Hyperactivated brain cells following social trauma impair social reward and promote social avoidance

Past social trauma is encoded by a population of stress/threat-responsive brain cells that become hyperactivated during subsequent interaction with non-threatening social targets. As a consequence, previously rewarding social targets are now perceived as social threats, which promotes generalized social avoidance and impaired social reward processing that can contribute to psychiatric disorders, according to a study […]

Study reveals major problems and gaps in Canada’s process of mandatory HIV screening of migrants

A new landmark study finds that Canada’s process of mandatory HIV screening of migrants is out of step with the OECD and ignores the government’s own policy on medical admissibility to Canada.

INPP5D gene plays key role in enabling microglial cells to prevent plaque buildup

A change in the DNA code (mutation) of a gene that plays a key role in the brain’s immune defenses may prevent related cells from clearing away protein-filled clumps, a new study in mice shows.

Study provides novel therapeutic targets for enhancing the antitumor immunity of γδ-T cells in diabetes

A research team at LKS Faculty of Medicine, The University of Hong Kong (HKUMed) discovered that high glucose impairs the antitumor activity of immune effector γδ-T cells, which contributes to the increased cancer risk in diabetes and that metabolic reprogramming by glucose control may improve the antitumor activity of γδ-T cells.

UW School of Medicine solidifies partnership with Lummi Nation to open more training opportunities

The University of Washington School of Medicine has solidified a partnership with the Lummi Nation to teach medical students and trainees at the Lummi Tribal Health Center in Bellingham, Wash.

Study provides a framework to guide the development of variant-resistant SARS-CoV-2 vaccines

Latest research findings show that vaccine-elicited neutralizing antibodies against SARS-CoV-2 are mostly directed against one of the two main domains of the viral entry machinery.

Computer-based driving program reduces on-road crashes and near crashes among youth with ADHD

A program that combines computer-based and driving simulator training may reduce the proportion of crashes and near crashes among teens with attention-deficit/hyperactivity disorder (ADHD), according to a small study funded by the National Institutes of Health.

Grape consumption protects against ultraviolet UV damage to the skin

A recent human study published this week in the scientific journal Antioxidants found that consuming grapes protected against ultraviolet (UV) damage to the skin. Study subjects showed increased resistance to sunburn after consuming 2 ¼ cups of grapes every day for two weeks.

Elon Musk says Neuralink’s brain-machine interface could enter human studies next year

Elon Musk’s brain-machine interface company Neuralink aims to put its first implant in a human subject in the next six months, he said during an event Wednesday. Musk said the company has been “working hard to be ready for our first human,” and has submitted most of the required paperwork to the Food and Drug […]

Study reveals key details of how DREADD technology highjacks neuronal activity

Understanding of how neuronal activity modulates brain function is a key first step towards creating more effective drugs to treat a variety of neuropsychiatric illnesses, including depression, anxiety, schizophrenia, substance abuse, epilepsy, and others.
