Babies born by caesarean section have different gut bacteria to those born vaginally - but the differences largely disappear after six to nine months

A RUDN University physicist has developed a formula for evaluation of the effect of dark matter on the size of the shadow of a black hole. It turned out that the effect would be noticeable only if the concentration of th...

The pulsar is so massive that it's near the limit of being able to exist at all.

Researchers have investigated how orthopedic surgeons make decisions regarding surgery, and how the decisions are related to how much of their work shift they have completed. The results show that a patient who meets the...

An electronic nose that detects chemicals in the breath of lung cancer patients can identify with 85% accuracy those who will or will not respond to immunotherapy, according to new research.

Combining a new class of drug with two other compounds can significantly shrink lung tumors in mice and human cancer cells, new research shows. The study looked at G12C KRAS inhibitors, a new type of drug that targets a ...

Modifying a class of molecules originally developed to treat the skin disease psoriasis could lead to a new malaria drug that is effective against malaria parasites resistant to currently available drugs.

A molecule once designed to cure the skin disease psoriasis appears to be particularly effective against malaria. The antimalarial properties were revealed thanks to one researcher's inspired hunch when the psoriasis dru...

How does learning to read change our brain? Does reading take up brain space dedicated to seeing objects such as faces, tools or houses? In a functional brain imaging study, a research team compared literate and illitera...

Rubbing hands with ethanol-based sanitizers should provide a formidable defense against infection from flu viruses, which can thrive and spread in saliva and mucus. But new findings challenge that notion -- and suggest t...

Researchers have released a study that shows that a new imaging method 'fast MRI' is effective in identifying traumatic brain injuries in children, and can avoid exposure to ionizing radiation and anesthesia.

A new study has found that using three-dimensional virtual reality models to prepare for kidney tumor surgeries resulted in substantial improvements, including shorter operating times, less blood loss during surgery and ...

A new finding suggests that the pediatric sleep study -- used to diagnose pediatric sleep apnea and to measure improvement after surgery -- may be an unreliable predictor of who will benefit from having an adenotonsillec...

Babies born vaginally have different gut bacteria -- their microbiome -- than those delivered by caesarean, research has shown. Scientists discovered that whereas vaginally born babies got most of their gut bacteria from...

Scientists have discovered a signaling pathway that breast tumors exploit to metastasize to the brain.

Because researchers demonstrated for the first time that a strong association between obesity and chronic diarrhea is not driven by diet or physical activity, the findings could have important implications for how physic...

The immune system is highly complex and a detailed understanding of many underlying mechanisms is still lacking. Only the precise interaction of a variety of factors guarantees a reliable and correct immune response in a...

A team has completed the first study of the effects of a simultaneous infection with blood flukes (schistosomes) and the bacterium Helicobacter pylori -- a fairly common occurrence in some parts of the world. They identi...

Individuals raised in families with higher socioeconomic status were more optimistic in midlife, and in turn, lived longer. Those who experienced more psychosocial stressors, such as parental death, frequent moves and ha...

An international research consortium was able to identify what is likely an optimal combination of chest compression frequency and depth when performing CPR.

A minority of people who use illicit opioids indicated a preference for fentanyl, the super-potent synthetic opioid that accounts for much of the recent rise in US overdose deaths, according to a new study.

A new study finds that most US physician practices and hospitals report screening patients for at least one social need, a trend that is expected to increase in the future, and that practices that care for disadvantaged ...
