Fundamental Building Block In Flowering Plants Evolved Independently, Yet Almost Identically In Ancient Plants

Biologists have discovered that a fundamental building block in the cells of flowering plants evolved independently, yet almost identically, on a separate branch of the evolutionary tree--in an ancient plant group called lycophytes that originated at least 420 million years ago.

Measuring Stress In Plants To Select Best Species For Reforestation

Plants undergo stress because of lack of water, due to the heat or the cold or to excess of light. A research team from the University of the Basque Country have analysed the substances that are triggered in plants to protect themselves, with the goal of choosing the species that is best suited to the environment during reforestation under adverse environmental conditions.

Power Plants Open to Hack Attack

The software power plants use to automate their operations contains a vulnerability hackers could exploit to crash the system, reports New Scientist.

Auditors: Nuclear plants not following fire rules

Operators of nuclear power plants have yet to comply with some of the government's fire safety rules three decades after they were issued, a congressional report said Monday.

Reforestation of exotic plants can disturb soil fertility

Washington, May 30: Scientists have determined that the reforestation of some exotic plants can surprisingly disturb the fertility of tropical soils.

Fungus That Produces Biofuels From Plants: Genome Sequenced

The fungus Trichoderma reesei optimally breaks down plants into simple sugars, the basic components of ethanol. The fungus's genome has recently been sequenced by researchers from the Architecture et fonction des macromolécules biologiques laboratory (CNRS/Université de la Méditerranée and Universite de Provence), working together with an American team. The results show that only a few genes are responsible for the fungus's enzymatic activity. They offer new avenues for the fabrication of second generation biofuels from plant waste.

Vices of the week: Cyborg plants get Tasered

One of the coolest stories we got wind of this week was Ryan Wolfe's bionic plants. Generating their own light, they can grow in total darkness. Now they only need to figure out how to water themselves and they'll be able to get rid of us. Wolfe's creations took a back seat to the story about how Taser is planning to mount video cameras on future stunguns. Don't film me, bro!

Science in Society #38 Summer 2008 - Letters to the Editor

(SiS 27) and Message from Andra Predesh:Return to organic cotton & avoid the Bt cotton trap (SiS 29), I enclose photographs of mealy bugs infested cotton plants in the demonstration plots of different seed companies in Vidarbha: Ganga Kavari, Paras Bbhrahma, and Banny. All of the plots have the Bollgard label. These mealy bugs have never been in our region on any plants before Bt cotton was introduced. I learned about the devastation of cotton in China two years ago. This alerted me to photograph and video the demonstration plots regularly. So, anybody can say with confidence now that the mealy bug has entered Vidarbha cotton fields through the Bt cottonseed.

Climate change does double-whammy to animals in seasonal environments

Plant-eating animals in highly seasonal environments, such as the Arctic, are struggling to locate nutritious food as a result of climate change, according to research that will be published in the 21 May 2008 online edition of the journal Proceedings of the Royal Society B. Led by Penn State Associate Professor of Biology Eric Post, the research, which focused on caribou, suggests that not only are these animals arriving at their breeding grounds too late in the season to enjoy the peak availability of food--the focus of previous research by Post--but they also are suffering from a reduced ability to locate the few high-quality plants that remain before these plants, too, become unavailable, according to Eurekalert, the news service of the American Association for the Advancement of Science.

Mexico plants nine million trees in one day: minister

The day of tree-planting took place on Saturday and aimed to compensate for the 316,000 hectares (780,000 acres) of forest that are lost annually to illegal exploitation, Environment Minister Juan Elvira said.

Rare Plants And Endangered Species Such As Tigers At Risk From Traditional Medicine

Two reports from TRAFFIC, the world's largest wildlife trade monitoring network, on traditional medicine systems in Cambodia and Vietnam suggest that illegal wildlife trade, including entire tiger skeletons, and unsustainable harvesting is depleting the region's rich and varied biodiversity and putting the primary healthcare resource of millions at risk.
