A team of scientists led by the University of Colorado Boulder has identified 30 new areas critical for conserving biodiversity in the Southern Ocean surrounding Antarctica. In a study published Aug. 15 in the journal Conservation Biology, the researchers warn that without greater protection to limit human activities in these areas, native wildlife could face…

A team of researchers has made strides in understanding the formation of massif-type anorthosites, enigmatic rocks that only formed during the middle part of Earth’s history. These plagioclase-rich igneous rock formations, which can cover areas as large as 42,000 square kilometers and host titanium ore deposits, have puzzled scientists for decades due to conflicting theories…

A major international study has explained how bread wheat helped to transform the ancient world on its path to becoming the iconic crop that today helps sustain a global population of eight billion. “Our findings shed new light on an iconic event in our civilisation that created a new kind of agriculture and allowed humans…

In a new study, researchers synthesised data from 206,873 people across 47 studies, finding that digital health tools — like mobile apps, websites, and text messages — can significantly improve health and wellbeing by keeping you active, boosting steps, and improving your diet and sleep. Specifically, electronic and mobile health interventions can help people achieve:…

Using data from NASA’s James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex history for Psyche, important context for the NASA spacecraft en route to this interesting asteroid orbiting the Sun between Mars and Jupiter….

Cell-cell adhesion-induced patterning in keratinocytes can be explained by just starvation and strong adhesion, Hokkaido University researchers find. Fingerprints are one of the best-recognised examples of pattern formation by epithelial cells. The primary cells in the epithelium are the keratinocytes, and they are known to form patterns at the microscopic and macroscopic levels. While factors…

In work conducted both at UC Santa Barbara and the Physics of Life Excellence Cluster of TU Dresden, biophysicist Otger Campàs and his research group have found that cell nuclei control the architecture and mechanics of eye and brain tissues during embryonic development. These results add a new role for the cell’s nucleus in tissue…

A new UC Riverside study demonstrates that calorie restriction doesn’t deter mice from exercising, challenging the belief that dieting drains workout energy. The study, published in the journal Physiology & Behavior, shows that cutting calories by 20% did not significantly reduce the distance that mice voluntarily chose to run each day. The researchers set out…

When Katey Walter Anthony heard rumors of methane, a potent greenhouse gas, ballooning under the lawns of fellow Fairbanks residents, she nearly didn’t believe it. “I ignored it for years because I thought ‘I am a limnologist, methane is in lakes,’” she said. But when a local reporter contacted Walter Anthony, who is a research…

While seeking to unravel how marine algae create their chemically complex toxins, scientists at UC San Diego’s Scripps Institution of Oceanography have discovered the largest protein yet identified in biology. Uncovering the biological machinery the algae evolved to make its intricate toxin also revealed previously unknown strategies for assembling chemicals, which could unlock the development…

Scientists often seek answers to humanity’s most pressing challenges in nature. When it comes to global warming, geological history offers a unique, long-term perspective. Earth’s geological history is spiked by periods of catastrophic volcanic eruptions that released vast amounts of carbon into the atmosphere and oceans. The increased carbon triggered rapid climate warming that resulted…

A discovery by a three-member Albert Einstein College of Medicine research team may boost the effectiveness of stem-cell transplants, commonly used for patients with cancer, blood disorders, or autoimmune diseases caused by defective stem cells, which produce all the body’s different blood cells. The findings, made in mice, were published today in the journal Science….

Early-stage trials in Alzheimer’s disease patients and studies in mouse models of the disease have suggested positive impacts on pathology and symptoms from exposure to light and sound presented at the “gamma” band frequency of 40 Hz. A new study zeroes in on how 40Hz sensory stimulation helps to sustain an essential process in which…

Growing functional human organs outside the body is a long-sought “holy grail” of organ transplantation medicine that remains elusive. New research from Harvard’s Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engineering and Applied Science (SEAS) brings that quest one big step closer to completion. A team of scientists created a…

Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth…

Everyone gets sleepy at work from time to time, especially after a big lunch. But for people whose jobs involve driving or working with heavy machinery, drowsiness can be extremely dangerous — if not outright deadly. Drowsy driving contributes to hundreds of fatal vehicle accidents in the U.S. each year, and the National Safety Council…

By recruiting the immune system to combat tumor cells, immunotherapy has improved survival rates, offering hope to millions of cancer patients. However, only about one in five people responds favorably to these treatments. With a goal of understanding and addressing immunotherapy’s limitations, researchers at Washington University School of Medicine in St Louis have found that…
