4 health benefits of rosemary, including a hidden compound scientists could potentially use to fight Alzheimer’s

As you place sprigs of rosemary on a pan to roast alongside chicken or in a garlicky loaf of bread, you may not be thinking about the potential health properties this common herb is wielding.
It turns out, rosemary is a well-studied herb with myriad benefits—from boosting hair growth to potentially helping fight cancer.
Here’s how to take advantage of this natural health powerhouse.
Stimulate hair growth
While there are countless hair-growth supplements and hacks that circulate social media, rosemary oil, extracted from rosemary plants, is a tried-and-true tool to boost hair growth, backed by science.
In one study comparing the effectiveness of rosemary oil compared to minoxidil—a common medication used to stimulate hair growth in men and women—participants saw significant hair growth from both products after six months, with no difference between the two treatments’ effectiveness.
A comprehensive review of studies on the hair loss condition alopecia demonstrated that rosemary oil is an effective treatment due to its ability to improve scalp blood flow and enhance the regeneration of the hair follicles.
Improve skin health
Rosemary also has the potential to help heal the skin, according to a 2023 review of studies. Oxidative stress to the skin, caused by things like ultraviolet (UV) light, environmental pollution and chronic psychological stress, can damage the skin and lead to further skin aging and may play a role in skin cancer, according to researchers.
But thanks to its antioxidant and anti-inflammatory properties, rosemary could help treat some skin diseases either when ingested or applied to the skin.
Anticancer properties
Rosemary’s anticancer potential is more than skin deep: Ingesting rosemary was found to help stop the activation of carcinogens, increase antioxidant enzyme activities, reduce tumor-stimulating inflammation, decrease cell growth (which can lead to the production of cancerous cells), stimulate programmed cell death, and suppress tumor growth and invasion, according to a 2020 study.
Brain health and Alzheimer’s treatment
The benefits of rosemary extend to your nervous system, according to a 2020 review of studies. Rosemary extract showed anti-spasm, pain-relieving, anti-inflammatory, anti-anxiety and memory-boosting properties.
The study concluded that components of rosemary show promise in the treatment of anxiety, depression, Alzheimer’s disease, epilepsy, Parkinson’s disease, and withdrawal syndrome, researchers found.
For Alzheimer’s in particular, a January 2025 study in mice linked a compound found in rosemary to boosts in memory, more neuron synapses, reduced inflammation, and greater removal of toxic proteins that are linked to Alzheimer’s. It was administered to mice three times a week for three months, with no observable toxic effects.
How to use rosemary for your health
All of the studies on rosemary have limitations: The use different a dose as well as different methods of extracting and administering rosemary, making it difficult to put the findings into clinical practice. In the anticancer study, authors also raised concerns about chronic use of rosemary extract becoming toxic.
While the Food and Drug Administration designates rosemary extract as generally recognized as safe (GRaS), there is no recommended daily allowance. Talk to your doctor before taking any supplement to make sure it’s safe for you.
The most common forms of rosemary are the herb or as an essential oil. You should not ingest the essential oil as it is highly concentrated and can be toxic when ingested, according to Poison Control. If you want to apply it to your skin, they recommend diluting it with a carrier oil like jojoba or argan oil. Rosemary essential oil is generally safe when inhaled through an aroma diffuser.
To reap the benefits of rosemary, you can steep the herb in boiling water and drink it as a tea, or make it a regular part of your cooking.
Mount Sinai Hospital advises, however, that pregnant and nursing women avoid taking rosemary as a supplement, as higher doses can potentially cause miscarriage—but, it is still safe to consume as an herb in food. Additionally, people with high blood pressure, ulcers, Crohn’s disease, or ulcerative colitis should not take rosemary.

