Tiny robots developed to help fix leaky water pipes
micro-robots
-- called
Pipebots
-- that can inspect water pipes, diagnose cracks and fix them autonomously that will help in reducing leaks, avoiding expensive excavation work and save time.
Currently, the only way to pinpoint the flaw is by humans digging and locating a leak in the maze of pipes, which can take days of searching, resulting in high costs and road closures that affect businesses and residents nearby.
In order to address this problem, researchers from the
University of Sheffield
's School of Mechanical, Aerospace and Civil Engineering, in collaboration with the universities of Birmingham, Bristol and Leeds, have developed a range of miniature robots with new sensors that can travel through pipes and check for defects autonomously.

The smallest robot measures 40 mm wide - similar to the size of a toy car. The bots are equipped with tiny, high-specification acoustic sensors and cameras, which enable them to navigate and detect faults freely, a statement from the University said here.
Without the need to dig up roads or pavements, a Pipebot swarm can be placed in a deployment hub and lowered into a water pipe through a hydrant by an engineer. The tiny patrollers will then explore the area, scan for faults, and relay data back to the engineer above ground, the researchers pointed out.

The Pipebots are equipped with all-terrain legs which enable them to navigate through any difficult paths they might encounter whilst underground, it said, adding, they can also talk to each other within a short range, so they can work together to carry out tasks and problem solve.

Professor Kirill Horoshenkov, Programme Director and Professor of Acoustics at the University of Sheffield, said: "
Leaky water pipes
are one of the biggest issues facing the water industry, not just here in the UK, but also globally as companies and governments grapple with ageing infrastructure."
"Whilst pipe inspection technologies have improved, it is still incredibly difficult to monitor the condition of water pipes and find leaks in these vast networks, especially when the leaks are small," he said.
He also gave examples of how the Pipebots can "significantly reduce the estimated three billion litres of water lost daily in England and Wales" and how such measures can save the UK economy's "part of the Pounds 4 billion lost annually due to utility street works and related disruptions."
Aside from water pipes, the bots are capable of operating in a range of other environments, including sewers, gas pipes and dangerous sites that are inaccessible to humans.
Professor Horoshenkov added: "The Pipebots project is a great example of the importance of collaboration between universities and industry."

Amazon reaches new milestone, becomes world's largest manufacturer and operator of…
Amazon has announced that it has reached a significant milestone, deploying its millionth worker robot across its global network of over 300 facilities. The company also revealed plans to power its entire robot fleet with a newly launched generative artificial intelligence (AI) model named " DeepFleet ." This expansion comes soon after company CEO Andy Jassy talked about job cuts and increasing automation. Amazon developing AI-powered robot fleet to boost efficiency According to Scott Dresser, Vice President of Amazon Robotics , this achievement solidifies Amazon's position as the world's largest manufacturer and operator of mobile robotics . Dresser stated that the new DeepFleet AI model will change how robots move within fulfillment centers, aiming to reduce fleet travel time by 10%. This efficiency gain is expected to lead to faster and more cost-effective package deliveries. Amazon began integrating robots into its operations in 2012, initially to transport inventory shelves. Since then, the roles of these automated workers have expanded, now including robots capable of lifting up to 1,250 pounds and fully autonomous units navigating facilities with customer orders. The company's continued investment in robotics and AI contrasts with some tech industry trends, though AI-powered humanoid robots are also anticipated to be deployed in Tesla factories this year. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Adidas Three Shorts With 60% Discount, Limited Stock Available Original Adidas Shop Now Undo Robots to work alongside humans: Amazon Dresser, while addressing anxieties about AI-led job cuts, emphasised that Amazon's robots 'work alongside our employees, handling heavy lifting and repetitive tasks while creating new opportunities for our front-line operators to develop technical skills.' He pointed to Amazon's new fulfillment center in Shreveport, Louisiana, which opened late last year and reportedly required 30% more employees in specialised roles like reliability, maintenance and engineering. However, Amazon CEO Andy Jassy recently told CNBC that the company's aggressive adoption of generative AI will inevitably lead to 'fewer people doing some of the jobs that the technology actually starts to automate.' While Jassy also stated that Amazon would continue to hire in AI and robotics, he admitted in an internal memo earlier this June that he expects the company's overall workforce to 'shrink in the coming years' due to technological advancements.

