A new study published in New England Journal of Medicine found that age alone should not determine whether an older patient is offered chemotherapy after surgery for treatment of stage II and III colon cancer. The study showed a significant reduction in death risk and improved survival rates among patients over 70 with the disease.
Research suggests that leptin, a hormone involved in weight regulation, may be more closely tied to mental factors than previously thought. Studies have found that alterations in brain structure and function may play a key role in leptin-related obesity.
The National Science Foundation (NSF) has announced eight institutional transformation awards to enhance the participation of women in science, engineering, and academia. The awards aim to improve diversity in STEM fields by creating models that can be replicated nationwide.
A bacterial peptide has been identified as a key regulator of host responses to infection. This discovery opens up new avenues for the development of therapies targeting this process.
Researchers have discovered a novel calcium-selective ion channel gene, CatSper, that controls the flow of calcium into the tails of spermatozoa. This finding could lead to the development of a new type of contraceptive that targets this protein, potentially offering fewer side effects than current hormone-based contraceptives.
A new study analyzes three model plans and finds that competitive pricing may reduce plan uncertainty but is unlikely to raise enrollment in the M+C sector. Total government spending on Medicare could be reduced by increasing beneficiary premiums, but geographic inequities in benefits are a concern.
Research investigates how tumor suppressor genes are methylated during development, affecting cancer risk. The study reveals complex interactions between epigenetic regulation and cellular differentiation.
Researchers studying Drosophila flies have identified key molecules regulating epidermal growth factor receptor signalling, which is crucial for developmental processes and cell growth. The study's findings have implications for understanding human diseases like cancer, with potential applications in medical advances.
The center will provide cutting-edge instrumentation and theoretical expertise to researchers worldwide, focusing on biochemistry and molecular biology. Researchers will utilize state-of-the-art ESR spectrometers to study dynamic molecular processes and develop new methods for measuring distances in biomolecules.
A combination of edible oils from fenugreek, cumin, pumpkin seed, and oregano improved glucose metabolism in diabetic rats, reducing the need for insulin. The study suggests that these natural products may be effective in treating Type II diabetes and high blood pressure.
Patricia B. Smith has developed a hydrogen-based plasma process that effectively removes residues from pure copper interconnected layers, enabling the manufacture of state-of-the-art semiconductor devices. This breakthrough technology will also be used for future generations of smaller device technologies.
Researchers at Cornell University found that about one-third of baby boomers plan to continue working after retirement, prioritizing travel, volunteering, and education. The study suggests a shift in how baby boomers view retirement, with many viewing it as a transition to a more flexible work-life balance.
Researchers found oregano oil to inhibit staphylococcus bacterial growth as effectively as standard antibiotics. A study using mice also showed that oregano oil and carvacrol had promising results against the bacteria.
Dr. K. Barry Sharpless' discovery of chiral catalysts has enabled the production of useful molecules, including therapeutics that improve human health and lives. His work has streamlined the creation of important chemicals, including antibiotics and heart medicines.
A Johns Hopkins University team is developing a speech recognition system to help historians sift through Holocaust survivor interviews in languages other than English. The system aims to improve access to the archive's vast collection of video interviews.
A study found that invasive Argentine ants eliminate native ant species, affecting seed burial and plant regeneration in fynbos ecosystems. This disruption can have cascading effects on the entire community, highlighting the threat of invasive species.
Researchers at the University of Michigan found that generic drugs have stabilized at about 40% of prescriptions, despite growing market share. The team suggests therapeutic interchange as a viable solution to balance cost-cutting with effective medication.
The establishment of these centers brings together unique research expertise to perfect islet cell isolation and availability techniques. The centers aim to improve cellular viability, function, and shipping procedures for patients with type 1 diabetes.
The European Molecular Biology Organization (EMBO) has awarded Matthew Freeman the 2001 golden medal for his significant contributions to molecular biology. The prestigious award recognizes Freeman's groundbreaking work in this field.
ExxonMobil scientists have developed a novel catalyst and process called SCANfiningTM, effective in reducing cracked naphtha sulfur levels up to 99%. The new process overcomes challenges of traditional methods, which are either too expensive or result in lost octane required for modern engines.
Scientists have found that gradual changes in ecosystems can lead to catastrophic collapse, as even small disturbances can trigger irreversible shifts. This is evident in various ecosystems around the world, including coral reefs and forests.
