Stanford researchers have reclaimed bragging rights for creating the world’s smallest writing, a distinction the university first gained in 1985 and lost in 1990. How small is the writing? The letters in the words are assembled from subatomic sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter.

Two common strains of methicillin-resistant Staphylococcus aureus, commonly known as MRSA, were virtually eradicated in the laboratory by exposing them to a wavelength of blue light, in a process called photo-irradiation.

Scientists have selected 262 European observatories which analyzed the series of minimum and maximum daily temperatures from 1955 to 1998 to estimate trend variations in extreme temperature events. According to the study, in Europe days of extreme cold are decreasing and days of extreme heat increasing. From 0.5ºC to 1ºC in the average minimum temperature, [...]

Researchers in Texas are reporting that quantum dots (QDs) — a product of the revolution in nanotechnology increasingly used in electronics, solar cells, and medical imaging devices — may be toxic to cells under acidic or alkaline conditions. Their study is the first to report on how different pH levels may affect the safety of [...]

Followers are just as important to good leadership as are the leaders themselves, reveals a new study of stickleback fish. By randomly pairing fish of varying degrees of “boldness,” the researchers showed that each member of a pair adopts the role of leader or follower. More importantly, they found, the behavior of each member of [...]

Researchers have widely believed that the organic compound, allicin — which gives the pungent vegetable its aroma and flavor — acts as an antioxidant. But until now it hasn’t been clear how allicin works, or how it stacks up compared to more common antioxidants such as Vitamin E and coenzyme Q10, which stop the damaging [...]

Mice whose fat cells were allowed to grow larger than fat cells in normal mice developed “healthy” obesity when fed a high-fat diet, researchers found in a new study.

What causes motor complications of Parkinson’s treatment? Researchers have now identified two molecules whose expression in the brain is altered in the brains of animals with side effects related to Parkinson’s disease. The results may lead to new approaches to the treatment of these side effects in Parkinson’s patients.

Transplant surgeons have evidence that hospitals performing at least 20 lung transplant procedures a year, on average, have the best overall patient survival rates and lowest number of deaths from the complex surgery.
