Researchers use ultrasound holograms to influence brain networks

2025-10-03
The first picture taken of a person nowadays is usually an ultrasound scan in the womb. But the technology is capable of much more than that. Physiotherapists have long used ultrasound to heat bodily tissues, and oncological surgeons use high-intensity ultrasound – and the heat it generates inside the body – to destroy tumours.  Over the last decade, scientists have also been researching how low-intensity ultrasound can be used to influence neural activity in the brain in a targeted manner. Initial clinical trials ...

Unique videos show how trawling restrictions brings back life to the sea

2025-10-03
Trawling restrictions not only benefits fish and shellfish; anemones and corals are also becoming more common, according to a new study from the University of Gothenburg. Twenty-six years of underwater videos from the depths of the Koster Sea also show long-term changes in the ecosystem as the water becomes warmer. The marine wildlife in Kosterhavet National Park has changed rapidly in recent years. The introduction of trawling restrictions in the area for the national park during the last 25 years, brought about a change in the living conditions for the animals that live on the seabed. “Animals ...

Whooping cough can be fatal in young infants, experts warn

2025-10-03
Pertussis, or whooping cough, is on the rise and incidence now exceeds pre-pandemic numbers. While in adults and older children the cough can be bothersome and last for months, pertussis in young infants can be life-threatening. Most children under 2 months of age with pertussis in the United States are hospitalized. In a special article published in Pediatrics, experts strongly encourage vaccination, especially during pregnancy. “Pertussis symptoms are different in infants,” said leading author Caitlin Li, MD, infectious diseases specialist at Ann & Robert H. Lurie Children’s Hospital of Chicago and Assistant Professor of Pediatrics at Northwestern ...

The Lancet: Billions lack access to healthy diets as food systems drive climate and health crises, but sustainable, equitable solutions are within reach, says new EAT-Lancet report

2025-10-02
Building on the landmark 2019 report, the 2025 EAT-Lancet Commission presents the most comprehensive scientific analysis of global food systems to date. It establishes a clear, science-based approach to provide 9.6 billion people with access to healthy diets within planetary boundaries while recognising that healthy and sustainable diets are the foundation of human rights. The report reveals that the global food system contributes to 30% of greenhouse gas emissions and is the largest driver of planetary boundary transgressions through its impacts on climate, biodiversity, freshwater consumption, and land use change.  Although there ...

Countries with highest reported levels of hearing loss have lowest use of hearing aids

2025-10-02
Countries with the highest reported levels of hearing loss also have the lowest reported use of hearing aids, finds international research published in the open access journal BMJ Global Health. And men are generally more likely than women to report difficulties with their hearing, although this gender divide narrows with age, the findings show. An estimated 1.57 billion people—equivalent to 1 in 5 of the world’s population—had hearing loss in 2019. And it’s predicted that it will affect 2.45 billion people by 2050, say the researchers. Hearing loss is associated with an array of problems ...

2025-10-02
Early medical abortion at home up to 12 weeks of pregnancy is safe, effective, and comparable to hospital care, finds a 5 year review of cases in Scotland, where this timeframe is legally permitted, and published online in the journal BMJ Sexual & Reproductive Health. It’s time to extend the current legal limit of 10 weeks to 12 weeks to enable women in the rest of the UK and Europe to choose this option, conclude the researchers. During the COVID-19 pandemic, legislation was introduced throughout Scotland, England, and Wales to allow women to ...

New approach to gravitational wave detection opens the Milli-Hz Frontier

2025-10-02
Scientists have unveiled a new approach to detecting gravitational waves in the milli-Hertz frequency range, providing access to astrophysical and cosmological phenomena that are not detectable with current instruments.   Gravitational waves—ripples in spacetime predicted by Einstein—have been observed at high frequencies by ground-based interferometers such as LIGO and Virgo, and at ultra-low frequencies by pulsar timing arrays. However, the mid-band range has remained a scientific blind spot.   Developed by researchers at the Universities of Birmingham and Sussex, the new detector concept uses cutting-edge optical cavity and atomic clock technologies ...

Exercise lowers disease risk. This researcher wants to understand how

2025-10-02
Don't love the gym? Neither does exercise scientist Ryan Montalvo. But he goes anyway. While any workout can seem daunting, the physical stress of exercise often affords long-term benefits. One advantage is that it triggers a physiological response that allows our cells to adjust to meet future energy demand in what’s known as a hormetic response. With an early career research grant from the American College of Sports Medicine Research Endowment, Montalvo will explore how this response to exercise-induced stress might help overcome noncommunicable diseases. Working ...

Hurricane evacuation patterns differ based on where the storm hits

2025-10-02
A study comparing evacuation patterns in response to two 2024 hurricanes, Milton and Helene, found that people in coastal areas with frequent hurricane exposure were much more likely to travel out of harm’s way compared to people in inland areas who were more likely to stay put. Researchers at Columbia University Mailman School of Public Health led the study. Their findings appear in the journal Environmental Research Letters.   These geographic differences are likely due to a combination of factors, including access to transportation infrastructure, social norms, and risk perception, ...

