An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum o...
Animal-bone records reveal how cattle and sheep fueled medieval England's changing economy
As populations expanded in medieval England, key changes occurred in the uses of cattle and sheep to produce food and materials, according to a study published...
New nanostructure makes non-linear light conversion 72,000 times more efficient

Sorry, this neutrino laser won't work, physicists say
Neutrinos are pervasive yet intangible particles that permeate the universe, streaming through whole planets, stars and our bodies by the trillions each second....
Weak sea-surface temperature gradients may fuel stronger tropical cyclones
The fact that the ocean gets colder as you go deeper is fairly intuitive, but a similar gradient exists along the surface of the ocean, even at scales of 1 kilo...
Dolphin-feeding tourism contributes to predicted dolphin decline
A study published in the journal Oikos, titled "Forecasting the impact of food-provisioning and other stressors on a marine top-predator population," found that...
When biology inspires mathematics: Hidden symmetries explain why widely used evolutionary methods can give false answers
Why do some groups of organisms contain thousands of species while others have only a handful? Evolutionary biologists have spent decades trying to answer this...
Iguanodon shinbone growth may be first evidence of an infected skin ulcer in a dinosaur
Fossilized bones can reveal a wealth of details about animals, including their size, appearance, what they ate and any injuries they may have suffered. In a pap...
How can we improve school attendance?
Poor school attendance can negatively affect young people's behavior and future health. It is a growing public health concern because rates of persistent school...
Young sunlike system reveals comets may carry water toward forming planets
Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star similar to our sun. The observatio...
How cells teach themselves to move together
Scientists have long wondered how cells organized into sheets begin to move together to form organs, especially when the sheets form closed, sphere-like surface...
Health record analysis of one million cattle identifies early prevention as key to reducing feedlot respiratory deaths
New research involving more than 1 million Australian feedlot cattle has found that the strongest predictors of death from bovine respiratory disease (BRD) are...
