Researchers propose an unconventional way to generate light made from entangled photons. In the graphic above, photons meet the electrons of a helium atom, which then emits two entangled photons.

Researchers have run through near-perfect fossils of the world’s first gliding reptile with a fine-toothed comb and untangled hitherto unknown facets to discover it was a change in tree canopy which likely facilitated such flight in these creatures.

Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and ‘antimatter’ — particles that are matter counterparts but with opposite charge. But then, as space expanded, the universe cooled. Today’s univer…

Researchers developed a system that streamlines the process of federated learning, a technique where users collaborate to train a machine-learning model in a way that safeguards each user’s data. The system reduces communication costs of federated lear…

While on missions without access to clean water, U. S. Marines face the challenge of procuring and storing enough drinking water to sustain them. Chemical engineers are working toward a realistic purification option that is portable, lightweight and ea…

Stars are the machines that sculpt the universe, yet scientists don’t fully know how they form. To understand the frenzied ‘baby boom’ of star birth that occurred early in the universe’s history, researchers turned to the Small Magellanic Cloud, a sate…

One of the most upsetting aspects of age-related memory decline is not being able to remember the face that accompanies the name of a person you just talked with hours earlier. While researchers don’t understand why this dysfunction occurs, a new study…

Weedy rice is a closely related cousin of crop rice. It aggressively competes with cultivated rice in the field, leading to loss of yield and reductions in harvest quality that compromise market value. Biologists used whole-genome sequences of 48 conte…

Agriculture drives more than 90 percent of tropical deforestation. Halting deforestation will require a step-change in approach and to be effective measures must address underlying and indirect roles of agriculture, says a new study.

Multiple climate tipping points could be triggered if global temperature rises beyond 1.5°C above pre-industrial levels, according to a major new analysis. Even at current levels of global heating the world is already at risk of passing five dangerous …

A household microwave oven modified by an engineering professor is helping to cook up the next generation of cellphones, computers and other electronics after the invention was shown to overcome a major challenge faced by the semiconductor industry.

The question of what makes modern humans unique has long been a driving force for researchers. Comparisons with our closest relatives, the Neanderthals, therefore provide fascinating insights. The increase in brain size, and in neuron production during…

A new study suggests that many more planets may have large amounts of water than previously thought–as much as half water and half rock. The catch? All that water is probably embedded in the rock, rather than flowing as oceans or rivers on the surface.

Many models predict that climate change will fuel stronger and more frequent El Niño events. However, our knowledge of ENSO and its influence on ecosystems only extends back about 200 years, making it difficult to understand what the long-term future w…
