Slide, Spiral, Learn: Bernard Tschumi Completes a Science Centre Built on Motion

Posted on by

A science centre that asks students to slide between floors is either a gimmick or a statement. At Institut Le Rosey, it’s unmistakably the latter. Philo, the newly completed science and innovation centre by Bernard Tschumi Architects in Rolle, near Geneva, brings that idea to life with an architectural precision that feels entirely intentional.

The building, which took shape between 2019 and 2025, sits on the campus of one of Switzerland’s most prestigious international boarding schools, right alongside Carnal Hall, the metal-domed music venue Tschumi completed for the same institution back in 2014. Where Carnal Hall curves inward with acoustic purpose, Philo opens up — a ring-shaped structure five storeys tall, wrapping itself around a grand central atrium that functions less like a corridor and more like a covered public square.

Designer: Bernard Tschumi Architects

That atrium is the building’s beating heart. Three concentric walkways surround it, and vertical and horizontal circulation paths cut through the space, generating constant movement. Helical slides thread through the interior alongside the sculptural spiral staircase, turning the everyday act of moving between floors into something worth doing. It sounds playful — and it is —, but it’s also deeply considered. Tschumi has spent decades arguing that architecture only comes alive through movement and event, and Philo reads like a direct translation of that thinking into built form.

The programme inside is built around student innovation. Philo houses a Fabrication Lab, a Start-up Incubator Space, and a Pitch Room — a flexible rectangular space that can be reconfigured for presentations or performances. Classrooms and laboratories fill the remaining floors, all oriented around the central void. The result is a building that doesn’t separate learning from making, or thinking from doing. Every space feels connected, both literally and conceptually.

Externally, the ring form gives Philo a strong presence on campus without overpowering it. The circular geometry creates a clear dialogue with Carnal Hall’s dome, establishing a coherent architectural language across two very different building types. Aerial photography by Iwan Baan captures just how deliberately the two structures have been positioned — companions on a campus that now has a genuine architectural identity.

Philo isn’t trying to reinvent education. What it does, with impressive restraint, is create the conditions for a different kind of learning — one built on movement, collision, and chance encounter. For a studio whose founder once wrote that there is no architecture without events, it’s a building that lives up to the theory.

NASA’s initial takeaways from the Artemis II mission, and more science stories

Posted on by

Now that Artemis II is all wrapped up, NASA has begun its post-game performance analyses of all the systems that worked together to get four astronauts safely to the moon and back earlier this month. In addition to taking humans farther than ever before, Artemis II served as a crucial test flight for upcoming crewed missions that are planned for as soon as 2027 and 2028, the latter being NASA's ambitious target for landing astronauts on the lunar surface. So far, the Orion spacecraft and the SLS rocket seem to have fared pretty well. 

NASA says its initial assessments of the crew capsule show its heat shield "performed as expected, with no unusual conditions identified," and it didn't exhibit as much char loss as seen in the uncrewed Artemis I test. (Navy divers snapped some really cool pictures of the heat shield underwater after splashdown, as seen below). Splashdown went according to plan, with Orion landing 2.9 miles from its targeted landing site, according to NASA, and its entry interface velocity "was within one mile-per-hour of predictions."

NASA says the SLS rocket performed well, too. It still has tests to run, but, "At main engine cutoff, when the core stage’s RS-25 liquid engines shutdown, the spacecraft was traveling at over 18,000 miles per hour, achieving its insertion velocity for orbit, and executing a precise bullseye for its intended location," the space agency noted in a blog post.

One thing that we know did cause some issues, though, was the toilet system. Shortly after launch, the astronauts reported problems with the urine vent line, which mission specialist Christina Koch was able to troubleshoot with help from the ground crew. But, everyone would like to avoid that on the next mission, so NASA now has teams checking out the hardware and data to identify what went wrong and how to prevent it. 

The Artemis II astronauts have continued to share glimpses into their journey around the moon, and this week, the mission's commander, Reid Wiseman posted an incredible video of the Earth setting behind the moon, as seen from the Orion spacecraft. Humans haven't seen that phenomenon firsthand in over 50 years, since the last Apollo mission. Read more about that here. 

