What If" How a Man Survived Without Food For Two Months in a Snow-Buried Car. Dropping a Magnet Through a Copper Pipe. Turning The iPhone Into A 350x Medical Microscope For Under $50. Using the iPhone (or any mobile smartphone or tablet device, really) for medical purposes isn’t a new thing, but it’s nice to see the applications people cook up.
Just recently at Disrupt we saw Smartheart, and apps like Skin Scan are decentralizing some simple self-monitoring tasks like melanoma detection. We’ve also seen lots of physical additions to the iPhone camera. Stem-cell medicine: Hope over hype. Origin of life: enzyme-free copying of RNA. Organisms today employ multiple enzymes, proteins and RNA, to catalyze biochemical reactions that are essential for life.
According to the RNA world model, DNA and proteins were absent when life originated. Life began with RNA, which passed on genetic information and catalyzed biochemical reactions. In order for RNA to pass on genetic information, it must be able to copy itself and produce a complementary sequence of RNA. A few months ago, we covered a RNA enzyme that can replicate RNA sequences that are long enough to have biochemical functions. In a recent issue of Nature Chemistry, chemists propose an explanation for the step between the formation of random, short RNA sequences and that of relatively large, catalytically active RNA enzymes.

Louann Brizendine of the University of California in San Francisco and author of "The Female Brain. " Despite the trumpets of women's lib, science suggests sex differences are innate. Women, apparently, are not curvy versions of men sporting high-heeled shoes. Here are 10 things every woman-loving man should know. Author Bio. Game of Nim. Douglas Engelbart. In the early 1950s, he decided that instead of "having a steady job" (such as his position at NASA's Ames Research Center) he would focus on making the world a better place, especially through the use of computers. Engelbart was therefore a committed, vocal proponent of the development and use of computers and computer networks to help cope with the world’s increasingly urgent and complex problems.
Engelbart embedded a set of organizing principles in his lab, which he termed "bootstrapping strategy". He designed the strategy to accelerate the rate of innovation of his lab. In 1988, Engelbart and his daughter Christina launched the Bootstrap Institute (later known as The Doug Engelbart Institute) to promote his vision, especially at Stanford University; this effort did result in some DARPA funding to modernize the user interface of Augment.

Fleeting antimatter trapped for a quarter of an hour - physics-math - 03 May 2011.
By Mark Buchanan Update: This work has now been published in the journal Nature Physics (DOI: 10.1038/nphys2025) What can you do with a quarter of an hour?
Write a few emails, cook rice – or store antimatter. The team working on the Antihydrogen Laser Physics Apparatus (ALPHA) at the CERN particle physics laboratory near Geneva, Switzerland, have stored atoms of antihydrogen for 1000 seconds – roughly 10,000 times longer than before. A Virus That Could Help You Lose Weight. Laser stops spreading cancer cells in their tracks - health - 11 February 2011. Tumour-zapping lasers are being deployed on another front of the war against cancer.
A new study shows they can help to stop a cancer from spreading by destroying the lymphatic vessels that act as highways for the mutant cells. In Photodynamic therapy, or PDT, doctors inject a light-sensitive drug into tumours near the skin's surface and then turn an infrared laser on it. The light encourages the drug to produce a form of oxygen that destroys cancer cells.
The therapy is already used to precisely target several types of cancer tumour. But by using it on nearby vessels instead, Tuomas Tammela and his colleagues at the University of Helsinki in Finland think that PDT might help to stop cancer spread in its tracks. Cancer spread, or metastasis, occurs when tumour cells enter lymph or blood vessels. Lighting lymph To halt cancer spread through the lymphatic system, Tammela's team simply destroyed the lymphatic vessels near the tumour. Doc Gernez et le cancer - Voir le sujet. Homepage. The Next Wave Of Smart Drugs. Top 10 Inventions by African-Americans" Sarah Breedlove was born in 1867.
She was an orphan at age 8, a wife at 14, a mother at 17 and a widow at 19. Breedlove supported her family for 18 years as a laundress, but in the early 1900s, she reinvented herself as Madam C.J. Walker, creator of the Walker Hair Care System. Breedlove had suffered extreme hair loss, which was common for black women of the time, due to scalp disease, bad diet, damaging hair products and infrequent washing.
