Scientists have developed an artificial photosynthesis system that essentially regulates itself, eliminating the need for batteries used in many current designs. The key innovation is an electrolyzer that automatically adapts to changing sunlight by altering its electrical properties as it heats up. This keeps solar fuel production more stable while reducing cost and complexity.
“Space computing, the final frontier, has arrived,” Nvidia CEO Jensen Huang declared at the Nvidia GTC conference in March. Indeed, the idea of data centers in orbit has gone from science fiction to a serious spending category. Elon Musk’s SpaceX has acquired xAI (also Musk’s) and is planning a constellation of space-based data centers. Google , not to be outdone, announced Project Suncatcher in…
AI summary No hay un evento único que conecte los tres artículos. El primero de Wired discute cómo políticos republicanos, inversores tecnológicos y OpenAI han vinculado el movimiento anti-centros de datos en EE. UU. con interferencia china, aunque expertos dicen que es más complejo. El segundo de IEEE Spectrum informa sobre el interés en centros de datos orbitales, con SpaceX adquiriendo xAI y planeando una constelación, y Google anunciando el Proyecto Suncatcher. El tercero de Xataka describe cómo la Generación Z tecnológica en Silicon Valley ha dejado el alcohol y ahora se enfoca en trabajar hasta 92 horas, siguiendo el ejemplo de figuras como Mark Zuckerberg, Elon Musk, Sam Altman y Bryan Johnson.

Scientists discovered that rice behaves in a highly unusual way: it weakens under rapid compression but stays stronger when pressure is applied slowly. Using this effect, they engineered a new material that reacts differently to gentle movements and sudden impacts. The material can adapt its stiffness automatically, opening the door to safer soft robots and protective equipment that responds…
NASA has selected the Artemis III crew for a high-stakes 2027 mission designed to test the future of lunar exploration. Astronauts will launch aboard Orion and perform unprecedented docking operations with lunar landers being developed by both Blue Origin and SpaceX. The mission will require a remarkable sequence of heavy-lift rocket launches and complex in-space maneuvers, helping pave the way…
AI summary A NASA selecionou a tripulação da Artemis III para uma missão complexa em 2027, que testará a exploração lunar futura. Os astronautas lançarão a bordo da Orion e realizarão operações de acoplamento com módulos lunares da Blue Origin e SpaceX. Além disso, a NASA identificou uma zona segura para a trajetória da cápsula, evitando detritos de
The new open-source project could serve as the basis for a future of apps with features as complex as Slack, Discord, or Google Docs—but with added protection against surveillance.
JWST has revealed dramatic differences between the dawn and dusk regions of the scorching exoplanet WASP-121 b. Fierce winds appear to carry heat from the planet’s permanent dayside, making the evening side hotter and more expanded. Scientists also found signs that water is being broken apart by extreme temperatures and that mysterious mineral clouds may be shaping the cooler side’s atmosphere.
The EPICS (Engineering Projects in Community Service) in IEEE program, administered by IEEE Educational Activities , has launched the Excellent EPICS in IEEE Contributor Awards . The recognitions honor the program’s outstanding students and faculty volunteers in Excellent Team Leader and Excellent Faculty Advisor categories. The awards recognize individuals whose leadership, mentorship, and…
A man raises his phone as police move into a crowd. The video is shaky, loud, immediate. Within minutes, it is online. Within hours, it is everywhere. This is how accountability works now. Something happens, someone records it, and that footage can show what really happened, sometimes contradicting official accounts. It can empower citizens and create consequences for officials. But the footage’s…
MIT researchers have shown that one fuel can power both chemical and electric spacecraft thrusters, potentially transforming what small satellites can do. The approach combines quick bursts of speed with highly efficient long-range propulsion in a single compact system. A NASA-supported CubeSat mission will soon test the technology in orbit.

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better able to retain their energy while traveling through space. This idea could help explain how these rare particles reach Earth and provide new clues about the powerful cosmic explosions that create them.
Astronomers have spent years searching for a possible hidden giant planet far beyond Neptune. Unusual orbits among distant Kuiper Belt objects have fueled the Planet Nine theory, but recent discoveries are challenging the idea by showing more stable motion than expected. If Planet Nine exists, it may be much farther away than originally thought.
NASA says a long-running air leak aboard the ISS recently worsened, leading engineers to investigate new suspected crack locations and consider a riskier repair strategy. Astronauts were temporarily moved into a safe haven as a precaution before the repair was postponed for further analysis.
New York City was the backdrop of this year’s IEEE Honors Ceremony , held on 24 April. The event celebrates engineering pioneers who have developed technologies that have changed how people connect and learn about the world. This year’s celebrants included the engineers behind innovations such as text-to-donate technology, AI-powered diagnostic tools , and the graphics processing unit, among many…
What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time challenges the popular view that the past, present, and future all exist together in a timeless "block universe." The argument suggests that physicists may be blurring the difference between things that exist and things that merely occur, creating deep confusion about what…
Scientists used nanoscale gold metamaterials to supercharge heat transfer across tiny gaps, achieving up to four times more energy flow than similar conventional systems. The breakthrough could lead to better chip cooling, more efficient energy technologies, and a new era of precision heat engineering.
Researchers have finally resolved a key problem in a 100-year-old theory of color, showing that the qualities we perceive in colors are intrinsic to the mathematics of color space itself. The discovery sharpens our understanding of human vision and could lead to more precise color technologies and visualizations.
A lightweight new X-ray telescope could finally give scientists something they’ve never had before: a complete chemical map of the Moon. Researchers used detailed mission simulations to show that a compact telescope orbiting the Moon could identify key elements across the entire lunar surface, helping reveal how the Moon formed and evolved.
