Does red meat alter gut bacteria to aggravate inflammatory bowel disease?

2025-08-20
(Press-News.org) Epidemiological studies have revealed a strong correlation between red meat consumption and the development of inflammatory bowel disease. In a new study published in Molecular Nutrition and Food Research that was conducted in mice, red meat consumption caused an imbalance of bacteria in the intestinal microbiota. 

Investigators fed mice various kinds of red meat including pork, beef, and mutton for two weeks, and then they induced inflammation in the colon. Intake of these three red meat diets exacerbated colonic inflammation. Analyses revealed an overproduction of pro-inflammatory cytokines and infiltration of immune cells in the colon of mice fed red meat diets. 

These diets led to a marked decrease in the relative abundance of Streptococcus, Akkermansia, Faecalibacterium, and Lactococcus bacterial strains, coupled with an increase in Clostridium and Mucispirillum.  

“This study contributes to improving food innervation approaches for inflammatory bowel disease treatment and indicates a close crosstalk among diet, gut microbiota, and intestinal immunity,” said co–corresponding author Dan Tian, MD, PhD, of Capital Medical University, in China.

Does LGBTQ+ workplace inclusion impact a company’s environmental performance?

2025-08-20
An analysis in Business Strategy and the Environment reveals that among U.S. firms, those with stronger LGBTQ+ inclusion have higher environmental performance scores and greater renewable energy consumption.   In the analysis of 2010–2023 data on 898 firms, this relationship was partially mediated by environmental innovation, indicating that LGBTQ+ inclusive workplace practices enhance environmental outcomes by fostering innovation.   Investigators also found that firms headquartered in states that recognized same-sex marriage prior to the Obergefell v. Hodges case (which ruled that the fundamental right to marry is guaranteed ...

Should additional food allergens have mandatory labelling due to anaphylaxis risk?

2025-08-20
The European Regulation list on mandatory labelling of foods includes 14 allergenic foods. Research published in Clinical & Experimental Allergy has identified eight additional foods frequently involved in food-induced anaphylaxis.  The research was based on an analysis of food-induced anaphylaxis cases reported to the Allergy Vigilance Network from 2002–2023. Allergenic foods involved in ≥1% of cases and not included in the European Regulation list included goat’s and sheep’s milk (2.8% of cases), buckwheat (2.4%), peas and lentil (1.8%), alpha-gal (1.7%), pine nut (1.6%), kiwi (1.5%), beehive products (1.0%), and apple (1.0%).  Due ...

Will climate change promote the spread of Dengue fever through Western Europe?

2025-08-20
Most people recover from Dengue fever, which is caused by a virus transmitted from the Asian tiger mosquito, but some infected individuals experience serious bleeding, a sudden drop in blood pressure, and even death. Although Dengue fever has long been recognized as a disease of the tropics and sub-tropics, a study published in Global Change Biology reveals that it is likely to spread increasingly northward and through Western Europe as climate change expands the Asian tiger mosquito’s habitat.  The mosquito lays its eggs in water where, with sufficient temperature, larvae develop and give rise to flying bloodsucking adults. After ...

Sleep problems in early teens associated with future self-harm

2025-08-20
Self-harm in young people is a major public health concern, rates are rising, and the adolescent years presents a critical period of intervention. Another modern challenge facing adolescents is sleep deficiency, with global reductions in total sleep time and inconsistent sleep patterns, and as many as 70% of teenagers getting inadequate sleep.  Published today in the Journal of Child Psychology and Psychiatry, researchers at The University of Warwick and University of Birmingham have investigated this relationship between multiple measures of sleep problems and self-harm, using data from over 10,000 teenagers from the Millenium Cohort.  10,000 teenagers, ...

Supergiant star’s gigantic bubble surprises scientists

2025-08-20
Astronomers from Chalmers University of Technology, Sweden, have discovered a vast and expanding bubble of gas and dust surrounding a red supergiant star – the largest structure of its kind ever seen in the Milky Way. The bubble, which contains as much mass as the Sun, was blown out in a mysterious stellar eruption around 4000 years ago. Why the star survived such a powerful event is a puzzle, the scientists say. The new results are published in the scientific journal Astronomy and Astrophysics, and the team was led by Mark Siebert, Chalmers, Sweden. Using the ALMA radio telescope ...

Most known species evolved during 'explosions’ of diversity, shows first analysis across ‘tree of life’

2025-08-20
The British evolutionary biologist JBS Haldane is said to have quipped that any divine being evidently had ‘an ordinate fondness for beetles’. This bon mot conveyed an important truth: the ‘tree of life’ – the family tree of all species, living or extinct – is very uneven. In places, it resembles a dense thicket of short twigs; elsewhere it has only sparse but long branches. A few groups tend to predominate: as Haldane pointed out, more than 40% of extant insects are beetles, while 60% of birds ...

World Mosquito Day 2025: Europe sets new records for mosquito-borne diseases: ECDC supporting Member States in adapting to ‘new normal’

2025-08-20
Europe is experiencing longer and more intense transmission seasons for mosquito-borne diseases, including WNV infection and chikungunya virus disease. This shift is driven by climatic and environmental factors such as rising temperatures, longer summer seasons, milder winters and changes in rainfall patterns — conditions that combine to create a favourable environment for mosquitoes to thrive and transmit viruses. Pamela Rendi-Wagner, ECDC Director, said: 'Europe is entering a new phase — where longer, more widespread and more ...

Study finds coastal wetlands generate $90 million annually for Virginia communities

2025-08-20
A new study led by William & Mary’s Batten School & VIMS shows that tidal marshes, including both natural wetlands and man-made living shorelines, generate approximately $90 million annually in economic value for communities across Virginia’s Middle Peninsula. Published in the journal Nature-Based Solutions and funded by a grant from the National Oceanic and Atmospheric Administration's Chesapeake Bay Fisheries Research Program (NA21NMF4570524-T1–01), the study combined ecological data, spatial modeling, economic valuation and stakeholder ...

Study uncovers biological clues about daytime sleepiness

2025-08-20
Mass General Brigham researchers identified seven molecules in the blood linked to excessive daytime sleepiness, including factors related to diet and hormones. Approximately one in three Americans reports experiencing overwhelming drowsiness during the day—a condition known as excessive daytime sleepiness (EDS). EDS is linked to an increased risk of serious conditions such as cardiovascular disease, obesity, and diabetes. A new study led by investigators from Mass General Brigham and Beth ...

Study links teen vaping to increased risk of smoking and health issues

2025-08-20
Researchers have shown that there is strong evidence that e-cigarette use may act as a gateway to cigarette smoking and other health issues in young people. A review of reviews has revealed that there is a consistent link between e-cigarette use and later cigarette smoking, as well as potential links between vaping and a range of health issues, including asthma, mental health concerns, and drug use. Researchers, from the University of York and the London School of Hygiene and Tropical Medicine (LSHTM), argue that more research is needed to determine whether there is a direct cause and effect, but the consistency of the findings between the studies conducted ...
