Bias distribution and regulation in photoelectrochemical overall water-splitting cells
The photoelectrochemical (PEC) overall water-splitting reaction (OWS) has been fully developed in the past decade, especially in new catalysts, characterization methods and reaction mechanisms. Compared with the hydrogen evolution reaction (HER), the.....»»
Novel covalent organic framework can remove a dangerous "forever chemical" from drinking water
Researchers at NYU Abu Dhabi (NYUAD) have developed an innovative cationic covalent organic framework (COF) that efficiently detects and removes perfluorooctanoic acid (PFOA), a harmful and persistent pollutant, from drinking water. This breakthrough.....»»
Unique microbial communities discovered beneath frozen surface of Antarctica"s Lake Enigma
An international team of polar researchers has found several types of microbiota living in the water below the frozen surface of Antarctica's Lake Enigma. In their study, published in the journal Communications Earth & Environment, group members vent.....»»
Research introduces "ecology stereotypes," how perceptions are influenced by others" backgrounds
In new research published in the Journal of Personality and Social Psychology, Oliver Sng, UC Irvine assistant professor of psychological science, presents findings that could transform how we understand the origins of stereotypes and social bias......»»
New synthetic receptor expands cellular control options, including immune response and neurological signaling
A basic function of cells is that they act in response to their environments. It makes sense, then, that a goal of scientists is to control that process, making cells respond how they want to what they want......»»
Recycling sewage is a sensible way to improve water security, but would you swallow it?
Our water supply is far from infinite. According to the UN, nearly 1.8 billion people are projected to live in areas with absolute water scarcity by 2025, and two-thirds of the world's population could be living under water-stressed conditions......»»
Liquid water molecules are inherently asymmetric: New insight into the bonds between water molecules
Icebergs float on water because the underlying liquid water has a higher density than the iceberg. Liquid water itself has its highest density at 4°C—one of the so-called anomalies of water, i.e. properties of liquids that are rarely observed for.....»»
New pathway found for regulating zinc in E. coli
Cornell researchers have discovered a pathway by which E. coli regulates all-important zinc levels, an insight that could advance the understanding of metal regulation in bacteria generally and lead to antibacterial applications such as in medical in.....»»
Discovery of molecular switch explains how bacteria control their protein biosynthesis through cell metabolism
Protein biosynthesis—the process whereby cells produce protein molecules, which are essential for life and growth—is a highly complex and strictly regulated affair. An interdisciplinary team led by LMU biologist PD Dr. Jürgen Lassak has now disc.....»»
70% of open-source components are poorly or no longer maintained
The geographic distribution of open-source contributions introduces geopolitical risks that organizations must urgently consider, especially with rising nation-state attacks, according to Lineaje. Open-source code risks rise with anonymous contributi.....»»
Splash pads really are fountains of fecal material; CDC reports 10K illnesses
A big problem is leaky swim diapers and kids sucking up recirculated water. There's nothing quite like a deep dive into the shallow, vomitous puddles of children's splash pads. Ev.....»»
Team links comet water to Earth"s oceans
Researchers have found that water on Comet 67P/Churyumov–Gerasimenko has a similar molecular signature to the water in Earth's oceans. Contradicting some recent results, this finding reopens the case that Jupiter-family comets like 67P could have h.....»»
Decoding protein interactions to better understand how mutations contribute to disease
Investigating how proteins interact is key to understanding how cells work and communicate. In a new study published in Nature Communications, FMI researchers have provided key insights into how protein interactions are governed and how mutations inf.....»»
Streams near farms emit high levels of greenhouse gas, studies find
In the upper reaches of a Minnesota watershed, the water is so full of dissolved nitrous oxide that University of Illinois Urbana-Champaign hydrologist Zhongjie Yu likens it to a soda can......»»
Report finds poor local management and climate change amplified Hurricane Helene"s impacts
A new analysis by the United Nations University Institute for Water, Environment, and Health (UNU-INWEH) reveals alarming statistics about the catastrophic impacts of Hurricane Helene on 26 September 2024. This powerful Category 4 hurricane claimed 2.....»»
Nanoscale bumps and grooves trigger big changes in cell behavior
The surfaces that cells come into contact with can influence how the cells grow, function, and communicate—shaping metabolism and even cellular health. Now, engineering researchers at the University of California San Diego have developed a platform.....»»
Swelling streams—climate change can cause more sediment in high-mountain rivers
Many high-mountain rivers in Asia transport more sediment downstream compared to a few years ago. Changes in sediment levels have a particularly strong impact on agriculture, water quality, flood management, and hydropower generation......»»
Research offers insights into Permian Basin earthquake hazards
A new collection of published papers offers the most detailed and comprehensive breakdown yet of how water injected into the Permian Basin during oil and gas operations is changing subsurface pressures and causing earthquakes......»»
"Forever chemicals" are polluting African waters
Every week seems to bring a new report about where "forever chemicals" have been found: in soil, drinking water, our bodies and marine animals. Their proper scientific name is perfluoroalkyl and polyfluoroalkyl substances (PFAS). But they're more com.....»»
Scientists develop self-sustained protein transport and tissue assembly in artificial cells
In a new Nature Communications study, scientists have developed a novel method for artificial cells to interact with their external environment without the need for complex modification processes......»»
Cool water from the deep could protect pockets of the Great Barrier Reef into the 2080s
For coral reefs, climate change is an existential threat. Australia's Great Barrier Reef has endured seven mass bleaching events over the past 25 years. Five have occurred in the past eight years......»»
