Researchers found widespread overactivation in brain activity in unmedicated children with anxiety disorders. Treatment with cognitive behavioral therapy (CBT) led to improved clinical functioning and reduced activation in many brain areas. The findings illuminate the brain mechanisms underlying the acute effects of CBT to treat one of the most common mental disorders in children.
The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.
Scientists have found a way to reprogram T cells to fight aging. After using them to eliminate specific cells in mice, the scientists discovered they lived healthier lives and didn't develop aging-associated conditions like obesity and diabetes. Just one dose provided young mice with lifelong benefits and rejuvenated older mice.
More than half (51%) of respondents in a 2023 Harris Poll survey conducted on behalf of the American Heart Association did not identify heart disease as the leading cause of death in the U.S. Heart disease has been the leading cause of death in the U.S. for 100 years. Heart disease along with stroke, which is the fifth leading cause of death, claimed more lives in 2021 in the U.S. than all forms of cancer and chronic lower respiratory disease combined.
From misinformation and invisible cyber attacks, to irresponsible AI that could cause events involving multiple deaths, expert futurists have forecast how rapid technology changes may shape our world by 2040.
Scientists have called for simple, effective steps to cut the number of people bitten by venomous snakes.
MXene nanoparticle scaffolds have been shown to stimulate muscle growth, making them a promising option to treat muscle loss and damage. Now, researchers explain the molecular mechanisms behind their positive influence on muscle regeneration. This discovery can advance MXene scaffolds, potentially improving muscle reconstruction surgeries and establishing them as a standard medical practice for muscle recovery.
A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
A new mobile phone-based facial recognition application for dogs has the potential to significantly improve rabies vaccination efforts in endemic areas like Africa and Asia, according to a new study. A team used the app to test its effectiveness at a rabies vaccination clinic in rural Tanzania where they microchipped, vaccinated and registered dogs. The technology proved remarkably accurate during a subsequent visit to surrounding villages once poor images and improperly recorded information were removed from its database. Using the app, operators identified 76.2% of vaccinated dogs and 98.9% of unvaccinated dogs.
Researchers have developed a way to use ultrasound to predict whether a pregnant person is at risk of delivering a baby prematurely, which occurs in upward of 10% of pregnancies in the U.S.
Scientists have developed a universal method for producing a wide variety of designed metallic and semiconductor 3D nanostructures -- the potential base materials for next-generation semiconductor devices, neuromorphic computing, and advanced energy applications. The new method, which uses a 'hacked' form of DNA that instructs molecules to organize themselves into targeted 3D patterns, is the first of its kind to produce robust nanostructures from multiple material classes.
Exposure to organophosphate ester flame retardants during pregnancy is linked to premature births and greater fetal growth, according to a new study.
Results of a preclinical study offer hope for new treatment options in the medium term ovarian cancer is often very aggressive and responds poorly to the therapies currently available. A recent study offers hope that this could change in the medium term. The researchers used an mRNA as a therapeutic. With its help, the tumor cells produced a protein again that prevents their own uncontrolled proliferation or induces cell death. The mRNA therapeutic successfully combated cancerous cells and tumors in vitro as well as metastases in mice.
A new study now provides a global examination of drought-pluvial volatility -- or the tendency to shift from one weather extreme to another.
Despite strict EU regulations on plastic recycling, there is little oversight on plastic waste shipped from the EU to Vietnam. A large percentage of the exported European plastic cannot be recycled and gets dumped in nature, according to recent research.
A new method predicts how much flooding a coastal community is likely to experience as hurricanes evolve due to climate change. Using New York as a test case, the model predicts Hurricane Sandy-level flooding will occur roughly every 30 years by 2099.
Researchers have presented a new study on cyberattack risks to offshore wind farms in Glasgow, United Kingdom. They looked specifically at wind farms that use voltage-source-converter high-voltage direct-current (VSC-HVDC) connections, which are rapidly becoming the most cost-effective solution to harvest offshore wind energy around the world. They found that their complex, hybrid-communication architecture presents multiple access points for cyberattacks.
Plants produce a range of chemicals known as volatile organic compounds that influence their interactions with the world around them. In a new study, researchers investigated how the type and amount of these VOCs change based on different features of tomato plants.
Engineers have created a new lithium battery that can charge in under five minutes -- faster than any such battery on the market -- while maintaining stable performance over extended cycles of charging and discharging.
Scientists have experimental evidence that the key step in protein formation can occur in droplets of pure water.
