Resistance to pesticides has increased in nearly a thousand pest species, including insects, weeds, and fungi. Entomologists updated definitions for key terms related to resistance to facilitate understanding and management of the issue.
Researchers at Cold Spring Harbor Laboratory demonstrate a way to observe the activity of inhibitory neurons linking sense of smell with memory and cognition in awake mice. These granule cells provide feedback to alter sensory interpretation based on past experiences.
Scientists at Stanford University have developed a new, potentially clean catalyst that can convert hydrogen and carbon dioxide into methanol with fewer side-products. The nickel-gallium catalyst offers promise for low-cost, low-pressure methanol production using renewable energy sources.
Scientists at UC San Diego School of Medicine have made a breakthrough discovery on the fate determination of T lymphocytes during an infection. They found that individual cells can make decisions about whether to become effector or memory cells almost immediately after exposure to a pathogen, suggesting that this process could be cruc...
Children who outgrow one type of food allergy may develop another, more severe type to the same food. Eosinophilic esophagitis (EoE) can cause swelling and inflammation in the esophagus, leading to symptoms like weight loss and swallowing difficulties.
A study of 1,125 domestic violence victims found that those whose partners were arrested were 64% more likely to die early compared to those who received a warning. Employed black victims suffered the worst effects, with mortality rates over four times higher than those whose partner received a warning.
Current flood losses in Europe are likely to double by 2050, with socioeconomic growth accounting for two-thirds of the increased risk. Climate change is also expected to contribute to this increase, as changing rainfall patterns affect river flow and flood frequency.
A study by McGill University researchers shows that climate change has led to a decrease in ocean salinity, creating a freshwater lid that prevents mixing with warm waters underneath. This has resulted in the suppression of naturally rare events like the Antarctic polynya and contributed to the shrinking of Antarctic Bottom Water.
A scientific team discovered how the immune system makes a powerful antibody that blocks HIV infection of cells by targeting a site on the virus called V1V2. The new findings point toward a potentially more effective vaccine that would generate V1V2-directed HIV neutralizing antibodies.
ICFO researchers develop plasmonic nano-tweezers that trap and manipulate nano-scale objects without mechanical contact, enabling 3D displacement. This technique has potential applications in medicine and nanotechnology.
Columbia researchers have developed a novel method to image small biomolecules, such as drugs and nucleic acids, in living cells without disturbing their functions. By using stimulated Raman scattering microscopy with alkyne tags, they can obtain high detection specificity and sensitivity.
Researchers at NUS created a highly sensitive fluorescence probe to detect Monoamine Oxidase B (MAO-B) activity, which is elevated in patients with Parkinson's disease. The probe can monitor the progression of the disease and has potential as a biomarker.
An international team has identified genetic mutations that reduce the risk of type 2 diabetes by 65% in people with risk factors. These mutations may lead to the development of a new therapeutic strategy for preventing and treating the disease.
A new sensor can measure antibiotic levels in blood with high sensitivity, enabling individualized treatment and reducing potential toxic effects. This development has the potential to improve clinical regimes and combination therapies.
Scientists from Queen Mary University of London developed a novel method to quantify plant tolerance to high light intensity. The study found that plants grown without quick responses to high light had reduced capacity to protect themselves from damage.
