Extinction Risks Remain High for Wild Pandas

Populations of giant pandas in the wild are more fragmented and isolated than they were 30 years ago and many continue to face a high risk of extinction despite recent gains in the species’ overall numbers, a new study by Chinese and American scientists finds. Climate change, habitat loss and reduced breeding viability — an […]

Tool Predicts Sudden Death in Inflammatory Heart Disease

Johns Hopkins University scientists have developed a new tool for predicting which patients suffering from a complex inflammatory heart disease are at risk of sudden cardiac arrest. Published in Science Advances, their method is the first to combine models of patients’ hearts built from multiple images with the power of machine learning. “This robust new personalized […]

First detection of light from behind a black hole

Watching X-rays flung out into the universe by the supermassive black hole at the center of a galaxy 800 million light-years away, Stanford University astrophysicist Dan Wilkins noticed an intriguing pattern. He observed a series of bright flares of X-rays – exciting, but not unprecedented – and then, the telescopes recorded something unexpected: additional flashes of X-rays […]

A sleep study’s eye-opening findings

Subjectively, getting more sleep seems to provide big benefits: Many people find it gives them increased energy, emotional control, and an improved sense of well-being. But a new study co-authored by MIT economists complicates this picture, suggesting that more sleep, by itself, isn’t necessarily sufficient to bring about those kinds of appealing improvements. The study […]

Earthly rocks point way to water hidden on Mars

[embedded content] A combination of a once-debunked 19th-century identification of a water-carrying iron mineral and the fact that these rocks are extremely common on Earth, suggests the existence of a substantial water reservoir on Mars, according to a team of geoscientists. “One of my student’s experiments was to crystalize hematite,” said Peter J. Heaney, professor […]

Astronomers discover how to feed a black hole

A study led by the researcher Almudena Prieto, of the Instituto de Astrofísica de Canarias (IAC), has discovered long narrow dust filaments which surround and feed black holes in the centres of galaxies, and which could be the natural cause of the darkening of the centres of many galaxies when their nuclear black holes are […]

City-living bees benefit most from specific types of urban ‘greening’

Converting vacant urban lots into greenspaces can reduce blight and improve neighborhoods, and new research shows that certain types of such post-industrial reclamation efforts offer the added bonus of benefiting bees. Ohio State University researchers studying ways to encourage biodiversity in vacant urban lots found that experimental plots surrounded by 15 or more connected acres […]

Understanding past climate change ‘tipping points’ can help us prepare for the future

Of all the creatures on Earth, humans manipulate their environments the most. But, how far can we push it before something drastic happens? Scientists are calling for a better understanding of past extreme climate change events in an attempt to anticipate future changes. Enter geoarchaeologist and anthropologist C. Michael Barton at Arizona State University. The School of Human Evolution […]
