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.

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.

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.
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.

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.
Engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle. The findings will help lead to a better understanding of how bacteria move from place to place and, potentially, how to keep them from spreading.

Huachansu, a Chinese medicine that comes from the dried venom secreted by the skin glands of toads, has tolerable toxicity levels, even at doses eight times those normally administered, and may slow disease progression in some cancer patients, say US researchers.
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 [...]

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.
