Computer scientists scale 'layer 2' data center networks to 100,000 ports and beyond
University of California, San Diego computer scientists have created software that they hope will lead to data centers that logically function as single, plug-and-play networks that will scale to the massive scale of modern data center networks. view more (2009-08-18)
Nocturnal dialysis improves heart disease in patients with end-stage kidney failure
Night-time hemodialysis patients may have a greater capacity to repair their hearts and blood vessels compared to those on conventional dialysis three times a week. view more (2005-10-03)
Oregon researchers discover a mechanism leading to cleft palate
By creating a genetic mutation in zebrafish, University of Oregon scientists say they've discovered a previously unknown mechanism for cleft palate, a common birth defect in humans that has challenged medical professionals for centuries. view more (2008-02-12)
MIT bioengineer advances survival, promise of adult stem cells
MIT researchers have developed a technique to encourage the survival and growth of adult stem cells, a step that could help realize the therapeutic potential of such cells. view more (2007-02-28)
Study of guanacos launched in Chile
The Wildlife Conservation Society has launched a study in Chile's Karukinka reserve on Tierra del Fuego to help protect the guanaco - a wild cousin of the llama that once roamed in vast herds from the Andean Plateau to the steppes of Patagonia. view more (2008-06-11)
Paradigm shift: Switch for programmed cell death promotes spread of glioblastoma
Malignant tumors have usually lost their ability to destroy themselves by programmed cell death, or apoptosis. Therefore, tumors are often resistant to chemotherapy or radiation therapy, whose effect is based on forcing tumor cells to commit suicide. view more (2008-03-12)
Birds carry bacteria across the hemispheres: Migratory birds transmit borreliosis
Migrating birds transmit different forms of the Borrelia bacterium or Borrelia spirochetes to every corner of the globe. Birds are especially prone to Borrelia infected ticks during their autumn and spring migrations. The bacteria may also persist for several months in the birds and it may then be reactivated in response to migration. Borrelia... view more... (2005-05-20)
Juvenile bluefin tunas can dive to depths of more than 1000 meters
A bluefin tuna, tagged by AZTI-Tecnalia in August 2008, 15 miles to the north of Donostia-San Sebastián, was caught on 15 August of this year by a pleasure craft 88 miles north of Bakio. view more (2009-09-30)
Polarization holographic device using photoreactive polymer liquid crystals
Photo-control of molecular orientation of polymer materials is of great interest for the development of highly functionalized holographic optical devices. view more (2005-10-19)
Tiny Clue Reveals New Path Toward Heart Disease
Geneticists have discovered a new gene that may put individuals at higher risk of developing cardiovascular disease. view more (2007-03-23)
Tachographs for diving animals
Seals, sea lions and penguins have two things in common with whales and dolphins: They are all ocean swimmers and evoke human sympathy - not only from children. Especially when whales become stranded or seals fall victim to an epidemic, some of us ask: How did this happen? Could this be prevented in future? The job of answering such questions lies... view more... (2002-12-20)
Protein's New Role Discovered in Autoimmune Disease
Investigators at the University of Alabama at Birmingham (UAB) have identified the previously unknown role of a chemical 'messenger' leading to autoimmune disorders like rheumatoid arthritis and lupus. view more (2008-01-03)
Want to monitor climate change? P-p-p-pick up a penguin!
We are used to hearing about the effects of climate change in terms of unusual animal behaviour, such as altering patterns of fish and bird migration. view more (2007-04-04)
Weizmann Institute scientists discover a control mechanism for metastasis
Metastasis - when cancer cells dissociate from the original tumor and migrate via the blood stream to colonize distant organs - is the main cause of cancer death. view more (2007-08-08)
Ancestors of African Pygmies and neighboring farmers separated around 60,000 years ago
All African Pygmies, inhabiting a large territory extending west-to-east along Central Africa, descend from a unique population who lived around 20,000 years ago, according to an international study led by researchers at the Institut Pasteur in Paris. view more (2009-04-10)
Drawing a crowd: How progenitor cells are recruited to tumor blood vessels from the bone marrow
Cells within the bone marrow (progenitor cells) that express a protein called CD34 have been shown to leave the marrow and travel to sites of tissue injury to mediate repair. view more (2006-02-24)
Genetic Heterogeneity of Icelanders
Research undertaken by Professor Einar 'rnason at the University of Iceland, Reykjavik and published in the January 2003 issue of Annals of Human Genetics highlights the inaccuracy of claims that Icelanders are a 'genetically homogenous' population. Professor 'rnason explains in his article: "Recently, statements have been made about a... view more... (2003-02-07)
Markers of brain cell development may help success of stem cell transplants
Four sugar-coated faces made by stem cells as they differentiate into brain cells during development have been identified by scientists. view more (2005-09-07)
Making more efficient fuel cells
Bacteria that generate significant amounts of electricity could be used in microbial fuel cells to provide power in remote environments or to convert waste to electricity. view more (2009-09-08)
When cancer cells can't let go
Like a climber scaling a rock face, a migrating cancer cell has to keep a tight grip on the surface but also let go at the right moment to move ahead. view more (2009-04-14)
