Trees are not as sound asleep as you may think

EurekAlert! - Jue, 04/19/2018 - 22:00
High-precision three-dimensional surveying of 21 different species of trees has revealed a yet unknown cycle of subtle canopy movement during the night. The 'sleep cycles' differed from one species to another. Detection of anomalies in overnight movement could become a future diagnostic tool to reveal stress or disease in crops.

HKU medical chemists discover peptic ulcer treatment metallodrug effective in 'taming' superbugs

EurekAlert! - Jue, 04/19/2018 - 22:00
A novel solution to antimicrobial resistance -- HKU medical chemists discover peptic ulcer treatment metallodrug effective in 'taming' superbugs.

How do people die in Switzerland today?

EurekAlert! - Jue, 04/19/2018 - 22:00
Today, almost two thirds of deaths in Switzerland aren't unexpected. How does the cultural context specific to each linguistic region influence end-of-life decisions? Researchers from the universities of Zurich and Geneva noticed significant differences between regions. However, these differences are not always more important than those observed between these regions and the countries with which they share the same language. These results are important to help ground debates on end of life decisions on facts.

A study links soil metals with cancer mortality

EurekAlert! - Jue, 04/19/2018 - 22:00
Spanish epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth's surface on the geographical distribution of tumors should be analyzed.

Treatment of cancer could become possible with adenovirus

EurekAlert! - Jue, 04/19/2018 - 22:00
An international team of researchers led by professor Niklas Arnberg at Umeå University, shows that adenovirus binds to a specific type of carbohydrate that is overexpressed on certain types of cancer cells. The discovery opens up new opportunities for the development of virus-based cancer therapy. The study is published in the latest issue of the scientific journal "Proceedings of the National Academy of Sciences of USA", PNAS PNAS April 19, 2018. 201716900

Lupus treatment generates positive results in Phase III clinical trial

EurekAlert! - Jue, 04/19/2018 - 22:00
New research indicates that belimumab, a monoclonal antibody therapy that targets a component of the immune system, provides considerable benefits to patients with systemic lupus erythematosus (SLE), a predominately female, chronic inflammatory disease that can affect virtually any organ.

Biomarkers for irritable bowel syndrome

EurekAlert! - Jue, 04/19/2018 - 22:00
Little is still known about the exact causes of irritable bowel syndrome. An international team with significant involvement from the Technical University of Munich has provided initial clues about the organic triggers of the disease, which affects an estimated one out of six people.

New DNA screening reveals whose blood the vampire bat is drinking

EurekAlert! - Jue, 04/19/2018 - 22:00
The vampire bat prefers to feed on domestic animals such as cows and pigs. When it does so, there is a risk of transmission of pathogens. Now, a new study describes a new DNA method to efficiently screen many vampire bat blood meal and fecal samples with a high success rate and thereby determine which animals the vampire bats have fed on blood from.

Structured light and nanomaterials open new ways to tailor light at the nanoscale

EurekAlert! - Jue, 04/19/2018 - 22:00
Joint research between Tampere University of Technology, (Finland) and University of Tübingen (Germany) has shown that carefully structured light and matching arrangements of metal nanostructures can be combined to alter the properties of the generated light at the nanometer scale. The teams have shown that the efficiency of nonlinear optical fields generated from the oligomers is strongly influenced by how the constituents of the oligomer constituents are illuminated by structured light.

Russian scientists learned to perform the diagnose by analyzing saliva

EurekAlert! - Jue, 04/19/2018 - 22:00
Researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) within the framework of the Project 5-100 developed a unique method of immune diseases diagnosing before the symptoms appear. Scientists proposed a laser-correlation spectroscopic technique (also called dynamic light scattering) for studying the immune response in body fluids, for example, in saliva.

When there's an audience, people's performance improves

EurekAlert! - Jue, 04/19/2018 - 22:00
Often people think performing in front of others will make them mess up, but a new study found the opposite: being watched makes people do better.

Primary pancreatic organoid tumor models for high-throughput phenotypic drug screening

EurekAlert! - Jue, 04/19/2018 - 22:00
A multidisciplinary team of scientists share recent advancements in innovative in-vitro cancer biology methods for screening drug-like molecules in cancer tissue relevant models in a new report published online ahead-of-print at SLAS Discovery. Entitled Advanced Development of Primary Pancreatic Organoid Tumor Models for High-Throughput Phenotypic Drug Screening, the report can be accessed for free.

One step closer to reality

EurekAlert! - Jue, 04/19/2018 - 22:00
The software 'PyFRAP' is an accurate and reliable tool for the analysis of molecular movement, employing numerical simulations rather than simplified assumptions.

In many countries, bone health may be at risk due to low calcium intake

EurekAlert! - Jue, 04/19/2018 - 22:00
At a special symposium held today at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases in Krakow, Poland, experts discussed the findings of the newly launched IOF Global Map of Dietary Calcium Intake in Adults and the implications of low calcium intake for the global population.

Faster walking heart patients are hospitalized less

EurekAlert! - Jue, 04/19/2018 - 22:00
Faster walking patients with heart disease are hospitalized less, according to research presented today at EuroPrevent 2018, a European Society of Cardiology congress, and published in the European Journal of Preventive Cardiology.

Compound improves stroke outcome by reducing lingering inflammation

EurekAlert! - Jue, 04/19/2018 - 22:00
An experimental compound appears to improve stroke outcome by reducing the destructive inflammation that can continue months after a stroke, scientists report.Rats consuming compound 21 following a clot-based stroke -- the most common type in humans -- don't have a smaller stroke size but do have better memory and movement in its aftermath, says Dr. Adviye Ergul, vascular physiologist and Regents' Professor in the Department of Physiology at the Medical College of Georgia at Augusta University.
