WRAIR scientists demonstrated that TBI biomarkers were elevated among law enforcement and military personnel, including those without a diagnosed brain injury or concussion, repeatedly exposed to low level blast. Repeated exposure have been linked to a series of reported symptoms such as headaches, fatigue, dizziness, memory difficulties, and tinnitus. Researchers hope these data are the first step to identifying objective biomarkers as clinically relevant diagnostic tools.

Pyrosomes spend their entire lives in the open ocean and therefore easily go unnoticed. Nevertheless, they are key components of deep-sea ecosystems. This is shown by a novel study conducted off the Cabo Verde Islands led by an international team under the leadership of GEOMAR Helmholtz Centre for Ocean Research Kiel.

Swansea University scientists have uncovered potentially dangerous chemical pollutants that are released from disposable face masks when submerged in water. The research reveals high levels of pollutants, including lead, antimony, and copper, within the silicon-based and plastic fibres of common disposable face masks.

A team of international researchers, including Dr Rich Crane from the Camborne School of Mines, University of Exeter, have developed a new method to extract metals, such as copper, from their parent ore body.

New, high-resolution VLA images of a giant molecular cloud where new stars are being born show changes since a set of observations made more than two decades ago. Tracking changes in this region over time can reveal new details about the process of star formation and the interactions of outflows from young stars.

A new auroral phenomenon discovered by Finnish researchers a year ago is probably caused by areas of increased oxygen atom density occurring in an atmospheric wave channel. The speculative explanation offered by the researchers gained support from a new study.

By using silicone polymers, the scientists have made the softest brain implant to date with the thickness of a thin sewing thread (~0.2 mm), and the consistency of soft pudding - as soft as the brain itself. They were then able to implant it into the brain using a trick from the cookbook.

If you come from a family where people routinely live well into old age, you will likely have better cognitive function (the ability to clearly think, learn and remember) than peers from families where people die younger. Researchers affiliated with the Long Life Family Study (LLFS) recently broadened that finding in a paper published in Gerontology, suggesting that people who belong to long-lived families also show slower cognitive decline over time.

A new paper from the University of Georgia suggests that unconscious biases in the health care system may have influenced how individuals with intellectual disabilities were categorized in emergency triage protocols.

University of Bristol research into octopus vision has led to a quick and easy test that helps optometrists identify people who are at greater risk of macular degeneration, the leading cause of incurable sight loss.

T-cell acute lymphoblastic leukemia is an aggressive cancer type that mostly affects children. The standard treatment is chemotherapy, but about one in four patients do not respond or develop resistance to this. Now, researchers from the University of Copenhagen have found a combination treatment that could benefit these patients and increase the survival rate.

The majority of top-rated fertility apps collect and even share intimate data without the users' knowledge or permission, a collaborative study by Newcastle University and Umea University has found. Researchers are now calling for a tightening of the categorisation of these apps by platforms to protect women from intimate and deeply personal information being exploited and sold.

Researchers are listening in on honeybee hives, hoping to decipher their complex communication patterns and what they might signal about broader ecosystem health. A novel method for monitoring colony health through changes in its electrostatic field is released in a recent paper by the open access publisher Frontiers.

It might be a good idea to look for inspiration in nature when designing load-bearing foundations for buildings. Researchers from Aarhus University and University of California Davis have delved into pile foundations and found, that piles with snake inspired surface patterns give 25-50 per cent less resistance during installation compared with the pressure they can subsequently support. The findings have been published in Acta Geotechnica.

Cancerous tumors thrive on blood, extending their roots deep into the fabric of the tissue of their host. They alter the genetics of surrounding cells and evolve to avoid the protective attacks of immune cells. Now, Penn State researchers have developed a way to study the relationship between solid, difficult-to-treat tumors and the microenvironment they create to support their growth.

Measures to contain the Corona pandemic are the subject of politically charged debate and tend to polarize segments of the population. Those who support the measures motivate their acquaintances to follow the rules, while those who oppose them call for resistance in social media. But how exactly do politicization and social mobilization affect the infection figures? Researchers at the Max Planck Institute for Human Development have examined this question using the USA as an example.

A new Boston University School of Public Health (BUSPH) study has identified for the first time how the aryl hydrocarbon receptor (AhR), an environmental chemical receptor, drives immunosuppression in oral squamous cell carcinoma (OSCC)--and that its removal from malignant cells can result in tumor rejection.

Mixed-cation single crystals narrow the gap between perovskite and top-performing semiconductor solar cells.

Tokyo University of Agriculture and Technology (TUAT) researchers studied the nonlinear dynamics responsible for "power hop" instabilities in tractors. They found that bouncing, friction, and joint free-play are all critical factors for modeling this outcome. Understanding how this dynamic instability occurs can help improve industrial safety.

Sea turtles in the Cayman Islands are recovering from the brink of local extinction, new research shows.
