Phys.org / An ultramassive white dwarf half Earth's size may hold a rare oxygen-neon core
Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The finding is important because the composition of a white dwarf's core ...
Medical Xpress / Study reveals prefrontal cortex can hinder learning more efficient behaviors
The prefrontal cortex, a brain region long associated with learning more flexible behaviors, can sometimes block the ability to think outside the box, a new study in mice shows. The finding by biologists at Emory University ...
Medical Xpress / Omega-3 plus low-dose aspirin produces antibiotic-like results against severe periodontitis
A combination of omega-3 and low-dose acetylsalicylic acid (ASA) produced results comparable to antibiotics in treating severe periodontitis. This conclusion is based on a study conducted by researchers affiliated with Albert ...
Phys.org / Neanderthal growth hormone receptor increases muscle mass in people today, study shows
Neanderthals were generally more strongly built than most people living today. Their bones show signs of large muscles, and they had characteristic features such as prominent brow ridges and relatively short tooth roots.
Phys.org / Reduced gravity pushes people toward simpler movement patterns, experiments suggest
From reaching for a cup of coffee to tying your shoelaces, gravity shapes nearly all human movement. So how do our bodies react when that familiar force begins to change? Texas A&M University researchers are exploring the ...
Phys.org / Why some people are mosquito magnets while others get away unbitten
Some mosquitoes really are picky eaters. They will not just stick their proboscis into any old human. We know this anecdotally, with some people claiming they are always bitten while others are completely ignored, though ...
Phys.org / Hong Kong weather observatory posts record high temperature
Hong Kong's weather observatory posted a record high temperature of 36.9°C (98°F) on Sunday as Typhoon Dolphin swept warm air over the city, the meteorological service said.
Phys.org / Over half of people are unaware of the environmental effects of sunscreen
This summer, millions of people across the country have been digging out sunscreen to protect themselves from a record-breaking series of heat waves.
Phys.org / First measurement of antineutrinos from spent nuclear fuel confirms emissions persist after reactor shutdown
Even when the lights go out and nuclear reactors are turned off, the story inside the reactor core still has a great deal to tell. Radioactive, long-lived fission products continue to decay for months or even years, producing ...
Medical Xpress / A precise neuronal mechanism allows the brain to plan future routes to remembered goals
When humans and other animals move through familiar or unfamiliar environments, their brains rely on numerous intricate neural processes to decide which path to take next. Past studies have identified a specific population ...
Medical Xpress / Rising temperatures linked to higher risk of homicide and suicide in Mexico and Brazil
As temperatures on Earth continue to rise, some researchers have been trying to understand how climate change influences people's physical and mental health. Some past studies have found an association between warmer weather ...
Phys.org / JWST study suggests a handful of 'leaky' galaxies reionized the early universe
A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of "leaky" galaxies was responsible for cosmic reionization. The paper outlining this work ...
