What can lemurs tell us about inflammation and aging, aka “inflammaging” in humans? That’s the question Elaine Guevara, a biological anthropologist who studies the evolution of life history and aging in primates, set out to understand. In newly published research on age-related inflammation in ring-tailed and sifaka lemurs, Guevara discovered that perhaps we should rethink the inevitability of inflammaging in humans. Although similar in many ways, ring-tailed and sifaka lemurs show differences in life pacing ...

Some mammals are capable of hibernating during periods of low food availability in an effort to conserve energy and survive. While it is easy to understand why species have evolved this survival mechanism, exactly how these animals regulate their metabolism and body temperature remains a mystery. Researchers have known for decades that the lower body temperatures observed during hibernation go hand in hand with lower metabolism. The metabolism of glucose, a sugar commonly used to generate the energy used by cells, produces heat, and maintaining lower body ...

If memories are the black box of our past, they can also shed light on the present by giving meaning to new situations. But how does memory retrieve either surface matches (based on same places, same people) or deeper, more conceptual ones (based on similar intentions or actions)? A team from the University of Geneva (UNIGE) has shed light on this question, showing that memory tends to favour the substance of a situation —its concept or underlying problem — when it can be linked to familiar mental ...

The rapid rise in AI applications has placed increasingly heavy demands on our energy infrastructure. All the more reason to find energy-saving solutions for AI hardware. One promising idea is the use of so-called spin waves to process information. A team from the Universities of Münster and Heidelberg (Germany) led by physicist Prof. Rudolf Bratschitsch (Münster) has now developed a new way to produce waveguides in which the spin waves can propagate particularly far. They have thus created the largest spin waveguide network to date. Furthermore, the group succeeded in specifically controlling the ...

Can one truly understand what “flower” means without smelling a rose, touching a daisy or walking through a field of wildflowers? This question is at the core of a rich debate in philosophy and cognitive science. While embodied cognition theorists argue that physical, sensory experience is essential to concept formation, studies of the rapidly evolving large language models (LLMs)suggest that language alone can build deep, meaningful representations of the world. By exploring the similarities between LLMs and human representations, researchers at The Hong ...

More premature babies who had early skin-to-skin contact with their mother were being breastfed at the time of discharge from hospital and for up to one year afterwards. However, this is far from the only benefit. A team from St. Olavs Hospital and the Norwegian University of Science and Technology (NTNU) have looked at this issue in a number of articles. They now hope that more hospitals will change their practice so that premature babies are not separated from their mother during the first few hours after birth. “The first few ...

PLYMOUTH MEETING, PA [July 10, 2025] — New research in the July 2025 issue of JNCCN—Journal of the National Comprehensive Cancer Network finds that for people diagnosed with nonmetastatic low-risk prostate cancer later in life, and treated according to NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®), 90% were likely to survive their cancer for their remaining life-expectancy. Of those with nonmetastatic higher-risk cancer and a longer life expectancy, that likelihood was still greater than 65%. The researchers studied 62,839 people diagnosed with non-metastatic prostate ...

Conventional polyimides (PIs) exhibit excellent thermal stability and mechanical performance, yet their dielectric properties (dielectric constant (Dk) > 3.2, dissipation factor (Df) > 0.005 @ 10 GHz). In previous reports, the introduction of trifluoromethyl reduced the dielectric constant and dissipation factor, but it increased chain rigidity, weakened hydrogen bonds interaction, and reduced free volume, which definitely reduced mechanical performance (such as poor toughness leading to crack risks in advanced packaging). Therefore, it is necessary to design PI materials with high toughness and low dielectric properties to meet ...

Recent advances have yielded significant progress in actuation, navigation, and control of magnetic microrobots. Nevertheless, dynamic obstacle avoidance in 3D environments remains a critical challenge, often relying on computationally intensive path-planning methods that limit real-time performance. "Using a hierarchical radar system to enable high-frequency direction updates minimizes computational load while ensuring collision-free navigation," explained corresponding author Jiangfan Yu, a professor at The Chinese University of Hong Kong, Shenzhen. The radar framework comprises (a) a motion sphere for directional ...

COLUMBUS, Ohio – If you find yourself routinely throwing away groceries and leftovers the night before you check out of an Airbnb, you’re not alone: A new study values the food wasted by U.S. vacation renters at about $2 billion each year. Based on survey results, researchers estimated that groceries, takeout and restaurant leftovers averaging $12 in value per night of short-term lodging remains uneaten. Though the analysis didn’t pinpoint how much remaining food landed in the trash, that was the most common outcome reported, along with taking food home or leaving it behind. On average, ...

