University of California, San Diego neurobiologists have discovered a chemical responsible for the bursts of electrical activity in the brain that guide the development of the visual system, a finding that may bring rewiring of damaged visual circuits closer to reality.
The scientists, who presented their evidence at a session of the annual Society for Neuroscience meeting in San Diego, said their discovery could also lead to a better understanding of birth defects in children born to mothers taking epilepsy medication.
Scientists have long recognized that spontaneous neural activity is needed for the normal development of the visual circuits in the brain, but how this activity is created is not well understood. UCSD researchers Marla Feller and Chih-Tien Wang detailed at the meeting their evidence that the chemical messenger adenosine controls the timing of these bursts of electrical activity. Knowing what triggers these waves of activity could make it possible to recreate them for therapeutic purposes, they said, and may shed light on disorders caused by their disruption.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
