New research indicates a 'troubled' greenhouse is brewing
...l issue of the journal Geology. In this case, the word "troubled" refers to the stormy conditions shown to have been in play during a well-known greenhouse event some 55 million years ago during the late Paleocene epoch. Retallack explored the relationship between seasonality and rainfall in soils, then ...GeneNotes - A novel information management software for biologists

In addition, the quality of computational results is far from perfect and requires nontrivial manual examination. The timely selection, integr...Turning viruses into allies against cancer
To most, the mere mention of the word "virus" stirs up memories of pain, fever and varying levels of suffering. But in recent years, scientists have been trying to turn these long-time medical foes into allies in the fight against cancer. Through genetic engineering, viruses are being r...The making and breaking of microtubules
...the microtubule grows. But through hydrolysis (the word means "water splitting"), GTP readily changes to a different nucleotide, guanosine diphosphate, or GDP. GDP-bound tubulin depolymerizes the microtubule by curling up protofilaments at its plus end and pulling it apart.

... into myelin-producing oligodendrocytes. "The key word here is 'combination.' This is one of a series of new studies showing that a combination of therapies is needed for successful spinal repair, in this case, specialized cells and growth factors. The experiments also used a combination of outcomes -- p...For first time, brain cells generated in a dish

Scientists in Steindler's lab noticed the similarities between primitive cell development in blood and in the brain in the late 1990s, calling the process "neuropoiesis." "The exciting part is we are actually using methods that r...From a Few Wild Ancestors, a Citrus Cornucopia
For most of us, the word “citrus?conjures up images of oranges, grapefruits, lemons, limes -- and possibly citrons or blood oranges, if you’re a true connoisseur of fruit. But for ARS horticulturalist Robert R. Krueger, the genus Citrus includes at least 16 species, with hu...Monkeys understand numbers across senses

And the question has been whether an animal without that kind of language based representation can still notice or represent these common...MIT researcher finds neuron growth in adult brain
...the cell: the dendrite. A dendrite, from the Greek word for tree, is a branched projection of a nerve cell that conducts electrical stimulation to the cell body. "We do see relatively large-scale growth" in the dendrites, Nedivi said.
