Researchers found that stress increases triglycerides in the bloodstream, which can contribute to heart disease. Triglyceride levels declined more slowly in stressed volunteers compared to those who rested, suggesting a negative impact of stress on fat metabolism.
Researchers found that plants inherit traits from factors outside of genes, such as DNA modification and packaging, which can be passed on to offspring. The study suggests a cost of resistance in plants, where hyperactive defense systems lead to physical damage despite low disease threat.
A new study has found a significant association between activity in the ventromedial prefrontal cortex and individual differences in mood. The researchers used brain imaging techniques to record brain activity in 89 individuals, who were asked about their experiences with unpleasant moods.
The Ecological Society of America advocates for a broader view of freshwater resources, prioritizing ecological needs alongside societal requirements. Healthy freshwater systems provide essential goods and services like food supply, flood control, and habitat, which are costly to replace with technology.
Researchers at Northwestern University have developed a gene therapy that reduces inflammatory cytokines involved in joint inflammation. The treatment, which uses the IL-13 gene, has been shown to suppress joint inflammation and prevent the development of arthritis in rat models.
A study by scientists at the Medical College of Georgia and others found that autistic patients have significantly smaller minicolumns, a basic organizational unit of brain cells, but more of them than controls. This may be consistent with an existing theory that autistic individuals suffer from overarousal and abnormal behaviors.
Researchers at Tufts University have engineered custom-made human knee ligaments using adult stem cells, offering a potential solution to the costly and debilitating ACL reconstruction process. The new tissue engineering strategy could significantly reduce recovery time for professional athletes and sports enthusiasts.
Researchers found a correlation between older adults' use of speech and their ability to gesture, with more words spoken leading to lower scores on pantomime tasks. The study suggests that speaking may interfere with gesture production or be used as a substitute response to activate gestures.
A new study finds that global warming will increase the length of the day by 0.11 seconds over the century due to changes in Earth's angular momentum. The effect is expected to be small and difficult to distinguish from natural variations, but measurable on a decade scale.
The center aims to increase opportunities for underrepresented minority researchers, educators, and clinicians in the biomedical research community. It also seeks to create a nationally recognized model for addressing racial and ethnic health disparities through campus and community partnerships.
The TIMED spacecraft is beginning its two-year science mission to study the influences of the sun and humans on the least explored portion of Earth's atmosphere. The mission will provide a global picture of this critical region, enabling future 'space weather' predictions.
The Keck Foundation is funding a $750,000 grant to develop a 3D fusion microscope at Northeastern University. The instrument will enable three-dimensional imaging of biological specimens using five advanced technologies, with applications in embryonic development and spinal cord injury research.
Levels of nitrogen and sulfuric acid have decreased moderately in some Adirondack lakes, suggesting a decline in acidic levels. Long-term data is needed to confirm the changes and understand the underlying causes.
Erik Westman aims to reduce fatalities, lower construction costs, and improve environmental protection through a practical method for predicting failures in rock masses. He's adapting tomographic imaging technology for field use, enabling engineers to monitor stress redistribution in rock masses.
The innovative procedure uses a 40-second CT scan to identify colon polyps, reducing the risk of puncturing and sedation. Virtual Colonoscopy has been shown to detect polyps as small as 3mm in diameter with high accuracy.
