The U.S. has suffered from devastating wildfires over the last few years as global temperatures rise and weather patterns change, making the otherwise natural phenomenon especially unpredictable and severe. To help out, Stanford researchers have found a way to track and predict dry, at-risk areas using machine learning and satellite imagery.

Currently the way forests and scrublands are tested for susceptibility to wildfires is by manually collecting branches and foliage and testing their water content. It’s accurate and reliable, but obviously also quite labor intensive and difficult to scale.

Fortunately, other sources of data have recently become available. The European Space Agency’s Sentinel and Landsat satellites have amassed a trove of imagery of the Earth’s surface that, when carefully analyzed, could provide a secondary source for assessing wildfire risk — and one no one has to risk getting splinters for.

This isn’t the first attempt to make this kind of observation from orbital imagery, but previous efforts relied heavily on visual measurements that are “extremely site-specific,” meaning the analysis method differs greatly depending on the location. No splinters, but still hard to scale. The advance leveraged by the Stanford team is the Sentinel satellites’ “synthetic aperture radar,” which can pierce the forest canopy and image the surface below.

“One of our big breakthroughs was to look at a newer set of satellites that are using much longer wavelengths, which allows the observations to be sensitive to water much deeper into the forest canopy and be directly representative of the fuel moisture content,” said senior author of the paper, Stanford ecoydrologist Alexandra Konings, in a news release.

The team fed this new imagery, collected regularly since 2016, to a machine learning model along with the manual measurements made by the U.S. Forest Service. This lets the model “learn” what particular features of the imagery correlate with the ground-truth measurements.

They then tested the resulting AI agent (the term is employed loosely) by having it make predictions based on old data for which they already knew the answers. It was accurate, but most so in scrublands, one of the most common biomes of the American west and also one of the most susceptible to wildfires.

You can see the results of the project in this interactive map showing the model’s prediction of dryness at different periods all over the western part of the country. That’s not so much for firefighters as a validation of the approach — but the same model, given up to date data, can make predictions about the upcoming wildfire season that could help the authorities make more informed decisions about controlled burns, danger areas, and safety warnings.

The researchers’ work was published in the journal Remote Sensing of Environment.

Brex, last valued at $2.6 billion, is restructuring its credit card for startups business and cut 62 staff members, the co-founders Pedro Franceschi and Henrique Dubugras said in a blog post.

“Today we’re restructuring the company to better align our priorities with this new reality, while simultaneously accelerating our product vision. With that, I have some very sad news to share. 62 people will be leaving Brex today,” the post reads.

The cuts come as Brex’s customer base itself is struggling to stay afloat amid COVID-19: high-growth startups. The trickle-down to Brex’s core business, which depends on its customers spending money, was thus expected.

Brex has already cut some customer credit limits to mitigate some of the exposure risk, The Information reported, and Dubugras confirmed. Customers say the credit limit cuts came without warning or notice.

Additionally, the company, launched in Brazil and graduated from Y Combinator, raised $150 million recently.

When TechCrunch talked to Dubugras about the latest fundraise, the co-founder said the capital was offensive, rather than defensive.

“I’m glad this round came together, but if it hadn’t, we would’ve been fine,” he said last week. “The capital is so we can play offensive while everyone else plays defensive.”

In the blog post, the co-founders wrote to former staffers.

“Please continue dreaming big and don’t lose the ambition that attracted you to Brex. Don’t let anything, not even a global pandemic, take that away from you. I wish we could give each one of you a hug, so instead I’ll end this message like I’d do it in Portuguese. Abraços, Pedro and Henrique.”

Those laid off will be provided with eight weeks of severance, their computer and equipment, and Brex will dedicate a part of its recruiting team to help find new opportunities for ex-staffers. Additionally, Brex is making adjustments to the equity cliff and has extended healthcare benefits through the end of 2020.

Brex has amassed $465 million in venture capital funding to date.

Sony has been dishing out details on the PlayStation 5 piece-by-piece, rather than dropping all of the details at one big mega event. First came word of the Holiday 2020 release window. Then came an overview of the specs — like that it’ll have a super fast solid state drive by default. Most recently, they showed off the controller. (The divvied up approach makes sense, really; with the ongoing pandemic preventing events like E3 and GDC from happening… why wouldn’t Sony work on their own schedule and make every aspect its own mini-spectacle?)

