SYDNEY, Nov 21 (Reuters) — Some residents of a remote Papua New Guinea island were preparing on Tuesday to evacuate from the vicinity of an erupting volcano that shot a cloud of ash into the sky forcing the cancellation of some flights.

Teams had been sent to the Mount Ulawun area on New Britain island to coordinate an evacuation after it began erupting on Monday, state broadcaster NBC PNG reported senior disaster management official Clement Bailey as saying.

Flights from the island’s Hoskins airport had been cancelled, the broadcaster said, adding that the volcano was still erupting.

Ken, a 36-year-old Uber and Lyft driver in Houston, drives about four to five hours per day — in addition to his full-time analyst job — to supplement his income. Last year, he earned a combined $25,000 driving for Uber and Lyft from about 2,000 trips, according to screenshots of earnings documents viewed by Business Insider.

While he accepts most rides, he said he prioritizes trips that pay at least $0.80 to $1.00 per mile, excluding vehicle expenses — a ride’s base pay and distance are displayed on the app. He also tries to avoid trips that take him too far out of Houston because he worries he won’t be able to find trips for the ride back. He calls these “empty miles.”

“I have seen a 50-mile trip that only $20 was offered,” Ken previously told Business Insider. “I wouldn’t be doing that.” He asked that his last name not be included for fear of professional repercussions.

The company has already pledged to phase out all internal-combustion models by 2033.

Announced on the DARPA website on the 1st of November 2023, the chosen few will design and build a prototype vertical takeoff and landing aircraft (VTOL) “to demonstrate the key technologies and integrated concepts that enable a transformational combination of aircraft speed and runway independence.”

Lithium metal, chosen for battery anodes due to its superior energy density compared to other materials, is a smart choice. Yet, challenges arise at the interface between the electrode and the electrolyte, presenting opportunities for enhancement to achieve safer and more efficient performance in future applications.

Researchers from Tsinghua University are keen on replacing the graphite anode with a lithium metal anode to construct a battery system with higher energy density. However, the Li metal anode is unstable and readily reacts with electrolytes to form a solid-electrolyte interphase (SEI). Unfortunately, the natural SEI is brittle and fragile, resulting in poor lifespan and performance.

Here, the researchers have looked into a substitute for natural SEI, which could effectively mitigate the side reactions within the battery system. The answer is ASEI: artificial solid electrolyte interphase. ASEI corrects some of the issues plaguing the bare lithium metal anode to make a safer, more reliable, and even more powerful source of power that can be used with more confidence in electric vehicles and other similar applications.

STOCKHOLM (AP) — Many cities around the world see clean and efficient public transport as a crucial way to lower their carbon emissions. For cities with waterways, a high-tech ferry in Sweden could soon set a new standard.

Speeding through Stockholm’s archipelago, electric boat maker Candela’s new P-12 vessel barely makes a sound as it glides over a meter (3 feet) above the water. Its developers hope the ferry, which was unveiled this week, will yield a new era of waterborne public transport.

“This is a real leap forward,” said Erik Eklund, who is in charge of the commercial vessel division at Candela. “The energy savings we get by going airborne on the foils give us the speed and range we need to make this work on batteries.”

A recent video that went viral on social media showed off the entirety of the truck’s interior for the first time, suggesting the cabin of the Cybertruck will be more cramped than one might expect from a full-sized pickup.

Oddly, it’s now starting to sound like the same could go for the truck’s bed. One image circulating online shows that not even a single mountain bike can fully fit inside the bed.

And a separate image uploaded to the Cybertruck subreddit shows most of a Christmas tree awkwardly protruding from the back of the truck, suggesting it’s not exactly going to compete with other pickup trucks when it comes to utility alone.

Two symmetrical steel arches define this bridge by Zaha Hadid Architects, which stretches 295 metres across a tributary of the Tuojiang River in Chengdu, China.

Named Jiangxi River Bridge, the structure is used by cars, cyclists and pedestrians and is intended to become a landmark for the city in Sichuan province.

Zaha Hadid Architects designed the bridge to tie in with the city’s existing road system and Airport New Town, a new development surrounding Chengdu Tianfu International Airport.

Scientists have built noise-canceling headphones that filter out specific types of sound in real-time — such as birds chirping or car horns blaring — thanks to a deep learning artificial intelligence (AI) algorithm.

The system, which researchers at the University of Washington dub “semantic hearing,” streams all sounds captured by headphones to a smartphone, which cancels everything before letting wearers pick the specific types of audio they’d like to hear. They described the protoype in a paper published Oct. 29 in the journa IACM Digital Library.
