A new technique using scanning tunneling and atomic force microscopes can identify complementary DNA base pairs by measuring the strength of hydrogen bonds. This method could lead to a new DNA sequencing technology that is faster and cheaper than current methods.
Researchers have developed a new yogurt that fights stomach ulcer bacteria with almost vaccine-like effects. The yogurt contains an antibody that reduces bacterial activity, offering a potential alternative to antibiotics for treating gastritis and stomach ulcers.
Increased schooling across sub-Saharan Africa may lower new HIV infections among younger adults, contradicting previous views of education as an AIDS risk factor. Formal education appears to reduce the risk of HIV infections by up to 34 percent in some countries.
A study from the American Chemical Society reports that proteins from garden peas show promise in fighting high blood pressure and chronic kidney disease. The researchers found a 20% drop in blood pressure in rats with polycystic kidney disease when fed small daily doses of pea protein hydrolysate.
Researchers have identified 10 genes linked to changes in QT interval duration, a key factor in sudden cardiac death. The discovery could help identify individuals at risk and aid pharmaceutical companies in developing safer drugs.
Researchers have developed hollow gold nanospheres that target and destroy melanoma cells using near-infrared light, showing eight times more damage to skin tumors than solid gold nanoparticles.
Researchers at UCSC developed hollow gold nanospheres with strong, narrow, and tunable light absorption. These particles can target tumors for photothermal cancer therapy, killing cancer cells with near-infrared light irradiation. The ability to tune optical properties makes them highly versatile for various applications.
Researchers have identified 10 common variants of genes that modify the timing of heart contraction, known as the QT interval. These genetic variations are associated with an increased risk of sudden cardiac death, which claims over a quarter million Americans annually.
Researchers at Washington University School of Medicine have developed a new compound that can detect and visualize immune cell activity, highlighting the misdeeds of the immune system. The compound, called luminol, glows blue when injected into mice with active immune inflammation.
A team of scientists has developed an automated carbohydrate synthesizer, allowing them to build complex carbohydrates in a few hours. This innovation could lead to the creation of new vaccines and treatments for diseases such as malaria and HIV.
A leading cause of plagiarism at the graduate school level is confusion about what constitutes plagiarism, according to an expert. Confusion can be rooted in undergraduate education and may lead to traps. Educators stress the importance of proper citation and context to avoid plagiarism.
Pacific Northwest National Laboratory scientists have developed new materials that improve the power efficiency of blue OLEDs by at least 25 percent. These advancements aim to overcome major research challenges and provide a solution for large-scale applications in rooms and buildings.
Scientists have identified 10 genetic variants linked to an elevated risk of arrhythmias and sudden cardiac death (SCD). These variants influence heart repolarization and raise or lower the risk of cardiac arrhythmias, with a prolonged QT interval increasing the risk up to five-fold.
Researchers at the University of Michigan have developed a new method to detect nitric oxide in exhaled breath, a potential indicator of diseases such as lung cancer and tuberculosis. The technique uses molecular gels that congeal when exposed to nitric oxide and oxygen, allowing for simpler and less subjective detection methods.
