Strange isotopes: Scientists explain a methane isotope paradox of the seafloor

(Max Planck Institute for Marine Microbiology) Deep down in the seafloor anaerobic microbes consume large amounts of methane, a potent greenhouse gas. Even though this process is a crucial element of the global carbon cycle, it is still poorly understood. Scientists from Bremen and Israel now found the solution to a long-standing enigma in this process: why methane carbon isotopes behave so differently than expected. In a joint effort with their colleagues they present the answer in the journal Science Advances.

How New Belgium’s Intentionally Bad New Beer Aims to Help Combat Global Warming – InsideHook

Not every craft beer turns out to be perfect, and in some cases, messed-up batches have turned beers like New Glarus’s Serendipity or Lagunitas’s Lagunitas Sucks from happy accidents into beloved staples. But until now, there’s never been a case…

Scientists Create World’s First Truly Biodegradable Single-use Plastic That ‘Eats Itself’ in Just 2 Weeks

Despite our efforts to sort and recycle, less than 9% of plastic gets recycled in the U.S., and most ends up in landfill or the environment. Biodegradable plastic bags and containers could help, but if they’re not properly sorted, they can contaminate otherwise recyclable #1 and #2 plastics. What’s worse, most biodegradable plastics take months […]

Scientists uncover structure of light-driven enzyme with potential biofuel applications

(DOE/SLAC National Accelerator Laboratory) Although many organisms capture and respond to sunlight, enzymes – proteins that catalyze biochemical reactions – are rarely driven by light. A new study captures the full cycle of complex structural changes in an enzyme called FAP as it transforms a fatty acid into alkanes or alkenes.

Warming homogenizes apparent temperature sensitivity of ecosystem respiration – Science Advances

INTRODUCTION Terrestrial ecosystem respiration (Re), the sum of autotrophic respiration from primary producers and heterotrophic respiration from consumers and detritivores, represents a fundamental biospheric function and plays a major role in the global carbon cycle and growth rate of atmospheric…

Living fossils: Microbe discovered in evolutionary stasis for millions of years

(Bigelow Laboratory for Ocean Sciences) Research led by Bigelow Laboratory for Ocean Sciences has revealed that a group of microbes found deep underground in three continents have been at an evolutionary standstill for millions of years. The discovery could have significant implications for biotechnology applications and scientific understanding of microbial evolution.

New study published in Science maps wildlife microbiota

(Kern Communications) Wild Biotech, a preclinical stage drug discovery & development company emerging out of stealth mode, today announces the publication of its first major paper, which appears in the journal Science. The study mapped the gut microbiota of animals in the wild on an unprecedented scale, adding millions of potentially novel microbiome-based therapeutics for human diseases to the company’s already massive database. Wild will use these findings to first tap its database for targets in inflammatory, immune and gastrointestinal diseases.

SFU lab one step closer to understanding how life started on Earth

(Simon Fraser University) How did life begin on Earth and could it exist elsewhere? Researchers at Simon Fraser University have isolated a genetic clue–an enzyme known as an RNA polymerase–that provides new insights about the origins of life. The research is published today in the journal Science.

New proteins ‘out of nothing’

(University of Münster) In a worldwide collaboration, researchers have analysed, at unprecedented breadth and depth, the evolutionary history of how a protein – which is essential for the fertility of male fruit flies and emerged from previously non-coding DNA became functional and took on a relatively stable structure.

Origin of life — Did Darwinian evolution begin before life itself?

(Ludwig-Maximilians-Universität München) A study done by Ludwig-Maximilians-Universitaet (LMU) in Munich physicists demonstrates that fundamental characteristics of polymeric molecules, such as their subunit composition, are sufficient to trigger selection processes in a plausible prebiotic setting.
