Among the extreme weather impacts resulting from climate change, drought is a growing problem around the globe, leading to frequent wildfires, threats to water resources, and greater food insecurity.
In research that could broadly benefit science, medicine and engineering, a new kind of ultrasensitive optical sensing instrument has been developed by a doctoral student at The University of Alabama in Huntsville (UAH).
Consumers should be adapting their behavior in a bid to save water during the ongoing dry weather, according to Cranfield University academics.
Stem cell scientists say they have created "synthetic embryos" without using sperm, eggs or fertilization for the first time, but the prospect of using such a technique to grow human organs for transplantation remains distant.
A trio of researchers, two with Princeton University, the other the Max Planck Institute for Biological Cybernetics, has developed a reinforcement learning–based simulation that shows the human desire always to want more may have evolved as a way to speed up learning. In their paper posted in the open-access PLOS Computational Biology, Rachit Dubey, Thomas Griffiths and Peter Dayan describe the...
Despite having 14,000 edible and nutritious plant species to choose from, 75% of the food we eat comes from just 12 plants and five animal species.
The University of Otago-led study, published today in the New Zealand Medical Journal, involved 168 12-year-olds wearing automatic cameras for four days.
In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles.
The growing trend of people feeding wild animals poses a serious risk to the well-being of humans and wildlife as new research from University College Dublin finds these feeding interactions could be driving the artificial selection of harassment behavior in some species.
Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators have reported a solar energetic particle (SEP) event observed by the Mars Energetic Particle Analyzer (MEPA) carried on China's Tianwen-1 (TW-1) spacecraft. As the first scientific report based on MEPA, the paper was published in the Astrophysical Journal Letters.

Is there a "fourth phase of water"? From time to time you might see people talking up the health benefits of so-called hexagonal water, or structured water, or exclusion-zone (EZ) water.
Do more pores in a sieve allow more liquid to flow through it? As material scientists have uncovered, this seemingly simple question may have an unexpected answer at the nanoscale—and it could have important implications in the development of water filtration, energy storage and hydrogen production.
Experts at the forefront of efforts to restore the U.K.'s coastal seagrass meadows say the remarkable plant's contribution to the most important to-do list in the history of humankind should be reassessed.
A team of researchers at Google's Quantinuum, working with a colleague at the University of Texas, Austin, has developed a way to simulate infinitely many chaotic particles using a quantum computer running with a limited number of qubits. In their paper published in the journal Nature Physics, the group describes their technique.
The SARS-CoV-2 virus, which causes COVID, originated from bats and then, probably after passing through an intermediary host, gained the ability to infect humans.
When record-breaking heat waves cause train tracks to bend, airport runways to buckle, and roads to melt, as happened in the United Kingdom last month, it is likely that business performance will suffer.
New Zealand's first climate adaptation plan, launched his week, provides a robust foundation for urgent nation-wide action.
In what's reported as a world-first achievement, biologists have grown mouse embryo models in the lab without the need for fertilized eggs, embryos, or even a mouse—using only stem cells and a special incubator.
A digital support tool on your phone can help if you want to reduce your alcohol consumption. Researchers have developed and evaluated a digital tool which helps individuals reduce their alcohol intake on their own.
New research using genome editing technology has allowed scientists to create a model and assess a gene mutation associated with neuropsychiatric disorders in humans. The study has revealed how the mutation functions in the brain and affects anxiety and sociality.
Scientists have found that elevated blood levels of an amino acid called homocysteine correlate strongly with the severity of an advanced form of non-alcoholic fatty liver disease. They also found vitamin B12 and folic acid could be used to prevent and/or delay disease progression.
As glaciers worldwide retreat due to climate change, managers of national parks need to know what's on the horizon to prepare for the future. A new study has measured 38 years of change for glaciers in Kenai Fjords National Park south of Anchorage and discovered that 13 of the 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which...
Future treatments for advanced cancer could work by sticking cancer cells in place and preventing their spread around the body. A new study by researchers at UC Davis and the University of Washington shows how an antibody strengthens bonds between cells.
New research has shown a simple pathway for stabilizing polyelectrolyte coacervate droplets that do not coalesce or deform under an electric field.
