Bicycle design: back to the drawing board

How a bicycle stays upright while moving has always been something of a mystery to science, with a vague cocktail of gyroscopic effects being the accepted explanation. Now, however, scientists from Cornell University and the Delft University of Technology have determined the complex interplay of design characteristics that make a bike stay upright. The findings, […]

Physics community buzzing over possible new particle

Experiments at Fermilab’s soon-to-be-mothballed Tevatron particle accelerator in the United States have produced collision outcomes that indicate the existence of a new, unknown particle that is not predicted by the fundamental laws of physics. The findings have been posted to Arxiv and have been submitted for publication in the journalPhysical Review Letters. The researchers say […]

Male chromosome facing extinction

It has long been suspected that the sex chromosome that only males carry is deteriorating and could disappear entirely within a few million years, but until now, no one has understood the evolutionary processes that control the Y chromosome’s demise. Now, a pair of Penn State scientists has discovered that the Y chromosome has evolved […]

Biodiversity: It’s In The Water

Hydrology may be more important for predicting biodiversity than biology, say an international group of scientists whose study in the latest issue of Nature challenges current thinking about biodiversity and opens up new avenues for predicting how climate change or human activity may affect biodiversity patterns. Their new method for predicting biodiversity, described by them […]

Toxin Could Be Effective Brain Treatment

University of Utah researchers have found that a nerve toxin used by venomous sea snails can dock with nicotine receptors in the brain, which could lead to new treatments for certain mental illnesses and brain diseases. The study, to be published in the 25 August edition ofThe Journal of Biological Chemistry, was led by J. […]

Understanding More About “Nothing”

Measurements taken using Jefferson Lab’s CEBAF Large Acceptance Spectrometer (CLAS) are telling us more about how matter is produced from “nothing,” that is, the vacuum. Using the CLAS in Hall B, Daniel S. Carman of Ohio University and nearly 150 members of the CLAS Collaboration studied the spin transfer from a polarized electron beam to […]
