A Florida State University research team in Tallahassee, Fla. reports that it has designed a biomedical device that will allow stem cells derived from adult bone marrow to be grown in sufficient quantities to permit far more research -- and allow faster growth of tissues that can be transplanted into patients. Penn Researchers Warn Against Potential Flaws In Wiretapping Technolog
As part of a federally funded program on electronic security, engineers at the University of Pennsylvania have discovered flaws in wiretapping technology that could allow parties being wiretapped to disable the recording and monitoring of their calls. The Penn researchers' findings will enable law-enforcement agencies to detect and compensate for the flaws. New Clues Add 40,000 Years To Age Of Human Species
Nearly 40 years after an historic anthropology expedition to Ethiopia's Lake Turkana basin, researchers have uncovered evidence suggesting human bones found at that time are roughly 195,000 years old. The researchers believe the findings may bolster the "Out-of-Africa"hypothesis that suggests we all trace to an ancient line that first evolved in Africa and then displaced other hominids as recently as 50,000 years ago. NIST Unveils Atom-based Standards For Measuring Chip Features Under 5
Device features on computer chips as small as 40 nanometers (nm) wide--less than one-thousandth the width of a human hair--can now be measured reliably thanks to new test structures developed by a team of physicists, engineers, and statisticians at the Commerce Department's National Institute of Standards and Technology (NIST), SEMATECH, and other collaborators. Tracking The Elusive Shipping Container
The world is a different place out beyond the horizon, where thousands of cargo ships ply the world's oceans, pulling into ports, loading, unloading, changing crews and cargos. It can be an amazingly trackless story. How do these ships come by and load their cargos, by what polyglot seamen, and in what untamed ports? Along the journey, pry open a container and what will you find? If you're not sure, that spells danger. New Study Gets At Heart Of Stroke Risk
Now it appears a blood pressure-lowering regimen that includes drugs known as calcium antagonists is comparable to traditional therapy with beta-blockers and diuretics when it comes to warding off stroke in patients with heart disease, University of Florida researchers reported today (March 8) at the annual scientific sessions of the American College of Cardiology. Source Of Fever Identified
With the finding that fever is produced by the action of a hormone on a specific site in the brain, scientists have answered a key question as to how this adaptive function helps to protect the body during bacterial infection and other types of illness. Research Finds Cigarette Manufacturers Target Youth Market With Candy
New research from the Harvard School of Public Health finds that cigarette makers are targeting young smokers with candy and liqueur-flavored new brands that mask the harsh and toxic properties found in tobacco smoke, and in one case, embedding a hidden flavor pellet within the filter. Acrylamide Not Linked To Breast Cancer, Study Finds
Foods that contain acrylamide are unlikely to cause breast cancer in women, according to preliminary results of a new study involving 100,000 US women. The finding is the largest epidemiological study to date exploring the possible link between acrylamide and cancer in humans.
