  • Why you should exercise with friends

    Exercising together brings us closer to one another, while exercising with those close to us improves our performance. Those are the conclusions of an Oxford University study published this Friday in the journal PLoS ONE.

  • Looking into a Chameleon's Eye

    Well known among nature’s best tricksters for their ability to change color to fit their background, chameleons have yet another talent up their lizardly sleeves – eyes that swivel around and appear to be looking in two directions at once.

  • Food's impact on our brain found to be similar to drugs

    An international group of researchers have found that food craving activates different brain networks between obese and normal weight patients. This indicates that the tendency to want food may be 'hard-wired' into the brain of overweight patients, becoming a functional brain biomarker. Obesity is one of the most difficult problems facing modern society. Treating obesity is…

  • Even safe levels of air pollution found to have health impacts in European study

    Particulate matter and NO2 air pollution are associated with increased risk of severe heart attacks despite being within European recommended levels, according to research presented at ESC Congress today by Dr Jean-Francois Argacha, a cardiologist at University Hospital Brussels (UZ Brussel-Vrije Universiteit Brussel), in Belgium.1"Dramatic health consequences of air pollution were first described in Belgium in…

  • Walrus's hit the beaches again

    On both sides of the Bering Strait, summer sea ice has once more dropped to a level that is driving thousands of walruses onto coastal beaches. Photos taken in Ryrkaypiy in Chukotka, Russia show an estimated 5,000 walruses hauled out in that spot, while across the strait in the United States, thousands more are hauled out…

  • Can rain clean the atmosphere?

    As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, and organic particles. Atmospheric chemists at…

  • Study links air pollution to low GPAs

    A University of Texas at El Paso (UTEP) study on children’s health has found that fourth and fifth graders who are exposed to toxic air pollutants at home are more likely to have lower GPAs.

  • New study predicts future Antarctic ice loss

    A new international study is the first to use a high-resolution, large-scale computer model to estimate how much ice the West Antarctic Ice Sheet could lose over the next couple of centuries, and how much that could add to sea-level rise. The results paint a clearer picture of West Antarctica’s future than was previously possible.…

  • Dust in the Waters

    Each spring, powerful dust storms in the deserts of Mongolia and northern China send thick clouds of particles into the atmosphere. Eastward winds sweep these particles as far as the Pacific, where dust ultimately settles in the open ocean. This desert dust contains, among other minerals, iron — an essential nutrient for hundreds of species…

  • NASA's latest satellite data reveals global sea level rise

    Global sea levels have risen nearly 3 inches in less than 25 years, with some locations around the world rising more than 9 inches, according to NASA’s latest satellite data. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future.
