The research, led by Professor Diane McKnight, sheds light on the resilience of microorganisms in polar ecosystems.
A Johns Hopkins University study reveals the brain's subconscious process of organizing images into a 'whole' even when focusing on only one part. The research, based on nerve cell recordings in macaque monkeys, suggests that the brain continuously organizes scenes, even when attending to small parts.
Researchers at the Friedman School of Nutrition Science and Policy at Tufts University have found that long-term vitamin E supplementation may delay cataract development. Additionally, higher intakes of riboflavin and thiamin were associated with reduced cataract progression in women. However, the study's findings on dietary fat intake...
Standard clinical practice guidelines often focus on one disease and exclude coexisting conditions, leaving clinicians without guidance for caring for older patients with multiple chronic diseases. This can lead to polypharmacy, medication errors, and an unsustainable treatment burden.
Researchers found that increased levels of O-GlcNAc, a simple sugar present in high blood sugar circumstances, interfere with the chain of events needed to achieve and maintain erection. This can lead to permanent penile impairment over time.
Scientists aim to develop technology enabling sequence of a single piece of DNA, reducing cost from $10M to $1,000 or less. The goal is to cut the cost of whole-genome sequencing to enable individual genome sequencing in routine medical care.
Scientists have developed a novel structure made from cell components that can assemble into nanotubes with controllable open or closed states. This innovation has the potential to deliver drugs or genes where they would be most effective, using the natural properties of cells similar to skin and bone.
A Penn physician argues that explicit consent is not necessary for HIV testing in critically ill patients, as it can lead to earlier application of life-saving therapies and reduce costs. Alternative methods, such as surrogate consent or court-ordered testing, may be more effective but also pose challenges.
A certain gene variation has been identified as a potential marker for differential response to exercise in older adults. A high level of physical activity was associated with the preservation of physical function, with improved risk benefits seen in those possessing the ID or DD genotypes compared to the II genotype.
Researchers found lower mu-opioid receptor binding in the left insular cortex of women with bulimia, inversely correlated with fasting behavior. This study suggests that medications targeting brain opioid receptors may help treat bulimia, a serious eating disorder marked by destructive patterns of dieting and vomiting.
Researchers have found that the Deccan Traps, a massive lava flow in India, may have released climate-changing gases quickly enough to cause a deadly global climate shift. The team's study suggests that the eruptions could have contributed to the mass extinction event that wiped out the dinosaurs.
German and Malagasy primatologists have discovered two new lemur species, Mirza zaza and Microcebus lehilahytsara, highlighting biodiversity patterns among humans' closest relatives. The discoveries shed light on human origins and evolution, with lemurs being crucial to understanding ancient primate lineages.
Wastewater can be safely reused for irrigation if pretreated, monitored, and using correct crops, say researchers. The study found that viruses in wastewater could linger in soil for up to a month, but were not detected on spinach leaves.
Scientists have discovered microcompartments in bacteria that challenge the long-held assumption of their simplicity, revealing a more complex organization than previously thought. The study provides the first structures of these protein shells and sheds light on their function, sparking potential biotechnology applications.
Researchers found improved patient outcomes in open nephron-sparing surgery (NSS) over time, attributed to increased surgeon experience and perioperative care. Open NSS showed benefits compared to laparoscopic NSS, particularly in complex tumor cases.
Researchers have achieved a cure for haemophilia in dogs using gene transfer strategies. The study identified key problems to overcome before applying this approach in humans, including mode of delivery.
Researchers found that plants grow more and longer secondary roots on the non-self side, suggesting a mechanism based on physiological coordination. This coordination might involve internal pulsing of hormonal or electrical signals that desynchronize when plants are separated.
The study highlights that current clinical practice guidelines (CPGs) often fail to address the complexities of caring for older adults with multiple chronic diseases. The authors recommend that CPGs be revised to include information on comorbidity, patient preferences, and life expectancy to provide more tailored guidance for clinicians.
The Burnham Institute was selected by NIH to receive a $3M grant for exploratory center in hESC research. The center will support pilot projects, core facilities, and training for scientists.
A Mayo Clinic study found that basal cell carcinoma (BCC) tumors are increasing in younger adults, with a significant surge in women over 30. Squamous cell carcinoma (SCC) diagnoses also rose sharply, especially among men and women in their late 30s. Long-term sun exposure and tanning bed use are major contributors to this trend.
A study by Duke University researchers found that pine trees under elevated CO2 levels experienced increased growth in some years, but not consistently. The findings suggest that pine trees may be able to improve water use efficiency, but the results are mixed and more research is needed.
