Zika's shape-shifting machinery, and a possible vulnerability      (via sciencedaily.com)     Original source 

Viruses have limited genetic material -- and few proteins -- so all the pieces must work extra hard. Zika is a great example; the virus only produces 10 proteins. Now researchers have shown how the virus does so much with so little and may have identified a therapeutic vulnerability.

New genes can arise from nothing      (via sciencedaily.com)     Original source 

The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes.

Molecular fossils shed light on ancient life      (via sciencedaily.com)     Original source 

Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.

Fungus-fighting protein could help overcome severe autoimmune disease and cancer      (via sciencedaily.com)     Original source 

A protein in the immune system programmed to protect the body from fungal infections is also responsible for exacerbating the severity of certain autoimmune diseases such as irritable bowel disease (IBS), type 1 diabetes, eczema and other chronic disorders, new research has found.  The discovery could pave the way for new and more effective drugs, without the nasty side effects of existing treatments. In addition to helping to manage severe autoimmune conditions, the breakthrough could also help treat all types of cancer.

Sugar permeation discovered in plant aquaporins      (via sciencedaily.com)     Original source 

Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.

Recycling concrete using carbon can reduce emissions and waste      (via sciencedaily.com)     Original source 

Amid the rubble of large-sale earthquake, war or other disaster -- and as ageing buildings and infrastructure are replaced -- mountains of concrete are often taken to landfill or pounded into rubble for roads. For a more sustainable approach, experts are developing a 'value add' for old broken concrete to 'upcycling' coarse aggregate to produce a strong, durable and workable concrete using a small amount of a secret ingredient -- graphene.

Macrophages 'eat' insulin-producing cells to regulate insulin after mice have given birth      (via sciencedaily.com)     Original source 

Pregnancy brings a rise in pancreatic beta cells -- the cells that produce insulin. Shortly after birth, these cells return to their normal levels. The mechanisms behind this process had remained a mystery. But now a research group has revealed that white blood cells called macrophages 'eat' these cells.

Researchers have cracked the cellular code on protein folding, offering hope for new therapeutic avenues for many diseases      (via sciencedaily.com)     Original source 

While we often think of diseases as caused by foreign bodies -- bacteria or viruses -- there are hundreds of diseases affecting humans that result from errors in cellular production of its proteins. A team of researchers recently leveraged the power of cutting-edge technology, including an innovative technique called glycoproteomics, to unlock the carbohydrate-based code that governs how certain classes of proteins form themselves into the complex shapes necessary to keep us healthy.