Strengthening biosecurity screening for genes that encode proteins of concern

2025-10-02
Advances in artificial intelligence-assisted protein engineering are enabling breakthroughs in protein design, but they also introduce biosecurity challenges related to potential production of harmful proteins. Though screening software to detect harmful proteins exists, a new multi-month analysis of such software reports that this software has vulnerabilities; some proteins of concern could evade detection. Critically, the study also offers a way to improve detection rates of proteins of concern going forward. AI-assisted protein design (AIPD) enables powerful advances in medicine and biology, enabling researchers to modify existing proteins or design wholly new ones ...

Global wildfire disasters are growing in frequency and cost

2025-10-02
Wildfire disasters worldwide are growing notably in frequency and cost, according to a new study, with nearly half of the most damaging events over the last 44 years occurring in just the past decade, driven largely by increasingly extreme fire weather in vulnerable, densely populated regions. The findings, informed by an analysis of global reinsurance data and international disaster reports, reveal a concerning trend and highlight the need to adapt for a more fire-prone world. Humans have coexisted with wildfires for millennia, but climate change, land mismanagement, and expansion into flammable landscapes ...

Wildfire management: Reactive response and recovery, or proactive mitigation and prevention

2025-10-02
Catastrophic wildfires – those causing massive damage and soaring suppression costs – are increasing in frequency and intensity worldwide, a trend expected to worsen with climate change. In a Policy Forum, Robert Gray and colleagues use British Columbia (BC), Canada, as a case study of a government at a crossroads: continue reactive spending on suppression and recovery or invest in strategies to reduce future wildfire risk. “Although we focus on BC, this same tough question, along with lessons learned and our main recommendations, apply to regional ...

Phosphine detected in the atmosphere of a low-temperature brown dwarf

2025-10-02
Astronomers using the James Webb Space Telescope have detected the molecule phosphine beyond our Solar System, according to a new study, finding it in the atmosphere of the cold brown dwarf Wolf 1130C. The presence of the phosphorus-containing molecule phosphine (PH3) is well established in the atmospheres of Jupiter and Saturn, as well as in some giant stars. Although models predict that PH3 should be similarly common in gas giant exoplanets and brown dwarfs, searches for the molecule in the atmospheres of those objects have shown it to be in very low abundance, if not totally absent. Using the JWST NIRSpec instrument, Adam Burgasser ...

Scientists develop rapid and scalable platform for in planta directed evolution

2025-10-02
Directed evolution is a laboratory technique that mimics natural selection and allows scientists to evolve genes and the proteins they encode. Traditionally, this technique has been used in microbes, mammalian cells, or in test tubes. Now, researchers led by Prof. GAO Caixia from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences (CAS) and Prof. QIU Jinlong from the Institute of Microbiology of CAS have developed a new system that enables rapid and scalable directed evolution of diverse genes directly ...

New tiny prehistoric fish species unlocks origins of catfish and carp

2025-10-02
The fossil of a tiny fish found in southwestern Alberta provides new insight into the origin and evolution of otophysans, the supergroup of fish that includes catfish, carp and tetras, which today account for two-thirds of all freshwater species. The specimen, studied by researchers at Western University, the Royal Tyrrell Museum of Palaeontology and international collaborators, is a skeleton of a fish about 4 cm long from the Late Cretaceous period (the age of the iconic Tyrannosaurus Rex, about 100.5 million to 66 million years ago.) A new kind of fish entirely, it ...

Plant microbiota: War and peace under the surface

2025-10-02
When we talk about microbiota, we usually think of the one inhabiting our gut. But there is another, less known and equally vital: the plant microbiota. In an article featured on the cover of Science (October 2, 2025), Professor Niko Geldner and his team at the University of Lausanne (Unil) unveil the subtle alliances and rivalries that unfold between bacteria and roots, hidden beneath the soil. Roots and microbes The plant microbiota, or “phytobiome,” brings together communities of bacterial and fungal microorganisms that can be partners, allies—and sometimes enemies. The part most closely associated with roots is called the “rhizospheric” ...

Fossilized ear bones rewrite the history of freshwater fish

2025-10-02
When saltwater fish long ago evolved to live in fresh water, many of them also evolved a more sophisticated hearing system, including middle ear bones similar to those in humans. Two-thirds of all freshwater fish today — including more than 10,000 species, from catfish to popular aquarium fish like tetras and zebrafish — have this middle ear system, called the Weberian apparatus, which allows them to hear sounds at much higher frequencies than most ocean fish can, with a range close to that of humans. University of California, Berkeley paleontologist Juan Liu has now used the structure of this Weberian apparatus in a newly discovered ...

Detection of phosphine in a brown dwarf atmosphere raises more questions

2025-10-02
Phosphorus is one of six key elements necessary for life on Earth. When combined with hydrogen, phosphorus forms the molecule phosphine (PH3), an explosive, highly toxic gas. Found in the atmospheres of the gas giant planets Jupiter and Saturn, phosphine has long been recognized as a possible biosignature for anaerobic life, as there are few natural sources of this gas in the atmospheres of terrestrial planets. On Earth, phosphine is a byproduct of decaying organic swamp matter. Now a team of researchers, led by University of California San Diego Professor of Astronomy and Astrophysics ...
