Rice University's OpenStax is able to greatly expand its library of free online textbooks thanks to new grants totaling $12.5 million. The funds derive from Bill & Melinda Gates Foundation, the William and Flora Hewlett Foundation, the Charles Koch Foundation and the Stand Together community, according to a press release from Rice.

The new funds will more than double OpenStax's files from 42 books to 90. Already, the platform has saved 14 million students around the world more than $1 billion.

"Nine years ago, we dreamed about solving the textbook affordability and access crisis for students," says Richard Baraniuk, the Victor E. Cameron Professor of Electrical and Computer Engineering at Rice and founder and director of OpenStax, in the release. "Now, with this tremendous investment in open education, we will be able to not only accelerate educational access for tens of millions of students but also drive innovation in high-quality digital learning, which has become commonplace due to COVID-19."

OpenStax is planning to raise $30 million for continued library expansion as it aims to lower the barrier to higher education.

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.

Houston startup debuts bio-based 'leather' fashion collection in Milan

sustainable fashion

Earlier this month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.
