Popular painkillers can be used as personal dosimeters in a radiation emergency

When proper precautions are taken, radioactive substances are extremely safe to use. But what if they leak into the environment in an uncontrolled manner? Then it becomes crucial to find out the dose of radiation people may have absorbed.

Optical nanoscopy reveals how SARS-CoV-2 infection alters human airway cells

How do viruses reorganize host cells with spatial and molecular specificity? Researchers from the Netherlands provided new insights in a recent study posted to the bioRxiv* preprint server, where they use optical nanoscopy to look at severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-triggered changes in primary human airway cells.

Metabolism peaks much earlier and starts to decline later than you might think

Most of us remember a time when we could eat anything we wanted and not gain weight. But a new study suggests your metabolism, the rate at which you burn calories, actually peaks much earlier and starts its inevitable decline later than you might think.

Immunotherapy pairs ultrasound with immune cells to destroy tumors without toxic side effects

Bioengineers at the University of California San Diego have developed a cancer immunotherapy that pairs ultrasound with cancer-killing immune cells to destroy malignant tumors while sparing normal tissue.

Novel blood test as adjunct to MRI improves prostate cancer screening

Researchers at Karolinska Institutet in Sweden recently reported that magnetic resonance imaging (MRI) could reduce overdiagnoses and thereby improve prostate cancer screening.

Weighted restraint linked to increased breathing effort after physical exercise

Weighted restraint, which is used in law enforcement when officers apply their body weight to a subject to control their movements during apprehension, is associated with increased breathing effort after physical exercise, according to a study published in Scientific Reports.

New research offers hope to increase efficacy of immunotherapy for lung cancer

Lung cancer is the leading cause of cancer-related death. Current treatments employ immunotherapy, often in combination with chemotherapy, but benefits to patients remain slight.

Ten-fold reduced risk of workplace SARS-CoV-2 infection in seropositive essential workers

A reassuring new study supports the opening of workplaces to seropositive workers in view of the extremely low risk of reinfection observed in this cohort.

Two-arm molecule can deplete cancer-protecting cells to promote immune responses against tumors

A two-arm molecule can effectively deplete cancer-protecting cells inside tumors, allowing the immune system to fight off tumors without becoming overactive. The finding, published online in Science Translational Medicine, could lead to new types of cancer immunotherapies.

Risk factors for hospitalization among HIV patients infected with SARS-CoV-2

The hospitalization of PWH with COVID-19 is related to host factors such as older age and co-morbidities, rather than due to traditional metrics of HIV.

Understanding hypoxia-induced gene expression variations in aggressive type of pancreatic cancer

Cancer cells have evolved a myriad of mechanisms that support their uncontrolled growth. In case of solid tissue tumors, the tumor microenvironment, which consists of extracellular components and conditions surrounding the tumor, is crucial in deciding the fate of the cancer cells.

Researchers aim to identify gene-lifestyle interactions that contribute to cardiometabolic disease risk

Researchers at Washington University School of Medicine in St. Louis have received a four-year, $8.8 million grant to ramp up research aimed at unraveling how an individual's risks of cardiometabolic diseases, such as heart disease and Type 2 diabetes, are influenced by the interaction of specific genes with demographic and lifestyle factors.
