A recent study by Emory University Health Sciences Center found that patients with depression are less likely to clear the hepatitis C virus from their blood after six months of treatment. Only 34% of those experiencing a significant increase in depression were able to clear the virus, compared to 59-69% of those with milder increases
Archaeologists have discovered over 250 new examples of England's finest array of prehistoric rock art carvings, which can now be admired on a comprehensive website. The site features 6,000 images, interactive games and audio clips, and is said to be the most extensive database of its kind in the world.
Researchers found that Whites perceive significantly more disorder than Blacks, Latinos, and Asians, even when living in the same neighborhood. The study suggests implicit bias in perceptions of disorder contributes to continued racial segregation in the US.
RHIC scientists observe intriguing data in gold-gold collisions, indicating the presence of a new form of matter. The copper experiments will provide control data to help understand how this phenomenon is produced and controlled.
Researchers at Northwestern University propose a new theory that challenges the widely accepted model of long-term memory storage. According to this new theory, memories are stored through a dynamic and meta-stable process, rather than permanent representation in the brain.
Researchers discovered three distinct scattering patterns as alky-thiol density increased, indicating different degrees of molecular order. The tilted phase exhibits crystalline patterns despite the disordered liquid nature of the underlying mercury.
The Georgia Medicaid program implemented a prior-authorization program for anti-ulcer drugs, resulting in a net savings of $20.6 million. The program increased the use of generic histamine type-2 antagonists and decreased PPI drug expenditures by $30.9 million.
The concentration of people and wealth in underground spaces poses significant risks from floods, tsunamis, and other extreme events. Modeling catastrophic events is crucial for designing contingencies such as evacuations and emergency containment.
Researchers at Texas A&M University have successfully levitated micron-sized fluids using small magnets on a postage-stamp sized chip. This innovation enables the control of tiny droplets and crystals, opening up possibilities for future research in DNA manipulation, nanotubes, and other areas.
Dr. Erkki Ruoslahti's pioneering work on cell adhesion has led to significant discoveries in cancer biology and its applications to various diseases. His contributions have elucidated the etiology and developed therapy for serious conditions like malignant tumors, heart attack, stroke, and osteoporosis.
A recent study published in the journal Cell has found that over 30% of human genes are controlled by RNA molecules, providing new insights into gene regulation. The researchers used computational methods to identify microRNAs that target specific genes, revealing a vast network of regulatory interactions.
Researchers have identified a previously unknown sequence on the human Y chromosome, containing eight potentially active genes. This discovery suggests that segmental duplications in pericentromeric regions may be underrepresented in current genome sequences.
Researchers found mitochondrial DNA mutations in 12% of prostate cancer samples and 7.8% of general population controls, with increased tumor growth and oxygen radical production in mutant cells. These findings suggest a causal link between mtDNA mutations and prostate cancer development, particularly in African men.
Researchers at UCSD have discovered a unique structure in abalone shells that can provide the basis for lightweight and effective body armor. The shells' layered structure, made of calcium carbonate tiles held together by protein adhesive, is theoretically the toughest arrangement possible.
Researchers at NYU developed a mathematical model that replicates the complex network of molecular interactions within a cell's circadian clock. The study found that rapid binding and unbinding of regulatory molecules is crucial for accurate timekeeping, contradicting the notion that more molecules lead to better accuracy.
Researchers found that chiral compounds, including organophosphates and synthetic pyrethroids, pose previously uncalculated toxic risks due to their biologically different behaviors. Using just the active isomer can achieve similar pest control with reduced chemical use and environmental benefits.
