Scientists pioneer method to tackle 'forever chemicals' (link is external)

Environmental Feed -

Researchers have developed an innovative solution to a pressing environmental challenge: removing and destroying per- and polyfluoroalkyl substances (PFAS), commonly called 'forever chemicals.' A new study unveils a method that not only eliminates PFAS from water systems but also transforms waste into high-value graphene, offering a cost-effective and sustainable approach to environmental remediation.

The proportion of harmful substances in particulate matter is much higher than assumed (link is external)

People breathing contaminated air over the course of years are at greater risk of developing numerous diseases. This is thought to be due to highly reactive components in particulate matter, which affect biological processes in the body. However, researchers have now shown that precisely these components disappear within hours and that previous measurements therefore completely underestimate the quantities in which they are present.

Scientists solve 'cocktail party' mystery of bat echolocation (link is external)

Environmental Feed -

Every night, bats emerge out of roosts in massive numbers, creating what scientists have called a 'cocktail party nightmare' of clashing echolocations. Nobody knew how bats managed this severe sensorial challenge. Now, scientists have tracked bats within a group of thousands to find out: when bats first emerge from the roost, they increase their distance from the center of the group and adjust their echolocation to maneuver safely in the areas of highest bat density.

Delicate balancing act determines how many genome gateways form in cells (link is external)

Environmental Feed -

As warehouses go, nuclei are more like libraries than bank vaults. Too many cellular components need access to the genome to lock it down like Fort Knox. Instead, large groupings of more than 1,000 individual protein molecules called nuclear pore complexes (NPCs) pepper the dividing membrane, serving as gateways for materials and messages entering and exiting the nucleus. While the basic need for this shuttle service is constant, scientists have shown that cells dynamically adjust their amounts of NPCs like a retail store opening more or fewer checkout lines throughout the day. Scientists now reveal the results of screening the entire human genome to find factors influencing how many NPCs are assembled.

Machine learning model to predict virus reservoirs (link is external)

Environmental Feed -

A new artificial intelligence tool could aid in limiting or even prevent pandemics by identifying animal species that may harbor and spread viruses capable of infecting humans. The machine learning model analyzes host characteristics and virus genetics to identify potential animal reservoirs and geographic areas where new outbreaks are more likely to occur.
