Men with prostate cancer are 10% less likely to be working six months after diagnosis compared to those without the disease. However, approximately two-thirds of patients continue to work due to fear of losing health insurance coverage, often at reduced hours and with decreased productivity.
A large-scale randomized trial found that low-dose aspirin had no effect on reducing the risk of total cancer, breast cancer, or colorectal cancer in healthy women. The study also suggested a possible trend toward reduced lung cancer risk, but this finding was not statistically significant.
The Genetics and Public Policy Center at Johns Hopkins University will launch a new genetic-testing initiative to build consensus on the safe and accurate use of genetic testing. The two-year $3 million grant aims to improve our understanding of genetic tests and their impact on public health.
Researchers found that adding noise to weak vibrations increased the ability of participants to detect the frequency of the original signal. This effect could be useful in designing prosthetics for the elderly to prevent painful falls and improve balance control.
A recent study published in Pediatrics found that parked cars can heat up by an average of 40 degrees F within an hour, regardless of ambient temperature. This rapid heating can be fatal if left unattended, highlighting the importance of taking children with you when parking.
The Protein Structure Initiative will accelerate structure determination of thousands of proteins, enabling predictions of protein functions and discovery of new drug targets. Rutgers' NESG is a key member of the PSI network, leveraging its expertise in structural biology to advance biomedical research.
A new study found long-duration regular use of aspirin or NSAIDs may lower prostate cancer risk by 18%. Gene variants associated with melanoma risk were also identified in a Mediterranean population study, while another study found no link between gene mutations and response to bevacizumab
Scientists have devised a method to more effectively dampen vertical instabilities in tokamak fusion reactors, allowing for improved control of electrical currents and magnetic fields. This development aims to increase the efficiency of fusion reactions and is an important step towards building the next-generation fusion reactor by 2015.
Researchers have successfully synthesized ammonia from nitrogen using a simple compound of iron and hydrogen in solution, marking a significant step toward achieving one of chemistry's coveted goals. This breakthrough could lead to more efficient and sustainable production of ammonia, a vital fertilizer for global food supply.
