The U.S. National Science Foundation National Quantum Virtual Laboratory (NSF NQVL) is coming into sharper focus with the selection of the first four teams that will design high-tech infrastructure to be broadly used across the country. NSF is investing $16 million in the four teams, with each receiving $4 million over two years. The NSF NQVL initiative is an ambitious effort to accelerate the development of useful quantum technologies by providing researchers anywhere in the U.S. with access to specialized resources.

The teams selected by NSF will design practical ways to expand access to the hardware and software needed for quantum science, engineering and technology development, which are currently highly bespoke and concentrated in relatively few labs. Among the design projects are plans to create shareable, networked quantum computers that can be used for experimentation from any location and a “digital twin” (a dynamic simulation that changes and responds to inputs) of a quantum computer that can be used by any U.S. researcher to test and refine new quantum algorithms.

“The National Quantum Virtual Laboratory is a critical bridge between basic discovery and deployment, specifically focused on turning America’s leadership in fundamental quantum science into practical technologies, products, and systems that will strengthen our nation’s competitiveness and ensure U.S. dominance in this field for decades to come,” said Brian Stone, performing the duties of

In-brief analysis

September 4, 2025

U.S. imports of biodiesel and renewable diesel significantly decreased in the first half of 2025 (1H25) compared with the same period in previous years. This decline is primarily due to the loss of tax credits for imported biofuels and generally lower domestic consumption of these fuels.

Renewable diesel and biodiesel are biomass-based diesel fuels that can replace petroleum-based distillate and be used to comply with the Renewable Fuel Standard (RFS) blending requirements for refiners administered by the U.S. Environmental Protection Agency.

In 1H25, U.S. biodiesel imports averaged 2,000 barrels per day (b/d), a sharp drop from 35,000 b/d in 1H24. Renewable diesel imports averaged 5,000 b/d, down from 33,000 b/d in 1H24. These import levels were the lowest for the first half of any year since 2012, when U.S. biodiesel consumption was

During Black Friday in 2024, Stripe processed more than $31 billion in transactions, with processing rates peaking at 137,000 transactions per minute, the highest in the company’s history. The financial-services firm had to analyze every transaction in real time to prevent nearly 21 million fraud attempts that could have siphoned more than $910 million from its merchant customers. 

Yet, fraud protection is only one reason that Stripe embraced real-time data analytics. Evaluating trends in massive data flows is essential for the company’s services, such as allowing businesses to bill based on usage and monitor orders and inventory. In fact, many of Stripe’s services would not be possible without real-time analytics, says Avinash Bhat, head of data infrastructure at Stripe. “We have certain products that require real-time analytics, like usage-based billing and fraud detection,” he says. “Without our real-time analytics, we would not have a few
