| Pig pheromone proves useful in curtailing bad behavior in dogs Posted: 24 Aug 2014 06:31 PM PDT Androstenone can stop dogs from barking, jumping, researchers report. Androstenone is produced by pigs in their saliva or fat, but Boar Mate androstenone is synthesized in a laboratory. One spray of Boar Mate on Toto was all it took to set the wheels of experimentation in motion.       |
| Cutting emissions pays for itself, study concludes Posted: 24 Aug 2014 12:23 PM PDT Health care savings can greatly defray costs of carbon-reduction policies, experts report. But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions? Researchers looked at three policies achieving the same reductions in the U.S., and found that the savings on health care spending and other costs related to illness can be big -- in some cases, more than 10 times the cost of policy implementation.  |
| Mimicking natural evolution with 'promiscuous reactions' to improve the diversity of drugs Posted: 24 Aug 2014 12:23 PM PDT A revolutionary new scientific method will improve the diversity of 'biologically active molecules', such as antibiotics and anti-cancer agents. "Nature produces some amazing structures with really interesting biological activity, but the plant or animal did not design them. Instead the organisms gradually evolved both the chemical structures and the methods to produce them over millennia because they were of benefit. We wanted to capture the essence of this in our approach to discovering new drugs," said the lead author.  |
| Signatures of selection inscribed on poplar genomes Posted: 24 Aug 2014 12:23 PM PDT A team of researchers used a combination of genome-wide selection scans and analyses to understand the processes involved in shaping the genetic variation of natural poplar (Populus trichocarpa) populations. The approach applied genomics to ecological questions, and could help developing more accurate predictive climate change models.  |
| Simply complex: The origin of our body axes Posted: 24 Aug 2014 12:22 PM PDT One fundamental question in biology is what constitutes the basic type of the animal body plan and how did all the more complex forms, including that of humans, evolve from it. At the simplest level, this body plan can be described by the three axes. These three axes -- the familiar X, Y and Z axes from geometry -- are the anterior-posterior axis, which determines the position of the mouth in front and the anus at the rear, the dorsal-ventral axis, which in vertebrates separates the front of the body from the back, and the left-right axis, which creates a mirror-like symmetry of our extremities and left-right asymmetry of the organs.  |
| Evolutionary history of honeybees revealed by genomics Posted: 24 Aug 2014 12:22 PM PDT The first global analysis of genome variation in honeybees has been revealed by scientists. The findings show a surprisingly high level of genetic diversity in honeybees, and indicate that the species most probably originates from Asia, and not from Africa as previously thought. The honeybee (Apis mellifera) is of crucial importance for humanity. One third of our food is dependent on the pollination of fruits, nuts and vegetables by bees and other insects. Extensive losses of honeybee colonies in recent years are a major cause for concern.  |
| New monkey model of severe MERS-CoV disease established Posted: 21 Aug 2014 11:14 AM PDT Middle East respiratory syndrome coronavirus (MERS-CoV) infection in marmosets closely mimics the severe pneumonia experienced by people infected with MERS-CoV, researchers report, giving scientists the best animal model yet for testing potential treatments.  |