US stock market today: Wall Street edges higher as S&P 500 gains on Trump's Vietnam trade deal, Nasdaq jumps, Dow steady amid weak ADP jobs data
S&P 500 rises after Trump reveals Vietnam trade deal, but weak jobs data keeps gains in check- The S&P 500 rose on Wednesday following a surprise announcement from President Donald Trump about a new U.S.-Vietnam trade deal, which he shared via Truth Social. The benchmark index edged up 0.2%, driven by fresh hopes of improving global trade relations. However, the enthusiasm on Wall Street was held back by troubling labor market data. According to the latest ADP payrolls report, the U.S. private sector lost 33,000 jobs in June, the first monthly drop since March 2023, and far below economists' forecast of a 100,000-job gain. The Nasdaq Composite performed slightly better, climbing 0.7%, while the Dow Jones Industrial Average hovered near the flatline, reflecting mixed investor sentiment amid both positive trade developments and concerning economic indicators. US stock market today: S&P 500 rises, Dow gains, Nasdaq up ahead of key jobs report The US stock market showed mixed movements today, July 2, 2025, with the S&P 500 and Nasdaq Composite trading higher, while the Dow Jones Industrial Average saw modest gains. The markets responded to President Donald Trump's announcement of a Vietnam trade deal, alongside investor caution over weaker-than-expected private payroll data for June. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 청소년온라인상담사 자격증 390만원 환급 마지막기회! 청소년마음하나상담센터 더 알아보기 Undo Key index performance S&P 500 (via SPY ETF): 618.8 , up 0.2% Nasdaq Composite: +0.7% , helped by tech recovery Dow Jones Industrial Average: Up nearly 400 points or ~0.9% , led by industrials and materials Sector highlights and major movers Tesla stock surged nearly 6% after reporting 384,000 Q2 deliveries, beating expectations. Health-care sector dropped sharply, with one major provider falling around 40%, dragging others in the group. Materials and industrials stocks gained, as investors rotated away from tech and into value sectors. Economic data influencing the market ADP private payrolls report showed a decline of 33,000 jobs in June — the first monthly drop since March 2023. Economists had expected a gain of 100,000 jobs, leading to speculation about a potential Fed interest rate cut at the July meeting. Eyes are now on Thursday's official non-farm payroll report, forecasted to show 110,000 job gains and 4.3% unemployment. Market outlook: Federal Reserve decision on interest rates could shift if job data continues to weaken. Investors remain cautious, with stock indexes near all-time highs and macroeconomic uncertainty in focus. Trump's tax-and-spending bill, which just passed the Senate, is heading to the House and may influence fiscal policy outlook in the coming weeks. Tariff deadlines and ongoing geopolitical developments are also on the radar for market watchers. Live Events What does Trump's Vietnam trade deal mean for the U.S. stock market? President Trump's announcement of a new trade deal with Vietnam provided a brief tailwind to the S&P 500 and investor sentiment. Although the president did not offer details about the agreement, the post alone was enough to shift market focus from ongoing global economic uncertainty to potential international cooperation. This deal could mark a strategic step in balancing Asian trade relations, especially as tensions with China continue to weigh on global markets. However, without specifics, analysts remain cautious. Markets are looking for clarity—such as whether the deal covers tariffs, technology exchange, or broader economic cooperation. Why did job losses weigh on market optimism? The optimism sparked by Trump's trade news was tempered by a stark jobs report from ADP, showing that private payrolls declined by 33,000 last month. This marked the first negative reading since March 2023, and it shocked analysts, who had projected a gain of 100,000 jobs. Ross Mayfield, an investment strategist at Baird, told CNBC, 'We've been seeing a weakening of the labor market for months, and I always wondered if it would take a negative payrolls print to get the [Federal Reserve] to pay more attention.' His comment reflects growing concern that the Fed's focus on inflation may be overshadowing emerging cracks in the labor sector. Could weak employment data push the Fed to cut interest rates? Investors are now speculating whether Federal Reserve policymakers will shift course. A weak job market could become a trigger for a long-anticipated rate cut, especially as inflation pressures begin to cool. The CME Group's FedWatch tool now shows a 25% chance of a July rate cut, up from 20% just the day before. Sam Stovall, chief investment strategist at CFRA Research, believes that a softer jobs report could clear the path. 