Non-cognitive skills: DNA-based analyses suggest a hidden key to academic success

A new Nature Human Behaviour study, jointly led by Dr. Margherita Malanchini at Queen Mary University of London and Dr. Andrea Allegrini at University College London, has revealed that non-cognitive skills, such as motivation and self-regulation, are as important as intelligence in determining academic success. These skills become increasingly influential throughout a child's education, with genetic factors playing a significant role.

One of Colorado's reintroduced wolves wandered into Rocky Mountain National Park

One of Colorado's reintroduced wolves wandered into Rocky Mountain National Park this month, marking the first time one has been present in the park since the state released wolves in December.

Finding love: Study reveals where love lives in the brain

We use the word "love" in a bewildering range of contexts—from sexual adoration to parental love or the love of nature. Now, more comprehensive imaging of the brain may shed light on why we use the same word for such a diverse collection of human experiences.

Antidepressant pollution is rewiring fish behavior and reproduction, biologists reveal

An international study led by biologists from Monash University and the University of Tuscia has revealed how long-term exposure to pharmaceutical pollutants is dramatically altering fish behavior, life history, and reproductive traits.

Archaeologists discover diseased Anglo-Saxons that received monastic care

An additional 20 intact human burials and the disturbed remains of many more have been discovered by archaeologists excavating a monastery in Cookham.

Paper types ranked by likelihood of paper cuts

Via testing with a skin stand-in, a trio of physicists at Technical University of Denmark has ranked the types of paper that are the most likely to cause a paper cut. In an article published in Physical Review E, Sif Fink Arnbjerg-Nielsen, Matthew Biviano and Kaare Jensen tested the cutting ability and circumstances involved in paper cuts to compile their rankings.

Scientists discover a long-sought global electric field on Earth

Using observations from a NASA suborbital rocket, an international team of scientists, for the first time, has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields.

Rare whale species observed during recent Antarctic expedition

Research by Wageningen Marine Research and partners on the relationship between sea ice and the Southern Ocean food web investigates various components of that food web, including the so-called "top predators," or seabirds and marine mammals. To map their numbers and distribution, observers count these animals during Antarctic expeditions. During the latest expedition, on board the German icebreaker Polarstern in the southern autumn of 2022, an unusual species of whale was observed: the Arnoux's beaked whale.

Unique Iron- and Viking-age mortuary houses unearthed in Norway

Recent work published by Dr. Raymond Sauvage and Dr. Richard Macphail in Medieval Archaeology describes the excavation and interpretation of three Iron- and Viking-Age mortuary houses in central Norway, Skeiet, in the village of Vinjeøra.

Using a gamma ray burst to search for violations of Einstein's relativity postulates

Einstein's theory of relativity is based on two assumptions, or postulates. The first is that the laws of physics look the same to everyone traveling in a straight line with no acceleration.

Study finds people are consistently and confidently wrong about those with opposing views

Despite being highly confident that they can understand the minds of people with opposing viewpoints, the assumptions humans make about others are often wrong, according to new research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London, in partnership with the University of Oxford.

New research suggests a way to capture physicists' most wanted particle—gravitons

A team led by Stevens professor Igor Pikovski has just outlined how to detect single gravitons, thought to be the quantum building blocks of gravity—and making that experiment real should be possible with quantum technology, they suggest, in the near future.

Event Horizon Telescope makes highest-resolution black hole detections from Earth

The Event Horizon Telescope (EHT) Collaboration has conducted test observations achieving the highest resolution ever obtained from the surface of the Earth, by detecting light from the centers of distant galaxies at a frequency of around 345 GHz.

Scientists uncover the role of dopamine in mediating short-term and long-term memory dynamics

In a recent study published in Nature, researchers from Stanford University and Yale University have explored the interplay between short-term and long-term memory in animals.

Astronomers spot merging galaxies from 12.8 billion years ago

Astronomers have spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the brightest types of objects in the universe.

Doughnut-shaped region found inside Earth's core deepens understanding of planet's magnetic field

A doughnut-shaped region thousands of kilometers beneath our feet within Earth's liquid core has been discovered by scientists from The Australian National University (ANU), providing new clues about the dynamics of our planet's magnetic field.

Almost half of FDA-approved AI medical devices are not trained on real patient data, research reveals

Artificial intelligence (AI) has practically limitless applications in health care, ranging from auto-drafting patient messages in MyChart to optimizing organ transplantation and improving tumor removal accuracy. Despite their potential benefit to doctors and patients alike, these tools have been met with skepticism because of patient privacy concerns, the possibility of bias, and device accuracy.

Hubble observes an oddly organized satellite galaxy

Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way's closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appears devoid of new star formation and younger stars. In fact, Andromeda III seems to be only about 3 billion years younger than the majority of globular clusters―dense knots of stars thought to have been mostly born at the same time, which contain some of the oldest stars known in the universe.

Astrophysicists use AI to precisely calculate universe's 'settings'

The standard model of the universe relies on just six numbers. Using a new approach powered by artificial intelligence, researchers at the Flatiron Institute and their colleagues extracted information hidden in the distribution of galaxies to estimate the values of five of these so-called cosmological parameters with incredible precision.

Mathematicians debunk GPS assumptions to offer improvements

The summer holidays are ending, which for many concludes with a long drive home and reliance on GPS devices to get safely home. But every now and then, GPS devices can suggest strange directions or get briefly confused about your location. But until now, no one knew for sure when the satellites were in a good enough position for the GPS system to give reliable direction.
