Trees set sixth-graders up for success
The transition to middle school is undeniably tough for many sixth-graders, even in the best of times.

Yin and Yang: Two signaling molecules control growth and behavior in bacteria
Bacteria are considered to be true experts in survival. Their rapid adaptive response to changing environmental conditions is based, among other things, on two competing signaling molecules. As the 'Yin and Yang' of metabolic control they decide on the lifestyle of bacteria, as reported by researchers from the University of Basel. The new findings also play a role in the context of bacterial infec

Europa glows: Radiation does a bright number on Jupiter's moon
As the icy, ocean-filled moon Europa orbits Jupiter, it withstands a relentless pummeling of radiation. Jupiter zaps Europa's surface night and day with electrons and other particles, bathing it in high-energy radiation. But as these particles pound the moon's surface, they may also be doing something otherworldly: making Europa glow in the dark.

A biomimetic membrane for desalinating seawater on an industrial scale
The treatment of seawater, including its large-scale desalination, is a major challenge for our society. Reverse osmosis is one of the most widely used techniques for the desalination of water. Some of the membranes currently used are artificial channels of water inserted into lipid layers. But their large-scale performance is not satisfactory under real osmotic pressure and salinity conditions.

Cell aging can be slowed by oxidants
At high concentrations, reactive oxygen species—known as oxidants—are harmful to cells in all organisms and have been linked to aging. But a study from Chalmers University of Technology, Sweden, has now shown that low levels of the oxidant hydrogen peroxide can stimulate an enzyme that helps slow down the aging of yeast cells.