The next glimpse they give, it seems, will be of the first games coming to the console.

This morning Sony announced that they’ll be hosting a live-streamed event on June 4th at 1pm Pacific. In a blog post about the event, Sony Interactive CEO Jim Ryan clarifies the focus:

We’ve shared technical specifications and shown you the new DualSense wireless controller. But what is a launch without games?

That’s why I’m excited to share that we will soon give you a first look at the games you’ll be playing after PlayStation 5 launches this holiday.

Ryan also notes that the event should last roughly an hour, but doesn’t suggest how many different games that’ll cover.

In a video that managed to pull in millions of views, Epic Games recently gave a first look at its upcoming Unreal Engine 5 running on pre-release PS5 hardware. Given that video’s success, I’d imagine that Sony is pretty dang eager to keep the early looks coming.

Will we finally see the console hardware itself? That’s still unclear. Seeing as they’ve pieced just about everything else out, though, I’d bet they’re saving that one for an event a bit closer to launch.

When this editor first met Jeremy Conrad, it was in 2014, at the 8,000-square-foot former fish factory that was home to Lemnos, a hardware-focused venture firm that Conrad had cofounded three years earlier.

Conrad —  who as a mechanical engineering undergrad at MIT worked on self driving cars, drones and satellites — was still excited about investing in hardware startups, having just closed a small new fund even while hardware was very unfashionable. One investment his team had made around that time was in Airware, a company that made subscription-based software for drones and attracted meaningful buzz and $118 million in venture funding before abruptly shutting down in 2018.

For his part, Conrad had already moved on, deciding in late 2017 that one of the many nascent teams that was camping out at Lemnos was on to a big idea relating the future of construction. Conrad didn’t have a background in real estate per se or even an earlier interest in the industry. But the “more I learned about it — not dissimilar to when I started Lemnos — It felt like there was a gap in the market, an opportunity that people were missing,” says Conrad from his home in San Francisco, where he has hunkered down throughout the COVID-19 crisis.

Enter Quartz, Conrad’s now 1.5-year-old, 14-person company, which quietly announced $7.75 million in Series A funding earlier this month, led by Baseline Ventures, with Felicis Ventures, Lemnos and Bloomberg Beta also participating.

What it’s selling to real estate developers, project managers and construction supervisors is really two things, which is safety and information. Using off-the-shelf hardware components that are reassembled in San Francisco and hardened (meaning secured to reduce vulnerabilities), the company incorporates its machine-learning software into this camera-based platform, then mounts the system onto cranes a construction sites. From there, the system streams 4K live feeds of what’s happening on the ground, while also making sense of the action.

Say dozens of concrete pouring trucks are expected on a construction site. The cameras, with their persistent view, can convey through a dashboard system whether and when the trucks have arrived and how many, says Conrad. It can determine how many people on are on a job site, and whether other deliveries have been made, even if not with a high degree of specificity. “We can’t say [to project managers] that 1,000 screws were delivered, but we can let them know whether the boxes they were expecting were delivered and where they were left,” he explains.

It’s an especially appealing proposition in the age of coronavirus, as the technology can help convey information that’s happening at a site that’s been shut down, or even how closely employees are gathered. Conrad says the technology also saves on time by providing information to those who might not otherwise be able to access it. Think of the developer who is on the 50th floor of the skyscraper he or she is building, or even the crane operator who is perhaps moving a two-ton object and has to rely on someone on the ground to deliver directions but can enjoy far more visibility with the aid of a multi-camera set-up.

Quartz, which today operates in California but is embarking on a nationwide rollout, was largely inspired by what Conrad was seeing in the world of self-driving. From sensors to self-perception systems, he knew the technologies would be even easier to deploy at construction sites, and he believed it could make them safer, too. Indeed, like cars, construction sites are astonishingly dangerous. According to the Occupational Safety and Health Administration, of the worker fatalities in private industry in 2018, more than 20% were in construction.

