Scientists are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen. The new microcapsules burst when exposed to light, releasing their contents in ways that could have wide-ranging commercial uses from home and personal care to medicine.

Individuals who consume a diet high in sodium or artificially sweetened drinks are more likely to experience a decline in kidney function, according to two new articles.
Isotopic measurements performed on fossil land snail shells found in ancient soils on the subtropical eastern Canary Islands resulted in oxygen isotope ratios that suggest the Spanish archipelago off the northwest coast of Africa has become progressively drier over the past 50,000 years, according to new research.
Researchers have taken a snapshot of proteins changing shape, sticking together and creating structures that are believed to trigger deadly processes in the nervous system. The discovery opens the possibility of designing drugs for a devastating neurological disease, amyotrophic lateral sclerosis (ALS).

Security Measures Lead To False Sense Of Security: Scientists Dispute Use Of National Security Tools
Many of the security tools used by national governments lack scientific underpinning, according to an expert.
Biologists have shown that independent but similar molecular changes turned a harmless digestive enzyme into a toxin in two unrelated species — a shrew and a lizard — giving each a venomous bite.
Pregnant women who catch the flu are at serious risk for flu-related complications, including death, and that risk far outweighs the risk of possible side effects from injectable vaccines containing killed virus, according to an extensive review.

Using precision techniques for making superconducting thin films layer-by-layer, physicists have identified a single layer responsible for one such material’s ability to become superconducting, i.e., carry electrical current with no energy loss. The technique could be used to engineer ultrathin films with “tunable” superconductivity for higher-efficiency electronic devices.
Each year, the influenza virus evolves. And each year, public health officials try to predict what the new strain will be and how it will affect the population in order to best combat it. A new study may make their task a little easier. The study breaks ground by working across scales and linking sub-molecular [...]
