A U physicist will help determine if neutrinos can outrace light

Back in 2007, a physics experiment clocked elusive subatomic particles called neutrinos going faster than light.

That wasn’t supposed to happen. If the speed of light in a vacuum—denoted “c” by physicists—isn’t the universal speed limit, it would mean that Einstein put the wrong number in his famous E=mc² equation.

University of Minnesota physicist Marvin Marshak was part of the experiment, called MINOS. It clocked beams of neutrinos shot from Fermilab, a national physics lab near Chicago, to a detector 457 miles away in the Soudan Underground Laboratory in northern Minnesota. (more…)

How the Brain Makes Memories: Rhythmically!

The brain learns through changes in the strength of its synapses — the connections between neurons — in response to stimuli.

Now, in a discovery that challenges conventional wisdom on the brain mechanisms of learning, UCLA neuro-physicists have found there is an optimal brain “rhythm,” or frequency, for changing synaptic strength. And further, like stations on a radio dial, each synapse is tuned to a different optimal frequency for learning.

The findings, which provide a grand-unified theory of the mechanisms that underlie learning in the brain, may lead to possible new therapies for treating learning disabilities. (more…)

COLUMBIA, Mo. — During the past 60 years, humans have built rockets, walked on the moon and explored the outer reaches of space with probes and telescopes. During these trips in space, research has been conducted to learn more about life and space. Recently, a group of prominent researchers from across the country published a report through the National Academy of Sciences that is intended as a guide as NASA plans the next 10 years of research in space. Rob Duncan, the University of Missouri Vice Chancellor for Research, led the team that developed a blueprint for fundamental physics research in space for the next 10 years. (more…)
