In first moments of infection, a division and a decision

Scientists at UC San Diego School of Medicine have made a breakthrough discovery on the fate determination of T lymphocytes during an infection. They found that individual cells can make decisions about whether to become effector or memory cells almost immediately after exposure to a pathogen, suggesting that this process could be cruc...

Global warming felt to deepest reaches of ocean

A study by McGill University researchers shows that climate change has led to a decrease in ocean salinity, creating a freshwater lid that prevents mixing with warm waters underneath. This has resulted in the suppression of naturally rare events like the Antarctic polynya and contributed to the shrinking of Antarctic Bottom Water.
