UT Southwestern scientists closing in on map of the mammalian immune system

Researchers used a machine-learning algorithm to identify novel gene candidates associated with immune traits in mice, including 101 new genes with over 95% chance of being required for immunity. The study's software, Candidate Explorer, helps predict causation of mutations and has already verified hundreds of genes with novel functions.

Setting COVID-19 drug trials up for success

A new modeling study suggests that randomization and early recruitment in COVID-19 clinical trials can help identify effective antiviral drugs. The researchers found that timing of treatment initiation also plays a crucial role, with treatments administered within the first day of symptom onset showing improved outcomes.

New risk model may improve the prediction of preterm birth

A new risk prediction model may improve the prediction of impending spontaneous preterm birth, reducing unnecessary hospital admissions and treatment costs. The model combines clinical risk factors with vaginal fluid fetal fibronectin concentration analysis, showing promising performance in predicting preterm birth within seven days.

Developing new techniques to build biomaterials

Scientists at the University of Leeds have developed an approach to control the structure and mechanics of synthetic biomaterials made from proteins. By removing specific chemical bonds, known as 'protein staples,' they altered the structure of a protein network, resulting in different mechanical properties.

Satellite galaxies can carry on forming stars when they pass close to their parent galaxies

Using numerical simulations, researchers showed that satellite galaxies can retain gas and experience new episodes of star formation after passing close to their parent galaxy. This process is driven by the satellite's reserve of cold gas and minimum distance from its parent galaxy.

Safe nurse staffing standards in hospitals saves lives and lowers costs

A new study found that establishing safe nurse staffing standards in hospitals in Chile could significantly improve patient outcomes and reduce healthcare costs. The research revealed that private hospitals had better nurse-to-patient ratios than public hospitals, resulting in lower avoidable deaths and hospital readmissions.

Bacterial survival kit to endure in soil

Acidobacteria use low-affinity terminal oxidases to 'breathe' oxygen at nanomolar concentrations, challenging traditional assumptions. These microbes also scavenge atmospheric hydrogen to survive nutrient-poor periods, playing a central role in soil microbial communities and ecological balance.

Engineered cells successfully treat cardiovascular and pulmonary disease

Scientists at UCSF have shown that gene-edited cellular therapeutics can effectively treat major diseases such as peripheral artery disease, chronic obstructive pulmonary disease, and heart failure. The study used specially engineered induced pluripotent stem cells called HIP cells to evade the immune system.

Keeping bacteria under lock and key

Scientists at the University of Delaware have made progress on a biological containment strategy using synthetic auxotrophy, keeping a strain of E. coli stable for 100 days. The research also shows promise for treating diseases and cleaning up the environment safely.

"All the lonely people": The impact of loneliness in old age on life and health expectancy

A study by Duke-NUS Medical School finds that lonely older adults can expect to live a shorter life than their peers, forfeiting potential years of good health. In Singapore, where collectivistic culture and rapidly ageing population make loneliness more detrimental, loneliness among seniors has become a social and public health concern.

High risk of divorce after TBI? Not necessarily, study suggests

A recent study published in the Journal of Head Trauma Rehabilitation found that two-thirds of patients with traumatic brain injury (TBI) remain married to their spouse 10 years after the injury. The study analyzed data from 1,423 patients and found that marital stability was higher for those who were older, female, and had no problema...

From eyebrow beans to 'lost' rice: community seedbanks are protecting China's crops

China's community seedbanks are conserving agricultural biodiversity by protecting crop varieties, improving farmer livelihoods, and increasing food security. These seedbanks also promote climate resilience through their focus on local environmental conditions.

Sexual reproduction without mating

Scientists identify edible wild mushroom with complex reproductive structure, challenging traditional understanding of fungal reproduction. The study reveals a new type of reproduction that recombines genetic information without a mate, potentially increasing ecological fitness and adapting to previously unsuitable habitats.

Muscles retain positional memory from fetal life

Researchers at Kumamoto University discovered that muscles and satellite cells retain positional memory from fetal life, based on the expression pattern of the homeobox (Hox) gene cluster. This finding is expected to provide insights into the pathogenesis of muscle diseases and develop regenerative medicine.

Context in science reporting affects beliefs about, and support for, science

A new study led by a University at Buffalo researcher shows that the way news media talk about science focuses too much attention on individuals, leading to inaccurate perceptions of scientific accuracy and reliability. The study suggests that contextualizing failure stories within the scientific process can help ameliorate harm to sci...
