A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology (NIST) has set a new record for stability. The clocks act like 21st-century pendulums or metronomes that could swing back and forth with perfect timing for a period comparable to the age of the universe.

By determining the three-dimensional structure of proteins at the atomic level, researchers at the National Institutes of Health have discovered how some commonly used flame retardants, called brominated flame retardants (BFRs), can mimic estrogen hormones and possibly disrupt the body’s endocrine system. BFRs are chemicals added or applied to materials to slow or prevent the start or growth of fire.

30 years after the invention of PCR, a reverse process of PCR, removing PCR (R-PCR), has been developed which can eliminate undesired DNA fragments, cycle by cycle. If researchers want to amplify their desired genes, they can use PCR, whereas, if researchers want to remove their undesired genes, they can use this new technique, R-PCR.
