Cumulative anticholinergic exposure and change in gait speed and grip strength in older adults

JAMA Network Open

2025-07-10
(Press-News.org) About The Study: In this cohort study, higher anticholinergic exposure was associated with accelerated decline in physical performance, consistent with clinically meaningful decline. These findings suggest that minimizing anticholinergic medications is important for healthy aging.

Study suggests lemurs age differently than humans

2025-07-10
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 ...

Hypothermia alters glucose metabolism and may reveal mechanisms of metabolic disease

2025-07-10
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 ...

Content or form? The two possible paths of our memories

2025-07-10
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 ...

Research team produces low-loss spin waveguide network

2025-07-10
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 ...

PolyU-led research reveals that sensory and motor inputs help large language models represent complex concepts

2025-07-10
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 ...

Premature babies should have early skin-to-skin contact with their mother

2025-07-10
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 ...

New research in JNCCN offers reassurance about localized prostate cancer prognosis

2025-07-10
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 ...

Fluorinated polyimide: High toughness and low dielectric properties pave new path for high-frequency communication materials

2025-07-10
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 ...

Radar-based control of a helical microswimmer in 3-Dimensional space with dynamic obstacles

2025-07-10
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 ...

Short-term physical activity reduces metabolic-associated steatohepatitis by promoting the degradation of branched-chain amino acids in skeletal muscle

2025-07-10
Background and Aims Metabolic-associated steatohepatitis (MASH) is an advanced and progressive liver disease that potentially causes cirrhosis and hepatocellular carcinoma. Exercise is a crucial and effective intervention for ameliorating metabolic dysfunction-associated steatotic liver disease. This study aimed to provide a comprehensive understanding of the underlying mechanisms of MASH, which benefit a broad spectrum of MASH patients, including those who have difficulty engaging in physical activity. Methods We established a mouse model of MASH and selectively knocked down ...
