Biology is the science focused on the investigation of the phenomenon of life—and of living organisms (and of such living systems as ecological systems). The term derives from the Greek: bios (meaning "life") and logia (meaning "study of").
Biologists study and communicate science-based information on the structure, functioning, growth, origin, evolution, distribution, and classification of these living organisms and systems.. Biology is composed of a wide spectrum of sub-disciplibes.

Changing Plant Characteristics to Make BiofuelsLast Updated on 2011-02-09 00:00:00
A Predictable Change
A new technique can change a
plant's characteristics to make biofuels.
A core objective of Oak Ridge National Laboratory's BioEnergy Science Center is to find ways to wring more energy out of the sugars stored in plants. In addition to developing better enzymes, improved microbes and more effective catalysts, Gerald Tuskan's team of plant biologists is exploring ways to generate more energy from biomass by "persuading" plants to store more sugar and then developing new methods of extracting these sugars.
Most of the sugar found in biomass is stored in plant cell walls as cellulose and hemicellulose. The biggest roadblock to extracting sugar from these cell wall polymers has been the difficulty of using biochemical tools to break down the walls. Tuskan, a scientist in ORNL's BioSciences Division, is working with a dozen Oak... More »
Marker, LaurieLast Updated on 2011-02-08 00:00:00Laurie Marker is a mammalian zoologist, most noted for her research with the Cheetah species. She is founder and Executive Director of the Cheetah Conservation Fund (CCF) with its headquarters in Namibia. Marker's groundbreaking research on the Cheetah species has included fundamental analysis on Cheetah genetics, morphology and behavior. Having worked with cheetahs since 1974, Marker established the not-for-profit CCF in 1990 and moved to Namibia to develop a permanent Conservation Research Centre for the wild cheetah. In 1992, CCF became a registered Namibian Trust. CCF’s groundbreaking activities are housed at their International Research and Education Centre in the main cheetah habitat of the country. In addition to fundamental research on the Cheetah species, Marker has developed innovative programs for conservation of the broader habitat that supports Cheetahs in Namibia;... More »
Eastwood, AliceLast Updated on 2011-02-07 00:00:00Alice Eastwood is considered an American botanist, although she was actually born in Canada. Eastwood was self educated and spent her entire professional life in the western USA. She was born in Toronto, Canada, in the year 1859. Moving to Colorado at the age of 14, she taught herself botany while working as a teacher. By 1890, Eastwood had moved to California, where she accepted a post at the herbarium of the California Academy of Sciences.
Besides prolific discoveries of new species, Eastwood can be counted as a heroine, from her climbing up in the burning building of the California Academy of Sciences to save the flora type specimen collection.
Eastwood had a productive career in describing new flora, stewarding the Academy's herbarium and in promoting the role of native flora in teaching youth. In 1892 she was appointed joint curator of the herbarium along with botanist Mary... More »
Life from the Skies?Last Updated on 2011-02-06 00:00:00
?Main Image Explanation: What's that behind Titan? It's another of Saturn's moons: Tethys. The robotic Cassini spacecraft orbiting Saturn captured the heavily cratered Tethys slipping behind Saturn's atmosphere-shrouded Titan late last year. The largest crater on Tethys, Odysseus, is easily visible on the distant moon. Titan shows not only its thick and opaque orange lower atmosphere, but also an unusual upper layer of blue-tinted haze. Tethys, at about 2 million kilometers distant, was twice as far from Cassini as was Titan when the above image was taken. In 2004, Cassini released the Hyugens probe which landed on Titan and provided humanity's first views of the surface of the Solar System's only known lake-bearing moon.
