Diseased trees new source of climate gas

Researchers at Yale University have discovered that diseased trees in forests can produce massive amounts of methane, a potent greenhouse gas. The estimated emission rate from an upland site is equivalent to burning 40 gallons of gasoline per hectare of forest per year.

Increasing federal match funds for states boosts enrollment of kids in health-care programs

New research from the University of Michigan found that a 10-percentage-point increase in federal matching funds for Medicaid and CHIP is associated with an increase of 1.9 percent in the number of children enrolled in Medicaid nationwide. This translates to approximately 500,000 additional children gaining health insurance coverage.

Searching for tumors or handguns can be like looking for food

A laboratory study conducted by Duke University psychologists found that the brains of humans, including radiologists and baggage screeners, evolved to solve foraging problems in similar ways. The researchers discovered that people with fewer targets to find gave up on a given screen sooner compared to those with more targets.

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.
