Simulations dispute dogma: rocky planets may orbit many double stars

Luke Skywalker’s home in “Star Wars” is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets have been identified circling such binary stars, and many researchers believe rocky planets cannot form there. Now, mathematical simulations show that Earthlike, solid planets such as Tatooine likely exist and may be widespread. (more…)

Hoch allergene Pflanze Ragweed mit enormem Ausbreitungspotenzial in Europa

Ragweed – auch bekannt als Ambrosie – gehört zu den Pflanzen mit dem am stärksten allergieauslösenden Pollen. Diese aus Nordamerika eingeschleppte Art breitet sich seit einigen Jahrzehnten auch in Mitteleuropa aus. Ein internationales ForscherInnenteam um Franz Essl vom Department für Botanik und Biodiversitätsforschung der Universität Wien hat in einer neuen Studie herausgefunden, dass die durch den Klimawandel begünstigte Verbreitung der Pflanze eine massive Zunahme der Pollenbelastung verursacht – bis zum Jahr 2050 soll sie sich gar vervierfachen. Die Ergebnisse der Studie erscheinen aktuell im renommierten Fachmagazin “Nature Climate Change”. (more…)

Berkeley Lab Study Shows How to Predict Metamaterial Nonlinear Optical Properties

Metamaterials – artificial nanostructures engineered with electromagnetic properties not found in nature – offer tantalizing future prospects such as high resolution optical microscopes and superfast optical computers. To realize the vast potential of metamaterials, however, scientists will need to hone their understanding of the fundamental physics behind them. This will require accurately predicting nonlinear optical properties – meaning that interaction with light changes a material’s properties, for example, light emerges from the material with a different frequency than when it entered. Help has arrived. (more…)

‘Deep Web Search’ May Help Scientists

When you do a simple Web search on a topic, the results that pop up aren’t the whole story. The Internet contains a vast trove of information — sometimes called the “Deep Web” — that isn’t indexed by search engines: information that would be useful for tracking criminals, terrorist activities, sex trafficking and the spread of diseases. Scientists could also use it to search for images and data from spacecraft. (more…)

Ancient rocks show life could have flourished on Earth 3.2 billion years ago

A spark from a lightning bolt, interstellar dust, or a subsea volcano could have triggered the very first life on Earth.

But what happened next? Life can exist without oxygen, but without plentiful nitrogen to build genes – essential to viruses, bacteria and all other organisms – life on the early Earth would have been scarce. (more…)

Impact of Radiant Temperature on Comfort

By Guest PostMay 27, 2015Small Business, Technologyair conditioner, hvac provider, michelle patterson, radiant flooring, radiant heat, radiant temperature

What is radiant temperature? One way to think about radiant temperature is to think about stepping into a car on a hot summer day. The heat from the dash board and steering wheel can be hot to the touch and unbearable. The heat can linger for minutes until the cars air conditioner cools the cabin. In your home the fire place is often a form of radiant heat. In the days before electricity, the warmth from a fire could mean the difference between life and death during a harsh winter. Today many use space heaters as a form of radiant heat in the home.
