The wonders of pharmacology keep appearing regularly, each new drug seemingly too good to be true.
A two year old girl born with arthrogryposis, a congenital disease that left her unable to lift her own arms, although able to walk, has been given a new lease on life by a 3D printed robotic exoskeleton, enabling her to move freely for the very first time. The exoskeleton, made of a similar material to Lego, was manufactured using a Stratasys Dimension 3D printer so as to create a prosthetic light enough for young Emma to continue walking around freely.
You are what you eat, the saying goes. And, according to two new genetic studies, you are what your mother, father, grandparents and great-grandparents ate, too. Diet, be it poor or healthy, can so alter the nature of one's DNA that those changes can be passed on to the progeny.
The scientists and other experts said the work was a giant step toward developing computerized laboratories that could carry out many thousands of experiments much faster than is possible now, helping scientists penetrate the mysteries of diseases like cancer and Alzheimer’s. “You read in the paper just about every week, ‘Cancer gene discovered’ or ‘Alzheimer gene discovered,’ ” said the leader of the new research, Markus W. Covert, an assistant professor of bioengineering at Stanford.
While creating Chanel No. 5, Coco resorted to an old perfumer’s trick: scrapings of sexual pheromones from the perianal gland of the Abyssinian civet cat Photograph by Thinkstock.
The tropical tree Moringa oleifera has a special quality that makes it very suitable for cleansing water.
Scientists have invented particles able to keep a person alive even if they are unable to breath.
Researchers at Weill Cornell Medical College have developed a vaccine that could help existing smokers quit for good and prevent those yet to try cigarettes from ever becoming addicted.

The accomplishment heralds an era in which parents might find it easier to know the complete DNA blueprint of a child months before it is born. That would allow thousands of genetic diseases to be detected prenatally. But the ability to know so much about an unborn child is likely to raise serious ethical considerations as well. It could increase abortions for reasons that have little to do with medical issues and more to do with parental preferences for traits in children.

Once upon a time, tasters were employed by the well-to-do, in order to check that their food or drink wasn't poisonous. Today, there are electronic biosensors that can do more or less the same thing. Unfortunately, as was no doubt sometimes the case with the tasters, the biosensors can’t always give us immediate results.
