Biosignature on Venus likely to be mistake, says new study

Back in September last year, astronomers made a splash when they announced the discovery of phosphine in the atmosphere of Venus, which could be a sign of life. But a new study has found that a different gas could explain the signature detected, and th… Continue reading Biosignature on Venus likely to be mistake, says new study

Alzheimer’s brain tissue study uncovers three distinct disease subtypes

Researchers analyzed more than 1,500 postmortem brain tissue samples to distinguish the molecular differences between various cases of Alzheimer's disease

Despite decades of rigorous research, scientists are still struggling to crack the mystery of Alzheimer’s disease. Promising preclinical research has consistently led to frustrating clinical trial failures and some have started to question whether we are even targeting the correct pathological mechanisms.

Synthetic molecules mimic human cells to lure and kill the flu virus

The influenza virus as proven to be a very tricky foe to fight. Now, researchers at EPFL in Switzerland have developed synthetic molecules that can kill the flu virus by mimicking human cells, and putting the squeeze on the virus when it attaches itsel… Continue reading Synthetic molecules mimic human cells to lure and kill the flu virus

Weird molecule found in Titan’s atmosphere hints at complex chemistry

NASA scientists have discovered a “weird” molecule called cyclopropenylidene, or C3H2, in the atmosphere of Saturn’s moon Titan. The simple carbon-based molecule has never been seen in an atmosphere before, and it could give rise to more complex compou… Continue reading Weird molecule found in Titan’s atmosphere hints at complex chemistry

Synthetic molecules repair mouse brain function lost to disease and injury

Newly created synthetic molecules could help repair brain connections lost to disease or injury

The brain is an incredibly complex network of connections, but in some neurological disorders those connections can be lost. Researchers from the UK, Germany and Japan have now created synthetic molecules that may be able to help patch them up, with tests in cultured cells and mice showing promise in treating disease and injury.

Antivitamins breakthrough could make for antibiotics alternative

Antibiotics are one of the most important medical breakthroughs of all time – but their usefulness is beginning to unravel, with potentially devastating results. In the hunt for new drugs, researchers have now investigated how an antivitamin of Vitamin… Continue reading Antivitamins breakthrough could make for antibiotics alternative

Seasonal ultraviolet light pulses in Martian skies three times a night

A NASA spacecraft has observed a pulsing glow coming from Mars. Huge spots of ultraviolet light were seen in the night sky, pulsing with uncanny regularity – exactly three times every night. The find highlights (literally) the atmospheric processes and… Continue reading Seasonal ultraviolet light pulses in Martian skies three times a night

New blood thinner prevents clots with less risk of excess bleeding

We need our blood to walk a very fine line between flowing freely and clotting, and treatments for blood clots in the body naturally come with a risk of excessive bleeding from an injury. But now, researchers at EPFL have developed a synthetic blood th… Continue reading New blood thinner prevents clots with less risk of excess bleeding

“Filler” ingredients in drugs more biologically active than assumed

New research has systematically screened thousands of “filler” ingredients previously thought to be inert that are added to common drugs. The findings reveal several dozen of these compounds may actually be biologically active and cause unintended phys… Continue reading “Filler” ingredients in drugs more biologically active than assumed

Nano-motor of just 16 atoms runs at the boundary of quantum physics

Researchers at Empa and EPFL have created one of the smallest motors ever made. It’s composed of just 16 atoms, and at that tiny size it seems to function right on the boundary between classical physics and the spooky quantum realm.Continue ReadingCate… Continue reading Nano-motor of just 16 atoms runs at the boundary of quantum physics
