A study using genetically engineered mice suggests that Ritalin calms humans with attention deficit hyperactivity disorder (ADHD) by affecting serotonin levels, rather than dopamine. The findings provide a new understanding of the drug's mechanism of action and could lead to more effective treatments for ADHD.
The American Chemical Society's spring national meeting will discuss various topics including obesity treatment and the use of geochemicals to detect extraterrestrial life. Over 5,000 scientific papers will be presented to an estimated 10,000 attendees.
Researchers found that COX-2 inhibitors suppress prostacyclin, a hormone-like substance produced in blood vessels, which can lead to increased thrombosis risk. This discovery raises concerns about the potential cardiovascular risks of these new pain relievers.
Researchers at Max Planck Institute find collisions between light and heavy atoms favor ozone formation, advancing understanding of large isotope effect in heavy ozone. The discovery refutes molecular symmetry theories and highlights the role of specific reaction channels in ozone molecule production.
A multi-centered study led by Dartmouth Medical School found that supplementation with calcium can reduce the recurrence rate of large bowel adenomas in people with a history of these particular polyps. The findings suggest promising measures that are fairly simple and inexpensive to help prevent colorectal cancer.
Scientists from the University of Montana and HHMI successfully produced broadly effective antibodies against HIV by capturing the virus's infective machinery in the moment it fuses with a target cell. The new approach outperforms previous efforts, which only neutralized laboratory-grown strains.
Ritalin and other stimulants appear to restore balance between dopamine and serotonin, calming hyperactivity. The study suggests that targeting serotonin may be a more effective approach to treating Attention Deficit Hyperactivity Disorder (ADHD) than previously thought.
Joel Brawley, a renowned mathematics professor at Clemson University, has been awarded the MAA's Deborah and Franklin Tepper Haimo Award for Distinguished College or University Teaching. The award recognizes his exceptional teaching effectiveness and its impact beyond his institution.
Researchers have identified two genes crucial for auxin transport, a process vital for plant growth and development. The discovery sheds new light on how plants regulate growth and has significant implications for the agrochemical/biotechnology industries.
A recent study found that 5% of North Carolina middle school boys carried guns, while 20.2% carried clubs or knives, with both linked to substance use and violence. The study suggests that similar prevention programs should be introduced in elementary schools, along with substance use prevention.
A national survey of family physicians, general internists, and obstetrician-gynecologists found that more than 90% are confident in diagnosing depression. Despite improvements, there is still room for growth in treating depression with high-quality care.
Researchers have developed a process called hierarchical self-assembly, where hollow spheres stack themselves into larger structures to form photonic crystals. These materials can manipulate light in predictable ways, offering potential applications in optical data storage, telecommunications, and lighting systems.
