It's long been thought that the type-2 diabetes drug taken by an estimated 20 million Americans was doing its heavy lifting in the liver, suppressing the production of glucose to regulate blood sugar. But new research has uncovered it's actually working its magic in the gut – which opens the door to the possibility of finding new compounds that perform the same function.

Originally envisioned as a Tesla Model 3 hatch camper, the all-new Wheelhome Dashaway ECT micro-camping trailer series eventually earned its own wheels. It's still aimed at efficient all-electric camping trips but is able to furnish travelers with a surprising number of amenities, giving an adventurer or two everything they need to survive in comfort: a cozy lounge-cum-bedroom, a high-efficiency kitchen, cargo storage and even a toilet room, all in a pop-up wedge-shaped vessel inspired by a rooftop tent.

Canon has posted a video to its social media, which appears to tease an upcoming announcement.
The company says something is coming on May 13th at 9AM ET (6AM PT, 1PM GMT), with the caption "One camera. Endless possibilities." The post shows a person staring at a camera that is, as is often the case in these videos, cloaked in shadow, though a red tally lamp shines brightly from it. That detail, and the fact that, on Instagram, the post is a collaboration between Canon's main and Pro Video accounts, implies that we'll likely see something video-related.
This is the second teaser we've seen from a major camera company regarding an announcement on May 13th, which is, at time of writing, next Wednesday; Sony also posted a teaser for "the next R." Whatever the two companies are cooking up, it seems like the camera drought of 2026 may be coming to an end.
Sony has announced an event for next week via its social accounts, teasing "the next R." The video and Instagram post share that the event will take place on May 13th at 9:30 EDT / 14:30 BST / 22:30 JST.
Sony isn't sharing anything beyond that there will be an event, and the date and time. Unlike many teasers, the posts don't feature a blurred-out or silhouetted camera or lens that we can try to glean details from. However, the mention of "the next R" certainly doesn't leave much up to the imagination, at least in terms of which lineup is likely to benefit from the upcoming event.
In an Instagram post a few days earlier, Sony unveiled a separate upcoming community event called Alpha in Residence, happening in New York City on May 14-15. Alpha in Residence is a two-day event that will feature photowalks, styled shooting sets in a historic mansion, gear rentals, panel discussions and more. It is free, though you do need to register for a ticket, which you can do on Sony's website.

Favorite camera and lens: Brian primarily uses a Nikon Z5 with a Nikkor DX 16–50mm f/3.5–6.3 VR lens for his walk-around photography. For special architectural projects, he keeps a Nikkor Z24–70 f/4 lens on hand. He values the Z5 for its manageable size and the 24MP resolution, which suits the level of detail he requires without adding unnecessary weight. His setup emphasizes practicality and comfort, allowing him to focus on composing images rather than being encumbered by heavy gear.
"I find the Nikon Z5 just the right size (a little lighter weight would be nice). 24MP is fine for me, it has the right level of controls and seems to suit how I work."

My controversial camera choice"This might raise a few eyebrows, but I’ve settled on a Nikon Z5 with a modest Nikkor DX 16–50mm lens for most of my photography. It’s a far cry from the heavier, higher-end gear I used when I was photographing architectural projects for clients in northern England and London. Over the years, I worked with everything from Nikon D600s and D750s to two Z5s with wide and standard zooms and even a Fujifilm XT2."
"Yes, my images are effectively 10MP from this DX lens setup, but that’s perfectly fine for me. It may seem like a compromise, but for me, the joy is in taking the shot itself. I still keep a Z24–70 f/4 for special projects, and I’ve dabbled in a Viltrox 85mm f/1.8 for family portraits – though it had a slight mounting fault that needed repair (which, of course, was just outside the warranty period)."

