Scientists use blue-green algae as a surrogate mother for 'meat-like' proteins      (via sciencedaily.com)     Original source 

Researchers have not only succeeded in using blue-green algae as a surrogate mother for a new protein -- they have even coaxed the microalgae to produce 'meat fiber-like' protein strands. The achievement may be the key to sustainable foods that have both the 'right' texture and require minimal processing.

Cutting-edge 'protein lawnmower' created      (via sciencedaily.com)     Original source 

Scientists have designed the first synthetic protein-based motor which harnesses biological reactions to fuel and propel itself. 'Imagine if a Roomba could be powered only by the dirt it picks up,' says one of the authors of the study. The motor uses the digestive enzyme trypsin to cut the peptides and convert them into the energy it needs to propel itself.

The small intestine adapt its size according to nutrient intake      (via sciencedaily.com)     Original source 

Resizing of the intestine is a highly conserved strategy employed by a wide range of organisms to cope with fluctuation in nutrient availability. Nevertheless, very little is known about the mechanisms and signals underlying nutrient-mediated gut resizing. New research has identified one of the signaling pathways implicated in this process.

Measuring the properties of light: Scientists realize new method for determining quantum states      (via sciencedaily.com)     Original source 

Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect individual light particles -- for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing.

Biomolecular condensates -- regulatory hubs for plant iron supply      (via sciencedaily.com)     Original source 

Iron is a micronutrient for plants. Biologists now show that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light -- an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into 'biomolecular condensates' in the cell nucleus shortly after this exposure.

Metabolic diseases may be driven by gut microbiome, loss of ovarian hormones      (via sciencedaily.com)     Original source 

Mice that received fecal implants from donors that had their ovaries removed gained more fat mass and had greater expression of liver genes associated with inflammation, Type 2 diabetes, fatty liver disease and atherosclerosis. The findings may shed light on the greater incidence of metabolic dysfunction in postmenopausal women.

New system triggers cellular waste disposal      (via sciencedaily.com)     Original source 

Established treatments for cancer and other diseases often focus on inhibiting harmful enzymes to mitigate their effects. However, a more innovative approach has emerged: harnessing the cell's natural waste disposal system not just to deactivate but to entirely eradicate these proteins. Researchers have previously demonstrated the efficacy of this approach through two distinct methods. Now they unveil a third system capable of targeting and disposing of previously inaccessible proteins.
