How a drought affects trees depends on what’s been holding them back
Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.
Identifying the bee’s knees of bumble bee diets
A new study has identified the bee's knees of bumble bee dietary options in Ohio and the Upper Midwest. By viewing almost 23,000 bumble bee-flower interactions over two years, researchers found that these bees don't always settle for the most abundant flowers in their foraging area -- suggesting they have...
What you count is not necessarily what counts
Seawater is full of bacteria, hundreds of thousands live in every liter. But the sheer number of bacteria living in the water does not necessarily mean a lot. More important is how active they are and how quickly they duplicate.
A multiomics approach provides insights into flu severity
Researchers were able to identify changes in the accessibility (that is, the 'readability') of transposable elements. To do this, the researchers used an approach combining various sets of multiomics data, which characterize and quantify collections of biomolecules in cells or organisms. One was the transcriptome, which consists of all copies...
Fine particulate matter catalyzes oxidative stress in the lungs
Study sheds new light on the adverse health effects of air pollution: hydrogen peroxide production of fine particles may not be as important as previously assumed. A new study reveals that the adverse health effects of fine particulate matter (PM2.5) are attributable to the conversion of peroxides into more reactive...
New insights into the complex neurochemistry of ants
Ants' brains are amazingly sophisticated organs that enable them to coordinate complex behavior patterns such as the organization of colonies. Now, researchers have developed a method that allows them to study ants' brain chemistry and gain insights into the insects' neurobiological processes. The findings could help to explain the evolution...
Dinosaurs were the first to take the perspectives of others
Understanding that others hold different viewpoints from your own is essential for human sociality. Adopting another person's visual perspective is a complex skill that emerges around the age of two. A new study suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in...
New supply chain model to empower seabound hydrogen economy
A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.
Nitrate: Healthy heart or cancer risk? Meet nutrition’s Jekyll and Hyde
For a long time nitrate has been viewed warily, with previous research showing it could potentially be linked to causing cancer. However, it has subsequently bee revealed to have various cardiovascular health benefits. So, which is it? A new review of dietary nitrate research shows the answers to its health...
