Whale sharks show remarkable capacity to recover from injuries, including partial fin re-growing

|

A new study has for the first time explored the rate at which the world’s largest fish, the endangered whale shark, can recover from its injuries. The findings reveal that lacerations and abrasions, increasingly caused through collisions with boats, can … Read More

‘Walking’ molecule superstructures could help create neurons for regenerative medicine: 3D-printed novel biomaterial mimics properties of living tissues

|

Imagine if surgeons could transplant healthy neurons into patients living with neurodegenerative diseases or brain and spinal cord injuries. And imagine if they could “grow” these neurons in the laboratory from a patient’s own cells using a synthetic, highly bioactive … Read More

The Milky Way may be swarming with planets with oceans and continents like here on Earth

|

Astronomers have long been looking into the vast universe in hopes of discovering alien civilisations. But for a planet to have life, liquid water must be present. The chances of that finding scenario have seemed impossible to calculate because it … Read More

NASA’s Mars Perseverance rover provides front-row seat to landing, first audio recording of Red Planet

|

New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of … Read More

Sleep is vital to associating emotion with memory, study finds

|

When you slip into sleep, it’s easy to imagine that your brain shuts down, but University of Michigan research suggests that groups of neurons activated during prior learning keep humming, tattooing memories into your brain. U-M researchers have been studying … Read More

Air pollution puts children at higher risk of disease in adulthood

|

Children exposed to air pollution, such as wildfire smoke and car exhaust, for as little as one day may be doomed to higher rates of heart disease and other ailments in adulthood, according to a new Stanford-led study. The analysis, … Read More

Potentially harmful chemicals found in plastic toys

|

It has long been known that several chemicals used in plastic toys in different parts of the world can be harmful to human health. However, it is difficult for parents to figure out how to avoid plastic toys containing chemicals … Read More

‘Jumping genes’ repeatedly form new genes over evolution

|

In the same way that Lego pieces can be arranged in new ways to build a variety of structures, genetic elements can be mixed and matched to create new genes, according to new research. A long-proposed mechanism for creating genes, … Read More

A speed limit also applies in the quantum world: Study determines minimum time for complex quantum operations

|

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved … Read More

Touchdown! NASA’s Mars Perseverance Rover safely lands on Red Planet

|

The largest, most advanced rover NASA has sent to another world touched down on Mars Thursday, after a 203-day journey traversing 293 million miles (472 million kilometers). Confirmation of the successful touchdown was announced in mission control at NASA’s Jet … Read More

Scientists identify more than 140,000 virus species in the human gut: Study opens up new research avenues for understanding how viruses living in the gut affect human health

|

Viruses are the most numerous biological entities on the planet. Now researchers at the Wellcome Sanger Institute and EMBL’s European Bioinformatics Institute (EMBL-EBI) have identified over 140,000 viral species living in the human gut, more than half of which have … Read More

New crystalline form of ice: Scientists elucidate crystal structure for exotic ice XIX

|

Three years ago, chemists found evidence for the existence of a new variety of ice. Until then, 18 types of crystalline ice were known. The team now reports on the elucidation of the crystal structure of ice XIX using neutron … Read More

Neandertal gene variants both increase and decrease the risk for severe COVID-19

|

Last year, researchers at Karolinska Institutet in Sweden and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany showed that a major genetic risk factor for severe COVID-19 is inherited from Neandertals. Now the same researchers show, in a … Read More

Climate change likely drove the extinction of North America’s largest animals

|

A new study published in Nature Communications suggests that the extinction of North America’s largest mammals was not driven by overhunting by rapidly expanding human populations following their entrance into the Americas. Instead, the findings, based on a new statistical … Read More

New theory explains possible origin of plummeting Chicxulub impactor that struck off Mexico

|

It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, left behind a crater off the coast of Mexico that spans 93 miles and … Read More

Brain imaging reveals that not all monogamous mammals are ‘wired for love’ in the same way

|

Humans aren’t the only mammals that form long-term bonds with a single, special mate — some bats, wolves, beavers, foxes and other animals do, too. But new research suggests the brain circuitry that makes love last in some species may … Read More
