One year on from the first-ever collisions of oxygen at the Large Hadron Collider (LHC), the main LHC Collaborations – ALICE, ATLAS, CMS and LHCb – have each reported signs of the state of matter known as quark–gluon plasma (QGP) originating from these collisions.

QGP is a state of matter that forms under intense pressure and at temperatures over 100 000 times hotter than the centre of the Sun. Under these extreme conditions, composite particles break down into quarks and the gluons that ordinarily hold them together. Scientists believe that this was the state of the Universe in the first millionths of a second after the Big Bang...

It was previously thought that colliding heavy ions such as lead – which is over 200 times heavier than the protons typically collided at the LHC – was the only way to create the conditions necessary to form QGP. But recently this premise has been thoroughly challenged, including earlier this year when the ALICE Collaboration, which specialises in the study of this extreme state of matter, reported a new sign of QGP from proton–proton and proton–lead collisions. And last year, the LHC Collaborations opened up a new probe of QGP when they found the first hints of QGP from oxygen–oxygen collisions. Now, having searched even more deeply, the LHC experiments have seen multiple signs of QGP formation in oxygen–oxygen and neon–neon collisions...

...The Ukrainian defense ministry reported that the drone is highly maneuverable and provides precise and smooth control at various speeds.

The Cyclops UAS was developed by a Ukrainian company. The system has several variants.

The first variant is less expensive, simpler in design, and easier to operate. These are designed to engage ground targets, as well as slow-moving aerial targets at low altitudes.

The second variant has significantly higher tactical and technical characteristics and is designed to effectively engage high-speed Shahed drones at high altitudes...

..."Eventually, we need some form of universal basic income for everybody while they work and once they retire," Roubini added. "We're already on the way."...

"We'll have either ex-post distribution—that is universal basic income—or we'll have it ex-ante. Ex-ante means some form of socialism," Roubini explained. "Essentially, the government is going to take over some fraction of the big tech firms."

He said AI companies are already willing to hand over stakes to the government, alluding to a Financial Times report that said OpenAI has discussed giving 5% as a way for the public to share in the upside of AI.

Altman's proposal would entail other AI companies providing similar stakes, although it's not clear if his U.S. rivals would be willing to do so.

As a result, Roubini believes universal basic income or socialism is inevitable, saying "We're going already in that direction, effectively."...

...he called it optimistic, given that it assumes 10% growth and "machines doing all the work."...

...the fires destroyed thousands, or even tens of thousands, of items belonging to sellers who work through Wildberries, Russia’s largest online retailer. Very rough, preliminary estimates put the damage at more than 50 billion rubles. Up to 15% of the company’s total warehouse space may have been affected...

Social media users have pointed out that Wildberries does in fact sell war-related goods, including body armor, combat helmets, camouflage uniforms, and fiber-optic cable for drones...

The Kotovsk warehouse opened in late May 2025 and plays an important role in regional logistics. The center can store up to 54 million items. At the opening, Kim said:

"Building a logistics center in Tambov Oblast will help optimize existing routes, significantly reduce costs and transit times for transportation, storage, and delivery of goods. In addition, having a logistics center will help local entrepreneurs develop small and medium-sized businesses by giving them the ability to store, distribute, and ship goods to other cities."

...In early July, Wildberries added a clause to its seller agreement exempting the company from any liability in the event of a drone attack. The amendment took effect on July 7 — 11 days before Ukraine’s strike on the warehouses...

"Today it wasn’t just goods that burned. Another illusion burned — that someone would protect entrepreneurs. The rules are changing. The risks are being shifted onto us. The losses are becoming ours too. It’s only going to get worse. Something urgently needs to change, radically."

...One of the challenges of clean energy is transporting and storing massive amounts of solar and wind power over long distances...

According to the new study, pulverized iron powder could act as a highly efficient, recyclable clean energy storage material...

The concept taps into a beautifully simple chemical loop. When iron powder is combusted, it releases intense heat and turns into iron oxide. In other words, it rusts. To reset it, scientists use green hydrogen generated from excess renewable energy to strip away the oxygen, reducing the rust back into pure iron powder. No carbon dioxide escapes into the atmosphere. The cycle simply repeats...

As it burns similarly to fossil fuels, energy giants wouldn’t need to rebuild their infrastructure from scratch...

The expensive components already in place, such as the steam cycles, massive turbines, heavy generators, and local grid connections, could be fully preserved...

..."Once you have super-conducting technology available in space, you can then create very strong magnetic fields and you can use them for various use cases," he said. "You can accelerate things in space very fast or change the trajectory of a satellite completely without fuel."...

"When we go to space, we get hurt by radiation, and these superconducting magnets can create umbrellas of magnetic fields around the spacecraft to protect the interior," said Arshavsky. "So we can shield people in space from that radiation."...

...a Yale-led team measured the internal motions of a faint, diffuse galaxy called NGC 1052-DF9 and found its stars moving too slowly to hide a normal dark matter halo. The galaxy joins two earlier oddballs, DF2 and DF4, and all three lie along the same narrow line of galaxies in the NGC 1052 field...

A few years ago the same group noticed that DF2 and DF4 were not alone. About a dozen faint galaxies in the field fall along a remarkably tight, straight trail, and follow-up work showed their velocities increase steadily along its length...

That geometry points to a specific and dramatic origin. In one leading idea, two gas-rich galaxies slammed into each other at high speed long ago. The dark matter of each passed straight through, because dark matter barely interacts with anything, while the ordinary gas piled up, shocked and compressed, and later collapsed into a string of small galaxies made almost entirely of normal matter...

