Robert Jarvik, a Designer of the First Artificial Heart, Dies at 79

Robert Jarvik, a Designer of the First Artificial Heart, Dies at 79
Robert Jarvik, the brilliant medical innovator behind the Jarvik-7—the first artificial heart to be successfully implanted in a human—has passed away at 79. His groundbreaking work in the 1980s paved the way for modern heart-assist technologies, offering hope to countless patients with severe heart disease. While the early devices had limitations, Jarvik’s relentless tinkering and vision laid the foundation for today’s life-saving artificial organs.
Editor’s Note: Jarvik’s legacy isn’t just about a single device—it’s about pushing the boundaries of what’s possible in medicine. His work forced the world to grapple with big questions: How far should we go to extend human life? Can machines truly replace biology? Even decades later, his influence echoes in every ventricular assist device and artificial heart keeping patients alive today. For anyone whose life has been touched by cardiac care, Jarvik’s story is a reminder of how one stubborn, creative mind can change the game.

Shubhanshu Shukla’s Axiom 4 launch delayed again; Nasa cites safety checks; new date expected soon
neutralScience
NASA has hit pause on the Axiom Mission 4 launch to the International Space Station (ISS), where Indian astronaut Shubhanshu Shukla was set to make history. The delay comes as engineers double-check recent repairs on the Zvezda service module—essentially making sure the ISS is in tip-top shape before welcoming the new crew, which also includes astronauts from Poland and Hungary. A new launch date is expected soon, but for now, safety takes priority.
Editor’s Note: Delays in space missions are frustrating, especially for high-profile launches like this one, but they’re also a reminder of how seriously NASA takes astronaut safety. For Shukla and his international crewmates, it’s a temporary setback—better to wait than risk a problem in orbit. The story also highlights the growing global collaboration in space, with India, Poland, and Hungary all part of this mission. Patience is key when it comes to space travel.

Is Mars really red? A physicist explains the planet’s reddish hue and why it looks different to some telescopes
neutralScience
Turns out, Mars isn’t quite as red as it seems—at least not all the time. A physicist breaks down why the planet’s famous rusty hue can look different depending on how you’re observing it, whether through a telescope, a rover’s camera, or even the naked eye. The color shifts come down to dust, light, and a sprinkle of cosmic illusion.
Editor’s Note: Mars has always been this mysterious red dot in the sky, but this piece peels back the curtain on why its color isn’t as straightforward as we think. It’s a cool reminder that even the simplest things—like a planet’s color—can have layers of science behind them. Plus, it’s a neat example of how perspective (and technology) shapes what we “know” about space.

Mathematicians discover a completely new way to find prime numbers
positiveScience
Mathematicians have stumbled onto a fresh approach to identifying prime numbers—those elusive building blocks of math—by tapping into something called "integer partitions." Even cooler, this method unexpectedly bridges two seemingly unrelated areas of mathematics, hinting at deeper connections we didn’t see before.
Editor’s Note: Primes are like the atoms of the number world, but finding them has always been a mix of brute force and clever tricks. This breakthrough isn’t just about spotting primes faster—it’s a reminder that math still holds surprises, and sometimes the most elegant discoveries come from linking ideas we thought were separate. For anyone who geeks out over numbers, that’s pretty thrilling.

New technique promises clearer, more frequent views of black holes
positiveScience
Scientists have developed a breakthrough method that could give us crisper, more frequent snapshots of black holes—think of it like upgrading from a blurry polaroid to a high-definition video. This technique doesn’t just sharpen the images; it adds color (metaphorically speaking) to show how these cosmic monsters change over time, almost like watching them "live."
Editor’s Note: Black holes are notoriously camera-shy—it took a global effort just to capture that first fuzzy image in 2019. Now, this advancement could crack open a new window into their behavior, helping us understand how they grow, interact, and warp spacetime around them. For space nerds and scientists alike, it’s like getting front-row seats to the universe’s most mysterious show.

Ketamine may treat depression by 'flattening the brain's hierarchies,' small study suggests

Ketamine may treat depression by 'flattening the brain's hierarchies,' small study suggests
positiveScience
A small but intriguing study suggests that ketamine—yes, the same substance sometimes used as a party drug—might help treat depression by "flattening" the brain's usual power structures. Normally, certain brain regions dominate communication, but ketamine seems to encourage more cross-talk between areas that usually keep to themselves. It’s a fresh angle on how the drug could reset dysfunctional brain networks in depression.
Editor’s Note: Depression treatments often hit a wall—what works for one person might do nothing for another. If ketamine really does "democratize" brain communication (as one researcher put it), it could open doors to entirely new approaches. Of course, it’s early days—this was a tiny study—but it’s a fascinating clue in the puzzle of why ketamine sometimes works when other drugs fail. For anyone tired of the trial-and-error grind of antidepressants, that’s hopeful news.
