For carnivorous plants, slow but steady wins the race
Like the man-eating plant in Little Shop of Horrors, carnivorous plants rely on animal prey for sustenance. Fortunately for humans, carnivorous plants found in nature are not dependent on a diet of human blood but rather are satisfied with the occasional fly or other insect. view more (2009-09-15)
Microbe has huge role in ocean life, carbon cycle
Researchers at Oregon State University and Diversa Corporation have discovered that the smallest free-living cell known also has the smallest genome, or genetic structure, of any independent cell-and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge role in the cycling of carbon on Earth. view more (2005-08-19)
APL regulates vascular tissue identity in Arabidopsis
Plants have a conductive tissue, phloem, for transporting sugars and hormones to non-green parts after photosynthesis. Phloem has two basic cell types, enucleate sieve elements (SE) and companion cells (CC). Scientists from the University of Helsinki have developmentally analyzed the process of phloem development in Arabidopsis plant and... view more... (2003-11-13)
Great Lake's sinkholes host exotic ecosystems
Researchers are exploring extreme conditions for life in a place not known for extremes. As little as 20 meters (66 feet) below the surface of Lake Huron, the third largest of North America's Great Lakes, peculiar geological formations-sinkholes made by water dissolving parts of an ancient underlying seabed-harbor bizarre ecosystems where the fish... view more...

Flowers to Order
How do growers ensure their Poinsettias are ready for Christmas or their roses for Valentine’s Day? Professor Andrew Millar (Warwick University) will present current work on Thursday 3 April (in session P9.9) which could help breeders to schedule their crops more accurately. Like most organisms, plants possess a ‘clock’ which... view more... (2003-03-31)
Simplest circadian clocks operate via orderly phosphate transfers
Researchers at Harvard University and the Howard Hughes Medical Institute have found that a simple circadian clock found in some bacteria operates by the rhythmic addition and subtraction of phosphate groups at two key locations on a single protein. view more (2007-10-05)
Orientation of antenna protein in photosynthetic bacteria described
Researchers at Washington University in St. Louis have figured out the orientation of a protein in the antenna complex to its neighboring membrane in a photosynthetic bacterium, a key find in the process of energy transfer in photosynthesis. view more (2009-04-03)
Study unravels why certain fishes went extinct 65 million years ago
Large size and a fast bite spelled doom for bony fishes during the last mass extinction 65 million years ago, according to a new study to be published March 31, 2009, in the Proceedings of the National Academy of Sciences. view more (2009-03-27)
Alien plants attack using 'resource conservation' as weapon, researchers say
One of the most serious and least understood threats to the world's ecosystems is the problem of invasive species-exotic plants, animals and other organisms that are brought into habitats and subsequently spread at a rapid rate, often replacing native species and reducing biodiversity. view more (2007-05-02)
Bacterium sequenced makes rare form of chlorophyll
Researchers at Washington University in St. Louis and Arizona State University have sequenced the genome of a rare bacterium that harvests light energy by making an even rarer form of chlorophyll, chlorophyll d. Chlorophyll d absorbs "red edge," near infrared, long wave length light, invisible to the naked eye. view more (2008-02-05)
New tool probes function of rice genes
A new tool for investigating the rice genome has been developed by researchers at UC Davis led by Pamela Ronald, professor of plant pathology. view more (2008-10-09)
Model gives clearer idea of how oxygen came to dominate Earth's atmosphere
A number of hypotheses have been used to explain how free oxygen first accumulated in Earth's atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. view more (2005-08-09)
Food-crop yields in future greenhouse-gas conditions lower than expected
Open-air field trials involving five major food crops grown under carbon-dioxide levels projected for the future are harvesting dramatically less bounty than those raised in earlier greenhouse and other enclosed test conditions — and scientists warn that global food supplies could be at risk without changes in production strategies. view more (2006-06-30)
Scientists learning to create nanomaterials based on micro-algae patterns
Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory. view more (2006-12-07)
Toward home-brewed electricity with 'personalized solar energy'
New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities. view more (2009-11-05)
NASA research reveals climate warming reduces ocean food supply
In a NASA study, scientists have concluded that when Earth's climate warms, there is a reduction in the ocean's primary food supply. This poses a potential threat to fisheries and ecosystems. view more (2006-12-07)
New group of algae discovered: Picobiliphytes
An international group of researchers has succeeded in identifying a previously unknown group of algae. As currently reported in the scientific journal Science, the newly discovered algae are found among the smallest members of photosynthetic plankton-the picoplankton ('Picobiliphytes: A marine picoplanktonic algal group with unknown affinities to... view more...

Microbes use sunscreens too
Microbes can withstand extreme levels of atmospheric ultraviolet light (UV) by producing their own sunscreens. Unlike humans, some bugs may even be able to survive without any help from the ozone layer scientists heard today (Thursday 19 September) at the Society for General Microbiology autumn meeting at Loughborough University. "A group of... view more... (2002-08-28)
Hybrid grass may prove to be valuable fuel source
Giant Miscanthus (Miscanthus x giganteus), a hybrid grass that can grow 13 feet high, may be a valuable renewable fuel source for the future. view more (2005-09-28)
Early exposure to common weed killer impairs amphibian development
Tadpoles develop deformed hearts and impaired kidneys and digestive systems when exposed to the widely used herbicide atrazine in their early stages of life, according to research by Tufts University biologists. view more (2008-04-16)
