In a discovery that sounds straight out of a sci-fi movie, Chinese scientists have identified a previously unknown bacterial strain aboard the
Tiangong Space Station
. Named Niallia tiangongensis, the microbe was isolated during the Shenzhou-15 mission in May 2023 and appears to thrive in conditions most life forms would find unbearable. This microbe's ability to endure extreme space stressors has amazed researchers and may hold the key to better understanding life in space. The findings raise intriguing questions about microbial resilience and offer potential applications ranging from astronaut health to waste recycling on Earth.
How the microbe survives where others fail
Life in space is no picnic. With constant radiation, microgravity, and oxidative stress, even the hardiest Earth microbes struggle to stay functional. Not so for Niallia tiangongensis. Scientists observed that this space-dwelling bacterium has heightened defenses against oxidative damage, allowing it to repair cellular harm more efficiently. This resilience suggests it has evolved or adapted mechanisms that could inform future medical and biological technologies aimed at protecting astronauts during prolonged exposure to space conditions.
A microbial first for the Chinese space station
Niallia tiangongensis marks the first unique microbial discovery from within China's Tiangong Space Station. Found inside a crew cabin, this bacterial strain adds to a growing body of knowledge about how microorganisms behave in closed, artificial environments like spacecraft. Its detection is part of the China Space Station Habitation Area Microbiome Programme (Champ), which monitors microbial life to ensure crew safety and support long-term missions.
What it means for astronaut health and spacecraft safety
While microbes in space might sound like harmless hitchhikers, they can pose real risks to both astronaut health and equipment. Bacteria can affect air quality, degrade spacecraft materials, and contaminate sensitive systems. By understanding how Niallia tiangongensis behaves and survives in space, scientists can better anticipate microbial threats, develop sterilization techniques, and design improved environmental controls for future missions. This could be crucial for long-duration flights, such as missions to Mars or lunar bases.
A microscopic tool for planetary problems
Beyond its implications for spaceflight, Niallia tiangongensis may offer valuable tools for life on Earth. The bacterium has shown potential for breaking down organic compounds, making it a candidate for sustainable waste recycling. These traits could be harnessed in agriculture, medicine, or industrial applications where controlling or utilizing microbial activity is essential. What began as a routine check on microbial levels aboard a space station might ultimately lead to more efficient, eco-friendly solutions here on Earth.
A floating lab with far-reaching potential
Tiangong continues to act as more than just a space habitat; it is now proving to be a cutting-edge laboratory for exploring biology beyond Earth. Microbes like Niallia tiangongensis demonstrate the untapped potential of space environments to inspire innovations in biotechnology, sustainability, and health. As research progresses, the knowledge gained from these tiny astronauts could have an outsized impact on how we explore space and care for our planet.

Nvidia sounds the alarm: Chinese AI talent defecting to Huawei as U.S. chip curbs push them out the door
Nvidia is sounding the alarm about the unintended impact of US export restrictions on sending chips to China, as the company's senior VP of research and chief scientist, Bill Dally, said that the chipmaker is now witnessing an increasing number of former Nvidia AI researchers joining Huawei, a move prompted primarily by the tightening export controls, as per a PC Gamer to Dally's calculation, the number of AI researchers working in China has grown from a third of the world's total in 2019 to nearly half at present, reported PC Gamer, which cited a translation from the Taiwan Economic Daily report. The AI chipmaker's rationale is that without US restrictions, Huawei wouldn't be forced to focus so much on domestic AI solutions, but now it must do so to keep up, according to the PC Gamer report. However, this is not the first time Nvidia is pointing out that the US export restrictions for China are harming the AI industry in America. Even during Computex last month, Nvidia CEO Jensen Huang said, "AI researchers are still doing AI research in China and if they don't have enough Nvidia, they will use their own [chips]," and he also spoke regarding Huawei specifically, saying the company has become "quite formidable", reported PC Gamer. While, it is not just the US national interest that has urged Nvidia to highlight all the possible negatives of export controls, as these restrictions have cost and will cost the chipmaker lots of money, according to the report. Nvidia had revealed that after billions of dollars lost due to the restrictions of its H20 chips to China in Q1, it's expecting another $8 billion to be lost for the same reason in Q2, reported PC Gamer. According to the report, Huawei's latest Ascend 910 and 920 chips, with the help of China's SMIC (Semiconductor Manufacturing International Corporation), would be a better option for Chinese AI companies than trying to get their hands on Nvidia chips, as per the report. Why is Nvidia concerned about its AI researchers joining Huawei? Because it signals that export restrictions might be pushing top talent and innovation into China, instead of slowing its progress. How much money has Nvidia lost from these restrictions? Nvidia says it lost billions in Q1 and expects another $8 billion in losses in Q2 due to blocked chip sales to China.

