Bronze swords made from copper and tin aren't the most robust of weapons, and cannot be repaired easily. This has led to some uncertainty about whether weapons like swords, shields, and arrows made from these materials can survive battles. Some even claim that these weapons were used in celebrations, not in clashes.

An international team including researchers from the UK, Germany, and China has put an end to this uncertainty by creating seven middle to late Bronze Age swords using traditional methods, then tested them out in a simulated historic battle in which ancient bronze swords were used.

By analyzing the marks and indents left on the weapons by the mock battles, and comparing them with a study of 110 ancient Bronze Age swords (3000 BC – 1200 BC) found across Great Britain and Italy, the team was able to show that these weapons weren't just ceremonial items. The team announced their findings in the Journal of Archaeological Method and Theory.

This isn't the first study to explore the use of such weapons in wars, but it is the first to support its hypothesis with mock battles in which the researchers highlighted how combat marks got left on weapons, how swords would've been held in battle, and even the sorts of body areas that fighters would've aimed for.

What's more, by looking at differences between sword wear and tear across the centuries, the researchers were able to map out evolution in sword fighting, an early battling method across Britain and Italy.

In a report published on the Science Alert website, Archaeologist and Senior Author Barry Molloy from City University College Dublin in Ireland said: "One limitation of the study is the fact that we still know so little about how people fought in the Bronze Age. For the battle experiments, we recreated medieval (5th to 15th century CE) battles, as these are the techniques best described in the literature."

"It's hard to know whether the tests performed were accurate representations of how the blades would have been used, but at least we were able to demonstrate that bronze weapons were skillfully used in wars," he added.

More than half a century ago, a Hungarian architect, sculptor and professor invented what would become one of the world's most popular and beloved puzzles whose appeal has spanned generations: the colorful, mind-bending, six-sided Rubik's Cube.

Now, after selling more than half a billion units and becoming a worldwide cultural touchstone, production of the cube is returning to Hungary, where its inventor, Ernő Rubik, first conceived of the iconic object that bears his name.

Hungary “is the home of the cube. The cube was born here,” Rubik, 82, said on Tuesday at the opening of a new, fully automated Rubik's Cube production line in the Hungarian city of Jászberény.

The journey of the Rubik's Cube began in 1974, when Rubik was teaching design at the Academy of Applied Arts and Design in Budapest. Seeking to create a three-dimensional object that was “infinite,” he said, he completed a prototype — then made of wood — of a cube that could rotate on multiple axes and was made up of 27 blocks.

Recognizing its consumer value, Rubik soon began producing more of the puzzles. Beginning in 1977, an initial 5,000 units of what was then called the “Magic Cube” were sold at specialty shops in the Hungarian capital.

The invention — or what Rubik prefers to describe as a “discovery” — gained popularity, and after having difficulties procuring materials for the cubes in then-socialist Hungary, he realized: “We were not prepared for that size of production ... We can’t fulfill the needs of the market worldwide.”

The cube was licensed to a British and then a US toy company, and its production was moved abroad. By the early 1980s, its popularity had exploded in what Rubik called “the first big wave,” in which he said 200 million units were sold between 1980 and 1983.

While sales of the cube dipped after its initial success, it still attracts plenty of users eager to try their hand at solving the puzzle. Millions are sold every year.

At the new production line in Hungary, a series of robotic arms assembles the cubes and tests them for functionality and durability — a level of automation Rubik said was “very different” than in the early days when the cubes were assembled by hand.

The new line in Jászberény plans to produce 1 million cubes annually.

Steve Radewych, a senior vice president with Canadian toy company Spin Master, which owns the Rubik's Cube trademark, said at Tuesday's opening that the theme of the day was: “Back to its roots: The cube comes home.”

“Ernő, your discovery is more than a toy,” Radewych told Rubik. “It's a global social phenomenon.”

Radewych noted the “incredible staying power” of the Rubik's Cube, and the fact that the puzzle continues to hold the fascination of young people even today.

“The cube represents an intellectual journey, a symbol of intelligence, problem-solving and cognitive discipline,” he added, which “has brought joy — and frustration — to many generations.”

The cube has enjoyed another surge in popularity in recent years as global competitions have proliferated, measuring who can solve the puzzle the fastest.

The current record, set only last month in China by nine-year-old Xuanyi Geng, is 2.51 seconds, according to the World Cube Association, which organizes and certifies competitions across the world.

Rubik, who does not consider himself a speed competitor, said that for him, the cube represents a “transformable sculpture,” the place where art and engineering meet and users can manipulate and change the cube in nearly endless variations.

