to meet ambitious goal net zero emissions by 2050The United States will have to be an innovator in renewable energy. We can multiply established technologies such as wind, Geothermalsolar energy, but it is not perfect.
For example, solar panel manufacturing comes with enormous carbon footprint and require dangerous chemicals. To search for a more sustainable source of solar energy, scientists from the Swiss Federal Institute of Technology in Lausanne (EPFL) have started on a small scale.
Well, more like a microscope: researchers have been deceived bacteria to produce solar electricity, which they hope to expand into large-scale production.
The two types of cyanobacteria they studied, synchronous And the NostockThey get their energy through photosynthesis (like plants). Adding nanomaterials such as carbon tubes can help bacteria produce significantly more electricity when illuminated by light, according to a new study published in Nature’s nanotechnology.
Now, EPFL’s lab is working on using engineered bacteria to create “living photovoltaic cells” that mimic the materials on solar panels.
live solar energy – Now, the study author Ardemis Boghossiana chemical engineer at EPFL, is looking to reduce the cost and environmental impact of placing nanotubes in bacteria.
She points out that, unlike current solar technologies, bacteria have a negative effect carbon traces: After all, they absorb carbon dioxide through photosynthesis. In the future, Boghossian hopes to program bacterial DNA to allow it to produce energy independently – without the need for nanoparticles.
You don’t need a plant to build each bacteria cell individually; Boghossian said in press release. “They automatically take in carbon dioxide to produce more of themselves. This is a materialist’s dream.”

When you peek at a cockroach, you may be tempted to crush it right away. That’s understandable, but you wouldn’t want to kill this new type of cyber bug – in fact, it could save your life one day.
An international team of engineers has created a thin and flexible structure Solar powered A device that turns cockroaches into cyborgs. It’s part of a decades-long effort by scientists to create robotic Insects that can detect victims during rescue missions (and even spy on our conversations).
The researchers created a small “backpack” that sends electrical signals to the cerci, or normal sensory structures in the back of the abdomen. This allows them to control the movements of small creatures. It’s powered by solar energy, so bugs are charged any time they roam in the sunbeam.
They hope to add different sensors to the cockroach, such as camerasthermometers, or carbon monoxide detectors, and see which works best for different processes.
