Snowcap Compute raises $23 million for superconducting AI chips
SAN FRANCISCO :Snowcap Compute, a startup working on building artificial intelligence computing chips using superconducting technology, on Monday raised $23 million and said that the former CEO of Intel will join its board.
Snowcap aims to build computers that could one day beat today's best artificial intelligence systems, while using a fraction of the electricity. To do that, Snowcap plans to use a new kind of chip made with superconductors, which are materials that allow current to flow without electrical resistance.
Scientists understand superconductors well and have theorized about making computer chips with them since at least the 1990s, but have faced a major challenge: To work, the chips need to be kept very cold in cryogenic coolers which themselves consume a lot of electricity.
For decades that made superconductor chips a nonstarter, until AI chatbots ignited huge demand for computing power at the same time that conventional chips are hitting the limits of how much performance they can wring from every watt of power and are taxing electricity grids.
Nvidia's forthcoming "Rubin Ultra" AI data center server due in 2027, for example, is expected to consume about 600 kilowatts of power. That means operating that single server at full capacity for one hour would consume about two thirds the average power that a U.S. house uses in a month.
In that kind of changed world, dedicating a portion of a data center's power needs to cryogenic coolers makes sense if the performance gains are good enough, said Michael Lafferty, Snowcap's CEO, who formerly oversaw work on futuristic chips at Cadence Design Systems. Snowcap believes that even after accounting for energy used in cooling, its chips will be about 25 times better than today's best chips in terms of performance per watt.
"Power (efficiency) is nice, but performance sells," Lafferty said. "So we're pushing the performance level way up and pulling the power down at the same time."
Snowcap's founding team includes two scientists - Anna Herr and Quentin Herr - who have done extensive work on superconducting chips at chip industry research firm Imed and defense firm Northrop Grumman, as well as former chip executives from Nvidia and Alphabet's Google.
While the chips can be made in a standard factory, they will require an exotic metal called niobium titanium nitride that Lafferty said depends on Brazil and Canada for key ingredients. Snowcap plans its first basic chip by the end of 2026, but full systems will not come until later.
Despite the long development timeline, Pat Gelsinger, Intel's former CEO who led the investment for venture firm Playground Global and is joining Snowcap's board, said the computing industry needs a sharp break from its current trajectory of consuming ever more electricity.
"A lot of data centers today are just being limited by power availability," Gelsinger said.

Uber, Waymo launch autonomous ride-hailing service in Atlanta
Uber Technologies on Tuesday is beginning autonomous ride-hailing in Atlanta with Alphabet unit Waymo after offering the service in Austin, Texas, since March. The companies, which first announced the plan for the Atlanta service in September 2024, will offer Waymo autonomous vehicles on the Uber app for travel across 65 square miles (168 square km) of Atlanta. The race to deploy robotaxis is picking up pace as Waymo expands testing and Tesla began limited trials of its autonomous taxi service in Austin on Sunday, a sign of growing momentum in self-driving vehicles. There are now 100 Waymo vehicles on the Uber platform in Austin and it will launch with dozens in Atlanta. Uber will manage and dispatch a fleet of fully autonomous, all-electric Jaguar I-PACE vehicles that "will grow to hundreds" over time, the company said last year. Riders will pay the same rates as UberX, Uber Comfort, or Uber Comfort Electric when driven in a Waymo self-driving vehicle but they will not be prompted to tip. Waymo is operating fully autonomously on highways in California and Arizona for employees but not yet for the public. The Atlanta service is limited to surface streets. Last week, Waymo said its vehicles will be back in New York City next month for autonomous testing. Waymo has applied for a permit from the New York City Department of Transportation to operate autonomously, with a trained specialist behind the wheel in Manhattan. Waymo in March said it aims to launch fully autonomous ride-hailing in the U.S. capital city of Washington next year. Waymo has more than 1,500 vehicles running over 250,000 rides a week across San Francisco, Los Angeles, Phoenix and Austin. Uber sold its own self-driving division in 2020 to reduce cash burn and refocus on its core business, including ride hailing and food delivery after the 2018 death of a pedestrian who was struck by a self-driving Uber. The backup safety driver behind the wheel of the Uber in the fatal crash pleaded guilty in 2023 and was sentenced to probation, prosecutors said.

