Selecting life: Scientists find new way to search for origin of life

...of plausible prebiotic molecules, making literally millions of possible biomolecule/mineral pairs. It's an overwhelmingly large number of possibilities." DNA microarrays provide a means to address this problem. Microarrays are produced robotically to spot tens of thousands of microscopic droplets of DNA fr...

Researchers develop technologies to devour food pathogens

...ther pathogens, like salmonella, need thousands or millions of cells to cause infection. As of Sept. 26, 183 cases of illness were reported due to spinach contamination with a virulent strain of E. coli. "What is happening is unacceptable," Linton said.

Malaria may fuel spread of HIV in sub-Saharan Africa

...imate that tens of thousands of HIV infections and millions of malaria cases are likely the result of this co-infection. Using the town of Kisumu, Kenya on the shore of Lake Victoria as an example, Abu-Raddad estimates that 5 percent of all HIV infections are attributed to the heightened HIV viral load indu...

Sea urchin genome suprisingly similar to man and may hold key to cures

...y and inexpensive. One female can provide up to 20 millions eggs. The embryos develop in just three days and are transparent. Also, single cells can be easily observed live in the embryos. "If we know how these biological processes work, then we can begin to figure out how to intercede to repair and to he...

'Erectile dysfunction' drugs heighten natural anti-cancer activity

Because diabetes is a disease caused by impaired production or utilization of insulin, this work may help explain the connection between diabetes and poor healing. Says Martins-Gr...

A new target for painkillers

"We grafted the cells into mice that have spinal cord injuries and were encouraged by the results. The cells survived and integrated into the spinal cord, remaining at the site of transplantation and not ...
