System uses machine learning to offer new way to screen for hard to detect cancers

Scientists say that a discovery in a seaside Portuguese cave further challenges popular images of Neanderthals as meat-eating brutes.

It’s been several decades since NASA’s Voyager 2 spacecraft reached the chilly planet Uranus. The probe cruised past the frigid world at a distance of around 50,000 miles, sending back a wealth of data for scientists to dig through. Now, 34 years after it visited Uranus, the data that Voyager 2 sent back has revealed something entirely new.

As the last Ice Age tightened its hold on Europe, a group of people living near the Don River piled dozens of mammoth bones into a 12.5m (30ft) wide circle. They may have lived in the shelter of the mammoth bones for a while, huddling around fragrant fires of conifer wood and mammoth bone and making stone tools. But the traces they left are so light that it seems they didn’t stay long—or maybe they only visited occasionally.

This is a profound discussion,do watch.

Some cellular proteins move across a cell’s membrane in rippling waves, displaying patterns of turbulence that resemble those seen throughout the physical world. When bound to a cell membrane, the signalling protein Rho-GTP plays a part in the multistep process that leads a cell to divide. Proteins similar to Rho-GTP are found in a vast number of organisms, including vertebrates.

Natural evolution did not create a chicken that lays so many unfertilized eggs. Human engineering created such chickens. You could call the process...

A bacterium that feeds on toxic plastic has been discovered by scientists. The bug not only breaks the plastic down but uses it as food to power the process. The bacterium, which was found at a waste site where plastic had been dumped, is the first that is known to attack polyurethane. Millions of tonnes of the plastic is produced every year to use in items such as sports shoes, nappies, kitchen sponges and as foam insulation, but it is mostly sent to landfill because it it too tough to recycle.

Like humans, it had a butt, a head and two symmetrical sides. It's practically family.

SARS-CoV-2, the cause of the pandemic, belongs to one of 6,828 named species of virus. Hundreds of thousands more species are known, with perhaps trillions waiting to be found.

Many basic and clinical researchers are testing the potential of a simple and efficient gene editing approach to study and correct disease-causing mutations for conditions ranging from blindness to cancer, but the technology is constrained by a requirement that a certain short DNA sequence be present at the gene editing site.

Terrifying though the coronavirus may be, it can be turned back. China, South Korea, Singapore and Taiwan have demonstrated that, with furious efforts, the contagion can be brought to heel. Whether they can keep it suppressed remains to be seen. But for the United States to repeat their successes will take extraordinary levels of coordination and money from the country’s leaders, and extraordinary levels of trust and cooperation from citizens. It will also require international partnerships in an interconnected world. There is a chance to stop the coronavirus. This contagion has a weakness.

"If you feel unconfident, I can change that. Sometimes one or two inches makes a world of difference."

Professor Dame Sally Davies, England’s chief medical officer is sounding the alarm on antibiotic resistance, claiming it could kill ten million people per year, effectively wiping out humanity. Plastic pollution and antibiotic use in animal agriculture could be to blame. But what is antibiotic resistance and what role does meat play in it?

Yale researchers’ discovery of a key molecule in the brain could lead to potential treatments for neurocognitive disorders like schizophrenia and Alzheimer’s.

In a new study, scientists uncovered the deepest roots of bias in the brain.

NASA has made the decision to send all of its staff in centers across the country home amid the coronavirus pandemic. The decision comes in the wake of multiple NASA facilities being forced into mandatory work-from-home status after staff members tested positive for COVID-19.

New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth's axis was approaching higher values.

Take chemistry, add energy, get life. The first tests of Jeremy England’s provocative origin-of-life hypothesis are in, and they appear to show how order can arise from nothing.
