When healthy people eat a low-gluten and fiber-rich diet compared with a high-gluten diet they experience less intestinal discomfort including less bloating which researchers show are due to changes of the composition and function of gut bacteria. The new study also shows a modest weight loss following low-gluten dieting. The researchers attribute the impact of diet on healthy adults more to change in composition of dietary fibers than gluten itself.

The study examined 123 different DNA markers in approximately 2,800 thinhorn sheep in British Columbia and the Yukon, with the goal of mapping population boundaries. Results show significant overestimation of certain subspecies of thinhorn sheep, like Stone's sheep, due to misclassification.

The first known interstellar object to visit our solar system -- named 'Oumuamua -- was detected in October 2017 by Hawaii's Pan-STARRS 1 telescope. But it was too faint for NASA's Spitzer Space Telescope to detect when it looked more than two months after the object's closest approach to Earth in early September. That 'non-detection' puts a new limit on how large the strange object can be, astronomers now report.

Truffles are the fruiting bodies of the ectomycorrhizal (ECM) fungal symbionts residing on host plant roots. In many Ascomycota and Basidiomycota lineages, truffle-forming species have evolved independently in nearly every major group. This suggests that symbiosis drives evolution of truffle diversity and selects for specific traits.

Results of the study, confirm that exposure to crude oil, at concentrations mimicking those measured in coastal areas following the Deepwater Horizon oil spill in 2010, significantly impaired olfactory function in the Atlantic stingray after just 48 hours of exposure.

Stealth-cap technology for light-emitting nanoparticles  

Scientists have succeeded in significantly increasing the stability and biocompatibility of special light-transducing nanoparticles. They have developed so-called ''upconverting'' nanoparticles that not only convert infrared light into UV-visible light, but also are water-soluble, remain stable in complex body fluids, and can be used to store medications. They have created a tool that could potentially make the fight against cancer more effective.

Emotional intelligence: A new criterion for hiring?  

The cognitive skills of a future employee are examined during a job interview. However, qualifications and a nice character don't necessarily mean that the interviewee will be a competent colleague. The individual's emotional intelligence has to be factored in, that is, his capacity to understand, regulate and manage emotions in the specific context of the work environment. Researchers have now devised an emotional intelligence test that measures emotional competences at work.

Rising sea levels may build, rather than destroy, coral reef islands  

Rising global sea levels may actually be beneficial to the long-term future of coral reef islands, such as the Maldives, according to new research. Low-lying coral reef islands are typically less than three meters above sea level, making them highly vulnerable to rising sea levels associated with climate change. However, research has found new evidence that the Maldives -- the world's lowest country -- formed when sea levels were higher than they are today.

Rare fossil bird deepens mystery of avian extinctions  

Today's birds descend from a small number of bird species living before the dinosaur extinction. Some of the birds that went extinct, the enantiornithines, were actually more common than and out-competed modern bird ancestors. Analysis of a newly described fossil, the most complete known from the Americas, demonstrates, too, that the enantiornithines were as agile and strong in flight as the ancestors of modern birds. Why, then, did enantiornithines die out and modern birds flourish?

Can scientists change mucus to make it easier to clear, limiting harm to lungs?  

For people with conditions such as cystic fibrosis and COPD, mucus can get too thick and sticky; coughing alone can't clear it. Infections develop, leading to severe chronic disease and early death. Now, for the first time, scientists have shown why coughing often cannot tear mucus apart and away from the airway lining. And they showed how to make mucus thinner and less sticky so coughing can become a therapeutic aid.
