Answers to existence of alien life might be found in Earth’s deep-sea volcanoes

2025-07-14
AMHERST, Mass. — While popular culture commonly depicts extraterrestrial life as little green men with large, oval-shaped heads, it’s most likely that if there is life beyond our planet and within our solar system, it is microbial. Recently, NASA awarded University of Massachusetts Amherst microbiologist James Holden $621,000 to spend the next three years using his expertise to help predict what life on Jupiter’s moon Europa might look like. For that, Holden turned to an unexpected place: the volcanoes a mile beneath our own oceans. Jupiter’s moon, Europa, has a frozen surface, but astronomers believe that beneath all that ice lies a salty, liquid ocean ...

New study reveals widespread and overlooked flooding across NC

2025-07-14
A new study from UNC-Chapel Hill reveals that repetitive flooding in North Carolina is far more common and more widespread than previously recognized, with over 20,000 buildings flooding multiple times between 1996 and 2020. The study, which mapped 78 flood events across roughly three-quarters of the state, fills a major gap in understanding the full impacts of flooding on communities well beyond the state’s coastal floodplains.  Until now, detailed flood maps have existed for only a handful of past events. The research team created high-resolution maps for more than 70 previously unmapped floods, linking them to the exact locations ...

In a competitive world, mean leaders look smart

2025-07-14
People who view the world as a savage social jungle are more likely to admire antagonistic leaders, praising their competence, while those who see the social world as cooperative and benign might just call those leaders clueless, according to research published by the American Psychological Association. “Why do some people see antagonistic behavior in leaders – especially when it’s particularly mean or forceful or disagreeable – as a sign of incompetence, while others view it as a mark of savvy leadership?” said Christine Nguyen, a doctoral student at Columbia ...

With intensifying global warming and climate change, drought has become a major threat to global agriculture, impacting crop yields and food security. To survive such adverse events, plants have evolved several strategies. One such strategy to counteract water scarcity is ‘stomatal closure,’ where stomata—the tiny pores on leaf surfaces responsible for gaseous exchange—close to limit water loss. This process is regulated by the plant hormone abscisic acid (ABA), which plays a crucial ...

Pusan National University researchers unveil game-changing UV-fueled shape-shifting and shape-fixing smart materials

2025-07-14
Magnetic micropillar arrays consist of tiny, vertical pin-shaped structures, arranged in a grid-like pattern. These micropillars can change their shape to a pre-programmed geometry when exposed to a magnetic field. They are made from magnetically responsive composites, comprising rubbery polymers like polydimethylsiloxane (PDMS) embedded with magnetic particles. These composites can change their shape and recover repeatedly without any deterioration. Unfortunately, conventional magnetic micropillar arrays can only hold their changed shape temporarily while the magnetic field is being applied. Previous studies have explored various approaches to address this issue, including water-soluble ...

How new genes get switched on

2025-07-14
Most genes are ancient and shared across species. But a small subset of genes are relative newcomers, spontaneously emerging from stretches of DNA that once encoded nothing at all. Now, after nearly a decade of charting these genes in fruit flies, researchers have discovered how these de novo genes are regulated. In complementary studies, in Nature Ecology & Evolution and PNAS, the team showed how transcription factors and genomic neighbors switch these genes on and integrate them into cellular networks—the first studies to identify these master regulators. Together, the findings shed light on how new genes become ...

Regrowing hearing cells: New gene functions discovered in zebrafish offer clues for future hearing loss treatments

2025-07-14
KANSAS CITY, MO — July 14, 2025 — While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ears are damaged, the result is often permanent hearing loss, deafness, or balance problems. In contrast, animals like fish, frogs, and chicks regenerate sensory hair cells effortlessly. Now, scientists at the Stowers Institute for Medical Research have identified how two distinct genes guide the regeneration of sensory cells in zebrafish. The discovery improves our understanding of how regeneration works in zebrafish and may guide future studies ...

Astronomers find a giant hiding in the ‘fog’ around a young star

2025-07-14
Astronomers have detected a giant exoplanet – between three and ten times the size of Jupiter – hiding in the swirling disc of gas and dust surrounding a young star. Earlier observations of this star, called MP Mus, suggested that it was all alone without any planets in orbit around it, surrounded by a featureless cloud of gas and dust. However, a second look at MP Mus, using a combination of results from the Atacama Large Millimeter/submillimeter Array (ALMA) and the European Space Agency’s Gaia mission, suggest that the star is not alone after all. The international team of astronomers, led by the University of Cambridge, detected a large gas giant in the star’s ...

New label-free imaging tracks cancer treatment in single cells

2025-07-14
Spotting the Missteps: How MiROM Detects Protein Misfolding in Cancer Cells MiROM identifies proteins by using mid-infrared light to detect molecular vibrations – essentially the natural “dance” of molecules within protein structures. Unlike optical spectroscopy, which measures light attenuation, optoacoustics capture ultrasound waves generated when proteins absorb infrared light. This absorption causes a tiny, localized temperature increase, leading to transient expansion of medium surrounding the protein and the emission of ultrasound waves. By analyzing these signals in real time, MiROM can detect structural changes ...
