How plants rot: New method decodes hidden decomposers of wood and leaves
2025-08-28
FRANKFURT. When a tree dies, it forms the foundation for new life: In a slow, invisible process, leaves, wood and roots are gradually decomposed – not by wind or weather but by millions and millions of tiny organisms. Fungi thread their way through the dead wood and degrade cell walls. Tiny animals such as insect larvae and mites gnaw through the tissue. And something very important happens in the process: The carbon stored in the plant is released, ultimately placing it at the disposal of plants again for the purpose of photosynthesis. But what exactly is responsible for performing this task in the global ...

COPD is an inflammatory lung disease, comprising several conditions, including chronic ...
First global guidelines for pregnancy and inflammatory bowel disease developed
2025-08-28
For women with inflammatory bowel disease (IBD), pregnancy can be an uncertain time due to limited clinical data about how IBD medications impact pregnancy outcomes and infants who have been exposed to IBD medications in utero.
As a matter of policy, pregnant women are excluded from clinical trials of experimental therapies for IBD and when a new therapy achieves regulatory approval, there is only animal safety data, but no human pregnancy safety data.
For patients with IBD, stopping medication ...

Bio-inspired, self-cleaning sweat sensors for comfortable wearable health monitoring
2025-08-28
Wearable sensors can help prevent critical health issues by continuously monitoring physiological factors in real time. Specifically, sweat monitoring can provide valuable insights into electrolyte balance and overall health. Sodium concentration in sweat is a key indicator of hydration and muscle performance. Thin film materials, such as carbon nanotubes (CNTs) and ion-selective membranes (ISMs), have become central to the development of wearable sweat sensors. CNTs offer high mechanical flexibility and electrical conductivity, and ISMs enable non-invasive detection of specific ions in sweat.
Unfortunately, ...

A new study from Paris Nanterre University, Paris Cité University and the University of Southampton, published today [28 August] in Nature Human Behaviour, assessed 248 meta-analyses, including 200 clinical trials involving over 10,000 participants.
Researchers were investigating the efficacy and safety of complementary, alternative and integrative medicines (CAIMs) to treat autism. They looked at 19 types of treatment, including animal-assisted interventions, ...
New self-assembling material could be the key to recyclable EV batteries
2025-08-28
Today’s electric vehicle boom is tomorrow’s mountain of electronic waste. And while myriad efforts are underway to improve battery recycling, many EV batteries still end up in landfills.
A research team from MIT wants to help change that with a new kind of self-assembling battery material that quickly breaks apart when submerged in a simple organic liquid. In a new paper published in Nature Chemistry, the researchers showed the material can work as the electrolyte in a functioning, solid-state ...
An ancient signpost: Minute fossils tell big story about arthropod evolution
2025-08-28
A tiny fossil of a sea creature that lived more than half a billion years ago sheds new light on the evolution of arthropods, the most species-rich and successful group of animals to inhabit the Earth, according to a study published in Nature Communications. One of the last remaining enigmas surrounding arthropod evolution has been the split of the tree of life separating the two largest groups of arthropods: mandibulates, the group including insects, crustaceans, millipedes and centipedes; and chelicerates, the group that includes spiders, scorpions and their kin. New analyses of fossils of an extinct segmented creature known as Jiangfengia multisegmentalis reveal ...
Predictable structures in music synchronises blood pressure the most, and could be used to create personalized music-based cardiovascular therapies
2025-08-28
Key take-aways
New research shows that blood pressure, like heart rate and breathing, synchronises more to predictable phrase structures in music, which may improve the body’s baroreflex sensitivity, i.e. its ability to regulate blood pressure.
92 participants had their blood pressure continuously monitored while listening to nine out of 30 piano music tracks. The piece of music that had the most predictable phrase structures, and the biggest impact on blood pressure, was the English pianist Harold Bauer’s performance of Franz Liszt’s ...

