Watch: This Robot Can Solve Rubik's Cube Before You Might Blink
A group of students at Purdue University, Indiana, USA, have smashed the previous Guinness World Record of solving a Rubik's cube once held by Mitsubishi, a Japanese conglomerate worth nearly $80 billion. The high-speed robot is called the Purdubik's Cube, which managed to solve the puzzle cube in a blink-it-and-you-miss-it 0.103 milliseconds.
Matthew Patrohay, the lead of the project, was inspired by the previous record holder and wanted to make his own attempt at the record. After gathering his friends, Junpei Ota, Aden Hurd, and Alex Berta, the team managed to beat Mitsubishi's record by two-tenths of a second.
"To put it in perspective, the human blink is 200 to 300 milliseconds. So we're significantly faster than that. Human reaction time is about .200 milliseconds as well, so we're faster than that," said Mr Patrohay.
Talking about the challenges in developing the machine, the researchers said they had to redesign the cube so that it could withstand the tremendous force required to solve it within milliseconds.
'The cubes themselves just disintegrate,' said Mr Patrohay. 'The pieces themselves snap in half and fall apart.'
Social media reacts
The video of the machine in action has gone viral on social media, inviting puzzled reactions from the users, who cannot believe the cube was solved in a blink.
"WOW. I literally blinked and missed it the first time. Absolutely insane," said one user while another added: "I had to watch it a couple of times because it looked like they just clipped it to show the finished cube."
A third commented: "It is even more impressive to me that they built a cube capable of being solved that quickly without disintegrating."
NEW: Purdue students demolish the Guinness World Record for fastest Rubik's cube-solving robot, solving the puzzle cube in just 0.103 seconds, faster than the blink of an eye.
Insane.

The rapid machine was first unveiled at SPARK, Purdue's Electrical and Computer Engineering (ECE) student design competition, where it took home first place in December 2024. The team continued to build on the success by pushing the limits of automation and high-speed computing.
The achievement is made more remarkable by the fact that Purdubik's Cube is highly intuitive and interactive. Using a Bluetooth-enabled "Smart Cube," users can scramble the puzzle in real time, and the robot mirrors every move, solving the cube instantly once the scramble is complete.

