Study shows that parasites form the thread of food webs
Scientists have discovered that parasites are suprisingly important in food webs and their findings appear in a report published this week in the Early Edition of the on-line version of the Proceedings of the National Academy of Sciences.   view more (2006-07-13)

Surprising Killer of Southeastern Salt Marshes: Common Sea Snails
Periwinkles, the spiral-shelled snails commonly found along rocky U.S. shorelines, play a primary role in the unprecedented disappearance of salt marsh in the southeastern states, according to new research published in Science.   view more (2005-12-16)

Inside rocks, implications for finding life on Mars
If a future space mission to Mars brings rocks back to Earth, Schopf said the techniques he has used, called confocal laser scanning microscopy and Raman spectroscopy, could enable scientists to look at microscopic fossils inside the rocks to search for signs of life, such as organic cell walls.   view more (2006-02-01)

Dissapearing arctic lakes linked to climate change
Continued arctic warming may be causing a decrease in the number and size of Arctic lakes. The issue is the subject of a paper published in the June 3 issue of the journal "Science." The paper, titled, "Disappearing Arctic Lakes" is the result of a comparison of satellite data taken of Siberia in the early 1970s to data from... view more... (2005-06-06)

Marine snail's neural network sheds light on the basis for flexible behavior
By studying how a relatively simple motor network of the marine snail Aplysia produces variants of a particular feeding behavior, researchers have found that the ability to generate a large number of behavioral variants stems from the elegant hierarchical architecture of the brain's motor network.   view more (2005-10-11)

Magnetic misfits: South seeking bacteria in the Northern Hemisphere
Magnetotactic bacteria contain chains of magnetic iron minerals that allow them to orient in the earth's magnetic field much like living compass needles.   view more (2006-01-23)

Molecular pathway linked to breast cancer recurrence
A study published in the September issue of Cancer Cell provides new evidence for a genetic pathway that is involved in the recurrence of breast cancer and identifies a potential target for development of new anticancer therapeutics.   view more (2005-09-20)

Natural compound from 'pond scum' shows potential activity against Alzheimer's
A compound isolated from a cyanobacterium, a type of blue-green algae known as Nostoc, shows promise of becoming a natural drug candidate for fighting Alzheimer's and other neurodegenerative diseases.   view more (2005-12-29)

A new tool against brain disease
University of Utah researchers isolated an unusual nerve toxin in an ocean-dwelling snail, and say its ability to glom onto the brain's nicotine receptors may be useful for designing new drugs to treat a variety of psychiatric and brain diseases.   view more (2006-08-21)

DNA barcodes put to the test
With species around the world disappearing faster than biologists can identify them, many scientists pinned their hopes on DNA barcoding, a recently proposed strategy that treats a short fragment of DNA as a sort of universal product code to identify species.   view more (2005-11-29)

MTBE contamination: A microbial approach for groundwater
Max Häggblom's Rutgers laboratory has taken an important step on the path to using microbes to rid the environment of methyl tertiary-butyl ether (MTBE), a toxic gasoline additive now classified as a potential human carcinogen.   view more (2006-03-22)

Ponds found to take up carbon like world's oceans
Research led by Iowa State University limnologist, or lake scientist, John Downing finds that ponds around the globe could absorb as much carbon as the world's oceans.   view more (2008-05-08)

Penn researchers discover a molecular pathway that leads to recurrence of breast cancer
(Philadelphia, PA)-Using a recently developed mouse model of breast cancer, a team from the University of Pennsylvania School of Medicine has shown that Snail, a molecule normally important in embryonic development, can promote breast cancer recurrence.   view more (2005-09-20)

Hubble sees dark matter ring in a galaxy cluster
A team of astronomers used the Hubble Space Telescope to find the best evidence yet for the existence of dark matter, present in the form of a ghostly ring in a galaxy cluster.   view more (2007-05-17)

Paramecia Adapt Their Swimming to Changing Gravitational Force
For many single-celled organisms living in water, the force is always against them. The classic example is the slipper-shaped paramecium, which consistently swims harder going up than going down, just to keep from sinking.   view more (2006-09-19)

Hubble finds ring of dark matter

Leptin found to control appetite and limb development in frogs
Leptin, the hormone secreted by fat cells that plays an important role in food intake, has been described for the first time in a cold-blooded vertebrate, the South African clawed frog Xenopus.   view more (2006-06-13)

NASA's robotic sub readies for dive into Earth's deepest sinkhole
An underwater robot, shaped like a flattened orange, maneuvered untethered and autonomously within a 115-meter-deep sinkhole during tests this month in Mexico, a prelude to its mission to probe the mysterious nether reaches of the world's deepest sinkhole.   view more (2007-03-01)
