Africa's first large-scale HIV vaccine study launches

...nfection. The hope is that these HIV genes will produce a cellular immune response to HIV and cause the body to make killer cells that are programmed to recognize and destroy cells that are infected with HIV. The studies already completed with this vaccine suggest that it is generally well tolerated and t...

NASA predicts nongreen plants on other planets

...rocess by which plants use energy from sunlight to produce sugar. Organisms that live in different light environments absorb the light colors that are most available. For example, there is a type of bacteria that inhabit murky waters where there is little visible light, and so they use infrared radiation dur...

New technologies coming too fast for Indian farmers

...in 2003." Bt cottonseed, genetically modified to produce its own insecticide, was introduced in India in 2002. Between 2003 and 2005, the market share of Bt seed ?created through collaboration between Monsanto Co. and several Indian companies ?rose to 62 percent from 12 percent. Stone's research reveals th...

In-shell vaccine for chick disease

...nd Intervet UK, used a 'reverse genetic' system to produce new vaccine strains. Existing strains, which are usually delivered by less efficient spray or drinking water dosage, can prevent chicks hatching if delivered in the egg. The scientists have extracted a so-called spike protein from a pathogenic vi...

Penn study on olfactory nerve cells shows why we smell better when we sniff

... finding, plus the fact that both types of stimuli produce reaction in olfactory nerve cells, which control how our brain perceives what we smell, explains why we sniff to smell something, and why our sense of smell is synchronized with inhaling. "The driving force for such synchronization remained a mys...

Manipulating nature: Scientists query wildlife birth-control method

...eptive vaccine causes an animal's immune system to produce antibodies that act against some essential event or structure in the reproductive process. The antibodies can act against sperm, eggs or reproductive hormones, which prevent either fertilization or the production of sperm and ova. Proponents of t...

Grape expectations for healthier wine

...hnique could be used in the wine-making process to produce healthier wines without the added sulphites that can cause asthma and other conditions in some people. Mass-marketed grapes can remain in storage for months and are usually treated with sulphur dioxide to prevent decay. Although the sulphur dioxide...

...arallel," Weintraub said. Certain malignant tumors produce antibodies that reach the brain and cause an illness similar to encephalitis, she noted. The next step in Weintraub's research will be to launch a national study to see if her results will be confirmed in a larger population. "I don't want to ...

University of Alberta researchers unravel intricate animal patterns

... very simple and straightforward sets of rules can produce the complex kinds of patterns seen in nature," says Lewis, also from the Department of Biological Sciences. "Her work has stripped out the unnecessary detail to the core elements of communication that give rise to the patterns found in large scale gr...

Climate change could trigger 'boom and bust' population cycles leading to extinction

...nta Cruz. Favorable environmental conditions that produce abundant supplies of food and stimulate population booms appear to set the stage for population crashes that occur when several "good years" in a row are followed by a bad year. "It's almost paradoxical, because you'd think a large population would b...

Cartilage discovery offers arthritis hope

...r fibrils and examine how collagen cells manage to produce these relatively large fibrous structures which are 1,000 times their own size. Once scientists understand how the fibrils form and develop in healthy cartilage, they can then investigate what happens when things go wrong in diseases like osteoarth...

New molecular pathway could reveal how cells stick together

...organisms. Cells must interact with each other to produce system responses, like the remodeling of a tissue during development or for orchestration of an integrated immune response. One way they do this is by physically attaching to one another and to surfaces. Andrea Page-McCaw, assistant professor of biol...
