A new study found that short-term hormone therapy can significantly improve the outlook for men with early-stage prostate cancer. Researchers discovered that testosterone suppression before and during radiotherapy reduced the risk of relapse by up to 44%.
Researchers found that specific versions of the TGFb1 gene are linked to worse lung disease in cystic fibrosis patients. The study's large size and robust design enabled scientists to identify a potential target for improving CF therapy.
A new study has tracked the evolution of the H3N2 influenza virus in New York over five flu seasons, revealing at least three distinct subpopulations of the virus. The research demonstrates the potential for genomics to inform vaccine development and improve public health by understanding the dynamics of flu virus evolution.
Endosomes travel to the nucleus using back-and-forth movement, accumulating at an aster-like layout of microtubules. This symmetrical approach allows for efficient distribution of nutrients and molecular information.
The university will use the grant to enhance its Clinical Scholars Program, which supports young investigators in a three-year educational and training program. The initiative aims to create an environment for career development of young faculty in clinical research.
The NIH has secured contracts with Deltagen Inc. and Lexicon Genetics Incorporated to provide researchers with extensively characterized lines of knockout mice, featuring disrupted genes. This comprehensive resource will greatly accelerate efforts to explore gene functions in health and disease.
Researchers found that ICDs provide value in appropriate patients, but more research is needed to identify high-risk patients who would benefit most from the therapy. The study suggests that ICD use could be more cost-effective with lower implantation costs or extended device lifespan.
Researchers reconstructed the 1918 flu virus using reverse genetics, a technique developed by Mount Sinai School of Medicine researchers. The study reveals that the virus is extremely virulent in mice and grows rapidly in human lung cells.
Astronomers have discovered the first optical afterglow of a short gamma-ray burst, providing evidence for their cosmic explosion hypothesis. The findings suggest that these bursts originate from the merging of compact stars in elliptical galaxies.
Researchers found that human subjects learned different levels of a video game in just 20 minutes, adapting to varying environmental difficulties. The study showed that people can rapidly reshape their learning process to best learn new movements.
Researchers found that fish in ponds increase pollination of St. John's wort due to the decline of dragonfly populations, which then shift their prey to bees and flowers, fostering a mutually beneficial relationship. This study highlights the impact of species interactions on ecosystem dynamics.
Researchers at Max Planck Institute have found that the surface of lime platelets in mother-of-pearl is disordered and wavy, ruling out ordered layers on the organic matrix. This discovery challenges previous understanding of nacre's composition and mechanism, offering new insights into building materials.
The HETE-2 satellite has solved the mystery of short gamma-ray bursts, revealing colliding compact stars as their likely cause. The discovery provides significant findings, including first observations of optical afterglows and secure measurements of distance to a short burst.
The study used repetitive triplet sequences of tones with alternating frequencies to explore how the brain perceives auditory streams. The researchers found that at intermediate frequency separations and speeds, listeners' perceptions shifted from a single stream to two separate streams.
The Center for Engineering Sustainability aims to promote sustainable engineering practices among US engineering programs, providing peer-reviewed materials and workshops. With $1.7M NSF & $350K EPA support, the initiative seeks to encourage engineers to incorporate environmental constraints into projects.
A new book argues that the WTO should prioritize sustainable development and fair trade to contribute to poverty alleviation. Professor Gary Sampson presents policy options that are both ambitious and realistic for governments to adopt.
The new guidelines aim to improve psychiatric evaluation, screening, and treatment for juvenile offenders. They recommend educating clinicians on unique system issues and refer juveniles with mental health or substance abuse disorders for systematic evaluation and treatment.

An international study found that 21% of coronary patients continued to smoke, with younger patients and those with angina less likely to quit. The survey highlights the need for more effective smoking cessation programs, particularly among younger patients and those with lower education levels.
Children with advanced cancer can make informed decisions about their treatment, prioritizing the needs of others. The study found that 95% of participants cited caring for others as a factor in their decision-making, highlighting the importance of relationship-based end-of-life care.
A team of researchers used proteomics to identify multiple blood proteins that adsorb to the surfaces of medical devices, including serum amyloid P. This discovery sheds new light on the biocompatibility of materials and their potential impact on patient health.
Two patients with a rare illness lost ability to perceive their own body, yet could correctly guess weight of boxes lifted by others. They relied on internal simulation to interpret body movements, suggesting our brains simulate others' actions to understand their intentions.
A study found that fish indirectly aid plant reproduction by reducing adult dragonflies, which in turn increase bee and butterfly populations, leading to more plant pollination. The research highlights the unexpected connections among species and how human activities can shape nature.
A team of researchers has identified key genes responsible for the Spanish flu's extreme virulence, which could lead to the development of effective antivirals and vaccines. The study also suggests that certain FDA-approved flu medications may be effective against future strains of the virus.
