Pushing them out: Snake ancestor likely gave birth to live young
The ancestor of snakes and lizards likely gave birth to live young, rather than laid eggs, and over time species have switched back and...
Cause of genetic disorder found in ‘dark matter’ of DNA
For the first time, scientists have used new technology which analyses the whole genome to find the cause of a genetic disease in what...
A pea-shooter for molecules: Nanopores can slow throughput
Like a pea going through a straw, tiny molecules can pass through microscopic cylinders known as nanotubes. This could potentially be used to select...
Speedy tests cut wait time for drug-resistant TB patients
Barcelona, Spain: Results of a new study suggest that three new diagnostic tests could each be used to successfully diagnose drug resistance in tuberculosis...
Genome sequencing work illuminates microbial dark matter
The immense, invisible world of the earth’s microbial life is being illuminated by an extensive project to sequence the genomes of microbes at the...
Evolution reveals missing link between DNA and protein shape
Fifty years after the pioneering discovery that a protein's three-dimensional structure is determined solely by the sequence of its amino acids, an international team of researchers has taken a major step toward fulfilling the tantaliz...
Noninvasive test for trisomy 21 closer at hand
St. Louis, MO, February 10, 2011 -- In 1980 in the United States, approximately 4.5% of all pregnant women were of advanced maternal age. By 2007 that figure had increased to 14%. Women over 35 are at increased risk of giving birth to babies with t...