How news organizations should overhaul their operations as the gen AI threatens their livelihoods

Hello and welcome to Eye on AI. In this edition…The news media grapples with AI; Trump orders U.S. AI Safety efforts to refocus on combating ‘ideological bias’; distributed training is gaining increasing traction; increasingly powerful AI could tip the scales toward totalitarianism.
AI is potentially disruptive to many organizations’ business models. In few sectors, however, is the threat as seemingly existential as the news business. That happens to be the business I’m in, so I hope you will forgive a somewhat self-indulgent newsletter. But news ought to matter to all of us since a functioning free press performs an essential role in democracy—informing the public and helping to hold power to account. And, there are some similarities between how news executives are—and critically, are not—addressing the challenges and opportunities AI presents that business leaders in other sectors can learn from, too.
Last week, I spent a day at an Aspen Institute conference entitled “AI & News: Charting the Course,” that was hosted at Reuters’ headquarters in London. The conference was attended by top executives from a number of U.K. and European news organizations. It was held under Chatham House Rules so I can’t tell you who exactly said what, but I can relay what was said.
Tools for journalists and editors
News executives spoke about using AI primarily in internally-facing products to make their teams more efficient. AI is helping write search engine-optimized headlines and translate content—potentially letting organizations reach new audiences in places they haven’t traditionally served, though most emphasized keeping humans in the loop to monitor accuracy.
One editor described using AI to automatically produce short articles from press releases, freeing journalists for more original reporting, while maintaining human editors for quality control. Journalists are also using AI to summarize documents and analyze large datasets—like government document dumps and satellite imagery—enabling investigative journalism that would be difficult without these tools. These are good use cases, but they result in modest impact—mostly around making existing workflows more efficient.
Bottom-up or top-down?
There was active debate among the newsroom leaders and techies present about whether news organizations should take a bottom-up approach—putting generative AI tools in the hands of every journalist and editor, allowing these folks to run their own data analysis or “vibe code” AI-powered widgets to help them in their jobs, or whether efforts should be top-down, with the management prioritizing projects.
The bottom-up approach has merits—it democratizes access to AI, empowers frontline employees who often know the pain points and can often spot good use cases before high-level execs can, and frees limited AI developer talent to be spent only on projects that are bigger, more complex, and potentially more strategically important.
The downside of the bottom-up approach is that it can be chaotic, making it hard for the organization to ensure compliance with ethical and legal policies. It can create technical debt, with tools being built on the fly that can’t be easily maintained or updated. One editor worried about creating a two-tiered newsroom, with some editors embracing the new tech, and others falling behind. Bottom-up also doesn’t ensure that solutions generate the best return on investment—a key consideration as AI models can quickly get expensive. Many called for a balanced approach, though there was no consensus on how to achieve it. From conversations I’ve had with execs in other sectors, this dilemma is familiar across industries.
Caution about jeopardizing trust
News outfits are also being cautious about building audience-facing AI tools. Many have begun using AI to produce bullet-point summaries of articles that can help busy and increasingly impatient readers. Some have built AI chatbots that can answer questions about a particular, narrow subset of their coverage—like stories about the Olympics or climate change—but they have tended to label these as “experiments” in order to help flag to readers that the answers may not always be accurate. Few have gone further in terms of AI-generated content. They worry that gen AI-produced hallucinations will undercut trust in the accuracy of their journalism. Their brands and their businesses ultimately depend on that trust.
Those who hesitate will be lost?
This caution, while understandable, is itself a colossal risk. If news organizations themselves aren’t using AI to summarize the news and make it more interactive, technology companies are. People are increasingly turning to AI search engines and chatbots, including Perplexity, OpenAI’s ChatGPT, and Google’s Gemini and the “AI Overviews” Google now provides in response to many searches, and many others. Several news executives at the conference said “disintermediation”—the loss of a direct connection with their audience—was their biggest fear.
They have cause to be worried. Many news organizations (including Fortune) are at least partly dependent on Google search to bring in audiences. A recent study by Tollbit—which sells software that helps protect websites from web crawlers—found that clickthrough rates for Google AI Overviews were 91% lower than from a traditional Google Search. (Google has not yet used AI overviews for news queries, although many think it is only a matter of time.) Other studies of click through rates from chatbot conversations are equally abysmal. Cloudflare, which is also offering to help protect news publishers from web scraping, found that OpenAI scraped a news site 250 times for every one referral page view it sent that site.
So far, news organizations have responded to this potentially existential threat through a mix of legal pushback—the New York Times has sued OpenAI for copyright violations, while Dow Jones and the New York Post have sued Perplexity—and partnerships. Those partnerships have involved multiyear, seven-figure licensing deals for news content. (Fortune has a partnership with both Perplexity and ProRata.) Many of the execs at the conference said the licensing deals were a way to make revenue from content the tech companies had most likely already “stolen” anyway. They also saw the partnerships as a way to build relationships with the tech companies and tap their expertise to help them build AI products or train their staffs. None saw the relationships as particularly stable. They were all aware of the risk of becoming overly reliant on AI licensing revenue, having been burned previously when the media industry let Facebook become a major driver of traffic and ad revenue. Later, that money vanished practically overnight when Meta CEO Mark Zuckerberg decided, after the 2016 U.S. presidential election, to de-emphasize news in people’s feeds.
An AI-powered Ferrari yoked to a horse cart
Executives acknowledged needing to build direct audience relationships that can’t be disintermediated by AI companies, but few had clear strategies for doing so. One expert at the conference said bluntly that “the news industry is not taking AI seriously,” focusing on “incremental adaptation rather than structural transformation.” He likened current approaches to a three-step process that had “an AI-powered Ferrari” at both ends, but “a horse and cart in the middle.”
He and another media industry advisor urged news organizations to get away from organizing their approach to news around “articles,” and instead think about ways in which source material (public data, interview transcripts, documents obtained from sources, raw video footage, audio recordings, and archival news stories) could be turned into a variety of outputs—podcasts, short form video, bullet-point summaries, or yes, a traditional news article—to suit audience tastes on the fly by generative AI technology. They also urged news organizations to stop thinking of the production of news as a linear process, and begin thinking about it more as a circular loop, perhaps one in which there was no human in the middle.
One person at the conference said that news organizations needed to become less insular and look more closely at insights and lessons from other industries and how they were adapting to AI. Others said that it might require startups—perhaps incubated by the news organizations themselves—to pioneer new business models for the AI age.
The stakes couldn’t be higher. While AI poses existential challenges to traditional journalism, it also offers unprecedented opportunities to expand reach and potentially reconnect with audiences who have “turned off news”—if leaders are bold enough to reimagine what news can be in the AI era.
With that, here’s more AI news.