This $7,000 single-seat electric car is a big hit in Japan
In the rural suburbs of Hiroshima, a Japanese startup is trying to kick start the nation's electric vehicle market with the smallest, cheapest car it can possibly make. KG Motors has developed a battery-powered one-seater that more resembles a futuristic golf cart than it does a modern EV, much less a traditional car. And yet well over half of the 3,300 units it plans to deliver in 2027 have already been pre-sold to customers. Incidentally, that puts it on track to sell more EVs in Japan than the world's biggest automaker, Toyota Motor Corp., which shifted around such 2,000 vehicles in all of 2024. In a country where EVs are still a rare sight, KG Motors is trying to bust a burgeoning myth: that bigger is better. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Villas For Sale in Dubai Might Surprise You Dubai villas | search ads Get Deals 'Cars are simply too big,' founder and Chief Executive Officer Kazunari Kusunoki said. 'Seeing so many big cars traveling Japan's narrow streets – that's where this all began for me.' At under 1.5 meters in height, KG Motors' mibot has a range of 100 kilometers (62 miles), a charging time of five hours and a top speed of 60 kilometers per hour. It will cost ¥1 million ($7,000) before tax when production starts in October at KG Motors' new factory east of the city. That's about half the price of Japan's most popular EV, Nissan Motor Co.'s Sakura. Live Events To date, domestic and foreign automakers alike have struggled to find traction for EVs in Japan. The cars accounted for about 140,000 units or around 3.5% of total vehicle sales in 2023, a far cry from the global average of 18%, according to BloombergNEF. Chinese behemoth BYD Co., for example, sold 2,223 automobiles in Japan in 2024 – a sliver of the 4.3 million it delivered worldwide. Toyota and its Japanese peers, meanwhile, are at odds with other legacy automakers that hold an all-electric view of the future. Toyota has long harbored a multi-pathway approach to a greener tomorrow, one where EVs as well as gasoline, hybrids and hydrogen-powered vehicles play a role. As a result, the gas-electric hybrids pioneered by Japanese manufacturers still dominate. 'Toyota said EVs aren't the only solution and, because it's Toyota, Japanese people assume it must be true,' Kusunoki said. 'A large number of people in Japan seem to believe EVs won't become popular.' Japan, at least, has been slower to embrace the global trend toward larger, roomier vehicles. Smaller autos have always been a feature in the Asian nation and its lightweight kei cars have even found cult followings abroad. In recent years, they've claimed the lion's share of the domestic EV market, accounting for 55% of total sales in 2023. Nissan's Sakura is a kei car, with just under 23,000 units sold in 2024. In April, BYD said it's planning to produce a fully-electric kei car specifically for the Japanese market in the second half of 2026, while Hyundai Motor Co. introduced the Inster earlier this year, a ¥2.9 million vehicle it claims to be Japan's cheapest EV, at least among full-sized passenger cars. Small-sized EVs have helped spark consumer acceptance of battery-powered cars overseas as well. In China, the world's biggest EV market, SAIC-GM-Wuling Automobile Co.'s Hongguang Mini was at one point the nation's top seller. Still, with its single-seat design, KG Motors' mibot is in a tiny league of its own. The first 300 should be delivered to customers in Hiroshima and Tokyo by the middle of next year, while the next 3,000 will be shipped nationwide, Kusunoki said. KG Motors says it will lose money on the first batch but should break even on the second. After that, the company aims to produce around 10,000 units annually. It's in the process of acquiring the vehicle safety certification needed to commercialize the mibot. The startup's size and make-to-order strategy could work in its favor. EVs use far less parts than conventional gasoline or hybrid vehicles but the mibot takes that to another level, essentially consisting of a battery, motor and sparse electronics connected by wiring housed within a monocoque chassis on four wheels, so production costs are low. Even KG Motors' marketing draws on Kusunoki's former life as a YouTube content creator. The company has published footage on its website of the mibot being tested on the icy roads of Hokkaido, squeezing between homes packed into Hiroshima's historic districts and smashing into concrete walls at high speeds to ensure it satisfies Japan's strict safety regulations. Kusunoki, 43, who founded KG Motors in June 2022, grew up in Higashihiroshima, a suburban town with streets sometimes too narrow even for a Japanese sedan. He watched the country's public transport infrastructure deteriorate as a shortage of taxi drivers was compounded by an aging, shrinking population. As young people migrate to big cities, it's also becoming more difficult for the elderly to get around. As a result, KG Motors ultimately sees demand for one- or two-seater compact, cost efficient cars. As of early May, the company had received 2,250 orders, with over 95% coming from homeowners with at least one vehicle. 'In rural parts of the country, public transportation systems are in shambles,' Kusunoki said. 'This might be hard for someone living in Tokyo to understand but at some point, it becomes necessary to have one car per person, not just per household.'

8 per cent infectious disease outbreaks during 2018-2023 spread from animals to humans, study says
Zoonotic outbreaks consistently peaked during June, July, and August, researchers from the Indian Council of Medical Research-National Institute of Epidemiology, Chennai said. Typically, about seven zoonotic outbreaks -- also sometimes called 'spillover events' -- occurred in a month, and such instances significantly increased over the years, specifically, post-pandemic, the study published in The Lancet Regional Health Southeast Asia journal found. Study highlights The team analysed a total of 6,948 outbreaks reported under the Integrated Disease Surveillance Program (IDSP) to identify trends. Of these, 583 (8.3 per cent) were zoonotic -- Japanese encephalitis was found to account for 29.5 per cent of zoonotic outbreaks, followed by leptospirosis (18.7 per cent) and scrub typhus (13.9 per cent). Region-wise, the northeast part of the country contributed 35.8 per cent of zoonotic disease outbreaks, followed by the southern (31.7 per cent) and western regions (15.4 per cent), the researchers found. They added that late reporting of disease outbreaks has declined over the years -- 52.6 per cent in 2019, 40.9 per cent in 2021, and 5.2 per cent in 2023. Overall, a third of the outbreaks during the study period were reported late, the team said. "Of the 6948 outbreaks reported in IDSP, 583 (8.3 per cent) were zoonotic, with a median of seven monthly zoonotic outbreaks. Outbreaks significantly increased over the years," the authors wrote. Further research required The researchers said that while outbreaks of measles, chickenpox, and dengue have been individually analysed, zoonotic events from the national-level infectious disease surveillance system have not been comprehensively examined. A lack of analysis of geographical patterns and documentation of reporting delays hindered evidence-based decision-making and targeted interventions, the team said. "Critical gaps in weekly outbreak reports were identified, particularly the lack of follow-up documentation. To address these gaps, we recommend strengthening disease-specific surveillance systems in hotspot regions," the authors concluded.