When learning a second language (L2), many are likely familiar with the challenge of memorizing vocabulary, only to struggle with recalling and using it fluently in speech. Studies have found that speaking fluently in L2 depends not only on knowing what words mean but also on how quickly and automatically you can access and use them appropriately in contexts. This ability to retrieve contextually appropriate word meanings without conscious effort is known as automatized vocabulary knowledge (AVK). In a new study, a team of researchers led by Mr. Kotaro Takizawa from Waseda University, Japan, along with Prof. Kazuya Saito and Dr. ...

The term ‘oral health’ refers to the health of the mouth, teeth, gums, and other related structures, and it is closely linked with our well-being and quality of life. Recently, there has been a lot of interest in understanding how oral health is linked to and influences our overall health. For example, it was found that gum disease may be associated with various diseases such as diabetes and kidney disease. Poor oral health can also affect a person’s diet, which further increases a person’s ...

WESTMINSTER, Colorado – 10 July 2025 – New research from the University of Waterloo shows that a single, targeted herbicide application from a Remotely Piloted Aircraft System (RPAS) can suppress common reed invasions with more than 99% effectiveness. This result is among many research findings recently published online in Invasive Plant Science and Management (IPSM), volume 18, 2025, by Cambridge University Press, a Weed Science Society of America (WSSA) research journal. “The 99% reduction in live common reed stems observed with RPAS-based herbicide application demonstrates its capacity to suppress invasive common reed effectively,” says Rebecca ...

China is outstripping the rest of the world in artificial intelligence research at a time when AI is becoming a “strategic asset” akin to energy or military capability, according to a new report released today by research technology company Digital Science. The report – entitled DeepSeek and the New Geopolitics of AI: China’s ascent to research pre-eminence in AI – has been authored by Digital Science CEO Dr Daniel Hook based on data from Dimensions, the world’s largest and most comprehensive database describing the global research ...

Findings contradict previous health advice that children are more susceptible than adults to dehydration and hyperthermia in extreme temperatures But children are still at increased clinical risk due to being more physically active and less aware of the need to drink fluids  New research from the University of Sydney has found that children are at a similar risk of dehydration and hyperthermia in extreme heat as adults, contradicting previous advice that children are more susceptible to heat-related illnesses.  The study, published in the British ...

REDWOOD CITY, Calif. — July 10, 2025 — Today, the Chan Zuckerberg Initiative (CZI) announced its latest AI model aimed at helping researchers better understand how cells behave by focusing on the key networks that control cell behavior, making complex biological problems, like cancer, easier to solve.  The model, GREmLN (Gene Regulatory Embedding-based Large Neural model), is a milestone in CZI’s grand challenge to build a family of AI biomodels that predict and understand how cells work at every level — from molecules to ...

A new process could help to treat liver disease without needing an organ transplant, a new study reveals. Hepatic progenitor cells (HPCs) can help to repair the liver, but they often don’t stick well to the existing tissue, making treatment less effective. Scientists at the University of Birmingham have now developed a method to coat HPCs with natural sugars (polysaccharides) – such as hyaluronic acid and alginate – making the cells ‘stickier’. The coated cells showed a significant increase ...

Children with multiple long-term health issues undergo severe emotional stress at the same time as they are trying to cope with the physical challenges of their condition, a study has found. Research led by the University of Plymouth used AI language models to analyse sentiments and emotions expressed by almost 400 paediatric patients and their caregivers on social media. In particular, they wanted to assess young people’s opinions regarding their care and experiences during the COVID-19 pandemic, and the impact that had on their emotional and psychological wellbeing. Using anonymous data sourced from the Care Opinion platform they found that of the narratives analysed, almost ...

[Vienna, July 10, 2025] – Do you think you know which species are most vulnerable in an ecosystem? A novel analytical method developed by Italian physicists at the Complexity Science Hub (CSH) suggests there's more to discover. In their recent study, they found out how species like lizards and rabbits in South Florida's cypress wetlands are among their ecosystem's most at-risk species, pointing to vulnerabilities that aren't always obvious. The study, published in Chaos, Solitons & Fractals, introduces an innovative tool to map and measure species' ecological roles and vulnerabilities. ...

Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing reliable quantum technologies. By shining a single, carefully tuned laser beam on a gas of atoms, they managed to keep the atoms' internal spins synchronized, dramatically reducing the rate at which information is lost. In quantum sensors and memory systems, atoms often lose their magnetic orientation—or "spin"—when they collide with each other or the walls of their ...

When we’re taking antibiotics, some of the dose is excreted with urine and feces and ends up in our wastewater. The presence of this low dose of antibiotic creates an opportunity for resistant bacteria to evolve. Scientists studying antibiotic resistant bacteria in wastewater at a treatment plant discovered multi-drug resistant strains of bacteria species which are usually not dangerous to healthy people, but which could transmit genes for antibiotic resistance to much more dangerous bacteria like E. coli.   The scientists then challenged the bacteria with natural compounds which could potentially be included in wastewater treatment to kill off bacteria and fight ...
