Saudi KAUST Researchers Develop Lithium-Metal Battery

Scientists at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST), in collaboration with their counterparts at King Abdulaziz City for Science and Technology (KACST), have made a breakthrough that could increase the power and lower the cost of lithium-metal batteries by incorporating nylon into the design.

In a statement on Sunday, KAUST said the study highlights the advantages of lithium metal batteries, known for their high energy density and lightweight properties, over conventional lithium-ion batteries.

While lithium-ion batteries remain the industry standard, lithium-metal batteries offer superior performance, making them ideal for applications in robotics, transportation, and consumer electronics. However, current production methods rely on hazardous and corrosive chemicals that compromise efficiency and safety.

Head of the KAUST Center of Excellence for Renewable Energy and Storage Technologies Professor Husam Alshareef said: “My research team is dedicated to building renewable energy and storage solutions such as higher energy density and safer batteries to accelerate decarbonization adoption in the Kingdom. This was a discovery that promises cheaper and safer additives and demonstrates the benefits of basic scientific research.”

Strange Foam and Dead Fish Wash Ashore at 2 Australian Beaches as Surfers Fall Sick

An Australian state closed two beaches after dead fish and an unusual off-white foam washed ashore while surfers reported feeling unwell, officials said on Tuesday.

A microalgal bloom created by unusual weather conditions was suspected to have sickened humans and marine life as well as creating the foam that has covered hundreds of meters (yards) of coastline, South Australian Environment Protection Authority principal scientific officer Sam Gaylard said.

“It is very concerning,” Gaylard told Australian Broadcasting Corp.

“It is unusual at this scale. At this time of year, when the weather conditions allow, we do occasionally get isolated blooms, but something of this scale is definitely a little bit unusual,” Gaylard added.

Waitpinga Beach and neighboring Parsons Beach, both south of the South Australia state capital Adelaide, have been closed to the public since Monday in response to a “fish mortality event in the area,” the Department for Environment and Water said in a statement.

“The beaches will be re-opened as soon as possible,” the department said.

Dozens of dead fish have reportedly been washed ashore.

Surfers have been complaining since the weekend of getting sore eyes, sore throats and coughing after contact with the water, said local Anthony Rowland, who surfed at Waitpinga on Saturday.

“While we were out there, we started coughing,” Rowland said, referring to his surfing comrades. He said he was overwhelmed by the response from other surfers after posting his experience online.

“Lots of people reached out – so many people have said they’re had exactly the same symptoms,” Rowland said.

Marine scientists took water samples from the foam, which is a byproduct of the toxic organisms' decay, on Monday, but it could take until the end of the week to identify the organism, Gaylard said.

A bloom of microalgae – microscopic, single-celled organisms – could have been caused by a recent extended period of hot and dry weather with little wind and low tides, Gaylard said.

A swell has picked up in the area since Sunday, and the turbulence could break up the algae while generating more foam, he said.

“At the moment, we’re not sure how long this will last,” Gaylard said.
