Scientists have devised a new type of superconducting circuit that behaves quantum mechanically — but has up to five levels of energy instead of the usual two. These circuits act like artificial atoms in that they can only gain or lose energy in packets, or quanta, by jumping between discrete energy levels.

Scientists know that small, grape-like clusters of a protein called the amyloid beta-protein are toxic, causing Alzheimer’s (AD). By creating various sizes of clusters in the lab that exactly match what forms in AD brains, neurologists have determined the toxicity of these clusters, and suggest a target for future drugs.

Long known for its antioxidants, immune boosting and, most recently, antihypertensive properties, black tea could have another health benefit. Black tea may be used to control diabetes, according to a new study.
A new study of persistent asthma in inner-city adolescents and young adults finds that an extensive set of clinical tests cannot successfully predict the future risk of asthma attacks in participants who both receive care based on current guidelines and adhere to treatment recommendations.

Researchers have for the first time shown that nanotubes can grow without a metal catalyst. The researchers demonstrate that zirconium oxide, the same compound found in cubic zirconia “fake diamonds,” can also grow nanotubes, but without the unwanted side effects of metal.

Mothers and fathers play different roles and make different contributions to a child’s upbringing, but a father’s influence upon a child’s academic success later in life is felt the most when he’s involved from the very beginning, according to a new study.

Scientists describe new details about a fungal parasite that coerces ants into dying in just the right spot — one that is ideal for the fungus to grow and reproduce. Their study shows just how precisely the fungus manipulates the behavior of its hapless hosts.

Elderly individuals who had a diet that included higher consumption of fruits, vegetables, legumes, cereal and fish, and was low in red meat and poultry and who were physically active had an associated lower risk of Alzheimer disease, according to a new study. In a separate study, higher adherence to a Mediterranean diet was associated [...]
In 2002, leopards in were legally — but unsustainably — hunted by trophy hunters, and illegally hunted by farmers because of the threat they pose to livestock. In order to reduce leopard killings, scientists have worked with local policy makers to create sustainable conservation solutions. In 2006, recommendations were successfully implemented and by 2008 data [...]
A new development may provide powerful new test for inflammatory lung diseases. Chronic inflammatory lung diseases like chronic bronchitis and emphysema are a major global health problem, and the fourth leading cause of death and disability in developed countries, with smoking accounting for 90% of the risk for developing them. New work has shed light [...]
