Rockefeller scientists show that microRNAs play an essential role in the development of the fruit fly
In a story reminiscent of David and Goliath, new research from Rockefeller University shows that sometimes the smallest molecules can be the most powerful. In the July 1 issue of Cell, Ulrike Gaul, Ph.D., and colleagues report that microRNAs serve very important, and very specific, functions during the early development of the fruit fly.
First discovered a few years ago, microRNAs are short strings of RNA that are made in large amounts in every cell from plant to humans. Biochemists, including co-author Thomas Tuschl, Ph.D., found that microRNAs bind to messenger RNAs, which are the blueprints for proteins, and either target them for destruction or inhibit them from making proteins. "There was a lot of beautiful biochemistry showing how microRNAs are made and processed," says Gaul, head of the Laboratory for Developmental Neurogenetics. "But we didn’t really know how important they are for the development of an organism and its function."

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
