Phys.org / Perfect randomness realized for the first time
Creating perfect randomness is surprisingly difficult. Even modern random number generators never generate completely ideal random numbers: small systematic errors can result in some numbers appearing slightly more frequently ...
Phys.org / Fake predator eyes scare off seabirds until they learn they're not real
In Danish fisheries, fish-eating seabirds are a menace. They often swoop down and feed on fish trapped in nets, which can hit profits and also sometimes lead to the accidental death of the birds. So scientists deployed an ...
Phys.org / The Southwest's drought is shrinking wildlife's suitable habitat, with predators hit hardest
As people in the United States are coping with historic drought conditions, the country's wildlife is also facing problems because of the extreme aridity. Herbivores, omnivores, and carnivores in the southwestern U.S. have ...
Medical Xpress / How gut microbes help shape how many calories you absorb from food
Food labels make calories seem simple. They show the number of calories per serving, which is calculated based on how much fat, carbohydrates and protein the food contains. But inside the body, digestion is far more complicated. ...
Phys.org / New 'AI scientists' are improving—but reveal their fundamental limits
Many of the most exciting discoveries in science involve highly specialized knowledge and making connections between far-flung facts. Scientists must combine deep analysis with broad reasoning strategies.
Phys.org / Reading brachycephalic dogs' facial expressions requires extra cognitive processing by humans
People often look to dogs' behavior, especially their facial expressions, for indications of their states of mind. Numerous studies show that this is a popular interpretation strategy. However, modern dog breeds vary greatly ...
Phys.org / Indonesia says its giant sea wall will stop flooding. Is this climate adaptation or a costly folly?
Indonesia plans to build a "giant sea wall," more than 500 kilometers long, to defend Java's north coast from rising sea levels.
Science X / Male cockatoos' 'bro-code' means winter buddies become spring nesting neighbors
Ever thought bird friendships mattered for real estate? For male cockatoos, winter social circles surprisingly dictate where they build their spring nests, proving that even in the wild, your buddies can be your best neighbors.
Phys.org / Researchers push back fundamental limit on energy transfer between particles without 'spilling' radiation
Researchers at TU/e have demonstrated that energy transfer without loss via light or heat can occur over much greater distances than previously thought possible thanks to vibrations in microscopic gold rods. They succeeded ...
Medical Xpress / Why caffeine can sabotage deep sleep even when you still get eight hours
Evening coffee has sparked controversy for years. Some people fall asleep without difficulty, while others toss and turn for half the night. However, a growing body of research suggests the question of whether coffee makes ...
Tech Xplore / It looks like a sea urchin, but this strange 20-legged machine is rewriting what robots can do
Symmetry is everywhere in nature, from the bilateral form of vertebrates to the radial geometry of starfish. For decades, roboticists have tried to copy these shapes and their abilities with bodies that look like humans, ...
Phys.org / Metamaterials enable control of heat transfer at nanoscale, potentially transforming energy and electronics
Heat behaves in predictable ways: a hot cup of coffee cools, a laptop warms your hands, the sun heats Earth. But at scales thousands of times smaller than a human hair, those rules begin to break down, and scientists are ...
