  Green trees deliver green benefits
The economic benefits of greening urban areas outweigh the costs, a new US study has found.
  Food supply may fall 25% by 2050, says UN
Up to a quarter of global food production could be lost by 2050 due to the combined impact of such problems as climate change, land degradation and water scarcity, the United Nations says.
  Argentine ants give weeds a boost
In a double blow to the environment, Argentine ants are not only outcompeting native ants, but they are helping spread weeds, Australian research has found.
  Temperature spikes key to malaria spread
Climate change is influencing the spread of malaria in ways far more complicated than previously thought, according to US researchers.
  Galactic impact leaves Milky Way ringing
The effects of a small galaxy colliding with our own almost two billion years ago are still being felt, say an international team of astronomers.
  Biomaterial helps rebuild broken bones
A synthetic biomaterial that encourages the body to create bone could be the answer to successful bone grafts and treating bone disease, say Australian researchers.
  Biofuel rocket engine passes test run
The aerospace industry may become a little greener, after the recent test firing of a small rocket engine using commercially available biodiesel.
  Resistance gene stops rust in wheat
The sequencing of a gene that gives wheat a long-lasting ability to resist destructive fungal diseases could pave the way for hardier wheat strains, say researchers.
  Stress, abuse damages childhood genes
Childhood abuse appears to permanently change a person's response to stress, possibly making them more susceptible to suicide, new research suggests.
  Most wars occur in rich wildlife areas: study
Most wars in the last half-century occurred in places that shelter some of the most biologically diverse and environmentally threatened wildlife on earth, a new study reports.
  Mice shed light on obesity gene
German scientists have shown how a gene long associated with obesity might make people fat, a finding that could lead to new drugs to help control weight.
