Researchers have uncovered a complete Quina technological system in the Longtan site in southwest China. The discovery challenges the widely held perception that the Middle Paleolithic period was mostly static in East Asia.
A combination of water management practices has contributed to notable groundwater gains in Central Arizona despite the region dealing with long-term water stress, according to a new study.
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.
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.
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.
A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on the fluid dynamics of cooperative feeding by Stentor, a relatively giant unicellular organism.
Researchers have developed new AI models that can vastly improve accuracy and discovery within protein science. Potentially, the models will assist the medical sciences in overcoming present challenges within, e.g. personalised medicine, drug discovery, and diagnostics.
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.
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.
One of the ocean currents in the Arctic Ocean is at risk of disappearing this century because of climate change, according to a new study. As a result, the North Atlantic could be flooded with freshwater which would weaken the global ocean circulation.
