DNA traces evolution of extinct sabertooths and the American cheetah-like cat
By performing sequence analysis of ancient DNA, a team of researchers has obtained data that help clarify our view of the evolutionary relationships shared by the large predatory cats that once roamed the prehistoric New World. The work is reported in the August 9 issue of Current Biology by Ross Barnett of the University of Oxford and a team of researchers from Britain, the United States,...A new portable biosensor detects traces of contaminants in food more quickly and cheaply
Scientists at the Universitat Autònoma de Barcelona (UAB), in cooperation with the CSIC, have developed a new electro-chemical biosensor which detects the presence, in food, of very small amounts of atrazine –one of the most widely used herbicides in agriculture and which also has very long lasting effects on the environment- as well as antibiotics in food. The biosensor is faster, more portable...Ancient DNA traces the woolly mammoth's disappearance
DNA lifted from the bones, teeth, and tusks of the extinct mammoths revealed a “genetic signature” of a range expansion after the...Old memory traces in brain may trigger chronic pain
A Northwestern University researcher has found a key source of chronic pain...Metal traces in infant formula cans responsible for recall.
The infant formula Gentlease is being recalled from the market as stated by the FDA due to presence of presence of metal particles in some cans. // So this brand would not be sold in markets in US. The makers of Gentlease powdered infant formula, Mead Johnson Nutritionals of EVANSVILLE, Indiana, initiated the voluntary recall of 24-ounce cans with batch number BMJ19 printed on the bott...
