If the world’s human population continues to rise at its current rate, the planet will increase the numbers of threatened species at least 7 percent worldwide in the next 20 years and twice that many by the year 2050.
In a recent model of the impact human population growth has on biological diversity, Ohio State University anthropologist Jeffrey McKee and his colleagues warn that the United States alone will add at least 10 additional species to the “threatened” list within 50 years.
Whether food-borne bacteria make people sick depends on a variety of factors, and better understanding of the infection process could lead to ways to stop such illnesses from occurring, according to Purdue University scientists.
In the first comprehensive study of the virulence of Listeria monocytogenes, researchers report that how well the bacteria attach to cells does not alone determine the degree of illness. The factors that determine if a person becomes ill and the degree of illness in
Scientists working with cells that may someday be used to replace diseased or damaged cells in the brain have taken neural stem cell technology a key step closer to the clinic.
Writing in the current online edition (June 2003) of the Journal of Neurochemistry, scientists from the University of Wisconsin-Madison’s Waisman Center describe the first molecular profile for human fetal neural stem cell lines that have been coaxed to thrive in culture for more than a year.
The work is a
Joint news release of Infineon Technologies and IBM
IBM and Infineon Technologies AG (FSE/NYSE: IFX) today announced they have developed the most advanced Magnetic Random Access Memory (MRAM) technology to date by integrating magnetic memory components into a high-performance logic base.
Today’s announcement could accelerate the commercialization of MRAM, a breakthrough memory technology with the potential to begin replacing some of today’s memory technologies as early as
Researchers have identified a mechanism by which the eight amino acid peptide NAP, an active fragment of a neuroprotective brain protein, protects against alcohol-induced embryo toxicity and growth retardation in mice. Their findings bring alcohol researchers a critical step closer to developing pharmacologic agents to prevent alcohol-induced fetal damage. The study, funded by the National Institutes of Healths National Institute on Alcohol Abuse and Alcoholism (NIAAA), the National Institute o
Cells show promise for cancer and transplant patients because of rapid growth in bone marrow
Scientists with University Health Network have discovered a new class of human stem cells that rapidly grow when implanted in the bone marrow of mice. The findings, available today in an advance on-line publication of the international scientific journal Nature Medicine, are a major advancement in human stem cell research with possible significant clinical implications for designing more effec
