Molecular culprits of protein aggregation in ALS and FTLD

Jul 18 2018 - 00:07
The mutated and aggregated protein FUS is implicated in two neurodegenerative diseases: amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Using a newly developed fruit fly model, researchers led by prof. Ludo Van Den Bosch (VIB-KU Leuven) have zoomed in on the protein structure of FUS to gain more insight into how it causes neuronal toxicity and disease.

Splitting water: Nanoscale imaging yields key insights

Jul 18 2018 - 00:07
In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel -- just as plants do -- researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. Now scientists at Lawrence Berkeley National Laboratory have pioneered a technique that uses nanoscale imaging to understand how local, nanoscale properties can affect a material's macroscopic performance.

New creepy, crawly search and rescue robot developed at Ben-Gurion U

Jul 18 2018 - 00:07
'The RSTAR is ideal for search and rescue operations in unstructured environments, such as collapsed buildings or flooded areas, where it must adapt and overcome a variety of successive obstacles to reach its target,' says Dr. David Zarrouk, a lecturer in BGU's Department of Mechanical Engineering, and head of the Bio-Inspired and Medical Robotics Lab.

Finding a planet with a 10 years orbit in a few months

Jul 18 2018 - 00:07
To discover the presence of a planet around stars, astronomers wait until it has completed three orbits. However, this effective technique has its drawbacks since it cannot confirm the presence of planets at relatively long periods. To overcome this obstacle, astronomers under the direction of UNIGE have developed a method that makes it possible to ensure the presence of a planet in a few months, even if it takes 10 years to circle its star.

Traditional Tibetan medicine exposes people and environment to high mercury levels

Jul 18 2018 - 00:07
Many people view the Tibetan Plateau, or 'Roof of the World,' as a pristine alpine environment, largely untouched by pollution. But researchers, reporting in ACS' journal Environmental Science & Technology, have now shown that traditional Tibetan medicine exposes people and the environment to high levels of mercury and methylmercury.

Supersharp images from new VLT adaptive optics

Jul 18 2018 - 00:07
ESO's Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography -- and has captured remarkably sharp test images of the planet Neptune and other objects. The MUSE instrument working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope.

NYSCF researchers develop novel bioengineering technique for personalized bone grafts

Jul 18 2018 - 00:07
Scientists from the New York Stem Cell Foundation (NYSCF) Research Institute have developed a new bone engineering technique called Segmental Additive Tissue Engineering (SATE). The technique, described in a paper published online today in Scientific Reports, allows researchers to combine segments of bone engineered from stem cells to create large scale, personalized grafts that will enhance treatment for those suffering from bone disease or injury through regenerative medicine.

Beef jerky and other processed meats associated with manic episodes

Jul 18 2018 - 00:07
An analysis of more than 1,000 people with and without psychiatric disorders has shown that nitrates--chemicals used to cure meats such as beef jerky, salami, hot dogs and other processed meat snacks--may contribute to mania, an abnormal mood state. Mania is characterized by hyperactivity, euphoria and insomnia.

Materials processing tricks enable engineers to create new laser material

Jul 18 2018 - 00:07
By doping alumina crystals with neodymium ions, engineers at the University of California San Diego have developed a new laser material that is capable of emitting ultra-short, high-power pulses -- a combination that could potentially yield smaller, more powerful lasers with superior thermal shock resistance, broad tunability and high-duty cycles.

Quick soil test aims to determine nitrogen need

Jul 18 2018 - 00:07
One of the essential nutrients for vigorous crop production is nitrogen. Yet most routine tests done in commercial soil testing labs do not measure available nitrogen in the soil. Soil scientists at The Ohio State University and Cornell University think they have found a solution.

Fatty liver disease pandemic needs 'gold standard' human-relevant research

Jul 18 2018 - 00:07
New study calls for human-based tools to unravel the pathogenesis of non-alcoholic steatohepatitis (NASH). The contribution of in silico, in vitro and pathways-based systems biology approaches to unraveling the pathogenesis of this disease are described, and how this human-relevant research can be used for anti-NASH drug development.

Study finds high health burdens of very high risk drinking

Jul 18 2018 - 00:07
In an Addiction Biology study, the estimated prevalence of very high risk drinking level (VHRDL, defined as drinking >100 g of ethanol per day) in 13 European Union countries was 0.74-0.85 percent, with a risk of disease or injury of 13.5 per 100 people with VHRDL per year.

Breath tests may allow for earlier detection of pancreatic cancer

Jul 18 2018 - 00:07
Pancreatic cancer carries a very poor prognosis as most patients are diagnosed at an advanced stage. Now a new BJS (British Journal of Surgery) study indicates that breath analyses may help detect pancreatic cancer earlier, when curative treatments may be possible.

Study offers strategies to prevent death by suicide in patients with cancer

Jul 18 2018 - 00:07
In addition to focusing on curing or prolonging the life of patients with cancer, it is important to also address mental health aspects of cancer care, especially because there is an elevated incidence of death by suicide in this patient population. A new Psycho-Oncology analysis uncovers opportunities to mitigate the risk of death by suicide among patients with cancer.
