Researchers have identified two large subglacial lakes in East Antarctica, which may harbor exotic ecosystems. Additionally, a study found that global sea levels likely rose by 195 millimeters between 1870 and 2004, with a rate of 1.7 +/- 0.3 mm/year.
PULMOTENSION aims to uncover underlying molecular pathways of PH, identify distinct targets for anti-remodelling therapy and test new treatment options in preclinical and clinical trials. The combined expertise in PULMOTENSION extends from gene mutation discovery to therapeutic regimen establishment.
The Times-Picayune won a special award for its consistently excellent coverage of scientific research on the vulnerability of New Orleans to hurricanes and other environmental impacts. Michelle Nijhuis, writing for High Country News, won the Walter Sullivan Award for her three-part series on global warming in the West.
A study led by Dr. Richard Goldberg found that the chemotherapy regimen FOLFOX4 is effective in treating colorectal cancer regardless of age, including older patients over 70. The analysis of nearly 4,000 patients showed consistent benefits and side effects across all age groups.
Research reveals farmed salmon have evolved genetically differently to wild salmon, backing claims of negative impact on health. The study found 20% difference in genes and potential for hybridization altering wild salmon's fitness.
Researchers found that moderately thin models have a positive impact on women's self-perception of thinness and self-esteem. In contrast, extremely thin or moderately heavy models can lead to negative thoughts about weight. The study sheds light on the effectiveness of campaigns featuring plus-sized models.
Researchers found that parents' conflict resolution styles predict children's reactions to simulated phone conflicts, with both overtly hostile and indifferent approaches linked to increased distress. Children's prior experiences with parental conflicts can alter their coping mechanisms for later conflicts.
Researchers found that low self-monitors are more responsive to self-prediction, which involves predicting one's own behavior, whereas high self-monitors are more influenced by situational factors. This technique can be a simple tool to boost motivation and commitment to resolutions.
A study found that receptors on brain nerve cells bind to apolipoprotein E and glutamate, affecting memory formation. Efficient APOE levels may clog these binding sites, preventing glutamate from activating processes necessary for memories.
A new computer chip lithography method, evanescent wave lithography (EWL), has been developed at Rochester Institute of Technology, allowing for optically imaging the smallest-ever semiconductor device geometry. The breakthrough has enabled resolution smaller than one-twentieth the wavelength of visible light, surpassing previous limits.
A study at the University of Texas M. D. Anderson Cancer Center found that Z-DNA, a twisted shape of DNA, can cause genetic instability and breaks in human cells, particularly in those with Burkitt's lymphoma. The research opens up a new field of inquiry into the role of DNA shape in genomic instability and cancer.
A multi-hospital project led by the University of Michigan Cardiovascular Center improved angioplasty care, increasing preventive medication use, reducing heparin and dye, and lowering complication rates. The study found a strong association between quality improvement efforts and patient outcomes.
A new study by Aradhna Krishna found that when blindfolded, subjects perceived the shorter glass with a wider surface area as having a larger volume. The study also revealed that visual distractions can influence consumer perceptions and behavior.
A new study suggests that a vaginal gel containing the antiretroviral drug tenofovir may be effective in preventing HIV transmission in women. The gel produced mild or no side effects in both HIV-positive and negative women, but further studies are needed to evaluate its effectiveness.
The RAVE survey has released its first dataset, containing information from 25,000 stars born when the Milky Way was in its infancy. The data will allow astronomers to test ideas of the galaxy's origins laid out by various cosmological theories.
Researchers found a direct link between aldosterone levels and the ability to hear normally as people age. Lower blood levels of aldosterone are associated with severe hearing loss, suggesting that the hormone plays a role in maintaining good hearing.
Scientists study Cu3Au alloy's corrosion behavior, observing the formation of a protective passivation layer that protects against further corrosion. Controlled corrosion allows for nanometric-scale material structuring, potentially leading to new catalysts with high surface areas.
A study published in the Journal of Consumer Research suggests that emotions like guilt and regret play a critical role in motivating people to make wise decisions about self-protection. The research finds that appeals combining fear and accountability are more effective than those relying on hope or good intentions.
Merchant identified a critical protein molecule that measures copper levels and responds to its presence in green algae, shedding light on the adaptive mechanisms of life. Her research has implications for human nutrition and may reveal new strategies for allocating essential nutrients.
A study published in Mayo Clinic Proceedings found that 22.4% of people with chronic pain did not inform their physician about it, likely due to poor experiences or barriers to healthcare. The study highlights the need for better pain management and increased awareness among healthcare professionals.
Researchers at Duke University have shown that hydrogen bonds are crucial for protein folding and are highly conserved across different proteins. Their study found that deleting hydrogen bonds from proteins led to destabilization of the structure, supporting the importance of these bonds in protein folding.
