Scientists trying to create artificial life generally work under the assumption that life must be carbon-based, but what if a living thing could be made from another element? One British researcher may have proven that theory, potentially rewriting the book of life. Lee Cronin of the University of Glasgow has created lifelike cells from metal — a feat few believed feasible. The discovery opens the door to the possibility that there may be life forms in the universe not based on carbon, reports New Scientist . Even more remarkable, Cronin has hinted that the metal-based cells may be replicating themselves and evolving. "I am 100 percent positive that we can get evolution to work outside organic biology," he said.
This is some pretty exciting news. It seems that researchers at the Massachusetts Institute of Technology (MIT), one of the most prestigious science and engineering schools in the United States, has created a new energy source -- and it's clean and renewable. The odd thing is that the only way you can see this energy source is with a very powerful microscope, because it is created by using nanotechnology. For a few years now, we have been hearing about the possibilities offered by the new field of nanotechnology. Now it looks like the first usable breakthrough has been accomplished. MIT has devised a process to generate electricity using nanotechnology.
When it comes to birth control , it's a lot harder figuring out how to stop a bajillion little sperm than one little egg, but a scientist in India has managed to develop an injection for men that has so far proven to be 100% effective and completely reversible with no side effects. Sign me up. The injection is called RISUG, which stands for "reversible inhibition of sperm under guidance." Let's just get the uncomfortable bit out of the way first: you can't just be injected anywhere, the doctor has to stick a needle into your scrotum. Twice.
Last Updated: 3/23/2013 23:56 PST Did you know you can lose weight without traditional dieting? That’s what one new weight loss product wants you to believe, after claiming you can lose 30 pounds in six months, without depriving yourself†. It’s called the SENSA® Weight Loss System , and it’s one of the most talked-about weight loss products on the market today –featured in The New York Times, Time Magazine, and Dateline NBC. Some are calling the SENSA® diet “revolutionary” because of its radically new approach to weight loss. SENSA® boldly claims to help users lose significant weight.
CAMBRIDGE, Mass. -- In results that counter the idea that oxygen free radicals cause aging, an MIT researcher reports in the July 18 issue of Nature that calorie restriction prolongs life because it increases respiration, not because it decreases oxygen free radicals. MIT biologist Leonard Guarente believes "the conventional wisdom on oxygen radicals is dead wrong. Our results (in yeast) are contrary to the frequent suggestion that calorie restriction functions by slowing metabolism and thereby slowing the generation of free radicals." Guarente, who is working on a book on aging to be published this fall, discovered in 2000 that calorie restriction activates the silenced information regulator (SIR2) gene, which has the apparent ability to slow aging. This gene makes a protein called Sir2, which Guarente has shown is integrally tied to extending life span in yeast and in the roundworm. Humans carry a similar gene.
Imagine having a gun fired at you, the bullet whizzing toward you at a super-fast speed. But instead of the bullet piercing your skin and traveling deep inside your body, what if it instead repelled off your skin? What sounds like a scenario straight out of a superhero movie or a sci-fi novel could eventually become reality. Scientists have created a skin made with goat's milk packed with spider-silk proteins, according to news reports. Their hope is that they can eventually replace the keratin in human skin -- which makes it tough -- with the spider-silk proteins.
Let’s face it. Cardio is boring. Running laps around a track or pedaling away like some spandex wearing gerbil…..
A group of researchers, fro m the University of North Carolina at Charlotte, have mapped out 23 specific chromosomal locations that account for 84% of the behavioral differences between low activity (see lazy ) mice and high activity mice (see type A super achievers ) – sorry, no human tests yet. Link to Study # 1 Link to Study # 2 Initially, the researchers thought that the difference between the lazy and active mice was due to a genetic effect on the way energy is used by the muscle tissue. This was proven false.
Brown Fat Mitochondria or Modern Art? Researchers at the Joslin Diabetes Center have been researching ways to generate fat loss by stimulating brown fat production. In a recent study ( published in Nature ), they have shown that a protein called BMP-7 can promote the development of brown fat. This is good news. While the white fat cells that cover our doughy North American bodies are seen as the bane of our collective overweight existence, their brown fat cousins are superstars at burning calories. What?
