High-fat diets in mouse parents alter offspring brain development

Researchers fed breeding pairs of mice five diets with different fat and sugar contents to examine how parental nutrition affects offspring brain development. High-fat diets, alone or combined with high sugar, delayed early motor development and altered brain structure in young adult offspring, while the high-sugar-only diet produced no significant changes in individual brain regions after correction for multiple comparisons.

Ketones may change sleep patterns, but not always for the better

Researchers reviewed animal and human studies and found that ketone bodies may affect sleep stages through energy metabolism and cellular signaling, with the clearest direct evidence involving acetoacetate in mice. They reported mixed human findings and called for controlled studies to separate ketone-specific effects from changes linked to diet, disease, circadian timing, and physiological stress.

Plant and animal proteins show opposite effects on testosterone levels

Higher animal protein intake was associated with lower blood testosterone levels, while higher plant protein intake was associated with higher levels, according to a new study from the University of Eastern Finland.

Ulcerative colitis burden across 7MM to exceed 2.36 million cases by 2035, forecasts GlobalData

The diagnosed prevalent cases of ulcerative colitis (UC) in the seven major markets (7MM) are projected to reach over 2.36 million by 2035.

Climate change intensifies global health risks, Lancet Countdown report warns

The 2026 Report of the Lancet Countdown on Health and Climate Change finds that many of the health risks and harms of climate change grew faster in the decade since the Paris Agreement was introduced (2016–2025) than in the decade before it (2006–2015).

Low vitamin B12 is linked to heart disease. Supplements tell a different story

A narrative review published in Nutrition Journal examines how vitamin B12 deficiency may contribute to cardiovascular disease through elevated homocysteine, endothelial dysfunction, oxidative stress and altered methylation. The authors found that B12 supplementation has not consistently prevented heart attacks or cardiovascular deaths in clinical trials, although combined B-vitamin therapy may modestly reduce stroke risk, particularly in populations without folic acid fortification.

CT scans linked vitamin D levels to fat within muscles after bariatric surgery

Researchers followed 113 adults for one year after bariatric surgery and found that those with higher postoperative vitamin D concentrations had less fat infiltration within certain muscles and lower visceral adiposity. They found no significant association between increases in vitamin D and changes in body composition after correction for multiple comparisons, while preoperative vitamin D levels did not independently predict postoperative body composition.

Amyloid fibers help sperm deliver RNA to mouse embryos

Researchers identified RNA-associated amyloid fibrils in human seminal fluid and demonstrated that synthetic PAP fibrils could enter mammalian sperm. In mouse IVF experiments, these fibrils helped sperm deliver RNA to embryos, where the detected reporter-protein signal was at least tenfold higher than without fibril exposure.

Non-drug and non-surgical low back pain treatments are highly cost-effective options

Non-drug and non-surgical treatments for low back pain, including psychological support, exercise and self-management strategies are cost-effective interventions, according to a study published October 27th in the open access journal PLOS Medicine by Manuela Loureiro Ferreira from the George Institute for Global Health, Australia, and colleagues.

Endometrial cancer rates rise sharply among younger South Texas women

An Upper-South region of Texas including San Antonio and Bexar County had the state's highest hysterectomy-corrected incidence of endometrial cancer and the largest increase over time, a study led by scientists at The University of Texas at San Antonio Health Science Center and the National Cancer Institute showed.

High intake of saturated fat can promote favorable changes in cardiovascular risk markers

New analyses from the Norwegian randomized controlled trial CARBFUNC show that more than doubling saturated fat intake over a two-year period can promote favorable changes in several cardiovascular risk markers, without increasing apoB, the main suspected risk factor.

Could a few days of annual extreme heat raise dementia risk?

Extreme outdoor heat is associated with higher dementia risk, especially in socially vulnerable areas, emphasizing the need for targeted community strategies.

Semaglutide changes gut bacteria in rats beyond what eating less explains

Researchers compared semaglutide-treated male and female rats with pair-fed animals receiving the same amount and type of food to distinguish drug-associated microbiome changes from those linked to reduced eating. Semaglutide altered bacterial richness and community composition, with some changes absent from the pair-fed groups and uncertain consequences for health.

Beer and liquor show more oral bacteria links than wine in a large US study

Researchers analyzed beverage intake and oral microbiome data from 5,598 adults across three US cohorts and found that alcohol consumption showed the strongest associations with oral bacterial diversity and composition among the beverages examined. Higher alcohol intake was associated with greater bacterial richness and differences in genera linked to oral health, but the cross-sectional preprint could not establish whether alcohol caused these differences or influenced disease risk.

New report urges unified lifecycle approach to women's heart health

A new approach to women's heart health may offer them a lifetime of opportunities. A trio of scientific papers, published today in the journal Circulation, spells out how fluctuating hormones, mental health and well-being, the heart and the brain are linked and how those connections need to be a routine part of care from a young age.

Beer, wine or spirits: A large study finds different mortality patterns for each

Researchers analyzed data from 340,924 UK Biobank participants and found that high total alcohol consumption was associated with greater all-cause, cardiovascular, and cancer mortality, while moderate consumption was linked to increased cancer mortality. Beer/cider and spirits showed associations with higher mortality across several outcomes, whereas low-to-moderate wine consumption was linked to lower mortality for certain outcomes, though the observational study cannot establish causation.

Non-dairy creamer drives up calorie count in coffee cups

While Americans have been drinking roughly the same amount of coffee over recent years, the calories in those cups have increased thanks primarily to the addition of non-dairy creamer, according to a new study from researchers at the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University.
