Caveolin binding motif in Na/K-ATPase is required for stem cell differentiation, organogenesis in animals New findings reveal the importance of the Na/K-ATPase protein in stem cell differentiation and organogenesis, in a study led by scientists at Marshall University that involves the scaffolding function of the Na/K-ATPase.
These tiny, self-assembling traps capture PFAS University at Buffalo chemists have shown that self-assembling molecular traps can be used to capture PFAS—dangerous pollutants that have contaminated drinking water supplies around the world.
A potential explanation for urban smog: Aerosol particle growth higher in cold climates The effect of nitric acid on aerosol particles in the atmosphere may offer an explanation for the smog seen engulfing cities on frosty days. Under laboratory conditions, researchers at CERN in Switzerland observed the formation of atmospheric aerosols and discovered new information on the link between nitrogen oxides originating in traffic and the energy industry, and the climate and air quality. These findings were published in the Nature and Science Advances journals.
Artificial intelligence reveals mechanism for kin selection in a wild primate More like mom or dad? Human babies always get this curious look on their face combined with the question whom the child resembles most. The answers vary depending on the degree of kinship, gender and the time of assessment. Mandrills, monkeys living in Equatorial Africa, may recognize facial features coding relatedness better than humans. Scientists at the German Primate Center—Leibniz Institute for Primate Research in Göttingen, together with colleagues from the Institut des Sciences de l'Evolution de Montpellier (ISEM), showed by using up-to-date artificial intelligence (AI) that half-sisters, who have the same father look more alike than half-sisters who share the same mother. The paternal half-sisters also have closer social relationships with each other than unrelated mandrills. This result provided the first evidence suggesting that interindividual resemblance has been selected to signal paternal kinship. The study is reported in Sciences Advances.
Initial Upper Paleolithic technology reached North China by around 41,000 years ago A wave of new technology in the Late Paleolithic had reached North China by around 41,000 years ago, according to a study published May 27, 2020 in the open-access journal PLOS ONE by Fei Peng of the Minzu University of China, Beijing and colleagues.
Exploring the use of 'stretchable' words in social media An investigation of Twitter messages reveals new insights and tools for studying how people use stretched words, such as "duuuuude," "heyyyyy," or "noooooooo." Tyler Gray and colleagues at the University of Vermont in Burlington present these findings in the open-access journal PLOS ONE on May 27, 2020.
