Artificial Leaves Could Store Energy
An artificial silicon-based "leaf" that collects energy in much the same way as a natural one could provide a day's worth of power for homes without access to an electricity grid.
Scientists at M.I.T. look to imitate photosynthesis in their attempts to build an artificial leaf that captures and stores the Sun's energy in the form of electricity. "The leaf, a silicon-based square the size of a playing card, closely mimics the way plants use the process of photosynthesis to create energy. The device is dropped into a bucket of water, or even a muddy puddle, and placed in direct sunlight. 'Leaves are buzzing with electricity,' said Daniel Nocera, a researcher at the Massachusetts Institute of Technology who heads the research, 'they just don't have any wires in them.' Neither does the artificial leaf."
Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
The Canadian professor's old-school message is why many started listening to him.
- The simplicity of Peterson's message on suffering echoes Buddha and Rabbi Hillel.
- By bearing your suffering, you learn how to become a better person.
- Our suffering is often the result of our own actions, so learn to pinpoint the reasons behind it.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
