Amazon has a new plan for its home robot Astro: to guard your life
The news: Amazon announced yesterday that its home robot, Astro, will be getting a slew of major updates aimed at further embedding it in homes—and in our daily lives.
The details: The new features offer more home monitoring. Astro will be able to watch pets and send a video feed of their activities to users, for example. But the robot will also be able to wander around the house to keep an eye on rooms and entry points. Amazon also announced a new collaboration between Astro and the Ring home security camera system designed to protect areas outside the home from possible break-ins.
Why it matters: Ring’s approach to surveillance hasn’t been without controversy. It’s reasonable to ask whether combining Astro’s ability to roam around a house with Ring’s established surveillance system might create even more problems than either product did in their previous iterations.

The pandemic created a “perfect storm” for Black women at risk of domestic violence
Starr Davis was smitten when she met a handsome stranger with flawless skin and a wide smile in March 2020. He was charming and persistent; but their whirlwind romance took a major turn when she fell pregnant. His aggressive behavior started to make her uncomfortable, but he was the father of her child.
He became physically abusive a few weeks after she moved in with him. He forbade her from setting foot outside, saying it was to protect her and their unborn child from covid. With no friends or close family nearby for support, she suffered in silence.
Covid seems to have made things worse for many women experiencing violence at home. Anti-domestic-violence advocates point to dramatic increases in calls to shelters and support groups, and many care workers say this increase in domestic violence seems to have disproportionately affected Black women like Davis.

The big story
Why the balance of power in tech is shifting toward workers
Something has changed for tech giants. Even as they continue to hold tremendous influence in our daily lives, a growing accountability movement has begun to check their power. Led in large part by tech workers themselves, a movement seeking reform of how these companies do business has taken on unprecedented momentum, particularly in the past year.
Concerns and anger over tech companies’ impact in the world is nothing new, of course. What’s changed is that workers are increasingly getting organized. Read the full story.

The Download: circumventing China’s firewall, and using AI to invent new drugs
As protests against rigid covid control measures in China engulfed social media in the past week, one Twitter account has emerged as the central source of information: @李老师不是你老师 (“Teacher Li Is Not Your Teacher”).
People everywhere in China have sent protest footage and real-time updates to the account through private messages, and it has posted them, with the sender’s identity hidden, on their behalf.
The man behind the account, Li, is a Chinese painter based in Italy, who requested to be identified only by his last name in light of the security risks. He’s been tirelessly posting footage around the clock to help people within China get information, and also to inform the wider world.
The work has been taking its toll—he’s received death threats, and police have visited his family back in China. But it also comes with a sense of liberation, Li told Zeyi Yang, our China reporter. Read the full story.
Biotech labs are using AI inspired by DALL-E to invent new drugs
The news: Text-to-image AI models like OpenAI’s DALL-E 2—programs trained to generate pictures of almost anything you ask for—have sent ripples through the creative industries. Now, two biotech labs are using this type of generative AI, known as a diffusion model, to conjure up designs for new types of protein never seen in nature.
Why it matters: Proteins are the fundamental building blocks of living systems. These protein generators can be directed to produce designs for proteins with specific properties, such as shape or size or function. In effect, this makes it possible to come up with new proteins to do particular jobs on demand. Researchers hope that this will eventually lead to the development of new and more effective drugs.

Methodology: The Blue Technology Barometer 2022/23
Now in its second year, the Blue Technology Barometer assesses and ranks how each of the world’s largest
maritime economies promotes and develops blue (marine-centered) technologies that help reverse the impact of
climate change on ocean ecosystems, and how they leverage ocean-based resources to reduce greenhouse gases and
other effects of climate change.
To build the index, MIT Technology Review Insights compiled 20 quantitative and qualitative data indicators
for 66 countries and territories with coastlines and maritime economies. This included analysis of select
datasets and primary research interviews with global blue technology innovators, policymakers, and
international ocean sustainability organizations. Through trend analysis, research, and a consultative
peer-review process with several subject matter experts, weighting assumptions were assigned to determine the
relative importance of each indicator’s influence on a country’s blue technology leadership.
These indicators measure how each country or territory’s economic and maritime industries have affected its
marine environment and how quickly they have developed and deployed technologies that help improve ocean
health outcomes. Policy and regulatory adherence factors were considered, particularly the observance of
international treaties on fishing and marine protection laws.
The indicators are organized into four pillars, which evaluate metrics around a sustainability theme. Each
indicator is scored from 1 to 10 (10 being the best performance) and is weighted for its contribution to its
respective pillar. Each pillar is weighted to determine its importance in the overall score. As these research
efforts center on countries developing blue technology to promote ocean health, the technology pillar is
ranked highest, at 50% of the overall score.
The four pillars of the Blue Technology Barometer are:
Carbon emissions resulting from maritime activities and their relative growth. Metrics in this pillar also
assess each country’s efforts to mitigate ocean pollution and enhance ocean ecosystem health.
Efforts to promote sustainable fishing activities and increase and maintain marine protected areas.
Progress in fostering the development of sustainable ocean technologies across several relevant fields:
- Clean innovation scores from MIT Technology Review Insights’ Green Future Index 2022.
- A tally of maritime-relevant patents and technology startups.
- An assessment of each economy’s use of technologies and tech-enabled processes that facilitate ocean

