A neuroscientist at the University of Leicester has recently been awarded major EU funding amounting to €1.7m over four years to investigate how fear and anxiety are formed in the brain, in a project that could lead to more efficient ways of treating stress-related conditions.
Dr Robert Pawlak, a researcher in the University’s Department of Cell Physiology and Pharmacology, has received the prestigious Marie Curie Excellence Grant to support his research project which will look at the mechanisms in the brain that lead to anxiety.
Fear memories are encoded as changes in neuronal connections called synapses, in a process known as plasticity. Dr Pawlak and his colleagues have recently shown that proteases (proteins that cut other proteins) play a critical role in this process and significantly contribute to fear and anxiety related to stress.
Dr Pawlak commented: “Understanding neural bases of stress, fear and anxiety is of immense importance to modern society. The most dramatic form, posttraumatic stress disorder (PTSD) is characterised by cognitive impairment, depression, fear, anxiety, and may eventually lead to suicide.
“Understanding the neural mechanisms of PTSD, depression and anxiety disorders could reduce the personal and societal impact through development of more efficient therapies. This project looks at cellular mechanisms involved in experience-induced neuronal plasticity underlying learning, fear and anxiety.”
Dr Blair Grubb, Head of the Department of Cell Physiology and Pharmacology, added: “EU Marie Curie Excellence Grants are extremely competitive and it is a major achievement that Robert Pawlak has made a successful application so early on in his independent research career.
“Robert is one of a number of neuroscientists working in this department and this grant award adds significantly to our research profile in this general area. The proposed research programme will make a major contribution to our understanding of how stress leads to fear and anxiety.”

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...
