Paxillin either slides along the actin filaments or is pulled by them. In a surprise, Chien and Hu also showed that paxillin itself forms long, fibrous structures ...

Researchers discover inherited mutation for leukemia

...itary predisposition. However, usually only two or three people within a family are affected, making it difficult to do the genetic studies needed to find possible mutations, Plass says. The family examined in this research was identified by collaborator Henry Lynch at Creighton University. The res...

Soils offer new hope as carbon sink

...esidue, mulch and compost is likely to last two or three years, while stable carbon like agrichar will last up to hundreds of years. "This is significant for farmer costs because one application of agrichar may be the equivalent of compost applications of the same weight every year for decades. "For ...

Researchers find 24 species believed new to science in Suriname rainforest

... rainforest on the planet, a northern Amazon tract three times larger than the U.S. state of Texas (twice the size of Ethiopia) that is home to 100 indigenous groups. In Suriname, the only former Dutch colony in South America, the forests are at risk from foreign logging and other resource extraction. ...

Research team identifies new Alzheimer's gene

...a form of the GAB2 gene and Alzheimer’s disease in three separate groups, the researchers showed that the GAB2 gene is unusually active in vulnerable brain cells from Alzheimer’s patients and that the GAB2 protein produced by this gene is present in those brain cells containing tangles. When the researcher...
