  • Nanobots: each with their own tiny “brain”

    March 13th, 2008 at 10 pm. No Comments - Category: Computer, Medicine, Science -

    Steven Kehoe at mytechnews.org reports on advances in nanotechnology at the National Institute for Materials Science in Tsukuba, Japan. This is certainly a further step in the direction of smart nanoscale robots:

    “A tiny chemical “brain” has been invented by Scientists at the National Institute for Materials Science in Tsukuba, Japan. With a size of two nanometers, the molecular device is capable of controlling eight of the microscopic nanobot machines simultaneously.”

    And:

    “…it wouldn’t be feasible to put the nanobots into the blood and expect it to locate the right place, but this “brain” could fill that void. Dr Bandyopadhyay believes that the nanobots might come up as a miracle cure for certain diseases in the future, if the chemical brain could accurately control and guide the nanobots through the body.”

    Nice research being done at Tulane University by doctoral candidate Arman Sadeghpou about replacing Fluoride in toothpaste with an extract made from Cocoa/Chocolate. Bringing various benfits like “harden teeth enamel, making users less susceptible to tooth decay”, plus avoiding the dangers of fluoride, especially for children. Currently animal testing has been done and was proven to be successful.

  • University of Florida Research: Brazilian “Acai” Berry Destroys Cancer

    AcaiGAINESVILLE, Fla. — A Brazilian berry popular in health food contains antioxidants that destroyed cultured human cancer cells in a recent University of Florida study, one of the first to investigate the fruit’s purported benefits. Published today in the Journal of Agricultural and Food Chemistry, the study showed extracts from acai (ah-SAH’-ee) berries triggered a self-destruct response in up to 86 percent of leukemia cells tested, said Stephen Talcott, an assistant professor with UF’s Institute of Food and Agricultural Sciences. “Acai berries are already considered one of the richest fruit sources of antioxidants,” Talcott said. “This study was an important step toward learning what people may gain from using beverages, dietary supplements or other products made with the berries.” Read Article.

  • Phthalocyanin: Blue Jeans Dye against Cancer

    October 31st, 2006 at 8 pm. No Comments - Category: Medicine -

    “The dye in your blue jeans could soon be used to kill cancer cells, say scientists. UK researchers are employing tiny gold “nanoparticles”, 1/5000th the thickness of a human hair, to deliver the chemical compound directly into cancer cells, tearing them apart instantly. The common dye found in blue jeans and ballpoint pens is called phthalocyanine and is a light-activated, or photosensitive, agent with cell-destroying properties. This has been known for at least 15 years but, until now, scientists have not been able to successfully deliver it into cells; hence there’s no harm in wearing blue jeans.” BBC news.

  • Is Sex really necessary?

    October 26th, 2006 at 5 pm. No Comments - Category: Fun, Medicine -

    “Fans of abstinence had better be sitting down. “Saving yourself” before the big game, the big business deal, the big hoedown or the big bakeoff may indeed confer some moral benefit. But corporeally it does absolutely zip. There’s no evidence it sharpens your competitive edge. The best that modern science can say for sexual abstinence is that it’s harmless when practiced in moderation. Having regular and enthusiastic sex, by contrast, confers a host of measurable physiological advantages, be you male or female. (This assumes that you are engaging in sex without contracting a sexually transmitted disease.) In one of the most credible studies correlating overall health with sexual frequency, Queens University in Belfast tracked the mortality of about 1,000 middle-aged men over the course of a decade. The study was designed to compare persons of comparable circumstances, age and health. Its findings, published in 1997 in the British Medical Journal, were that men who reported the highest frequency of orgasm enjoyed a death rate half that of the laggards. Other studies (some rigorous, some less so) purport to show that having sex even a few times a week has an associative or causal relationship with the following:” Jump to article at forbes.com.

  • Lizard Saliva against Diabetes

    “If we needed another reason to stop the extinction of animals and plants around the world, the new medication derived from the saliva of the giant Gila monster desert lizard may be one. In three companion articles published Tuesday, September 26, 2006, in The Arizona Republic, Phoenix’s daily newspaper, reporter Connie Midey examined the excitement about a new diabetes medication based on the venomous saliva of the Gila monster. The creature is native to the Sonoran Desert of the American Southwest and northern Mexico, and a protein in its venom is the source for the new medication Byetta, manufactured Eli Lilly and Amylin. Not to be confused with the hallucinogenic and psychedelic venom of the Sonoran Desert toad, the substance in Byetta is a synthetic form of the protein which is secreted from grooves in the Gila monster’s teeth.” The rest of the article over at UFODigest.

  • People in Vegetative State Can Communicate Through Thoughts

    September 11th, 2006 at 2 pm. No Comments - Category: Medicine, Science -

    Apparently a percentage of people who are in a so called “vegetative state” are actually “conscious” and can respond when spoken to. This is an amazing insight and discovery. Specially when I think of the many cases where people are let die. There seems to be a new way now to find out for sure if someone is responsive: You ask them a question and they answer by “thinking the answer’! Scientist have found out that people can follow instructions and found out if they followed them by comparing brain patterns to healthy people. They noticed the displayed activity patterns where the same. Read more in this article by Medical News Today.