'If we end up having a fairly weak employment report, then that could allow the Fed to be cutting rates,' he said. Stovall also pointed out that Fed Chair Jerome Powell had previously mentioned that the central bank would have already cut rates if not for Trump's earlier tariff plans. How are markets reacting ahead of the official jobs report? Despite Wednesday's ADP data, traders are now looking ahead to Thursday's official government jobs report. Economists are forecasting a gain of 110,000 jobs for June. However, if that figure misses the mark in a similar way to ADP's number, markets may begin pricing in more aggressive Fed action later this month. This comes as stocks flirt with record highs, making them particularly sensitive to economic data and Federal Reserve decisions. Wall Street's mixed performance—where the Dow surged 400 points on Tuesday while tech-heavy indexes fell—suggests a market still unsure about its direction. What other political developments are influencing Wall Street? In addition to the trade announcement and economic data, investors are watching Trump's tax-and-spending bill, which narrowly passed the Senate on Tuesday. The measure now returns to the House, where some GOP lawmakers remain opposed. The bill could have broad implications for sectors like infrastructure, healthcare, and manufacturing, depending on how funds are allocated. Meanwhile, the market has seen a rotation out of technology stocks and into more defensive sectors such as materials and healthcare, signaling that investors are bracing for potential economic headwinds. Today's US stock market at a glance Index Move Today S&P 500 +0.2% Nasdaq +0.7% Dow Jones +0.9% (~400 pts) Tech stocks recovered, led by Tesla Health-care stocks under pressure Investors watch job data and Fed signals closely What should investors watch now? S&P 500 rose 0.2%; Nasdaq gained 0.7%; Dow was flat. President Trump announced a new U.S.-Vietnam trade deal, but offered no specifics. ADP report showed 33,000 private jobs lost in June, vs. 100,000 expected. Fed may consider interest rate cuts if Friday's official jobs data also disappoints. Trump's tax bill passed Senate, still faces GOP resistance in House. With Trump's trade diplomacy making waves and labor market signals flashing warning signs, all eyes are on the upcoming jobs report and the Federal Reserve's July policy meeting. The next few days could shape the trajectory of both the stock market and U.S. economic policy for the rest of 2025. FAQs: Q1: Why did the S&P 500 rise after Trump's Vietnam trade deal? Because investor sentiment improved after Trump revealed a new trade agreement with Vietnam. Q2: Could weak jobs data lead to a Fed rate cut? Yes, a drop in payrolls could push the Fed to lower interest rates this month.

Microsoft layoffs hit 9,000 in new round, job cuts span teams and locations - here's who's affected
Microsoft layoffs 2025 : Why the tech giant is cutting 9,000 jobs despite strong profits- Microsoft layoffs 2025 have once again raised eyebrows across the global tech community. On Wednesday, Microsoft announced it would lay off around 9,000 employees, affecting less than 4% of its global workforce. The decision comes just as the company steps into its fiscal year 2026, marking yet another wave of job cuts in an already turbulent year for the tech industry. While the company didn't officially confirm the exact figure publicly, a source familiar with the matter told CNBC that the move spans across multiple departments, regions, and experience levels. This round follows earlier layoffs in January, May, and June, signaling deeper restructuring within the company. How big is this layoff compared to Microsoft's workforce? Microsoft currently employs around 228,000 people globally . With 9,000 roles now being eliminated, this round alone impacts roughly 3.9% of the entire workforce . by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like War Thunder - Register now for free and play against over 75 Million real Players War Thunder Play Now Undo This follows earlier cuts in: January 2025 : ~1% of staff May 2025 : ~6,000 employees let go June 2025 : ~305 employees affected When combined, Microsoft has cut over 15,000 roles in just the first half of 2025. Live Events Why is Microsoft laying off 9,000 workers when it's making billions? This latest Microsoft layoff round in 2025 is part of a broader effort to streamline operations and reduce management layers. A spokesperson said via email, 'We continue to implement organizational changes necessary to best position the company and teams for success in a dynamic marketplace.' Despite the job cuts, Microsoft is far from struggling. The company posted $26 