In 75 years’ time, the UK could be plagued by fly populations 250% up on today’s levels if forecasts of climate change prove accurate, ecologists have warned. Writing in a special climate change issue of the British Ecological Society’s Journal of Applied Ecology, Dave Goulson and colleagues from the University of Southampton found that if the worst case scenario for climate change occurs - a 5 deg C rise in temperature by 2080 - house fly numbers in the UK could explode.
Studies on the ecological impact of climate change has to date largely focused on butterflies and birds, two groups for which data on distribution and abundance abounds. Until now, ecologists have been less keen to study flies, but says Dr Goulson: “The annoyance and public health risks associated with large populations of flies are considerable, and potential increases in their abundance as a result of climate change are a cause for concern.”
Between January 2000 and December 2003 Dr Goulson and his colleagues monitored populations of calyptrate fly species - including the house fly Musca domestica and bluebottles Calliphora spp. - at six sites in Hampshire, three of which were near landfill sites. Over the four years they set almost 10,000 yellow sticky traps and caught more than 100,000 calyptrate flies.

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
