World’s soft coral diversity retains signature of an ancient, vanished sea

2025-06-24
It is of vital importance to, on occasion, consider how little we know about the spinning rock we all live on. Take coral reefs, for example. Given how much they’ve been studied, you’d think we’ve learned just about everything about them by now. But talk to a marine biologist, and they will quickly disabuse you of this notion. “A majority of the things that are out there on coral reefs are simply unknown to us or haven’t been formally described or named,” said Catherine McFadden, a professor of life sciences at Harvey Mudd College. McFadden is ...

Scientists use gene editing to correct harmful mitochondrial mutations in human cells

2025-06-24
In a step toward treating mitochondrial diseases, researchers in the Netherlands have successfully edited harmful mutations in mitochondrial DNA using a genetic tool known as a base editor. The results, published June 24th in the open-access journal PLOS Biology, offer new hope for people with rare genetic conditions. Mitochondria, often called the powerhouses of the cell, have their own small set of DNA. Mutations in this mitochondrial DNA can lead to a wide range of maternally inherited diseases, cancer, and aging-related conditions. ...

The evolution from reptile-like to upright posture in mammals was highly dynamic and complex

2025-06-24
The transition from sprawling (reptile-like) to more upright (parasagittal) posture and locomotion was a transformative event in mammalian evolution. A study published June 24th in the open-access journal PLOS Biology by Dr. Robert Brocklehurst and Professor Stephanie Pierce at Harvard University, USA and colleagues suggests that parasagittal posture evolved via an indirect, dynamic, and radiating process. Non-mammalian synapsids (tetrapod vertebrates), the ancestors of extant mammals, underwent major musculoskeletal reorganization, including ...

An evolutionary trade-off has limited how fish catch their prey

2025-06-24
A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report June 24th in the open-access journal PLOS Biology. Ray-finned fish are a diverse and widespread group, representing 99% of living fish species. Two key adaptations have helped them thrive: large teeth and extendible jaws. Fish with larger teeth can access a wider range of food sources, while the ability to rapidly extend the upper jaw allows fish to hunt fast-swimming prey by using suction forces to pull them closer. However, these two innovations are rarely found in the same fish species. To find out why, ...

Bats are natural reservoirs for a wide range ...

Head over heels

2025-06-24
For over a century, scientists have puzzled over a fundamental mystery in our evolutionary history: how did mammals go from sprawling like lizards to striding like cats and dogs? This transition—from a sprawled stance (like a lizard) to an upright (parasagittal) posture—marked a pivotal moment in mammal evolution. While the earliest non-mammalian synapsids, the ancestors of living mammals, had a sprawling posture, researchers debated when and how the upright postures of modern mammals evolved. Now, a groundbreaking study in PLOS ...

Some cancer cells just won’t commit: Why that might be good news for neuroblastoma cancer patients

2025-06-24
Neuroblastoma is a cancer that affects the sympathetic nervous system of children. It is unusual among cancers because it shows a range of outcomes: from aggressive, potentially fatal progression to a unique phenomenon where the tumor spontaneously regresses even without treatment. Identifying why some patients regress and others don’t could help thousands of patients. A research group led by Nagoya University believes that the answer may lie in the “uncommitted” state of some neuroblastoma cells. In mice bred to have tumors that were presumed to regress, they discovered a population of “uncommitted" cells that ...

Strategic choices behind accounting standards unveiled in new study

2025-06-24
New study explores why foreign firms listed in the U.S. choose between IFRS and U.S. GAAP. The research finds that firms strategically weigh the flexibility of financial reporting and the costs of compliance, rather than following the common standards in their listing jurisdiction. These insights help explain the real motivations behind financial disclosure decisions and offer guidance for regulators and investors alike. A new study by Dr. Heylel-li Biton of the Hebrew University Business School sheds light on a long-standing question in global finance: Why do foreign firms listed in the United ...

USPSTF recommendation statement on screening for intimate partner violence and caregiver abuse of older or vulnerable adults

2025-06-24
Bottom Line: The U.S. Preventive Services Task Force (USPSTF) recommends that clinicians screen for intimate partner violence in women of reproductive age, including those who are pregnant and postpartum. The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for caregiver abuse and neglect in older or vulnerable adults. Intimate partner violence affects millions of U.S. residents across the lifespan and is often unrecognized. Abuse of older or vulnerable adults by a caregiver or someone else they may trust is common and can result in ...

Charging devices with indoor lighting

2025-06-24
WASHINGTON, June 24, 2025 — When you think of solar panels, you usually picture giant cells mounted to face the sun. But what if “solar” cells could be charged using fluorescent lights? Perovskite solar cells (PeSCs) have emerged as a lower-cost, higher-efficiency alternative to traditional silicon solar cells due to their material structure and physical flexibility. Their large power conversion efficiency rate (PCE), which is the amount of energy created from the amount of energy hitting the cell, makes PeSCs well suited to converting lower light sources into energy. In APL Energy, by AIP Publishing, researchers from National Yang Ming Chiao Tung University in Taiwan ...

Organ-chips may help unlock the mystery of ALS

2025-06-24

In a study published in the peer-reviewed journal Cell Stem Cell, investigators detail how they created “ALS on a chip” and the clues the specialized laboratory chip has already produced about nongenetic causes of the disease, also known as Lou Gehrig’s disease. The work builds ...

E-cigarette and cannabis social media posts pose risks for teens, study finds

2025-06-24
Teens who see social media posts showing cannabis or e-cigarettes, including from friends and influencers, are more likely to later start using those substances or to report using them in the past month, according to surveys done by researchers at the Keck School of Medicine of USC. Viewing such posts was linked to cannabis use, as well as dual use of cannabis and e-cigarettes (vapes). Dual use refers to youth who have used both cannabis and e-cigarettes at some point. The results were just published in JAMA Network Open. The findings come amid a decline in youth e-cigarette use, reported in 2024 by the U.S. Food ...

Brains over bots: why toddlers still beat AI at learning language

2025-06-24
Even the smartest machines can’t match young minds at language learning. Researchers share new findings on how children stay ahead of AI - and why it matters. If a human learned language at the same rate as ChatGPT, it would take them 92,000 years. While machines can crunch massive datasets at lightning speed, when it comes to acquiring natural language, children leave artificial intelligence in the dust. A newly published framework in Trends in Cognitive Sciences by Professor Caroline Rowland of the Max Planck Institute for Psycholinguistics, in collaboration with colleagues at the ESRC LuCiD Centre in the UK, presents a novel framework to explain how children ...
