New Hopes in Stem Cells Human embryonic cells remain a research tool to study the mechanisms of disease. There will be many therapeutic benefits. We will be able to produce new drugs. Thomas M. Messell, a neurobiologist at Columbia University Medical Center in New York, stated he hoped to see the research generate new drugs for neurodegenerative disease. He expects a revolution within the next 5 years. Scientists have spent the last 5 years in how to grow the cells in the lab an...
Why smoking is an addiction? New imaging studies of the smokers show that nicotine causes the addiction. A few puffs of cigarette can exert a force powerful enough for the individual to continue smoking. For this reason we see people become chain smokers. According to Archives of General Psychiatry, the drug therapies of smoking cessation need to be extremely potent to compete with nicotine. Only one puff of cigarette can occupy 30% of brains common type of nicotine receptors. Stu...
Married People Lives More According to a new research, marriage can be good for health. A survey of 80,000 Americans showed that people who were never married were 58 percent more likely to die than their married peers. Compared with people who live with their spouses, those who were divorced were 39 per cent more likely to die during the follow-up period. Marriage, social institution uniting men and women in special forms of mutual dependence, often for the purpose of found...
Deficiency of Vitamin E in Pregnant Women According to a study in The American Journal of Respiratory and Critical Care Medicine, pregnant women who do not get enough Vitamin E may have children who are at a higher risk of suffering from asthma. The research reveals that the early life nutrient intake, both in the utero and post partum period, modifies the risk of developing childhood asthma. Postpartum period is the after delivery period. Utero period is the period when the baby i...
Nanoparticles and human cells Scientists at Brookhaven National Laboratory in New York have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. This study throws light on how human cells interact with carbon nanoparticles. These experiments will give insight into the design of nanoparticles keeping in mind safety concerns and optimizing their use in health related applications. It may also le...
Cows communicate in regional accent! The farmers of London found that the cows communicate in their regional accent. The cows have a single syllable to communicate but they do it in using a regional accent as the study tells us. The cows have limited conversational skills. The herds in the West Country are mooing in their distinct Somerset twang. Some listeners describe this sound as “moo-arr” rather than moo. John Wells, professor of phonetics at the University of London thinks ...
Researchers have demonstrated that Prozac, a commonly described antidepressant, can interfere with the reproductive cycle of freshwater mussels. Fluoxetine sold, as Prozac TM, acts to increase the levels of serotonin at nerve synapses, relieving depression. But for a number of aquatic species, serotonin moderates the reproductive system. Tests found fluoxetine causes female mussel larvae to release them prematurely. The research aims to understand the impact of pharmaceuticals in waste wa...
Disruption of a family member’s treatment for mental illness and subsequent worsening of psychiatric symptoms can have harsh financial, physical and emotional consequences for families. This is the result of an international survey of caregivers of individuals with schizophrenia, bipolar disorder, and schizoaffective disorder. Preston J. Garrison, the secretary general and chief executive officer, World Federation of Mental Health states parents, siblings, spouses, and children connected ...
Researchers at John Hopkins have evidence that curbed activity from several key chemicals on the inner lining of the nose is linked to chronic sinusitis. Some chemicals fails to respond to current treatments. According to U.S. Centers for Disease Control and Prevention, persistent inflammation of the moist tissue that lines the nose and sinus cavities results in clogged passages and recurring infections. The team of scientists found that the activity of at least 4 genes were seriously de...
Silicon is the edifice of electronics revolution. With the help of silicon, microchips are made and they are used as integrated circuit (I.C.) in a variety of electronic appliances like TV, computer, etc. Transistors made of silicon switch electric current on and off. In a single silicon chip there are hundreds of thousands of tiny transistors. As a result, the size of a computer in the early stage was as large as a room, which later shrank to pocket-sized PC. In the Univ...
Cranberries acting as antibiotics Cranberries have a kind of tannins. This can transform E. coli bacteria. The organism Escherichia coli, a common intestinal organism that is widely used in genetic engineering, is a eubacterium. Scientists at Worchester Polytechnic Institute, the ways that render them unable to initiate any infection. The study shows the compounds that affect in E. coli in 3 devastating ways, all of which prevented the bacteria from adhering to cells in the body. ...
According to a report on the journal Science, the unusual molluscs of oceanic cold sweeps ---strange clams, mussels, and sea snails --- that thrive on the sulfur and methane rich environments ---- are on average older than marine mollusk rich community as a whole. Cold sweeps may have been safer harbors for the mollusks. It protects them from mass extinction. Due to the hydrogen sulphide and methane leak through the oceon floor, a unique chemical environment is created where the ha...
Spectroscopy And Chromatography Technology Replaces Winetasting In San Francisco a winemaker is using analytical chemistry to supplement the technique of winetasting. Winetasting is a time-honored practice of tasting a mouthful of grapes to determine when the fruit is ready for picking. Now spectroscopy and chromatography replaces this technique. This new technique evaluates the aroma, color and taste of grapes. Grapes can be analysed for their molecular makeup. Molecules indicat...
Vitamin C enhances heart functioning Vitamin C supplements improves the nervous system of the patient suffering from heart attack. According to International Journal of Cardiology, researchers found ascorbic acid on the sympathetic response to exercise in 21 men. After an oral administration of the supplements, the participants undergone symptoms-limited exercise testing twice. Once after oral administration and once without. The resting blood pressure and heart rate did not diffe...
Scientists studying equine evolution have assembled the genetic blueprint of a thoroughbred mare. A rough draft of its entire DNA sequence has been made. They wanted to study physiology and dozens of diseases of both horses and human. At Broad Institute in Massachusetts, the research was done under a senior scientist named Clair Wade. The genome contains sizeable gaps and more analysis is needed. The research team estimated that 2.7 million units of DNA would provide a huge informati...
