VTT Technical Research Centre of Finland Ltd has been the first to publish a scientific study on the successful generation of hybrid lager yeasts. For centuries the same few yeast strains have been used in the production of lager beer, in contrast to ale, whisky, wine and cider, for which there is a wide range of yeast strains available to produce different nuances of flavour. VTT has been developing hybrid lager yeasts so as to impart new flavour to the beer and accelerate the production process. Traditionally, even very different tasting lagers have been produced using ...

Bethesda, MD (March 5, 2015) -- A better understanding of the stomach's immune response to Helicobater pylori (H. pylori) infection could lead to new therapies targeting damage in the stomach, report researchers in the March issue of Cellular and Molecular Gastroenterology and Hepatology, the basic science journal of the American Gastroenterological Association. When H. pylori infection is present, the alarmin Interleukin (IL)-33 is a critical messenger that triggers changes necessary for coping with the injuries caused by the infection. Specifically, it actives an ...

San Diego, CA--Prenatal exposure to low doses of the environmental contaminants polychlorinated biphenyls, or PCBs, change the developing brain in an area involved in metabolism, and some effects are apparent even two generations later, a new study finds. Performed in rats, the research will be presented Friday at the Endocrine Society's 97th annual meeting in San Diego. Hereditary effects included increased body weight, but only in descendants of females--and not males--exposed to PCBs in the womb, said study co-author Andrea Gore, PhD, professor at the University of ...

San Diego, CA--Early exposure in the human womb to phthalates, which are common environmental chemicals, disrupts the masculinization of male genitals, according to a new study that will be presented Sunday at the Endocrine Society's 97th annual meeting in San Diego. Phthalates are hormone-altering chemicals, called endocrine disruptors, and are found in many plastics, containerized foods and personal care products. The clinical study not only confirms similar results of animal studies, it also provides new information about how phthalates target a main pregnancy hormone, ...

San Diego, CA--Exposure during pregnancy to a combination of fire retardant chemicals and phthalate chemicals--both present in the average home--can contribute to autistic-like behaviors in the offspring, according to an animal study to be presented Thursday at the Endocrine Society's 97th annual meeting in San Diego. "Our research points to potentially preventable causes of autism, which remains a diagnosis with enormous social costs and limited solutions," said lead study author Stephanie Degroote, MSc, a PhD student at the University of Sherbrooke in Sherbrooke, Quebec, ...

SAN DIEGO, CA and BRUSSELS, BELGIUM-A new economic analysis found exposure to endocrine-disrupting chemicals likely costs the European Union €157 billion ($209 billion) a year in actual health care expenses and lost earning potential, according to a new series of studies published in the Endocrine Society's Journal of Clinical Endocrinology and Metabolism. The authors presented the findings today at simultaneous press events at ENDO 2015, the Endocrine Society's 97th Annual Meeting & Expo, and in Brussels, Belgium. Global experts in this field concluded that ...

San Diego, CA--Male partners of infertile obese females may increase the odds of conceiving a child by improving their own weight and dietary habits, preliminary results from a pilot study from Canada suggest. The results will be presented Thursday, March 5, at ENDO 2015, the annual meeting of the Endocrine Society in San Diego. "We were thrilled to observe a significant relationship between some dietary changes and weight loss in men with the occurrence of a conception, when we compared the men in couples who conceived with those who did not," said lead author Matea ...

San Diego, CA--The composition of intestinal bacteria and other micro-organisms--called the gut microbiota--changes over time in unhealthy ways in black men who are prediabetic, a new study finds. The results will be presented Friday at the Endocrine Society's 97th annual meeting in San Diego. Researchers previously found that the gut microbiota--containing both beneficial and harmful microbes--can affect human health in many ways and that the mix of this community of microscopic organisms differs in people with Type 2 diabetes compared with healthy individuals. However, ...

