• Bright Lighting Encourages Healthy Food Choices

    Dining in dimly lit restaurants has been linked to eating slowly and ultimately eating less than in brighter restaurants, but does lighting also impact how healthfully we order?

    New research findings forthcoming in the Journal of Marketing Research illustrate that those dining in well-lit rooms are about 16-24% more likely to order healthy foods than those in dimly lit rooms. Furthermore, the researchers found evidence that this effect is due mainly to the level of diners’ alertness. “We feel more alert in brighter rooms and therefore tend to make more healthful, forward-thinking decisions,” explains lead author Dipayan Biswas, PhD, University of South Florida.

  • Spring comes sooner to urban heat islands, with potential consequences for wildlife

    With spring now fully sprung, a new study by University of Wisconsin–Madison researchers shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners’ ears, but that tune could be alarming to some native and migratory birds and bugs.

  • Study shows how air pollution fosters heart disease

    Long-term exposure to air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. A major, decade-long study of thousands of Americans  found that people living in areas with more outdoor pollution —even at lower levels common in the United States — accumulate deposits in the arteries that supply the heart faster than do people living in less polluted areas.  The study was published May 24 online in The Lancet.

  • Squid populations on the rise

    Unlike the declining populations of many fish species, the number of cephalopods (octopus, cuttlefish and squid) has increased in the world's oceans over the past 60 years, a University of Adelaide study has found.

    The international team, led by researchers from the University's Environment Institute, compiled a global database of cephalopod catch rates to investigate long-term trends in abundance, published in Cell Press journal Current Biology.

  • Increased vegetation in the Arctic region may counteract global warming

    Climate change creates more shrub vegetation in barren, arctic ecosystems. A study at Lund University in Sweden shows that organisms, such as bacteria and fungi, are triggered to break down particularly nutritious dead parts of shrubbery. Meanwhile, the total amount of decomposition is reducing. This could have an inhibiting effect on global warming.

  • You are what you eat

    Biologists at Indiana University have significantly advanced understanding of the genetic pathways that control the appearance of different physical traits in the same species depending on nutritional conditions experienced during development.

    In many animals, nutrition -- not genetic differences -- controls the appearance of certain physical traits. Ants and bees, for example, grow into workers or queens based upon the food eaten as larvae.

  • Early Earth's air weighed less than half of today's atmosphere

    The idea that the young Earth had a thicker atmosphere turns out to be wrong. New research from the University of Washington uses bubbles trapped in 2.7 billion-year-old rocks to show that air at that time exerted at most half the pressure of today’s atmosphere.

  • Long-term exposure to particulate air pollutants associated with numerous cancers

    The study between the University of Birmingham and University of Hong Kong, published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, adds to growing concern around the health risks of prolonged exposure to ambient fine particulate matter.

  • Carbon dioxide fertilization is greening the Earth

    From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.
