While recycling is a mathematically obvious response to the finite, non-renewable nature of many resources, the economic math is often challenging. For many materials, it can be hard to compete with virgin materials on a cost basis. Fast-moving technologies like electric vehicles throw in an added complication: By the time a car is scrapped, the industry may have moved on to a different battery chemistry. That reduces the value of recycling the car’s battery back into the production chain. Still, a study led by Xin Xiong at Nanjing University finds that in China, recycling could become the dominant source of…

Surfers Against Sewage (SAS) has developed their own app, external developed an app to provide alerts when bathing water quality could be affected by pollution, including sewage spills.It says the information comes from various sources including voluntarily data from water companies in England and Wales, from sensors that monitor when a Combined Sewer Overflow operates. The alert stays live for 48 hours post-discharge.It says UK water companies keep pollution alerts active for varying periods so “for the safety of water users, SAS follows the precautionary approach to keep the current alerting system in place at 48 hours”.The app also includes…

After Victoria withdrew in 2023, Glasgow answered the SOS call – and organisers say the past 11 days in the Scottish city have “exceeded all expectations”.Yes, there have been grumbles – including from those who have seen parking spaces outside their houses taken – and taxi drivers and shop owners the Games have passed by.On the ground, though, this felt like a meaningful event.Ticket sales of 434,000 were well down from 1.5 million for Birmingham 2022, but they were always going to be given the smaller venues for this scaled-back edition. It has been rare to enter a venue and…

If anyone happened to pass by Central Park’s Rumsey Playfield on Saturday night, it was clear there wasn’t just any event going on. Thousands of fans flooded the area, brimming with excitement as they counted down to see Trueno, Milo J, and J Noa take on Capital One City Parks Foundation SummerStage. This show had been one of the most anticipated of the summer series: Argentine rappers Trueno is one of the most exciting rising stars in Latin America, selling out massive stadiums across the globe. Milo J, one of Trueno’s peers and collaborators also from Argentina, has won over…

The leader of Restore Britain, Rupert Lowe, has extended an olive branch to Nigel Farage, saying the two should put “personalities and our past disagreements aside for the good of the country”.Lowe told the Reform UK leader that if he was “prepared to work together around serious policies, serious reform and serious government, then so are we”.In a video posted on X, Lowe said: “I truly believe there could be sufficient common ground for our two movements to cooperate collectively, destroy the looming leftwing alliance that will finish off what hope remains for this country.“In my view, failing to even…

The Executive Chairman of United Nigeria Airlines (UNA), Prof. Obiora Okonkwo, has been conferred with a gold medal award by the Institute of Nigerian Aeronautical Engineers (INAE), in recognition of the airline’s safety culture, capacity building and rapid growth despite a turbulent economic climate. The award, presented by the national president of INAE, Dr. Ebitei Charles, at the International Conference Fellowship Conferment which held in Lagos on Wednesday, is reserved for individuals whose work has significantly advanced the field of aeronautical engineering. The Institute said Okonkwo was honoured for steering UNA’s rapid expansion in the five years since its inception,…

The solution Tang’s team arrived at starts with the way infrared light is registered in the first place. Selective quantum dots Bulk semiconductors routinely used in IR detectors have continuous energy bands, which means they absorb a broad, undifferentiated swath of the infrared spectrum. This doesn’t preserve much information about which specific wavelength arrived. The mercury telluride colloidal quantum dots the Chinese team picked for their device behave differently. Due to their tiny size, roughly 4 nanometers across, quantum confinement breaks their energy levels into discrete steps rather than a continuous chunk. Photons of different infrared wavelengths and intensities excite…

Jon Beresford, one of BAR’s founders, said finding a peregrine on the ground was unusual.”Unlike the vast majority of birds, when they fledge they don’t land on the ground, they have short flights from the nest and they go back to the nest.”So somehow she was found grounded and injured. “So I suspect during her first trips from the nest flying, she’s come a cropper, she’s hit something,” he said.It was found the bird was the offspring of a male peregrine successfully treated by BAR last year.But the shelter did not have the facilities for a young bird to continue…
