Organically farmed cows are good for birds, according to a study of EU agri-environment schemes and birds in Finland. Organic cattle farming has a positive impact on the abundance of insect eating birds and birds such as swallows and martins that migrate over long distances.
Dietary supplementation with certain amino acids may be of benefit for some children with autism, according to researchers. The suggestion follows the discovery that one group of children with Autism Spectrum Disorder (ASD) share a similar profile of amino acid metabolites in their blood: with lower levels of so-called ‘branch chain’ amino acids – leucine, isoleucine and valine – and higher levels of ornithine, glutamine and glycine than usual.
Current food packaging, such as crisp and coffee packets, contain materials that act as a barrier against oxygen and moisture, essential for food preservation.
The human body is not well adapted for life beyond the Earth’s atmosphere. Without exercise, astronauts can lose 20% of muscle mass in a space flight lasting just five to 11 days, while bone density is depleted at a rate of 1-2% a month, according to Ruth Globus of Nasa’s Ames Research Center in CA, US.
