  • Diet drinks may not “save” you calories

    Want fries with that diet soda? You aren’t alone, and you may not be “saving” as many calories as you think by consuming diet drinks. A new study that examined the dietary habits of more than 22,000 U.S. adults found that diet-beverage consumers may compensate for the absence of calories in their drinks by noshing on…

  • Air Quality in Scotland continuing to improve

    A new report published today shows Scottish emissions of most air pollutants have continued to fall, with significant reductions in emissions of all air pollutants since 1990.The announcement of the official figures was welcomed by Environment Minister Aileen McLeod who said an updated action plan to tackle nitrogen dioxide would soon be published.Dr McLeod said: “Air pollution…

  • Why we're wired for laziness

    Those of you who spend hours at the gym with the aim of burning as many calories as possible may be disappointed to learn that all the while your nervous system is subconsciously working against you. Researchers reporting in the Cell Press journal Current Biology on September 10 have found that our nervous systems are…

  • Lunar crust found to be highly fractured

    Scientists believe that about 4 billion years ago, during a period called the Late Heavy Bombardment, the moon took a severe beating, as an army of asteroids pelted its surface, carving out craters and opening deep fissures in its crust. Such sustained impacts increased the moon’s porosity, opening up a network of large seams beneath…

  • Oceanic Phytoplankton contribute to ice formation in clouds

    Researchers from the Arctic Research Programme, managed at British Antarctic Survey, have shown for the first time that phytoplankton (plant life) in remote ocean regions can contribute to rare airborne particles that trigger ice formation in clouds.Results published today in the journal Nature show that the organic waste from life in the oceans, which is ejected into the atmosphere…

  • Is the fate of the polar bear really doomed?

    With global warming and melting ice, it isn’t easy being a polar bear anymore. Some studies have predicted that polar bears could very well be extinct by the end of the century. The good news is not all researchers think the bears are absolutely doomed. Scientists at the American Museum of Natural History (AMNH) have…

  • MIT study shows climate change mitigation potential of geoengineering the oceans

    Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl sulfide (DMS) into the atmosphere, where it forms sulfate aerosols,…

  • The long-term effects of the Exxon Valdez oil spill

    For 25 years, methodical research by scientists has investigated the effects of the Exxon Valdez oil spill in 1989 on Alaskan communities and ecosystems. A new study released today into the effects of the 1989 Exxon Valdez oil spill in Alaska shows that embryonic salmon and herring exposed to very low levels of crude oil…

  • Ice sheets may be more resilient than previously thought

    Sea level rise poses one of the biggest threats to human systems in a globally warming world, potentially causing trillions of dollars' worth of damages to flooded cities around the world. As surface temperatures rise, ice sheets are melting at record rates and sea levels are rising.But there may be some good news amid the…

  • Farm air may prevent asthma in children

    For researchers trying to untangle the roots of the current epidemic of asthma, one observation is especially intriguing: Children who grow up on dairy farms are much less likely than the average child to develop the respiratory disease. Now, a European team studying mice has homed in on a possible explanation: Bits of bacteria found…
