Stanford, CA — Plants spend their entire lifetime rooted to one spot. When faced with a bad situation, such as a swarm of hungry herbivores or a viral outbreak, they have no option to flee but instead must fight to survive. What is the key to their defense? Chemistry. (more…)
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…)
In a new study, Brown University researchers demonstrate a new tool for visually tracking in real-time the transformation of a living population of stem cells into cells of a specific tissue. The “molecular beacons,” which could advance tissue engineering research, light up when certain genes are expressed and don’t interfere with the development or operation of the stem cells.
PROVIDENCE, R.I. [Brown University] — A novel set of custom-designed “molecular beacons” allows scientists to monitor gene expression in living populations of stem cells as they turn into a specific tissue in real-time. The technology, which Brown University researchers describe in a new study, provides tissue engineers with a potentially powerful tool to discover what it may take to make stem cells transform into desired tissue cells more often and more quickly. That’s a key goal in improving regenerative medicine treatments. (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.
The fact that bin Laden was killed by a team of highly trained soldiers – and not by a drone or bomb – spoiled the grand narrative of brave Muslim fighters vs. U.S. technology that bin Laden and al Qaeda had developed in their war against the United States.
“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…)
