A new study by Whitehead researchers found that reduced DNA methylation may be responsible for decreased genomic stability and increased mutation rates in cancer cells. This could lead to a better understanding of the molecular origins of cancer.
A study by OHSU found that patients who completed the bright pink POLST form had high levels of comfort care and low rates of aggressive life-extending treatment. The form, which enables patients to state wishes on specific treatments, was designed to record patients' wishes in the present, not just future healthcare.
Researchers propose instrument to measure high-energy gamma rays from blazars, pulsars, and bursts, offering improved tracking capabilities and higher energy detection limits. The scintillating fiber detector system will act as both a tracker and calorimeter, providing a wide-angle view of the sky with unprecedented precision.
The UCSF Center for AIDS Research has been awarded a major grant from the National Institutes of Health to support ongoing work in basic, clinical, and behavioral science areas of HIV/AIDS. The grant will focus on developing new treatment approaches, understanding HIV transmission, and improving therapy effectiveness.
Researchers have discovered a new method to deliver drugs directly to the brain using nose drops, potentially treating Alzheimer's disease, Parkinson's disease, and multiple sclerosis. The treatment uses nerve growth factor and has shown promising results in animal studies.
Researcher Joy Bergelson finds that genetically engineered plants can outcross with wild relatives at a higher rate than previously thought, potentially leading to the creation of super-weeds. This could lead to increased pesticide use and crop competition for water and nutrients.
Golfers can expect to hit longer shots and experience a softer yet solid feel with the new Liquidmetal alloy, absorbing less energy than conventional materials. This high-performance material is also attractive for replacing traditional metals in sporting goods and aerospace products.
A new process called Continuous Rotary Extrusion (CRE) can produce high-quality copper from scrap electrical cable at a lower cost and with minimal environmental impact. The recycling centers can be based in compact light industry plants, reducing staff requirements and operating costs.
Physicists at Stanford University developed a new optical detector capable of measuring individual photons' energy, arrival time, and location throughout the spectrum. This breakthrough has potential applications in dark matter detection and improved astronomical observations.
A study found that women with longstanding hypertension are more likely to develop preeclampsia if they have a history of high blood pressure and protein in the urine early in pregnancy. Women who developed preeclampsia were also more likely to experience complications such as premature birth and low birth weight.
A team of researchers has developed software called Crowds that allows internet users to become anonymous members of a pool of surfers, masking their IP addresses and making it difficult for websites to track their activities. The software routes requests through the crowd, increasing anonymity and reducing profiling attempts.
The Whitaker Foundation has awarded over $7.5 million to biomedical researchers at 29 universities to tackle medical problems and improve human health. The grants support innovative research in areas like regenerative medicine, biomechanics, and tissue engineering.
Dahl's award-winning ion optics simulation program, SIMION, has been instrumental in designing instruments for the Cassini mission to Saturn. On Earth, SIMION is used to analyze environmental contaminants, decode DNA, and uncover illegal drugs in urinalysis samples.
Researchers successfully engineered a hybrid enzyme with improved substrate specificity, demonstrating the potential of recombining subdomains to generate novel functions. The study presents a method for generating hybrid genes by combining subdomain segments from diverse proteins.
A new report recommends guidelines for governments to evaluate proposals for public investment in freight facility projects, focusing on economic viability and benefits such as reduced pollution and job creation. The report also examines government policies beyond infrastructure investment that affect freight efficiency.
A new computing technique uses chaotic elements to 'evolve' answers, offering an alternative to traditional digital computers. The system has demonstrated handling various operations, including addition, multiplication, and Boolean logic.
