Ten of the world’s most popular pesticides can decimate amphibian populations when mixed together even if the concentration of the individual chemicals are within limits considered safe, according to new research. Such “cocktails of contaminants” are frequently detected in nature, a new article notes.

Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma “jet.”

In a study that could have significant consequences for neural tissue transplantation strategies, researchers report that inactivating a specific gene in adult neural stem cells makes nerve cells emerging from those precursors form connections in the wrong part of the adult brain.

In a new report, researchers have confirmed the accuracy and reliability of SpermCheck Vasectomy, the first FDA approved at-home immunodiagnostic test for detecting low concentrations of sperm.
Images from NASA satellites give a wider perspective of the full extent and devastation of the wildfires raging in Southern California.

A new study found that children who are very distressed when their parents fight have higher levels of the stress hormone cortisol. Distress, hostility, and level of involvement parental arguments were measured in 208 six-year olds. Cortisol levels were measured by taking saliva samples before and after simulated telephone arguments between their parents. Children who [...]

As much as a third of Mars could have been underwater, scientists say. An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA’s Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient Mars.

Even seasoned doctors have a difficult time diagnosing pneumonia in hospitalized patients breathing with the assistance of a ventilator. That’s because a patient’s underlying illness often skews laboratory test results and masks pneumonia’s symptoms. Now, researchers report they have validated the use of gene chip technology to rapidly and accurately detect pneumonia associated with ventilator [...]

Cholesterol crystals released in the bloodstream during a cardiac attack or stroke can damage artery linings much further away from the site of the attack, leaving survivors at greater risk than previously thought.
