A team of Princeton University scientists tested Albert Einstein's theory of general relativity at cosmic scales, concluding it works as well in vast distances as in local regions. They analyzed over 70,000 galaxies and demonstrated that the universe follows Einstein's rules up to 3.5 billion light years from Earth.
A new study published in The Journal of Physiology found that short-term high-intensity interval training (HIT) can be an effective alternative to traditional long-term exercise. By incorporating brief bursts of intense exercise, individuals can improve muscle function and burn fat without needing extensive exercise time.
A team of researchers has analyzed over 70,000 galaxies to test two modified gravity theories that aim to explain dark matter's effects on the universe. The study found that one theory, TeVeS, can be excluded due to large uncertainty in measurements, while another theory, f(R), still allows for exclusion of dark energy with current data.
Keystone Symposia has received a $1.37 million grant from the NIH to enhance diversity initiatives for underrepresented minority scientists. The grant will support programs such as outreach, scholarships, and a Fellows Program that provides mentoring and networking opportunities.
A study published in Oncogene reveals that microtentacles, extensions of plasma membrane on breast cancer cells, play a key role in metastasis. Targeting these microtentacles may provide a new way to prevent or slow the growth of secondary cancers.
Researchers at Washington University in St. Louis have developed gold nanocages that selectively accumulate in tumors and convert laser light to heat, killing malignant cells. The treatment avoids warm surrounding tissue, making it a promising approach for cancer therapy.
Tropical Storm 90Q, the second known cyclone in South Atlantic Ocean history, is located over 1,350 miles east of Buenos Aires. The storm is moving quickly south-southeast and expected to be merged with a cold front by weekend.
K-State professor Simon Ou has received a National Science Foundation CAREER Award to develop automated reasoning for cybersecurity. His project aims to improve enterprise network security and critical infrastructure protection by providing a theoretical framework for reasoning under uncertainty.
A Rice University team re-examined Gustav Mie's century-old equations for electromagnetic wave interaction with spherical metal particles. The researchers found that average properties matched the predictions, but individual particles deviated significantly due to shape and orientation variations on the substrate.
Researchers evaluated outcomes of 218 patients who participated in non-recommended activities after TKA surgery and found no significant differences in implant durability or radiological results. The study showed that such activities might actually improve clinical scores, contradicting industry recommendations.
Tropical cyclone 20P has strengthened into a tropical storm in the South Pacific Ocean, with a large cluster of high, cold thunderstorms around its center. The storm is moving west at 7 mph and has maximum sustained winds near 52 mph.
The new guidebook covers geologic terrain from eastern Pennsylvania to northeastern West Virginia, highlighting diverse landscapes and tectonic evolution. It also offers opportunities for readers to explore the complex geology of the southeastern and northeastern United States.
A new study in Organization Science journal suggests that securities analysts' reluctance to recommend investment in new technologies can harm veteran companies. The researchers found that analysts prefer strategies that extend existing technologies over those that directly respond to new technology, with negative implications for mana...
The American Society for Radiation Oncology (ASTRO) has awarded travel grants to 17 radiation oncology professionals to attend Advocacy Day. The grants aim to support the financial constraints faced by residents and nurses in advocating for their patients' interests.
The American Thoracic Society has released new guidelines for CCHS, citing crucial discoveries linking the condition to mutations in the PHOX2B gene. Affected individuals require fastidious medical supervision to attain optimal quality of life, and early identification and intervention are critical.
The World Federation of Chinese Medicine Societies has urged its members not to use tiger bone or other endangered wildlife parts, citing lack of medicinal benefits. The call aims to support tiger conservation and reduce trade in big cat products.
A phylogenetic analysis of Mexican cave scorpions reveals that specialized adaptations can be reversed through independent evolution. Three surface-living species evolved from cave-dwelling ancestors, highlighting the flexibility of scorpion biology.
Tropical Storm Tomas is expected to intensify over the weekend, bringing gusty winds, ocean swells, and heavy rainfall to residents of Nadi, Fiji. The storm has strengthened by 23 mph since March 11, with forecasters predicting it will weaken due to increasing wind shear from Monday or Tuesday.
A study found that the average age of patients having total knee replacements decreased by two years between 1990-1994 and 2002-2006. The percentage of minorities also increased during this time period. Additionally, hospital stays decreased from 8.4 days to 3.9 days.
Researchers found that Notch protein represses the pathway in cells emitting signals, but activates it in neighboring cells. This discovery may lead to more effective therapies against cancers such as leukemia and breast cancer.
A new NIH-funded clinical trial has found that ethosuximide is the most effective treatment for childhood absence epilepsy, with no intolerable side effects. The study enrolled 453 children and showed that ethosuximide and valproic acid were significantly more effective than lamotrigine in controlling seizures.
A University of Michigan study found that nearly 16.8% of eligible emergency visits from 2000-2006 involved potentially inappropriate medications for patients aged 65 and older. The top five most common PIMs were promethazine, ketorolac, propoxyphene, meperidine, and diphenhydramine.
A Clemson University assistant professor is using a $415,430 NSF CAREER Award to investigate social capital's impact on underrepresented students' decisions to enter engineering fields. The research aims to determine if these students use different mechanisms to access social capital and develop education and career-related goals.
Research discovers changes in muscle cell structure affecting gene expression and actin protein mutations causing muscle damage. The study sheds light on the biochemical pathways leading to nemaline myopathy, a rare inherited muscle-wasting disease.
A large multicenter trial in Japan found that patients with early gastric cancer who received H. pylori antibiotics after surgical resection had a significantly lower risk of developing gastric cancer. Certain strains of H. pylori may carry an increased risk of developing gastric cancer, but more research is needed to fully understand ...
A study by the USDA's Agricultural Research Service found that vitamin D levels are more important than increasing calcium intake for better bone health. The study suggests that correcting low vitamin D levels is key to improving bone mineral density, especially among women with low vitamin D concentrations.
Space physicists from the University of Leicester have identified a significant contributor to Mars' atmospheric escape: pressure from solar wind pulses. The team found that these pulses can drive away particles from Mars' atmosphere, causing a loss of about one third of the material lost into space.
Researchers at McMaster University found that interval training can be an effective and time-efficient way to reduce the risk of Type 2 diabetes. The study involved eight to 12 one-minute bouts of exercise with rest intervals, resulting in a total of 20-25 minutes per session.
