Researchers at the University of Manchester have created a graphene 'Big Mac' structure that isolates graphene from environmental influences, allowing for better electronic properties. This breakthrough enables the potential replacement of silicon chips in computers with graphene-based transistors.
Researchers at Massachusetts General Hospital have developed a novel technique using RNA interference to block inflammation in animal models of several disorders. The technique targets specific inflammatory cells that contribute to conditions such as heart disease and cancer, reducing damage and improving survival rates.
Researchers at Harvard University have successfully controlled the rate of photon emission from luminescent imperfections in diamond, a crucial step towards developing scalable quantum networks. The breakthrough uses nitrogen-vacancy centers in diamond to emit red photons at room temperature.
Academics say a study used to justify patient choice in the NHS is fundamentally flawed and misleading. The report highlights errors in the original study and concludes that it does not prove cause or effect between patient choice and death rates.
Genome-wide studies have identified new genes involved in melanoma susceptibility, including Caspase 8 and ATM gene. The study validates regions and genes already identified as significant for melanoma, reinforcing the role of cell cycle genes like CDKN2A and CDK4.
Researchers identified a mechanism for regulating color vision by studying the fly's visual system, showing that Rhodopsins can prevent incorrect gene expression and maintain color discrimination. The findings also offer insights into how genes controlling color detection are turned on and off.
Researchers have discovered a small molecule, microRNA-101, that can block autophagy in cancer cells, making them more sensitive to treatment with the anti-hormone Tamoxifen. This breakthrough has significant clinical relevance for treating breast cancer.
Professor Hilton's receipt of the award recognises his research into how cytokines signal between cells, including the discovery of many molecules involved in this process. He has made significant contributions to our understanding of cytokine biology and its applications in cancer, infectious diseases, and autoimmune conditions.
Healthcare access in Greece declined during the financial crisis, with long waiting times and supply-side problems contributing to reduced doctor consultations. This led to increased hospital admissions, suicides, and other alarming indicators such as rising HIV infections and heroin use.
Researchers have discovered gamma rays with unprecedented energies from the Crab Pulsar in the Crab Nebula, contradicting existing theories. The findings suggest a different mechanism for producing these high-energy particles, which could be detected by the VERITAS observatory.
A University of Wisconsin-Madison study suggests that short-term sleep restriction in adolescent mice prevented balanced growth and depletion of brain synapses, which may have lasting consequences for the wiring of the brain. The study's findings could be relevant to mental illnesses like schizophrenia that often start during adolescence.
Researchers at the University of Illinois at Chicago have created a biosensor to measure membrane lipid levels, which can act as switches turning on or off protein-protein interactions. This technique allows for real-time quantification and monitoring of lipid molecules, potentially leading to new pathways for disease treatment.
Researchers discovered three new DNA faults linked to melanoma, which are not related to hair, skin, or eye color. The genes, MX2, ATM, and CASP8, increase the risk of developing melanoma by 30 percent, particularly in people with two copies of these gene faults.
A UA-led team of researchers discovered a new edge in overcoming resistance to certain pests by modifying the structure of crop-protecting proteins called Bt toxins. The modified toxins were found to be effective against some resistant strains, but not always working as expected and requiring further testing.
Over the past decade, antiretroviral therapy has effectively managed HIV in adults with virological failure to all three original drug classes. Since 2000, nearly one in five patients achieved undetectable viral loads after treatment failure, increasing to nearly three in five by 2009.
A recent study published in Nature Cell Biology has discovered that bookmarking genes before cell division accelerates their reactivation afterwards. By analyzing the kinetics of gene activation, researchers found that a histone molecule undergoes chemical modification and is preserved during mitosis, allowing for rapid reactivation.
Research shows that optimistic individuals tend to filter out negative information, updating their estimates only when the new data is better than expected. This faulty frontal lobe function can lead to unrealistic predictions and a lack of caution, with potential downsides for mental health and decision-making.
