Researchers home in on biological cause of ALS
A mutation linked to amyotrophic lateral sclerosis interferes with the transport of proteins in and out of a cell’s nucleus. Targeting this pathway with drugs or therapies may one day help patients with neurodegenerative disease.
Unique genes in Khoe-San people may lower risk of some pregnancy hazards
An unusual mutation in an immune system gene switches a receptor from one target molecule to another. It’s the first known example of such a change, say Stanford researchers, and likely leads to safer pregnancies.
Brain scans better forecast math learning in kids than do skill tests, study finds
Gray matter volume and connections between several brain regions better forecast 8-year-olds’ acquisition of math skills than their performance on standard math tests.
Scientists say e-cigarettes could have health impacts in developing world
Two researchers are urging greater regulatory oversight of e-cigarettes in poorer countries, where sales of the devices are growing.
Bacterial community in pregnant women linked to preterm birth, study finds
A specific pattern of high bacterial diversity in the vagina during pregnancy increases a woman’s risk of giving birth prematurely, a new study finds.
Researchers design cheaper, faster, more accurate test to identify gene defects in heart patients
A new technique could eventually enable doctors to diagnose genetic heart diseases by rapidly scanning more than 85 genes known to cause cardiac anomalies.
Researchers find mutations that contribute to rare blood cancer
Mutations in immune cells prevented their natural death in roughly half of the cell samples from patients with the incurable cancer, and suggest drug targets for the disease.
Stanford's heart health app launches in Hong Kong and UK
Updates to the MyHeart Counts app include more feedback from other users to help participants improve their own heart health and further contribute to the study.
Elusive liver stem cell identified in mice by researchers
Researchers have found a previously unknown population of cells in mice that function as liver stem cells. The finding could aid drug testing and increase understanding of liver biology and disease.
Dental coverage for patients with Medicaid may not prevent tooth-related ER visits
Access to dental care by low-income Americans has become the exception, rather than the rule, as fewer dentists accept Medicaid, according to a new study.
