The findings emphasize the growing role of imaging technology in individualized cancer treatments.
A study by Dahlia Remler and Sherry Glied found that Health Savings Accounts (HSAs) may not reduce healthcare spending for the lowest and biggest spenders. In fact, cost-sharing increases for mid-range spenders, while tax subsidies benefit higher-income individuals disproportionately.
Prolonged immobility in older adults can lead to functional decline within 48 hours. Simple policy changes can prevent complex problems and improve patient outcomes.
The European Molecular Biology Laboratory examines the social, economic, and ethical impact of dual-use research on society. Researchers discuss potential options to reduce the misuse of proteomics and explore the consequences of biological and medical knowledge on citizens' privacy.
A recent study published in Nature reveals that neural crest cell formation occurs earlier than previously thought, independent of tissue interactions. This breakthrough could lead to a better understanding of developmental disorders such as cleft palate and heart valve malformations.
The DOE JGI has selected over 40 projects to sequence the genomes of switchgrass, cassava, and other organisms for biofuel production. The goal is to improve biomass productivity and feedstock quality for a more sustainable energy future.
Florida State University has been awarded a $6-million grant from the federal government to conduct research on learning disabilities and dyslexia in children. The center will enable FSU researchers to conduct behavioral and genetic studies involving thousands of Florida children with dyslexia.
Researchers used a supercomputer to calculate interactions among neutrons and protons from quark and gluon properties, providing insight into how nuclear forces emerge. This breakthrough paves the way for understanding how finely tuned the universe is and could reveal essential information about carbon-based life.
A survey by ARVO found that the major factor limiting the use of human eye tissue is a lack of availability meeting stringent criteria. Researchers are exploring ways to manage the shortage, including working closely with eye banks and clarifying experimental needs.
A new University of Florida study suggests that large dinosaurs, such as Sauroposeidon proteles, had body temperatures close to 48 degrees Celsius, comparable to modern-day birds and mammals. This discovery challenges the long-held assumption that dinosaurs were cold-blooded reptiles.
ARP/wARP software has been upgraded to handle lower-resolution data, enabling researchers to study complex problems in cancer, cardiovascular, and neurodegenerative diseases. The new grant will allow scientists to focus on structure analysis rather than building models, potentially leading to revolutionary therapeutic strategies.
Scientists at the University of Alberta developed a unique coating process to make the sharpest tip known, opening doors to new possibilities in electron microscopy and nanotechnology. The sharp tips can withstand extreme temperatures and enable finer resolution in electron microscopes.
Research using PET imaging shows a significant correlation between initial dopamine receptor levels and self-administered cocaine use rates. Lower receptor levels are associated with higher cocaine use rates, suggesting that increasing D2 receptors may alleviate addiction.
A study published in JAMA found that removing ovaries can significantly reduce the risk of ovarian, fallopian tube, and peritoneal cancers in women with BRCA1 or BRCA2 gene mutations. The procedure offers an 80% reduction in cancer risk, making it a recommended preventive measure for these high-risk individuals.
Researchers from NDRI found that offering innovative vocational programs with active outreach and support resulted in higher participation among unemployed methadone patients. Most 'needy' patients became more engaged when offered vocational counseling, leading to reduced relapse rates.
Johns Hopkins researchers show that psilocybin can induce mystical/spiritual experiences descriptively identical to those reported for centuries. Subjects who underwent the experience reported positive changes in behavior and attitude, lasting several months. The study's results have significant implications for our understanding of hu...
A 20-year study found that type 2 diabetes is associated with primary open angle glaucoma (POAG), a leading cause of blindness. Researchers observed over 76,000 women and found a positive association between type 2 diabetes and POAG, regardless of duration.
A study published in JAMA found that women who smoke are more susceptible to lung cancer than men, with a higher rate of diagnosis. However, women tend to survive longer after diagnosis than men, with better survival rates for all major histological types of lung cancer.
Connexions will provide tools to turn passive study materials into active learning resources in Vietnam. The system combines cutting-edge software with an innovative legal framework, encouraging individual self-publishing and collaboration among authors, instructors, and students worldwide.
A recent study published in JAMA Network found that older adults who engage in more daily physical activity have a lower risk of death. The researchers measured energy expenditure over a two-week period using doubly labeled water and found that higher levels of activity were associated with a 69% lower risk of death.
A recent survey of nearly 2,000 Bengali youths found that parental forgiveness and reconciliation promote adaptive shame management and reduce bullying behavior. The study suggests holding bullies accountable while re-integrating them into social groups where they feel loved.
A $2.8M NIH grant enables researchers to explore a harmless bacteriophage, nicknamed the 'Bronx Bomber,' that disrupts the biofilm coating of Mycobacterium smegmatis, potentially leading to more effective TB treatments.
A new study uses a 3D model to reveal the secrets of metastasis in human prostate tumor cells. Cells move slower and need to chop or squeeze through fibers to progress. The research provides insights into why two-dimensional assays for metastasis-inhibiting drugs are not effective.
Scientists at Argonne National Laboratory have discovered a surprising new understanding of water quality, revealing that ions can co-exist as both outer-sphere and inner-sphere species. This breakthrough could lead to better control of water quality and a deeper understanding of various processes at solid-liquid interfaces.
A recent study published in JAMA Network found that weight gain since early adulthood is associated with an increased risk of breast cancer in postmenopausal women. Women who gained 55 pounds or more after age 18 were at a 45% increased risk, while those who lost 22 pounds or more and maintained their weight had a 57% lower risk.
A groundbreaking study found that nearly all children with chronic otitis media have resistant biofilm bacteria in their middle ears, rendering antibiotics ineffective. This discovery sheds new light on the treatment of chronic ear infections and suggests alternative approaches such as probiotics.
