Invisible toxins in your home

December 6, 2010

Exposure to indoor pollution is associated with allergies, severe asthma, hospitalizations for cardiovascular and respiratory disease, and even heart attacks.

Having a clean home doesn’t keep the toxins and pollutants away.  According to the EPA, pollution in the home is often 2 to 5 times higher than it is outdoors.  “The air in your house contains pollen, mold, and ozone that leach in from the outdoors, as well as pet dander and pollutants from household cleaning products,” says Ted Myatt, ScD, a senior scientist at the consulting firm Environmental Health and Engineering, Inc.

Come winter, weatherproofing combined with heated, dry air can boost indoor pollution levels even higher by sealing in airborne toxins and lowering levels of humidity. The combination of the two can pose an even greater risk. “Exposure to indoor pollution is associated with allergies, severe asthma, hospitalizations for cardiovascular and respiratory disease, and even heart attacks,” Dr. Myatt says.

Considering we spend about 60% of our lives in our homes, it’s time to clear the air. Check-out this article to find out what you can do help reduce the toxins and pollutants in the home.

Insect brains…a new antibiotic?

September 15, 2010

American cockroachStudies have shown that the central nervous systems of American cockroaches produce natural antibiotics that can kill off bacteria often deadly to humans, such as methicillin-resistant Staphylococcus aureus (MRSA) and toxic strains of Escherichia coli.  The findings suggest that the insect world—which makes up 80 percent of all animals on Earth—may be teeming with new antibiotics.

What will cell phones do next….give eye exams?

Smart phone eye examination lens

With all of the things that a smart phone can do, who thought that an eye exam would be one of them?

Scientists at MIT recently developed an app that when combined with a $2 optical lens can give an accurate eyeglass prescriptions.  Once the app is loaded, the user attaches a short, conical viewfinder to the screen of their high resolution cell phone and peers in. The app then checks the four various axis of the eye.  The app not only checks the user’s vision, but also checks for other abnormalities such as astigmatism.  From start to finish, it takes about two minutes to deliver a full prescription.  What will they think of next??

Gel that helps heal brain injuries

July 1, 2010

SBraincientists from Clemson University in South Carolina have developed a gel that has the potential to treat head injuries suffered in combat, car accidents, falls, or gunshot wounds.  The gel is injected in liquid form at the site of injury and stimulates the growth of stem cells there.

The gel can be loaded with different chemicals to stimulate various biological processes at the site of injury, which makes the treatment of brain injuries more effective.

European Scientists Advance Biometrics

Scientists at Italy’s University Campus Bio-Medico of Rome recently announced an advance in thought-controlled biometric devices.  A biometric hand was surgically attached to the patient’s nervous system via implanted electrodes. After the surgery in November 2008, it took the patient just days to start using the hand.  During the one month trial, the patient was able to experience sensations when making the most complex movements ever documented by a biometric limb.  Now, the challenge is to connect limbs for years, not months.

Stem Cells Used To Grow New Skin

French doctors announced last week that they had used human embryonic stem cells to grow skin that may one day be used as potentially life-saving skin grafts for badly burned patients.  Currently when someone suffers a severe burn, their own skin cells are grown in the laboratory to provide replacement skin. But this process takes weeks and, while patients wait for skin grafts, they can suffer from a variety of complications.  Human testing of this skin has yet to occur, with mice the only test subjects so far.
