Sunflowers may be the future of "vegan meat"
A collaboration between Brazilian and German researchers has led to a sunflower-based meat substitute that’s high in protein and minerals. The new ingredient, made from refined sunflower flour, delivers excellent nutritional value and a mild flavor. Tests showed strong texture and healthy fat content, suggesting great potential for use in the growing plant-based food sector.| More info

Scientists teach bacteria the octopus’s secret to camouflage
Researchers at UC San Diego have figured out how to get bacteria to produce xanthommatin, the pigment that lets octopuses and squids camouflage. By linking the pigment’s production to bacterial survival, they created a self-sustaining system that boosts yields dramatically. This biotechnological leap could revolutionize materials science, cosmetics, and sustainable chemistry.| More info

MIT scientists discover hidden 3D genome loops that survive cell division
MIT researchers discovered that the genome’s 3D structure doesn’t vanish during cell division as previously thought. Instead, tiny loops called microcompartments remain (and even strengthen) while chromosomes condense. These loops may explain the brief surge of gene activity that occurs during mitosis. The finding redefines how scientists understand the balance between structure and function in dividing cells.| More info

Scientists just found a hidden factor behind Earth’s methane surge
Roughly two-thirds of all atmospheric methane, a potent greenhouse gas, comes from methanogens. Tracking down which methanogens in which environment produce methane with a specific isotope signature is difficult, however. UC Berkeley researchers have for the first time CRISPRed the key enzyme involved in microbial methane production to understand the unique isotopic fingerprints of different environments to better understand Earth's methane budget.| More info

New “evolution engine” creates super-proteins 100,000x faster
Researchers at Scripps have created T7-ORACLE, a powerful new tool that speeds up evolution, allowing scientists to design and improve proteins thousands of times faster than nature. Using engineered bacteria and a modified viral replication system, this method can create new protein versions in days instead of months. In tests, it quickly produced enzymes that could survive extreme doses of antibiotics, showing how it could help develop better medicines, cancer treatments, and other breakthroughs far more quickly than ever before.| More info

The EU should allow gene editing to make organic farming more sustainable, researchers say
To achieve the European Green Deal's goal of 25% organic agriculture by 2030, researchers argue that new genomic techniques (NGTs) should be allowed without pre-market authorization in organic as well as conventional food production. NGTs -- also known as gene editing --- are classified under the umbrella of GMOs, but they involve more subtle genetic tweaks.| More info

A high-fat diet sets off metabolic dysfunction in cells, leading to weight gain
Researchers find high-fat diets set off metabolic dysfunction in cells, leading to weight gain, but these effects can be reversed by treatment with an antioxidant.| More info

'Selfish' genes called introners proven to be a major source of genetic complexity
A new study proves that a type of genetic element called 'introners' are the mechanism by which many introns spread within and between species, also providing evidence of eight instances in which introners have transferred between unrelated species in a process called 'horizontal gene transfer,' the first proven examples of this phenomenon.| More info

Researchers find CRISPR is capable of even more than we thought
Newly discovered weapons of bacterial self-defense take different approaches to achieving the same goal: preventing a virus from spreading through the bacterial population.| More info

Artificial intelligence and genetics can help farmers grow corn with less fertilizer
Scientists are using artificial intelligence to determine which genes collectively govern nitrogen use efficiency in plants such as corn, with the goal of helping farmers improve their crop yields and minimize the cost of nitrogen fertilizers.| More info
