A new study found that highly paid workers reported more cohesion and solidarity among their colleagues, and were more likely to participate in social activities with co-workers. Highly paid workers tend to have jobs with more freedom and autonomy, leading to richer social lives.
Researchers found six HIV patients who started treatment early became test-negative for the virus. The study suggests that reducing HIV to low levels can help boost the immune system's response to the virus.
Researchers found that sphinx moths can learn to associate specific odors with food, demonstrating a complex learning process. The study's findings have wide-ranging applications, including potential uses in defense industry and law enforcement for detecting biological and chemical weapons.
Researchers at Georgia Institute of Technology and NASA found that nanosprings exhibit mechanical properties similar to macroscale springs. The findings suggest other nano materials may behave similarly to their macroscale counterparts.
Roland Glowinski, a renowned mathematician at the University of Houston, has been awarded the Theodore von Kármán Prize for his sustained outstanding contributions to mechanics and applied computational mathematics. He will give a special lecture on numerical simulation of incompressible viscous flow with moving or free boundary: appli...
Researchers found that changes in Notch and Distal-less gene expression mark early events in the evolution of eyespots and intervein patterns. The study demonstrates how dramatic evolutionary changes occur through simple changes in gene regulation timing.
The Virginia Tech National Bioinformatics Resource Center will focus on Brucella, Caliciviruses, hepatitis A, Rabiesvirus, and Coxiella burnetii/Rickettsias. The center will enable researchers to access, analyze, and study molecular data for these infectious diseases.
A new study reveals a previously unrecognized mechanism for blood vessel patterning, suggesting a potential therapeutic target for cardiovascular diseases. The discovery involves an endothelial receptor called PlexinD1, which may enable manipulation of blood vessel growth and development.
A recent study by Takayuki Onai et al. reveals that XsalF, the Xenopus homolog of spalt, regulates forebrain and midbrain-specific gene expression. The research demonstrates direct linkage between XsalF expression and forebrain/midbrain identity.
A study published in Archives of Surgery found that patients who underwent Roux-en-Y gastric bypass surgery experienced significant declines in ghrelin levels, a hormone that stimulates appetite. The findings suggest that complete division of the stomach contributes to this decline and may play a key role in weight loss.
The report recommends the development of antiviral drugs against smallpox due to its high lethality and ease of transmission. Research on poxvirus mechanisms and animal models is crucial to understand how the virus kills and develop effective treatments without using antiviral drugs.
A study found latanoprost to be safe and well-tolerated in reducing intraocular pressure (IOP) for patients with primary open-angle and exfoliation glaucoma. The researchers also reported a mild incidence of increased iris pigmentation, primarily affecting patients with green-brown or yellow-brown eyes.
