The Merck/AAAS Undergraduate Science Research Program awards grants of $20,000 per year for up to three years to primarily undergraduate institutions. The program aims to enhance undergraduate education through research experiences and encourage students to pursue graduate education in biology and chemistry.
Researchers observed statistically significant amounts of tritium above background in cavitation experiments, suggesting the possibility of nuclear reactions. The findings are based on a collaboration that used high-energy neutrons to create bubbles in liquid, which can result in light emissions and potentially nuclear reactions.
Researchers at Cardiff University have created a cost-effective, realistic surgical trainer using technology typically used in industry. The trainer will be used to perfect key-hole surgery techniques on artificial bodies before being used on real patients.
A nationwide study found long-term exposure to air pollution with high concentrations of tiny particles increases the risk of dying from lung cancer and heart disease. Fine particulate matter levels comparable to second-hand smoke pose significant health risks in polluted cities.
Two new studies published in the Journal of the National Cancer Institute suggest that frequent tomato product consumption may reduce prostate cancer risk. Additionally, researchers found a possible role for the Ras gene in neuroblastoma regression and increased levels of GRP growth factor in head and neck cancers.
A study found that high-volume mammography readers in the US detected fewer cancers than their British counterparts, despite meeting lower annual standards. The research suggests re-engineering US screening programs to improve efficiency and quality without increasing interventions.
A recent study found racial and ethnic disparities in the receipt of cancer treatments, with white patients often receiving more aggressive therapy than minority groups. The study analyzed data from 87 studies and found consistent differences in therapy, including less frequent surgery for lung and colorectal cancers among minorities.
A UCSF study found that radiologists who interpreted a high volume of mammograms were more accurate in detecting cancer. High volume readers had higher sensitivity and accuracy rates compared to low volume readers, suggesting that fewer biopsies are needed to find cancers.
Chronic obstructive pulmonary disease (COPD) is associated with a 3.9% reduction in workforce participation rates, particularly among those with moderate to severe disease. Additionally, sleep-disordered breathing in mildly obese men is linked to glucose intolerance and insulin resistance.
A NASA study reveals strong relationships between El Niño episodes and changes in Antarctic sea ice cover, indicating a connection between the Southern Oscillation and global climate. The findings suggest that El Niño affects regional ice distributions, with notable associations observed in the Amundsen, Bellingshausen, and Weddell Seas.
Researchers at UMass are developing new materials from recycled tires, including a solid rubber object that retains 50-90% of its original strength and elasticity. Another material combines asphalt and recycled tires to create an asphalt alternative that withstands high temperatures and remains flexible in low temperatures.
Researchers at Stanford University used neutron scattering to study the magnetic properties of insulators with random impurities, discovering a novel model magnet. The introduction of nonmagnetic impurities disrupts long-range magnetic order, leading to unprecedented quantum fluctuations.
A management science study finds public research has a significant impact on industrial R&D, with the pharmaceutical industry being a major beneficiary. The study reveals that public research contributes to both innovation and project completion, with materials science and computer science fields having the most widespread impact.
Researchers at Rensselaer Polytechnic Institute used ultrasonic waves to create small cavitation bubbles that could potentially lead to nuclear fusion. The team observed evidence of tritium and sonoluminescence light flashes, which may indicate the fusion of deuterium atoms in the highly compressed bubbles.
A 'volcanic ozone hole' is likely to occur over the Arctic within the next 30 years due to high volcanic activity coinciding with cold winters. This could lead to a significant increase in springtime ozone loss over the Arctic, threatening more populated areas.
A recent study by Children's Hospital of Philadelphia found that children inside compact extended cab pickup trucks are nearly five times more likely to suffer injuries during a crash. The research highlights the unique hazards posed by these vehicles, including side-facing jump seats and insufficient padding.
A recent study found that 51% of pregnant minority women experienced depression, with levels similar between African-American and Hispanic groups. The research highlights the need for healthcare providers to identify and address social support issues in these vulnerable populations.
Researchers at UC Riverside have received a $100,000 grant from the Department of Energy to investigate ways to improve the performance of hydrogen engines. The project aims to reduce nitrogen oxide emissions, which are considered a criteria pollutant, and explore alternative methods for measuring low-level emissions.
