Macrophages formed in the bone marrow can only assume the function of embryonal phagocytes, or "scavenger cells," to a certain degree according to a study by the University of Bonn and the Peter Doherty Institute for Infection and Immunity at the University of Melbourne.

A study of almost 61,000 women in Denmark, published in the journal JAMA Network Open, finds that women who had an overweight or obesity body mass index (BMI) trajectory during childhood were less likely to have children than women with a normal (average) BMI trajectory, and this effect on childlessness was already apparent in their mid-20s.

A new study co-led by Prof. Valeriya Malysheva, group leader at the VIB-UAntwerp Center for Molecular Neurology, has been published in Nature Genetics.

Working from home is often seen as a good solution for new mothers, but a new Washington State University study reveals that the blurred boundaries between home and work can introduce barriers to sustained breastfeeding.

Insilico Medicine ("Insilico"), a clinical-stage generative artificial intelligence (AI)-driven biotechnology company, today announced the publication of a collaborative study in the journal npj Precision Oncology.

In everyday life, the ability to read facial expressions plays a vital role in social communication, as it reveals a speaker's underlying emotions, intentions, and psychological state.

Human norovirus is the leading cause of acute gastroenteritis worldwide and is estimated to infect 600–700 million people each year.

A cat-training program for children with developmental disabilities fostered healthy child behaviors, strengthened relationships between children and their family cats and improved cats' social behavior, a new study found.

The Asian longhorned tick, Haemaphysalis longicornis, spreads serious pathogens, including severe fever with thrombocytopenia syndrome (SFTS) virus, Rickettsia, and Theileria, and its bite can cause a meat allergy in humans.

How can Alzheimer's research be made faster, better, and more effective? After decades of intensive research worldwide and despite recent therapeutic advances, scientists have not managed to fully arrest the progress of the disease.

In a mouse model, LMU researchers have discovered a signaling pathway through which diet influences the development of the immune system.

DNA Script, a pioneer in DNA synthesis providing scientists with rapid, on-demand access to high-quality DNA, today announced that in collaboration with prime awardee GE HealthCare, they have been awarded up to $26 million in funding for a four-year initiative from the Advanced Research Projects Agency for Health (ARPA-H).

Hallucinations and delusions that appear for the first time in midlife or later are often treated as psychiatric symptoms whose biological cause is unclear.

Obesity has been linked to skeletal muscle loss and deterioration. While M2 macrophages may play a role in regulating muscle function, the underlying mechanisms remain poorly understood.

An Australian-first study of twins will seek to find out why two genetically similar people respond differently to infections, diseases and treatments.

Researchers at Nagoya University in Japan have created an innovative treatment for periodontitis that targets and eliminates harmful bacteria while preserving beneficial oral microbes essential for health.

The review suggests that patient-reported “taste changes” during GLP-1RA treatment may reflect reduced food enjoyment and motivation rather than consistent impairment of basic taste. The authors propose a sensory-liking-wanting framework while emphasizing that current human evidence remains heterogeneous and largely indirect.

Researchers showed that airplane wastewater from a shared US-UK transatlantic route could be collected and analyzed to detect respiratory and enteric pathogen genetic material. The pilot also captured SARS-CoV-2 lineage patterns, including earlier detection of XEC on UK-origin flights, while showing the need for harmonized assays and broader sampling.

Researchers studying 188 adults aged 85 years or older with type 2 diabetes found the lowest serum 25(OH)D concentrations among those with both depressive symptoms and mild cognitive impairment. Lower levels remained associated with having both conditions after adjustment for selected factors, but the cross-sectional study cannot establish causation or a benefit from supplementation.

Calling a friend after a long day. Showing up to a neighbor's dinner when you'd rather stay home. Lingering a little longer in a conversation that didn't need to last.
