The Bill Gates-backed venture promises to remove CO2 from the atmosphere at a rate of under $100 per tonne.
- Negative emissions technologies remove CO2 from the atmosphere and store it or convert it to fuel.
- In addition to capturing carbon, Carbon Engineering also converts stored carbon into a fuel that can be used by everyday vehicles.
- The ability to profit from carbon capture and conversion will surely help make these kinds of technologies more cost-effective.
"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."
- The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
- Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
- Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.
Humans blame cats for killing birds, but our buildings are far worse.
- Nearly a billion birds are killed every year after flying into windows.
- The American Bird Conservancy published an extensive guide to incorporating bird-friendly design into buildings.
- Over twenty cities have programs to help reduce the number of avian deaths.
A consortium of scientists and engineers have proposed that the U.S. and Mexico build a series of guarded solar, wind, natural gas and desalination facilities along the entirety of the border.
- The proposal was recently presented to several U.S. members of Congress.
- The plan still calls for border security, considering all of the facilities along the border would be guarded and connected by physical barriers.
- It's undoubtedly an expensive and complicated proposal, but the team argues that border regions are ideal spots for wind and solar energy, and that they could use the jobs and fresh water the energy park would create.
After docking at the International Space Station, the unmanned capsule executed a fiery and carefully choreographed return to Earth.
- Crew Dragon has successfully completed its six-day mission designed to test whether the capsule is fit to transport humans to the ISS.
- SpaceX and NASA collaborated on the mission, which signals an end of U.S. reliance on Russian spacecraft to transport astronauts to the space station.
- Boeing also is working with NASA to execute missions to the space station, and plans to conduct similar tests in the coming months.
