We Need a Better Yardstick to Measure Digital Divide

September 30, 2006 8:00 pm | News | Comments

Relying on easy-to-measure factors like how many Internet access points a place has presents a simplistic picture of today's digital divide. A more sophisticated approach is needed to get an honest assessment of who is being left behind…

Planet Earth May Have 'Tilted' to Keep its Balance

August 31, 2006 8:00 pm | News | Comments

Imagine a shift in the Earth so profound that it could force our entire planet to spin on its side after a few million years, tilting it so far that Alaska would sit at the equator. Princeton scientists have now provided the first compelling evidence…

Will Take a Little Time

August 31, 2006 8:00 pm | by Bill Weaver, Ph.D. | Articles | Comments

New chip-scale atomic clocks Bill Weaver, Ph.D. Historians continue to wrestle over an exact date for the start of the Industrial Revolution. Generally placed in the late 1700s, it is often correlated with the widespread use of the steam engine and coal as an energy source. As a technophile, I like to attribute it the invention of tools having an intrinsic awareness of time. Hammers, chisels and saws have been in use for centuries, and...

Integrative Computational Biology: A strategy for the 21st Century

August 31, 2006 8:00 pm | by John A. Wass, Ph.D. | Articles | Comments

During routine perusal of the literature for mathematically oriented materials on biological problems, I found one of the more interesting examples I’ve seen in my daily mail. It was titled “A Strategy for Integrative Computational Physiology,” and contained a game plan for developing a quantitative modeling framework for dealing with what the authors called multiscale issues.

The Power and Pain of Analog Synthesis

August 31, 2006 8:00 pm | by Sanjivanjit K. Bhal, Ph.D., and Greg M. Pearl, Ph.D. | Articles | Comments

Extending physicochemical property prediction to medicinal chemistry Sanjivanjit K. Bhal, Ph.D. and Greg M. Pearl, Ph.D. Analog synthesis lies at the heart of the drug discovery process, and can help to improve the final product while limiting business risks. Pioneering drugs are often followed by analogs from competitors (‘me too’ drugs) and follow-on drugs that address limitations of the original therapeutic. For example, the recognized...

MEMS Technology Helps Redefine Traditional Chemical Analysis Methods

August 31, 2006 8:00 pm | by Mouli Ramani | Articles | Comments

Micro-electro-mechanical systems expand the role of near-infrared Mouli Ramani For many years, near-infrared (NIR) was considered to be an experimental curiosity relative to its role and application for chemical analysis. Early UV-visible instruments provided the option of an extended range that designated the near-infrared as the shortwave region from 700 to 1100 nm. Information from this region was limited to the measurement of key parameters...

A novel visualization tool for spectroscopic and metabolomics study Omoshile Clement, Ph.D., Ty Abshear, Gregory M. Banik, Ph.D., and Chen Peng, Ph.D. Spectroscopists typically generate large amounts of spectral and chromatographic data from various analytical instruments. These data require an efficient data mining and analysis process in order to sieve the requisite information from the datasets. In many cases, it is necessary to display...

Ethernet Advances Allow Intensive Applications to Reap Full Benefits

August 31, 2006 8:00 pm | by Uri Cummings, Ph.D. | Articles | Comments

Convergence of 10-gigabit Ethernet with low latency technologies is reducing latency and improving efficiency Uri Cummings, Ph.D. In June of this year, the TOP500 organization once again released its biannual report on the top 500 supercomputers in the world. These new rankings mark the first time in history that gigabit Ethernet is the message-passing interconnect (MPI) for the majority of HPC clusters on the list. In fact, from the November...

Not Everything Slimy is an Amphibian

August 31, 2006 8:00 pm | by Randy C. Hice | Blogs | Comments

Spammers are on notice Randy C. Hice It all started as an epic power play in the first grade. My son Colin had prevailed through shrewd bargaining, fast talking, and not a small amount of politicking. So, one day, he brought home Frogsey, a small aquarium habitat, and a shaker of dried bloodworms. Frogsey’s digs are right next to the coffee maker, and I always make a racket when I fire the thing up to grind and brew my home-roasted beans. The first...
