An artificial intelligence algorithm can learn the laws of quantum mechanics

Posted by in categories: chemistry, information science, quantum physics, robotics/AI

Artificial intelligence can be used to predict molecular wave functions and the electronic properties of molecules. This innovative AI method developed by a team of researchers at the University of Warwick, the Technical University of Berlin and the University of Luxembourg, could be used to speed-up the design of drug molecules or new materials.

Artificial intelligence and are routinely used to predict our purchasing behavior and to recognize our faces or handwriting. In , Artificial Intelligence is establishing itself as a crucial tool for scientific discovery.

In chemistry, AI has become instrumental in predicting the outcomes of experiments or simulations of quantum systems. To achieve this, AI needs to be able to systematically incorporate the fundamental laws of .

Fuel cell drone makes an epic ocean crossing

Posted by in categories: biotech/medical, drones

Although multicopter drones now are being used to transport medical samples and supplies, their 30-minute (or so) battery life limits their range. This week, however, a hydrogen-powered delivery drone managed a one-hour, 43-minute ocean crossing.

The exercise was the result of a collaboration between Texas-based drone development company Guinn Partners, Georgia-based Skyfire Consulting, the US Department of Health, and drone manufacturer Doosan Mobility Innovation – the latter supplied the aircraft, a hydrogen fuel cell-powered DS30 octocopter.

Utilizing its temperature-controlled payload system, the drone was used to transport live bacteria samples from a hospital on the Caribbean island of St. Croix to a testing facility on the neighboring island of St. Thomas. This involved crossing 43 miles (69 km) of open ocean. Upon successfully reaching its destination, the copter reportedly still had almost 30 minutes of flight time left on its fuel cell.

Life-long epigenetic programming of cortical architecture

Posted by in categories: biotech/medical, evolution, food, genetics, life extension, neuroscience

The evolution of human diets led to preferences toward polyunsaturated fatty acid (PUFA) content with ‘Western’ diets enriched in ω-6 PUFAs. Mounting evidence points to ω-6 PUFA excess limiting metabolic and cognitive processes that define longevity in humans. When chosen during pregnancy, ω-6 PUFA-enriched ‘Western’ diets can reprogram maternal bodily metabolism with maternal nutrient supply precipitating the body-wide imprinting of molecular and cellular adaptations at the level of long-range intercellular signaling networks in the unborn fetus. Even though unfavorable neurological outcomes are amongst the most common complications of intrauterine ω-6 PUFA excess, cellular underpinnings of life-long modifications to brain architecture remain unknown. Here, we show that nutritional ω-6 PUFA-derived endocannabinoids desensitize CB1 cannabinoid receptors, thus inducing epigenetic repression of transcriptional regulatory networks controlling neuronal differentiation. We found that cortical neurons lose their positional identity and axonal selectivity when mouse fetuses are exposed to excess ω-6 PUFAs in utero. Conversion of ω-6 PUFAs into endocannabinoids disrupted the temporal precision of signaling at neuronal CB1 cannabinoid receptors, chiefly deregulating Stat3-dependent transcriptional cascades otherwise required to execute neuronal differentiation programs. Global proteomics identified the immunoglobulin family of cell adhesion molecules (IgCAMs) as direct substrates, with DNA methylation and chromatin accessibility profiling uncovering epigenetic reprogramming at 1400 sites in neurons after prolonged cannabinoid exposure. We found anxiety and depression-like behavioral traits to manifest in adult offspring, which is consistent with genetic models of reduced IgCAM expression, to suggest causality for cortical wiring defects. Overall, our data uncover a regulatory mechanism whose disruption by maternal food choices could limit an offspring’s brain function for life.

Study Finds Limited Benefits of Stent Use for Millions With Heart Disease

Posted by in categories: biotech/medical, health

PHILADELPHIA—Stents and coronary artery bypass surgery are no more effective than intensive drug treatment and better health habits in preventing millions of Americans from heart attacks and death, a large study found, shedding new light on a major controversy in cardiology.

Researchers and doctors have fiercely debated for years how best to treat people who have narrowed coronary arteries but aren’t suffering acute symptoms.

    To Live Longer, Start Running Now, Even Just A Little Bit

    Posted by in category: health

    It may be possible to out-run death, at least for a little while, according to a recent study.

    An international team of researchers analyzed data from 14 previous studies involving a total of 232,149 people who had their health tracked by scientists for at least five years and as long as 35 years. They found that, of the 25,951 individuals who died during this period, those who ran were correlated with a 27 percent lower risk of death than those who didn’t run at all.

    The association was found among both men and women and even when a person went for just one slow jog a week or even less.

    U.S. Space Command eager to hand over space traffic duties to Commerce Department

    Posted by in categories: military, satellites

    WASHINGTON — Military space operators at Vandenberg Air Force Base, California, are working with the Department of Commerce to help ease the transfer of space traffic management responsibilities, Maj. Gen. Stephen Whiting said Nov. 15.

    “We’re eager for that to happen,” Whiting said at a Mitchell Institute event on Capitol Hill.

    Whiting is the commander of the 14th Air Force and the Combined Force Space Component Command under U.S. Space Command. He oversees the two major organizations — the Combined Space Operations Center and the 18th Space Control Squadron — that help to maintain a catalog of space objects and notify satellite operators around the world when other satellites or debris threaten to collide with spacecraft.

    Grub granola? How we’ll all be eating insect-based foods in a decade

    Posted by in categories: food, sustainability

    Insect farming is a small – but growing – industry globally, with bugs touted as a sustainable and cheap food that is high in protein, vitamins, fibre and minerals. Their cultivation, meanwhile, has much less environmental impact than meat.

    With predictions that the insect market could grow significantly, it is not just scientists cooking up ways to put bugs on the menu but also some of the world’s largest food and agricultural companies.
