Phys.org / Mosquitoes learn to link the smell of DEET with a blood meal, new study finds
Mosquito repellents are key to protecting ourselves from mosquito bites and the pathogens they might carry. The most widely used active ingredient in insect repellents is N,N-diethyl-meta-toluamide, commonly known as DEET.
Science X / As climate change redraws rainfall maps, some regions face a far greater flood risk than others
As the climate warms, heavy downpours are covering more ground—but where exactly? A new study puts the big-picture changes in context, and suddenly, it matters what region you live in.
Medical Xpress / Five minutes of prayer reduces pain and anxiety in primary care patients, randomized trial finds
A randomized controlled trial conducted at the University of Maryland School of Medicine has found that a five-minute session of proximal intercessory prayer (PIP)—in-person prayer offered by a trained volunteer—significantly ...
Phys.org / Living brain gene activity revealed noninvasively through programmable blood test
Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when messenger RNA (mRNA) makes copies of active genes; and translation, when mRNA guides protein assembly.
Science X / Why does stress let your brain learn but prevent you from thinking logically?
The human brain is an incredible processor that can take existing knowledge, such as old memories and experiences, and weave it with newly acquired information to help us draw conclusions and make decisions crucial to navigating ...
Medical Xpress / Smartphone app helps those with advanced cancer maintain quality of life
A smartphone app can help individuals with advanced cancer deal with symptoms and maintain their quality of life, according to new research.
Medical Xpress / AI helps accelerate breast cancer diagnosis for high-risk women
Women with abnormal mammograms often have to wait for weeks to find out whether they have breast cancer. Now, researchers at UC San Francisco and UC Berkeley have found a way to help reduce the wait and the worry by using ...
Dialog / Bridged or not? Scientists uncover a key step in hydrogenase assembly
How does nature build one of the most sophisticated catalytic metal centers found in biology? An international team of researchers has now resolved a long-standing debate surrounding the assembly of the active site of [FeFe]-hydrogenases—enzymes ...
Tech Xplore / AI and ultralow-energy lasers enable an ultrafast authentication system
The security of modern communications heavily relies on systems that can rapidly and reliably verify users and the devices they are using. This process, known as authentication, essentially entails confirming that users or ...
Medical Xpress / New 3D map of the heart's electrical wiring can help patients with congenital heart disease
Researchers from UCL (University College London) and the ESRF (The European Synchrotron) have produced the first three-dimensional map of the heart's electrical wiring in Tetralogy of Fallot, one of the most common congenital ...
Medical Xpress / How the brain predicts social interaction before it starts
How does the brain decide to approach others? Researchers have found that coordinated brain activity linked to social behavior begins seconds before movement starts. In a study using zebrafish, they identified a key role ...
Phys.org / Precise polymer 'knots' uncover hidden slack for designing ultra-tough and responsive smart materials
From household plastic packaging to the flexible frameworks that support wearable electronics, polymer materials form the invisible backbone of modern life. At a microscopic level, polymers consist of long, ribbon-like molecular ...