...The finding is that DF9’s motion is consistent with its stars alone and inconsistent with a full dark matter halo. That is not the same as proving the halo is exactly zero. A modest amount of dark matter still fits inside the error bars; a normal amount does not...

The deeper reason astronomers care is almost the opposite of what the headline suggests. Finding galaxies without dark matter is, oddly, some of the better evidence that dark matter is real. If gravity simply behaved differently in faint galaxies, as some alternative theories propose, then every galaxy of a given size should show the same anomaly. Instead a few galaxies, all apparently born in the same collision, stand out from thousands of ordinary ones. Dark matter that can be left behind in a crash is dark matter that exists as a substance, not as a quirk of the equations...

...After a long, challenging cruise phase with nine planetary flybys (one by Earth, two by Venus and six by Mercury), BepiColombo finally closed this chapter last Monday by permanently switching off its SEP thrusters...

Without any other source of propulsion, BepiColombo will follow a “ballistic” or free-falling trajectory as it initiates its first key arrival manoeuvre – MTM separation – on 3 September 2026.

After the MTM is ejected, the remaining spacecraft composite (MPO-Mio-MOSIF) will continue its planetary approach using MPO’s chemical propulsion system. This system will adjust the spacecraft’s trajectory ahead of the critical Mercury orbit insertion manoeuvre on 21 November, then guide it into Mio’s deployment orbit in early December before finally lowering MPO into its science orbit by March 2027...

In 2025, astronomers reported one of the largest rotating structures ever found: a cosmic filament some 50 million light-years long, holding close to 300 galaxies, with many of them turning in step with the filament as a whole. The coordinated motion is difficult to reconcile with the way galaxies are thought to acquire their spin...

Galaxies are thought to get their spin early, through what is called tidal torque: as matter collapses under gravity, the uneven pull of its surroundings sets it turning. On that picture, a galaxy’s spin is shaped mostly by its own local patch of the universe, and there is no obvious reason for hundreds of galaxies, spread across tens of millions of light-years, to share a single coordinated rotation tied to the filament around them...

The question underneath is an old one, which is where galaxies get their angular momentum. This filament has not answered it, but it has handed the problem a large and awkward new clue.

...In May 2026, a team of researchers reported evidence for primordial black holes (PBHs) by spotting a short-lived flicker of light from a star in the Large Magellanic Cloud. They monitored millions of stars in this galaxy using DECam. They spotted one star that briefly brightened for less than an hour. They interpreted this as a gravitational microlensing event. Microlensing occurs when a tiny object passes in front of a star and its gravity briefly bends and magnifies the star's light like a lens.

Because the brightening was so short, they calculated the "lens" causing it must have had about the mass of the moon. This one-time, nonrepeating signal was interpreted as a microlensing event caused by a primordial black hole nicknamed "Phoebe."...

In this new study, Udalski and Mr.óz present an independent analysis of the same public DECam data, plus extra observations from 2020 and 2021 that the previous paper didn't include.

They found that the star brightened at least three separate times over the years—one of which was previously interpreted as a microlensing event. In addition, its average brightness also changed over time...

"This is not the first time that a variable star has been mistaken for a short-timescale microlensing event in high-cadence time-series observations of limited duration," the researchers note. Short-term monitoring lasting some days, they explain, simply isn't enough to tell the difference. Distinguishing a genuine one-time gravitational event from a star's natural flickering requires months or years of monitoring.

...In 2013, a team of anthropologists led by Lee Berger unearthed the remains of more than 20 small-bodied hominins (ancient relatives of humans), all 335,000 to 236,000 years old, from the Rising Star Cave System in South Africa. Excavations at Rising Star have sparked debate about whether these little hominins had all ended up in the caves by tragic accident, or whether they’d been carefully placed there by other members of their enigmatic species, dubbed Homo naledi.

Now there’s a plot twist that may speak to how the remains got there: All of the hominins in Rising Star are female, at least according to the proteins in their dental enamel...

There’s an ongoing debate about Neanderthal art and abstract thought despite a growing pile of evidence. And that sort of debate rises in intensity when the early hominins in question have brains as relatively small as Homo naledi’s, which is about the size of a chimpanzee’s.

“There is a divide in the field between those that think that humans evolved from cultural species that were before us, and those that believe that culture originated with modern humans,” says Hawks, “so they resist any claims of culture earlier unless they have some sort of extraordinary evidence.”...

“This is our first contact with a—and I think it’s important to repeat this—a non-human species. Their brains are not human brains,” says Berger. And he’s deeply concerned about how humanity navigates that first contact.

...no other hominin species, meaning none of the Australopithecines and not even Homo erectus, have presented us with such clear evidence that they tended to their dead and etched art or symbols on the cave walls nearby. In other words, Homo naledi might have thought and felt in ways that we have to recognize as on a level with our own cognition...

...He hopes the protein study will prompt anthropologists and Homo sapiens in general to seriously think about the ethics of digging up the graves of an intelligent and cultured but non-human species.

“It certainly will mean we have to stop digging hominins like dinosaurs,”...

...The discovery expands how motors and actuation systems can be designed. Most electromagnetic motors today depend on magnets and copper coils. This new approach can create motion without magnets or rare earth metals, which could be valuable in a world where material resources are limited.

The design could also be lighter and simpler. Since the rotating component can be made from resin instead of metal, devices may become lighter and faster to respond. That could help in robotics, compact machines, and precision systems.

Because the motor does not depend on magnetic fields, it may also work well in places where magnetic noise causes problems, including medical equipment and data storage devices...
