TROY, N.Y. -- In a money-saving revelation for organizations inclined to invest in specialized information technology to support the process of idea generation, new research suggests that even non-specialized, everyday organizational IT can encourage employees' creativity. Recently published in the journal Information and Organization, these findings from Dorit Nevo, an associate professor in the Lally School of Management at Rensselaer Polytechnic Institute, show standard IT can be used for innovation. Furthermore, this is much more likely to happen when the technology is in the hands of employees who are motivated to master technology, understand their role in the organization, ...

In a study to examine a Mediterranean diet in relation to prostate cancer progression in men on active surveillance, researchers from The University of Texas MD Anderson Cancer Center found that men with localized prostate cancer who reported a baseline dietary pattern that more closely follows the key principles of a Mediterranean-style diet fared better over the course of their disease. "Men with prostate cancer are motivated to find a way to impact the advancement of their disease and improve their quality of life," said Justin Gregg, M.D., assistant professor of Urology and lead author of the study, published today in Cancer. ...

Tsukuba, Japan - Does losing weight while you sleep sound too good to be true? According to a study by the University of Tsukuba, it seems that drinking oolong tea might help you do just that. While all tea comes from the same plant, Camellia sinensis, the degree of oxidation, a chemical reaction that turns tea leaves black, defines its specific type. For example, green tea is unoxidized and mild in flavor, while the distinctive color of black tea comes from complete oxidation. Oolong tea, being only partially oxidized, lies somewhere in between and displays characteristics ...

Some people have lost their eyesight, but they continue to "see." This phenomenon, a kind of vivid visual hallucination, is named after the Swiss doctor, Charles Bonnet, who described in 1769 how his completely blind grandfather experienced vivid, detailed visions of people, animals and objects. Charles Bonnet syndrome, which appears in those who have lost their eyesight, was investigated in a study led by scientists at the Weizmann Institute of Science. The findings, published today in Brain, suggest a mechanism by which normal, spontaneous activity in the visual centers of the brain can trigger visual hallucinations in the blind. Prof. Rafi Malach and his group members of the Institute's Neurobiology Department research the phenomenon of spontaneous "resting-state" ...

Research from life-saving charity Air Ambulance Kent Surrey Sussex (KSS) in partnership with the University of Surrey has shown the benefits of dispatching HEMS to patients with a sudden, unexplained LOC of medical origin and a high prevalence of acute neurological pathology. The study - which is believed to be the first published about HEMS dispatch to non-trauma (neuro) cases - also highlights how HEMS dispatchers in dialogue with ambulance personnel are able to select patients requiring HEMS-specific interventions and, based on its findings, identifies opportunities to improve triage for these patients. Through a retrospective study of all patients with a LOC ...

In a study spanning four decades, researchers from the University of Hong Kong's Research Division for Ecology & Biodiversity (HKU) in the Faculty of Science, and Toho University's Department of Biology (Toho), Japan, have discovered that predation by snakes is pushing lizards to be active at warmer body temperatures on islands where snakes are present, in comparison to islands free from snakes. Their work also detected significant climatic warming throughout the years and found lizard body temperatures to have also increased accordingly. The findings show that lizard thermal biology is highly dependent on predation pressures ...

Geneva, Switzerland, 7 January 2021 - 'Mini-brains' are pin-head sized collections of several different types of human brain cell. They are used as a tool, allowing scientists to learn about how the brain develops, study disease and test new medicines. Personalized 'mini-brains' can be grown from stem cells generated from a sample of human hair or skin and could shed light on how brain disease progresses in an individual and how this person may respond to drugs. Research published today by a team of scientists and engineers from HEPIA and the Wyss Center for Bio and Neuroengineering, in the journal Frontiers in Bioengineering and Biotechnology, has revealed ...

Until now, the reason why the drug levodopa (L-Dopa), which reduces the motor symptoms of Parkinson's disease, declines in efficacy after a few years' use has been unknown. A side effect that then often occur is involuntary movements. A Swedish-French collaboration, led from Uppsala University, has now been able to connect the problems with defective metabolism of L-Dopa in the brain. The study is published in Science Advances. "The findings may lead to new strategies for treating advanced Parkinson's," says Professor Per Andrén of the Department of Pharmaceutical Biosciences at Uppsala University. He and Dr Erwan Bézard of the University of Bordeaux, France, headed ...

The coastline of Israel is one of the warmest areas in the Mediterranean Sea. Here, most marine species have been at the limits of their tolerance to high temperatures for a long time - and now they are already beyond those limits. Global warming has led to an increase in sea temperatures beyond those temperatures that Mediterranean species can sustain. Consequently, many of them are going locally extinct. Paolo Albano's team quantified this local extinction for marine molluscs, an invertebrate group encompassing snails, clams and mussels. They thoroughly surveyed the Israeli coastline and ...

Sweden kept preschools, primary and lower secondary schools open during the spring of 2020. So far, little research has been done on the risk of children being seriously affected by COVID-19 when the schools were open. A study from Karolinska Institutet in Sweden has now shown that one child in 130,000 was treated in an intensive care unit on account of COVID-19 during March-June. The study has been published in New England Journal of Medicine. So far, more than 80 million people have become ill with COVID-19 and globally, almost two million people have died from the disease. Many countries have closed down parts of society in order to reduce the spread of infection. One such measure has been to close schools. ...

Men and women aged over 50 can reap similar relative benefits from resistance training, a new study led by UNSW Sydney shows. While men are likely to gain more absolute muscle size, the gains relative to body size are on par to women's. The findings, recently published in END ...

