An unconventional photography exhibition in London has turned toxic pollution into art to raise awareness about the British capital's persistent air-quality problems.

Visual artists and scientists have teamed up for the exhibition, entitled What On Earth, which explores the climate crisis through 26 artworks, running until July 24.

Exhibits include ethereal images on delicate dark blue paper with splashes of white that evoke pristine oceans but actually show the contamination of London's air.

They were produced using air samples provided by scientists at Imperial College London.

The samples were then captured and printed using cyanotype, a traditional method of producing images from light that enables sunlight to reveal toxic particles.

The Crown Estate, which manages property owned by Queen Elizabeth II, gave The Koppel Project, the arts charity behind the show, a disused retail unit rent-free for a year in sought-after central London.

The deal was in exchange for establishing an artistic community and getting a discussion under way, said curator Ellen Taylor.

"The goal was to address social and political issues we see in the news to create a conversation," she said.

"I'm hoping this show can demonstrate how nature can be the subject of photography, using air pollution and sound to document how our environment is changing."

Pollution levels plummeted across the world last year as people stayed at home during coronavirus lockdowns but have picked up as restrictions ease and more people avoid public transport.

Air pollution can create and exacerbate cardiovascular diseases and asthma and has been linked with cognitive diseases like dementia.

The World Health Organization (WHO) estimates it is responsible for seven million premature deaths annually worldwide.

A June report found that more than 25 percent of UK schools were located in areas above the WHO's recommended air pollution levels.

- 'Pea soup' -
One of the showcased artists Alice Cazenave used a glass plate to collect pollution in central London for weeks.

The city has a long history of poor air quality, with its thick "pea soup" smog leading to major clean air legislation in the 1950s.

It introduced a congestion charge in 2003, billing motorists entering the city centre £15 ($21, 18 euros) every day.

The owners of vehicles exceeding emissions thresholds will pay additional fees of up to £100 in an expanded low-emission zone from October, as Sadiq Khan seeks to become the city's "greenest mayor".

Air pollution caused around 1,000 annual hospital admissions for asthma and serious lung conditions in London between 2014 and 2016, according to a 2019 report.

In December, a coroner ruled that air pollution made a "material contribution" to the death of a nine-year-old London girl in 2013 -- the first time in Britain that air pollution was officially listed as a cause of death.

It is against this backdrop that the exhibition wants to put the issue at the forefront of people's minds and encourage action.

"The processes and subject matter is a great way to show the ever-changing environment we see today," added Taylor.

An ancient jawbone discovered in Taiwan belonged to an enigmatic group of early human ancestors called Denisovans, scientists reported Thursday.
Relatively little is known about Denisovans, an extinct group of human cousins that interacted with Neanderthals and our own species, Homo sapiens.
“Denisovan fossils are very scarce,” with only a few confirmed finds in East Asia, said study co-author Takumi Tsutaya at the Graduate University for Advanced Studies in Japan.
So far, the only known Denisovan fossils include partial jawbones, a few teeth and part of a finger bone found in caves in Siberia and Tibet. Some scientists believe fossils found in a cave in Laos may also belong to Denisovans, The Associated Press reported.
The probable identification of the jawbone from Taiwan as Denisovan expands the region where scientists know these ancient people once lived, said Tsutaya.
The partial jawbone was first recovered when a fishing operation dredged the seafloor in the Penghu Channel near the Taiwan Strait. After it was sold to an antique shop, a collector spotted it and purchased it in 2008, then later donated it to Taiwan’s National Museum of Natural Science.
Based on the composition of marine invertebrates found attached to it, the fossil was dated to the Pleistocene era. But exactly which species of early human ancestor it belonged to remained a mystery.
The condition of the fossil made it impossible to study ancient DNA. But recently, scientists in Taiwan, Japan and Denmark were able to extract some protein sequences from the incomplete jawbone.
An analysis showed some protein sequences resembled those contained in the genome of a Denisovan fossil recovered in Siberia. The findings were published in the journal Science.
While the new research is promising, Rick Potts, director of the Smithsonian Institution’s Human Origins Project, said he would like to see further data before confirming the Taiwan fossil as Denisovan.
Potts, who was not involved in the new research, praised the study for “a fantastic job of recovering some proteins.” But he added, such a small sliver of material may not give a full picture.
At one time, at least three human ancestor groups — Denisovans, Neanderthals and Homo sapiens — coexisted in Eurasia and sometimes interbred, researchers say.
“We can identity Neanderthal elements and Denisovan elements" in the DNA of some people alive today, said Tsutaya.
