Scientists map protective cell networks hiding dormant breast tumor cells

Researchers at the MRC Laboratory of Medical Sciences (LMS), Imperial College London and UCL Genetics Institute have created a detailed map of cells within breast tumors and identified distinct neighborhoods of proliferating and dormant cells.

ESCRT-III proteins play an unexpected role in protecting DNA bridges during cell division

Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as DNA bridges that connect the two newly formed cells.

How intensive poultry farming accelerated the evolution of Campylobacter

Intensive poultry farming transforms Campylobacter jejuni ecology, enhancing host adaptability and raising concerns for foodborne illness transmission.

Pork supply chains may be shaping the global spread of drug-resistant Salmonella

Researchers linked 129,136 global human and swine Salmonella genomes with sampling from a Guangdong pork supply chain to examine how downstream stages relate to antimicrobial resistance. The study suggests slaughterhouse and retail interfaces may concentrate S. 4,[5],12:i:- ST34, resistant strains, and mobile resistance elements, supporting broader One Health surveillance beyond farms.

Biotherapeutic metabolite repairs gut damage caused by HIV infection

Researchers at the UC Davis School of Medicine have identified a naturally occurring metabolite that repairs gut damage caused by HIV infection and significantly improves the effectiveness of antiretroviral therapy (ART) in the nonhuman primate model of HIV/AIDS.

New computational technique traces ghost ancestry in modern human genomes

UC Berkeley researchers have identified regions of DNA that humans inherited from two unknown ancestors as a result of long-ago interbreeding among modern humans and at least four other archaic human relatives.

Landmark study identifies new genetic risk factors linked to fibromyalgia syndrome

In a landmark study published in Nature Medicine, an international team of researchers has identified new genetic risk factors associated with fibromyalgia syndrome.

Taste preference genes drive overeating and metabolic disease risk

Ever wonder why some people crave sweets while others can take them or leave them? Preliminary findings from a new study suggest that people who carry certain genetic variants associated with a preference for sweet or fatty tastes not only tend to eat more of these foods but also have a higher risk of obesity and type 2 diabetes as a result.

Genetic factors influence cholesterol response to low-carb diets

Can a low-carb diet cause your cholesterol to skyrocket? This question has vexed researchers and influencers alike as the popularity of low-carbohydrate diets has surged, yet the evidence has remained mixed.

Study links inherited genetics to cancer susceptibility and progression

Scientists have found the first direct evidence of the powerful role our genetic makeup plays in influencing our risk of cancer, with inherited genes interacting with acquired genetic mutations to shape how tumors evolve.

Wild bird surveillance reveals how H5Nx flu keeps returning to China

Long-term wild bird surveillance across China revealed shifting H5Nx avian influenza patterns, with H5N1, H5N8, and clade 2.3.4.4b viruses changing over time and across migratory flyways. Genomic analyses suggest recent H5Nx detections in China largely reflect repeated reintroductions through migratory birds rather than sustained local circulation.

Taiwan Biobank data reveals ongoing natural selection in living humans

For more than a century, scientists have sought to reconstruct human evolution using diverse lines of evidence, including fossils, genetic variation across populations, and ancient DNA.

NYU Abu Dhabi scientists discover new vulnerability in malaria parasite

Researchers at NYU Abu Dhabi have discovered that the malaria parasite relies on a specific type of fat to survive and multiply within the human host, uncovering a previously unknown vulnerability that could help guide future treatments.

Scientists discover master molecular switch for ginseng saponin production

Sanchi ginseng (Panax notoginseng) is a cornerstone of traditional Chinese medicine, prized for its saponins-bioactive compounds with anti-inflammatory, cardiovascular, and anticancer properties.

Higher neuroticism may curb strenuous exercise, genetic analysis suggests

Researchers used a UK survey and genetic data to examine whether higher neuroticism is associated with lower exercise engagement. Under the study’s Mendelian randomization assumptions, higher neuroticism was estimated to reduce participation in moderate and vigorous physical activity, while conscientiousness may lessen this effect.

Study reveals how DNA misfolding causes congenital heart disease

Congenital heart disease is the most common birth defect, affecting approximately 1 in 100 babies born each year. One of the many causes for this disorder is having only one functional copy of the gene TBX5, instead of two healthy copies, inherited from parents.