Dollar falls as Israel-Iran ceasefire triggers drop in oil prices
The U.S. dollar fell on Tuesday after President Donald Trump announced a ceasefire between Israel and Iran, in news that sparked a risk rally and a sharp drop in oil prices. Trump announced a complete ceasefire between Israel and Iran, potentially ending the 12-day conflict that led millions of people to flee Tehran and prompted fears of further escalation in the war-torn region. Israel has agreed to Trump's proposal, saying it has achieved its goal of removing Tehran's nuclear and ballistic missile threat. The yen and euro benefited from a sharp fall in oil prices as both the European Union and Japan rely heavily on imports of oil and liquefied natural gas, while the U.S. is a net exporter. Against the yen, the dollar was down 0.75 per cent at 145.03. The euro rose 0.27 per cent to $1.1609. It hit $1.1632 a couple of weeks ago, its highest level since October 2021. Adding to the pressure on the dollar were dovish comments from Federal Reserve policymaker Michelle Bowman, who said the U.S. central bank should consider interest rate cuts soon, triggering a fall in U.S. Treasury yields. Fed Governor Christopher Waller said in a television interview last week that he would consider a rate cut at next month's meeting as well. Mohit Kumar, economist at Jefferies, said he expected the Fed to take more time before easing. "We are not in the July camp, but do believe that data should show signs of weakness over the summer months and hence prompt a rate cut in September." Trump said on Tuesday that U.S. rates should be lowered by at least two to three percentage points. Markets are now pricing in close to a 23 per cent chance the Fed could ease rates in July, up from 14.5 per cent a day ago, according to the CME FedWatch tool. Against a basket of currencies, the dollar was down 0.14 per cent at 98.09, extending its more than 0.5 per cent decline in the previous session. Fed Chair Jerome Powell is due to testify before the U.S. Congress on Tuesday and Wednesday, where focus will be on the outlook for U.S. rates. The risk-sensitive Australian dollar got a lift and last traded 0.7 per cent higher at $0.6506 as did the New Zealand currency, which rose 0.75 per cent to $0.6025. Israel's shekel rallied sharply too, jumping 1.5 per cent against the dollar to its strongest level since February 2023. "It's obviously positive news for risk sentiment," said Rodrigo Catril, senior currency strategist at National Australia Bank, of the announced ceasefire. "We need to obviously have a bit more detail in terms of exactly what all this means ... I suppose it will be the conditions of the ceasefire, and what are the conditions for a longer-lasting peace deal." In cryptocurrencies, bitcoin rose 2 per cent to $105,832, while ether jumped 3.2 per cent to $2,425, in a reflection of the positive risk sentiment.

Recession-proof your wallet: 6 smart cuts to strengthen your finances in uncertain times
As speculations of economic ambiguity amplify, people are already trimming expenses, and the numbers prove it. From January through late March 2025, expenditure for clothing and accessories retailers fell by nearly 4% compared to 2024, with March alone plummeting 5.3%. Luxury fashion outlay for each household saw a 9% decrease last year, while footwear sales remained flat. In a nutshell, customers are silently turning from indulgence to saving. But an unstable economy doesn't have to mean a personal financial catastrophe. It's the ideal time to be deliberate about where your money goes. Cutting back isn't just about surviving a recession; it's about practising stronger financial behaviours that last. By reconsidering specific types of spending, you can improve your financial elasticity and lessen pressure, all while being equipped for whatever is coming. According to an article from New Trader U , here are six major consumption practices worth reevaluating when the economic prediction turns gloomy: New cars: A costly drive into depreciation – A new vehicle may be thrilling, but it promptly drops in value once you drive it off the lot. In difficult times, assuming a huge monthly expense for a depreciating asset can ruin your financial elasticity. Unless it's an actual requirement, consider sticking with your current automobile or try exploring the second-hand market instead. See also Park Shin Hye and Yoo Ah In's latest movie is a hit Luxury goods: Trade labels for liquidity – Expensive fashion and designer accessories may feel like status symbols, but they don't offer you the security of a vigorous investment or savings account or a lifestyle without debt. With luxury expenses already diminishing, this is one of the easiest areas to slash without losing the basics. High-interest debt: Avoid digging a deeper hole – Having credit card balances or taking on new high-interest loans during unpredictable times is like attempting to plunge into an ocean with chains around your ankles. With the standard credit card interest rates topping 22%, it's best to work on settling down remaining balances rather than getting into new ones. Bulk buys: When less is more – Normally, buying wholesale can save money, but it also puts away cash that can be used elsewhere. During difficult times, liquidity matters. Unless you're stockpiling purely for basic needs, don't jump on piling up your storage room with six months' worth of paper towels or food stuff. Tech upgrades: Stick with what works – Your laptop, smartphone, or tablet might not be the newest models, but if they still work, then hold onto them. Tech advancements are among the most optional overheads, and postponing them or ignoring them can keep hundreds in your wallet for more urgent matters and financial goals. Impulse buys: Deals that drain your budget – Clearance or midnight sales are intended to lure you into buying things you didn't plan to acquire. A deal is only a deal if it aligns with your needs and your financial capability. That '50% off' label doesn't matter if you never wanted the item in the first place. A stronger you, regardless of the economy Difficult times call for prudent decisions and wise choices. By making practical decisions now, you're not just responding to the economy or addressing your financial limbo; you're taking control of your future. Intelligent expenditures today mean greater freedom in the future. See also What to do when you feel super sleepy at work?
