(Delft University of Technology) Researchers have succeeded in finding out how bacteria cut themselves into two daughter cells. The bacteria appear to build a new cell wall working from the outside in with the help of mu...

Outdoor air pollution has been linked to 2.7 million preterm births per year, a major study has concluded. When a baby is born preterm (at less than 37 weeks of gestation), there is an increased risk of death or long-ter...

As a last-ditch effort, scientists have announced new radar scans of King Tut's tomb, where they hope to find a potential hidden chamber holding the burial of Queen Nefertiti.

A collaboration between chemists and gene therapy experts produced a new way of inserting the code for modified proteins into the cells of mice. If successful in humans, the technique could be useful for vaccines or canc...

An immune system proteinase called granzyme A appears to promote arthritic inflammation in mice infected with chikungunya virus, scientists report. The study also suggested that granzyme A could serve as a potential targ...

Scientists have discovered that a common type of cell within the human reproductive and intestinal tracts assists HIV in infecting immune cells. Understanding how these cells aid HIV could lead to new methods that preven...

The global proliferation of overweight and obese people and people with type 2 diabetes is often associated with the consumption of saturated fats. Scientists have found that even the one-off consumption of a greater amo...

In a crowded marketplace of products advertised to repel mosquitoes, consumers are wise to trust spray-on repellents containing DEET or PMD, say researchers. In a comparison study of several mosquito-repellent products, ...

A mutation that impacts changes in the shape of an essential viral protein may influence the infectivity of West Nile and other viruses in the flavivirus family, according to a new study.

A study reveals the operation of the biochemical clockwork that drives cellular division in bacteria in extreme detail. It is s an important step forward in research on bacterial growth and could inform efforts to develo...

In mice genetically predisposed to glaucoma, vitamin B3 added to drinking water is effective at preventing the disease. The vitamin administration was surprisingly effective, eliminating the vast majority of age-related ...

Researchers have developed an oncolytic virus capable of redirecting the patient's immune system against their tumor cells. Their work may lead to the development of new therapeutic strategies for several types of cancer...

What dimensions might create the most attractive lips in women? A new study used focus groups and morphed computed images to try to find out because established guidelines may help achieve optimal outcomes in lip augment...

Macrophages, a common type of cell in the vertebrate immune system, can transmit messages between non-immune cells, scientists have discovered. Their paper is the first reported instance of macrophages relaying messages ...

Numerous human diseases, including inflammatory bowel disease, diabetes and autism spectrum disorders are linked to abnormal gut microbiomes, but an open question is whether these altered microbiomes are drivers of disea...

Seawater samples reveal that seagrass areas have much lower levels of a microbe found in sewage - adding to the known benefits of these declining ecosystems

The first evidence of organic material on Ceres opens the door to the possibility that other asteroids harbour precursors to primitive life

CRISPR-Cas9 can be delivered directly into the eye of living animals to treat age-related macular degeneration efficiently and safely, report scientists.

Researchers have successfully "listened in" on the crosstalk between gut microbes and the immune system. This is the first study to perform a system-wide analysis of microbial influence on a broad range of immune cells a...

Scientists have identified a molecule that sends a 'wound-healing' message from tumor cells. If we can disrupt this messaging system, we may be able to fight certain cancers, say scientists.

Emergency patients treated with naproxen and placebo had outcomes as good as or better than patients treated with naproxen and diazepam (trade name Valium) for acute lower back pain, according to the results of a double-...

Genomic testing of biopsies from patients with deadly, treatment-resistant cancerous blood syndromes called histiocytoses allowed doctors to identify genes fueling the ailments and use targeted molecular drugs to success...
