I have been thinking about this too. I don't think Michael Phelps deserves a lot of credit for breaking several world records, he owes these records to technological innovation. Here is an article from Slate explaining the records:
A new record means that an athlete using today's equipment outperformed an athlete using yesterday's equipment. It's not a fair fight.
In swimming alone, today's advantages include:
1. LZR Racer suit. It reduces friction (compared with skin) and is structurally designed to compress and streamline the body for maximum speed. Estimated drag reduction: 5 percent to 10 percent. Estimated average improvement in top swimmers' best times: 2 percent. Designed by NASA scientists and computers, among others. Cost: $500.
2. Pool depth. This is the deepest pool ever used in the Olympics. Depth disperses turbulence, reducing resistance.
3. Pool width and gutters. Two extra lanes at the margins disperse waves to gutters, reducing ricochet and resistance.
4. Lane dividers. The plastic ones in Beijing deflect turbulence down instead of sideways, reducing resistance.
5. Starting blocks. Nonskid versions have replaced the old wooden ones, boosting dive propulsion.
6. Video. Recordings and analysis identify target variables such as stroke distance and turns.
7. Medical tests. Swimmers are blood-tested after each race to measure lactic-acid buildup.
8. Sports scientists. They run the monitoring and analysis. The U.S. swim team has four.
And here's a partial list of advances in other sports:
1. Lighter shoes. The latest material is carbon nanotubes.
2. Asymmetric shoes. Stronger carbon base in the right shoe tilts you to the left to increase speed as you round the track. Left shoe is designed to stabilize you.
3. Ice vest. It lowers your temperature before the race so you can delay overheating for better performance.
4. Hypoxic tents. Sleeping in low-oxygen chambers increases red blood-cell levels.
5. Aluminum javelins. They reduce vibration compared with the old carbon ones.
6. Bicycle wheels. Front wheels with fewer spokes (eight instead of 32) reduce weight and air resistance. So do composite one-piece rear wheels. All frames are carbon.
Michael Phelps' coach says the LZR suit is fair. "Everybody is in the suit so it's across the board," he argues. That may be true of today's top swimmers. But it's not true of yesterday's. So comparing today's performances to the performances of 20, eight, or even four years ago—which is what "new Olympic record" means—is generally unfair.

Cancer Cures Find Biology-Physics Convergence
The engine of growth is innovation and US is the prime location for innovation. This story is from Bloomberg:
Biologists at MIT, in Cambridge, helped discover the genes that have led to a new generation of so-called targeted cancer medicines. MIT -- like Stanford University in California and Emory University in Atlanta -- now is deploying engineers for the first time to build on those successes. The approach is spurring interest from biotechnology company backers, said Terry McGuire, co-founder of Polaris Venture Partners, an investment company in nearby Waltham, Massachusetts.
``Investors are realizing that a combination of engineering and biology is going to yield greater products,'' McGuire said a telephone interview on July 28.
...The U.S. government will spend $4.8 billion on cancer studies in the year ending Sept. 30, almost twice the $2.5 billion a decade earlier, according to the National Cancer Institute in Bethesda, Maryland. About 75 percent of the Koch Institute's $50 million annual science budget comes from federal grants, said the center's director, Tyler Jacks, in a July 15 interview.
MIT biologists were involved in the original gene discoveries that led to the cancer drug Herceptin, made by South San Francisco-based Genentech Inc., and Gleevec, from Novartis AG in Basel, Switzerland. Herceptin, for breast cancer, generated $4.6 billion in revenue, according to Roche Holding AG, the Basel-based drugmaker that also markets the medicine.
The Koch Institute has an even split of biologists and engineers among the 24 faculty members. By comparison, no more than 5 percent of the 28,000 members of the American Association for Cancer Research, based in Philadelphia, specialize in the physical sciences, said Margaret A. Foti, the group's chief executive officer, in a telephone interview.

Two Promising Discoveries
First, 'Major discovery' from MIT primed to unleash solar revolution:
Inspired by the photosynthesis performed by plants, Nocera and Matthew Kanan, a postdoctoral fellow in Nocera's lab, have developed an unprecedented process that will allow the sun's energy to be used to split water into hydrogen and oxygen gases. Later, the oxygen and hydrogen may be recombined inside a fuel cell, creating carbon-free electricity to power your house or your electric car, day or night.
The key component in Nocera and Kanan's new process is a new catalyst that produces oxygen gas from water; another catalyst produces valuable hydrogen gas. The new catalyst consists of cobalt metal, phosphate and an electrode, placed in water. When electricity -- whether from a photovoltaic cell, a wind turbine or any other source -- runs through the electrode, the cobalt and phosphate form a thin film on the electrode, and oxygen gas is produced.
Combined with another catalyst, such as platinum, that can produce hydrogen gas from water, the system can duplicate the water splitting reaction that occurs during photosynthesis.
The new catalyst works at room temperature, in neutral pH water, and it's easy to set up, Nocera said. "That's why I know this is going to work. It's so easy to implement," he said.
Second, Test of Mars Soil Sample Confirms Presence of Ice:
Heated to 32 degrees Fahrenheit, a sample of soil being analyzed by NASA’s Phoenix Mars lander let out a puff of vapor, providing final confirmation that the lander is sitting over a large chunk of ice.
I think we can put a man on Mars in 30 years by generating oxygen and energy using MIT's discovery!!!

L.E.D.
This is from NY Times:
When the Sentry Equipment Corporation in Oconomowoc, Wis., was considering how to light its new factory last year, the company’s president, Michael Farrell, decided to try something new: light emitting diodes, or L.E.D.’s.
“I knew L.E.D.’s were used in stoplights. I wondered why they can’t be used in buildings,” Mr. Farrell said. “So I went on a mission.”
What Mr. Farrell found was a light source that many of the biggest bulb manufacturers are now convinced will supplant incandescent bulbs and compact fluorescent bulbs.
By lighting all of the building’s exterior and most of its interior with L.E.D.’s, Sentry spent $12,000 more than the $6,000 needed to light the facility with a mixture of incandescent and fluorescent bulbs. But using L.E.D.’s, the company is saving $7,000 a year in energy costs, will not need to change a bulb for 20 years and will recoup its additional investment in less than two years.
“I’d do it again,” Mr. Farrell said. “It was a no-brainer.”
L.E.D. bulbs, with their brighter light and longer life, have already replaced standard bulbs in many of the nation’s traffic lights. Indeed, the red, green and yellow signals are — aside from the tiny blinking red light on a DVD player, a cellphone or another electronic device — probably the most familiar application of the technology.
