The role of the e-bike in promoting health and fitness is comparable to that of a conventional bicycle. This was reported by researchers of the University of Basel in the Clinical Journal of Sport Medicine. In particular, overweight and untrained individuals can benefit from riding an e-bike.

Scientists at Scripps Research have uncovered a new strategy to kill tumors, including some triple-negative breast cancers, without harming healthy cells, a discovery that could lead to more ways to treat tumors while reducing side effects.

Rice University scientists have released the first results of extensive water sampling in Houston after the epic flooding caused by Hurricane Harvey. They found widespread contamination by E. coli, likely the result of overflow from flooded wastewater treatment plants.

New-generation lung cancer drugs have been effective in a large number of patients, but within about a year, the patients tend to develop resistance to the therapy. Researchers at the Weizmann Institute of Science, in collaboration with physicians, have conducted a study in mice, in which they used existing drugs in a new combination to help crush potential resistance to the treatment. Their findings were published recently in the journal Clinical Cancer Research.

Many city drinking water systems add softening agents to keep plumbing free of pipe-clogging mineral buildup. According to new research, these additives may amplify the risk of pathogen release into drinking water by weakening the grip that bacteria – like those responsible for Legionnaires’ disease – have on pipe interiors.

Researchers at MIT have created what may be the smallest robots yet that can sense their environment, store data, and even carry out computational tasks. These devices, which are about the size of a human egg cell, consist of tiny electronic circuits made of two-dimensional materials, piggybacking on minuscule particles called colloids.

Suicide rates are likely to rise as the earth warms, according to new research published July 23 in Nature Climate Change. The study, led by Stanford economist Marshall Burke, finds that projected temperature increases through 2050 could lead to an additional 21,000 suicides in the United States and Mexico.

Greening vacant urban land significantly reduces feelings of depression and improves overall mental health for the surrounding residents, researchers from the Perelman School of Medicine and the School of Arts & Sciences at the University of Pennsylvania and other institutions show in a new randomized, controlled study published in JAMA Network Open. The findings have implications for cities across the United States, where 15 percent of land is deemed “vacant” and often blighted or filled with trash and overgrown vegetation.

In a perspective published in the July 20 issue of Science, Neal Stewart and his University of Tennessee coauthors explore the future of houseplants as aesthetically pleasing and functional sirens of home health.

Ultrasound waves applied to the whole brain improve cognitive dysfunction in mice with conditions simulating vascular dementia and Alzheimer's disease. The research, conducted by scientists at Tohoku University in Japan, suggests that this type of therapy may also benefit humans.
