Image: Hubble observes jellyfish galaxy JO206

The jellyfish galaxy JO206 trails across this image from the NASA/ESA Hubble Space Telescope, showcasing a colorful star-forming disk surrounded by a pale, luminous cloud of dust. A handful of foreground bright stars with crisscross diffraction spikes stands out against an inky black backdrop at the bottom of the image. JO206 lies over 700 million light-years from Earth in the constellation...

New study takes a high-level look at Nazca boobies' breeding

Nazca boobies can live to 28 years of age, but in their late teens, their ability to raise chicks declines substantially. Why their breeding drops in old age has plagued Wake Forest University Professor of Biology David Anderson for years. But a new study, published in Ecology and Evolution, may help answer the question, by looking at their ability to forage, or search for and capture food.

Wireless sensor enables real-time spoilage alerts on food

Food waste and food-borne diseases are among the most critical problems urban populations face today. They contribute to greenhouse emissions tremendously and amplify economic and environmental costs. Since food spoilage remains the main reason for this waste, the circumstances of processing, transporting, and preserving food still need to be improved in line with current technological...

Eddies: Circular currents and their influence on the world's hottest ocean

Water from the Pacific Ocean flows into the Indian Ocean via the Indonesia Archipelago thanks to a vast network of currents that act as a conveyor belt, transporting warmth and nutrients. Currents can sometimes form circular motions and these are known as eddies. An international group of researchers has modeled the impacts of eddies on the currents that carry water from the Pacific Ocean to the...

The first prehistoric wind instruments discovered in the Levant

Although the prehistoric site of Eynan-Mallaha in northern Israel has been thoroughly examined since 1955, it still holds some surprises for scientists. Seven prehistoric wind instruments known as flutes were recently identified. The discovery of these 12,000 -year-old aerophones is extremely rare -- in fact, they are thought to be the first to be discovered in the Near East.

Scientists demonstrate 3D 'bio-printing' inside organoids growing in hydrogels

Scientists from the NIHR Great Ormond Street Hospital Biomedical Research Centre (a collaboration between GOSH and UCL), London, and University of Padova, Italy, have shown for the first time how 3D printing can be achieved inside "mini-organs" growing in hydrogels—controlling their shape, activity, and even forcing tissue to grow into "molds."
