Adding back a tiny molecule, microRNA 223-3p, to BRCA1-mutant cancer cells forces the cancer to die, researchers discovered. BRCA1-mutant cancer is the type of inherited cancer for which Angelina Jolie had preventive sur...

Natural Killer (NK) cells have long been the soldiers of the immune system that prevents the growth and spread of cancers, and subduing this army of cells is one of the key ways that tumours take hold. Researchers have d...

Prenatal exposure to the organophosphate pesticides has been linked to poorer cognition and behavior problems in children. A new study is one of the first to use advanced brain imaging to reveal how exposure can actually...

Schwann cells form a protective sheath around nerve fibers and ensure that nerve impulses are transmitted rapidly. If these cells are missing or damaged, severe neurological diseases may occur as a result. Researchers ha...

Think of a memory from your childhood. Are you seeing the memory through your own eyes, or can you see yourself, while viewing that child as if you were an observer?

A specific gene associated with autism appears to undergo changes in the sperm of men who use marijuana, according to new research. The gene change occurs through a process called DNA methylation, and it could potentiall...

Bio-compatible gold nanoparticles designed to convert near-infrared light to heat have been shown to safely and effectively ablate low- to intermediate-grade tumors within the prostate, according to a new study.

A team has developed a breathalyzer device that can measure the amount of tetrahydrocannabinol (THC), the psychoactive compound in marijuana, in the user's breath. The breathalyzer was developed using carbon nanotubes, t...

Scientists are using nanoparticle screening on personal care products and finding previously thought toxic chemicals may not be harmful. Researchers discuss their work successfully using microchips to demonstrate titaniu...

Children who grow up in disadvantaged neighborhoods are nearly one-third more likely to experience obesity as adults, according to new research.

Scientists have found a vulnerability in cancer cells that could make them more susceptible to being destroyed by the immune system, according to a new report.

The largest clinical study of its kind to look at the effects of strict alternate-day fasting in healthy people has shown a number of health benefits. The participants alternated 36 hours of zero-calorie intake with 12 h...

Elevated left ventricular mass, known as left-ventricular hypertrophy, is a stronger predictor of coronary artery disease-related death and heart failure than coronary artery calcium score, according to a new study.

Patients with non-small cell lung cancer (NSCLC) now have more improved treatment options compared to standard of care with the addition of several new agents called immune-checkpoint inhibitors (ICI). Despite these chan...

A team led by the scientist has now discovered how inactivation of a certain lipid kinase promotes mTor complex 1 activity, and may therefore constitute a new point of attack for the treatment of diabetes and cancer.

New study reveals enzyme plays key role in potentially fatal dengue haemorrhagic fever and shock; suggests clinically approved tryptase inhibitor could be key in future targeted treatment.

Our body makes antibodies to fight infections. But the synthetic versions of these molecules could hold the key to stimulating the body's ability to regenerate.

Researchers applying artificial intelligence to electrocardiogram data estimated the age group of a patient and predicted their gender. Artificial intelligence could more accurately track overall health status by determi...
