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.

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.

Climate change will bring more turbulence to flights in the Northern Hemisphere, study finds      (via sciencedaily.com)     Original source 

A type of invisible, unpredictable air turbulence is expected to occur more frequently in the Northern Hemisphere as the climate warms. Known as clear air turbulence, the phenomenon also increased in the Northern Hemisphere between 1980 and 2021.

Artificial blood vessels could improve heart bypass outcomes      (via sciencedaily.com)     Original source 

3D-printed blood vessels, which closely mimic the properties of human veins, could transform the treatment of cardiovascular diseases. Strong, flexible, gel-like tubes -- created using a novel 3D printing technology -- could improve outcomes for heart bypass patients by replacing the human and synthetic veins currently used in surgery to re-route blood flow, experts say.

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.

A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine      (via sciencedaily.com)     Original source 

Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
