Scientists use light to 'tag and track' genetic processes

(Phys.org) -- In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material ...

Seeking a splice for better rice

Every organism produces a staggering variety of molecules, each with its own particular biological function. Complex interplay between genetic and environmental factors determines the production levels for each compound. ...

Accelerating cellular assembly lines

The immune system generates antibodies to mark threats that need to be eliminated, and these protein complexes bind their targets with remarkable strength and selectivity. Scientists have learned how to generate cell lines ...

Researchers explain mechanism that helps viruses spread

In an article published in the scientific journal Nature, a University of Colorado School of Medicine researcher and colleagues explain how RNA molecules found in certain viruses mimic the shape of other molecules as part ...

New sensor measures calcium concentrations deep inside tissue

Key processes in the body are controlled by the concentration of calcium in and around cells. A team from the Technical University of Munich (TUM) and the Helmholtz Zentrum München have developed the first sensor molecule ...

An unexpected attraction between nucleic acids and fat

All cells on Earth are enveloped in a fatty layer of lipids. Lipid membranes protect the content of the cells, including genetic information such as RNA and DNA. A new study from the researchers at the B CUBE—Center for ...

New tool isolates RNA within specific cells (w/Video)

A team of University of Oregon biologists, using fruit flies, has created a way to isolate RNA from specific cells, opening a new window on how gene expression drives normal development and disease-causing breakdowns.

How cells optimize the functioning of their power plants

Mitochondria, which are probably derived from distant bacterial ancestors incorporated into our cells, have their own DNA. However, we know little about how these organelles, which convert oxygen and consumed nutrients into ...

How E. coli defends itself against antibiotics

Imagine that you have a very sore throat. You're sick, your throat hurts, and a visit to the doctor confirms that the pain is due to a bacterial infection. You get a prescription for antibiotics, which quickly sorts out your ...
