Researchers at Johns Hopkins Children's Center have found that certain metabolites of an antipsychotic drug inhibit HIV replication in human cell cultures, but at high concentrations. The findings suggest possible anti-viral activity against other viruses.
Researchers found that manipulating fish populations can alter the flow of carbon between lakes and the atmosphere, with implications for global climate. The study reveals that even slight rearrangements of an intact ecosystem's food web can have far-reaching consequences.
Recent discoveries demonstrate that Gamma-Ray Bursts (GRBs) originate from the most remote parts of the universe, releasing as much energy in 10 seconds as the Sun emits in its entire lifetime. The uniform distribution on the sky and brightness distribution rule out galactic halo and suggest distances exceeding billions of light years.
