Researchers found that fermented cabbage produces cancer-fighting isothiocyanates, which may prevent the growth of various types of cancer. The fermentation process also creates healthy compounds like lactic acid, making cabbage easier to digest.
Two studies found that reducing air pollution through coal bans and emission controls leads to significant decreases in mortality rates, particularly for respiratory and cardiovascular diseases. Estimated reductions include 116 respiratory deaths and 243 cardiovascular deaths per year.
A study published in Immunity reveals that the MEF protein plays a critical role in the development and function of natural killer cells, which can recognize and kill cancer cells. The findings provide a new target for therapeutic interventions, potentially improving bone marrow transplant strategies.
A new study found that genetic test results for HNPCC may motivate colonoscopy screening among those who test positive, increasing screening rates. The American Association for Cancer Research recommends more targeted training on screening recommendations for underserved communities.
A new theory explains how prion diseases get started and kill neurons by showing that small amounts of misfolded PrP in the cytosol can cause cell death. The research also reveals a mechanism for the conversion of normal PrP to its toxic form, which can then spread and aggregate.
The study found three catastrophic droughts in Africa 8,300, 5,200, and 4,000 years ago, which coincided with the formation of cities and social structures. The ice cores also showed a significant decline in oxygen-18 isotopes, indicating another severe drought event around 5,200 years ago.
UMass geoscientists are part of a team studying the retreat of Kilimanjaro's glaciers, using continuous data from a mountaintop weather station and monitoring the glaciers. The researchers found an 80% decrease in glacier area between 1912 and the end of the 20th century.
A severe shortage of geriatric-trained nurses and healthcare professionals threatens the well-being of older Americans, with only a few percent of RNs certified in geriatrics. The authors call for increased investment in geriatric education and training across all healthcare disciplines.
Scientists have found a way for single-celled organisms like Tetrahymena to protect themselves against harmful invaders by co-opting their attributes. This system, discovered by Martin Gorovsky and Kazufumi Mochizuki, helps regulate the cell's genome and prevent disastrous effects from genetic mutations.
UCSF's Institute for Global Health has been awarded $4.5 million by the CDC to assist in global AIDS programs, focusing on training, technical assistance, and research in resource-constrained countries. The consortium will also establish regional coordinating centers in Brazil, India, and Zimbabwe.
The study found that younger children focus on capturing moments and details, while older kids start to consider aesthetics and formal properties. Children's photography skills improve significantly as they age, reflecting their growing understanding of the relationship between the physical world and the resulting image.
High school chemistry teacher Crowley has been honored with a regional award for her efforts to challenge and inspire students, provide high-quality instruction, and participate in extracurricular activities. She leads her students in research projects, including analyzing omega-3 and omega-6 fatty acids in French fries.
Astronomers have identified a vivid scar in the Centaurus A Galaxy, composed of clusters of young blue stars formed after the galaxy absorbed a smaller satellite galaxy 200 million to 400 million years ago. The discovery suggests absorption of smaller galaxies may contribute to galactic halo formation.
A preliminary study found that the peritoneal fluid of women with early-stage endometriosis reduces ciliary beat frequency by around a quarter compared to fertile controls. This reduction may be linked to impaired ciliary action and tubal transport, which could negatively impact fertility.
Researchers at Cornell University have developed a tiny atomic battery that can run for decades unattended, converting radioactive energy into motion. The device uses nickel-63 isotope and has potential applications in sensors for missiles and medical devices.
A new Center for Health Disparities Solutions will bring together resources from Johns Hopkins and Morgan State University to conduct research, training, and interventions to address health disparities. The center plans to educate participants on conducting research on disparities and establish connections with healthcare advocacy groups.
Researchers used precancerous breast cells from patients with Li-Fraumeni syndrome to test the effectiveness of chemopreventive agents in preventing cancer. Treatment with tamoxifen, a p53-rescue drug, and PPAR-ã agonist showed promise in stopping cancer development, suggesting new potential therapies for high-risk individuals.
The Big Ten university consortium is enhancing its research and training reactors to improve nuclear education and infrastructure. The four universities will share $1.97 million in funding to design the next generation of nuclear research facilities.
Researchers discovered that the Tryptophan cage protein, composed of 20 amino acids, folds into its three-dimensional shape at an unprecedented rate. The protein achieves this in just four-millionths of a second, beating any other protein by about four times.
Researchers discover that the Earth's magnetic field remained stable during a superchron period 95 million years ago, suggesting a single mechanism governs the field. The study also indicates that humanity may face a surprise in the future with possible pole reversals within centuries.
The study found that older men are more likely to have sperm with genetic mutations causing Apert syndrome, which increases the risk of having a child with the disease. The scientists suggest that the number of cell divisions in making sperm plays a role in this link.
Researchers have successfully measured electrical resistance and magnetic properties of lithium under extreme conditions. The discovery reveals multiple transitions in the element's structure, reevaluating its properties.
A randomized, double-blind trial found that magnesium supplementation had no effect on 30-day mortality in patients with acute STEMI. The study's results support current coronary care practice and suggest that routine administration of intravenous magnesium is not indicated.
Researchers have discovered a new way to prevent cell death in the brain, which could lead to treatments for stroke, schizophrenia, and other neurological disorders. By enhancing the interaction between two proteins, they may be able to design medications that target specific brain functions.
Research reveals that people near freeways are exposed to 30 times more ultrafine particles, linked to neurological changes and cardiovascular problems. The study measured particle concentrations near two major freeways in Los Angeles, finding a significant decrease in particle concentration with distance from the freeway.
A recent study reveals that asthma affects over 42,000 US households, with moderate to severe persistent disease prevalent among individuals. Additionally, the research highlights the significant impact of asthma on daily activities, affecting two-thirds of respondents.
Researchers at Ohio State University and MIT found that a specific protein misfolding in an organelle leads to the transmission of transmissible spongiform encephalopathies. The misfolded proteins accumulate in the cytosol, altering cell metabolism and killing neural cells.
Magnussen fostered diversity through outreach programs, including Texas A&M's Women in Science and Engineering (WISE) program, which now supports female faculty and students. She also promotes positive role models and organizes research competitions for young science enthusiasts.
