ON HIS first night as a trainee paediatrician in Sylhet, Bangladesh, Mohamad Chisti (pictured above) watched three children die of pneumonia. Oxygen was being delivered to them, through a face mask or via tubes placed ne...

According to researchers, children who carry the APOE4 gene and who are exposed to air pollution have higher behavior problem scores and their attention capacity was slower to develop.

According to a new study, a new metabolic blood test can detect about 17% of children on the autism spectrum

A new peer-reviewed study of weight-loss and sports/energy supplements containing higenamine finds unpredictable and inaccurately labeled dosages of the potentially harmful cardiovascular stimulant.

A natural history study has provided the first comprehensive clinical description of spinal muscular atrophy (SMA) within the Amish and Mennonite communities and correlates ancestral chromosome 5 haplotypes and SMN2 copy...

Researchers report on the development of a new protocol for creating human cortical organoids -- mini-brains derived directly from primary cells that can be used to better explore and understand the real thing.

Researchers have found a mechanism that links epigenetic changes to translational control during fear memory reconsolidation. They report that several particular epigenetic changes in the hippocampus of the rat brain con...

Scientists have developed a better way to identify markers for breast cancer tumors, a breakthrough that could lead to better treatment for millions of women. They used machine learning to rapidly sort images of tumors t...

New research reveals patients with end-stage ankle arthritis can expect enhanced quality of life within six months of surgical reconstruction.

New research suggests that probiotics might not be as effective as we think. Through a series of experiments looking inside the human gut, researchers show that many people's digestive tracts prevent standard probiotics ...

A new approach that distills deluges of genetic data and patient health records has identified a set of telltale patterns that can predict a person's risk for a common, and often fatal, cardiovascular disease, according ...

A tiny change in the very flexible segments of some proteins is enough to trigger rare disorders such as Glut1 deficiency syndrome. A study found that other genetic disorders might be traced back to the same origin.

A study finds that neurogenesis -- inducing the production of new neurons -- in the brain structure in which memories are encoded can improve cognitive function in a mouse model of Alzheimer's disease.

Our immune system can detect when our own cells are damaged. This DNA damage can come from a variety of sources, such as the sun's UV rays, chemical agents like cigarette smoke, or from genotoxic drugs used in chemothera...

Short protein fibers precede the formation of larger deposits that accumulate in the brains of those affected by the incurable Huntington's disease, sometimes called Huntington's chorea, researchers report. These results...

Researchers have developed a novel method for tracking the activity of small molecules in the brain, including the neurotransmitters serotonin and dopamine. Pairing tiny artificial receptors with semiconductor devices th...

Researchers have identified intrinsic cell properties that influence the fate of neural stem cells, affecting what type of brain cell they will form: neurons, astrocytes, or oligodendrocytes. This discovery could give sc...

Currently available vaccines for the prevention of seasonal influenza virus infection have limited ability to induce immunity against diverse H3N2 viruses, an influenza A subtype that has led to high morbidity and mortal...

According to a new study, California's health profile was significantly better than the nation's as a whole -- a profile largely driven by the state's minority population.

Analysis of data captured during a long-term study of aging adults shows that those who report being very sleepy during the day were nearly three times more likely than those who didn't to have brain deposits of beta amy...

Scientists have arrived at a key understanding about how cancers in individual patients spread, or metastasize.

Researchers have identified a system of communication networks that exists among organs and tissues that regulate metabolism. Findings from their study provide, for the first time, a detailed 'atlas' illustrating how the...
