A pair of University of California - Los Angeles (UCLA) bioengineers have developed a new class of bionic 3D camera systems that can mimic flies' multiview vision and bats' natural sonar sensing, resulting in multidimensional imaging with extraordinary depth range.

The camera can decipher the size and shape of objects hidden around corners or behind other items. The technology could be incorporated into autonomous vehicles or medical imaging tools with sensing capabilities far beyond what is considered state of the art today. This research has been published in the journal Nature Communications.

In the dark, bats can visualize a vibrant picture of their surroundings by using a form of echolocation, or sonar. Their high-frequency squeaks bounce off their surroundings and are picked back up by their ears. The minuscule differences in how long it takes for the echo to reach the nocturnal animals and the intensity of the sound tell them in real time where things are, what's in the way and the proximity of potential prey.

Many insects have geometric-shaped compound eyes, in which each "eye" is composed of hundreds to tens of thousands of individual units for sight -- making it possible to see the same thing from multiple lines of sight. For example, flies' bulbous compound eyes give them a near-360-degree view even though their eyes have a fixed focus length, making it difficult for them to see anything far away, such as a flyswatter held aloft.

Inspired by these two natural phenomena found in flies and bats, the UCLA-led team set out to design a high-performance 3D camera system with advanced capabilities that leverage these advantages but also address nature's shortcomings.

"Seeing across a range of distances and around occlusions has been a major hurdle. To address that, we developed a novel computational imaging framework, which for the first time enables the acquisition of a wide and deep panoramic view with simple optics and a small array of sensors,” said study leader Liang Gao, an associate professor of bioengineering at the UCLA Samueli School of Engineering.

Called "Compact Light-field Photography," or CLIP, the framework allows the camera system to "see" with an extended depth range and around objects. In experiments, the researchers demonstrated that their system can "see" hidden objects that are not spotted by conventional 3D cameras.

Hundreds of firefighters were battling wildfires in the forests of northern Japan on Saturday, as authorities urged more than 3,200 people to evacuate from their homes, government officials said.

As of Saturday morning, blazes in the mountainous areas of Iwate region had burned about 700 hectares (1,730 acres) since breaking out three days ago, local government officials said in a statement.

A large column of smoke, which could be smelled 30 kilometers (20 miles) away, was seen rising up the valley near the town of Otsuchi as two helicopters dropped water on the burning forest.

In Otsuchi, fire engines were spraying the forest near homes close to the fire.

About a dozen helicopters and more than 1,300 firefighters as well as Japan Self-Defense Forces troops would be mobilized on Saturday to battle the fires, the statement said.

At least eight buildings had been burnt but all the residents had evacuated, it said.

"We're making efforts to extinguish (the fires) ... and will update the information" later in the day, an Iwate official told AFP.

"Ultimately, I do hope it'll rain," a man in Otsuchi told public broadcaster NHK.

Increasingly dry winters have raised the risk of wildfires. A blaze that broke out in the Iwate city of Ofunato early last year was Japan's worst in more than half a century.

Scientists have long warned that climate change caused by mankind's burning of fossil fuels will make periods of drought more intense and longer-lasting, creating the ideal conditions for wildfires.

Officials and visitors from Australia, New Zealand and Turkey gathered in northwest Türkiye on Saturday to commemorate the 111th anniversary of the Battle of Gallipoli.

The solemn ceremony began at 5:30 a.m. local time near a beach where the Australian and New Zealand Army Corps, or Anzacs, first landed at Gallipoli at dawn on April 25, 1915.

The hour-long event included mournful hymns, prayers and the laying of wreaths by the participants, which included representatives from many countries around the world.

The Gallipoli campaign, part of a British-led effort to defeat the Ottoman Empire, ultimately failed, resulting in tens of thousands of deaths on both sides during the eight-month conflict. It aimed to secure a naval route from the Mediterranean Sea to Istanbul through the Dardanelles, and knock the Ottomans out of the war.

The battle helped forge Australia and New Zealand’s national identities, as well as friendship with their former adversary, Türkiye.

“From great suffering, understanding can grow. From former enemies, friendships can blossom. The relationship between Türkiye, Australia and New Zealand is built on remembrance, respect and recognition of our shared humanity,” said Governor-General of New Zealand Dame Cindy Kiro during the opening address.

Turkish Col. Fatih Cansiz read from the tribute Türkiye’s founder Mustafa Kemal Ataturk made in 1934 for the fallen: “Those heroes that shed their blood and lost their lives ... you are now lying in the soil of a friendly country. Therefore, rest in peace. There is no difference between the Johnnies and the Mehmets to us where they lie side by side in this country of ours.”

Ataturk first rose to prominence as commander of the Turkish forces at Gallipoli, then went on to lead Türkiye’s War of Independence and ultimately found the Turkish Republic.

Two giant pandas from China are headed to Atlanta on a new 10-year conservation deal.

Pandas Ping Ping, a male, and Fu Shuang, a female, will live at Zoo Atlanta, China Wildlife Conservation Association said in a statement Friday.

The organization signed the research agreement with the United States zoo last year, it said, noting the deal continues "the 'panda bond' shared by the people of both nations for more than 20 years".

The panda pair come from the Chengdu Research Base of Giant Panda Breeding in southwestern Sichuan province, according to the statement.

"Zoo Atlanta is delighted and honored to yet again be trusted as stewards of this treasured species," the zoo's president Raymond B. King said in a statement.

"We can't wait to meet Ping Ping and Fu Shuang."

The zoo welcomed its first giant pandas Yang Yang and Lun Lun when they arrived in 1999.

That pair produced seven cubs over a 25-year agreement before returning to China with their two youngest in 2024, when that deal expired.

The US side has prepared for Ping Ping and Fu Shuang's arrival by renovating their habitat to make it "more comfortable and more safe", the Chinese association said.

The panda news comes as US President Donald Trump is expected to meet his Chinese counterpart Xi Jinping in Beijing next month.

A Chinese foreign ministry spokesman said on Friday the new deal "will contribute to the well-being of giant pandas... and the friendship between the people of China and the US".
