New molecular pathway could reveal how cells stick together

...lular adhesion defect that causes problems for the animal at the tissue level." Now she plans to find how ninjurin affects breathing tube development, as well as the role it plays in immunity. "The immune system is all about immune cells circulating around and being able to attach to tissues that need th...

Is there a pilot in the insect?

...y at the outset. These hidden forces underlying animal behavior can then be understood more exactly by permanently shuttling between biology and robotics. These principles have been tried and tested for millions of years, and today they need to be applied to aerospace, because the phases in which an air...

Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

...y has already shown great promise in studies using animal models and human cells in culture, according to the researchers. The phase I trial, which will eventually enroll 24 patients with head and neck cancer, has three experimental arms, each including a DC-based vaccine containing p53-derived T cell-s...

New biofuels process promises to meet all US transportation needs

...ear from agricultural sources such as crop wastes, animal manure, grains and other crops. The remaining biomass could come from sources including fuel wood from forests, wastes left over from wood processing mills and paper mills, and construction and demolition debris. The process also offers potential ...

Scripps research team discovers a chemical pathway that causes mice to overeat and gain weight

...ccumulation, and thus may provide a very important animal model for determining the importance of inflammation in obesity and in the conversion of obesity to type 2 diabetes." Ultimately, better understanding of the role of EP3 receptors in feeding and obesity could lead to the development of treatments ...

Bioluminescence at the service of a novel cerebral imaging technique

...rm recordings. Such maps do not yet exist for any animal species, including man. A funding application has been made to the ANR in order to build up functional maps of the Drosophila brain. These maps are a prerequisite to producing a mass of data on the global activity of the entire brain which wil...

What recognizes what in plant disease resistance?

Protein sensor for fatty acid buildup in mitochondria

...e." "One of our challenges is how to develop an animal model of this disease that we can use to determine if reduced dietary fat and carnitine supplements offer hope in the treatment of PKAN in humans," said Suzanne Jackowski, Ph.D., a member of the Infectious Diseases department at St. Jude and a co-aut...

Prenatal cocaine's lasting cellular effects

... "We thought that it was important to set up an animal model that recapitulates a key feature of human abuse -- that being intravenous exposure to low doses of cocaine," Stanwood said. A few years ago, Stanwood and Levitt, professor of Pharmacology and director of the Vanderbilt Kennedy Center, estab...

No carrier necessary: This drug delivers itself

Bats prey on nocturnally migrating songbirds

...ique not only among bats but also within the whole animal kingdom. Although carnivorous bats feeding on small-sized vertebrates are not rare, they all live in the Tropics and collect their prey from substrates. The few species of falcons which capture migratory birds along the Mediterranean and African coas...
