Since the introduction of statins to treat high cholesterol, the decline in lipid levels experienced by the wealthy has been double that experienced by the poor. Statin use may have contributed to expanding social disparities in the treatment of cardiovascular disease, according to new research.

Scientists have discovered molecules that could confuse insects' ability to detect plants by interfering with their sense of smell. This could reduce damage to crops by insect pests and contribute to food security.

Late-breaking results from the PROSPECT clinical trial shed new light on the types of vulnerable plaque that are most likely to cause sudden, unexpected adverse cardiac events, and on the ability to identify them through imaging techniques before they occur.

A dark red area discovered on the dwarf planet Haumea appears to be richer in minerals and organic compounds than the surrounding icy surface.

Insulin resistance, the hallmark of type 2 diabetes and a condition often associated with obesity, is paradoxically also an apparent contributor to muscle wasting and severe fat loss that accompanies some cancers, according to new research.

Scientists recently completed a study showing the link between personality, survival and reproductive success in male bighorn sheep. In addition to being a significant advance in our knowledge of these mammals, the research offers insight into personality differences in animals and humans, from an evolutionary perspective.

A majority of medical schools surveyed report they have experienced incidents of students posting unprofessional content online, including incidents involving violation of patient confidentiality, with few schools having policies to address these types of postings, according to a new study.

A new study demonstrates that the same proteins produced by humans early during infection are also made by fish early after exposure to harmful germs. These proteins activate the fish immune system in a process that resembles that in humans. But unlike humans, the inflammatory response in young zebrafish is simple, making it easier to tease out the pathways involved in the fight against infection.

Researchers have shown for the first time that patterns of ultrasound signals can be used to identify whether or not cancer has started to spread in melanoma patients, and to what extent. The discovery enables doctors to decide on how much surgery, if any, is required and to predict the patient's probable survival.

Using state-of-the-art electron microscopy techniques, researchers have for the first time visualized and described the precise arrangement of chemoreceptors -- the receptors that sense and respond to chemical stimuli -- in bacteria. In addition, they have found that this specific architecture is the same throughout a wide variety of bacterial species, which means that this is a stable, universal structure that has been conserved over evolutionary time.
