China's robotics industry pivots from 'body' to 'brain' as commercial race heats up

Dobot Atom AI robot
Dobot claims its self-developed vision-language-action model lets humanoid robots react to the real world rather than just perform preprogrammed tasks

Chinese humanoid robotics companies are doubling down on developing intelligent models, as investors eye advances in robot "brains" as the next step towards real-world commercial use.

Shenzhen-based Dobot said on Wednesday that it delivered its third batch of mass produced, full-size humanoid Atom robots, marking a shift from laboratory concept to an industrialised product.

Dobot, listed in Hong Kong, said its self-developed Dobot-VLA, a vision-language-action model, enabled Atom to react to uncertainties in the real world rather than just perform preprogrammed tasks.

Star-killing black hole is one of the most energetic objects in the universe โ€” and it's getting brighter

The powerful 'Jetty McJetface' feature was discovered in one such system.
Scientists say a jet from a previously studied supermassive black hole has grown brighter, becoming one of the most energetic events in the universe.

The jet โ€” nicknamed "Jetty McJetface" โ€” is emanating from a black hole that was previously studied in 2022, after it picked up a star and began shredding it to pieces, releasing the jet in the process. Now, some four years later, that bout of "cosmic indigestion" is still going strong, researchers said.

"This is really unusual," Yvette Cendes, an astrophysicist at the University of Oregon who led the study published Feb. 5 in the Astrophysical Journal, said in a statement. "I'd be hard-pressed to think of anything rising like this over such a long period of time."

Many such star-shredding events have been spotted before, when a star gets too close to the gravitational field to a black hole and is violently torn apart in a process called "spaghettification." But such energy from spaghettification has never been seen before, Cendes said.

A new study has revealed that the iconic Black Beauty meteorite contains much more hidden water than previously suspected. The rock, which fell to Earth from Mars, could reveal clues about the Red Planet's watery past.

Many tiny specks of ancient water are locked within one of the oldest and most famous Martian meteorites ever to fall to Earth, a new study finds. The surprising discovery, achieved using a new form of "neutron scanning," reveals more clues about the Red Planet's watery past, which may have set the stage for extraterrestrial life to flourish.

Meteorite NWA 7034, more commonly known as Black Beauty, is a roughly 11-ounce (320 grams) chunk of Mars that was ejected when another space rock slammed into the Red Planet. It was discovered in 2011 by nomads in the Moroccan region of the Sahara Desert, although it is unclear when it fell to Earth. The meteorite has since become famous for its dark hue, which has been further accentuated by heavy polishing on one of its faces.

Comet 2

A new comet was just discovered. Will it be visible in broad daylight?

A newly discovered comet has astronomers excited, with the potential to be a spectacular sight in early April.

C/2026 A1 (MAPS) was spotted by a team of four amateur astronomers with a remotely operated telescope in the Atacama desert on January 13.

It quickly became apparent the newly discovered object was a member of a group called the Kreutz sungrazing comets. These include many of the brightest and most spectacular comets ever seen.

Comet MAPS is moving on an extreme, highly elongated orbit around the Sun, and is diving towards a fiery date with our star. In early April the comet will pass within just 120,000km of the Sun's surface.

If the comet survives, it could become a spectacular sight in the evening sky in early April. It may even become visible in broad daylight as it swings closest to the Sun - unless it falls apart before then.

So what makes these sungrazers so exciting, and what can we expect?

Bezos' Blue Origin Pauses Space Tourism To Focus On The Moon

Blue Origin New Shepard lift off
Blue Origin decided to shift its focus from the edge of space to the Moon.

The company announced on Jan. 30 that it was pausing all of its suborbital commercial flights on its reusable New Shepard rocket for no less than two years in order to focus more resources on delivering a crewed lunar lander to NASA in time to meet Congress's set deadline to establish a permanent human presence on or around the moon by 2030.

"The decision reflects Blue Origin's commitment to the nation's goal of returning to the Moon and establishing a permanent, sustained lunar presence," the company said in a statement.

