Malagasy Chameleon Spends Most Of Its Short Life In An Egg:
There is a newly discovered life history among the 28,300 species of known tetrapods, or four-legged animals with backbones. A chameleon from arid southwestern Madagascar spends up to three-quarters of its life in an egg. Even more unusual, life after hatching is a mere 4 to 5 months. No other known four-legged animal has such a rapid growth rate and such a short life span.
Newcomer In Early Eurafrican Population?:
A complete mandible of Homo erectus was discovered at the Thomas I quarry in Casablanca by a French-Moroccan team co-led by Jean-Paul Raynal, CNRS senior researcher at the PACEA laboratory (CNRS/Université Bordeaux 1/ Ministry of Culture and Communication). This mandible is the oldest human fossil uncovered from scientific excavations in Morocco. The discovery will help better define northern Africa's possible role in first populating southern Europe.
What do humans and single-celled choanoflagellates have in common? More than you'd think. New research into the choanoflagellate genome shows these ancient organisms have similar levels of proteins that cells in more complex organisms, including humans, use to communicate with each other.
An Impossible Coexistence: Transgenic And Organic Agriculture:
The cultivation of genetically modified maize has caused a drastic reduction in organic cultivation of this grain and is making their coexistence practically impossible. This is the main conclusion reached in one of the first field studies in Europe carried out by a researcher of the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona, who has analysed the situation in Catalonia and Aragon, Europe's main producers of transgenic foods.
Eating Broccoli May Keep Prostate Cancer Away, Study Suggests:
Eating one or more portions of broccoli every week can reduce the risk of prostate cancer, and the risk of localised cancer becoming more aggressive.
Worms Do Calculus To Find Meals Or Avoid Unpleasantness:
Thanks to salt and hot chili peppers, researchers have found a calculus-computing center that tells a roundworm to go forward toward dinner or turn to broaden the search. It's a computational mechanism, they say, that is similar to what drives hungry college students to a pizza.
