In March 2025, Albuquerque launched a microtransit pilot deploying electric vans to connect food desert neighborhoods like South Valley to grocery stores, addressing a longstanding planning challenge. Funded by a $2 million USDOT grant, the program now serves around 1,500 residents weekly. Riders use a city-backed app to hail real-time rides, cutting travel times by 30 percent for low-income families, according to city data.

Unlike fixed-route buses, these agile vans can navigate narrow streets and reach underserved areas faster, making the program a replicable model for equitable transit. Planners cite the initiative as a direct intervention in zoning-induced food deserts, where 23 percent of Bernalillo County residents lack grocery access (USDA, 2025). However, questions remain about the program’s scalability due to maintenance costs.

The story offers a timely example of how small cities can use mobility innovation to promote food justice and reimagine last-mile transit.

Bacteria operate by a pretty simple set of biological commands: survive and reproduce. But a recent study is highlighting that, in some cases, the microscopic organisms will follow those commands by any means necessary. Even if it entails killing and devouring their fellow bacteria.

“The punchline is: when things get tough, you eat your neighbors,” said Glen D’Souza, an Arizona State University molecular scientist and senior author of the paper published June 12 in the journal Science.

D’Souza explained that while most bacteria absorb nutrients from the environment around them, it’s “textbook behavior” for certain species to kill each other. However, what he and colleagues observed was something different. In some instances, usually harmless bacteria will turn to violence if desperate.

“What we’re seeing is that it’s not just important that the bacteria have weapons to kill, but they are controlling when they use those weapons specifically for situations to eat others where they can’t grow themselves,” D’Souza said.

“A microbial Jekyll and Hyde,” added Ferran Garcia-Pichel, ASU’s director of Biodesign Center for Fundamental and Applied Microbiomics who was not involved in the study.

D’Souza’s team focused on a specific process inside bacteria called the Type VI Secretion System (T6SS). Similar to a tiny harpoon gun, T6SS enables bacteria to shoot a microscopic, needlelike weapon loaded with toxins into neighboring cells and organisms, causing them to fatally tear apart. Previously, microbiologists believed that bacteria mostly used their T6SS to eradicate rivals and make space for their own growth.

But after utilizing timelapse imaging and other genetic analysis tools, the team recorded various bacteria using T6SS in a startling way. When nutrients were scarce, the organisms ambushed nearby bacteria and injected them with toxins. They then fed off of their targets as they essentially “bled out.”

“By slowly releasing nutrients from their neighbors, they maximize their nutrient harvesting when every molecule counts,” said study first author Astrid Stubbusch.

To prove that this behavior was, in fact, intentional, the team genetically switched off the T6SS in sample bacteria, and then placed them into a nutrient-starved setting. Those without the ability to use their mini-harpoons eventually died, but the unaltered bacteria began killing to survive.

“This isn’t just happening in the lab,” D’Souza clarified. “It’s present in many different environments and it’s operational and happening in nature from the oceans to the human gut.”

The ramifications go beyond microscopic horror stories. Understanding these systems allows researchers to gain a more complete picture of the microbial food chain and illustrate just how resourceful bacteria really are. It may also help pave the way for new antibiotics, or design drugs that harness T6SS to directly attack pathogens.

The observations also have implications outside the human body. Many ocean bacteria are responsible for helping regulate Earth’s carbon cycle. If some of them are using T6SS to devour bacteria that break down algae and recycle carbon, then ecologists can study how these influence planetary ecosystems.

“Watching these cells in action really drives home how resourceful bacteria can be,” added Stubbusch.

Advocates for good cause eviction protections, which prevent landlords from evicting tenants without a valid reason, have long faced pushback from developers who claim such laws discourage new construction. However, a new report from the University of Minnesota’s Center for Urban and Regional Affairs (CURA) finds no evidence that good cause policies reduce building permits or housing development.

The study compared counties in states with recently enacted good cause laws — such as California, Oregon, and New Hampshire — to neighboring regions without these protections. After accounting for economic variables, the researchers concluded that good cause policies had no impact on new construction.

Despite this data, resistance persists. In Maryland, where legislation to allow localities to adopt good cause failed to pass this year, opponents have shifted their arguments. Instead of focusing on whether good cause alone hurts development, they now argue that a combination of tenant protections — including rent stabilization and vacancy control — deters investment.

State Senator Will Smith, who played a key role in stalling the Maryland bill, claimed that while good cause alone may not harm housing, its combination with other protections does. However, critics argue that this is an attempt to undermine other tenant safeguards like vacancy control by linking them to good cause efforts.

Meanwhile, in Connecticut and Rhode Island, tenant advocates are using the CURA research to support their campaigns, though with mixed results. In Connecticut, the research helps counter objections but hasn’t shifted the broader debate centered around property rights. In Rhode Island, however, the data has influenced legislative commissions reviewing housing laws.

Advocates emphasize that while public support for good cause laws may come from lived experiences of housing insecurity, policymakers are more swayed by industry claims and developer pressure — despite lacking evidence. The continued repetition of developer narratives in media and politics, even after being debunked, underscores the challenge tenant advocates face in shifting public policy.

