While the early Mars climate remains an open question, a new study suggests its atmosphere may have been hospitable to life due to volcanic activity which emitted sulfur gases that contributed to a greenhouse warming effect. This finding comes from a study published in Science Advances, led by researchers at The University of Texas at…

In 1951, physicist Julian Schwinger theorized that by applying a uniform electrical field to a vacuum, electron-positron pairs would be spontaneously created out of nothing, through a phenomenon called quantum tunneling. The problem with turning the matter-out-of-nowhere theory into Star Trek replicators or transporters? Enormously high electric fields would be required — far beyond the…

Spintronics, or spin-electronics, is a revolutionary approach to information processing that utilizes the intrinsic angular momentum (spin) of electrons, rather than solely relying on electric charge flow. This technology promises faster, more energy-efficient data storage and logic devices. A central challenge in fully realizing spintronics has been the development of materials that can precisely control…

Nearly 12% of Americans have used GLP-1 drugs for weight loss, including about one-fifth of women aged 50 to 64, according to a new RAND report. Surveying a nationally representative sample of 8,793 Americans, researchers found that 11.8% have used GLP-1 agonists and 14% say they are interested in using the drugs. Meanwhile, 74% say…

The sweetpotato feeds millions worldwide, especially in sub-Saharan Africa, where its natural resilience to climate extremes makes it crucial for food security. But this humble root vegetable has guarded its genetic secrets for decades. Now, scientists have finally decoded its complex genome, revealing an intricate origin story and providing powerful tools to help improve this…

You are what you eat, it turns out — even if your last meal was 150 million years ago. While the grub itself may be long gone, a record of dinosaurs’ favorite foods has been stowed away in their ancient tooth enamel over the last eon. When researchers at The University of Texas at Austin…

Researchers including those at the University of Tokyo have made a surprising discovery hiding in people’s mouths: Inocles, giant DNA elements that had previously escaped detection. These appear to play a central role in helping bacteria adapt to the constantly changing environment of the mouth. The findings provide fresh insight into how oral bacteria colonize…

Octopuses are among the most neurologically complex invertebrates, famed for their extraordinary dexterity. Their eight arms allow them to capture hidden prey, communicate, explore, and even mate across varied habitats. Although octopus arms rank among some of the most flexible structures in nature, their full range of movement has rarely been studied in the wild…
