A team of researchers has developed a novel method for repairing soft-tissue organs and tissues using aqueous solutions of nanoparticles. In vivo experiments on rats showed that the method can close deep wounds rapidly without inflammation or necrosis, and successfully repair difficult-to-suture organs such as the liver.
A new study by Stanford researchers challenges the long-accepted island biogeography theory, which predicts a decline in species abundance in fragmented landscapes. Instead, they found that farmland and forest remnants in human-dominated landscapes can support higher species diversity and slow extinction rates.
A study published in Psychiatry Research found that dopamine replacement therapy commonly used to treat motor symptoms of Parkinson's disease was associated with a decline in cognitive performance among depressed Parkinson patients. Mood in depressed Parkinson's patients was also worse while on dopaminergic medications.
A mid-level solar flare, peaking at M7-class, was emitted by the sun on April 18, 2014. The radiation burst did not affect humans on Earth but may disturb communications signals and GPS.
Scientists at Cornell University have successfully switched a particular transition metal oxide from a metal to an insulator by making it less than a nanometer thick. This breakthrough discovery has the potential to revolutionize the development of ultra-thin electronic devices.
Asteroid and comet impacts can preserve the signatures of ancient life in Earthly impact debris. Researchers found fragments of leaves and preserved organic compounds in ancient impact glasses from Argentina, which could provide a snapshot of environmental conditions at the time of those impacts.
A new defense framework will be developed by UT Dallas professor Dr. Zhiqiang Lin to detect, diagnose and repair kernel malware attacks and enforce a prevention mechanism. The framework aims to detect malicious code sequences in the core of computer operating systems and prevent kernel malware infections.
A survey of emergency contraceptive pills in Peru found that 28% were either substandard or falsified, posing serious health risks. Researchers developed a sophisticated approach using mass spectrometry to detect counterfeit drugs, highlighting a growing concern for women's health in developing nations.
A study in the American Journal of Preventive Medicine found that people tend to think more about their health at the beginning of the week, with search volumes peaking on Mondays and Tuesdays. The researchers believe this pattern may be due to a desire for a 'health reset' after weekend indulgences.
Recent research suggests that domestication may be more complex than previously thought, with many species being domesticated less than expected. Studies on animal and plant domestication highlight the limitations of human agency in shaping organisms through selective breeding.
Physicists at Harvard University have successfully created quantum switches that can be turned on and off using a single photon. This technological achievement could lead to the creation of highly secure quantum networks, enabling perfectly secure communications over long distances.
Research by Baylor University and the University of Texas-San Antonio found that listening to gospel music decreases anxiety about death, while increases sense of control among seniors. The study, based on a nationwide survey, also showed positive associations between religious music and life satisfaction, self-esteem.
A new study found that chronic inflammation in non-cancerous prostate tissue may increase a man's risk of developing high-grade prostate cancer by nearly twice. The study showed that men with signs of chronic inflammation had a higher risk of having an aggressive and rapidly growing prostate cancer.
Researchers funded by NSF discover that some landscapes underlying the massive Greenland ice sheet may have remained undisturbed for almost 3 million years. The team analyzed chemical composition of silts from an ice core and found evidence of a continuous cover of Summit, Greenland, with minimal surface erosion during warmest periods.
A team of researchers found that some studies have shown no-till systems without cover crops may not increase soil organic carbon stocks as claimed. The review suggests that different definitions and methods can lead to conflicting findings, and the accuracy of determining soil organic carbon sequestration depends on the method used.
Researchers at UMass Amherst have developed a new version of Geckskin, a gecko-like adhesive that can adhere to various surfaces like drywall and wood. The material exhibits the ability to stick and release on different surfaces, opening up possibilities for innovative technologies in homes, offices, or outdoors.
A study analyzing ancient chicken DNA found that traits like yellow skin only became widespread in the last 500 years, contradicting previous assumptions about domestication. Researchers compared DNA from 81 ancient chickens to those of modern chickens, revealing significant genetic differences.
Researchers Jonathan Powell, G. William Wong, and Elias Zambidis will explore novel treatments for diabetes using protein design, hormone discovery, and stem cell therapy.
A study found that chronic inflammation in benign prostate tissue was associated with high-grade prostate cancer. Men with at least one biopsy core showing inflammation had a 1.78 times higher odds of having prostate cancer and a 2.24 times higher odds of having aggressive disease.
Researchers found that seed dormancy allows plants to adapt to their environment, resulting in increased species diversity. Plants with this ability are more likely to colonize new areas and thrive under changing conditions, a strategy that has been around since the earliest seeds.
A recent study by North Carolina State University reveals that impurities can either hinder or improve the performance of a key superconductive material, Bi2212. The size of the impurities determines their effect, with nanoscale defects appearing to enhance superconductivity, while large-scale impurities weaken it.
A team of scientists discovered a 3-million-year-old tundra landscape preserved under the Greenland Ice Sheet, suggesting the ice sheet has endured for longer than previously known. The findings indicate that even during warm periods, the center of Greenland remained stable, preventing the complete melting of the ice sheet.
Researchers found that thinking about non-emotional contextual details of a memory can alleviate the negative effects of these memories. This strategy, known as focusing on context, is a promising alternative to other emotion-regulation strategies.
A new study by Harvard neuroscientists reveals that myelin, the electrical insulating material in nerve cells, is not uniformly distributed along axons. Instead, more evolved neurons in the cerebral cortex have intermittent myelin patterns, which may enable increased neuronal communication and complex behavior.
Scientists at Harvard University have created a magnetic resonance imaging (MRI) system that can produce nano-scale images, potentially allowing researchers to peer into the atomic structure of individual molecules. The system uses a miniaturized magnet and quantum computing technology to achieve high spatial resolution.
Researchers found that different LED light sources render white differently, affecting product appearance. Participants struggled to distinguish between cards under blue-pumped LEDs, highlighting the need for spectrum engineering to accurately render whiteness.
A research team led by Dr. Zeng Li has discovered a novel function of the Amyloid Precursor Protein (APP), which controls the growth and maturation of newborn brain cells. This finding may help researchers understand how APP goes awry in Alzheimer's disease and potentially lead to innovative therapeutics.
