DNA origami surpasses important thresholds

Using a technique known as DNA origami, biophysicist Hendrik Dietz has been building nanometer-scale objects for several years at the Technical University of Munich (TUM). Now, Dietz and his team have not only broken out ...

DNA damage repair—molecular insights

The first line of defense against skin cancer is the ability to repair DNA damage caused by UV light. The XPA protein plays an important role in the repair of certain DNA damage, and mutations in this protein have been implicated ...

Polyproline protects cell monolayers from freeze damage

Nature has evolved sugars, amino acids, and special antifreeze proteins as cryoprotectants. People use organic solvents and synthetic polymers as additives to prevent cell cultures from freezing damage. Now, English scientists ...

A crucial enzyme unveiled at last

After 40 years of research, researchers at the CEA, CNRS, University Grenoble-Alps, University of Montpellier and Inserm have finally identified the enzyme responsible for the tubulin detyrosination. Surprisingly, it is not ...

Risk-free gene reactivation

Chemical modification of DNA subunits contribute to the regulation of gene expression. Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have now deciphered a new pathway can reactivate genes that have been ...

Computer analysis fills gaps in antibody blueprint

Antibodies defend our bodies against intruders. These molecules consist of proteins with attached sugars. However, the blueprint directing the processing of these sugars on the protein was not well understood until now. In ...

Biologists taught infusoria to fight poisons

A team of scientists from Lomonosov Moscow State University and the Russian Academy of Sciences has found a new substance with antioxidant properties able to protect living organisms from toxic compounds. The results of the ...

Researchers discover neurotoxin in Lake Winnipeg

A new study from UBC's Okanagan campus has found that BMAA—a toxin linked to several neurodegenerative diseases—is present in high concentrations during cyanobacteria blooms in Lake Winnipeg.

Biology and chemistry combine to generate new antibiotics

Combining the innovations of synthetic biology with biology and chemistry, a team of scientists at the University of Bristol have generated a brand-new platform that will allow the production of desperately needed brand-new ...
