New research suggests dusty leaves can feed plants in nutrient-poor ecosystems.New findings suggest cell size could sharpen cancer prognosis.The race to field China's first reusable launch vehicle is far less predictable than a similar competition that played out in the United States a decade ago.
There was never any real question of which company would develop and demonstrate the first reusable orbital-class rocket in the United States. SpaceX landed a Falcon 9 booster for the first time in 2015, and a little more than a year later, it launched it back into space. It took nearly 10 years for anyone else to do the same. Blue Origin celebrated its first orbital-class booster landing last November with the successful recovery of one of its New Glenn boosters, followed by a relaunch of the same rocket in April.
In China, several companies and state-owned enterprises have a realistic shot at landing an orbital-class booster stage this year. For a time, it seemed like China's new crop of privately funded launch companies might have the advantage in accomplishing the first landing of an orbital-class booster. But Monday's launch of China's Long March 12B rocket, backed by the nearly unrestricted resources of the country's vast state-owned aerospace enterprise, suggests the industry's legacy players may now have a leg up.

It’s hard for people to tell the difference between AI-generated advertising and writing. So why do they respond better to the human-made stuff?
Ipsos, along with faculty members from Syracuse University’s S.I. Newhouse School of Public Communications, just published a unique advertising study. They took 20 real ads from major brands, including Cheerios, Chewy, Febreze, Fiat, H&M, Old Navy, Herbal Essences, Ray-Ban Meta, TurboTax and Visa. They fed the same creative briefs used by the human ad creatives into Google Gemini, then used OpenAI’s Sora to generate fully AI-produced counterparts with no human intervention.
They showed the ads to 3,000 consumers. Only 25% of AI ad viewers were at least somewhat confident the spot was AI-made, and 40% of all viewers were uncertain either way — suggesting the public isn’t great at spotting ads that are AI generated.
But here’s the interesting part: While most people didn’t register that ads were AI-generated, they also didn’t respond to them like they did with human-generated ads. They consistently rated human-made work as more eye-catching and more imaginative.
In other words, people assumed AI ads were made by people, but didn’t particularly like them compared to human-generated ads. And that means human-generated ads performed much better.
Ads made by people without AI were 14% stronger on short-term sales impact and 17% stronger on long-term brand health.
To me, the data here suggests that while people can’t easily discern the difference between AI- and human-generated content, the AI stuff hits wrong on a subconscious level. And I think that’s happening with AI social posts, AI blog posts and AI slop in general.
In fact, I’ve noticed it strongly in my own response to AI-generated content. It often looks perfect but bothers me for reasons that aren’t immediately obvious.
The researchers explained AI’s inability to match human ad creativity by pointing out that AI draws from what already exists, while great advertising breaks new ground. AI can replicate the conventions of advertising, but it can’t transcend them, make a creative leap or engender emotion like people can.
A broad range of research beyond the Ipsos study suggests that skillful people working with AI tools will always outperform AI alone, and often outperform people not using AI tools. Ipsos’ advice? Ad agencies should keep people at the center of brand storytelling and emotive assets.
Another recent study looked at written web content and compared how human-written articles “performed” on search engines compared to AI-generated content. Semrush analyzed 42,000 blog pages across 20,000 keywords, ran every single one through GPTZero’s AI detector, and cross-referenced the results with actual Google Search results. It also surveyed 224 search-engine optimization (SEO) professionals about their AI habits and beliefs.
They found a disconcerting disconnect between what SEO people believe and what is actually true. Some 72% of SEO professionals who use AI content say it performs just as well or better than human-written content in search rankings. But it turns out that human-generated posts strongly outperform AI-generated.
Content classified as purely AI-generated appeared in the top spot in search result just 9% of the time. Content classified as human-written was there 80% of the time.” That’s a roughly 8-to-1 advantage. (Note that the coveted top link in search results typically gets around one-third of the clicks.)
For lower page-one positions — from the fifth position down (which get relatively few clicks) — AI- and human-generated posts perform more similarly. (The researchers also found that when people write posts with a little help from AI, their posts rank better much than AI-only content.)
Those Semrush results are consistent with previous research.
Note that engagement performance varied by industry; that 61% result is an aggregate average across all industries. Ironically, in the category of “Leadership & Inspiration,” AI posts outperformed human posts by 75%.
The absurd lesson here: If you want to be a thought leader on LinkedIn, don’t lead with your own thoughts.
What all this research boils down to is that human-generated content (with or without help from AI) attracts far more traffic and higher engagement than AI-generated content. AI content is essentially invisible in high-value channels and while it might be high in quantity, it’s low in quality where it really matters — with reach and influence.
As with the ad creative study by Ipsos, the conclusion of all this research is the same: People (and search engines) respond much better to creative content produced by people compared with AI-generated content.
In short, AI is great at “flooding the zone” at high speed and low cost — and there’s a ton of AI-generated content out there. A quick check reveals that:
The specific numbers are my best estimates, and they’re changing fast each month. The takeaway is that AI-generated content is exploding in volume.
But it isn’t reaching people the way human-generated content does. Take podcasts, for example. While roughly 40% of new podcast episode uploads are AI-generated, that 40% captures less than 1% of the listening hours. Of the top 100 podcasts, zero are AI-generated.
A clear picture is emerging about the use of AI for content generation. AI is great for churning out a lot of content at low cost. It can be good for some kinds of content — if a skillful person directs it. And AI can be a helpful tool for content creators.
But when it comes to direct comparisons between people and AI, it’s clear that the winning content — the stuff with the best “performance” on search, best reception by people and the most engaging — is always human-generated.
Welcome to Edition 8.43 of the Rocket Report! A disclaimer: No one yet fully appreciates the ramifications of Blue Origin's New Glenn rocket explosion Thursday night on its launch pad at Cape Canaveral, Florida. What we know as of this writing is that much of Blue's sole orbital-class launch pad has been destroyed, and the New Glenn rocket will be grounded for an extended period of time. It is too soon for any hot takes, at least until the Sun rises at the Cape on Friday morning. One thing I am sure of is that we will be writing about this event for weeks, months, and years to come.
As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.
Charting China's contribution to space junk. There's a problem with the drastic uptick in Chinese space launches over the last decade. China appears to be ignoring long-established norms about disposing of the upper stages of rockets, Ars reports. These are the parts of the vehicle that separate from the first stage of a rocket and push a satellite or spacecraft into orbit. In the early decades of spaceflight, launch operators routinely left upper stages in orbit after they released their payloads. But most launch companies today reserve enough propellant in their rockets to remove them from orbit to avoid the risk of spent upper stages becoming a source of space debris. But China is not following this trend. There has been striking growth in China’s rocket body mass. In the past five years, the mass of Chinese rocket bodies in long-lived orbits has risen from less than 100 metric tons to 252, according to a new analysis by Space Domain Awareness expert Jim Shell.