Conrad also saw an opportunity to take on established companies like Trimble, a 42-year-old, publicly traded, Sunnyvale, Ca.-based company that sells a portfolio of tools to the construction industry and charges top dollar for them, too. (Quartz is currently charging $2,000 per month per construction site for its series of cameras, their installation, a livestream and “lookback” data, though this may well rise at its adds additional features.)

It’s a big enough opportunity in fact, that Quartz is not alone in chasing it. Last summer, for example, Versatile, an Israeli-based startup with offices in San Francisco and New York City, raised $5.5 million in seed funding from Germany’s Robert Bosch Venture Capital and several other investors for a very similar platform,  though it uses sensors mounted under the hook of a crane to provide information about what’s happening. Construction Dive, a media property that’s dedicated to the industry, highlights many other, similar and competitive startups in the space, too.

Still, Quartz has Conrad, who isn’t just any founding CEO. Not only does he have that background in engineering, but having founded a venture firm and spent years as an investor may serve him well, too. He thinks a lot about the payback period on its hardware, for example.

Unlike a lot of founders, he also says he loves the fundraising process. “I get the highest quality feedback from some of the smartest people I know, which really helps focus your vision,” says Conrad, who says that Quartz, which operates in California today, is now embarking on a nationwide rollout.

“When you talk with great VCs, they ask great questions. For me, it’s best free consulting you can get.”

The global spread of COVID-19 and resulting orders to shelter in place have hit retailers hard.

As the pandemic drags on, temporary halts are becoming permanent closures, whether it’s the coffee shop next door, an historic bar, or a well-known lifestyle brand.

But while the present is largely bleak, preparing for the future has retailers adopting technologies faster than ever. Their resilience and innovation means retail will look and fee different when the world reopens.

We gathered four views on the future of retail from the TechCrunch team:

• Natasha Mascarenhas says retailers will need to find new ways to sell aspirational products — and what was once cringe might now be considered innovative.
• Devin Coldewey sees businesses adopting a slew of creative digital services to prepare for the future and empower them without Amazon’s platform.
• Greg Kumparak thinks the delivery and curbside pickup trends will move from pandemic-essentials to everyday occurrences. He thinks that retailers will need to find new ways to appeal to consumers in a “shopping-by-proxy” world.
• Lucas Matney views a revitalized interest in technology around the checkout process, as retailers look for ways to make the purchasing experience more seamless (and less high-touch).

Alexa, how do I look?

SpaceX had just conducted yet another static fire test of the Raptor engine in its Starship SN4 prototype launch vehicle on Friday when the test vehicle exploded on the test stand. This was the fourth static fire test of this engine on this prototype, so it’s unclear what went wrong vs. other static fire attempts.

This was a test in the development of Starship, a new spacecraft that SpaceX has been developing in Boca Chica, Florida. Eventually, the company hopes to use it to replace its Falcon 9 and Falcon Heavy rocket, but Starship is still very early in its development phase, whereas those vehicles are flight-proven, multiple times over.

SpaceX had just secured FAA approval to fly its Starship prototype for short, suborbital test flights earlier this week. The goal was to fly this SN4 prototype for short distances following static fire testing, but that clearly won’t be possible now, as the vehicle appears to have been completely destroyed in the explosion following Friday’s test, as you can see below in the stream from NASASpaceflight.com.

The explosion occurred around 1:49 PM local time in Texas, roughly two minutes after it had completed its engine test fire. We’ve reached out to SpaceX to find out more about the cause of today’s incident, and whether anyone was potentially hurt in the explosion. SpaceX typically takes plenty of safety precautions when running these tests, including ensuring the area is well clear of any personnel or other individuals.

This isn’t the first time one of SpaceX’s Starship prototypes has met a catastrophic end; a couple of previous test vehicles succumbed to pressure testing while being put through their paces. This is why space companies test frequently and stress test vehicles during development – to ensure that the final operational vehicles are incredibly safe and reliable when they need to be.

SpaceX is already working on additional prototypes, including assembling SN5 nearby in Boa Chica, so it’s likely to resume its testing program quickly once it can clear the test stand and move in the newest prototype. This is a completely separate endeavor from SpaceX’s work on the Commercial Crew program, so that historic first test launch with astronauts on board should proceed either Saturday or Sunday as planned, depending on weather.

