Researchers investigated the effects of caffeine (SRC) and melatonin (Mlt) on jet lag symptoms. The study found that Mlt decreased subjective sleepiness but not objective sleep quality, while SRC reduced sleepiness for a few days with negative effects on recovery sleep. Additional studies are needed to evaluate their full effects.
The Severn Estuary Partnership has received £150,000 funding to improve and develop sustainable access to and around the estuary. The project aims to boost local economies by promoting local produce and enhance nature conservation values.
Researchers develop gene therapy to enhance islet cell function and survival after transplantation. The technique uses a growth factor DNA to induce cell division, improving insulin production and glucose control in rat models. However, standard immunosuppression drug therapy may be harmful, inducing insulin resistance and diabetes.
A team of international researchers, including University of Colorado at Boulder professor Robert Hohlfelder, are searching for the lost fleet of Persian warships in the seas off Greece's northern coast. The team used sonar, a manned submersible submarine and a remotely operated vehicle to locate the site, which was chosen after local ...
Researchers have discovered a link between cystic fibrosis and fatty acid defects, with abnormally high levels of arachidonic acid and low levels of docosahexaenoic acid found in patients. The study suggests that correcting this imbalance may lead to new treatment options for the disease.
Rensselaer Polytechnic Institute researcher is developing a compound to neutralize anthrax toxin, which could be injected into healthy humans as a preventive measure or given to infected individuals as an antidote. The goal is to develop a safe and effective treatment for bioterrorist anthrax attacks.
Researchers at Purdue University developed a miniature device sensitive enough to detect a single virus particle, with applications in environmental health monitoring and homeland security. The device uses a tiny cantilever that vibrates at a specific frequency when a virus particle lands on it, allowing for real-time detection.
Researchers used post-mortem spinal cord tissue to identify a unique gene expression profile in ALS patients, revealing distinct changes underlying the terminal stages of the disease. The study distinguishes between familial and sporadic ALS forms, providing insights into the molecular pathophysiology of neurodegeneration.
A membrane protein called NCX1 plays a crucial role in regulating the frequency and strength of heartbeats by transporting calcium into and out of heart cells. The protein generates electrical currents that contribute to excitation and contraction, making it an important key to understanding cardiac function.
The study found that school sports participation was associated with lower odds of currently smoking cigarettes. However, both chewing tobacco and snuff use were higher among athletic adolescents, indicating that sports do not help keep students away from less incendiary forms of tobacco.
Researchers found that 68% of patients experienced a reduction in pain intensity of greater than 33%, indicating promising relief. The biotoxin blocks slow sodium channel nocicipetive pain fibers in a highly selective way, making it a potential treatment option for cancer pain.
Researchers at Massachusetts General Hospital developed a strain of mice with the c. elegans gene fat-1, which converts omega-6 acids to omega-3s. The transgenic mice produce high levels of omega-3 fatty acids, opening up possibilities for farm animals that naturally produce omega-3 rich food products.
A new procedure, carotid artery angioplasty with stenting (CAS) with distal embolic protection (DEP), has shown zero neurological complications in a study involving 21 patients. The minimally invasive technique adapts techniques used to open heart vessels for brain arteries, significantly reducing risk of stroke and death compared to t...
Researchers found that Dahl R rats exhibit efficient spatial navigation, while Dahl S rats display poor spatial navigation. Analysis of F1 male progeny implicated the X chromosome in the impairment observed in Dahl S rats.
A study found that menthol cigarettes, like Newport, are more attractive to teens, while brand-name cigarette use is concentrated among adolescents. The researchers also discovered that tobacco advertising and promotion budgets increased significantly during the 1990s, contributing to the popularity of certain brands.
The study found that 82% of patients had polycystic ovary syndrome (PCOS), while 6.75% had specific identifiable underlying disorders. Combination hormonal therapy improved most symptoms, including hirsutism, acne, and menstrual dysfunction in 86%, 81%, and 80% of cases respectively.
A study analyzing HMO medical groups found that with efficient care, primary and specialist physicians can serve a large patient population with significantly fewer doctors. The HMOs had about 1 physician for every 650 patients, compared to the current US supply of 1 per 400.
The Acoustical Society of America sponsors two annual awards for outstanding popular works on acoustics. Entries must be published or broadcast between January 1, 2003 and December 31, 2003, and meet criteria for accessibility, relevance, accuracy, and quality. The winners will receive a $1000 prize and an award certificate.
Babytalk plays a crucial role in infants' development of temporal arts, such as literature and music. Depriving babies of poetic elements like alliteration and assonance may hinder their ability to appreciate these arts later on. Researchers argue that babytalk is more significant than previously thought.
A study of 3,288 teenage girls found that those with multiple sexual partners were more likely to have unprotected sex and experience negative health consequences. Girls tend to limit their partners as they progress through high school, but education before ninth grade may help reduce these risks.
Graduate student Sommer Gentry investigates haptic communication in swing dancing and its potential applications in robotic surgery, human-robot collaboration, and urban warfare. Her research has shown that pure haptic communication is sufficient for humans and robots to move in coordination.
Rising star in chemistry, Jianpeng Ma, has made significant breakthroughs in understanding the structure-function relationship of biological molecules. His innovative approach uses computer simulation to explore this connection, paving the way for furthering our fundamental understanding of chemistry.
Researchers have created a strain of mouse whose muscle cells continuously produce mIGF-1, leading to significant muscle regeneration and tissue repair. This breakthrough sheds light on how stem cells specialize and integrate into damaged tissues.
