Researchers found that prion diseases adapt slowly to new species through a prolonged process, making early detection difficult. The study also showed that the disease can spread rapidly in new hosts under specific conditions.
Researchers found Thrombospondin-1 (TSP1) regulates tumor growth by suppressing MMP9 activation, which promotes angiogenesis. The discovery could lead to new treatments targeting malignancies by cutting off the blood supply to tumors.
C. elegans has a large number of genes due to its genetic makeup and the need for robust development and morphology. The worm's ability to fend off bacteria and other microorganisms in its soil environment is also thought to contribute to its high gene count.
A unique 5-year study will enroll 105,000 people, including two-thirds African-Americans, to identify key factors contributing to cancer development. The Southern Community Cohort Study will explore lifestyle and genetic factors linked to cancer disparities in the southeastern US.
The study found that estrogen receptors are more widely expressed in the brain during fetal and neonatal periods, influencing brain development. Antisense oligodeoxynucleotide treatment decreased brain estrogen receptor levels, leading to changes in ventilation and body growth in male and female rats.
This study reveals sex hormone effects on body fluid regulation and blood pressure, with men showing greater plasma AVP sensitivity to hypertonic saline infusion. This increased sensitivity is associated with higher systolic pressure, pulse pressure, cortisol levels, and sodium retention.
The center investigates factors that predispose elderly patients to hospitalizations due to medication errors, as well as sociological and organizational causes of medication errors among physicians. Its research focuses on reducing internal bleeding and kidney failure caused by medication errors.
Researchers from Bell Labs have created molecular-scale organic transistors that can rival silicon transistors in performance. The breakthrough could lead to thousands of times more transistors being squeezed into the same space as today's circuits.
A study by Professor Partha Dasgupta suggests that world poverty is far worse than traditional indicators like GNP per capita or HDI. This is because these measures fail to account for the depletion of natural capital, such as commercial forests and water, which are underpriced or free to those who use them.
Research reveals women exhibit a greater decrease in arterial pressure during recovery, with reduced cardiac output and lesser increases in vascular resistance. Engaging light activity supports arterial pressure, regardless of gender.
The Antarctic seafloor core suggests that Earth's orbital oscillations may be the key to controlling ice ages. The core shows regular intervals of ice sheet advances and retreats during a 400,000-year period, matching Milankovitch cycles.
A large study found that antidepressants, specifically selective serotonin reuptake inhibitors (SSRIs), may reduce the risk of heart attacks in smokers by 65%. The study also suggests that SSRIs may work by thinning blood and preventing clotting, similar to aspirin.
Researchers investigating immune system response to serious injury, including genetic elements, in hopes of identifying proteomic and genomic markers that could predict patient risk. The team also aims to develop standard operating procedures for treating burn and trauma patients.
Rutgers University has received significant funding from the National Science Foundation (NSF) for its information technology research projects. The university's computer science and engineering departments are among the recipients, with projects focused on pervasive computing, smart messages, and data analysis.
A new specialty license plate will fund whale research in Florida waters, with $25 registration fees going towards conservation efforts. The license plate will be unveiled at a ceremony in Destin, Florida, on October 17th and is expected to raise funds for whale-related research and conservation.
Researchers at UNC Chapel Hill have discovered the chemical mechanism behind 'skunky beer' caused by light-sensitive hop compounds called isohumulones. These compounds break down into free radicals when exposed to light, producing a skunky thiol molecule with an extremely low taste and smell threshold.