Your microbiome ages as you do—and that’s a problem
These ecosystems appear to change as we age—and these changes can potentially put us at increased risk of age-related diseases. So how can we best look after them as we get old? And could an A-grade ecosystem help fend off diseases and help us lead longer, healthier lives?
It’s a question I’ve been pondering this week, partly because I know a few people who have been put on antibiotics for winter infections. These drugs—lifesaving though they can be—can cause mass destruction of gut microbes, wiping out the good along with the bad. How might people who take them best restore a healthy ecosystem afterwards?
I also came across a recent study in which scientists looked at thousands of samples of people’s gut microbe populations to see how they change with age. The standard approach to working out what microbes are living in a person’s gut is to look at feces. The idea is that when we have a bowel movement, we shed plenty of gut bacteria. Scientists can find out which species and strains of bacteria are present to get an estimate of what’s in your intestines.
In this study, a team based at University College Cork in Ireland analyzed data that had already been collected from 21,000 samples of human feces. These had come from people all over the world, including Europe, North and South America, Asia, and Africa. Nineteen nationalities were represented. The samples were all from adults between 18 and 100.
The authors of this study wanted to get a better handle on what makes for a “good” microbiome, especially as we get older. It has been difficult for microbiologists to work this out. We do know that some bacteria can produce compounds that are good for our guts. Some seem to aid digestion, for example, while others lower inflammation.
But when it comes to the ecosystem as a whole, things get more complicated. At the moment, the accepted wisdom is that variety seems to be a good thing—the more microbial diversity, the better. Some scientists believe that unique microbiomes also have benefits, and that a collection of microbes that differs from the norm can keep you healthy.
The team looked at how the microbiomes of younger people compared with those of older people, and how they appeared to change with age. The scientists also looked at how the microbial ecosystems varied with signs of unhealthy aging, such as cognitive decline, frailty, and inflammation.
They found that the microbiome does seem to change with age, and that, on the whole, the ecosystems in our guts do tend to become more unique—it looks as though we lose aspects of a general “core” microbiome and stray toward a more individual one.
But this isn’t necessarily a good thing. In fact, this uniqueness seems to be linked to unhealthy aging and the development of those age-related symptoms listed above, which we’d all rather stave off for as long as possible. And measuring diversity alone doesn’t tell us much about whether the bugs in our guts are helpful or not in this regard.
The findings back up what these researchers and others have seen before, challenging the notion that uniqueness is a good thing. Another team has come up with a good analogy, which is known as the Anna Karenina principle of the microbiome: “All happy microbiomes look alike; each unhappy microbiome is unhappy in its own way.”
Of course, the big question is: What can we do to maintain a happy microbiome? And will it actually help us stave off age-related diseases?
There’s plenty of evidence to suggest that, on the whole, a diet with plenty of fruit, vegetables, and fiber is good for the gut. A couple of years ago, researchers found that after 12 months on a Mediterranean diet—one rich in olive oil, nuts, legumes, and fish, as well as fruit and veg—older people saw changes in their microbiomes that might benefit their health. These changes have been linked to a lowered risk of developing frailty and cognitive decline.
But at the individual level, we can’t really be sure of the impact that changes to our diets will have. Probiotics are a good example; you can chug down millions of microbes, but that doesn’t mean that they’ll survive the journey to your gut. Even if they do get there, we don’t know if they’ll be able to form niches in the existing ecosystem, or if they might cause some kind of unwelcome disruption. Some microbial ecosystems might respond really well to fermented foods like sauerkraut and kimchi, while others might not.
I personally love kimchi and sauerkraut. If they do turn out to support my microbiome in a way that protects me against age-related diseases, then that’s just the icing on the less-microbiome-friendly cake.