billion in net income on $70 billion in revenue for the March quarter. These numbers far exceeded Wall Street estimates, making Microsoft one of the most profitable firms on the S&P 500. Still, internal shifts are happening. Like in May, Microsoft aims to flatten its hierarchy by trimming the layers of management between senior executives and day-to-day contributors. Which Microsoft teams are impacted the most? The Microsoft Gaming division, including Xbox, King, and ZeniMax, faces the brunt of the layoffs. King, the mobile game studio behind Candy Crush , is cutting around 200 roles, representing about 10% of its team. ZeniMax Europe and other regional offices are also seeing reductions. Internal sources confirm that multiple departments across product development, design, marketing, and support are being downsized or consolidated. In an internal memo, Xbox chief Phil Spencer wrote: 'To position Gaming for enduring success, we will end or decrease work in certain areas of the business and remove layers of management to increase agility and effectiveness.' Sales, marketing, and middle management also targeted Beyond gaming, significant layoffs are hitting Microsoft's Sales and Marketing teams, especially in: U.S. regional offices European marketing units Mid-level management and operations staff This aligns with Microsoft's broader AI-first strategy, which includes: Streamlining organizational layers Automating functions through AI tools like Copilot Investing in AI sales enablement rather than traditional staffing Where are the layoffs taking place? While the layoffs are global, certain patterns are emerging: U.S. teams, particularly in Washington and California, have been hit hard. European subsidiaries, including ZeniMax offices, are undergoing restructuring. India operations remain untouched, as Microsoft has committed a $3 billion investment in AI infrastructure and hiring in the region. This geographic targeting signals Microsoft's pivot toward low-cost, AI-driven hubs in Asia. Microsoft says the layoffs are part of a strategic realignment to focus on artificial intelligence, efficiency, and long-term innovation. Key motivations include: $80 billion investment into expanding AI capabilities and data centers globally The need to flatten management hierarchies to become more agile Reallocation of resources toward AI product development, cloud infrastructure, and strategic growth markets An internal Microsoft source stated: 'AI is driving how we think about teams. We want fewer layers, more execution.' How is Microsoft stock reacting to the layoffs? Following the announcement, Microsoft shares dipped by around 0.6% during early Wednesday trading. In comparison, the S&P 500 remained flat. The slight drop may reflect short-term investor reactions, but not necessarily long-term concerns. Even with the layoffs, Microsoft's core business remains strong. Its cloud platform, Azure, and productivity tools like Office 365 and Teams are driving projected 14% year-over-year revenue growth in the June quarter, according to executives. Are other tech companies also laying off workers in 2025? Yes, Microsoft isn't alone in making workforce cuts in 2025. Several major players in the tech and software industry are also streamlining: Autodesk Chegg CrowdStrike Additionally, ADP (Automatic Data Processing), a leading payroll services firm, revealed on Wednesday that the U.S. private sector lost 33,000 jobs in June, contradicting economists' expectations of 100,000 new jobs, according to a Dow Jones survey. What's the bigger picture for tech jobs in 2025? This year continues a broader trend of tech companies restructuring and optimizing operations. With AI growth, cloud expansion, and shifting remote work dynamics, companies like Microsoft are reevaluating how to stay lean and efficient while keeping innovation alive. While layoffs are painful and disruptive, especially on such a large scale, they reflect how businesses are adapting in a fast-changing digital economy. The Microsoft layoffs of 2025 show how even the most successful tech giants are making tough decisions amid strong financial performance. With over 9,000 jobs cut this time, it's clear that organizational reshaping, not financial distress, is the driving force. As more tech companies follow similar paths, the landscape for software jobs is shifting—and professionals will need to adapt just as quickly. Stay tuned for updates as more details unfold around team-specific impacts and future hiring trends in the tech industry. FAQs: Q1: Why is Microsoft laying off employees in 2025? Microsoft is cutting jobs to restructure teams and reduce management layers. Q2: How many people has Microsoft laid off this year? Microsoft has laid off over 15,000 employees in 2025 so far.
