Automated detection of sleep states from olfactory brain waves

Researchers create an algorithm that accurately classifies mouse vigilance states into wake, REM sleep, and non-REM sleep based on local brain activity in the olfactory bulb. The study has potential applications in medical and clinical fields, including surgical anesthesia and sleep disorders.

New conservation approach

A new Stanford-led study supports a conservation approach that focuses broadly on ecoregions, providing evidence that these regions meaningfully divide plant and animal communities. This opens a path to more affordable and effective protection of little-known species and valuable natural services.

Preventing sudden cardiac death with genome editing

Researchers at Baylor College of Medicine have successfully used genome editing to correct a genetic mutation causing a rare and deadly heart condition. The study uses CRISPR/Cas9 technology to selectively disrupt the disease-causing gene, reducing arrhythmia symptoms in mice. This breakthrough could lead to a permanent treatment for p...

Restrictive abortion laws in Northern Ireland affect women's health, study shows

Research from the LBJ School of Public Affairs found that Northern Ireland's strict abortion laws have negative consequences for women's physical and mental well-being. Women often face barriers to accessing care, including fear of prosecution, lack of clarity on healthcare provider duties, and challenges in arranging travel or childcare.

Genetic risk factor for erectile dysfunction identified

A new study analyzing the genomes of nearly a quarter of a million men discovered a single-nucleotide polymorphism on Chromosome 6 linked to an increased risk of erectile dysfunction. The genetic locus was consistently associated with ED risk across ethnically diverse groups, suggesting a novel mechanism specific to sexual function.

Nanoparticles to treat snakebites

Researchers developed nanoparticles that bind to venom toxins, mitigating local damage and systemic distribution of toxins in mouse experiments. The treatment has the potential to be administered subcutaneously after a bite, offering a new approach to treating snakebites in rural settings.

Hugs may help protect against conflict-related distress

Receiving hugs on days with interpersonal conflict was associated with smaller decreases in positive emotions and increased negative emotions. The effects of hugs may have lingered, as interviewees reported continued attenuation of negative mood the next day.

Model System Researchers identify factors linked to mortality after traumatic brain injury

Researchers analyzed data from the TBI Model System National Data and Statistical Center to identify physical, cognitive, and psychosocial characteristics associated with mortality in chronic TBI survivors. Independence in mobility and community participation were found to be important factors for long-term survival in this population.

One hundred percent success

The University of Freiburg has been granted two Clusters of Excellence, CIBSS and livMatS, with funding of up to 100 million euros over seven years. The clusters will focus on biological signalling studies and bioinspired materials research.

New gene variants associated with chronic back pain

Researchers have discovered three genetic variants associated with chronic back pain, which may provide clues for understanding its occurrence. The study found that these variants are linked to genes controlling skeletal development and spinal cord function.