Bipedal, humanoid robots from companies like Boston Dynamics seemingly advance by the week, but they still can’t match their most audacious sci-fi inspirations. One of the major barriers they haven’t overcome is the ability to “feel” sensations like a human. Although researchers have tried various sensors to give robots a rudimentary sense of touch, these systems are often costly, inaccurate, and limited to detecting only one type of sensation at a time.

But that may be about to change. Researchers from the University of Cambridge and University College London have developed a new type of responsive “synthetic skin.” The skin is made from a single hydrogel that is capable of detecting touch, pressure, heat, cold, and damage in a way that more closely resembles human skin. 

The researchers were able to cast this gel into the mold of a hand and place it over a robot like a glove. By wearing the chunky flesh mitt, the robot can more accurately “feel” the world around it. Though still in the early stages, researchers say this type of synthetic skin could one day help robots work more effectively in factories, dangerous environments, or even assist in disaster relief efforts. The findings were published this week in the journal Science Robotics. 

Synthetic skin in robotics isn’t entirely new. Since as early as 2016, researchers have demonstrated the ability to use small sensors in robotic fingertips and hands to help them sense the shape and texture of certain objects. Until now though, that process would get quite complicated, quite quickly. A robotic hand capable of sensing both heat and pressure would require two different types of sensors—each designed to detect a specific sensation. These sensors can interfere with one another, causing what researchers call “cross talk.” Such mixed signals can also reduce the accuracy of perception and, in some cases, even damage the sensors. Adding more sensors to a small area like a robot hand also increases complexity, which raises the likelihood of errors.

“Having different sensors for different types of touch leads to materials that are complex to make,” lead author and Cambridge professor David Hardman said in a statement. “We wanted to develop a solution that can detect multiple types of touch at once, but in a single material.”

The researchers aimed to develop an alternative to the complicated multi-sensor approach by using a single material capable of detecting multiple types of stimuli. To do that, they used a soft, stretchable, and conductive gelatin-based hydrogel that can convert physical inputs, like heat and pressure, into electronic signals processed by a computer. According to the researchers, the gel itself is capable of detecting signals through 860,000 individual pathways embedded within the material. They conducted physical tests on the synthetic skin, exposing it to various types of stimuli at different levels to fine-tune its responsiveness.

That synthetic skin can also be melted down and reconfigured into new shapes. In this case, the researchers wanted to see if it would still function when molded into the shape of a human hand. The result was an odd-looking yellow-and-black hand resembling a battered construction glove. This glove was then placed over the robot’s hand. To test it, researchers pressed on it with a finger and lightly swabbed the surface. Even in this more realistic form, the skin was still able to differentiate between different levels of pressure.

From there, the researchers exposed the hand to a “heat blast,” partially melting it. They took the abuse a step further by using a scalpel to slice the hand open. Thanks to the synthetic skin, the glove was able to “feel” each different stimulus—all through a single, universal sensor. While it was still less responsive than human skin, it outperformed other approaches that rely on multiple sensors.

“We’re not quite at the level where the robotic skin is as good as human skin, but we think it’s better than anything else out there at the moment,” paper co-author and University College London researcher Thomas George Thuruthel said in a statement. “Our method is flexible and easier to build than traditional sensors, and we’re able to calibrate it using human touch for a range of tasks.”

The researchers say there’s a practical reason for all the poking, prodding, and burning their robot’s weathered hand. The tests demonstrate that, at least in theory, this synthetic skin could be melted down and molded to fit various parts of a robot’s body and still sense touch. A machine with this outer layer of sensing skin could then navigate its environment—whether in an automobile factory or on a construction site—and interact with the world in a way more similar to a human. That capability could become especially useful if humanoid robots, like those being developed by companies such as Figure and Tesla, are ever deployed to work alongside humans in real-world settings. If a robot is handing a car part to a human, it should probably know if it’s ripping hot.

Figure is already testing its humanoid robots in BMW’s South Carolina manufacturing facility. Amazon, meanwhile, is reportedly already training humanoid robots to carry and drop off packages to customers. 

An odd future where fleshy robots deliver your latest order of toilet paper, in other words, might not be all that far-fetched.

Very little in this life is truly random. A coin flip is influenced by the flipper’s force, its surrounding airflow, and gravity. Similar variables dictate rolling a pair of dice or shuffling a deck of cards, while even classical computing’s cryptographic algorithms are theoretically susceptible to outside influence or bias.

“True randomness is something that nothing in the universe can predict in advance,” explained Krister Shalm, a physicist at the National Institute of Standards and Technology (NIST).

So how does someone achieve true randomness? For that, you need to peer into the quantum realm. The task once required years of study and access to vast research facilities, but thanks to an ingenious new project from Shalm and his colleagues, now anyone can access a “factory for random numbers.” And it’s free to use.

Designed by NIST in collaboration with the University of Colorado Boulder, the Colorado University Randomness Beacon (CURBy) is a first-of-its-kind system that relies on headspinning quantum mechanics concepts to offer truly random number generation.

