New genetic markers could improve early detection of drug-resistant tuberculosis

To many, tuberculosis (TB) may seem like a disease from a bygone era. But it still claims more than one million lives every year. And the problem is growing worse as Mycobacterium tuberculosisthe pathogen that causes TB, continues to evolve resistance to the antibiotics used to treat the disease. Now, researchers at San Diego State … Read more

What can chimpanzees tell us about cancer propensity in humans?

A recent study published in the renowned journal Cell Reports finds evidence for reduced functional activity of certain human cancer genes (such as breast cancer 2 gene or BRCA2), following the divergence from the chimpanzee-human last common ancestor. Study: Evidence for reduced BRCA2 functional activity in Homo sapiens after divergence from the chimpanzee-human last common … Read more

Researchers confirm the existence of a 36-mer cellulose synthase supercomplex in cotton fiber

About 180 billion tons of celluloses are produced by the world’s vegetation annually, making this polysaccharide the most abundant biological macromolecule on earth. It is produced predominantly by vascular plants, by a large number of algae and also by some bacteria, protists and tunicates. Cellulose microfibrils used for cell wall deposition are usually synthesized at … Read more
