Two studies found obesity increases risk of aggressive prostate cancer and cancer recurrence in African-American men. Obesity is associated with higher Gleason scores and elevated PSA levels, suggesting a link between excess body fat and tumor growth.
Scientists at Scripps Research Institute discover a compound, reversine, that can convert muscle cells into precursor cells, which can be converted to other cell types. This breakthrough has the potential to revolutionize stem cell research and make it more practical for medical applications.
A population-based study found that infants would benefit most from in-hospital palliative care, while older children with long-term illnesses require community-based and at-home services. Effective end-of-life care for all children needs simultaneous delivery of different modes of care.
A team of scientists has identified a cluster of 88 genes that may act as molecular markers for the developmental potential of different stem cell types and stages. These findings are consistent with previous research on cellular development and plasticity, and shed light on the molecular pathways guiding development.
Gerbrand Izaks and Rudi Westendorp propose a model where diseases are caused by cumulative risk factors, making every age-related change a potential symptom of an illness. This framework encourages doctors to reassess older patients' body functions, comparing results to 'normal values' from healthy young adults.
The new network will provide access to leading-edge fabrication and characterization tools, enable educational outreach to K-12 students, and examine the societal and ethical implications of nanotechnology. NSF funding is expected to be $70-million or higher for five years.
Researchers at Texas A&M University have successfully cloned a white-tailed deer named Dewey, believed to be the first of its kind. The breakthrough achieved through fibroblast cell isolation, culture, freezing, and nuclear transfer may provide valuable tools for conserving endangered deer species.
Researchers solved the structure of aquaporin Z, a water channel found in Escherichia coli that conducts only water at high rates. The protein's unique architecture and strategically positioned amino acid residues restrict the flow of larger molecules, allowing it to maintain osmotic equilibrium.
The National Science Board has approved a $70 million award for the National Nanotechnology Infrastructure Network (NNIN), which will create the world's largest and most comprehensive nanotechnology laboratory. The NNIN, led by Cornell University, will provide access to leading-edge tools and instruments, and contribute to developing a...
The PERs will allow museum visitors to search for organo-fluorescent evidence of life in a Martian terrain, mimicking the role of NASA's Mars Exploration Rovers. The robots are powered by Intel technology and can move at 1.6 inches per second, providing an interactive experience for visitors.
The new Little GLORIAD network increases bandwidth between the US and China to 155 Mbps and enhances research capabilities for scientists worldwide. The network enables joint responses to natural disasters, nuclear materials safeguards, and human genome studies.
New research from NASA scientists suggests emissions of black soot alter the way sunlight reflects off snow, contributing to climate change. The study found that soot in areas with snow and ice may play a significant role in warming the world's climate, especially when it becomes more concentrated on melting surfaces.
Researchers found that brain scans show increased metabolic activity in the temporal cortex, where Alzheimer's disease commonly develops, in adults with Down syndrome. The study suggests that this may be an early indicator of Alzheimer's, potentially allowing for early detection using a common PET scan procedure.
A study led by Rutgers University professor Mohamed Rafi founds a compound called ß-hydroxy-DHP (BHP) in licorice root supplements that can stop the growth of prostate and breast cancer cells. This could provide new hope for more effective therapies against these leading cancers.
Researchers are investigating the role of broccoli-derived chemicals in preventing prostate cancer. The study aims to better understand how these substances inhibit prostate cancer growth and identify potential biomarkers for future intervention trials.
A University of Wisconsin-Madison team has developed a stem cell model that mimics placenta formation during the earliest stages of human development, offering new insights into pregnancy and fetal health. The research could lead to better understanding of diseases like preeclampsia, which affects millions of women and infants worldwide.
A US CDC study found that 10% of vaccine doses administered to children in 2002 were invalid, resulting from premature vaccination. Invalid doses need to be repeated to ensure adequate protection against disease.
Researchers will showcase latest experiments searching for signatures of quark-gluon plasma, a state of matter thought to have existed at the universe's dawn. Controversial observations hint at the possibility of detecting color glass condensate, a previously theorized state within gold ions.
Dr. Squyres and over 40 team members will undergo a sleep study to adapt to Mars' 24-hour day/night cycle during the two-rover mission. The team will work six-sol weeks with varying weekend lengths, aiming to mitigate 'Martian jet lag'.
A recent study using MRI has found significant volume loss in the hippocampus, a key role player in memory functions, among patients with Korsakoff's syndrome and Alzheimer's disease. The study suggests that awareness of these clinical and radiological similarities can aid in early detection of each disorder.
Recent studies demonstrate the accuracy of epilepsy diagnosis by doctors (96%), shedding light on dementia risk factors among adults with Down syndrome. Additionally, gabapentin shows significant effectiveness in treating chronic daily headaches, according to a study by The Australian Gabapentin Chronic Daily Headache Group.
