Researchers identify molecules that rein in CRISPR systems

Scientists have identified the first chemical compounds able to inhibit and regulate CRISPR systems, which could ultimately make CRISPR gene-editing technologies more precise, efficient, and safe. To identify these compounds, the researchers developed a new platform for rapidly finding small molecules that suppress CRISPR enzymes. Sometimes referred to as “anti-CRISPRs,” […]

Dangerous Pathogens Use This Sophisticated Machinery to Infect Hosts

Gastric cancer, Q fever, Legionnaires' disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to […]

Cellular rivalry promotes healthy skin development

Not all cells are destined for greatness. Deemed unfit to serve in the body, some are killed off during early development through a process called cell competition. This phenomenon has previously been documented in flies and is now turning out to occur in mammals as well. In a recent study, […]

Alzheimer's disease discovery: A human-specific gene protects neurons against amyloid beta protein

University at Buffalo researchers have identified the first human-specific fusion gene—a hybrid of two genes—implicated in Alzheimer’s disease. The finding suggests that a neurotransmitter receptor, previously successful in animal studies but that failed in human trials for Alzheimer’s, might still turn out to be a valuable therapy. In a paper published in […]

Artificial Intelligence Could Vastly Scale Up Alzheimer’s Research

Machine Learning Tool Automates Pathologists’ Work to Identify Disease Markers. Researchers at UC Davis and UC San Francisco have found a way to teach a computer to precisely detect one of the hallmarks of Alzheimer’s disease in human brain tissue, delivering a proof of concept for a machine-learning approach capable […]

Yale study identifies how cancer drug inhibits DNA repair in cancer cells

According to researchers at Yale Cancer Center, a cancer drug thought to be of limited use possesses a superpower of sorts: It is able to stop certain cancer cells from repairing their DNA in order to survive. The study, published in the journal Science Translational Medicine, suggests that combining this drug, cediranib, […]

Injections, exercise promote muscle regrowth after atrophy in mice, study finds

By injecting cells that support blood vessel growth into muscles depleted by inactivity, researchers say they are able to help restore muscle mass lost as a result of immobility. The research, conducted in adult mice, involved injections of cells called pericytes (PERRY-sites), which are known to promote blood vessel growth […]
