Even inactive smokers are densely colonized by microbial communities      (via sciencedaily.com)     Original source 

Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.

Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale      (via sciencedaily.com)     Original source 

Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.

Infections from these bacteria are on the rise: New blood test cuts diagnosis time from months to hours      (via sciencedaily.com)     Original source 

Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours. Rapid, accurate diagnosis has never been more important as cases of NTM infections have continued to increase annually, spreading from subtropical regions to more temperate zones in part due to global climate change.

Gut bacteria important for overcoming milk allergy      (via sciencedaily.com)     Original source 

Researchers have discovered a link between gut bacteria and the success of milk-allergy oral immunotherapy. The study found that Bifidobacterium -- a genus of beneficial bacteria in the gut -- was associated with a higher chance of successful treatment. The finding may help in the development of more effective oral immunotherapies, perhaps by combining them with probiotic supplements.

New bioengineered protein design shows promise in fighting COVID-19      (via sciencedaily.com)     Original source 

A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus responsible for COVID-19. The study focuses on the design and development of a novel protein capable of binding to the spike proteins found on the surface of the coronavirus. The goal behind this innovative approach is twofold: first, to identify and recognize the virus for diagnostic purposes, and second, to hinder its ability to infect human cells.

New simpler and cost-effective forensics test helps identify touch DNA      (via sciencedaily.com)     Original source 

Research has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and being able to identify DNA from a primary contact -- someone who may have committed the crime -- as well as secondary DNA that was inadvertently and indirectly transferred through touch.

With discovery of roundworms, Great Salt Lake's imperiled ecosystem gets more interesting      (via sciencedaily.com)     Original source 

Biologists announce the discovery of numerous species of roundworm in the highly saline waters of Great Salt Lake, the vast terminal lake in northwestern Utah that supports millions of migratory birds. Previously, brine shrimp and brine flies were the only known multicellular animals living in the water column. The scientists found nematodes, belonging to a family known for inhabiting extreme environments, in the lake's microbialites, reef-like structures covering about a fifth of the lakebed.

High resolution imagery advances the ability to monitor decadal changes in emperor penguin populations      (via sciencedaily.com)     Original source 

Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.