Today, the online film festival We Are One is kicking off 10 days of films, talks, musical performances and VR experiences.

The event is a collaboration between Tribeca Enterprises (the organization behind the Tribeca Film Festival) and YouTube, with help from 21 film festivals.

Think of it as an attempt to recreate some of the excitement of this year’s canceled festivals, and to showcase some of the films that would have screen there. Partner festivals include the Berlin International Film Festival, the Cannes Film Festival, the Sundance Film Festival, the Toronto Film Festival and the Venice Film Festival.

YouTube Chief Business Officer Robert Kyncl credited Tribeca for doing the “heavy lifting” of bringing all the festivals on-board and curating the lineup. He said that when Tribeca’s co-founder and CEO Jane Rosenthal first approached YouTube with the idea, “It sounded great to us, but it seemed impossible to actually execute — to get all of these important people around the world to agree to this one thing.”

However, Rosenthal and her team were able to pull it everything together in a short period of time, so YouTube is giving its part by giving the festival its online home. There will be more than 100 films screening on a schedule, just like a regular festival — although after many of the movies premiere, they will be available on-demand after it premieres for the duration of the event.

And again, it’s not just films, but the other festival programming too, like Tribeca Talks with directors like Guillermo del Toro and Francis Ford Coppola. YouTube channels like Lessons from the Screenplay, CineFix, Now You See It and La Blogotheque have also gotten involved by creating new content for the festival.

All the content is available for free, and Kyncl said that neither YouTube nor Tribeca is monetizing the event. Instead, they’re directing viewers to donate to COVID-19 relief efforts, including the World Health Organization, UNICEF, UNHCR, Save the Children, Doctors Without Borders, Leket Israel, GO Foundation and Give2Asia.

“We just see this as an immediate response with no commercial intent on our side,” he said.

And while We Are One was created in response to the COVID-19 pandemic, Kyncl sounds hopeful that there could be similar online festivals in the future — not that any online experience can fully replace the “human connection” of an in-person festival.

“The role that youTube can play for all the festivals in the future is, we can extend their reach … whether it’s creators who may be participants in their film festivals in the future, or just audiences who are absolutely participating, but I think we can expand their universe in any way they wish,” Kyncl said. But he added, “We’ve given zero thought given to it thus far. We’re all focused on making sure we can pull this off in short amount of time.”

Box CEO Aaron Levie has been working to change the software world for 15 years, but the pandemic has accelerated the move to cloud services much faster than anyone imagined. As he pointed out yesterday in an Extra Crunch Live interview, who would have thought three months ago that businesses like yoga and cooking classes would have moved online — but here we are.

Levie says we are just beginning to see the range of what’s possible because circumstances are forcing us to move to the cloud much faster than most businesses probably would have without the pandemic acting as a change agent.

“Overall, what we’re going to see is that anything that can become digital probably will be in a much more accelerated way than we’ve ever seen before,” Levie said.

Fellow TechCrunch reporter Jon Shieber and I spent an hour chatting with Levie about how digital transformation is accelerating in general, how Box is coping with that internally and externally, his advice for founders in an economic crisis and what life might be like when we return to our offices.

Our interview was broadcast on YouTube and we have included the embed below.

Just a note that Extra Crunch Live is our new virtual speaker series for Extra Crunch members.

On digital transformation

The way that we think about digital transformation is that much of the world has a whole bunch of processes and ways of working — ways of communicating and ways of collaborating where if those business processes or that way we worked were able to be done in digital forms or in the cloud, you’d actually be more productive, more secure and you’d be able to serve your customers better. You’d be able to automate more business processes.

We think we’re [in] an environment that anything that can be digitized probably will be. Certainly as this pandemic has reinforced, we have way too many manual processes in businesses. We have way too slow ways of working together and collaborating. And we know that we’re going to move more and more of that to digital platforms.

In some cases, it’s simple, like moving to being able to do video conferences and being able to collaborate virtually. Some of it will become more advanced. How do I begin to automate things like client onboarding processes or doing research in a life sciences organization or delivering telemedicine digitally, but overall, what we’re going to see is that anything that can become digital probably will be in a much more accelerated way than we’ve ever seen before.

How the pandemic is driving change faster
