Scientists report inhibition of cellular aging

Aging is the deterioration of a cell's ability to divide and grow as it gets older. This causes degradation of the body and age-related diseases. Prevention of aging is an instinctive desire of humans; thus, it is a task ...

Chemicals that cure malaria can kill weeds too

Plant biologists at The University of Western Australia have revealed the relationship between plants and the parasite that causes malaria is close enough to mean many antimalarial drugs are effective herbicides.

Mutant protein sheds lights on viral propagation

Some genetic mutations can cause a virus to flourish. Others make the virus wither away, unable to function normally and reproduce. Yet other genetic mutations only show their hand under certain conditions.

Sun's UV light helped spark life

High energy, ultraviolet radiation from the Sun is a known to hazard to life, yet the energy provided by our star has played an important role as the essential driver of life on Earth.

New therapeutic strategy against sleeping sickness