Food for thought: Using food delivery services to provide rapid cardiac arrest response and potentially save lives
2025-08-28
Inspired by an urgent need to improve timely defibrillation for out-of-hospital cardiac arrests (OHCA) in dense urban settings, a team of investigators developed a simulation that explored the potential of leveraging an existing food delivery network in Taipei City, Taiwan, to help address this challenge. Their findings in the Canadian Journal of Cardiology, published by Elsevier, suggest that deploying food delivery riders to deliver defibrillation may reduce automated external defibrillator (AED) response times by approximately three minutes—about 50% faster than a traditional emergency medical system (EMS)—and might be particularly beneficial during peak ...
College drinking linked to poor academics, mental health for those around the drinker: Study
2025-08-28
By Paul Candon
PISCATAWAY, NJ – It’s well known that alcohol misuse can harm not only drinkers themselves but also those around them. Now, a new report in the Journal of Studies on Alcohol and Drugs shows that, among college students, harms such as lower grades, mental distress and even suicidal thoughts are linked to being exposed to a drinker’s poor behavior.
“We often think of alcohol’s harms as physical or social, but this was the first study to assess academic harms from others’ drinking, like having to drop a class or take on extra work,” says lead researcher Pamela ...
Nearly 80% of whale sharks in this marine tourism hotspot have human-caused scars
2025-08-28
Whale sharks, the largest living fish species, are classified as endangered on the IUCN Red List of Threatened Species. Over the past 75 years, populations have declined by more than 50% worldwide, and by up to 63% in the Indo-Pacific region. Because whale sharks take up to 30 years to become sexually mature, populations can only recover slowly from threats like hunting for fins, meat, and oil, habitat loss, and entanglement in fishing nets.
Now, an international group of researchers has shown that in the Bird’s Head Seascape off Indonesian West Papua, 62% of whale sharks have scars and injuries from preventable ...
Spider uses trapped fireflies as glowing bait to attract more prey
2025-08-28
Ecologists have observed a species of nocturnal spider attracting prey to its web using the bioluminescent beacons of already trapped fireflies. This rare example of a predator exploiting its prey’s mating signal for its own gain is documented in the British Ecological Society’s Journal of Animal Ecology.
Researchers at Tunghai University, Taiwan have observed sheet web spiders Psechrus clavis capturing fireflies in their webs and leaving them there while they emitted bioluminescent light for up to an hour. The researchers even observed the spiders going to check on the captured fireflies from time to time.
Intrigued ...
How AI can build bridges between nations, if diplomats use it wisely
2025-08-28
Dr Donald Kilburg, who was a member of the US Department of State, says the technology is already shaping work for the likes of embassy officials whose jobs are to protect their country’s interests abroad.
But the US army veteran and retired professor warns that algorithms cannot ‘read the room’, and can’t replicate the ‘empathy, intuition and deep cultural understanding’ of human diplomats.
He says: “AI can streamline diplomacy, but only humans bring the empathy and intuition that make negotiations ...

Birdwatching tourism is booming. Some countries are benefiting, while others are left behind
2025-08-28
Deep in a forest in the Andes, high atop a tall tree, there’s a quick, colorful flash of plumage in vivid shades of yellow, green, and blue. A high-pitched musical chirp rings out. Through a carefully trained pair of binoculars, a beautiful little bird comes into view. It’s a multicolored tanager, a species that lives only in the mountains of Colombia. Seeing it in person for the first time feels like the thrill of discovery. Watching it search for fruit across the treetops brings a sense of peace and connection to nature.
Experiences like these are what motivate birdwatchers to travel the globe, in hopes ...

2025-08-27
Contact: Gina DiGravio, 617-358-7838, ginad@bu.edu
(Boston)—Next to cancer recurrence or progression, cardiovascular diseases are the leading causes of death in cancer survivors. The Surveillance, Epidemiology, and End Results database revealed that among the more than three million who initially survived cancer between 1973 and 2012, 38% eventually succumbed to the disease while 11.3% died from cardiovascular diseases. Specifically, cancer survivors are at a four to seven-fold higher risk of venous thromboembolism ...
Risk of a second cancer after early breast cancer is low
2025-08-27
For women diagnosed with early breast cancer, the long-term risk of developing a second primary cancer is low (around 2-3% greater than women in the general population), finds a study published by The BMJ today.
The researchers say this information can help reassure many breast cancer survivors who believe their risk of a second primary cancer is much higher than these results suggest.
Breast cancer survivors are at increased risk of developing second primary cancers, but risk estimates from previous studies are inconsistent. ...
Genetic key to why immune responses differ between men and women
2025-08-27
A new study has uncovered a key difference between the immune system of males and females - and it comes down to a single gene.
It is known that biological sex affects the function of the immune system, with women often being more severely affected by autoimmune conditions or allergic diseases.
Scientists from the University of York have now identified the gene Malat1 as a critical player in regulating immune responses in female immune cells, but not in males.
The team studied T cells, a pillar of our immune system, in the lab and animal models of inflammation. ...
Discovery could lead to new treatments for life-threatening allergic reactions
2025-08-27
Food allergies affect more than half a billion people worldwide. In severe cases, even a small bite of the wrong food can trigger anaphylaxis — a rapid, body-wide allergic reaction that can cause difficulty breathing, a dangerous drop in blood pressure and even death.
Scientists have long understood how injected allergens — like those in lab tests or insect stings — trigger anaphylaxis. But researchers have puzzled over how anaphylaxis begins in the gut after eating a food allergen.
Now, Arizona State University researchers, in collaboration with a team ...
