Biologists Produce Global Map of Plant Biodiversity
Biologists at the University of California, San Diego and the University of Bonn in Germany have produced a global map of estimated plant species richness. Covering several hundred thousand species, the scientists say their global map is the most extensive map of the distribution of biodiversity on... view more (2007-03-21)

ESA's Medspiration project branches out to support biodiversity
Maps of the sea surface temperature around Galapagos Islands and Cocos Island in the Pacific Ocean are being produced daily and are available online in full resolution in near-real time as part of the Medspiration project, an ESA-funded effort to represent the most reliable temperature of the seas... view more (2007-03-20)

Crops feel the heat as the world warms
Over a span of two decades, warming temperatures have caused annual losses of roughly $5 billion for major food crops, according to a new study by researchers at the Carnegie Institution and Lawrence Livermore National Laboratory.   view more (2007-03-16)

Biologists develop large gene dataset for rice plant
Scientists have reported development of a large dataset of gene sequences in rice. The information will lead to an increased understanding of how genes work in rice, an essential food for much of the world's population.   view more (2007-03-14)

Darwin's famous finches and Venter's marine microbes
Although the Galápagos finches were to play a pivotal role in the inception of Darwin's theory of evolution through natural selection, he had no inkling of their significance when he collected them during his voyage on the HMS Beagle.   view more (2007-03-14)

Global ocean sampling expedition
In three new metagenomic studies published online in the open-access journal PLoS Biology, Craig Venter and his team take advantage of the vast amount of microbial sequence data collected during their Sorcerer II Global Ocean Sampling (GOS) expedition to reveal an unprecedented level of genetic and... view more (2007-03-14)

Remote sheep population resists genetic drift
A whimsical attempt to establish a herd of mouflon for sport hunting on a remote island in the Indian Ocean 50 years ago has inadvertently created a laboratory for genetic researchers and led to a surprising discovery.   view more (2007-03-12)

Out of Africa-Bacteria, as well
When man made his way out of Africa some 60,000 years ago to populate the world, he was not alone: He was accompanied by the bacterium Helicobacter pylori, which causes gastritis in many people today.   view more (2007-02-15)

Researchers invent system to control and quarantine worms attacking computer networks
A new anti-worm technology developed by Penn State researchers can not only identify and contain worms milliseconds after a cyber attack, but can also release the information if the quarantine turns out to be unwarranted.   view more (2007-02-09)

Architectural plan revealed of doomsday arctic seed vault
The Norwegian government has revealed the architectural design for the Svalbard International Seed Vault, to be carved deep into frozen rock on an island not far from the North Pole.   view more (2007-02-09)

Female Antarctic seals give cold shoulder to local males
Female Antarctic fur seals will travel across a colony to actively seek males which are genetically diverse and unrelated, rather than mate with local dominant males.   view more (2007-02-08)

Something new under the Sun
That plants grow better if grown in a greenhouse in the correct climate is nothing new. Dutch researcher Rachel van Ooteghem has designed a control system for an improved solar greenhouse that yields more.   view more (2007-01-31)

ESA launches new project to protect biodiversity
The world's biodiversity is vanishing at an unprecedented rate - around 100 species every day - due to factors such as land use change and pollution.   view more (2007-01-10)

There's no scent like home
Tiny larval fish living among Australia's Great Barrier Reef spend the early days of their lives swept up in ocean currents that disperse them far from their places of birth.   view more (2007-01-09)

Two cosmic bursts upset tidy association between long gamma-ray bursts and supernovae
Two brilliant flashes of light from nearby galaxies are puzzling astronomers and could indicate that gamma-ray bursts, which signal the birth of a black hole, are more diverse than once thought.   view more (2006-12-21)

History-hunting geneticists can still follow familiar trail
As the world's first explorers branched away from humanity's birthplace in east Africa some 65,000 years ago, distinct mutations accumulated in the DNA of each population, essentially providing a genetic trail for modern researchers to follow.   view more (2006-12-20)

Pesticides need sunscreen to beat the heat
A pesticide with a new in-built sunscreen will help farmers beat the heat in crop protection. This means that the bug sprays last longer, as they are protected from the strong rays of sunshine, reports Chemistry & Industry, the magazine of the SCI.   view more (2006-12-18)

Mixed prairie grasses are better biofuel source, U of M study says
Highly diverse mixtures of native prairie plant species have emerged as a leader in the quest to identify the best source of biomass for producing sustainable, bio-based fuel to replace petroleum.   view more (2006-12-08)

NYU chemists create 'nanorobotic' arm to operate within DNA sequence
New York University chemistry professor Nadrian C. Seeman and his graduate student Baoquan Ding have developed a DNA cassette through which a nanomechanical device can be inserted and function within a DNA array, allowing for the motion of a nanorobotic arm.   view more (2006-12-08)

Theory of oscillations may explain biological mysteries
New mathematical studies of the interactions between oscillating biological populations may shed light on some of the toughest questions in ecology, including the number and types of species in an ecosystem, according to an article in the December 2006 issue of BioScience.   view more (2006-12-04)

Perennial wheat research looks at options for producers
Perennial wheat? The possibility is being looked at by a Texas Agricultural Experiment Station researcher.   view more (2006-11-29)

Dramatic shift from simple to complex marine ecosystems occurred 250M years ago at mass extinction
The earth experienced its biggest mass extinction about 250 million years ago, an event that wiped out an estimated 95% of marine species and 70% of land species. New research shows that this mass extinction did more than eliminate species: it fundamentally changed the basic ecology of the world's... view more (2006-11-27)

Wheat gene may boost foods' nutrient content
Researchers at the University of California, Davis; the U.S. Department of Agriculture; and the University of Haifa in Israel have cloned a gene from wild wheat that increases the protein, zinc and iron content in the grain, potentially offering a solution to nutritional deficiencies affecting... view more (2006-11-27)

Got cotton? Texas researchers' discovery could yield protein to feed millions
A scientific method used to explore cancer and HIV cures now has been successfully used by agricultural researchers in the quest to develop food for the world's hungry.   view more (2006-11-21)

New moth variety disarms plants guarded by selenium
In new work, researchers report that the ability of plants to defend themselves by accumulating high levels of a toxic element can be overcome by some insects, and that such adaptation potentially echoes in the food web as other predators and parasites may in turn evolve to deal with high levels of... view more (2006-11-21)
