Princeton News: A sweet problem: Princeton researchers find that high-fructose corn syrup prompts considerably more weight gain

http://www.princeton.edu/main/news/archive/S26/91/22K07/

High-fructose corn syrup and sucrose are both compounds that contain the simple sugars fructose and glucose, but there at least two clear differences between them. First, sucrose is composed of equal amounts of the two simple sugars -- it is 50 percent fructose and 50 percent glucose -- but the typical high-fructose corn syrup used in this study features a slightly imbalanced ratio, containing 55 percent fructose and 42 percent glucose. Larger sugar molecules called higher saccharides make up the remaining 3 percent of the sweetener. Second, as a result of the manufacturing process for high-fructose corn syrup, the fructose molecules in the sweetener are free and unbound, ready for absorption and utilization. In contrast, every fructose molecule in sucrose that comes from cane sugar or beet sugar is bound to a corresponding glucose molecule and must go through an extra metabolic step before it can be utilized.

...excess fructose is being metabolized to produce fat, while glucose is largely being processed for energy or stored as a carbohydrate, called glycogen, in the liver and muscles.

Document: Toyota warned dealers of throttle surging in 2002

"If you look at this document, it says electronics," Ditlow said. "It says the fix is reprogrammed in the computer. It doesn't say anything about floor mats."

U.N. report: Let's turn foul water from mass killer into global treasure


http://www.cnn.com/2010/HEALTH/03/22/united.nations.water.report/index.html


According to the report -- titled "Sick Water?" -- 90 percent of wastewater discharged daily in developing countries is untreated, contributing to the deaths of some 2.2 million people a year from diarrheal diseases caused by unsafe drinking water and poor hygiene. At least 1.8 million children younger than 5 die every year from water-related diseases, the report says.

"If the world is to thrive, let alone to survive on a planet of 6 billion people heading to over 9 billion by 2050, we need to get collectively smarter and more intelligent about how we manage waste, including wastewaters," said Achim Steiner, U.N. under-secretary general and executive director of UNEP.

"On 2/12/10 my 2010 Toyota Camry received an acceleration fix. In addition I was informed a fail-safe computer program was put in. On 2/17/10 as I was entering my parking slot, the car did an unintended sudden acceleration without my foot being on the accelerator. I was pressing the brake. I jammed both feet into the brake. After 3 seconds, as my car was climbing up a snow bank, it stopped. The engine was idling while my gear shift was in drive. This is the second level on the fail-safe system. This means that: "If both accelerator position sensors fail, or if one throttle position sensor fails, the ECM will...return the engine to idle speed." Had the incident happened one minute earlier, I would have been in a high car/pedestrian area and would not have been able to avoid an accident. The whole event took 5-6 seconds before the car suddenly stopped. The fix done by Toyota is not the fix for the acceleration problem."'

Complaints like these lend credence to reports claiming there might be more to the sudden acceleration issue than bad floor mats and "sticky" gas pedals."
