The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as vehicle electrification speeds up and nations work to reduce greenhouse gas emissions through mid-century. This surge in demand will also create a variety of economic and supply-chain problems, according to new research.

Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can...

Researchers develop a computational model of stormwater piping to study storm geysers. They used this model to understand why storm geysers form, what conditions tend to make them worse, and what city planners can do to prevent them from occurring. The authors say the best cure for a storm geyser is bigger pipes; however, that advice is little help to cities with existing pipeline infrastructure....

The exact mechanism of cartilage breakdown in osteoarthritis is unknown, but damage from mechanical stress with insufficient self-repair is believed to be the main culprit. The composition of synovial fluid, or joint lubricant, changes significantly: The concentration and molecular weight of hyaluronic acid tends to decrease. Researchers explore the disease-driven breakdown of hyaluronan and the...

Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.

Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The device is expected to help next-generation wireless communication technologies efficiently convey data in an environment that is becoming crowded with signals.

Researchers have developed a model that detects workplace stress just by how people type and move their computer mouse. This might enable employees to prevent chronic stress early on.

Among Indigenous, rural non-industrial populations inhabiting the tropical forests of lowland Bolivia, researchers report, there appears to be an optimal balance between levels of food consumption and exercise that maximizes healthy brain aging and reduces the risk of disease.

New research has identified characteristics of aggressive driving -- which impact both road users and the transition to self-driving cars of the future.

A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.

A small amount of a perfume component -- nonanal -- added to a traditional blend of sex pheromones captures the attention of male fall armyworm moths looking for a good time.

Researchers have found a creative way to make a vaccine for norovirus, the leading cause of foodborne infections, by piggybacking on rotavirus, an unrelated virus for which there are already several highly effective vaccines.

Research by the Atacama Cosmology Telescope collaboration has culminated in a groundbreaking new image that reveals the most detailed map of dark matter distributed across a quarter of the entire sky, reaching deep into the cosmos. Findings provide further support to Einstein's theory of general relativity, which has been the foundation of the standard model of cosmology for more than a century,...

Researchers from around the world have sought to answer important questions about the most basic laws of physics that govern our universe. Their experiment, the Majorana Demonstrator, has helped to push the horizons on research concerning one of the fundamental building blocks of the universe: neutrinos.

The island of Dominica took a direct hit from Category 5 Hurricane Maria. Nine months afterward, researchers found that while 89% percent of trees located in nine previously documented forest stands were damaged, but only 10 percent had immediately died. The most common damage was stem snapping and major branch damage. The damage with the highest rates of mortality were uprooting and being crushed...

The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, depending on their unique temperature, light and flow. To better understand which factor has the greatest impact on the concentration of dissolved oxygen, researchers used a deep learning model to analyze...

A new study's finding that urban light pollution may disrupt the winter dormancy period for mosquitoes that transmit West Nile virus could be considered both good news and bad news. The good news is that the disease-carrying pests may not survive the winter if their plans to fatten up are foiled. The bad news is their dormancy period, known as diapause, may simply be delayed -- meaning they're...

Researchers have identified a new circuit element known as a meminductor.

Scientists have discovered over 30,000 viruses by using the high-performance computer cluster 'Leo' and sophisticated detective work. The viruses hide in the DNA of unicellular organisms. In some cases, up to 10% of microbial DNA consists of built-in viruses.

Researchers discovered that males of the yellow crazy ant have maternal and paternal genomes in different cells of their body and are thus chimeras.

Research shows flooding events in the province have doubled in the last century.

To survive, all organisms must regulate their appetite. Hormones and small proteins called neuropeptides perform this process, stimulating feelings of hunger and fullness. When researchers noted the similarities between GAWamide, a neuropeptide that regulates feeding in the Cladonema jellyfish, and myoinhibitory peptide, a neuropeptide that regulates feeding in fruit flies, they decided to test...

Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.

Gossip influences if people receive advantages whether they work in an office in the U.S. or in India -- or even in a remote village in Africa, a new study found. In a set of experiments, anthropologists found that positive and negative gossip influenced whether participants were willing to give a person a resource, such as a raise or a family heirloom, especially when the gossip was specific to...
