Scientists built a camera that can track invisible particles in 3D

Unlike an ordinary camera, which mainly records the intensity of incoming light, a light field camera also captures information about the direction from which the light arrived. This allows it to recover depth and reconstruct a scene in three dimensions.

The technology relies on a micro-lens array (MLA) placed between the camera’s main lens and imaging sensor. Each microscopic lens acts like a tiny camera, recording the same scene from a slightly different angle. When the information from all of these lenses is combined, the system can reconstruct a light field, which describes the intensity, position, and direction of the incoming light.

Tesla’s selling a $225 balance bike for toddlers

Tesla’s Autopilot may fail to recognize children at times, but the company certainly recognizes their potential as future buyers. The company just unveiled the $225 Balance Bike for Kids aimed at 2–5 year olds. Like the Radio Flyer Tesla Model Y, it lacks motors or even pedals and is simply designed to be pushed along by your kids’ feet, Flintstones style.

The bike comes with a lightweight white magnesium frame, five-way adjustable seat (in black), tools for assembly, “Tesla” word mark on the side and the T logo up front. The model is for tots under 77 pounds with legs less than 13-inches long. It’s at the top of the price range for balance bikes, with only a few models priced higher (like the Woom 1 which at least has brakes) and most under $100.

Tesla has made a few products for kids before, including the $1,900 Tesla Cyberquad ATV that was recalled for violating ATV safety standards for kids. Apparently, what Tesla fans really want is a branded e-bike, and they’d willing to pay extra to get one.

New research clears the way to healing lung diseases

Pulmonary fibrosis is a deadly disease in which scar tissue grows in the lungs, making breathing more difficult. Approximately 2,170 Australians are diagnosed annually with idiopathic pulmonary fibrosis (IPF), a form of the disease with no known cause and very few treatments.

“In pulmonary fibrosis, the normal wound-healing process in the body goes wrong. Instead of repairing damaged tissue, it starts to produce scar tissue in the lungs,” said Associate Professor Gang Liu from the University of Technology Sydney (UTS) School of Life Sciences.

“People with idiopathic pulmonary fibrosis have a very short survival time, usually only two to five years from diagnosis. Only two drugs are approved to treat it, and neither can reverse the scarring and cure the disease.”
