Phys.org / Controlled cracking technique prints quantum dots into tiny pixels for sharper displays
Recent technological advances have enabled the development of increasingly sophisticated, sharper displays for electronic devices. Many modern displays use light-emitting diodes, or LEDs, tiny semiconductor-based components ...
Phys.org / How to spot the Perseid meteor shower, a summer light show that promises to dazzle
The Perseid summer light show is back—and viewing conditions are especially promising for the Northern Hemisphere.
Phys.org / Early snakes explored life underground, on land and at sea
Snakes are highly modified lizards, with more than 4,000 living species today. The origin of snakes has long been one of evolutionary biology's most debated questions. Their sparse fossil record has made it hard to pin down ...
Phys.org / Oldest known giant rock scallop bead suggests California coastal trade began millennia earlier
Archaeologists have discovered two giant rock scallop beads that push back the clock on the first appearance of these high-status ornaments. The discovery shows that these prized marine beads were traded hundreds of miles ...
Phys.org / Cosmic filaments help set first limits on dark matter's decay into gravitons
Composing some 85% of the universe's total mass, dark matter betrays its presence only through gravity, unlike ordinary matter. Yet through new research published in Physical Review D, a team led by David Dunsky of New York ...
Phys.org / New catalyst with 75% less platinum promises to reduce the cost of hydrogen fuel cells
The high cost of platinum is one of the main barriers to the wider adoption of hydrogen fuel cells. Now, researchers at IMDEA Materials Institute have developed a catalyst that delivers the same performance while using 75% ...
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 / Charge-based strategy improves controlled delivery of therapeutic peptides from gelatin-based materials
Rice University engineers have developed a new strategy for controlling how therapeutic peptides are released from gelatin-based materials, a step that could make the small but powerful molecules more useful in tissue engineering ...
Phys.org / Tiny particles defy action-reaction symmetry to stay in motion
From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active ...
Medical Xpress / Protein 'switch' determines whether liposarcoma cells will become aggressive
New research from an expert in cancer biology explains what triggers liposarcoma cells to become more or less aggressive and identifies potential targets that could keep aggressive tumors in check. A study led by Blake Wilde, ...
Medical Xpress / Low-fat vegan diet cuts dietary energy density by nearly a third, helping explain weight loss
A low-fat vegan diet lowers the energy density of the foods people eat by roughly 30%, allowing them to eat satisfying amounts of food while taking in fewer calories and losing weight—without deliberately restricting calories—according ...
Phys.org / Australia has pledged to restore nature. But could we ever bring back lost ecosystems?
Nature is not doing well in Australia. Many unique mammals, birds and insects are struggling. Entire ecosystems are collapsing.
