New Light-Activated Nanoparticles Kill Over 90% of Antibiotic-Resistant Bacteria Bacterial Resistance to Antibiotics is a growing Problem around the World, Responsible for Some 2 Million Infections in the US each year that lead to approximately 23,000 Deaths. But a new Nanoparticle Treatment developed by Researchers at the University of Colorado Boulder could provide an effective means of Fighting Antibiotic-Resistant Bacteria including Salmonella , E. coli , and Staphylococcus, based on Results in a Laboratory Environment. In testing with a Lab-Grown Culture, The Nanoparticles killed 92 Percent of Drug-Resistant Bacterial Cells while leaving the other Cells intact. The treatment consists of Light-Activated Nanoparticles called  Quantum Dots. These extremely Small Particles, Which resemble the Semiconductors used in Electronics, are about 20,000 Times smaller than a Human Hair, and when excited by Light they prove deadly to Drug-Resistant Bacterial Cells. ...

For the First time, An international team of  Neuroscientists  has Transmitted a Message from the  Brain  of One Person to Another.     The team, which includes researchers from Harvard Medical School’s Beth Israel Deaconess Medical Center, the Star lab Barcelona in Spain, and Axilum Robotics in France, has announced today the successful transmission of a brain-to-brain message over a distance of 8,000 kilometers. "We wanted to find out if one could communicate directly between two people by reading out the brain activity from one person and injecting brain activity into the second person, and do so across great physical distances by leveraging existing communication pathways,” said one of the team,  Harvard’s Alvaro Pascual-Leone in a press release.  "One such pathway is, of course, the Internet, so our question became, 'Could we develop an experiment that would bypass the talking or typing part of internet and establish direct ...

Drug of choice is that drug which is known to be most effective in order to cure an infection or disease. A drug of choice should be accessible, cost effective, easily tolerable, safe, and most importantly effective against the disease-causing pathogen. Following is the list of few of drugs that are used in the common infections. Dr. Deepak Kumar Pathogen Disease Drug of Choice Actinomyces Actinomycosis Penicillin G Bacillus anthracis Anthrax Ciprofloxacin, Tetracyclines Bordetella pertussis Whooping cough Erythromycin Borelia burgdorferi Lyme disease Tetracycline Campylobacter Acute inflammatory diarrhea Ciprofloxacin Candida Vaginal candidiasis Systemic candidiasis Miconazole Fluconazole Chlamydia trachomatis Pelvic inflammatory disease Doxycycline Chlamydia pneumonia Pneumonia Tetracycline H. influenza ...

Scientists have made Human Egg and Sperm Cells using Skin from two Adults of the same Sex. DEEPAK KUMAR  06 MACH 2015 For the first time, scientists have shown that it’s possible for two people of the same sex to create a baby, without the need for outside egg or sperm donation. The most obvious benefits would be for homosexual couples who want to have a child together, but the method could also help couples who have been affected by infertility. The team, from Cambridge University in the UK and Israel’s Weizmann Institute of Science, built on previous work where baby mice were successfully raised from mouse skin cells that had been converted into what’s known as  primordial germ cells - the precursors of egg and sperm cells. It was a real struggle to replicate the process using human biological matter, but now they’ve finally managed to create new human primordial germ cells using skin cells from five human donors and stem cell lines from five human embryos. ...

Scientists discover the strongest known natural material in the world Move over, spider silk, there's a new super-material in town. TARUN ALEX  04 MARCH 2015 Spider silk is pretty amazing. It has the tensile strength of a  high-grade steel alloy , and about half that of the synthetic woven material,  Kevlar . It also has just a sixth of the density of steel, which means you could take a strand that’s long enough to wrap around the whole Earth, and  it’d weigh less than 500 grams . This quality means that spider silk would be five times as strong as the same weight of steel. And while we can’t take away from its incredible properties, we just might have to take away its title of ‘strongest natural material’, because researchers have figured out just how strong the teeth of  limpets , a type of marine snail, are. “Until now, we thought that spider silk was the strongest biological material because of its super-strength and potential applications i...

New research suggests that drinking just one can of caramel-coloured soft drink a day could expose you to unsafe levels of a possible carcinogen. DEEPAK KUMAR   04 MARCH 2015 Soft drinks have never been the most nutritious dietary choice, but new research suggests that an unnecessary coloring ingredient may pose a cancer risk, even to people who consume an average amount of soda. And here's where the problem lies, because 4-MEI has been classified as possibly carcinogenic to humans by the International Agency for Research on Cancer, as a result of " equivocal evidence of carcinogenic activity in female rats ", but no human studies. The chemical in question is a byproduct of caramel colour, a common ingredient that gives colas, root beers and iced teas their dark hue. During production of caramel colour type III and IV, a chemical known as 4-methylimidazole (4-MEI) can be produced.  Of course, that doesn't mean the chemical definitely causes cance...
