The University of Minnesota has received a grant to sequence the complete genome of Arthrobacter aurescens, a soil bacterium that can break down environmental pollutants. The project aims to gain tools, such as genes and enzymes, to clean up contaminated environments.
The study found statistically significant increases in mortality rates for A-bomb survivors due to radiation exposure, particularly heart disease, digestive diseases, and respiratory diseases. The cohort of over 86,000 people showed a strong correlation between dose estimates and increased risk of noncancer mortality.
A new combination treatment using arsenic trioxide and radiation has shown promising results in treating glioblastoma, a previously incurable form of brain cancer. The study found that exposing glioblastoma cells to radiation within two hours of receiving a dose of arsenic trioxide amplified the effects of radiation treatment on its own.
A new study by Georgetown University Medical Center researchers found that low-dose CT screenings can accelerate smoking cessation rates by 14%, significantly higher than the national average. This promising finding suggests it's never too late to treat nicotine dependence, and further research may lead to more effective interventions.
A three-year study of 4,122 women from diverse backgrounds found that age, confidence, and social connections play significant roles in exercise behavior. However, unexpected factors such as family size and religious attendance also influenced physical activity levels.
Researchers at Imperial College London have developed a novel flu treatment that can eliminate symptoms by targeting the overactive immune response. The treatment, which works by selectively reducing the response of active T white blood cells, has shown promising results in mice and may offer new hope for pandemic prevention.
A new model of cancer development suggests that Id1 activation may be crucial for tumor growth, contradicting previous research. The study, which used mice exposed to carcinogens, found that tumors developed faster in mice without the Id1 gene.
A six-year study of MRSA in California jails found that two dominant S. aureus clonal groups, ST30:Z and ST8:S, drove the expansion in resistance, gaining multi-drug resistance over time. The study highlights the need to track the spread of individual strains using techniques like PFGE and MLST.
A study tested the ASTRO consensus definition of biochemical failure after combined radiation treatment and hormone therapy, finding it may not accurately predict future disease progression. The study suggests that approximately 20-30% of patients will experience biochemical failure but not continued rises in PSA levels
Brain cancer patients undergoing radiation therapy are at risk of life-threatening infections due to suppressed immune systems. Researchers found that monitoring immune cell counts and administering prophylactic antibiotics can prevent these side effects, with no patient developing pneumonia or other serious infections in the study.
High doses of radiation therapy directed at the prostate significantly impact cancer control in high-risk patients. The major site of treatment failure is the prostate, highlighting the importance of high doses in this group.
Researchers at Cold Spring Harbor Laboratory found that rats can rapidly and accurately discriminate odors with just one sniff. The study, led by Zach Mainen, reveals vital new information about how the human brain processes information and guides behavior, suggesting that smell is a fast sense rather than a slow one.
Researchers identified 25 genes involved in termite caste development, including muscle function and cellulase production. Treatment with juvenile hormone can convert worker termites into soldiers, potentially leading to colony decimation.
A study by USC researchers found that engaging in leisure activities can lower the risk of developing Alzheimer's disease. Among female twin pairs, those who participated frequently in intellectually stimulating activities showed a reduced risk of Alzheimer's. The research controlled for genetics and early life experiences.
Researchers analyzed a large dataset of prostate cancer patients treated with radiation therapy alone. The study examined multiple definitions of biochemical control and found three alternate definitions that offered more accurate predictions of treatment failure.
Researchers at Carnegie Mellon University have received a $2.5M grant to develop software framework for analyzing high-resolution digital images from fluorescence microscopes, enabling the extraction of detailed biological information.
The University of Minnesota is sequencing the Medicago legume genome with a $10.8 million NSF grant, led by Professor Nevin Young. The goal is to understand nitrogen fixation and health-promoting compounds in legumes.
Researchers at Johns Hopkins Kimmel Cancer Center have discovered a gene silencer that blocks cancer cells' ability to repair themselves after chemotherapy and radiation. By reducing the production of targeted repair proteins, the silencer enables cancer cells to become susceptible to therapy.
A recent study published at Fox Chase Cancer Center found that breast cancer patients who did not smoke had significantly better long-term outcomes than those who smoked after undergoing lumpectomy and radiation treatment. The study of over 1,000 patients showed that smoking cessation is crucial in managing breast cancer.
The EMIST project will test defenses against worms, denial-of-service attacks, and routing computer attacks. The experiments will run on the Cyber Defense Technology Experimental Research network (DETER), a new testbed built by UC Berkeley and USC.
Scientists at Rice University develop a new technology that uses disordered nanowires and organic molecules to create functional memory devices. These 'NanoCells' can store information for more than a week without refreshment, far longer than traditional DRAM.
A University of Pittsburgh study found that 22% of seniors over 75 have cognitive disorders, with multiple factors contributing to the condition. The study highlights the importance of good medical care in preventing brain disease and identifying risk factors for cognitive impairment.
Recent studies question the volume-outcome relationship, suggesting that patient characteristics and hospital quality may play a greater role than previously thought. Additionally, topical nerve growth factor shows promise in treating pressure ulcers, with significant healing outcomes reported.
Statistics expert Utts identifies seven common ways statistics are misinterpreted in news reports, including confusion about cause-and-effect relationships. She advises readers to consider possible alternate explanations when interpreting observational studies.
Researchers found that gay and lesbian couples start conflicts with more positivity and less negativity compared to straight couples. They also show more positive emotions during discussions and are less domineering.
