Cornell researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes ...

New method to predict the risk of adverse drug events

Studying signaling within cells can predict the risk of adverse drug reactions of novel obesity and type II diabetes treatments before they reach the patient, according to a new study from Karolinska Institutet published ...

Split gene-editing tool offers greater precision

To make a gene-editing tool more precise and easier to control, Rice University engineers split it into two pieces that only come back together when a third small molecule is added.

Mature sperm lack intact mitochondrial DNA, study finds

New research provides insight about the bedrock scientific principle that mitochondrial DNA—the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body—is exclusively passed ...

Capturing the chemistry of radium-223 for cancer treatment

Scientists need a better understanding of the chemistry of radium to be able to target the isotope radium-223 (Ra-223) to cancer cells. Once delivered, Ra-223 can destroy those cells with alpha particles, a type of radiation.

How a pathogenic bacterium searches for food

Bacteria whirl around in the mouths of most people, forming dental plaques and sometimes causing nasty gum infections. Treponema denticola might be a dangerous pathogen, but not much is known about this bacterium. It was ...
