Phys.org / Much of Earth's 'space dust' may come from unidentified near-Earth asteroids
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
Phys.org / Ancient rocks reveal Earth's past warm periods were cooler than thought
Earth's temperature has been much cooler in the past than previously thought, meaning it could be moving toward the warmest it's ever been.
Science X / Your brain expects each face to move its own way, and notices when a smile breaks that rule
Imagine meeting someone new whose smile feels just a bit wrong. You might think, "this smile is too fast (or slow, or crooked)," even if the movement itself is common. How could your brain sense this subtle "offness" from ...
Tech Xplore / New method improves control over organic semiconductor doping for flexible electronics
Organic semiconductors are paving the way for a new generation of lightweight, flexible electronics, including bendable displays, printable circuits, wearable sensors and devices that harvest energy from their surroundings. ...
Tech Xplore / A soft exoskeleton could restore hand function in people with motor impairments
Recent technological advances have opened valuable possibilities for supporting people with motor impairments or who are recovering from injuries to the brain, spinal cord or nerves. Millions of people worldwide currently ...
Phys.org / The real Moana story: Why the Polynesians suddenly sailed east
Major drought forced people to migrate across the Pacific beyond Samoa and Tonga and toward the Americas, scientists have discovered. With the new live-action "Moana" film hitting cinemas, a team of geographers and climate ...
Phys.org / Programmable light simulates quantum matter across 300 processes without bigger circuits
A team of researchers at the University of Ottawa and its Nexus for Quantum Technologies Institute, in collaboration with researchers from Federico II University in Italy, has developed a programmable quantum simulator that ...
Medical Xpress / Yeast dietary supplement may offer a safe nutritional strategy to boost cancer immunity
Researchers from Trinity College Dublin (TCD) and University College Dublin (UCD) have shown for the first time that a food supplement made from yeast helps the body make stronger immune cells that can fight cancer. The research ...
Medical Xpress / As the US recovers from its latest heat wave, study warns of an increase in hospitalizations for mental health issues
As the U.S. recovers from its July 4 heat wave, a new study in Nature Health warns of an impending uptick in people attending hospitals for mental health and behavioral disorders, according to the first multicountry study ...
Phys.org / Largest viral-protein library gives researchers new way to probe emerging pathogens
To prevent viruses from sickening or killing us—whether it's an individual case of hepatitis B or a COVID pandemic—it's crucial to understand how the proteins they make initiate changes in our bodies that allow them to flourish. ...
Phys.org / Baseline tool could separate alien life signals from geology on ocean worlds
When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because ...
Phys.org / To ancient astronomers, Theta Eridani was brighter for 1,000 years—now we know why
There's a bit of a historical mystery surrounding the star Theta Eridani. Ptolemy in the second century A.D. and al-Sufi in A.D. 964 both recorded Theta Eridani as one of the 13 brightest stars in the sky. Hipparchus may ...