"I’m most interested in the architecture of towns and cities across northern Europe. Since retirement, I have been traveling through parts of northern Europe, planning my trips carefully in advance to visit selected projects in Vienna, Budapest, Barcelona, Prague, Paris, Istanbul, Amsterdam, Athens, Bologna, Florence, Riola, Lisbon, Cordoba, and more, plus London, Glasgow, Oxford, Cambridge, Wells, Tewkesbury, Gloucester, Durham, Worcester and many others. In fact, I just had a day in Durham and am due to go to Helsinki for 10 days at the end of May 2026 – if my airline can find aviation fuel."
I just had a day in Durham and am due to go to Helsinki for 10 days at the end of May 2026 – if my airline can find aviation fuel. How has your camera gear evolved alongside your photography?"Starting from basic holiday 'snaps,' I quickly had to learn, after joining the School of Architecture in Nottingham, how to photograph streetscapes, individual buildings, sites, and architectural models, to produce photos that could stand up to serious scrutiny and criticism. I also taught myself to develop and print in makeshift darkrooms."
"My early cameras, bought second-hand on a student grant, included an English Corfield 'Periflex' Gold Star 35mm, followed by a Yashica SLR with clip-on exposure meter (which I later regretted parting with for an Olympus Pen-F). I then tried Minolta, Samsung, and Pentax film cameras before finally settling on Nikon, culminating in my current Z5."

"In May 2025, I went with an architect friend to Barcelona, which I found to be an architectural wonderland. We visited and photographed works by Antoni Gaudi, of course, but by pre-planning we were also able to visit a number of other projects including the IMO Eye Hospital by Josep Llinas, The University of Pompeu Fabra Library which is a spectacular arcaded masonry structure, the Santa Caterina Market, a neo-classical building refurbished by Enrique Miralles and the Fira de Belacaire flea market with spectacular fragmented mirrored canopy."
What Nikon Z5 camera modes work best for architectural shots?"Very occasionally, I set my camera on a firm base (if I can find a suitable area) to shoot nighttime / dark shots using modes U1 and U2, with the second delayed shutter release."
"I have the user modes set up as follows:
"All with matrix metering. I shoot almost exclusively hand-held now, and often in quite dark or very dark interiors, so I need auto-ISO set to max 6400."

Newly observed negative-phase waveforms in earthquake data have alerted scientists to a previously unrecognized feature of the "big ones" to do with tectonic plates slipping by each other: they create a kind of geological 'whiplash' that happens when a rupturing fault movement abruptly stops.

Nikon has announced it is developing a 120-300mm F2.8 zoom lens with a built-in 1.4x teleconverter.
The Nikkor Z 120-300mm F2.8 TC VR S will not only offer a longer alternative to a traditional 70-200mm F2.8 but, at the flick of a switch, will turn into a 168-420mm F4, extending its reach and its flexibility.
No further details have been revealed, other than reference to the needs of professional photographers which, along with the S series designation, is likely to give an indication of a fairly substantial price tag. The announcement has been accompanied by a pretty final-looking product rendering, so we doubt we'll have to wait long to find out more.
Nikon already has an 'S-Line' 100-400mm F4.5-5.6 variable aperture zoom, which has a list price of $3000, but we suspect a more meaningful reference point is the Nikkor Z 400mm F2.8 TC VR S, which was launched for $14,700.
Anyone who's used one of Nikon's recent lenses with the built-in TC is likely to be trying not to think too much about the reassuringly damped 'thunk' as the large thumb switch on the side of the barrel slots the teleconverter into place.
Nikon is developing the NIKKOR Z 120-300mm f/2.8 TC VR S, a telephoto zoom lens with a built-in 1.4× teleconverterMELVILLE, NY (May 7, 2026) -- Nikon is pleased to announce the development of the NIKKOR Z 120-300mm f/2.8 TC VR S, a telephoto zoom lens compatible with full-frame/FX-format mirrorless cameras.
As part of the S-Line* series of NIKKOR Z lenses, the NIKKOR Z 120-300mm f/2.8 TC VR S is a telephoto zoom lens offering a focal length range of 120mm to 420mm, enabled by a built-in teleconverter that extends its focal length by 1.4×. The superior optical performance and mobility of this lens will support professional photographers' imaging expression in genres such as sports photography and beyond.
Nikon will continue to pursue a new dimension in optical performance while meeting users' needs, contributing to the development of imaging culture, with the hope of expanding possibilities for imaging expression.
For more information about the latest Nikon products, including the vast collection of NIKKOR Z lenses and the entire line of Z series cameras, please visit nikonusa.com.
*The S-Line is a grade of NIKKOR Z lenses that demonstrate outstanding optical performance, adhering to a high standard of design principles and quality control.
A year ago, we took a look at the Crosspeak 2 tent from Hyperlite Mountain Gear. The impressive cut of Dyneema fabric weighed in barely over 2 pounds (907 g), adding yet another intriguing option to an ultralight freestanding tent market that was running white hot at the time. On the downside, it cost more than a dollar per gram. Now Hyperlite has launched the solo version: the Crosspeak 1. The new Dyneema freestander drops well below 2 lb to become one of the lightest out there and also gets a lower price ... but it still follows the same dollar-per-gram+ pricing model.