How to watch the First Four of the 2025 NCAA Tournament for free—and without cable

- The First Four games of the NCAA Tournament are being held Tuesday and Wednesday, March 18 and 19. They’re an appetizer, of sorts, for the first round of March Madness, one of the most anticipated basketball tournaments of the year.
Selection Sunday is behind us. Now it’s time for March Madness to get underway. (Sorry, HR directors!)
The NCAA Tournament is one of the highlights of spring and while the Round of 64 will get underway later this week, fans will get an appetizer starting tonight with the First Four games.
This matchup sees the four lowest-seeded automatic qualifiers and the four lowest-seeded at-large teams face off in an attempt to make it to the official tournament. It’s where Cinderella stories are born and where longshot bets can pay off (though rarely do).
Here’s a look at who’s playing in the First Four—and some options to watch them.

Cathie Wood says most memecoins will end up ‘worthless’

Most of the so-called memecoins that are flooding the $2.6 trillion cryptocurrency space will probably end up “worthless,” according to Cathie Wood.
The combination of blockchain technology and artificial intelligence is creating “millions” of meme cryptocurrencies that “are not going to be worth very much,” the ARK Investment Managment LLC founder and CEO told Bloomberg Television on Tuesday, adding that her private funds are not putting money into these coins.
Memecoins are a type of digital asset often inspired by jokes, current events or trends in popular culture. In February, the US Securities and Exchange Commission said memecoins are not considered securities so they will remain unregulated.
“If I have one message for those listening who are buying memecoins: buyer beware,” said Wood. “There’s nothing like losing money for people to learn, and they’ll learn that the SEC and regulators are not taking responsibility for these memecoins.”
