BUSM/VA Boston Healthcare System investigators identify new gene linked to PTSD

Scientists have identified a new gene, RORA, linked to post-traumatic stress disorder (PTSD), suggesting that it may play a role in the development of the condition. The study found a significant association between variations in the RORA gene and PTSD, highlighting a potential new avenue for research on how the brain responds to trauma.

COI declarations and off-label drug use

A study by international researchers found that only one in seven authors involved in off-label marketing activities fully disclosed their conflict of interest in published articles. The analysis examined 26 whistleblower complaints and identified 91 doctors and scientists recorded as being involved, with 39 having authored publication...

Wayne State University to search for potential drug targets to treat Barth Syndrome

Researchers at Wayne State University are searching for potential drug targets to treat Barth Syndrome, a rare genetic disorder that affects the heart muscle and energy metabolism. Led by Miriam L. Greenberg, the team hopes to identify new treatments by restoring the TCA cycle metabolites affected by cardiolipin deficiency.

Thinner diabetics face higher death rate

New-onset diabetes in normal-weight adults is associated with significantly higher mortality rates compared to overweight/obese individuals. The study found that older adults and non-white participants are more likely to experience normal-weight diabetes, highlighting the need for targeted health screenings.

Can nature parks save biodiversity?

A recent study published in Nature found that many tropical protected areas are struggling to sustain their biodiversity, despite being our best hope for preserving tropical forests. However, the research also highlights the importance of eliminating threats outside park boundaries and maintaining existing parks.

Planting the seeds of defense

Scientists discovered that exposure to pathogens causes significant changes in a plant's epigenetic code, which helps the plant develop resistance. These epigenetic changes are linked to genes responsible for coordinating stress responses, suggesting the epigenome plays a role in disease resistance.

Study examines racial/ethnic disparities in cranial CT among children

Research suggests racial/ethnic disparities exist in the use of cranial CT scans among children with minor blunt head trauma, particularly for those at lowest or intermediate risk. Children from white non-Hispanic backgrounds may be more likely to undergo the procedure, while those from black or Hispanic backgrounds have lower odds.

Curiosity ready to rove Mars

Curiosity rover successfully landed on Mars in August, beginning its primary mission to assess the planet's surface radiation environment. Researchers will use the Radiation Assessment Detector (RAD) instrument to measure energetic particle species and provide insights into potential habitability.

New research studies policy divergence, voter polarization in elections

A study from University of Illinois economics professors demonstrates a new method to analyze relationships among voters' issue preferences, candidates' policy positions, and voter behavior. The researchers found that policy divergence has increased significantly since the 1970s, particularly on cultural issues.

Anti-angina drug shows protective effects from carbon monoxide

Researchers at the University of Leeds have found that ranolazine can significantly reduce arrhythmias triggered by carbon monoxide exposure. The anti-angina drug works by targeting a sodium channel in the heart, potentially protecting against cardiac events caused by carbon monoxide poisoning.

Birds do better in 'agroforests' than on farms

A University of Utah study found that agroforests with shade-grown coffee and cacao promote greater bird diversity compared to open farmland. The findings suggest that as forests are converted to open agriculture, bird species providing ecosystem services like insect control, seed dispersal, and pollination may decline.

Scientists define new limits of microbial life in undersea volcanoes

A third of Earth's organisms live in rocks and sediments, but their lives have been a mystery. Scientists have now shed light into this dark world by studying methane-exhaling microbes in hot undersea volcanoes. The research reveals that these microbes thrive in environments with low hydrogen levels and have symbiotic relationships bet...

Gladstone scientists discover that epilepsy drug reverses memory loss in animal model of AD

Researchers at Gladstone Institutes found that levetiracetam, an FDA-approved anti-epileptic drug, reverses memory loss and alleviates other Alzheimer's-related impairments in mice genetically modified to simulate key aspects of the disease. The study shows how levetiracetam suppresses abnormal brain activity and restores memory function.
