Air conditioning in nursing homes and mortality during extreme heat

JAMA Internal Medicine

2025-12-15

(Press-News.org) About The Study: In this case-crossover study, mortality was lower during extreme heat days in nursing homes with air conditioning (AC) compared to those without AC. These findings suggest that AC provision in nursing homes and other congregate care settings may be important for preventing mortality among older adults during extreme heat days.

The Alps to lose a record number of glaciers in the next decade

2025-12-15

In brief: In a groundbreaking study, an international team led by ETH Zurich researchers has for the first time calculated how many glaciers worldwide are likely to remain until the end of the century and for how long. Depending on how sharply the planet warms, the study shows that in a scenario with a global temperature rise of +4.0 °C, only about 18,000 glaciers would remain, whereas at +1.5 °C there would be around 100,000. The researchers coined the term, “Peak Glacier Extinction”, the point when annual glacier loss hits its maximum. At +1.5 °C it occurs around 2041 with 2,000 glaciers lost; at +4 °C ...

What makes a good proton conductor?

2025-12-15

A number of advanced energy technologies — including fuel cells, electrolyzers, and an emerging class of low-power electronics — use protons as the key charge carrier. Whether or not these devices will be widely adopted hinges, in part, on how efficiently they can move protons. One class of materials known as metal oxides has shown promise in conducting protons at temperatures above 400 degrees Celsius. But researchers have struggled to find the best materials to increase the proton conductivity at lower temperatures and improve efficiency. Now, MIT researchers have developed a physical model to predict proton mobility across a wide range of metal ...

New science reporting guide published for journalists in Bulgaria

2025-12-15

A new guide aimed at helping aspiring science journalists in Bulgaria to cover scientific topics has been published. ‘First steps in science journalism – a practical experience guide’ (Първи стъпки в научната журналистика – практически насоки от опит) was written by three experienced science reporters from Bulgaria, who provide helpful insights from their own experiences and examples of stories they have reported over the years for online, ...

New international study reveals major survival gaps among children with cancer

2025-12-15

Every year, more than 200,000 children under the age of 15 are diagnosed with cancer worldwide, and nearly 75,000 die from the disease. Most of these deaths occur in Africa, Asia, and Latin America, even though childhood cancer is more common in Europe and North America. In high-income countries, over 80% of children survive, while the global average is just 37%. Why is the gap so large? Striking differences An international study using data from the International Agency for Research on Cancer (IARC), analyzed data from nearly 17,000 children in 23 countries ...

It was written by the science journalist and academic Dr. Gülsen Saray, and reviewed by editors and academics Prof. Dr. Akif Özer and Prof. Dr. Sefa Yüce. The ...

Scientists develop a smarter mRNA therapy that knows which cells to target

2025-12-15

[New York, NY [December 15, 2025] — Researchers at the Icahn School of Medicine at Mount Sinai have developed a first-of-its-kind mRNA system that switches on therapeutic genes preferentially inside targeted cells—an advance demonstrated in studies in mice that could lay the groundwork for safer, more precise treatments for cancer and other diseases. The system, called the cell-selective modRNA translation system (cSMRTS), is an engineered form of mRNA designed to activate in specific cell populations. ...

Neuroanatomy-informed brain–machine hybrid intelligence for robust acoustic target detection

2025-12-15

“Current automated STD methods perform well under controlled conditions but degrade sharply in low SNR or with unseen targets, while standalone BCI systems suffer from high false alarm rates. To overcome these limitations, we proposed a hybrid approach that combines the complementary strengths of neural perception and acoustic feature learning,” explained study author Luzheng Bi, a researcher at the Beijing Institute of Technology. The core innovations include (a) Tri-SDANet, an EEG decoding model incorporating neuroanatomical priors from source analysis, (b) a confidence-driven fusion strategy ...

Eight SwRI hydrogen projects funded by ENERGYWERX

The Lundquist Institute and its start-up company Vitalex Biosciences Announces Strategic Advancement of Second-Generation fungal Vaccine VXV-01 through Phase 1 Trials under $40 Million Competitive Con

2025-12-15

The Lundquist Institute (TLI) and its start-up company Vitalex Biosciences (Vitalex) are pleased to announce that the second-generation fungal vaccine candidate known as VXV‑01, which was developed using a proprietary TLI vaccine technology platform, is poised to move forward in development up to and including Phase 1 clinical evaluation — enabled by a major contract awarded to a collaboration consortium of Vitalex and Appili Therapeutics (TSX: APLI; OTCPink: APLIF). The contract from the National Institute of Health’s (NIH) National Institute of Allergy and Infectious Diseases (NIAID) is valued at up to US $40 million. It will support ...

Fine particles in pollution are associated with early signs of autoimmune disease

2025-12-15

A new study has linked air pollution exposure and immune-system changes that often precede the onset of autoimmune diseases. McGill University researchers analyzing Ontario data found that fine particles in air pollution are associated with higher levels of a biomarker linked with autoimmune diseases, such as systemic lupus. “These results point us in a new direction for understanding how air pollution might trigger immune system changes that are associated with autoimmune disease,” said Dr. Sasha Bernatsky, a James McGill Professor ...
