Science and technology news
Acute kidney injury (AKI)—which is often caused by trauma, illness, or surgery—predisposes elderly individuals to the most serious form of chronic kidney disease (CKD), known as end stage renal disease (ESRD), according to a study appearing in the January 2009 issue of the Journal of the American Society Nephrology (JASN). The findings indicate that close medical follow-up is important for maintaining the health of patients who have experienced kidney damage.
Screening for a panel of gene variants associated with the risk for type 2 diabetes can identify adults at risk for the disorder but is not significantly better than assessment based on traditional risk factors such as weight, blood pressure and blood sugar levels. A multi-institutional research team, led by a Massachusetts General Hospital (MGH) physician, reports their analysis of data from the Framingham Heart Study in the November 20 New England Journal of Medicine.
Scientists at the Buck Institute for Age Research have identified for the first time biomarkers of aging which are highly predictive of both chronological and physiological age. Biomarkers are biochemical features that can be used to measure the progress of disease or the effects of treatment.
Testing very young babies for HIV and giving antiretroviral therapy (ART) immediately to those found infected with the virus dramatically prevents illness and death, according to a report in the New England Journal of Medicine. The study found that giving ART to HIV-infected infants beginning at an average age of 7 weeks made them four times less likely to die in the next 48 weeks, compared with postponing ART until signs of illness or a weakened immune system appeared--the standard of care when the study began.
Osteoporosis is a growing concern among breast cancer survivors and their doctors, because certain cancer drugs can cause bone loss.
Modern aircraft have been fabulously successful with rigid wings and rotors. But just imagine the flying machines that would be possible if we could understand and harness the most efficient and acrobatic airfoils in nature: the flexible wings of the bat.
(AP) -- Dr. Adrian Kantrowitz, a cardiac surgeon who performed the nation's first human heart transplant and who also developed lifesaving medical implants, has died. He was 90. Kantrowitz died Friday in Ann Arbor of complications from heart failure, said his wife, Jean Kantrowitz.
Researchers trying to learn whether orcas are starving have turned - with the help of a dog - to a new source of information: orca scat.
You can do it in the air. Or by sea. You can do it if you're young. Or old. Or in 100-plus-degree rooms (Bikram yoga).
Year after year, the number of victims climbed. But even as casualties mounted - as the germ grew stronger and spread inside hospitals - the toll remained hidden from the public, and hospitals ignored simple steps to control the threat.
Scientists have discovered how stress - in the form of emotional, mental or physical tension - physically reshapes the brain and causes long-lasting harm to humans and animals.
As my family looks to control spending, one option is to lower our in-home entertainment costs. We watch a lot of movies. But spending for HBO, Showtime, The Movie Channel and Starz each month really adds to the cable bill and is starting to feel excessive.
It's not "If" your hard drive will fail, it's "When." I've been saying it for years and will continue to do so. Sooner or later something bad will happen and you could lose some or all of your data. So ask yourself right now how bad it would be to lose everything you've worked so hard to create such as your letters, emails, financial data, digital pictures, etc. If it were all to disappear right now, how would you feel? If there's nothing of importance to you on your PC, then you probably just use it to play games and surf the Internet. But for most of us, losing our computer's data could be a total nightmare.
Q. I'm running MS Windows XP Professional with the latest service packs. Whenever I try to open a file on my computer (in MS Word, Adobe Acrobat, or just about anything else), I get an "Open File" dialogue box which by default "Lists" my files.
It has never been easier to get in trouble while catching up with friends. Social networking sites such as Facebook and MySpace are great ways to reconnect with old acquaintances and meet new ones.
Of all the possible ways of reducing future greenhouse gas emissions, one of the most immediately feasible is carbon dioxide "sequestration," which involves compressing the gas into a liquid and piping it deep underground instead of releasing it into the atmosphere. The Earth has abundant geological formations known as saline aquifers that would seem to be ideal storage bins for such sequestered carbon.
(AP) -- D'Zhana Simmons says she felt like a "fake person" for 118 days when she had no heart beating in her chest. "But I know that I really was here," the 14-year-old said, "and I did live without a heart."
(AP) -- It was bad enough when Dan Lyons stopped sharing his musings about the technology scene in a hilarious satire of what Apple Inc. founder Steve Jobs would be like as a blogger.
(AP) -- The astronaut who lost her tool bag on a spacewalk admits she made a mistake and says she should have checked to make sure it was tied down.