San Diego, CA--A synthetic nasal formulation of the hormone oxytocin reduced caloric intake in healthy men, particularly consumption of fatty foods, after a single treatment, a new study finds. The results, to be presented Sunday at The Endocrine Society's 97th annual meeting in San Diego, confirm those of animal studies showing oxytocin reduces food intake. Oxytocin nasal spray reportedly lowered the number of calories men consumed at a subsequent breakfast whether they were normal weight or overweight. In addition, the researchers found that oxytocin improved metabolic ...

Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, spotted four images of a distant exploding star. The images are arranged in a cross-shaped pattern by the powerful gravity of a foreground galaxy embedded in a massive cluster of galaxies. The supernova discovery paper will appear on 6 March 2015 in a special issue of Science celebrating the centenary of Albert Einstein's theory of general relativity. Whilst looking closely at a massive elliptical galaxy and its associated galaxy cluster MACS J1149+2223 -- whose light took over 5 billion years ...

San Diego, CA--A new soybean oil genetically modified to be healthier than conventional soybean oil causes obesity, pre-diabetes and fatty liver in a nearly identical manner to that of regular soybean oil when part of a typical American high-fat diet, an animal study shows. The study results will be presented Friday at The Endocrine Society's 97th annual meeting in San Diego. The recently introduced high-oleic soybean oil (Plenish, from DuPont Pioneer) had not been tested for long-term metabolic effects until this study, said the senior investigator, Frances Sladek, PhD, ...

A pilot study in 51 N.C. classrooms shows the effectiveness of a new measure in assessing the quality of practices in inclusive preschools. Not only is the Inclusive Classroom Profile (ICP) a reliable instrument, researchers say it also reveals the types of inclusive settings that may be best serving preschoolers with disabilities. "Inclusion encourages active participation and a sense of belonging and membership for all children, with and without disabilities, who learn and develop in the same classroom," explained the study's lead author Elena P. Soukakou, senior lecturer ...

New York University chemists have developed a computational approach for determining the viability and suitability of complex molecular structures--an advancement that could aid in the development of pharmaceuticals as well as a range of other materials. "Understanding how molecules interact and achieve stable conformations in different environments is vital to many industries," says Mark Tuckerman, a professor in NYU's Department of Chemistry and the senior author of the study, which appears in the journal Proceedings of the National Academy of Sciences. "However, the ...

Scientists from the University of Southampton have found that ocean tides have changed significantly over the last century at many coastal locations around the world. Increases in high tide levels and the tidal range were found to have been similar to increases in average sea level at several locations. The findings of the study are published online in the journal Earth's Future. It is well documented that global average sea levels are rising; but tide levels, have generally been considered to have undergone little change on decadal time scales. It is also often ...

New Haven, Conn. - For once, slower is better in a new piece of technology. A Yale lab has developed a new, radio frequency processing device that allows information to be controlled more effectively, opening the door to a new generation of signal processing on microchips. One of the keys to the technology involves slowing information down. The new system, described in the March 5 edition of the journal Nature Communications, combines photons and phonons -- electromagnetic energy and sound energy -- to conduct sophisticated signal processing tasks by harnessing the properties ...

Dr. Liang Luo and associate prof. Jianchao Cai, a renowned researcher on fractal and capillarity and guest chief editor of FRACTALS, have published their latest paper entitled Numerical simulation of tortuosity for fluid flow in two-dimensional pore fractal models of porous media. The tortuosity of different generations of Sierpinski carpet is calculated and analyzed by the finite volume method. A simple linear relation between the generations and tortuosity in pore fractal model of porous media is obtained. The results show a more realistic tortuosity predication for ...

Weight loss surgery does not stunt the growth of obese children when applied within a clinical pathway. It is a safe option to use and provides hope for youngsters who are unable to shed pounds through weight management programs that include counseling and lifestyle changes. So says Professor Aayed Alqahtani of King Saud University (KSU) in Saudi Arabia, after tracking the progress of almost 300 children who had all undergone such surgery through a standardized clinical pathway that was created and applied by Alqahtani in his practice at KSU. The findings are published ...

