How researchers turn bacteria into cellulose-producing mini-factories      (via sciencedaily.com)     Original source 

Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.

Plant-inspired polymers for water purification      (via sciencedaily.com)     Original source 

Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.

The ancestor of all modern birds probably had iridescent feathers      (via sciencedaily.com)     Original source 

Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.

In clinical trial, fecal matter transplant helped half of patients with gastrointestinal cancers overcome resistance to immunotherapy treatment      (via sciencedaily.com)     Original source 

Findings from a small, proof-of-concept clinical trial have suggested that fecal microbiota transplants (FMTs) can boost the effectiveness of immunotherapy in a range of gastrointestinal cancers. In the study, six of 13 patients who had previously shown resistance to immune checkpoint inhibitors benefited from receiving FMTs from donors who had previously responded to treatment. The investigators also identified specific strains of bacteria associated with better or worse responses to FMT and immune checkpoint drugs.
