Using a novel imaging system for quantifying aspects of cell division in three dimensions, scientists have discovered new interactions between sister kinetochores -- the protein bundles at the contact point between the two identical strands of a chromosome -- and the microtubule motors that help pull the strands apart.
ATV and motocross sports: High velocity toys merit caution, experts say

Over the years, all terrain vehicles (ATVs) and motocross motorcycles have gained popularity and marketed as toys to consumers. These high-velocity machines can weigh between 300 and 600 pounds, and run on average between 25 and 60 miles per hour, while some even reach maximum speeds of 75 miles per hour. In 2008, nearly 28 percent of all ATV-related injuries were to children younger than 16. There were an estimated 135,000 injuries for riders of all ages for ATV use. A majority of ATV injuries happen from tipping, overturning or multiple riders.
Playing music on your clothing

In the future it may be considerably easier for orchestras to tour. Jeannine Han, who is in the second year of her master's program in textiles and fashion design at the Swedish School of Textiles in Borås, Sweden, working together with technician Dan Riley, has developed clothing that plays music when touched.
Physicists take atoms for a quantum walk

A team of physicists has achieved a quantum walk in a quantum system with up to 23 steps. It is the first time that this quantum process using trapped ions has been demonstrated in detail. This latest advance promises to be important for the development of quantum computers in finding search quantum algorithms that outperform their classical counterparts as different directions could be chosen simultaneously.
Designer nano luggage to carry drugs to diseased cells

Scientists have succeeded in growing empty particles derived from a plant virus and have made them carry useful chemicals. The external surface of these nano containers could be decorated with molecules that guide them to where they are needed in the body, before the chemical load is discharged to exert its effect on diseased cells. The containers are particles of the Cowpea mosaic virus, which is ideally suited for designing biomaterial at the nanoscale.
'The Rosenfeld' named after California's godfather of energy efficiency

Pioneering French physicists Marie and Pierre Curie have the curie, a unit of radioactivity, named after them. Renowned inventor Nikola Tesla is honored with the tesla, which measures a magnetic field. And now, the Rosenfeld, proposed as a unit for electricity savings, will be named after the man seen by many people as the godfather of energy efficiency, Arthur Rosenfeld.

Let us think of education as the means of developing our greatest abilities, because in each of us there is a private hope and dream which, fulfilled, can be translated into benefit for everyone and greater strength for our nation.
The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of suc