Social media misinformation can negatively influence people's attitudes about vaccine safety and effectiveness, but credible organizations -- such as research universities and health institutions -- can play a pivotal role in debunking myths with simple tags that link to factual information, University of California, Davis, researchers, suggest in a new study. Researchers found that fact-check tags located immediately below or near a post can generate more positive attitudes toward vaccines than misinformation alone, and perceived source expertise makes a difference. "In fact, fact-checking labels ...

An international team of researchers led by Swinburne University of Technology has demonstrated the world's fastest and most powerful optical neuromorphic processor for artificial intelligence (AI), which operates faster than 10 trillion operations per second (TeraOPs/s) and is capable of processing ultra-large scale data. Published in the prestigious journal Nature, this breakthrough represents an enormous leap forward for neural networks and neuromorphic processing in general. Artificial neural networks, a key form of AI, can 'learn' and perform complex operations with wide applications to computer vision, natural language processing, facial recognition, speech translation, ...

El Niño events have long been perceived as a driver for low rainfall in the winter and spring in Hawai'i, creating a six-month wet-season drought. However, a recent study by researchers in the University of Hawai'i at Mānoa School of Ocean and Earth Science and Technology (SOEST) revealed the connection between Hawai'i winter rainfall and El Niño is not as straightforward as previously thought. Studies in the past decade suggested that there are at least two types of El Niño: the Eastern Pacific and Central Pacific, when the warmest pool of water is located in the eastern or central portions of the ocean basin, respectively. El Niño events usually ...

WASHINGTON--Black and Hispanic people with COVID-19 and diabetes are more likely than Caucasians to die or have serious complications, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism. ...

With an estimated lifespan between 25 to 40 years, the queen conch (Strombus gigas) is a prized delicacy long harvested for food and is revered for its beautiful shell. Second only to the spiny lobster, it is one of the most important benthic fisheries in the Caribbean region. Unfortunately, the species faces a challenge of survival: how to endure and thrive, as populations are in a steady state of decline from overfishing, habitat degradation and hurricane damage. In some places, the conch populations have dwindled so low that the remaining conch cannot find breeding partners. This dire situation is urgent in ecological and economic terms. To preserve this most significant molluscan fishery in the Caribbean, ...

Osaka, Japan - Medical professionals all want to be able to quickly and correctly diagnose diseases. Their future ability to do so will depend on identifying what biochemicals are present in tissue sections, where the biomolecules are, and at what concentrations. For this purpose, mass spectrometry imaging--which can identify multiple biochemicals in a single experiment--will be useful. However, the stability of biomolecular sampling needs improvement to obtain the chemical distribution information with high spatial resolution. In the recent study published in Analytical Chemistry, researchers from Osaka University used mass spectrometry to image the distribution of ...

A scalpel-free alternative to brain surgery has the potential to benefit people with Parkinson's disease symptoms that are much more severe on one side of the body, new research suggests. More testing is needed, but the approach, which uses a technology called focused ultrasound, could offer a new option for patients whose symptoms are poorly controlled by medications and those who cannot or do not wish to undergo traditional brain surgery. "This small brain region, the subthalamic nucleus, had a very strong and potent effect on parkinsonian symptoms when we targeted it with precise, focused ultrasound energy," ...

The invention of optical fibers has revolutionized not only telecommunications but also sensing technology. Optical fiber sensors can measure strain, temperature, pressure, and many other physical parameters along the fibers, but they are currently immune to electromagnetic noise -- interference from other external electric or magnetic interactions. It is a desirable trait, until the effect of the electromagnetic field on the fibers needs to be measured. Now, an international team of researchers has used what was previously considered a 'damaged' part of an optical fiber to develop such a magnetic field sensor. They published details of their approach on Nov. 5 in Advanced Photonics Research. "This nature of immunity ...

Methylcyclopentadiene (MCPD) is an important monomer in the production of RJ-4 fuel, a high-energy-density rocket fuel, and various valuable products. Currently, MCPD is mainly obtained from the by-products of petroleum cracking tar at a very low yield of ~ 0.7 kg ton-1 and high price of ~10,000 USD ton-1. The exploration of highly efficient processes to convert renewable biomass to MCPD is stimulated by the energy and environment problems. Recently, a group led by Prof. LI Ning and Prof. ZHANG Tao from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) synthesized bio-based MCPD via direct hydrodeoxygenation of 3-methylcyclopent-2-enone (MCP) derived from cellulose. Their study was published in Nature Communications on Jan. 4. The researchers ...

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease. While human DNA is only passed down from parent to child, bacteria also have the habit of sharing some of their genes across species. This often applies to genes that make the bacteria resistant to antibiotics. The use and overuse of antibiotics provide an advantage to those bacteria that have acquired resistance genes, thus further promoting the spread of resistance and making it more difficult to treat infections. This development threatens large parts of modern healthcare. The rapid advances in DNA ...

Tokyo, Japan - Guillain-Barré syndrome is an infamous autoimmune neuropathy, yet genetic variants predisposing individuals to this disease have yet to be described. In a new study, researchers from Tokyo Medical and Dental University (TMDU) discovered two novel genetic variants in a protein made by antibody-forming immune cells, providing a mechanism for the development of the disease. The body's immune system is supposed to fight off invaders; however, in autoimmune diseases this defense goes rogue and attacks the host instead through the production of autoantibodies. Guillain-Barré syndrome (GBS) is an acutely developing, autoimmune peripheral neuropathy that leads to muscle ...
