Bacteria trapped — and terminated — by graphene filter
Chemists transform their laser-induced graphene into an air filter that not only traps pathogens but also kills them with a small blast of electricity.

The cholera bacterium can steal up to 150 genes in one go
Scientists have discovered that predatory bacteria like the cholera pathogen can steal up to 150 genes in one go from their neighbors. The study sheds light on one of the most fundamental mechanisms of horizontal gene transfer.
Read moreWas early stick insect evolution triggered by birds and mammals?
Stick and leaf insects are a strikingly bizarre group of insects with a worldwide distribution. They are famous for their impressively large body size and their remarkable ability to camouflage themselves as twigs, leaves or bark in order to hide from potential predators. A team of international researchers has now generated the first phylogenomic tree of these insects.

Scientists have long known that nodulation is important to plant health. Nodulation occurs when nodules, which form on the roots of plants (primarily legumes), form a symbiotic relationship with nitrogen-fixing bacteria that deliver nutrients to the plant. This process is a key part of sustainable agriculture and makes legumes an important source of protein for much of the world. However, recent research shows that nodulation might positively impact the plant's microbiome in other ways.

Move over Jupiter; Saturn is the new moon king. A team has found 20 new moons orbiting Saturn. This brings the ringed planet's total number of moons to 82, surpassing Jupiter, which has 79.
Early hunter-gatherers interacted much sooner than previously believed
A nearly 4,000-year-old burial site found off the coast of Georgia hints at ties between hunter-gatherers on opposite sides of North America, according to new research.
Read moreNew method gives first global picture of mutual predictability of atmosphere and ocean
Scientists have carried out a novel statistical analysis to determine for the first time a global picture of how the ocean helps predict the low-level atmosphere and vice versa. They observed ubiquitous influence of the ocean on the atmosphere in the extratropics, which has been difficult to demonstrate with dynamic models of atmospheric and oceanic circulation.
Read moreCTE risk, severity increases with years playing American football
The risk and severity of developing chronic traumatic encephalopathy (CTE) increases with the number of years playing American football according to a new study. These findings reaffirm the relationship between playing tackle football and CTE, and for the first time quantify the strength of that relationship.
