Researchers at Temple University have found a simple color-changing oral strip can help detect gum disease more quickly and easily than traditional methods. The strips change color based on levels of microbial sulfur compounds in saliva, providing a comparable screening method.
Recent observations from the USArray transportable array and EarthScope instruments have shed new light on seismic wave propagation and the evolution of the Yellowstone hotspot. The analysis suggests a common mantle source for the region's unique topographic features, providing valuable insights into geological processes.
Researchers at MIT have developed a novel method for creating exceptionally fine lines on microchips, overcoming fundamental limits in light-based technologies. The technique uses interference patterns to produce transparent lines interspersed with opaque material.
Patients given an omega-3 enriched supplement maintained all aspects of their body composition after surgery, while those without it suffered clinically severe weight loss. The study suggests that omega-3 fatty acids may reduce the risk of post-surgical complications by suppressing inflammation.
New research suggests climate change will impact ozone recovery rates due to changes in atmospheric circulation. Greenhouse gases alter the Brewer-Dobson circulation pattern, influencing ozone distribution and leading to uneven ozone layer recovery.
Researchers at UT Southwestern Medical Center found that the protein Thymosin beta-4 initiates migration of heart cells and blood vessel growth after a heart attack, encouraging new growth and repair of damaged heart cells. The molecule affects developmental gene expression as early as 24 hours after systemic injection.
A study by Brown University researchers found that nursing homes serving primarily Hispanic residents provided poorer quality care, including higher rates of bed sores. The study looked at data from California, New Mexico, Texas, Arizona, and Colorado and found disparities in care related to racial segregation.
Dr. Neal F. Lane, a prominent physicist and former U.S. presidential science advisor, has been awarded the AIP's Karl T. Compton Medal for his outstanding contributions to physics through exceptional statesmanship. He is recognized for his advocacy of public understanding of science and technology, as well as his championship of scient...
A team of astronomers has found a sample of massive galaxies with properties suggesting they may have formed recently, running counter to widely-held beliefs. The discovery challenges our understanding of galaxy formation and evolution, offering new opportunities for research into the origin and early history of galaxies.
Researchers studied ICU patients with acute lung injury (ALI) and found that those with greater organ failure and higher benzodiazepine doses were more likely to experience depression after discharge. The study suggests that certain aspects of critical illness and ICU care may contribute to depression.
A study by Kansas State University researchers found that people drive at speeds based on their perceptions and existing conditions, rather than adhering to posted speed limits on gravel roads. The study also revealed no safety benefits from posting speed limit signs or reducing the speed limit.
The ALCF's powerful installation of NVIDIA Quadro Plex S4 external GPUs enables scientists to visualize and analyze vast amounts of data from high-performance calculations. This allows for dramatic reductions in time needed to create complex visualizations, boosting their quality.
A three-year NSF grant will help improve protein production in crops through research on Arabidopsis gene conversion. The study aims to understand how plants control protein synthesis and identify key steps and factors involved.
A recent study by Mount Sinai faculty suggests that a gene associated with type-2 diabetes decreases in Alzheimer's disease dementia cases. The research found that promoting PGC-1 content in brain cells attenuates hyperglycemic-mediated β-amyloid production, linking type-2 diabetic metabolic defects to increasing dementia.
Researchers developed a test to quickly assess the effectiveness of Alzheimer's drugs in reducing amyloid beta production, which builds brain plaques. The test, SILK, was used to study LY450139, an Eli Lilly drug candidate, and showed a dose-dependent drop in A-beta production.
A team of scientists has sequenced the genomes of two tiny marine algae, revealing unexpected genes with functions similar to those found in land plants and bacteria. The findings highlight the complexity of these organisms and their potential role in shaping marine food webs and carbon cycling.
Researchers found that teaching kids the underlying structure of math problems enhances their understanding and ability to solve them. This approach, known as conceptual instruction, enables students to explain the problem and its solutions on their own.
Researchers found that comparing different solution methods enhances students' understanding of math concepts and improves their flexibility in solving equations. This approach is more effective than comparing problems solved using the same method.
Scientists from the University of Miami Rosenstiel School and University of Oxford have analyzed data to identify details of the major plate boundary event that destroyed 90% of Pisco, Peru. The study reveals maximum intensity and damage occur few tens of kilometers south of the epicenter.
A CSHL-led team has identified a critical role for the protein EYA in setting the machinery for DNA repair, allowing cells to either fix broken DNA or die. The discovery sheds light on how cells make decisions when faced with catastrophic DNA damage.
Researchers have determined the molecular structure of a plant photolyase protein similar to two cryptochrome proteins controlling the human clock. The study reveals key differences between human and plant cryptochromes, shedding light on the complexities of the human sleep/wake cycle.