“If you are doing something, creating something, you have the chance to do something that is meaningful — that’s one part — and beautiful,” he said.


SpaceX Starship Test to Attempt First-Ever Spaceship ‘Catch'

Elon Musk's SpaceX was poised Friday to carry out its latest test of the world's biggest and most powerful rocket, the Starship, with plans for a groundbreaking "catch" of the spaceship following a day in orbit.

A successful capture of the Starship upper stage would mark a significant milestone in the space industry's decades-long pursuit of fully reusable spacecraft that can drastically reduce mission costs and make frequent travel possible.

"If successful, this will mark the first full recovery of an orbital launch system and a breakthrough moment in making Starship a reliable, rapidly reusable rocket," SpaceX said.

For the 15th Starship test flight Friday, SpaceX aims to recover both stages of the massive 124-meter (407-foot) launch vehicle.

The company has caught the booster, dubbed Super Heavy, on three previous occasions, with the first stage descending vertically back to the launch site shortly after blastoff and nestling into mechanical "chopstick" arms.

It will now attempt to do the same with the spaceship. Some versions of the vessel are designed to launch internet satellites and data centers into orbit, while others will be made to ferry people to the Moon and Mars.

A spacecraft that can be fully reused is the "Holy Grail" of the space industry, said Clayton Swope, an aerospace expert at the Center for Strategic and International Studies.

"No one's really been able to do that so far," he said. "People have been trying to do that since the (NASA) space shuttle. But the space shuttle ended up being kind of a compromise because a lot of the vehicle wasn't reusable."

Reusing the Starship spacecraft would require the vessel to withstand the extreme heat of reentering Earth's atmosphere and then return to service without extensive refurbishment.

- Refueling challenge -

Musk, the world's richest person, has already revolutionized the space sector with the partially reusable Falcon rockets, which are regularly employed to launch satellites and carry astronauts to the International Space Station.

The Starship project, however, has been plagued by years-long delays as SpaceX grapples with novel engineering challenges -- even as NASA is counting on the spaceship to serve as a lunar lander for its Artemis program.

Other technical challenges include transferring fuel to Starship in orbit -- a requirement for any journey to the Moon or Mars.

Following SpaceX's high-profile stock market debut in June, the company carried out the first orbital flight of Starship in September, though the mission was cut short due to an engine issue.

It is also investing heavily in additional launch sites for its mega-rocket in Louisiana and Florida.

- Complex capture -

Friday's launch is scheduled to take place at SpaceX's "Starbase" in southern Texas at 4:45 pm (2245 GMT).

Following liftoff and the mid-air separation of the two stages, SpaceX plans to bring Super Heavy back to Earth six and a half minutes later, catching it at the launch site on the Gulf of Mexico coastline.

The spaceship will continue to reach Earth's orbit, where it will deploy 26 satellites into Musk's Starlink satellite internet constellation that has become a major revenue stream for SpaceX.

It will then circle the planet 14 times, before returning 22 hours later and -- SpaceX hopes -- descending safely into the chopstick arms.

This capture attempt is more complex than that of the booster, as the spaceship will be descending much faster and from a much greater altitude.

SpaceX has said it would proceed with these maneuvers only if conditions are optimal, and in the past has made last-minute changes to test flights under Musk's "fail fast" strategy of learning through crashes, explosions and other mishaps.

As of late Thursday, the US Federal Aviation Administration had not yet given its final approval for the test flight.

India's capital Delhi overtook Lahore in Pakistan to become the world's most polluted city on Friday, with air quality reaching hazardous levels and visibility dropping as smog blanketed the city of 20 million people.

Air quality index (AQI) in Delhi was "hazardous" at 334, making ‌it the ‌most polluted global major ‌city, ⁠according to Swiss group ⁠IQAir, which measures air quality levels based on the concentration of toxins.

An AQI reading up to 50 is considered good with little or no ⁠health risk.

India's official ‌Central Pollution ‌Control Board pegged the AQI higher at ‌403 and rated it "severe".

The ‌Swiss and Indian readings vary due to the different AQI scales and methodologies used to calculate and ‌classify air pollution levels.

Cars and motorcycles emerged from dense ⁠smog, ⁠which also appeared to obscure streetlights on the city's main roads, videos from news agency ANI showed.

Pollution is a seasonal problem in many parts of northern India and neighboring Pakistan, as the cold, heavy air of winter traps vehicle emissions, construction dust and smoke from agricultural burning.
