Luminar, a secretive five-year-old Silicon Valley startup, has been trying to improve one of the components central to most self-driving cars. The company has its own take on LiDAR, the laser-based sensor that helps autonomous vehicles "see" the world around them. And according to its 22-year-old CEO, Luminar's technology will pave the way for autonomous cars that are better, cheaper and safe.

Why this matters: Luminar says it's designed-from-scratch LiDAR devices can be cheaper and more accurate.

Core technology: Once obscure LiDAR sensors have become all the rage thanks to the recent self-driving car boom. LiDAR sensors project eye-safe laser beams around them, and measure how fast the light is reflect back to map out the objects and environment around them. Everyone from Alphabet and Uber to traditional car makers like General Motors rely on LiDAR as a key part of their self-driving car efforts. LiDAR sensors are also at the center of an on-going trade secret theft dispute between Waymo (Alphabet's self-driving car unit) and Uber.

Better and cheaper: According to Luminar founder and CEO Austin Russell the company has designed its LiDAR devices from scratch, including the chips, yielding a design that he says offers more accurate maps than the competition. Namely, Luminar's LiDAR uses lasers at a 1550 nanometer wavelength, not the commonly used 905 nanometer wavelength. It's also ditched the conventional silicon and built its chips out of indium gallium arsenide, which Russell says contributes to increased performance. Eventually, Russell believes Luminar's devices will also be significantly cheaper than anything currently available on the market costing tens of thousands of dollars, though he declined to say how much a unit currently costs to manufacture or the company's near-term cost targets.

The company: Luminar already has 150 employees, and recently opened a facility in Orlando, a hotbed of optics engineering talent. It has acquired two companies, including Open Photonics, whose co-founder, Jason Eichenholz, became Luminar's CTO. It's gearing up to manufacture its first 10,000-unit run of its latest device.

Funding: Luminar raised $36 million in seed funding since its founding in 2012 from Canvas Ventures, GVA Capital, and the Peter Thiel-backed 1517 Fund, among others.

Newly released transcripts of bodycam footage from the Minneapolis Police Department show that George Floyd told officers he could not breathe more than 20 times in the moments leading up to his death.

Why it matters: Floyd's killing sparked a national wave of Black Lives Matter protests and an ongoing reckoning over systemic racism in the United States. The transcripts "offer one the most thorough and dramatic accounts" before Floyd's death, The New York Times writes.

Fighting the coronavirus infodemic

An "infodemic" of misinformation and disinformation has helped cripple the response to the novel coronavirus.

Why it matters: High-powered social media accelerates the spread of lies and political polarization that motivates people to believe them. Unless the public health sphere can effectively counter misinformation, not even an effective vaccine may be enough to end the pandemic.
