## High Fructose Corn Syrup To Get a Makeover646646

An anonymous reader writes "With its sweetener linked to obesity, some cancers and diabetes, the Corn Refiners Association (CRA) doesn't want you to think 'fructose' when you see high fructose corn syrup in your soda, ketchup or pickles. Instead, the AP reports, the CRA submitted an application to the FDA, hoping to change the name of their top-selling product to 'corn sugar.'"

It is completely impractical to compare this with a space shuttle re-entering. The mass difference alone makes it a completely different problem. Also a space shuttle burns tons and tons of rocket fuel in exchange for altitude and velocity. This requires a lot of energy - energy that when it needs to return to Earth the space shuttle needs to get rid off, it does this by converting it to heat. For this project, a balloon is being used to provide the lift. This gives it the potential energy of height, but not the velocity needed to retain orbit. Once you take away the lift- you return to Earth. Coupled with the massive weight difference means there is no where near as much energy that must be converted into heat. A skydiver reaches terminal velocity as a result of their mass and surface area presented to the relative wind. Terminal velocity also depends on air density - altitude and temperature. So a skydiver can go faster by increasing their mass, reducing the cross-sectional area presented to the relative wind or jump from higher altitudes (or on warmer days). In fact even from an altitude of 13,000ft a skydiver will reach terminal velocity after 1000ft and then gradually slow down as the air density increases. Felix will be seeing this on a much grander scale - less air, higher terminal velocity but less friction. Also the speed of sound is slower at higher altitudes because the air is thinner. Some sources actually credit Joseph Kittinger with breaking the speed of sound at his altitude. There are various problems that must be solved for this to succeed, but I think its entirely possible and I am looking forward to seeing him pull it off.

## NVIDIA Shows Off "Optimus" Switchable Graphics For Notebooks102102

Vigile writes "Transformers jokes aside, NVIDIA's newest technology offering hopes to radically change the way notebook computers are built and how customers use them. The promise of both extended battery life and high performance mobile computing has seemed like a pipe dream, and even the most recent updates to 'switchable graphics' left much to be desired in terms of the user experience. Having both an integrated and discrete graphics chip in your notebook does little good if you never switch between the two. Optimus allows the system to seamlessly and instantly change between IGP and discrete NVIDIA GPUs based on the task being run, including games, GPU encoding or Flash video playback. Using new software and hardware technology, notebooks using Optimus can power on and pass control to the GPU in a matter of 300ms and power both the GPU and PCIe lanes completely off when not in use. This can be done without being forced to reboot or even close out your applications, making it a hands-free solution for the customer."

## Comment This isn't gliding (Score 1)140140

Flying 23km's after exiting from 6,500ft is far from gliding. A skydiver typically deploys their parachute between 3000ft and 4000ft and often higher in technical jumps such as this. This means he must maintain an almost flat glide angle, thus requiring thrust making it a powered flight, not a glider. Wingsuiters have flown these sort of distance but they exited from around 23,500ft and utilised tail winds.

I have personally seen interference between aircraft controls and a wireless mouse! Whenever a colleague flew his remote control helicopter it would prevent another persons wireless mouse from working. So it seems perfectly plausible that a wireless mouse could affect a jet!
