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 / 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 / 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 ...
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 / 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 / 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.
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, ...
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 ...
Phys.org / Moon base missions face an unseen threat, and these simulations show where it could strike first
Researchers have developed a novel virtual model for simulating how astronauts in future moon base operations might interact with each other and with their environment, with preliminary simulations revealing potential opportunities ...
Phys.org / 'Feathered dragon' has some of the longest tail feathers ever found on a fossil bird
Birds have all kinds of fancy decorations for attracting mates—male peacocks have a fan of feathers accented with shimmering blue eye-spots, birds of paradise do courtship dances that highlight their fluffy plumes, and female ...
Tech Xplore / Breaking the optical barrier: Terahertz tech could help enable quantum internet security
A new method to distribute cryptographic keys using terahertz waves could help enable secure communication in the quantum-powered internet of the future, researchers say. Engineers from the University of Glasgow are pioneering ...
