Phys.org / Frequent flares from TRAPPIST-1 could impact habitability of nearby planets
Like a toddler right before naptime, TRAPPIST-1 is a small yet moody star. This little star, which sits in the constellation Aquarius about 40 light-years from Earth, spits out bursts of energy known as "flares" about six ...
Phys.org / KIC 5623923 is a faint eclipsing binary exhibiting Delta Scuti-type pulsations, observations find
Using NASA's Kepler space telescope, Chinese astronomers have observed a binary star system known as KIC 5623923. As a result, they found that the investigated system is a faint eclipsing binary experiencing Delta Scuti-type ...
Phys.org / Spain not ruling out lab leak as cause of swine fever outbreak
Spain's government said Friday it had not ruled out an accidental laboratory leak as the cause of an outbreak of African swine fever that has rocked the country's lucrative pork industry.
Medical Xpress / Exercise slows tumor growth in mice by shifting glucose uptake to muscles
It's well known that exercise is good for health and helps to prevent serious diseases, like cancer and heart disease, along with simply making people feel better overall. However, the molecular mechanisms responsible for ...
Medical Xpress / Brain enzyme that drives nicotine addiction and smoking dependence identified
Nicotine addiction remains one of the most persistent public health challenges worldwide, driven by changes in the brain that reinforce repeated use and make quitting extremely difficult. For decades, scientists have focused ...
Phys.org / High-energy-density barocaloric material could enable smaller, lighter solid-state cooling devices
A collaborative research team from the Institute of Solid State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has discovered a high-energy-density barocaloric effect in the plastic ...
Phys.org / Birds shift to higher mountain elevations in Europe as climate warms
Many bird species have moved toward colder areas in the mountains of Europe as the climate has warmed over the past two decades. Sunny southern slopes attract birds to live at higher elevations than do shadier northern slopes.
Tech Xplore / Overparameterized neural networks: Feature learning precedes overfitting, research finds
Modern neural networks, with billions of parameters, are so overparameterized that they can "overfit" even random, structureless data. Yet when trained on datasets with structure, they learn the underlying features.
Phys.org / How volcanic eruptions set off a chain of events that brought the Black Death to Europe
Clues contained in tree rings have identified mid-14th-century volcanic activity as the first domino to fall in a sequence that led to the devastation of the Black Death in Europe.
Phys.org / 'Free-range' dinosaur parenting may have created surprisingly diverse ancient ecosystems
Picture a baby Brachiosaurus the size of a golden retriever, hunting for food with its siblings while dodging predators that would happily eat it. Meanwhile, its parents—towering over 40 feet tall—are dozens of miles ...
Medical Xpress / CDC panel votes to no longer recommend hepatitis B shot for newborns
A federal vaccine advisory committee has voted to change a long-standing recommendation that all newborns in the United States receive the hepatitis B vaccine on the day they are born.
Phys.org / An adolescent growth spurt in young stars helps giant planets form
Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star called a protoplanetary disk. ...
