Phys.org / Setting limits on phase transitions in the dark energy era
The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand ...
Phys.org / Bumblebees may self-medicate when exposed to fungal infections
There is an old saying that nature is the best medicine, and it turns out bumblebees might agree. A new study published in the journal Royal Society Open Science suggests that buff-tailed bumblebees (Bombus terrestris) may ...
Phys.org / Diamond clock combines two signals to cut temperature-driven drift
Despite all the advertisements for engagement rings and necklace gifts, natural diamonds are imperfect. Their carbon atoms are arranged in a cubic lattice, but they nonetheless contain several types of crystallographic defects ...
Phys.org / The little red dots of our cosmos might hide something big
Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.
Tech Xplore / A humanoid robot's social expressiveness may backfire when it makes mistakes
For robots to be successfully deployed in real-world environments, humans should trust them enough to cooperate with them. Some roboticists have been trying to determine whether users perceive robots that exhibit socially ...
Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...
Medical Xpress / The anti-aging effects of exercise, without exercise: Self-contracting muscle implants give mice a boost
Exercise does more than keep our minds and bodies healthy. It also protects us against the effects of aging. Scientists have developed self-contracting mini-muscle implants that grow their own blood supply and mimic the biological ...
Phys.org / Scientists capture first molecular-level images of water reorganization during a reaction crucial for life
Some of nature's most important chemical reactions rely on the coupled movement of negatively and positively charged particles. These processes play central roles in photosynthesis, catalysis and biological energy conversion ...
Phys.org / Low temperature graphene growth opens a route to sustainable resource recycling
Graphene is an exceptionally useful material for creating batteries, catalysts and electronic devices. Yet producing graphene typically requires temperatures as high as 900°C (1,652°F), limiting energy efficiency and making ...
Medical Xpress / Nearly one in five Medicaid-eligible adults may miss new 80-hour work rule
A new study found that nearly 20% of eligible adults in Medicaid expansion states are in danger of not meeting the minimum work hours that will be required nationwide beginning Jan. 1. Women, unmarried people, white individuals ...
Tech Xplore / New transistor brings high voltage to microchip scale
Inside every electronic device, the flow of electricity is controlled by a switch called a transistor. For decades, these switches were made from silicon. More recently, engineers have turned to a material called gallium ...
Phys.org / Satellite images show bedrock and glacier collapsed on Nepal-China border, then rivers flooded
As rescue teams searched for missing people following catastrophic flooding along the Nepal-China border, Earth scientists reviewed satellite imagery for clues to the cause and assessed the devastation.
