Vitamin D levels during pregnancy and dental caries in offspring

JAMA Network Open

2025-12-02

(Press-News.org) About The Study: In this cohort study, maternal plasma 25-hydroxyvitamin D levels throughout pregnancy were inversely associated with odds of offspring early childhood caries. These findings support the potential benefit of vitamin D supplementation before or during pregnancy in reducing the risk and severity of childhood dental caries.

For those living with dementia, new study suggests shingles vaccine could slow the disease

2025-12-02

An unusual public health policy in Wales may have produced the strongest evidence yet that a vaccine can reduce the risk of dementia. In a new study led by Stanford Medicine, researchers analyzing the health records of Welsh older adults discovered that those who received the shingles vaccine were 20% less likely to develop dementia over the next seven years than those who did not receive the vaccine. The remarkable findings, published April 2 in Nature, support an emerging theory that viruses that affect the nervous system can increase the risk of dementia. If further ...

Your pain meds' side effects may be masquerading as heart failure

2025-12-02

Clinicians may fail to recognize common side effects of drugs like gabapentin — which are frequently prescribed for nerve pain — leading them to prescribe unnecessary medications that cause yet more side effects. This phenomenon, known as a “prescribing cascade,” is increasingly seen as a danger to older patients. In this case, gabapentinoids — which include gabapentin (Neurontin) and pregabalin (Lyrica) — may cause leg swelling, leading doctors to suspect heart failure and then prescribe diuretics that can cause kidney injury, light headedness, and falls. Researchers tracked the ...

Carbon monoxide, the ‘silent killer,’ becomes a boon for fuel cell catalysts

2025-12-02

Researchers Dr. Gu-Gon Park, Dr. Yongmin Kwon, and Dr. Eunjik Lee from the Hydrogen Fuel Cell Laboratory at the Korea Institute of Energy Research (President Yi Chang-Keun, hereafter “KIER”) have developed a technology that uses carbon monoxide, typically harmful to humans, to precisely control metal thin films at a thickness of 0.3 nanometers. This technology enables faster and simpler production of core–shell catalysts, a key factor in improving the economic viability of fuel cells, and is expected to significantly boost related industries. Core–shell catalysts refer to catalysts in which the inner core and outer shell are made of different metals. ...

Historical geography helps researchers solve 2,700-year old eclipse mystery

2025-12-02

An international team of researchers has used knowledge of historical geography to reexamine the earliest datable total solar eclipse record known to the scientific community, enabling accurate measurements of Earth's variable rotation speed from 709 BCE. The researchers calculated how the Sun would have appeared from Qufu, the ancient Chinese capital of the Lu Duchy, during the total solar eclipse. Using this information, they analyzed the ancient description of what has been considered the solar corona—the ...

SwRI expands High-Viscosity Flow Loop to test equipment moving heavy oils

2025-12-02

SAN ANTONIO — December 2, 2025 — Southwest Research Institute (SwRI) has upgraded its High-Viscosity Flow Loop (HVFL) to meet increased demands in the oil and gas industry. The expanded and upgraded facility now enables SwRI to offer more comprehensive, efficient, and cost-effective heavy oil testing. Increasing production of heavy oil around the world led SwRI to develop the HVFL in 2015 to gain a better understanding of flow equipment performance in extremely viscous conditions. “Today, as operators tap into reservoirs with higher gas volume fractions, conventional pumping systems struggle to process the volatile mixture of gas and liquid, demanding ...

Insilico Medicine and Atossa Therapeutics publish AI-driven study in Nature's Scientific Reports identifying (Z)-endoxifen as a potential therapeutic candidate for glioblastoma

2025-12-02

Cambridge, MA — 12/02/2025 — Insilico Medicine (“Insilico”), a global leader in AI-powered drug discovery, and Atossa Therapeutics (“Atossa”) (Nasdaq: ATOS), a clinical-stage biopharmaceutical company developing novel treatments for breast cancer and other serious conditions, announce the publication of a joint study evaluating the potential of (Z)-endoxifen for glioblastoma multiforme (GBM). The peer-reviewed article, now published in Nature’s Scientific Reports, represents one of the most comprehensive AI-enabled analyses to date exploring whether endoxifen, an active metabolite of tamoxifen ...

An overlooked hormone eyed as deadly driver of postmenopausal breast cancer in women with obesity

2025-12-02

WASHINGTON – A new analysis of research into the most common type of breast cancer has zeroed in on an overlooked hormone that may be responsible for the increased risk of breast cancer death in post-menopausal women with obesity. It also raises the possibility that treatment of these aggressive breast cancers could be improved with addition of weight-loss drugs known as GLP-1 receptor agonists. The most common and deadly form of this disease in women after menopauses is estrogen receptor positive (ER+) breast cancer. According to Joyce Slingerland, ...

Study links childhood vaccination to lower risk of drug-resistant bacteria

2025-12-02

PULLMAN, Wash. – Children in Guatemala who received a common vaccine that helps prevent pneumonia were less likely to carry antibiotic-resistant bacteria, according to a new study led by Washington State University researchers. The team examined whether rotavirus (RV) and pneumococcal (PCV13) vaccines reduce gut colonization by a group of bacteria that includes Escherichia coli and resists critical antibiotics used to treat severe infections. Colonization occurs when the bacteria are present in the body, often in the gut, without causing illness, yet they can persist and later cause infections or spread to others. While rotavirus ...

LLMs choose friends and colleagues like people

2025-12-02

When large language models (LLMs) make decisions about networking and friendship, the models tend to act like people, across both synthetic simulations and real-world network contexts. Marios Papachristou and Yuan Yuan developed a framework to study network formation behaviors of multiple LLM agents and compared these behaviors against human behaviors. The authors conducted simulations using several large language models placed in a network, which were asked to choose which other nodes to connect with, given their number of connections, common neighbors, and shared attributes, ...

Gas stoves and nitrogen dioxide exposure

2025-12-02

Twenty-two million Americans would no longer be breathing in unhealthy levels of nitrogen dioxide if they switched from gas and propane stoves to electric stoves. Robert Jackson and colleagues combined outdoor air quality data with estimates of indoor nitrogen dioxide emissions from stoves in more than fifteen cities. As outdoor air quality improves, stoves become an increasingly important source of exposure. According to the World Health Organization, health risks to the respiratory system increase at levels above ...