Over the next two centuries, climate change is likely to impact everything from industrial agriculture to the shape of our coastlines. The changing climate will certainly cause huge changes around the world, and the challenge is to predict exactly what impact those changes will have. In the world of marine science, this means grappling with a process called ocean acidification. As human activity pumps carbon dioxide into the atmosphere, some of the carbon dioxide gets absorbed into the sea, which raises its acidity. Scientists have been concerned about this for more than ...

The planet candidate was spotted using a spectrometer which measures the 'wobble', small changes in the wavelength of light emitted by a star, caused as a planet orbits it. In 2014 researchers revisiting the data said that the 'planet' was actually just noise in the data caused by starspots. The possible existence of the planet was widely dismissed without further questioning. But now researchers from Queen Mary University of London (QMUL) and University of Hertfordshire have questioned the methods used to challenge the planet's existence. The statistical technique used ...

LOS ANGELES (March 5, 2015) - The benefits of weight loss surgery, along with a treatment plan that includes exercise and dietary changes, are well documented. In addition to a significant decrease in body mass, many patients find their risk factors for heart disease are drastically lowered and blood sugar regulation is improved for those with Type 2 diabetes. Some patients, however, do not experience the optimal weight loss from bariatric surgery. The presence of a specific methane gas-producing organism in the gastrointestinal tract may account for a decrease in optimal ...

Tropical Cyclone 15S formed in the Mozambique Channel of the Southern Indian Ocean, and the Global Precipitation Measurement or GPM core satellite gathered data on its rainfall rates. The GPM (core satellite) flew over the northwestern half of newly formed Tropical Cyclone 15S on March 5 at 15:36 UTC (10:36 a.m. EST). The GPM satellite is managed by both NASA and the Japan Aerospace Exploration Agency known as JAXA. GPM's Microwave Imager (GMI) instrument found that the heaviest precipitation was then occurring on the western side of the circulation center. Powerful ...

Bubbles gushing from melting glaciers and their icebergs make fjords the noisiest places in the oceans, a new study of waters near Alaska and Antarctica shows. The underwater noise is much louder than previously thought, researchers found. That led them to ask how the noise affects the behavior of harbor seals and whales in Alaska's fjords. "The ocean ambient sound gives us clues to the physical processes going on, but it also is an important aspect of the environment in which marine mammals and fish live. Like teenagers at a loud rock concert, the seals and whales modify ...

No one really knows how the High Plains got so high. About 70 million years ago, eastern Colorado, southeastern Wyoming, western Kansas and western Nebraska were near sea level. Since then, the region has risen about 2 kilometers, leading to some head scratching at geology conferences. Now researchers at the Cooperative Institute for Research in Environmental Sciences (CIRES) and the Department of Geological Sciences at the University of Colorado Boulder have proposed a new way to explain the uplift: Water trapped deep below Earth's crust may have flooded the lower ...

This news release is available in German. The water content of soil has a great impact on the regional climate, but many of the connections are still not clear. Researchers at ETH Zurich's Institute for Atmospheric and Climate Science, together with colleagues from Belgium and the Netherlands, examined when and where it rains most frequently on summer afternoons. They wanted to clarify whether more rain fell on days when the soil was dry or moist. And where exactly it was most likely to rain on these days. The contradictory findings of other scientists was the reason ...

Good supervisors aren't easily duped by the motives of underlings who go the extra mile - they know when an employee is sucking up to them because of personal ambition, or when such actions truly have what's best for the organization at heart. This is one of the insights from a study in Springer's Journal of Business and Psychology, led by Magda Donia of the University of Ottawa in Canada. Supervisors play an important role in making decisions about rewards and promotions within an organization. They should therefore be able to effectively distinguish between so-called ...
