Did teenage ‘tyrants’ outcompete other dinosaurs? Researchers examine how carnivorous dinosaur offspring reduced species diversity

|

Paleo-ecologists from The University of New Mexico and at the University of Nebraska-Lincoln have demonstrated that the offspring of enormous carnivorous dinosaurs, such as Tyrannosaurus rex may have fundamentally re-shaped their communities by out-competing smaller rival species. The study, released … Read More

People with SARS-CoV-2 antibodies may have low risk of future infection, study finds

|

People who have had evidence of a prior infection with SARS-CoV-2, the virus that causes COVID-19, appear to be well protected against being reinfected with the virus, at least for a few months, according to a newly published study from … Read More

New study suggests supermassive black holes could form from dark matter

|

A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team find that rather than the conventional formation scenarios involving ‘normal’ matter, supermassive black holes could instead form directly … Read More

How did dogs get to the Americas? An ancient bone fragment holds clues

|

The history of dogs has been intertwined, since ancient times, with that of the humans who domesticated them. But how far back does that history go in the Americas, and which route did dogs use to enter this part of … Read More

A memory without a brain: How a single cell slime mold makes smart decisions without a central nervous system

|

Having a memory of past events enables us to take smarter decisions about the future. Researchers at the Max-Planck Institute for Dynamics and Self-Organization (MPI-DS) and the Technical University of Munich (TUM) have now identified how the slime mold Physarum … Read More

The way a fish swims reveals a lot about its personality, say scientists

|

Personality has been described in all sorts of animal species, from ants to apes. Some individuals are shy and sedentary, while others are bold and active. Now a new study published in Ecology and Evolution has revealed that the way … Read More

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
