Phys.org / Six unusual structures identified at Earth's core-mantle boundary with the help of deep learning
Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study ...
Medical Xpress / Self-control matures later than working memory in adolescence, large analysis finds
Adolescence, the developmental phase between childhood and adulthood, is marked by substantial mental, emotional and social changes. Past psychological studies suggest that during this stage, humans gradually acquire greater ...
Medical Xpress / Disabling a gene brake in pancreatic cells unlocks insulin-producing potential
Type 1 and 2 diabetes are ultimately caused by a shortage of beta (β) cells, which are present in the pancreas and produce insulin to control blood sugar. Researchers from Harvard Medical School found that they can tweak ...
Phys.org / Extreme pressure turns blue pigment into record-long single-atom copper chains
As the electronics in our technology keep shrinking, traditional silicon-based chips are approaching their fundamental physical limits. Yet the wires connecting them might be able to shrink beyond conventional dimensions, ...
Phys.org / 'Quiet' pulsar suddenly reveals three glitches in 15 years of observations
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery. ...
Phys.org / How bird movements are helping researchers track a global virus
While the highly virulent avian influenza strain has only recently been discovered on Australian shores, researchers at Deakin University have been working behind the scenes for years, anticipating what an outbreak might ...
Phys.org / The extinct American 'cheetah' was not a cheetah after all
With their slender bodies and long front legs, Miracinonyx trumani—often nicknamed the "American cheetah"—was long thought to be a North American analog of the African big cat. But in a new study published in the journal ...
Phys.org / Growing up socially isolated linked to young people becoming NEET
About 1 million young people in the UK are not in education, employment or training (NEET). The consequences for their health and income can be significant and long-lasting, with costs to the economy as well.
Medical Xpress / EVAOLD trial provides guidance on treating older patients after a heart attack
A routine invasive approach should not be replaced with a more selective approach in older patients with the most common type of heart attack. This was the main finding of the EVAOLD trial presented in a Hot Line session ...
Medical Xpress / New data presented on the use of coronary artery calcium for cardiovascular risk assessment
There was no difference in major cardiovascular events when statin initiation was based on coronary artery calcium compared with traditional risk factor assessment, according to results presented in a Hot Line session today ...
Medical Xpress / End of free school meal program led to increased stress and hunger, poorer diets and reduced focus, say teachers
How did students' diets and behavior change after the expiration of a pandemic-era universal free school meal program in 2022? Researchers asked teachers for their observations of the impact on students and found that teachers ...
Phys.org / Small molecular substitutions reshape energy pathways behind aggregation-induced emission
Certain chemical substances, broadly called luminogens, have an inherent ability to emit light. Most fluorescent molecules emit light in solution but lose their emission in the solid state, where the molecules aggregate.
