Rearranging the cell’s skeleton

Cell biologists at Johns Hopkins have identified key steps in how certain molecules alter a cell’s skeletal shape and drive the cell’s movement. Results of their research, published in the December 13 issue of Science Signaling, have implications for figuring out what triggers the metastatic spread of cancer cells and wound-healing. “Essentially we are figuring out how cells crawl,” says Takanari Inoue, Ph.D., an assistant professor of cell biology and member of the Center for Cell Dynamics in the Johns Hopkins … Continue reading

There is no such thing as a Brontosaurus!

Thanks to Phil Krause Othniel Charles Marsh, a Professor of Paleontology at Yale University, described and named an incomplete (and juvenile) skeleton of Apatosaurus ajax in 1877. Two years later, Marsh announced the discovery of a larger and more complete specimen at Como Bluff Wyoming—which, because of discrepancies including the size difference, Marsh incorrectly identified as belonging to an entirely new genus and species. He dubbed the new species Brontosaurus excelsus, meaning “thunder lizard”, from the Greek brontē meaning ‘thunder’ … Continue reading

Mini Robot to Remove Stomach Cancer

Researchers of Singapore have come up with a novel idea to remove cancer from the body of a victim. It has been informed that a crab shaped robot has been created which is small in size but of great use. The robot can enter the gut of the victim through endoscope and thus can remove the tumor. The robot has been equipped with pincer and hook which helps it in removing the cancer tumor. This technique would not leave back any … Continue reading

The first land plants pretty much ruined the entire planet

The first, moss-like plants emerged on land about 470 million years ago. In just 25 million years, they stripped the planet of vital minerals, wrecked Earth’s carbon cycle, started an ice age, and caused a mass extinction of marine life. That’s the finding of researchers at Oxford and the University of Exeter, who set out to figure just what role the first terrestrial plants had on Earth when they emerged in the Ordovician Period. Previous research into this time revealed … Continue reading

A spider web’s strength lies in more than its silk

While researchers have long known of the incredible strength of spider silk, the robust nature of the tiny filaments cannot alone explain how webs survive multiple tears and winds that exceed hurricane strength. Now, a study that combines experimental observations of spider webs with complex computer simulations has shown that web durability depends not only on silk strength, but on how the overall web design compensates for damage and the response of individual strands to continuously varying stresses. Reporting in the … Continue reading
