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.

A European spacecraft has begun close inspections of an asteroid rammed by NASA four years ago in a planetary defense test.

The European Space Agency announced Wednesday that the Hera spacecraft is now studying Didymos and its moonlet Dimorphos from just 15 miles to 18 miles (25 kilometers to 30 kilometers) away, The AP news reported.

NASA’s Dart spacecraft deliberately slammed into little Dimorphos in 2022 to see whether such a defensive move might help save Earth from a killer space rock one day.

The impact shortened the moonlet’s orbit around Didymos. More importantly, it nudged the moonlet into a slightly different path around the sun.

Next month, the small car-sized Hera, launched in 2024, will venture even closer — just 12 miles (20 kilometers) away.

ESA officials consider this a “crash site investigation” worthy of its finest robotic detective. Hera is carrying 25 science instruments as well as a pair of shoebox-sized Cubesats to survey Dimorphos even more closely and attempt to land on it.

The Dart spacecraft — short for Double Asteroid Redirection Test — sent rubble and even boulders flying off Dimorphos, providing an extra kick to the impact’s momentum. The debris trail extended thousands of miles (more than 10,000 kilometers) into space for months.

Some of that debris could still be in the vicinity, according to scientists.

Dimorphos is an estimated 500 feet (151 meters) in diameter. Didymos is roughly 2,560 feet (780 meters) in diameter.

The European Space Agency has released its first big collection of data from the orbiting Euclid telescope's mission to map the universe's large-scale structure, including observations of more than 900 million galaxies, as scientists investigate the puzzling cosmic components dark matter and dark energy.

The data unveiled on Thursday covered a survey of the sky equal to about 9,500 times the size of the moon as viewed from Earth. The mission's goal is to complete the largest-ever three-dimensional atlas of the cosmos, spanning more than a third of the sky, in 2031.

Thursday's release encompassed around 13 months of Euclid observations, totaling an enormous 1.7 petabytes — 1.7 million gigabytes — of data, Reuters reported.

"It marks a major milestone for ESA's Euclid mission and for everyone involved," said astrophysicist Valeria Pettorino, ESA's Euclid project scientist.

Euclid, launched from Florida in 2023, is gathering data on how the universe has expanded and how its structure has formed over time while amassing information about the nature of dark energy and dark matter and the role of gravity on large scales.

"Euclid will not just take images of galaxies in the sky, in two dimensions, but will also measure their distance, the third dimension. This will tell us where galaxies are in space and time, across 10 billion years, and in all directions beyond our galactic plane," Pettorino said.

"Galaxies cluster along filaments, surrounded by empty space, and form a network that we call the cosmic web. Euclid will reconstruct the cosmic web and how it has grown over time. This is important because the exact configuration of the cosmic web, how many clusters or voids are there, how fast it changed, depend on the properties of dark energy and dark matter," Pettorino said.

The universe's contents include ordinary matter as well as dark matter and dark energy.

Ordinary matter — stars, planets, gas, dust and all the familiar stuff on Earth — represents about 5% of the contents. Dark matter, known from the gravitational effects it exerts on galactic scales, is invisible material that may make up about 27% of the cosmos. Dark energy, thought to be responsible for the accelerated expansion of the universe, may account for 68%.

Dark matter and dark energy do not emit or absorb light and cannot be directly observed.

Previous Euclid data releases covered only a few days of observations. The newly released dataset includes more than a year of data and still spans only 14% of the total sky area Euclid is due to survey in visible and near-infrared light over six years. This data release will be completed next year with the first results on dark energy and dark matter.

GRAVITATIONAL LENSING

Light traveling toward Earth from faraway galaxies can be bent and distorted by normal matter and dark matter in the foreground, an effect called gravitational lensing. Thus, the nearer galaxy's gravity warps the light coming from the one behind.

Gravitational lensing is one of the tools being used to study dark matter's distribution. The new Euclid data includes about 15,000 strong gravitational lens candidates, exceeding the total number discovered in the previous half century.

"Gravitational lenses are nature's own weighing scales," said Natalie Lines, a doctoral student in astrophysics at the University of Portsmouth in England and a member of the Euclid Consortium of scientists.

"How strongly the light is bent tells us how much matter a galaxy contains, including invisible components like dark matter. With thousands of lenses, we can study how dark matter is spread through galaxies and understand how galaxies form and evolve over cosmic time," Lines said.

Lines noted the sharpness of the Euclid images over a huge area of the cosmos.

"Telescopes on Earth can cover large areas of the night sky, but their view is blurred by the atmosphere. The Hubble and James Webb space telescopes take beautifully sharp images, but only of tiny patches of sky. Euclid does both at once, and that is crucial for finding things that are small and rare, like strong gravitational lenses," Lines said.

Looking across vast distances means peering into the past because of the time needed for light from distant objects to reach us. The most distant objects Euclid has viewed are quasars, the brilliant cores of galaxies powered by supermassive black holes. The telescope has pinpointed 60 million of them.

"Euclid has found some dating back to when the universe was just 5% of its current age, so their light set off around 13 billion years ago," Lines said.

The Sustainable Agricultural Rural Development Program (Saudi Reef) reported that Saudi coffee production rose from 800 tons annually in 2020 to approximately 7,400 tons in 2026, an increase of more than 825%, supporting Saudi Vision 2030 objectives.

Saudi Reef spokesperson Majed Al-Buraikan said the number of beneficiaries in the coffee sector exceeded 6,200 in 2026, up 207% from 2021, while total support surpassed SAR 185 million, SPA reported.

The funding supports small-scale producers, agricultural investment, and coffee value chains.

Al-Buraikan said approximately 4.4 million coffee seedlings are expected to raise production to more than 20,000 tons at full capacity.

The program also provides specialized training in organic farming, pest control, modern irrigation, and coffee cultivation.

Development efforts included producing 1,000 improved cuttings to enhance varieties and productivity, agricultural projects involving 8,000 coffee seedlings, and cultivation trials at 12 sites to expand cultivation and improve yields, quality, and sustainability.

The program’s 2026 targets included increasing annual production to 7,000 tons and raising self-sufficiency from 0.5% to 4.4%. Actual production exceeded the target, reaching 7,400 tons.
