High tech detectives screen thousands of genes, proteins to solve puzzle of lung disease
...xposed to asbestos. Best of all, the marker can be detected with a blood test. Another scientist, Jan Schnitzer of the Sidney Kimmel Cancer Center in San Diego, has developed a technique that allows the study of key genes and proteins of the lung's blood vessels without removing them from the lung, Pitt sai...Gene linked to autism in families with more than one affected child

If one identical twin has it, so will the other in nearly 9 out of 10 cases. If one sibling has the disorder, the other siblings run a 35-fold greater-than...Biofuel cells without the bio cells

This method is so sensitive that scientists can use it to detect whether a DNA strand has been shortened by as little as one base pair in length, which opens the door for mapping the exact location of protein-DNA interactions. ...Children of allergy sufferers prone to same problem

The DESI procedure does this by positively charging water molecules by spraying a stream of water in the presence of an electric field. These charged molecules contain an extra proton and are called ions. When the charged water droplets...NHGRI aims to make DNA sequencing faster, more cost effective