It's no secret that NASA is careful about the technology it uses on missions, including anything camera-related. After all, space is the epitome of an extreme environment, and it's important to perform thorough testing to ensure devices can function despite those challenges. A recently surfaced NASA presentation, highlighted by Digital Camera World, provides a glimpse at that process.
The 2022 presentation, titled "Handheld Camera (HHC) Initial Test Results," is available through NASA's Technical Reports Server and evaluates the performance of the Canon EOS R5, Nikon D6 and Nikon Z7II in a vacuum chamber that could also heat and cool the cameras. The presentation includes images of the testing procedures and details how the team performed the tests. It's worth noting that the team clarifies that the Nikon Z9 was not available during the thermal-vacuum testing period.
A slide from the presentation detailing parts of the testing procedure.
Slide: Jonathan E Pryor, Marshall Space Flight Center
The headline result is that the Canon R5 and Nikon D6 both survived vacuum testing and operated across a temperature range of -30°C to +40°C (-22°F to +104°F), with NASA noting that the two cameras showed "similar operational characteristics" across that range. It's important to note, too, that these were unmodified, off-the-shelf versions of those cameras. It turns out stock cameras are tougher than you may have assumed.
Before testing, the cameras and supporting hardware were heated to 50°C (122°F) for 72 hours in a process known as a bakeout, which helps drive off volatile materials before equipment is placed in a vacuum chamber. The cameras were then placed inside a temperature-controlled enclosure within the chamber, while Wi-Fi and Bluetooth were used to control image and video capture.
The slide detailing the results of some of the testing.
Slide: Jonathan E Pryor, Marshall Space Flight Center
The cameras were tested in both stills and video modes, though the D6 didn't undergo the same full set of video tests as the R5. In the hotter video tests, the R5 recorded until it overheated and shut itself down, then was given five-minute cool-down periods before testing continued. The researchers did not perform the second and third D6 video tests out of concern that it might lose connection in the same way as the Z7II (detailed below). Even so, NASA's results suggest both the R5 and D6 were usable in the chamber, with the caveat that the D6's video performance was not explored as extensively.
The Nikon Z7II, meanwhile, did not complete the same full temperature range. The presentation says it worked at ambient temperature, but under near-vacuum conditions, it lost connection after recording video and could not reconnect. The camera didn't outright fail, but a device used in space needs to be able to be reliably controlled, especially if there are plans for remote operation.
Details of the stills performances of the R5 and D6.
Slide: Jonathan E Pryor, Marshall Space Flight Center
Another practical problem that the test highlights: remembering to turn Raw files on. The D6 was set up to capture both Raw and JPEG images, and the R5 was supposed to be the same. Unfortunately, the presentation calls out that the "setting was missed during setup process," so it only recorded JPEGs. Next time you discover after a shoot that your camera was set to JPEG only, just remind yourself that even NASA researchers do that.
In addition to camera testing, the deck also includes radiation testing of four CFexpress card brands: Lexar, SanDisk, ProGrade and Sony. SanDisk showed the best result in NASA's calculations, but the presentation strongly warns that the outcome depends on the exact test setup and amount of radiation used, and should not be treated as a buying recommendation. None of the cards completely failed; NASA says temporary radiation-related errors were resolved by power cycling the cards.
A slide from the 2024 presentation detailing camera modifications.
Slide: Parker Weide
The 2022 presentation is especially interesting in light of NASA's later work on a dedicated lunar camera. In 2024, NASA published a paper on testing a modified commercial camera for lunar environments. It concludes that the camera and its thermal protection system continued to function under most simulated conditions, but highlights issues such as LCD screen ghosting and overheating in extreme environmental conditions. NASA has since said its Handheld Universal Lunar Camera, or HULC, is based on a modified Nikon Z9 with Nikkor lenses, a protective thermal blanket, modified electronics and a custom grip designed for astronauts wearing spacesuit gloves.
