Scientists have built a device from metamaterials and transformational optics that delivers a complex set of instructions capable of guiding light with unprecedented accuracy. The discovery expands on earlier “cloaking” efforts to guide light around objects or space.

Biologists are offering a new theory for the long-standing mystery of why male lemurs are no larger than females. The theory posits that male lemurs guard their mates just like other primates. But whereas evolution favors larger males in gorillas and other species that guard females by fighting, lemurs have evolved to passively guard their [...]
Patients with cystic fibrosis usually experience significant muscle loss, a symptom traditionally considered to be a secondary complication of the devastating genetic disease. However, a recent study reverses the equation: new results show that muscle atrophy and weakness may be a primary symptom caused by the effects of CFTR gene mutations on the muscle itself.

One of the most well-known psychological tools is the Rorschach Inkblot Test. A viewer looks at ten inkblots, one at a time, and describes what they see. However, does the inkblot really reveal all? According to a new article, the Rorschach may not be the best diagnostic tool and practitioners need to be cautious in [...]

A virus discovered in a rare form of skin cancer has been found in people with squamous cell carcinoma, a common skin cancer. Researchers identified the virus in more than a third of 58 SCC patients and in 15 percent of their tumors. Virus found in tumor cells had a mutation that could enable it [...]

Scientists have identified a substance in the liver that helps process fat and glucose. That substance is a component of the common food additive lecithin, and researchers speculate it may one day be possible to use lecithin products to control blood lipids and reduce risk for diabetes, hypertension or cardiovascular disease using treatments delivered in [...]

Inhibiting an enzyme in the brains of newborns suffering from oxygen and blood flow deprivation stops brain damage that is a leading cause of cerebral palsy, mental retardation and death, according to researchers. The scientists show blocking the brain enzyme, tissue-type plasminogen activator, in newborn rats prevented progressive brain damage triggered by the lack of [...]