Sharp detection, no noise: China tests breakthrough radar technology
During the tests, the silent Cessna, using the new radar tech, identified ground targets with over 20 decibels greater clarity than traditional techniques New Delhi In a breakthrough that could reshape the future of military operations, Chinese scientists have developed a radar system that can detect moving targets without making a sound — even in the noisiest environments. The technology, developed by a team led by radar scientist Li Zhongyu, uses passive bistatic airborne radar and advanced signal processing to detect targets while remaining undetectable itself, reported South China Morning Post. The test Scientists in China tested a new type of radar technology using two small planes (Cessna-208 Caravans) flying in formation, separated by altitude. The one above sent out radar signals, and the other, flying silently below, gathered echoes without emitting any signals. They aimed to detect three vehicles moving far ahead over uneven terrain covered with dense vegetation and structures. For traditional radar systems, detection in such conditions is difficult because radar signals bounce all over the place in these environments. This creates clutter on radar screens, making it difficult to distinguish actual targets. Problems faced by traditional radar When two radar units operate separately, the reflected signals from targets don't stay aligned—they get spread out over different distances, known as range migration. This scattering causes the target's signal to blur, making it harder to detect clearly. Additionally, the Doppler effect, which helps identify moving objects, gets distorted as these frequency shifts spread over a wide range. This creates a lot of background noise that drowns out the actual signals from targets. Moreover, the unnecessary echoes change unpredictably depending on the distance, making it very difficult for conventional radar systems to filter them out effectively. How the new radar solves them The new approach uses three steps for clear detection: Motion correction: The researchers used techniques called Keystone transform and high-order compensation to gather the dispersed target signals into precise range spots. This focused energy made the targets easier to identify, aided by a process known as motion correction. Spectrum compression: This step refines blurred Doppler signals to sharpen the radar's ability to identify motion, improving target resolution. Space-time decoupling: Their breakthrough technology, called the 'space-time decoupling two-channel clutter cancellation method,' uses a special matrix (a math formula) to separate the clutter's non-linear knots. By aligning spatial frequencies to zero while preserving relative speed profiles, it allows perfect cancellation of environmental clutter between dual-channel echoes. During the tests, the silent Cessna identified ground targets with over 20 decibels greater clarity than traditional techniques, reported SCMP. The first tests for this novel tech were conducted five years ago. Military and strategic implications If and when implemented, the new radar technology could help military planes spot targets — vehicles, ships, missiles — at long range without being detected, even through clouds or darkness. Li's innovation also eliminates the exposure risks of low-probability-of-intercept (LPI) radars. LPI radars minimise the chance of being detected by operating at lower power levels or changing frequencies, but they still carry a risk of discovery. 'According to our knowledge, this is a world first,' Li claimed about the innovation.

Want even tinier chips? Use a particle accelerator
Semiconductor chips are among the smallest and most detailed objects humans can manufacture. Shrinking the scale and upping the complexity is a fight against the limits of physics, and optical lithography—etching nanometre-scale patterns onto silicon with short-wavelength light—is its most extreme frontier. ASML , a Dutch firm that builds such lithography tools, takes an almost sci-fi approach by blasting molten tin droplets with lasers in a vacuum to produce extreme ultraviolet (EUV) light with a wavelength of just 13.5nm. Now, some researchers hope to generate more powerful EUV beams with a particle accelerator that propels electrons to nearly the speed of light. The need for this radical proposal stems from a fundamental limitation of current EUV sources: they struggle to generate enough power to reliably etch circuits onto silicon. In a lithography tool such as ASML's, the EUV beam bounces off nearly a dozen mirrors before it hits the silicon. EUV light is so easily absorbed, though, that even in a vacuum-sealed chamber with ultra-specialised mirrors, each reflection saps 30% of the light's energy. By the time the photons reach the wafer, less than 2% of the original EUV energy remains. Without enough power, reliability and precision plummet. One way to boost energy is to bombard the wafer with multiple doses of EUV light, a trick that slows down the chip-manufacturing process. The other approach is to increase the power of the photons. ASML's latest rig uses a light source that operates at 500 watts, nearly twice the power of its previous machines. To speed up production or to shrink feature sizes even further, the light source must get stronger. ASML currently has a road map to develop a one kilowatt light source. A more radical solution is to use a free-electron laser (FEL), where electrons travelling near the speed of light are manipulated to emit EUV radiation. The FEL process begins with a powerful electron gun that injects a beam of the particles into a miniature racetrack. The electrons then pass through a linear accelerator, which propels them to nearly the speed of light. Once accelerated, they enter a roughly 200-metre-long structure called an undulator, where a series of magnets generate a field whose polarity flips periodically. This wiggles the electrons, causing them to emit a beam of EUV photons with a specific wavelength. Nicholas Kelez, the boss of xLight, a Silicon Valley startup developing FEL-based lithography, described the technology as a more powerful and tuneable 'new light bulb" that he believes can be swapped into existing optical lithography machines. xLight expects to deliver the first commercial system within four years. Another research group, at the High Energy Accelerator Research Organisation (KEK) in Japan, has already demonstrated the ability to generate light at 20 micrometres (millionths of a metre)—far longer than the 13.5nm wavelengths ASML is capable of but a step towards refining the process. Chinese researchers are also exploring FEL technology in their quest to develop an independent EUV machine. Generating light using a FEL has some advantages over using lasers. The first is power: a lithography machine based on a FEL-based light source can be around six times more energy-efficient than a laser-plasma tool. Dispensing with molten-tin droplets also reduces the risk of contamination. Tuning such a machine for smaller wavelengths is also, at least theoretically, much easier: all that needs doing is tweaking the settings on the electron gun and the undulator. It would also be cheaper. A single FEL system can be repurposed to provide light for multiple lithography machines, allowing its operator to distribute the fixed costs across multiple chip-etching tools. Nakamura Norio from KEK estimates that the construction cost is around half that of a laser-based EUV tool and the running costs are around a fifteenth. For now, all this is theoretical. Whereas ASML's EUV machines are proving themselves in high-volume manufacturing, FEL-based lithography is still in the experimental phase. But in the high-stakes world of chipmaking, any edge is worth chasing. Curious about the world?
