Scientists find a way to boost the body's natural viral defenses

Washington State University researchers have discovered how to "crank up" a natural defense system in the body to combat viral infection, potentially opening a new door for treating virus infections, cancer, neurological disorders and other diseases.

Perceptions of science and scientists shape partisan views on common vaccines

How Americans view science and scientists is strongly associated with whether they think vaccines are safe and effective - and helps explain partisan differences in perceptions of some vaccines, according to a new study led by a team from the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.

New AI model detects hidden diseases in routine CT scans

When analyzed by a new artificial intelligence model developed at Penn Medicine, CT scans reveal much about a patient's health beyond the specific condition they were originally ordered for, according to a new study published in NPJ Digital Medicine.

AI study of 101,000 patients links brown fat to heart and mental health

In a retrospective analysis of PET-CT records from 101,243 patients, researchers found that detectable brown fat was associated with lower prevalence of cardiometabolic and psychiatric conditions, while greater activity, particularly in the axillary region, was linked to more favourable metabolic outcomes. Medication screening identified losartan, which increased brown fat thermogenic activity in laboratory experiments and energy expenditure in mice, although its effects on human brown fat remain unproven.

Highly sensitive people react to social cues over physical environments

Environmental sensitivity may be a misleading name for a personality trait that appears to have less to do with how people respond to their physical environments and more to do with how they are affected by social experiences and perceived threats.

Breast milk antibodies show promise against multiple respiratory viruses

Yona Tugg and colleagues show that a polyclonal secretory immunoglobulin A preparation, purified from breast milk pooled from multiple donors, neutralized respiratory syncytial virus (RSV), human adenovirus type 5, and H1N1 and H3N2 influenza A viruses in laboratory assays.

Does the type of hand sanitizer matter? A study involving 568 people suggests it might

In a 72-day randomized trial involving 568 participants in Japan, an experimental hand sanitizer containing ethanol, benzalkonium chloride, and lactic acid was associated with a 40% lower cumulative incidence of upper respiratory symptoms than a commercial ethanol-based sanitizer. Participants using the experimental formulation also experienced fewer illness-related work restrictions, although infections were not laboratory-confirmed and the proposed residual antimicrobial mechanism was not directly tested.

CSHL researchers find way to make immunotherapy effective against colorectal cancer

Colorectal cancer has become the leading cause of cancer-related death for people under 50. Its most common forms generally aren't treatable, either through conventional means like chemotherapy or newer immunotherapy drugs.
