A team of Japanese researchers has sent infrared photons from a microsatellite to Earth in hopes they can one day be used to quickly communicate over vast distances, according to Wired.

Why it matters: Laser communication could allow more information to be transmitted faster and microsatellites — weighing about 100 pounds and costing roughly $2 million— are cheaper to launch, potentially opening space-based communication up to companies that don't currently have the resources to operate there.

What they did: The team, led by Japan's National Institute of Information and Communications Technology physicist Masahide Sasaki, shot infrared laser beams from a satellite at a Tokyo suburb. Their vision is that one day the infrared photons could transmit information and replace today's radio waves, which can carry a limited amount of information. Messages carried by laser could potentially transfer million times more data per second, Sasaki told Wired. The challenge: Over long distances (to other planets, for example) only a few photons will arrive at the destination. The Japanese team and others — including physicists working on China's Micius satellite who conducted a similar experiment last month — are working on ways to quickly detect photons but currently Sasaki's team can "only detect about one in every hundred million photons sent from the satellite."

Go deeper: Todd Harrison, a space security expert at the Center for Strategic and International Studies, told Wired the U.S. military may "be able to use a laser-beaming sat to communicate with drones." Additionally, the small size of them could allow for more to be launched.

Joe Biden's campaign, the Democratic National Committee and joint fundraising committees raised $466 million cash on hand, the presidential candidate's team announced late Sunday.

Why it matters: President Trump's campaign raised $325 million, his campaign communications director Tim Murtaugh announced Friday. In the spring, Biden was $187 million behind Trump and the Republican National Committee.

Virtual Emmys address chaotic year for American TV and society

The Emmy Awards Sunday night addressed the major U.S. issues this year — including the protests on systemic racism and police brutality, the wildfires engulfing parts of the West Coast, the census, the pandemic, essential works and the election.

Why it matters: Award shows have always addressed wider cultural issues, but this year — amid unprecedented stress and uncertainty — that trend has accelerated.
