Some fish will leap out of water to escape a predator, but Northern Arizona University researcher Alice Gibb has observed that the mosquitofish chooses the most energy-efficient method for returning—a finding that has evolutionary implications.

The research shows that for better heart health, rich countries should continue to deliver high quality health care while trying to reduce risk factors, while poor countries need to avoid the rise of risk factors but also substantially improve their health care.

Oxidized lipids are known to play a key role in inflaming blood vessels and hardening arteries, which causes diseases like atherosclerosis. A new study at UCLA demonstrates that they may also contribute to pulmonary hypertension, a serious lung disease that narrows the small blood vessels in the lungs. Using a rodent model, the researchers showed that a peptide mimicking part of the main protein in high-density lipoprotein (HDL), the so-called “good” cholesterol, may help reduce the production of oxidized lipids in pulmonary hypertension. They also found that reducing the amount of oxidized lipids improved the rodents’ heart and lung function.

A New Report Examines First Reported Spread of Vaccinia Virus Through Shaving After Contact Transmission
A 30-year-old unvaccinated male security forces student is the first reported case of spreading the smallpox vaccine virus (vaccinia) across his face by shaving after he had inadvertently acquired the virus during combative training at the largest U.S. Air Force training installation, according to a recently released health surveillance report.

The mechanical force that a single fungal cell or bacterial colony exerts on a plant cell may seem vanishingly small, but it plays a heavy role in setting up some of the most fundamental symbiotic relationships in biology, according to a new study led by Jean-Michel Ané, a professor of agronomy at the University of Wisconsin-Madison.
