Methicillin-resistant Staphylococcus aureus bacteria, more commonly known as MRSA. It is a bacteria resistant to many antibiotics; in medical facilities, MRSA causes causes life-threatening bloodstream infections and pneumonia. In this image, the MRSA (in yellow), is being ingested by neutrophil (in purplish blue), a type of white blood cell. Credit: National Institute of Allergy and [...]

Credit: Courtesy of Hallam lab     For multicellular life — plants and animals — to thrive in the oceans, there must be enough dissolved oxygen in the water. In certain coastal areas, extreme oxygen-starvation produces “dead zones” that decimate marine fisheries and destroy food [...]

A young vendace. Credit: Ian J Winfield     Two adult vendace, Britain’s rarest freshwater fish and a relic of the last ice age, were found in Bassenthwaite Lake in north-West England last month, more than a decade after being declared ‘locally extinct’. Last year, a single young vendace was recorded during the annual fish [...]

Pesticides more toxic for soil organisms in dry soil, at enhanced temperatures

Sinella curviseta are widely distributed. They form part of a huge crowd of soil organisms, which decompose organic material and build up humus. Credit: © C. Bandow     Soil organisms react more sensitive to marketable pesticides when exposed in dry soil and at enhanced temperatures. Both conditions may occur more often in the future [...]

Fall foliage season may be later, but longer on warmer Earth

Fall foliage season may be later, but longer on warmer Earth

The autumn foliage season in some areas of the United States could come much later and possibly last a little longer by the end of the century as climate change causes summer temperatures to linger later into the year, according to Princeton University researchers. The researchers collected data on leaf-change dates for several tree species [...]

The study, published Tuesday in the peer-reviewed open-access journal PeerJ, shows that nitrogen in the runoff ends up in algae [...]

Biodiversity does not always improve resistance of forest ecosystems to drought

Mixed forest. Credit: INRA-Charlotte Grossiord     Scientists from INRA, in collaboration with WSL (Switzerland) and European colleagues, studied the resistance of forests to drought according to the diversity of tree species. Due to climate change, parts of the world will face droughts that will affect forest health. Scientists from INRA, in collaboration with WSL[1] [...]

Mountain pine beetles get bad rap for wildfires, study says

Mountain pine beetles get bad rap for wildfires, study says

Following wildfires in 2011, a UW-Madison research team studied lodgepole pine trees in the Northern Rocky Mountains to examine whether earlier outbreaks of mountain pine beetles changed the ecological impact of the wildfires. Credit: Turner Lab     Mountain pine beetles get a bad rap, and understandably so. The grain-of-rice-sized insects are responsible for killing [...]
