Scientists discovered that SNF5 is a tumor suppressor gene responsible for malignant rhabdoid tumors, a rare and aggressive childhood cancer. The study used a novel knockout technique to create mice with reversible, inverting conditional SNF5 genes, which developed cancers quickly.
A small randomised controlled study of eight patients with ARDS found that re-inflation after suctioning increased lung volume and oxygen levels, suggesting a potential benefit for recovery. The researchers hope this technique could have a positive impact on patient outcomes.
Marcella Kelly uses infrared remotely triggered cameras to photograph jaguars in Belize's Chiquibul Forest Reserve. Her research estimates the presence of at least eight jaguars per 100 square miles, highlighting the species' endangered status due to habitat destruction and illegal hunting.
Scientists have identified a new mammal species in Australia, the short-eared possum, which is morphologically and genetically distinct from the mountain brushtail possum. The discovery highlights the importance of conservation efforts for these two species, which require old-growth forests to survive.
A recent study found that 62.2% of surveyed US adults are classified as incompletely healthy, with most suffering from poor physical health. The researchers identified key factors associated with complete health, including gender, age, marital status, education, and income.
A study estimates that US HIV prevention efforts saved between 204,000 to 1.585 million lives and resulted in cost savings of at least $11 billion since the onset of the epidemic, with a cost per infection prevented ranging from under $50,000 to $6,400.
A study by Dr. David Cumming found significant variation in dilation and curretage (D&C) procedures across Alberta, with some regions experiencing a fivefold increase in rates. Less invasive therapies can accomplish the same goals as D&C, making it an unnecessary procedure for many women, according to the study's findings.
The Darwin Correspondence Project has published 12 of a projected 32-volume set of Charles Darwin's letters, providing a historical view of his ideas on evolution. The project, founded in 1974, is jointly managed by the American Council of Learned Societies and Cambridge University Library.
