LOS ANGELES (AP) — Two small planes with three people believed to be aboard collided over the ocean just outside the port of Los Angeles, prompting a massive search by dozens of boats and divers. There was no sign of survivors after hours of searching.
The collision occurred about 3:30 p.m. Friday on a dazzlingly sunny day, the Coast Guard said, with no immediate word on what might have caused it.
Two men ages 61 and 81 were aboard one plane, and a 72-year-old woman was aboard the other plane, Coast Guard Capt. Jennifer Williams said.
As long as you are able to maintain your medical certificate, and pass your biennial flight review, you are legal. Certain very light aircraft are flown on an LSA, wherein your drivers license serves as your medical, and gliders and certain ultra-lights are self certified.I read this news on MSN and wonder if pilot license for a woman at 72 year old is still valid?
A group at Tampa FL, is also invoking evolution for cancer treatment.This, however, does not change the fact that, in order for any mutant to become dominant, the dominating species must extinct. This is still the foundation of evolution. No livin things can slowly mutate to gain or lose certain physiological features.

This is a very interesting study. Treatment resistance has been one of the biggest hurdles in cancer treatments. Many patients develop resistance to treatment, indeed a classic case of tumor cells evolving to develop resistance. By maintaining the dominating treatment-sensitive tumor cells, this strategy effectively keeps resistant cells at bay using the dominating tumor cells to kill off resistant cell. Brilliant! A nice use and demonstration of evolution theories. Nice find!Thanks for your reply. For example, the confidence level of randomness in quantum fluctuations is beyond 5 SD, as inferred from numerous measurements verifying the Standard Model in particle physics. I am just wondering how bullet-proof the concept of randomness is, as applied to mutations and evolution, when the physical origins of this approximation seem to be unspecified and almost taken as default. Are the underlying mechanics, adiabatic, entropic, quantum,....... and thoroughly verified?

"Conventional cancer treatment strategies assume that maximum patient benefit is achieved through maximum killing of tumor cells. However, by eliminating the therapy-sensitive population, this strategy accelerates emergence of resistant clones that proliferate unopposed by competitors—an evolutionary phenomenon termed “competitive release.” We present an evolution-guided treatment strategy designed to maintain a stable population of chemosensitive cells that limit proliferation of resistant clones by exploiting the fitness cost of the resistant phenotype"