Next-generation AI 'swarms' will invade social media by mimicking human behavior and harassing real users, researchers warn

Swarms of artificial intelligence (AI) agents could soon invade social media platforms en masse to spread false narratives, harass users and undermine democracy, researchers warn.

These "AI swarms" will form part of a new frontier in information warfare, capable of mimicking human behavior to avoid detection while creating the illusion of an authentic online movement, based on a commentary published Jan. 22 in the journal Science.

Imagine finding that the views of your favourite online community are hardening around a position that was previously up for debate. Human instinct is often to follow the "wisdom" of the herd. But in this case, the herd could be secretly shepherded by an AI swarm operating on behalf of an unknown individual, group, political party, company or state actor.

The hydraulic telegraph, invented by the ancient Greeks, had the capacity to send long-distance messages as early as the fourth century BC.

The ingenious apparatus is dubbed as the world's first telecommunications device. It was designed for military purposes by Aeneas Tacticus with the purpose of more efficiently sending pre-arranged messages across the vast empire of Alexander the Great.

Operation of the hydraulic telegraph is described in detail in Aeneas' work on sieges, Poliorcetika, which was retrieved by Polybius. The messages sent were along the lines of: "Enemy on sight," "Cavalry attack," "We need wheat," "Infantry in action," "Cyclical movement," and so on.

Astronomers spot 'time-warped' supernovas whose light both has and hasn't reached Earth

Will two rare supernovas finally tell us how fast the universe is expanding? Perhaps, but we'll have to wait for it for them to 'reappear'.

Two incredibly rare supernovas that erupted billions of years ago provide a unique opportunity to explain cosmology's biggest mystery โ€” How fast is the universe expanding?

But there's a twist: Even though astronomers have already observed these exploding stars, we will have to wait up to 60 years for their light to reach us again.

A phenomenon called gravitational lensing has split the light from these obliterated stars into multiple images, each of which travels a different path through space-time to reach us. As a result, researchers will one day be able to measure the delay between these ghostly images to offer an unprecedented constraint on the expansion rate of the universe โ€” a problem that has long bedeviled scientists, as the universe appears to be expanding at different rates depending on where they look.

Conor Larison, a postdoctoral researcher at the Space Telescope Science Institute, presented the discovery of the two gravitationally lensed supernovas, named SN Ares and SN Athena, at a news conference at the 247th meeting of the American Astronomical Society in Phoenix.

Marine sediments provide clues for future impact of climate change

Retreating Glaciers

An international team of scientists has uncovered evidence glaciers in the Southern and Northern hemispheres were synchronous during the last ice age.

The finding challenges prevailing theories and provides critical information to help model how today's ice sheets will respond to a changing climate.

Researchers from The University of Queensland, Ifremer, NIWA, the University of New South Wales, the Alfred Wegener Institute and CNRS, constructed the first complete record of glacial fluctuations in the Southern Alps of New Zealand by analysing a marine sediment core.

Professor Helen Bostock from UQ's School of the Environment said when the evolution of the New Zealand glaciers was compared to their European and North American counterparts, they were found to retreat simultaneously.

"Our work shows a period of global warming, likely caused by an increase in the global energy imbalance, preceded glacial retreats in both hemispheres at the same time," Professor Bostock said.

"The finding challenges previous theories of an inter-hemispheric 'bipolar seesaw'."

A team of Chinese researchers has developed an autonomous robotic system capable of performing delicate eye injections within the confined space of the human eye, potentially enhancing the precision and safety of surgeries used to treat debilitating retinal diseases.

The surgery robot, developed by a team from the Institute of Automation under the Chinese Academy of Sciences, successfully performed subretinal and intravascular injections in animal tests with 100 percent success, according to a study published recently in the journal Science Robotics.

Eye surgery, particularly involving the retina, is highly challenging due to the organ's tiny, soft structures. The new system uses a suite of algorithms for 3D spatial perception, cross-scale precise positioning, and trajectory control to guide a robotic arm.
