https://phys.org/biology-news/biotechnology/ en-us The latest science news on biotechnology Bacterial sensors usually rely on emitting light to transfer information about what they're sensing, but that method isn't practical in many settings. That's why most information transmission is done via electricity. And while electricity-emitting bacteria exist, manipulating them into useful sensors has been quite challenging. Rice University professor Caroline Ajo-Franklin's group, working in collaboration with researchers from Tufts University and Baylor College of Medicine, recently developed a flexible bioelectrical sensor system called electroactive co-culture sensing system (e-COSENS). The study is published in Nature Biotechnology. https://phys.org/news/2026-04-bacteria-chemical-electricity-options.html Biotechnology Fri, 17 Apr 2026 15:40:01 EDT news695650681 For the first time, a research team at the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) has succeeded in reducing the size of, or even completely removing, chromosomes in plants with large genomes, such as wheat. They achieved this by using the CRISPR/Cas gene-editing tool to target highly repetitive sections of DNA.

This next-generation technology can interpret experimental data, report the results and make decisions on its own. But is agentic AI smart enough to replace actual scientists? https://phys.org/news/2026-04-qa-agentic-ai-human-scientists.html Biotechnology Fri, 17 Apr 2026 12:00:04 EDT news695644443 Researchers from the University of Seville (US) and the Polytechnic University of Madrid (UPM) have demonstrated that it is possible to grow tomatoes and generate solar energy simultaneously, a key strategy for tackling global water scarcity. The study, carried out in Madrid and Seville during the spring of 2024, evaluated the use of agrovoltaic systems and regulated deficit irrigation to optimize water resources in tomato cultivation. The results show that, although using less water reduces the volume of the harvest, the overall outcome is a more efficient and sustainable process. https://phys.org/news/2026-04-agrovoltaic-generating-energy-tomato-cultivation.html Biotechnology Thu, 16 Apr 2026 20:20:02 EDT news695577422 While the Netherlands was in lockdown because of the coronavirus, Ph.D. candidate Koen Rijpkema began his research into the same virus.

Since 2014, Stony Coral Tissue Loss Disease (SCTLD) has spread rapidly across the Florida Reef Tract and Caribbean, killing vast numbers of reef-building corals and leaving behind dead skeletons where once-thriving reefs supported diverse marine life.
