Research suggests that taking dietary supplements of L-arginine and antioxidants like vitamins C and E may lower the risk of atherosclerosis and heart disease. The treatment reduced inflammation and increased production of eNOS, a molecule that prevents blood clots.
The Kavli Institute will bring together top minds in particle astrophysics and cosmology to tackle fundamental questions about the universe. The institute will focus on areas like dark matter, black holes, and hidden space-time dimensions.
A new study by Brigham Young University researchers found that walking stick species re-evolved wings after losing them 50 million years earlier. The discovery raises questions about the basics of evolutionary theory and suggests that complexity can be maintained over tens of millions of years.
A NASA study found that lightning strikes in multiple locations, with 35% of recorded flashes striking the ground in two or more places. On average, each cloud-to-ground flash struck the ground in 1.45 separate places, increasing the risk of being struck by 45%.
A UMass study suggests that greenhouse gases were the primary driver behind the rapid formation of Antarctica's ice sheet, contradicting a long-held theory on plate tectonics. The researchers used computer simulations to recreate the world 34 million years ago and found that a drop in carbon dioxide levels triggered the glaciation.
Researchers gather data from an unusual storm over the Amazon rainforest to analyze the storm's inner workings, revealing a two-phase process where both precipitation forms at lower altitudes and higher in the atmosphere. The study provides new insight into storm intensity and hazards, which should be avoided by aircraft.
Scientists at North Carolina State University developed a remote sensing technique to accurately time nitrogen fertilizer applications in wheat, resulting in an 86% success rate across various environmental conditions. This technology allows growers to make informed decisions that balance profitability and environmental stewardship.
Researchers studying the common Australian gecko Christinus marmoratus have found a protein growth factor that contributes to its ability to quickly regenerate its tail after losing it. This discovery is encouraging for treating human lymphoedema, but more research is needed.
Researchers found that herpes viruses use a viral protein called mK3 to hide from the immune system by marking MHC class 1 molecules as waste. This study provides insights into basic cellular processes and offers novel strategies for understanding viral infections.
A recent study by Johns Hopkins Medicine found that medical devices used in procedures like bronchoalveolar lavage can pose a risk of contamination, leading to infections and even fatalities. The study suggests implementing federal standards for recall notices sent to physicians who use the devices.
China's blood banking system is fragmenting due to rural-urban differences and has a scarcity of volunteer donors, leading to paid donations and illegal activities. Improvements are needed to adopt a volunteer-donor-only system, increasing education and training for those involved in blood collection and transfusion.
A Stanford study found a significant link between depression and chronic pain, suggesting that pain may guide doctors to effective treatments for depressed patients. The research also indicates that continuous pain increases the likelihood of major depressive disorder diagnosis.
Researchers create a new, cost-effective way to produce human therapeutic proteins using algae. They can now make large quantities of antibodies and other proteins much cheaper than traditional methods.
Research found that people with a specific iron overload gene mutation are at higher risk of developing colon cancer, especially with increasing age and iron intake. The study analyzed DNA samples from over 1,300 adults and found a significant association between HFE gene mutations and an increased risk of colon cancer.
A study analyzing data from 115,000 women found that smoking rates among pregnant women rose during the study period, but not before or after. The number of quitters increased by 9 percentage points, while 60% resumed smoking within six months post-delivery.
Researchers have identified about 400 genes in Caenorhabditis elegans that control fat storage, including many with human counterparts. These genes may hold the key to developing new therapies for obesity and its associated diseases.
Researchers found that the absence of the SAP gene impairs the immune system's ability to recognize and react to infection, leading to impaired long-term antibody responses. The study has implications for vaccine development and may offer therapeutic benefits in treating X-linked lymphoproliferative disease.
A recent study by the American Association for Cancer Research found that patients with advanced melanoma expressing higher levels of melanoma-associated antigens (MAAs) experienced significantly improved survival outcomes. The study suggests that these tumors may be more responsive to immunotherapy, such as vaccines against melanoma.
Researchers will develop an attosecond laser system to capture electrons in motion, shedding light on atomic behavior and molecular interactions. The system's pulses will last 200 attoseconds, allowing for the first time to measure and probe dynamic processes at the atomic scale.
A study by Purdue University scientists found that dogs on fatty diets exhibited reduced growth, bone formation, and immune function. The research suggests that oxidized fats in the diet can contribute to aging and disease development in humans, particularly children during critical stages of growth.
Researchers at Northwestern University are using genome-wide mutagenesis to identify gene mutations that cause sex reversal in mice. The study aims to understand the function of mammalian genes and their role in gonad development, as well as infertility in humans.
