Scientists succeed in cloning human embryos from eggs matured in the lab

...at there was a long way to go and many problems to overcome before he and his colleagues could reach their goal. "None of these early embryos developed to the blastocyst stage, and failure to do so could reveal some problems in gene activation, especially in cloned embryos. So, first we have to understand ho...

Harmless virus may hold key to more effective HIV drug discovery

...ul in identifying compounds that show potential to overcome drug resistance A simple, harmless virus might hold the key to the more effective and efficient development of HIV and anti-viral drugs, UCI chemical biologists have found. In order to better identify compounds that can outmaneuver a virus' effort ...

FSU scientist warns North Atlantic right whale facing extinction

...nually over the last five years, are inadequate to overcome this level of mortality," the paper states.

Analysis of flower genes reveals the fate of an ancient gene duplication

...ignificant challenge. One way in which this can be overcome is for researchers studying a particular modern-day gene to look at neighboring genes in different related species. Genes derived from a common ancestral gene region will still share similarities in neighboring gene sequences, both in terms of gene i...

Virologist finds contagious equine flu in dogs

.... For a new virus to enter another species it must overcome a number of barriers, such as finding a cell receptor to bind to in order to enter the cell and to reproduce sufficiently in the new host. "There are probably many examples of viruses jumping species, but then it becomes a dead-end issue," said Dubo...

Hopkins scientists uncover 'tags' that force proteins to cell surface

... we can force proteins to the cell surface, we can overcome obstacles that have prevented laboratory study of some really important proteins," says Li. The application of these surface tags to force protein transportation to the cell surface is the subject of a Patent Cooperation Treaty (PCT) patent applicati...

Researchers make 'embryonic-like' stem cells from umbilical cord blood

Researchers find molecule that inhibits regrowth of spinal nerve cells

...id. Dr. Parada added that several factors must be overcome before spinal-cord regeneration and recovery from injury can occur in a meaningful way for patients. "We have to figure out how to dissolve the glial scars or impede their formation," he said. "We also need to get mature neurons to be better at grow...

Columbia scientists develop cancer terminator viruses

...into a specially designed non-replicating virus to overcome one of the major hurdles of gene therapy: its tendency to kill normal cells in the process of eradicating cancer cells. The virus eradicated prostate cancer cells in the lab and in animals, while leaving normal cells unscathed. The present cancer...

DDT-resistant insects have additional genetic advantage that helps resistance spread

...newer compounds subsequently introduced to try and overcome resistance. The World Health Organization estimates that during the period of DDT use, approximately 25 million human lives have been saved. Today pyrethroids are most commonly used in mosquito control but they act on the same target in the nervous ...

Techniques available to detect soil that inhibits destructive soybean pest

...nematode populations constantly change so they can overcome certain types of resistance, including even plants that are bred to be resistant to the organisms." Westphal and his research team conducted a survey throughout Indiana to locate nematode-suppressive soils in an effort to make this tool more availab...

Purdue researchers find key to rice blast fungus

...e over centuries, according to genetic experts. To overcome the fungus' wiles, researchers need to know more than just the one pathway. "We want to know how the plant and the fungus talk," Xu said. "We need to know the signal, or ligand, the rice plant gives to the receptor on the fungus that allows the pene...

Software 'agents' could help unmask reality of disease clusters

...a, suggests that new agent software may be able to overcome some of these problems. Software agents are programmes that can respond to changes in their environment, generate and attempt to achieve goals, and have the capacity to interact with other agents and even co-operate. This means that agents could be...

Purdue's gold nanorods brighten future for medical imaging

...d cell. Gold nanorods represent a possible way to overcome barriers in developing advanced medical imaging techniques that use light to analyze blood vessels and underlying tissues. "One obstacle is that light in the visible spectrum does not pass through tissue very well," said Alexander Wei, an associate ...

Biotechnology's newest chemical tool
