For years, scientists have been attempting to replicate in silicon the functions of neurons – the nerve cells that are the fundamental units of the human brain. Now researchers at the University of Bath claim to have done it. The achievement rests on three breakthroughs, the developers say: they developed a mathematical method to model...

RAPALOG DRUGS MAY EXTEND HEALTHY LIFE
Two recent trials indicate that the family of rapalog drugs may extend humans’ healthy lifespan. The family’s best-known member is rapamycin, which is used in organ transplants to suppress rejection. In studies, rapalogs have shown an ability to extend the health spans of yeast, worms, flies, and mice by as much as 20 percent. That...
NEW SUPERCAPACITOR COULD REPLACE BATTERIES
In today’s lithium batteries, the problem is cobalt. It’s necessary to stabilize lithium, boost the amount of energy a battery can store, and extend a battery’s life. But mining it is damaging to human health and Mother Nature, soaring demand for lithium batteries threatens a cobalt shortage, and most of the world’s deposits are in...
PETROPLASTICS OUT, PECTIN PLASTICS IN
The world may be turning away from petroleum as a vehicle fuel, but humans still use almost 600 billion plastic bottles made from petroleum each year. A small fraction is recycled into new materials; the vast majority are trashed and clog our oceans, waterways, garbage dumps, and roadsides, where their breakdown residues enter the food...
DO WINE & CHEESE PROTECT AGAINST COGNITIVE DECLINE?
First, medical science discovered that dark chocolate is a superfood and sex is a better aerobic exercise than jogging. Now bioscientists at Iowa State University have found that wine and cheese may protect against dementia. The researchers sifted data from the UK Biobank, a database holding extensive genetic and health details on more than a...
HARVESTING SOLAR POWER FROM SPACE TAKES KEY STEP FORWARD
Gathering solar energy above the clouds and sending it back to Earth has been on scientists’ minds for decades. Now the plan has taken a large step toward reality. The idea is to send high-efficiency solar collectors into space, have them convert the solar energy they make into radio waves, then beam the energy waves...
MELATONIN IDENTIFIED AS PROBABLE COVID TREATMENT
Melatonin, the body’s own hormone that regulates sleeping and waking, has been identified as a potential treatment for the COVID virus in a study by the Cleveland Clinic. The study used artificial intelligence to comb through the catalog of existing biochemical substances to see which might be used to neutralize SARS-CoV-2, the virus that causes...
NEW BATTERY COULD DOUBLE EV RANGE, SLASH CHARGING TIMES
Volkswagen has invested $300 million in QuantumScape, a quiet California company that has invented a new lithium-metal battery that could provide the convenience missing from today’s electric vehicles. According to QuantumScape’s test results, the flat battery can charge to 80 percent of capacity in 15 minutes (Tesla’s charged to 90 percent in 37 minutes in...
CHEAP, EASY WAY TO SOLIDIFY NATURAL GAS
Gas-rich countries, such as the U.S., see a growing world market for their resource. But exporting natural gas means investing in multi-billion-dollar ports where the stuff can be cooled and stored at around -260°F, then pumped aboard refrigerator tankers to sail off to foreign lands. Even storing natural gas in your home’s tank for cooking...
COMPUTER COMPLETES BILLION-YEAR TASK IN 3 MIN
If you’ve ever wondered how fast a quantum computer really is, scientists at the University of Science and Technology of China can tell you: fast enough to complete in three minutes a calculation that would take today’s fourth-best supercomputer an estimated 200 billion years to solve. Conventional computers process information, moving as an electrical current,...
