In a rare moment of solidarity, two entertainment giants are teaming up to try to get consumers to stop canceling their streaming services so frequently.

Disney and Warner Bros. Discovery announced on Wednesday that they would start offering a bundle of their Disney+, Hulu and Max streaming services this summer, a sign of how rivals have become more willing to join forces in order to confront an ever-changing media landscape.

The companies said that the bundle would be available to buy on any of the three streaming platform’s websites (Disney owns Disney+ and Hulu; Warner Bros. Discovery owns Max), and that there would be a commercial-free version as well as one featuring ads. The companies did not announce prices or a date when the offering would become available.

The monthly retail price for subscribing to commercial-free versions of all three services is currently $48; the plans with ads cost a combined $25. A bundled offering is likely to cost less.

Media executives have been vexed in recent years as the extremely profitable cable bundle has come undone by cord cutting, and as viewers have rapidly turned to on-demand streaming entertainment. The transition to streaming has been difficult for the companies, which have been bleeding cash.

Disney, for instance, announced this week that Disney+ was profitable last quarter for the first time, though its overall streaming division lost money.

Adding to the uncertainty, consumers have shown a much greater willingness to cull and cut streaming services over the last year or so, further confounding executives who have slashed costs and reduced the number of television shows to get closer to making meaningful profits.

Disney has introduced a bundle for Disney+, Hulu and ESPN+. The company has said it has seen good results from that offering.

Executives have been flirting with the idea of cobbling together a streaming offering across media companies to give consumers less incentive to cancel. The Disney+, Hulu and Max offering is a significant step in that direction.

Joe Earley, the president of Disney Entertainment’s direct-to-consumer division, said in a statement that the “new partnership puts subscribers first.” JB Perrette, the chief executive of Warner Bros. Discovery’s global streaming unit, called it “a powerful new road map for the future of the industry.”

In February, Disney, Warner Bros. Discovery and Fox said they were forming a joint venture to create a streaming service dedicated to their sports offerings. It is expected to debut in the fall.

Artificial intelligence is giving machines the power to generate videos, write computer code and even carry on a conversation.

It is also accelerating efforts to understand the human body and fight disease.

On Wednesday, Google DeepMind, the tech giant’s central artificial intelligence lab, and Isomorphic Labs, a sister company, unveiled a more powerful version of AlphaFold, an artificial intelligence technology that helps scientists understand the behavior of the microscopic mechanisms that drive the cells in the human body.

An early version of AlphaFold, released in 2020, solved a puzzle that had bedeviled scientists for more than 50 years. It was called “the protein folding problem.”

Proteins are the microscopic molecules that drive the behavior of all living things. These molecules begin as strings of chemical compounds before twisting and folding into three-dimensional shapes that define how they interact with other microscopic mechanisms in the body.

Biologists spent years or even decades trying to pinpoint the shape of individual proteins. Then AlphaFold came along. When a scientist fed this technology a string of amino acids that make up a protein, it could predict the three-dimensional shape within minutes.

When DeepMind publicly released AlphaFold a year later, biologists began using it to accelerate drug discovery. Researchers at the University of California, San Francisco, used the technology as they worked to understand the coronavirus and prepare for similar pandemics. Others used it as they struggled to find remedies for malaria and Parkinson’s disease.

The hope is that this kind of technology will significantly streamline the creation of new drugs and vaccines.

“It tells us a lot more about how the machines of the cell interact,” said John Jumper, a Google DeepMind researcher. “It tells us how this should work and what happens when we get sick.”

The new version of AlphaFold — AlphaFold3 — extends the technology beyond protein folding. In addition to predicting the shapes of proteins, it can predict the behavior of other microscopic biological mechanisms, including DNA, where the body stores genetic information, and RNA, which transfers information from DNA to proteins.

“Biology is a dynamic system. You need to understand the interactions between different molecules and structures,” said Demis Hassabis, Google DeepMind’s chief executive and the founder of Isomorphic Labs, which Google also owns. “This is a step in that direction.”

The company is offering a website where scientists can use AlphaFold3. Other labs, most notably one at the University of Washington, offer similar technology. In a paper released on Tuesday in the scientific journal Nature, Dr. Jumper and his fellow researchers show that it achieves a level of accuracy well beyond the state of the art.

The technology could “save months of experimental work and enable research that was previously impossible,” said Deniz Kavi, a co-founder and the chief executive of Tamarind Bio, a start-up that builds technology for accelerating drug discovery. “This represents tremendous promise.”
