? Renewables
A report released by the National Academies of Sciences, Engineering and Medicine recommends more investment into solar geoengineering research , where sunlight is reflected back to space to artificially cool the planet.
So far, it’s a purely hypothetical idea — but scientists have proposed a number of ways it could be done.
The most common proposal suggests spraying reflective aerosols into the atmosphere, where they would beam sunlight away from the Earth. Other proposals involve making clouds brighter by injecting them with particles, or to help trap less heat beneath them.
They’re contentious ideas. Experts have many concerns about the possibility of unintended consequences, such as unwanted effects on rainfall or other global weather patterns.
California scientists are looking into covering canals with solar panels .
Their feasibility study , published in the journal Nature Sustainability, finds that if applied statewide, the panels would save 63 billion gallons of water from evaporating each year. At the same time, solar panels across California’s exposed canals would provide 13 gigawatts of renewable power annually, about half of the new capacity the state needs to meet its decarbonization goals by the year 2030.

? Cybersecurity
Google’s top security team has thwarted a nine-month hacking operation, however, it’s a counterterrorism hacking operation undertaken by a US ally , highlighting the complexity of balancing user security with national security concerns.
Instead of focusing on who was behind and targeted by a specific operation, Google decided to take broader action for everyone. The justification was that even if a Western government was the one exploiting those vulnerabilities today, it will eventually be used by others, and so the right choice is always to fix the flaw today.
Facebook says it blocked hackers in China who were trying to spy on Uyghur Muslims abroad .
Facebook said it found websites designed to look like third-party Android app stores “where they published Uyghur-themed applications, including a keyboard app, prayer app, and dictionary app.” Any apps downloaded from these sites contained malicious software to infect devices.

? Robotics
A New York lawmaker has proposed a law that will ban police use of armed robots in the future.
New York City councilmember Ben Kallos says he “watched in horror” last month when city police responded to a hostage situation in the Bronx using Boston Dynamics ’ Digidog, a remotely operated robotic dog equipped with surveillance cameras. Pictures of the Digidog went viral on Twitter , in part due to their uncanny resemblance with world-ending machines in the Netflix sci-fi series Black Mirror .
