Wild bees: Champions for food security and protecting our biodiversity
Pollinators provide many benefits, including pollinating food crops and wild flowers in the countryside which in turn provide food for a wide range of animals. The threats to them are numerous and have already caused severe declines. The status of European pollinators, the causes of declines, and their value to society were presented by scientists at a special symposium of the 5th EurBee meeting held in Germany.

A celestial witch's broom?
The Pencil Nebula is pictured in a new image from ESO's La Silla Observatory in Chile. This peculiar cloud of glowing gas is part of a huge ring of wreckage left over after a supernova explosion that took place about 11,000 years ago. This detailed view was produced by the Wide Field Imager on the MPG/ESO 2.2-meter telescope.

Anti-HIV drug simulation offers 'realistic' tool to predict drug resistance and viral mutation
Pooling data from thousands of tests of the antiviral activity of more than 20 commonly used anti-HIV drugs, AIDS experts at Johns Hopkins and Harvard universities have developed what they say is the first accurate computer simulation to explain drug effects. Already, the model clarifies how and why some treatment regimens fail in some patients who lack evidence of drug resistance.

Solving the stink from sewers
The rotten egg gas leaking from sewer pipes and costing billions of dollars worldwide in odour control may soon be far less of a problem thanks to new research discussed at the 2012 International Water Association (IWA) conference this week. Trials with a magic mix of chemicals, called Cloevis, on sewers in the Gold Coast region in Australia stopped 99 per cent of the rotten egg gas or hydrogen sulphide emitted from these pipes.

Chronic fatigue syndrome is not linked to suspect viruses
The causes of chronic fatigue syndrome (CFS) have long eluded scientists. Since investigations by several laboratories have been unable to detect XMRV or pMLV in CFS patients, CII at Columbia's Mailman School collaborated on a study with several partners to resolve this issue. Findings show no evidence of the xenotropic murine leukemia virus (XMRV) or polytropic MLV in samples from the recruited CFS control subjects.
