Rocks on Mars may provide link to evidence of living organisms roughly 4 billion years ago
|
A new paper reveals groundbreaking research on the hydrothermal formation of Clay-Carbonate rocks in the Nili Fossae region of Mars. The findings may provide a link to evidence of living organisms on Mars, roughly 4 billion years ago in the Noachian period.

Audubon's first engraving of a bird discovered
|
In 1824, John James Audubon (1785-1851), the eminent American artist, created a drawing of a running grouse for use in the design for a New Jersey bank note. Although the artist mentions the drawing and the resulting engraved paper money in two separate diary entries, no one has ever been able to locate or identify such an illustration. Until now.

Resting brain activity associated with spontaneous fibromyalgia pain
|
A recent study provides the first direct evidence of linkage between elevated intrinsic (resting-state) brain connectivity and spontaneous pain intensity in patients with fibromyalgia. This research shows an interaction of multiple brain networks, offering greater understanding of how pain arises.

Most youth hockey injuries caused by accidents, not checking, study shows
|
Hockey fans likely would assume that body-checking -- intentionally slamming an opponent against the boards -- causes the most injuries in youth ice hockey. But they would be wrong.

Cell-of-origin for human prostate cancer identified for first time
|
Scientists have identified for the first time a cell-of-origin for human prostate cancer, a discovery that could result in better predictive and diagnostics tools and the development of new and more effective targeted treatments for the disease.

Fluorescent biosensor to aid in drug development
|
Scientists have developed a new fluorescent biosensor that could aid in the development of an important class of drugs that target a crucial class of proteins called G protein-coupled receptors (GPCRs). GPCRs are popular drug targets because of the pivotal role they play in cells' communication circuits responsible for regulating functions critical to health, including circuits involved in heart and lung function, mood, cognition and memory, digestion and the inflammatory response.

Vascular-targeted photodynamic therapy for localized prostate cancer
|
NYU Langone Medical Center has begun a clinical trial offering vascular-targeted photodynamic therapy to patients with localized prostate cancer. This novel, minimally invasive procedure uses a light-activated drug to deliver light energy waves by way of laser fibers in order to destroy prostate cancer cells.

Psychologists develop two potent new predictors of suicide risk
|
Two powerful new tests developed by psychologists show great promise in predicting patients' risk of attempting suicide. The work may help clinicians overcome their reliance on self-reporting by at-risk individuals, information that often proves misleading when suicidal patients wish to hide their intentions.

Some trees 'farm' bacteria to help supply nutrients
|
Some trees growing in nutrient-poor forest soil may get what they need by cultivating specific root microbes to create compounds they require. These microbes are exceptionally efficient at turning inorganic minerals into nutrients that the trees can use.

Best hope for saving Arctic sea ice is cutting soot emissions, say researchers
|
Soot from the burning of fossil fuels and solid biofuels contributes far more to global warming than has been thought, according to a new study. But, unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Controlling it may be the only option for saving the Arctic sea ice before it all melts.
