throughout chemical compound space — the huge set of all potentially stable molecules. Recent advances in combining quantum-mechanical calculations with machine learning provide powerful tools for exploring wide swathes of chemical compound space. We present our perspective on this exciting and quickly developing field by discussing key advances in the development and applications of quantum-mechanics-based machine-learning methods to diverse compounds and properties, and outlining the challenges ahead. We argue that significant progress in the exploration and understanding of chemical compound space can be made through a systematic combination of rigorous physical theories, comprehensive synthetic data sets of microscopic and macroscopic properties, and modern machine-learning methods that account for physical and chemical knowledge.
An international collaboration of scientists has recorded the most accurate confirmation to date for one of the cornerstones of Einstein’s theory of general relativity, ‘the universality of free fall.’
The new research shows that the theory holds for strongly self-gravitating objects such as neutron stars. Using a radio telescope, scientists can very accurately observe the signal produced by pulsars, a type of neutron star and test the validity of Einstein’s theory of gravity for these extreme objects. In particular, the team analyzed the signals from a pulsar named ‘PSR J0337+1715’ recorded by the large radio telescope of Nançay, located in the heart of Sologne (France).
The universality of free fall principle states that two bodies dropped in a gravitational field undergo the very same acceleration independently of their composition. This was first demonstrated by Galileo who famously would have dropped objects of different masses from the top of Pisa’s tower to verify that they both reach the ground simultaneously.
