Genome of “extremophile” red alga offers insights
In the movie Alien, the title character is an extraterrestrial creature that can survive brutal heat and resist the effects of toxins.
In real life, organisms with similar traits exist, such as the “extremophile” red alga Galdieria sulphuraria.
In hot springs in Yellowstone National Park, Galdieria uses energy from the sun to produce sugars through photosynthesis. (more…)
EAST LANSING, Mich. — Humans could learn from how plants handle stress.
Federica Brandizzi, Michigan State University plant biologist, is using a grant from the National Institutes of Health to study how plants overcome stress as they grow. These pathways used to overcome stress are a key to growth. Without them plants, and animals, would die.
“When cells grow, they undergo trauma as growth is quite stressful,” Brandizzi said. “Since it’s very likely that these pathways have much in common between humans and plants, we should be able to gain insights into how plants and animals overcome stress and continue to grow as well.” (more…)
COLUMBUS, Ohio – The way the U.S. military killed Osama bin Laden sent a message every bit as powerful as the fact that he was killed in the first place, according to the author of a new history of suicide bombing.

“Bin Laden had built up this image of himself and al Qaeda as a morally superior David against the technological Goliath that is the United States,” said Jeffrey Lewis, a lecturer in the International Studies program at Ohio State University. (more…)
