Recent discoveries have revealed that Gamma-Ray Bursts originate from the most remote parts of the universe, releasing enormous amounts of energy in just 10 seconds. The high-redshift burst announcement adds to the body of research indicating these explosions are the most powerful in the Universe.
Researchers at Ohio State University have discovered that zebra mussels can colonize sandy and muddy substrates in Lake Erie, a finding that challenges previous assumptions about the mussel's habitat requirements. The study found that densities of some zebra mussel colonies exceed 20,000 animals per square meter.
Scientists at Columbia University detected the largest explosion ever witnessed, a gamma-ray burst, which occurred 12 billion years ago. The event released almost as much energy as the 10 billion trillion stars in the universe combined and was detected using a rapid series of phone calls between astronomers around the world.
Researchers discover that the CFTR protein acts as a receptor for Salmonella typhi, allowing it to be ingested and cleared from the body. This finding suggests that cystic fibrosis gene carriers may have protection against typhoid fever due to their abnormal CFTR protein.
