Researchers at the University of Illinois have developed a new technique to determine the atomic-scale structure of membrane proteins using solid-state nuclear magnetic resonance spectroscopy. This breakthrough enables high-resolution structural information, which is crucial for understanding protein function.
Researchers at Ohio State University developed synthetic molecules based on curcumin to kill cancer cells and stop cell spread. The compounds show promise in treating 50% of breast and prostate cancers, with potential applications in pancreatic cancer as well.
Researchers have successfully sequenced the complete genome of a microbe that eats methylamine, a form of ammonia, using lake mud as a sample. The study showcases a new method for discovering unknown organisms and has significant implications for understanding ecological cycles and monitoring microbial population shifts.
A previously unrecognized group of air pollutants has been discovered that can cause life-threatening conditions similar to those found in tobacco smoke. Inhaling these pollutants exposes individuals to potentially lethal amounts of free radicals, with the average person inhaling 300 times more daily than from smoking one cigarette.
Researchers at Rensselaer Polytechnic Institute have developed a fully synthetic heparin alternative that is safer and more pure than traditional heparin. The new version uses a process called chemoenzymatic synthesis to replicate the natural biosynthesis of heparin, resulting in a higher dose and lower risk of contamination.
Researchers at Mount Sinai School of Medicine have developed a new gene silencing technology that can effectively suppress transcriptional expression of targeted genes in human cells, including those linked to various diseases. This breakthrough could pave the way for preventing diseases where gene dysfunction plays a role.
Researchers have made a breakthrough in developing a safer, fully-synthetic version of heparin, a widely used blood thinner currently produced from pig intestines. The new synthesis method uses powerful enzymes to produce the pure heparin polymer, boosting production a million times higher than previous methods.
A study published by the American Psychological Association found that people taking antidepressants drive worse than those who aren't taking such drugs. Depressed drivers on meds performed significantly poorer in a driving simulation test.
A recent survey found that over half of college students reported having at least one episode of suicidal thinking, while 15% seriously considered attempting suicide. The study suggests that interventions should be offered at multiple points, not just during crisis, to address the entire continuum of suicidal thoughts and behaviors.
Researchers at Carnegie Mellon University developed hydrogels that promote the growth of pre-osteoblast cells, aiding bone development. These gels interact with growth factors like demineralized bone matrix, providing scaffolding for bone cell proliferation and new tissue formation.
Researchers successfully controlled an electrical current using the 'spin' within electrons, a step toward building plastic semiconductor switches. However, highly efficient organic LEDs may only convert up to 25 percent of electricity into light, contrary to earlier estimates.
Researchers develop new technology to analyze hair interactions, finding that mechanical and chemical changes cause rough feel. The study aims to optimize hair care product formulas by understanding how different components affect hair-to-hair interactions.
A new study found biracial Asian Americans are twice as likely as monoracial peers to be diagnosed with a psychological disorder. The research controlled for factors like age and stress but found no difference in life experiences.
A large genetic analysis implicates machinery involved in sodium and calcium balance in brain cells in bipolar disorder. Variation in two genes showed the strongest association with bipolar disorder.
A novel approach extracts single genomes and discerns specific microbial capabilities from mixed community sequence data. The research team characterized biochemical pathways associated with nitrogen cycling and methane utilization in Lake Washington sediments, revealing novel versions of metabolism.
The study found a significant decrease in child pneumonia mortality rates after introducing improved oxygen systems, with a 35% lower risk of death. The cost-effectiveness of this system was also compared to other public-health interventions, with favorable results.
The APA task force report highlights the importance of positive attitudes, racial identity, and family support in promoting resilience among African-American youth. The report identifies four key themes: active engagement, flexibility, communalism, and critical-mindedness.
Researchers found adults are more effective at identifying false reports than detecting false denials of actual events. This discovery has significant implications for forensic child abuse evaluations and highlights the importance of evaluating children's reports.
Researchers at Vanderbilt University Medical Center have successfully recovered antibodies to the 1918 flu virus from elderly survivors, showcasing surprisingly long-lasting immunity. These antibodies could serve as a treatment option if another similar strain emerges in the future.
New research reveals that infection with the 1918 influenza virus granted survivors lifelong protection against the disease. Antibodies produced by these individuals proved effective in blocking the viral infection in mice.
Research shows that video games enhance cognitive and perceptual skills in children and adults, with benefits seen in classrooms, surgical procedures, and scientific thinking. Studies also reveal varied effects of game content and player behavior on learning outcomes.
The American Psychological Association has adopted a resolution supporting full equality for transgender and gender-variant individuals, calling for appropriate, nondiscriminatory treatment. The association's Task Force on Gender Identity and Gender Variance recommends further research into all aspects of gender identity and expression.
A recent study by University of California, Davis researchers found that Asian Americans with high levels of family conflict are three times more likely to attempt suicide than those without such conflicts. The risk is independent of depression and income levels.
