New study in moths shows insects not entirely ruled by instinct

By examining the brain activity of moths, researchers have found that the behavior of these insects isn’t ruled entirely by instinct. Rather, they can learn which odors mean food.

The findings are more than academic: The researchers hope to develop methods for using trained moths to detect odors of interest for defense industry and law enforcement – such as odors given off by biological and chemical weapons.

Animal behaviorists have historically argued that most insects have a

Secret behind hard exoskeletons, spreading wings revealed

A team of biologists has discovered the structure and genetic sequence of the hormone that makes insects develop their hard outer shells and allows them to spread their wings. The findings answer more than 40 years of questions about insect development.

Using the fruit fly, the researchers determined the genetic sequence of the hormone bursicon, confirmed that it is responsible for the hardening of the soft exoskeleton after each molt of an insect as it grows into adulthood, and discovered

LSU researcher discovers new bird during expedition to Peru

He saw it. He heard it. But he needed proof.

For almost four years, LSU research associate Daniel Lane was haunted by the memory of an unusual, yellowish bird. He and an associate caught a glimpse of it while bird watching in Peru. They even recorded some of its song. Right away, they knew it was something new. Something different.

Now, thanks to Lane, a specimen of that bird – previously unknown to science – rests in a Lima museum and it will soon bear a name of Lane&#1

Carnivore species are predicted to be at increased extinction risk from human population growth

Research published online today reveals that many of the world’s carnivores are at greater risk of extinction than previously thought. Close to a quarter of the world’s mammals are already at high risk of extinction. Any chance of reversing this trend depends on understanding what makes some species vulnerable and others resilient. And that depends on being able to predict extinction risk.

Now, a new model based on a phylogenetic analysis of the mammalian order Carnivora, described online

Norwich scientists part of EU project to fight drug-resistant ’superbugs’

The John Innes Centre (JIC)Norwich, has today announced its key role in an EU-funded consortium to develop novel antibiotics in the war against drug-resistant superbugs. The ’CombiGyrase’ consortium of 7 laboratories from Germany, Italy, Spain, Switzerland and the UK will receive 1.56 million Euros over three years, with 228,000 Euros (£150,000) going to the JIC.

“There is a lot of concern about the rise of drug-resistant bacteria, so called superbugs, such as MRSA”, says Professo

Genetic mutation found that is major contributor to type 1 diabetes

A natural mutation of a gene that helps regulate the reactivity of the immune system is a major contributor to type 1 diabetes, Medical College of Georgia researchers have found.

The newly discovered gene, SUMO-4, controls the activity of NFêB, a molecule that in turn controls the activity of cytokines, proteins that regulate the intensity and duration of the immune response, according to research that will be published in the August print issue of Nature Genetics and online July 11.
