Researchers from EPFL have shown that the surface of minuscule water drops with a 100 nm size is surprisingly ordered. At room temperature, the surface water molecules of these droplets have much stronger interactions than a normal water surface. The structural difference corresponds to a difference in temperature of -50°C, which may shed new light on a variety of atmospheric, biological and even geological processes.
Viruses are thought to frequently kill their host bacteria, especially at high microbial density. A state called lysogeny, in which viruses lie dormant but don't kill their hosts, has been thought to be relatively rare , mostly occurring at low bacterial concentrations. A new study suggests lysogeny might be much more common than previously believed. These findings could lead to a better understanding of degraded coral reef ecosystems and how to preserve them.
Falling sulfur dioxide emissions in the United States are expected to substantially increase rainfall in Africa's semi-arid Sahel, while bringing slightly more rain to much of the US, according to a new study in the Journal of Geophysical Research: Atmospheres.
Researchers have found that carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the sun -- sometimes cooling the air and at other times warming it.
A new study has found that children, especially boys, whose mothers were exposed to higher levels of outdoor particulate air pollution at the same time that they were very stressed were most likely to develop asthma by age six. The study was presented at the 2017 American Thoracic Society International Conference.
High levels of air pollution over time may get in the way of a good night's sleep, according to new research presented at the ATS 2017 International Conference.
Algal blooms deplete oxygen in lakes, produce toxins, and end up killing aquatic life in the lake. Researchers are tracing the role of bird feces, which are rich in phosphorus and nitrogen.
BPA is a chemical that is used in a variety of consumer products, such as food storage containers and water bottles. In previous studies, researchers at the University of Missouri, Westminster College and the Saint Louis Zoo, determined that BPA can disrupt sexual function and behavior in painted turtles. Now, the team has identified the genetic pathways that are altered as a result of BPA exposure during early development.
A study led by Dr. YUE Xu from CAS Institute of Atmospheric Physics provides the first systematic assessment of the effects of ozone and aerosol haze pollution on terrestrial ecosystem health and land carbon assimilation in China, for the present day and two possible future scenarios.
Water reservoirs created by damming rivers could have significant impacts on the world's carbon cycle and climate system that aren't being accounted for, a new study concludes.