More specifically, CURBy’s foundation rests on a task known as the Bell test. Named after the famed physicist John Stewart Bell, the test measures pairs of entangled photons with properties that remain correlated even after separating across huge distances. While the outcome is always random when measuring a single particle, a pair’s properties are more correlated than classical physics dictates. This allows experts to verify the randomness at a quantum level.

Albert Einstein previously described this “quantum nonlocality” as “spooky action as a distance,” and he wasn’t a fan of the idea. Unfortunately for him, NIST proved its existence back in 2015. Three years later, they developed methodologies to use Bell tests in order to construct the world’s first true randomness generators.

These initial random results necessitated months of refinement and only ran for a few hours in total. Even then, the physicists and engineers only generated 512 bits of true randomness. Since then, researchers expanded and automated their experiment, thus offering random numbers whenever needed.

“We really wanted to take that experiment out of the lab and turn it into a useful public service,” said Shalm.

Their finalized protocol served up randomness 7,454 times over its first 40 days of existence. Researchers then recorded 7,434 cases of randomness—a success rate of 99.7 percent.

But how do you actually generate true randomness? For that, you need a system that relies on a bespoke nonlinear crystal to generate entangled photon pairs. The particles then speed away in an optical fiber to separate laboratories at opposite ends of a hallway at NIST. Once they reach the two labs, researchers measure their subsequent polarizations. This relay race is then repeated a headspinning 250,000 times per second.

All that data needs to be processed, so NIST sends off its millions of quantum coin flips to a specially designed computer program built by engineers at UC Boulder. The program then translates the measurements into 512 random bits of binary code that can then be parsed by anyone.

But utilizing CURBy is much simpler than the dizzying quantum computations required to generate true randomness. All a user needs to do is head to its website and key in the list of items you want shuffled. CURBy then will rearrange the entries based on any given day’s quantumly determined randomness. The outcome is decades in the making, and would have certainly given Einstein something to think about.

“I am at all events convinced that [the Creator] does not play dice,” he famously wrote to Max Born in 1926 regarding the concepts of quantum theory.

“If God does play dice with the universe, then you can turn that into the best random number generator that the universe allows,” Shalm said.

In a piece in the California Planning & Development Report, Josh Stephens makes the case that the decline of the Los Angeles film industry — “with 31% fewer filming days in 2024 compared to 2020” — is tied up with the city’s housing crisis.

"Fundamentally, entertainment and real estate must predict the future. Projects evolve on the order of years. They are capital-intensive, demanding up-front monies years before revenues come in, depending on the whims of consumers. Some projects appeal to urban aesthetes; others are family-friendly. Ultimately, audiences file into the theater or turn on the TV, inhabiting a fantasy for a little while. Residents and tenants move in, acting out their lives for months, years, or forever."

The loss of filming has significant ripple effects for the local economy. “Craftspeople are out of work. Support services like prop shops are closing. CBS recently sold Television City, its West Coast headquarters, which will be redeveloped. At least one entire studio lot -- the historic 20th Century Fox lot, now owned by Disney -- may be vacated, left to an uncertain fate.”

Meanwhile, housing remains unaffordable for many Angelenos. According to UCLA research, “Though Los Angeles recently adopted a massive housing-oriented rezoning program, called CHIPS, ‘Los Angeles will fall far short of its housing production goal’ and will risk ‘displacement of vulnerable households’ unless it supplements the rezoning with an ‘ambitious single-family upzoning policy.’”

Stephens concludes that “Hollywood needs to wake up. The need for housing -- via apartments, ADU's, transit-oriented development -- needs to go viral. Ideally, Hollywood should promote exactly the type of neighborhoods that it likes to shoot. Movies and TV shows disproportionately portray busy, walkable, attractive urban neighborhoods (see related CP&DR commentary) that are easy to create on a studio lot but almost impossible with conventional zoning, financing, and infrastructure. This is the moment when both of these once-great industries, with help from planners, need to recognize their common interests and flip this script.”

Public spaces are failing teenage girls, asserts Manish Thakre in an opinion piece for Next City. “A 2019 World Health Organization-led study suggests that 85% of school-going adolescent girls worldwide fail to meet the minimum recommended hour of daily physical activity.”

A U.K. study found that more than one million teen girls who considered themselves “sporty” stopped doing sports after primary school, with reasons including “ fear of judgment (68%), lack of confidence (61%), school pressures (47%) and not feeling safe outside (43%).” For Thakre, “These issues underscore the urgent need for gender-sensitive urban planning and recreation policies.”

The United Nations recognizes play and recreation as fundamental rights, Thakre adds. “UNICEF’s guidelines on child-responsive urban planning emphasize five core benefits for children: health, safety, citizenship, environment, and prosperity – yet these are often missing in city design.”

Thakre offers examples from Bath, England and Vienna, Austria, where city officials took concerted steps to prioritize the needs of teen girls in public spaces. “To foster inclusive and safe public spaces, cities must ensure safer streets and accessible open spaces like parks and playgrounds — working with adolescent girls to meet their needs.”
