A bold paper which has highly impressed some of the world´s top physicists and been published in the August issue of Foundations of Physics Letters, seems set to change the way we think about the nature of time and its relationship to motion and classical and quantum mechanics. Much to the science world´s astonishment, the work also appears to provide solutions to Zeno of Elea´s famous motion paradoxes, almost 2500 years after they were originally conceived by the ancient Greek philosopher.

Since the time when humans first learned to record their thoughts in written form, codes have kept sensitive information from prying eyes. But conveying information through a code requires someone who can read it as well as write it. The same is true for one of nature´s methods for transmitting information that activates or silences a gene: the “histone code.”

First formally proposed in 2000 by C. David Allis, Ph.D., and his postdoctoral fellow Brian Strahl, Ph.D., the histone code is

Scientists have inactivated almost three-quarters of all genes in the genome of Arabidopsis thaliana, a species widely used in plant research. The feat, which results in the largest so-called “knockout” gene collection of a complex multi-cellular organism, now allows researchers to study the function of each of those genes individually or together.

The findings, published in the August 1 issue of the journal Science, mark an important milestone in the field of plant genomics. Follow

Finding will aid drug design to combat depression, stroke and diabetes. Scientists are a step closer to understanding how essential nutrients, vitamins and minerals are ferried into cells.

For the first time, a member of the Major Facilitator Superfamily (MFS) of transport proteins, found in almost every form of life, has been visualised by researchers from Imperial College London and the University of California, Los Angeles.

Reporting in Science today, the researchers reve

A signal that triggers half the stem cells in the developing brain to commit suicide at a stage where their survival will likely do more harm than good has been identified by researchers at the Medical College of Georgia and the University of Georgia.

Identifying the factors that result in the timely, massive cell suicide is important to understanding the developmental puzzle, the researchers say of the work featured on the cover of the Aug. 4 issue of the Journal of Cell Biology.

Swift or safe? That may be the question drivers with navigation systems ask themselves in future.

A new study by researchers at the University of Toronto Intelligent Transportation Systems (ITS) Centre and Testbed suggests in-car systems, designed to guide drivers around traffic jams and accidents quickly, could actually cause a temporary surge in the risk of accidents. “Discovering that traveller information systems may be good for travel time but not for overall safety was shocking
