Regular physical activity before cancer diagnosis may lower progression and death risks

2025-01-08
Regular physical activity before a cancer diagnosis may lower the risks of both disease progression and death, suggests research published online in the British Journal of Sports Medicine. And even relatively low levels of physical activity may be advantageous, the findings indicate. There is compelling evidence that physical activity has a key part to play in lowering the risk of death from cancer, but the evidence isn’t as conclusive for its role in disease progression, explain the researchers. To explore this further, they analysed anonymised data from the Discovery Health Medical Scheme (DHMS), linked to the Vitality health promotion programme. The DHMS is the ...

Basking too long in a sauna without adequate hydration may risk heat stroke, doctors warn

2025-01-08
Basking too long in a sauna may put bathers at risk of heat stroke, particularly if they haven’t drunk enough water beforehand, warn doctors in the journal BMJ Case Reports, after treating a woman whose condition required admission to hospital. Although relatively rare, heat stroke can be life threatening, even in the absence of various underlying risk factors, such as heart, lung, or neurological disease, and heavy drinking or taking a cocktail of prescription meds, they point out. Heat stroke is defined as a sharp increase in core body temperature above ...

Dinosaurs roamed the northern hemisphere millions of years earlier than previously thought, according to new analysis of the oldest North American fossils

Dinosaurs roamed the northern hemisphere millions of years earlier than previously thought, according to new analysis of the oldest North American fossils
2025-01-08
MADISON — How and when did dinosaurs first emerge and spread across the planet more than 200 million years ago? That question has for decades been a source of debate among paleontologists faced with fragmented fossil records. The mainstream view has held that the reptiles emerged on the southern portion of the ancient supercontinent Pangea called Gondwana millions of years before spreading to the northern half named Laurasia.             But now, a newly described dinosaur whose fossils were uncovered by University of Wisconsin–Madison paleontologists is challenging ...

Breakthrough Durham University research offers new insights into quenching electrical waves in the heart

2025-01-08
-With images-   Scientists at Durham University have developed a theoretical framework to predict the efficacy of quenching of electrical pulses in excitable media, such as those found in the human heart.   This breakthrough could significantly accelerate the development of more efficient defibrillation techniques for treating cardiac arrhythmias.   The study, published in Physical Review E, addresses a longstanding challenge in understanding how stable excitation waves in systems like cardiac tissue can be effectively neutralised through small changes.   These electrical waves, when irregular, are thought to underly serious conditions such as fibrillation, ...

Crop switching for climate change in China
2025-01-07
A study of Chinese agriculture recommends planting areas currently growing maize and rapeseed with alternative crops to reduce environmental costs while maximizing food production as the climate changes.  Chinese food production has nearly doubled since the 1980s, mainly thanks to intensified nutrient usage and irrigation. Given that China’s demand for food is forecast to increase further, Qi Guan and colleagues modeled the country’s agricultural system under varying climate change scenarios in the 21st century, using a dynamic global vegetation model. The authors created scenarios ...

Cell-based therapy improves outcomes in a pig model of heart attacks

Cell-based therapy improves outcomes in a pig model of heart attacks
2025-01-07
BIRMINGHAM, Ala. – In a large-animal model study, researchers have found that heart attack recovery is aided by injection of heart muscle cell spheroids derived from human induced pluripotent stem cells, or hiPSCs, that overexpress cyclin D2 and are knocked out for human leukocyte antigen classes I and II. This research, published in the journal Circulation Research, used a pig model of heart attacks. Pig hearts more closely resemble the human heart in size and physiology, and thus have a higher clinical relevance to human disease, compared to studies in mice. University of Alabama at Birmingham researchers, led by Jianyi “Jay” ...

Researchers have a better understanding of how our cells dispose of waste while developing ways to control it

Researchers have a better understanding of how our cells dispose of waste while developing ways to control it
2025-01-07
Recycling takes place in our cells at all times: in a process called autophagy, cell components that are no longer needed are enclosed by membranes and broken down into their basic building blocks. This vital process prevents the formation of harmful aggregates and makes nutrients available again. A research team co-led by Prof. Dr. Claudine Kraft from the CIBSS Cluster of Excellence at the University of Freiburg and Dr. Florian Wilfling from the Max Planck Institute of Biophysics in Frankfurt has now discovered the conditions necessary for autophagy to start. They were also able ...

Earth’s air war: Explaining the delayed rise of plants, animals on land
2025-01-07
New Haven, Conn. — If you like the smell of spring roses, the sounds of summer birdsong, and the colors of fall foliage, you have the stabilization of the ozone layer to thank for it. Located in the stratosphere, where it shields the Earth from harmful ultraviolet radiation, the ozone layer plays a key role in preserving the planet’s biodiversity. And now we may have a better idea of why that took so long — more than 2 billion years — to happen. According to a new, Yale-led study, ...

Typical cost of developing new pharmaceuticals is skewed by high-cost outliers

2025-01-07
The typical cost of developing new medications may not be as high as generally believed, with a few ultra-costly medications skewing public discussions about the cost of pharmaceutical research and development, according to a new RAND study.  Using a novel method to assess spending on research and development for 38 drugs that were recently approved by the U.S. Food and Drug Administration, researchers found that the mean, or average, cost of developing a new drug was much higher than the mid-point (median) cost of development.  Researchers estimated a median direct research and development cost of $150 million compared to a mean of $369 million.  Costs ...

Predicting the progression of autoimmune disease with AI

2025-01-07
HERSHEY, Pa. — Autoimmune diseases, where the immune system mistakenly attacks the body’s own healthy cells and tissues, often have a preclinical stage before diagnosis that’s characterized by mild symptoms or certain antibodies in the blood. However, in some people, these symptoms may resolve before culminating in the full disease stage. Knowing who may progress along the disease pathway is critical for early diagnosis and intervention, improved treatment and better disease management, according to a team led by researchers from the ...

Led by the UCLA Program for the Education and Enrichment of Relationship Skills (PEERS) Clinic, the new 20-week program aims to demystify the often complex social rules surrounding dating and help participants gain a deeper understanding of relationship dynamics “Romantic relationships can be transformative, but for many autistic adults, the path to connection can feel uncertain,” ...

Research Spotlight: Researchers reveal the influences behind timing of sleep spindle production

Research Spotlight: Researchers reveal the influences behind timing of sleep spindle production
2025-01-07
How would you summarize your study for a lay audience? Our research focuses on sleep spindles—short bursts of brain activity during sleep that are crucial for stabilizing sleep and supporting memory. Sleep spindles are of great interest because changes in spindle activity have been linked to many neurodevelopmental and neurodegenerative disorders, such as Alzheimer’s disease and autism. While many factors influence when and how these spindles occur, such as sleep stages or brain rhythms, we discovered that short-term patterns, like a musical rhythm spanning just a few seconds, play the most ...

New research reveals groundwater pathways across continent

New research reveals groundwater pathways across continent
2025-01-07
Researchers from Princeton University and the University of Arizona have created a simulation that maps underground water on a continental scale. The result of three years’ work studying groundwater from coast to coast, the findings plot the unseen path that each raindrop or melted snowflake takes before reemerging in freshwater streams, following water from land surface to depths far below and back up again, emerging up to 100 miles away, after spending from 10 to 100,000 years underground. The simulation, published Jan. 6 in the journal Nature Water, shows that rainfall and snowmelt ...