While ten days might not seem like that long of a time to be in space, it still does things to the body, and returning to Earth has been a bit of an adjustment for the crew. Astronaut Koch last week posted a video of herself struggling through a tandem walk exercise with her eyes closed, taken after her return to Earth. "When people live in microgravity, the systems in our body that have evolved to tell our brains how we’re moving, the vestibular organs, don’t work correctly," she explained in the caption. "Our brains learn to ignore those signals and so when we first get back to gravity, we are heavily reliant on our eyes to orient ourselves visually."

NASA targets a September launch for its next big space telescope

Posted on by

NASA's next eye into the cosmos is due to leave our planet later this year. The agency says it's targeting an early September launch for the Nancy Grace Roman Space Telescope. Roman (for short) has a field of view 100 times larger than Hubble's.

The September date is the earliest possible launch for Roman. NASA says it will go up (aboard a SpaceX Falcon Heavy rocket) no later than May 2027.

The Nancy Grace Roman Space Telescope, named after NASA's first chief astronomer and "mother" of Hubble, was introduced in 2016. (Back then, it was known as the Wide Field Infrared Survey Telescope, or WFIRST.) The telescope's mirror is roughly the same size as Hubble's, but it can capture sections of the sky at least 100 times larger than its predecessor.

"Roman will work in tandem with NASA observatories such as the James Webb Space Telescope and Chandra X-ray Observatory, which are designed to zoom in on rare transient objects once they've been identified, but seldom if ever discover them," Julie McEnery, Roman's senior project scientist, said in 2023. "Roman's much larger field of view will reveal many such objects that were previously unknown. And since we've never had an observatory like this scanning the cosmos before, we could even find entirely new classes of objects and events."

After leaving our atmosphere, Roman will set course for a vantage point nearly 1 million miles from Earth. There, it will rely on a pair of instruments to study space. The first is a 300.8-megapixel camera that captures light from visible to near-infrared. There's also a high-contrast coronagraph that will allow it to capture exoplanets that would otherwise be blocked by starlight.

Roman’s mission: "to settle essential questions in the areas of dark energy, exoplanets and astrophysics." Despite decades of study, astronomers know surprisingly little about dark energy, which makes up about 68 percent of the universe’s contents. And while scientific discoveries are cool and all, you’ll be pleased to know that Roman is also sure to beam back more dazzling pictures of our cosmos.

NASA’s Curiosity Rover found promising organic chemicals on Mars

Posted on by

The search for signs of life on Mars continues to yield promising data. A first-of-its-kind wet chemistry experiment, published Tuesday in Nature, confirmed the presence of essential ingredients of life preserved in ancient Martian sandstones.

The molecules were found inside 3.5-billion-year-old sandstone. NASA's Curiosity rover collected the clay-filled rocks from an area called Glen Torridon, inside Mars' enormous Gale Crater. The rover's Sample Analysis at Mars (SAM) mobile instrument suite analyzed the data.

The experiment was unique as the first off-Earth study to use the chemical tetramethylammonium hydroxide (TMAH). The reagent allows Curiosity to break down larger organic molecules on the Martian surface, reducing them to something the rover's instruments can read.

It revealed the presence of over 20 different organic molecules. Among the data was confirmation of naphthalene and benzothiophene, some of the largest and most complex organic compounds discovered on the Red Planet. The experiment also yielded the first detection of a possible N-heterocycles, which DNA and RNA are built upon.

“That detection is pretty profound because these structures can be chemical precursors to more complex nitrogen-bearing molecules,” the paper’s lead author, Amy Williams, wrote in NASA’s announcement. “Nitrogen heterocycles have never been found before on the Martian surface or confirmed in Martian meteorites.”

As with previous discoveries of organic material on Mars, this one is not yet the smoking gun we've been waiting for. But it adds to a growing body of evidence that, at a minimum, the foundations of life as we know it were present on an ancient version of the planet. The study also confirms that organic material can survive on Mars for billions of years, which will encourage future experiments.

The paper's authors say the data will help NASA to optimize its second (and final) TMAH experiment on Curiosity. It also opens the door to future TMAH tests on the Rosalind Franklin Mars rover and the Dragonfly mission to Saturn's moon, Titan. Both missions are scheduled for 2028 at the earliest.
