The ancient armor of fish -- scales -- provide clues to hair, feather development
How do scale patterns on fish provide understanding of the development of feathers, fur -- and even cancer? Biologists are investigating.

Variations of a single gene drive diverse pigeon feather patterns
Biologists have discovered that different versions of a single gene, called NDP (Norrie Disease Protein), have unexpected links between color patterns in pigeons, and vision defects in humans. These gene variations were likely bred into pigeons by humans from a different pigeon species and are now evolutionarily advantageous in wild populations of feral pigeons living in urban environments.

Impact of temperature on mitochondrial DNA evolution
A new study provides evidence towards selection in mtDNA due to variations in temperature.

The depths of the ocean and gut flora unravel the mystery of microbial genes
Surprisingly, the functions of a huge number of microbial genes are still unknown. This knowledge gap can be thought of as ''genomic dark matter'' in microbes, and neither computational biology nor current lab techniques have been able address this gap. This challenge has now been tackled through an international collaboration between the Institute for Research in Biomedicine (IRB Barcelona) and two other interdisciplinary research centres, namely the IJS in Ljubljana (Slovenia) and RBI in Zagreb (Croatia).

Thawing permafrost microbiomes fuel climate change
A new study could lead to more accurate predictions or the rate of global warming from greenhouse gas emissions produced by thawing permafrost in the next 100 years. The study of the microorganisms involved in permafrost carbon degradation links changing microbial communities and biogeochemistry to the rise of greenhouse gas emissions.

Crowdsourcing friendly bacteria helps superbug cause infection
Antimicrobial resistant pathogens crowdsource friendly bacteria to survive in immune cells and cause disease, a new study has revealed.

Hidden signals in RNAs regulate protein synthesis
Scientists have long known that RNA encodes instructions to make proteins. The building blocks that comprise RNA -- A, U, C, and Gs -- form a blueprint for the protein-making machinery in cells. In a new study scientists describe how the protein-making machinery identifies alternative initiation sites from which to start protein synthesis.

Getting to know the microbes that drive climate change
A new understanding of the microbes and viruses in the thawing permafrost in Sweden may help scientists better predict the pace of climate change.

Natural product that could lead to new class of commercial herbicide
A team of engineers and scientists discovered a new and potentially highly effective type of weed killer. This finding could lead to the first new class of commercial herbicides in more than 30 years, an important outcome as weeds continue to develop resistance to current herbicide regimens.

Target for novel malaria vaccine identified
Researchers have created a vaccine that protects against malaria infection in mouse models, paving the way for the development of a human vaccine that works by targeting the specific protein that parasites use to evade the immune system.
