One of Apple’s self-driving vehicles was involved in an accident during the test drive in US’ California, and sustained moderate damage in the crash, the media reported.

Apple’s autonomous car got into its very first crash one week ago in Sunnyvale, according to a report filed by Apple with the California Department of Motor Vehicles this week, The Verge reported on Friday.

However, it does not appear that Apple was at fault for the collision as the software was intact.

Apple is currently testing number of Lexus SUVs in California.

According to the accident details, the vehicle in question was in autonomous mode at the time.

The Apple car carrying special equipment and sensors was hit by a Nissan car from behind.

Both cars sustained damage but neither car’s passengers received any injuries, the report said.

Apple has a fleet of nearly 45 test self-driving vehicles in California.

The company has also partnered with Volkswagen to help create a fleet of self-driving employee shuttles for its Cupertino campus.

The self-driving cars, touted as the best bet for safe future travel, however, have been involved in some fatal accidents. On March 18, an Arizona woman was killed by an Uber self-driving car.

Five days later, the occupant of a Tesla Model X died after the vehicle hit a highway barrier in California and caught fire.

In 2016, the occupant of a Tesla running on its autopilot system in Florida was killed in a collision with a truck the Tesla car failed to spot. (IANS)

New Technology That Can Clean Water Twice As of Now

Novel technology cleans water using bacteria

Researchers, led by one of Indian-origin, have developed a new technology that can clean water twice as fast as commercially available ultrafiltration membranes, an advance that brings hope for countries like India where clean drinking water is a big issue.

According to a team from the Washington University in St. Louis, more than one in 10 people in the world lack basic drinking water access, and by 2025, half of the world’s population will be living in water-stressed areas.

The team led by Srikanth Singamaneni, Professor at the varsity, developed an ultrafiltration membrane using graphene oxide and bacterial nanocellulose that they found to be highly efficient, long-lasting and environment-friendly.

The membrane technology purifies water while preventing biofouling, or build up of bacteria and other harmful micro-organisms that reduce the flow of water.

For the study, published in the journal Environmental Science and Technology, they used bacteria to build such filtering membranes.

The Gluconacetobacter hansenii bacteria is a sugary substance that forms cellulose nanofibres when in water.

The team then incorporated graphene oxide (GO) flakes into the bacterial nanocellulose while it was growing, essentially trapping GO in the membrane to make it stable and durable.

They exposed the membrane to E. coli bacteria, then shone light on the membrane’s surface.

After being irradiated with light for just three minutes, the E. coli bacteria died. The team determined that the membrane quickly heated to above the 70 degrees Celsius required to deteriorate the cell walls of E. coli bacteria.

While the bacteria are killed, the researchers had a pristine membrane with a high quality of nanocellulose fibres that was able to filter water twice as fast as commercially available ultrafiltration membranes under a high operating pressure.

When they did the same experiment on a membrane made from bacterial nanocellulose without the reduced GO, the E. coli bacteria stayed alive.

The new technology is capable of identifying and quantifying different kinds of cyanobacteria, or blue-green algae, as a threat to shut down water systems when it suddenly proliferates. Pixabay

While the researchers acknowledge that implementing this process in conventional reverse osmosis systems is taxing, they propose a spiral-wound module system, similar to a roll of towels.

It could be equipped with LEDs or a type of nanogenerator that harnesses mechanical energy from the fluid flow to produce light and heat, which would reduce the overall cost.

If the technique were to be scaled up to a large size, it could benefit many developing countries where clean water is scarce, the researchers noted. (IANS)
