Millions of gamers advance biomedical research      (via sciencedaily.com)     Original source 

4.5 million gamers around the world have advanced medical science by helping to reconstruct microbial evolutionary histories using a minigame included inside the critically and commercially successful video game, Borderlands 3. Their playing has led to a significantly refined estimate of the relationships of microbes in the human gut. The results of this collaboration will both substantially advance our knowledge of the microbiome and improve on the AI programs that will be used to carry out this work in future.

Green-to-red transformation of Euglena gracilis using bonito stock and intense red light      (via sciencedaily.com)     Original source 

Euglena gracilis, often regarded as a 'superfood,' is a promising microalga with many health and nutritional benefits. In a recent study, researchers found an efficient and low-resource approach to trigger a reddening reaction in E. gracilis using red light and a bonito fish-based culture medium. This reaction is a sign of higher and diverse carotenoid content ratio, meaning the proposed method could help turn E. gracilis into an even more nutritious food source.

Even the simplest marine organisms tend to be individualistic      (via sciencedaily.com)     Original source 

Sport junkie or couch potato? Always on time or often late? The animal kingdom, too, is home to a range of personalities, each with its own lifestyle. Biologists report on a surprising discovery: even simple marine polychaete worms shape their day-to-day lives on the basis of highly individual rhythms. This diversity is of interest not just for the future of species and populations in a changing environment, but also for medicine.

Cell's 'garbage disposal' may have another role: Helping neurons near skin sense the environment      (via sciencedaily.com)     Original source 

The typical job of the proteasome, the garbage disposal of the cell, is to grind down proteins into smaller bits and recycle some of those bits and parts. That's still the case, for the most part, but researchers, studying nerve cells grown in the lab and mice, say that the proteasome's role may go well beyond that.

Bonobos are more aggressive than previously thought, study shows      (via sciencedaily.com)     Original source 

Chimpanzees and bonobos are often thought to reflect two different sides of human nature -- the conflict-ready chimpanzee versus the peaceful bonobo -- but a new study shows that, within their own communities, male bonobos are more frequently aggressive than male chimpanzees. For both species, more aggressive males had more mating opportunities.

How seaweed became multicellular      (via sciencedaily.com)     Original source 

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or 'seaweed,' to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report. Surprisingly, many of these multicellular-enabling genes had viral origins. The study, which increased the total number of sequenced macroalgal genomes from 14 to 124, is the first to investigate macroalgal evolution through the lens of genomics.
