Gas improves blood flow and organ status during minimally invasive sur
As good as laparoscopy is in preventing some of the stresses of open surgery on the body, it does have drawbacks, including reduced blood flow and organ dysfunction. By adding another gas to the carbon dioxide used to inflate the surgical area during laparoscopy, researchers have found they can preserve more normal blood flow during noninvasive surgery. Laparoscopy is a type of surgery in the abdomen done through small incisions. Feb. 24, 1582: Mark the Date
If you want to keep track of history, you'll need a really good calendar. How about this one? Compiled by Tony Long. Scientists Describe How 1918 Influenza Virus Sample Was Exhumed In Ala
In an article in the journal Antiviral Therapy, scientists at NIAID narrate the story of how scientists discovered samples of the 1918 strain in fixed autopsy tissues and in the body of a woman buried in the Alaskan permafrost. The article places this discovery in the context of decades of research into the cause of pandemic influenza, and the authors detail the strange convergence of events that allowed them to recover and sequence the virus in the first place. Microorganisms in toxic groundwater fine-tuned to survive
Microorganisms can indeed live in extreme environments, but the ones that do are highly adapted to survive and little else, according to researchers. Hybrid Molecule Causes Cancer Cells To Self-destruct
By joining a sugar to a short-chain fatty acid compound, Johns Hopkins researchers have developed a two-pronged molecular weapon that kills cancer cells in lab tests. New Findings Lead Researchers To Question Basic Assumptions Of Fisheri
Biologists speaking at a symposium in Washington, D.C., last week warned that fundamental assumptions underlying current fisheries management practices may be wrong, resulting in management decisions that threaten the future supply of fish and the long-term survival of some fish populations. Nanotube Forests Grown On Silicon Chips For Future Computers, Electron
Engineers have shown how to grow forests of tiny cylinders called carbon nanotubes onto the surfaces of computer chips to enhance the flow of heat at a critical point where the chips connect to cooling devices called heat sinks. Harmful Byproducts Of Fossil Fuels Could Be Higher In Urban Areas
Nitrogen oxides, the noxious byproduct of burning fossil fuels that can return to Earth in rain and snow as harmful nitrate, could taint urban water supplies and roadside waterways more than scientists and regulators realize, according to new research in the journal Environmental Science and Technology. Space Station To Grow Faster, Mark Firsts Throughout Year
Already spanning an acre in orbit, the International Space Station this year will grow faster in size, power, volume and mass than ever before, significantly expanding its capabilities and setting new records for humans in orbit. Exposure To Smoking-cessation Product Ads Helps Smokers Quit
The more magazine ads smokers see for the nicotine patch and other quit-smoking aids, the more likely they are to try to quit smoking and be successful --- even without buying the products, finds a new Cornell study. Researchers calculated that if the smoking-cessation product industry increased its average annual spending on magazine advertising by about $2.6 million or 10 percent, the average smoker would see 2.1 more ads each year; according to their calculations, this would translate to about 80,000 additional quits each year.
