New approach for combating 'resting' bacteria      (via sciencedaily.com)     Original source 

Most disease-causing bacteria are known for their speed: In mere minutes, they can double their population, quickly making a person sick. But just as dangerous as this rapid growth can be a bacterium's resting state, which helps the pathogen evade antibiotics and contributes to severe chronic infections in the lungs and blood, within wounds, and on the surfaces of medical devices. Now, scientists have discovered how long chains of molecules called polyphosphates (polyP) are needed for bacteria to slow down movements within cells and let them enter this resting state.

Genetic underpinnings of environmental stress identified in model plant      (via sciencedaily.com)     Original source 

Researchers have identified 14 genes that thale cress -- a plant commonly used in genetic investigations since its genome is well documented -- express more when responding to five specific stressors, as well as eight genes that the plant suppresses.

Size of salty snack influences eating behavior that determines amount consumed      (via sciencedaily.com)     Original source 

The size of an individual snack piece not only influences how fast a person eats it, but also how much of it they eat, according to a new study. With nearly a quarter of daily calorie intake in the United States coming from snacks, these findings may have implications for helping people better understand how eating behavior impacts calorie and sodium intake.

Cold-affinity algae species are gradually being replaced by warm-affinity ones off the coast of Biscay      (via sciencedaily.com)     Original source 

A study has analyzed the impact of the rise in sea surface temperature on macroalgae communities over the last four decades. Points at various depths were investigated in a location off the coast of Biscay, and an increasing scarcity was observed in the number of cold-affinity structuring species, while small warm-affinity ones have proliferated. The researchers are warning that some ecological functions are in jeopardy as a result.

A microbial plastic factory for high-quality green plastic      (via sciencedaily.com)     Original source 

Engineered bacteria can produce a plastic modifier that makes renewably sourced plastic more processable, more fracture resistant and highly biodegradable even in sea water. The development provides a platform for the industrial-scale, tunable production of a material that holds great potential for turning the plastic industry green.

Do some mysterious bones belong to gigantic ichthyosaurs?      (via sciencedaily.com)     Original source 

Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.

Bacteria in cancer unmasked      (via sciencedaily.com)     Original source 

Researchers have compiled a detailed catalogue of bacteria living in cancer metastases. Having analyzed over 4000 tumors, they shed light on the diversity of these co-inhabitants and how they might interact with cancer cells and their surroundings. For example, certain bacteria were linked to a worse response to immunotherapy. This study paves the way to a better understanding of how bacteria help or hinder cancer (therapy), and how we can use this for patients' advantage.
