Rearing virus-resistant birds could benefit humans too, say scientists, and Covid may have made us more open to the controversial technology

The Covid-19 pandemic has revived a debate over public health and individual liberty that goes back to colonial times.

The first-in-human clinical trial for a candidate treatment for individuals living with human immunodeficiency virus type 1 is starting soon after its maker, Excision BioTherapeutics, today received an Investigational New Drug clearance from the U.S. Food and Drug Administration (FDA).

What runs through your mind when you’re deciding which toilet paper to buy? Sale price, roll size, pitiful single-ply or luxurious triple? Climate change might not make your list of considerations, but it should: According to the Natural Resources Defense Council, the toilet paper industry is among the most egregious climate offenders in Canada.

Pioneering research shows that dopamine levels increase in response to stressful stimuli, and not just pleasurable ones, potentially rewriting facts about the “feel-good” hormone—a critical mediator of many psychiatric diseases. This discovery is cause to rethink treatment for psychiatric disease and addiction.

The whitest paint in the world has been created in a lab at Purdue University, a paint so white that it could eventually reduce or even eliminate the need for air conditioning, scientists say. The paint has now made it into the Guinness World Records book as the whitest ever made.

The DNA of some viruses doesn’t use the same four nucleotide bases found in all other life. New work shows how this exception is possible and hints that it could be more common than we think.

A new study, led by researchers at the University of Cambridge and reported in the journal Physical Review D, suggests that some unexplained results from the XENON1T experiment in Italy may have been caused by dark energy, and not the dark matter the experiment was designed to detect.

Ten thousand years after woolly mammoths vanished from the face of the Earth, scientists are embarking on an ambitious project to bring the beasts back to the Arctic tundra. The prospect of recreating mammoths and returning them to the wild has been discussed – seriously at times – for more than a decade, but on Monday researchers announced fresh funding they believe could make their dream a reality.

Paleoanthropologists have sketched a rough timeline of how human evolution played out, centering the early action in Africa.

A 900-year-old cosmic mystery surrounding the origins of a famous supernova first spotted over China in 1181AD has finally been solved, according to an international team of astronomers.

With $15 million in private funding, Colossal aims to bring thousands of woolly mammoths back to Siberia. Some scientists are deeply skeptical that will happen.

The cancer protein that indicates which tumors are ‘on’ could lead to therapies to keep them ‘off’ forever. A team of scientists from the Lunenfeld-Tanenbaum Research Institute in Canada found a specific protein that turns on cancer in the human body. It is not limited to a specific type of cancerous condition but appears to be common to all variants seen by medicine thus far

A new Yale-led study finds that immune system activity jump-started by rhinovirus exposure could prevent or treat the early stages of COVID-19 infection.

Scientists discover how snakes survived and diversified after the extinction event that killed off the majority of species on Earth, including dinosaurs.

MIT engineers developed a way to grow tiny replicas of the pancreas, using either healthy or cancerous pancreatic cells. Their models could help researchers develop and test potential drugs for pancreatic cancer.

A spectroscopic liquid biopsy technique can detect both small and low-grade brain tumours

Try as we might, the most advanced synthetic materials pale in comparison to super-strong biological compounds like spider silk and muscle fibers. On that second count, researchers may be closer to growing usable amounts of muscle fiber that can be used in place of fabrics like cotton, silk, and even Kevlar. This could lead to clothing made from real muscle. That might sound like an unsettling option, but the fibers aren’t what you’re imagining.

It was a member of a small, isolated community of mammoths that was the last vestige of a once-thriving species that could be found roaming the plains of the northern hemisphere from Alaska to Siberia. Scientists still debate what caused the mammoths to finally go extinct, but the general consensus is that it was a combination of human hunting, genetic defects from inbreeding, and natural climate change, which shrank suitable mammoth habitat by a factor of ten.

Transporting a single brick to Mars can cost more than a million British pounds – making the future construction of a Martian colony seem prohibitively expensive. Scientists at The University of Manchester have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along with the blood, sweat and tears of astronauts.
