For the first time, scientists have visualized a new class of molecular gates that maintain pH balance within brain cells, a critical function that keeps cells alive and helps prevent stroke and other brain injuries.

The world's biggest iceberg is on a collision course with a remote South Atlantic island that is home to thousands of penguins and seals, and could impede their ability to gather food, scientists told AFP Wednesday.
The United States on Wednesday formally left the triggered by his administration a year ago, further isolates Washington in the world but has no immediate impact on international efforts to curb global warming.
Scientists and graduate students with minority identities who conduct fieldwork report being stalked, followed, sexually assaulted, harassed, threatened, having guns pulled on them and police called on them.
A new Tel Aviv University study compares the effects of two types of disposable dishes on the marine environment—regular plastic disposable dishes and more expensive bioplastic disposable dishes certified by various international organizations—and determines that the bioplastic dishes had a similar effect on marine animals as regular plastic dishes. Moreover, the study finds that bioplastic...
Archaeologists from the University of Sydney have reconstructed the ancient seasonal migration routes of Bronze Age herders in Xinjiang, north-western China.
An analysis of ways to measure a community's vulnerability to climate change suggests that California's current method may leave some at-risk communities behind in efforts to reduce health impacts of extreme heat. Lynée Turek-Hankins of Stanford University (now currently at the University of Miami) and colleagues present these findings in the open-access journal PLOS ONE on November 4, 2020.
A new study demonstrates the effectiveness of a novel method for using DNA in seawater samples to determine which fish species are present in a given part of the deep sea. A team of scientists from eDNAtec Inc. and colleagues from Fisheries and Oceans Canada and Memorial University present these findings in the open-access journal PLOS ONE on November 4.
As wildlife populations decline around the globe, understanding the natural and human-induced factors that influence their growth is critical for determining the risk of population declines and developing effective conservation strategies.
Rising sea levels will affect coasts and human societies in complex and unpredictable ways, according to a new study that examined 12,000 years in which a large island became a cluster of smaller ones.
For centuries, historians and scientists mostly agreed that when early human groups sought food, men hunted and women gathered. However, a 9,000-year-old female hunter burial in the Andes Mountains of South America reveals a different story, according to new research conducted at the University of California, Davis.
The food preparation preferences of Chinese cooks—such as the technological choice to boil or steam grains, instead of grinding or processing them into flour—had continental-scale consequences for the adoption of new crops in prehistoric China, according to research from Washington University in St. Louis.
Researchers from the Institute of Industrial Science, the University of Tokyo (UTokyo-IIS) have designed novel linear nanomotors that can be moved in controlled directions using light. This work opens the way for new microfluidics, including lab-on-a-chip systems with optically actuated pumps and valves.
Earthquakes and fires compete as metaphors for contemporary California. While we await the Big One, fire keeps winning the competition. The year 2020, like 2018 before, is the worst on record—until the next worst fire year. When will the burning end? That's the wrong question. Better to ask: How can Californians learn to live with the absence of an ending?
An earthquake of magnitude 8.0 or larger will almost always cause strong shaking, but a new study suggests that smaller earthquakes—those around magnitude 5.5 or so—are the cause of most occurrences of strong shaking at a 60-kilometer (37-mile) distance.
In 2008, Cyclone Nargis killed more than 138,000 people in Myanmar. It was a powerful category 3 or 4 storm at landfall, but tropical storms with similar wind speeds that year resulted in far fewer fatalities in other countries.
Researchers from Beijing Normal University, Peking University and National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) found that there is weak correlation between fast radio bursts (FRBs) and soft gamma-ray repeater J1935+2145 (SGRs). The study was published in Nature on Nov. 4.
When it comes to safety in open-cast mining, soil stability is one of the most critical factors. Settlement of the ground or slipping of slopes poses a great risk to buildings and people. Now Mahdi Motagh from the German Research Centre for Geosciences GFZ, in cooperation with Chinese scientists, has evaluated data from the Sentinel 1 mission of the European Union's Copernicus program and thus...
Turbulence is an omnipresent phenomenon—and one of the great mysteries of physics. A research team from the University of Oldenburg in Germany has now succeeded in generating realistic storm turbulence in the wind tunnel of the Center for Wind Energy Research (ForWind).
The majority of the visible matter in the Universe consists of charged particles or plasmas which may develop magnetic field reconnection (MR) at the places where the magnetic field direction exhibits abrupt change. Through the MR the magnetic field energy may effectively be transferred into the kinetic and thermal energies of plasmas, resulting in many explosive plasma phenomena occurring on the...
A flash of luck helped astronomers solve a cosmic mystery: What causes powerful but fleeting radio bursts that zip and zigzag through the universe?
Mutants that reveal the secrets of how plants attack? No, it's not a scene from a science fiction movie, but you could be forgiven for thinking that. Instead, it's a scene from real life:
Despite extensive support for relationships between the gut microbiome and the brain (the "microbiota-gut-brain axis") in humans and rodents, little is known about these relationships in other animals, leaving questions about this system's generality.
The right indoor lighting can help set the mood, from a soft romantic glow to bright, stimulating colors. But some materials used for lighting, such as plastics, are not eco-friendly. Now, researchers reporting in ACS Nano have developed a bio-based, luminescent, water-resistant wood film that could someday be used as cover panels for lamps, displays and laser devices.
The synthesis of complex molecules such as drugs, requires a process that sometimes involves several phases that increase its cost and restrict access to the product. Now, a team at the University of Barcelona has designed a new methodological approach that combines multicomponent reactions with domino type processes—continuous transformations on a single compound—to ease the synthesis of high...
