A Ukrainian farmer has come up with a novel way to remove mines left in his fields after Russia's invasion -- he's kitted out his tractor with protective panels stripped from Russian tanks and operates it by remote control.

After Russian forces were driven back from parts of eastern Ukraine by a Ukrainian counteroffensive last year, mines remained in many fields, making it perilous for farmers to sow grain for the next harvest.

Fields around the village of Hrakove was no exception. Oleksandr Kryvtsov, a general manager at his agricultural company, decided he couldn't wait for help from overworked official deminers to clear his field.

Instead, he designed a remote-controlled tractor that could withstand blasts. Using armor from damaged Russian military vehicles to protect the body of his tractor, he bought a system that would enable one of his team to operate the tractor remotely from a digger's bucket suspended in the air nearby.

"We started doing this just because the crop-sowing time has come and we can’t do anything because the rescue services are very busy," Kryvtsov told Reuters.

"We ran over an anti-tank mine. The protection got blown out (but) the tractor is safe," he said." Everyone's alive and safe. The equipment was restored and repaired."

Prime Minister Denys Shmyhal said last week about 30% of Ukrainian territory had been mined by Russians and that the government was focused on de-mining agricultural land as quickly as possible.

"We have no time to demine the fields. The amount of work is enormous," said Serhii Dudak, head of a demining unit overseeing the tractor's work. "It would take years to demine this particular field by hand and to guarantee that there are no mines here."

An "amphibious mouse" with partially webbed feet that eats aquatic insects was among 27 new species discovered during a 2022 expedition to Peru's Amazon, according to Conservation International.

Scientists also discovered a spiny mouse, a squirrel, eight types of fish, three amphibians and 10 types of butterflies, Trond Larsen, head of Conservation International's Rapid Assessment Program, told Reuters this week.

He added that another 48 species found by investigators were potentially new, but needed further study.

The new species were found in Alto Mayo, a protected area with several ecosystems, Indigenous territories and villages.

"Discovering so many new species of mammals and vertebrates is really incredible, especially in such a human-influenced landscape as Alto Mayo," Larsen said.

The expedition between June and July 2022 was made up of 13 scientists plus local technicians and members of Indigenous groups.

"It was really fantastic to work so closely with the Awajun people. They have extensive traditional knowledge about the forests, animals and plants they live side-by-side with," Larsen said.

Among the new species, Larsen highlighted the spiny mouse that has stiff fur, the amphibious mouse, and a dwarf squirrel that measures 14 cm (5.5 in).

"(The squirrel) fits so easily in the palm of your hand. Adorable and beautiful chestnut-brown color, very fast," Larsen said. "It jumps quickly and hides in the trees."

Another favorite discovery was the blob-headed fish, a type of armored catfish, he said.

A total of 2,046 species were recorded during the 38-day expedition using camera traps, bioacoustic sensors and DNA sampling. Among them, 49 were classified as threatened, including the yellow-tailed woolly monkey and the tree monkey.

Larsen said the discoveries reinforced the need to protect the area.

"Unless steps are taken now to safeguard these sites and help restore parts of the landscape ... there's a strong chance they won't persist in the long term," Larsen said.
