DISCOVERY OF CELLS THAT KEEP IMMUNE RESPONSES IN CHECK WINS MEDICINE NOBEL PRIZE

Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi were awarded the 2025 Nobel Prize in Physiology or Medicine for their work in the discovery of specialized immune cells that keep potentially harmful immune responses in check. These regulatory T cells play a key role in peripheral immune tolerance, a non-central process that allows the immune system to balance its response. The discovery has opened up new lines of research into peripheral immune tolerance. Researchers are now working on manipulating T cells so that they can't protect cancerous tumors, engineering them to treat autoimmune diseases, and recruiting them to protect transplanted organs and tissues.

US V. GOOGLE: WHAT EACH SIDE ARGUED FOR FIXING GOOGLE'S AD TECH MONOPOLY

The Justice Department and Google spent two weeks arguing over how to address Google's illegal monopoly in advertising software. The government argued that the only way to end Google's dominance in ad tech is to force a breakup and make Google sell the software that connects the buyers and sellers of ad space. Google says that the proposal was too complicated to pull off without harming publishers and instead proposed that the company make its systems work better with products produced by its competitors. The judge presiding over the case will reach a decision in the coming months.

APPLE PUTS HARDWARE CHIEF JOHN TERNUS IN THE SUCCESSION SPOTLIGHT

Several of Apple's executives are expected to relinquish their responsibilities in the near future - some of them were once seen as Tim Cook's heir, making the future of the company uncertain. The company needs to urgently beef up its AI business, which could mean a shake-up or even an acquisition. Big changes are likely, especially as some executives don't have obvious successors. Cook will likely remain involved with Apple in some capacity when he eventually steps down as CEO, perhaps as a board chairman. John Ternus remains the leading contender as Cook's successor.

OPENAI'S INVITE-ONLY VIDEO GENERATION APP SORA TOPS APPLE'S APP STORE

OpenAI's new video generation app, Sora, has snagged the No. 1 spot on Apple's App Store. The app allows users to generate short-form AI videos, remix videos created by other users, and post them to a shared feed. It is only available on iOS and is invite-based. The app gives users explicit control over how their likeness is used on the platform, but some videos have sparked debate about its utility, potential for harm, and legality.

THE FIGHT TO FIX PROSTATE CANCER CARE

Prostate cancer is the most common nonskin cancer among American men. Diagnostics and therapies for the disease generated about $12 billion to $15 billion worldwide last year.

SCALING ENGINEERING TEAMS: LESSONS FROM GOOGLE, FACEBOOK, AND NETFLIX

Scaling engineering teams is like raising teenagers. They grow fast, develop personalities of their own, and they need boundaries. Teams that thrive at scale tend to have structured goal-setting, a ruthless focus on code quality, and intentional culture building. This post shares lessons learned from scaling teams at Google, Facebook, and Netflix. It provides a few frameworks, metrics, and tools to help you scale to over a thousand engineers without losing your mind or your best people.

THE SELF-TAUGHT ENGINEER GOING HEAD-TO-HEAD WITH ELON MUSK AND JEFF BEZOS

Rocket Lab aims to fly its Neutron rocket, which is reusable, by the end of the year. Landing the rocket's booster will be a challenge - only SpaceX has achieved this feat. Rocket Lab's founder, Peter Beck, has a fixation on detail and form that has guided his course as an entrepreneur. The company's newly constructed launchpad is an example of this - it needed to be able to withstand 1.5 million pounds of thrust, but Beck added another requirement: it also had to look beautiful.

BLUE ORIGIN AIMS TO LAND NEXT NEW GLENN BOOSTER, THEN REUSE IT FOR MOON MISSION

The second launch of Blue Origin's New Glenn rocket will send two NASA-funded satellites toward Mars to study the processes that drove the planet's evolution from a warmer, wetter world to the cold, dry planet of today. A successful launch would nudge Blue Origin closer to winning certification from the Space Force to begin launching national security satellites. The company plans to recover the New Glenn rocket's first stage booster during the mission.

OPENAI'S SORA SOARS TO NO. 3 ON THE US APP STORE

OpenAI's Sora app saw 56,000 downloads on its first day. It is now ranked third Top Overall app on the US App Store, despite being invite-only and limited to users in the US and Canada. The ChatGPT app and Google's Gemini iOS apps had stronger launches, with each reaching at least 80,000 downloads on day one, but since Sora is invite-only, that may not be a fair comparison. The strong release indicates there is a demand for AI video tools with a social networking-like experience.

THE QUEST TO SEQUENCE THE GENOMES OF EVERYTHING

The Earth BioGenome Project (EBP) aims to obtain a genome sequence for every named species of eukaryotic organism on the planet by 2035. Its success will depend on researchers' ability to scale several biotech technologies. Specialists on the front lines of the genomic revolution in biology are confident that such scaling will be possible. Having a genome sequence for every eukaryotic creature will give researchers insights into how evolution proceeded for a myriad of life forms. It could lead to the discovery and development of many drugs, enzymes, catalysts, and other chemicals of incalculable value.
