Trading hour extension effective April 3, 2005/ Nandapurkar: Eurex US offers trading during core business hours in all time zones
Eurex US, the fully electronic U.S. futures and options exchange, announced on Monday that it will be extending its trading day by two hours, from 21 hours to 23 hours, effective April 3, 2005. As of that date trading will begin at 5:00 p.m. Chicago time instead of 7:00 p.m.; the trading day will continue to end at 4:00 p.m. Chicago time on the next cal
Physical traits, genetic test help with early diagnosis
A research team led by Johns Hopkins doctors has defined the physical traits and genetic basis of a new aortic aneurysm syndrome that is extremely aggressive and can cause death in early childhood. Early diagnosis of the syndrome and rapid surgical repair of the swollen aorta can save lives, the researchers report in the Jan. 30 advance online section of Nature Genetics.
Based on a review of medical records and exp
More Britons are living alone than ever before, with more men than women living on their own between the ages of 25 and 44. And once someone has gone solo, they are more likely to remain living alone shows new research funded by the Economic and Social Research Council (ESRC).
Using census statistics and data tracking the lives of more than 150,000 individuals in England and Wales since 1971, researchers led by Malcolm Williams, of the University of Plymouth, found a significan
After years of trial and error, scientists have coaxed human embryonic stem cells to become spinal motor neurons, critical nervous system pathways that relay messages from the brain to the rest of the body.
The new findings, reported online today (Jan. 30, 2005) in the journal Nature Biotechnology by scientists from the University of Wisconsin-Madison, are important because they provide critical guideposts for scientists trying to repair damaged or diseased nervous systems.
Just fifteen minutes of training could make it possible for anyone to use a defibrillator to stop sudden cardiac arrest. A study published today in the journal Critical Care shows that a brief training session is all that is needed for safe and efficient use of an automated external defibrillator.
Sudden cardiac deaths affect nearly 400,000 people per year in Europe, and every day in the U.S. more than 1,200 people die from cardiac arrest before they reach hospital. In most cas
New Boston College/UMass study analyzes student computer use and test performance
Regular use of computers can have an effect on student performance on standardized tests, according to a new study by researchers at Boston College and the University of Massachusetts at Lowell.
Analyzing test performance and computer uses of 986 fourth grade students from 55 classrooms in nine Massachusetts school districts, the study found that the more regularly students use computers t
Contrary to the results of a recent U.S. study, investigators in Japan found no association between a herpesvirus infection and a potentially life-threatening form of high blood pressure, as reported in the March 1 issue of The Journal of Infectious Diseases, now available online.
The researchers reported that they were not able to detect human herpesvirus 8 (HHV-8), also known as the Kaposi’s sarcoma virus, in the lungs of 22 patients with primary or other forms of pulmonary hy
Winter is here, snow is falling in many areas of the country, and some of us are already wishing for the return of hot summer days. But, would you believe that even on the hottest summer day the temperature inside some clouds remains icy and winter-like, producing temperature readings as cold as negative 70 degrees Celsius (negative 94 degrees Fahrenheit)? Would you also believe that the ice crystals that form at the top of big summertime clouds may help scientists predict next winter’s

Hear the synchronized vibrations from a chorus of more than 4,000 nano-whistles, created when physicists pushed superfluid helium-4 though an array of nanometer-sized holes. Note that the pitch drops as the pressure drops.

An international team of scientists embarked this week on a journey to improve modeling of global-scale air quality and climate change predictions by conducting high quality measurements of the Arctic region’s atmosphere.
The Polar Aura Validation Experiment (PAVE) will gather information to validate data from NASA’s Aura satellite, launched in July 2004. PAVE is the third in a series of planned Aura validation and science missions. These missions will help understand the trans

In a Policy Forum article forthcoming in the January 28 issue of the journal Science, Arizona State University marine biologist Leah Gerber, Duke University marine biologist K. David Hyrenbach, and University of Victoria geographer Mark Zacharias argue that the current san
As the human genome sequence neared completion several years ago, geneticists eagerly began discussing which other organisms to sequence — partly to see which DNA regions are similar across species and therefore likely to serve critical functions. But these discussions raised an important, and potentially expensive, question: How many species need to be sequenced to know whether evolution has conserved a given stretch of DNA?
In an article published in the January 2005 issue of PL
In the most detailed large-scale study to date of the proteins that package DNA, researchers have mapped a family of switches that turn genes on and off. Their findings may help scientists understand regulatory mechanisms underlying cancer and human development.
The research team includes first author Bradley Bernstein, recipient of a Howard Hughes Medical Institute (HHMI) physician postdoctoral fellowship who works in the Harvard University laboratory of HHMI investigator Stua
Study of a Completely New Way of Trying to Treat Cancer in the Future by the Use of Vaccination Injections
The first U.S. kidney cancer vaccine trial is now underway at Columbia University Medical Center and NewYork-Presbyterian Hospital/Columbia. While the potential for vaccines to treat solid tumors has been recognized for more than a decade, this trial is pioneering the use of tumor immunotherapy – boosting the body’s natural immune system – as a way to fight cancer.

One in five mammals living on Earth is a bat, yet their evolutionary history is largely unknown because of a limited fossil record and conflicting or incomplete theories about their origins and divergence. Now, a research team including University of California, Riverside Biology Professor Mark Springer, has published a paper in the Jan. 28 issue of the journal Science that uses molecular biology and
