Measuring molecules with the naked eye

When someone develops liver cancer, the disease introduces a very subtle difference to their bloodstream, increasing the concentration of a particular molecule by just 10 parts per billion.

Smallest, fastest-known RNA switches provide new drug targets

(Phys.org)—A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting ...

Engineers collaborate on inexpensive DNA sequencing method

(Phys.org)—Rapid, accurate genetic sequencing soon may be within reach of every doctor's office if recent research from the National Institute of Standards and Technology (NIST) and Columbia University's School of Engineering ...

Life's first taste of phosphorus

Despite its impressive biological resume, phosphorus is relatively inaccessible as elements go. To understand how phosphorus obtained its prominent role, scientists are modeling the early geochemical environment on Earth ...

Molecular code cracked

(Phys.org) -- Scientists have cracked a molecular code that may open the way to destroying or correcting defective gene products, such as those that cause genetic disorders in humans.
