Scientists elucidate substrate recognition and proton coupling mechanism of transporter protein VMAT2
Vesicular monoamine transporter 2 (VMAT2) is the only transporter protein in the central nervous system that mediates the storage of monoamine neurotransmitters. It plays a critical role in mediating nerve impulse transmission and neuroprotection......»»
Scientists explore how single-atom catalysts impact water purification in advanced oxidation process
The rapid increase in global industrialization in the past centuries has resulted in the disposal of excessive toxic pollutants into the environment, seriously threatening the aquatic ecosystem and human health. Peroxymonosulfate-based advanced oxida.....»»
Speeding up calculations that reveal how electrons interact in materials
Materials scientists and engineers would like to know precisely how electrons interact and move in new materials and how the devices made with them will behave. Will the electrical current flow easily within the material? Is there a temperature at wh.....»»
Researchers create the world"s strongest ionizing terahertz radiation
Terahertz waves, known as non-ionizing radiation, can turn into ionization radiation when sufficiently many terahertz photons are focused in space and time. A team led by scientists in Korea and the U.S. has created the world's most intense terahertz.....»»

Scientists uncover a multibillion-year epic written into the chemistry of life
The origin of life on Earth has long been a mystery that has eluded scientists. A key question is how much of the history of life on Earth is lost to time. It is quite common for a single species to "phase out" using a biochemical reaction, and if th.....»»
Global activity of seafloor biodiversity mapped for the first time
A team of scientists from the U.S. and the U.K. has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world......»»
New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost
As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gases to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from thes.....»»
Q&A: Plastic waste is a global problem, but carbon recycling can help
Heavy industries such as aviation and chemical manufacturing contribute to about 20% of overall U.S. greenhouse gas emissions and will continue to depend on fossil fuels......»»
DNA analysis reveals that there are more species of parasitoid wasps than anticipated
When Charles Darwin first encountered parasitoid wasps, he was horrified. In an 1860 letter to American botanist Asa Gray, he wrote: "I cannot persuade myself that a beneficent and omnipotent God would have designedly created parasitic wasps with the.....»»
