Latest Advancements In Technology

ID a species in seconds—No DNA test required A scientific technique best known for measuring blood oxygen levels and testing food quality is now proving to be a game changer for conservation biology. Researchers in Brazil are using near-infrared (NIR) spectroscopy to identify species in the field—quickly, accurately, and without the need for costly lab work or genetic testing. In the Mamirauá Sustainable Development Reserve in the Brazilian Amazon, scientists like Kelly Torralvo are using handheld NIR scanners to detect unique “spectral signatures” in amphibians and reptiles, reports Miguel Monteiro. “The NIR tool is an advance in laboratory and field activities,” she says. “It can facilitate processes in countless activities related to academic studies, monitoring, inspections, and conservation actions.” Initial trials have yielded an 80% identification accuracy, with some species correctly recognized in over 90% of cases. The approach works even with salted or frozen game meat, offering a powerful tool against illegal wildlife trade. Experts are optimistic. “With a calibrated database, all you have to do is pass the light beam through it and, voilà: the species is recognized,” says ecologist Pedro Pequeno. Compact, practical, and scalable, the technology may transform biodiversity monitoring in some of the world’s most complex ecosystems. 📰 https://lnkd.in/g2nyg_NT

Researchers at Hong Kong University MaRS Lab have just published another jaw dropping paper featuring their safety-assured high-speed aerial robot path planning system dubbed "SUPER". With a single MID360 lidar sensor they repeatedly achieved autonomous one-shot navigation at speeds exceeding 20m/s in obstacle rich environments. Since it only requires a single lidar these vehicles can be built with a small footprint and navigate completely independent of light, GPS and radio link. This is not just #SLAM on a #drone, in fact the SUPER system continuously computes two trajectories in each re-planning cycle—a high-speed exploratory trajectory and a conservative backup trajectory. The exploratory trajectory is designed to maximize speed by considering both known free spaces and unknown areas, allowing the drone to fly aggressively and efficiently toward its goal. In contrast, the backup trajectory is entirely confined within the known free spaces identified by the point-cloud map, ensuring that if unforeseen obstacles are encountered or if the system’s perception becomes uncertain, the system can safely switch to a precomputed, collision-free path. The direct use of LIDAR point clouds for mapping eliminates the need for time-consuming occupancy grid updates and complex data fusion algorithms. Combined with an efficient dual-trajectory planning framework, this leads to significant reductions in computation time—often an order of magnitude faster than comparable SLAM-based systems—allowing the MAV to operate at higher speeds without sacrificing safety. This two-pronged planning strategy is particularly innovative because it directly addresses the classic speed-safety trade-off in autonomous navigation. By planning an exploratory trajectory that pushes the speed envelope and a backup trajectory that guarantees safety, SUPER can achieve high-speed flight (demonstrated speeds exceeding 20 meters per second) without compromising on collision avoidance. If you've been tracking the progress of autonomy in aerial robotics and matching it to the winning strategies emerging in Ukraine, it's clear we're likely to experience another ChatGPT moment in this domain, very soon. #LiDAR scanners will continue to get smaller and cheaper, solid state VSCEL based sensors are rapidly improving and it is conceivable that vehicles with this capability can be built and deployed with a bill of materials below $1000.

It says something about the British press when you need to look to the French to celebrate achievements in the UK 🤣 The technological breakthrough celebrated by Média 24 last week occurred in Oxfordshire! It turns out, while we’ve been doom-scrolling about energy bills, the team at Tokamak Energy just quietly achieved a world first with their "Demo4" system. They have successfully built a complete system of HTS (High Temperature Superconducting) magnets in a real reactor configuration. The stats are mind-blowing: 🧲 It generated a magnetic field of 11.8 Teslas (about 4x stronger than a hospital MRI). ❄️ It operated at -243°C (which, in the quantum world, is actually "hot" compared to absolute zero). ⚡ It handled 7 million amp-turns of current in its central column. Why does this actually matter? Fusion is the holy grail. It’s clean, it’s safe, and unlike fission, there is no long-lived waste. But controlling plasma at 100 million degrees requires magnets that don't melt or consume all the energy they produce. Tokamak just proved their magnets can do it. Even better? These magnets are 200x more efficient than copper. That tech isn't just for fusion; we’re talking about future applications in zero-loss power grids, electric aircraft, and next-gen MRI machines. My take: I’ve been vocal about the need for SMRs (Small Modular Reactors) to bridge our energy gap. Fission is here, it works, and we need it. But Fusion is the endgame. It is one of the several areas where the UK punches way above its weight. It is refreshing to be reminded that despite the headlines, British engineering is still quietly leading the world. Have you seen any other "good news" stories that the UK media seems to have missed lately? #NuclearFusion #TokamakEnergy #UKTech #CleanEnergy #Innovation

Using a water-based hydrogel as a scaffold, researchers at EPFL (École Polytechnique Fédérale de Lausanne) created complex structures that can be infused with metal salts. After several rounds of soaking and heating, the gel vanishes – leaving behind dense, ultra-strong metal or ceramic. Traditional metal 3D printing often results in porous structures with serious shrinkage. This new method dramatically reduces those flaws, producing durable, precisely shaped components with only 20% shrinkage. It also opens the door to building with a wide range of materials – the same gel template can be used to grow iron, silver, copper, or even advanced composites. The technique could revolutionize how we make complex, high-performance parts for energy systems, biomedical devices, and next-gen electronics. It’s also a shift in mindset: rather than designing around the limits of printing materials, this approach lets researchers build first, and choose the material later. The team is already working on automating the process, aiming to bring this breakthrough into real-world manufacturing.

Japan’s bullet train once had a sound problem. Every time it exited a tunnel, it created a loud boom. The issue was air pressure. As the train entered a tunnel at high speed, it pushed compressed air ahead of it. When that pressure wave came out from the other side, it created a sudden explosive sound. The solution came from nature. Engineer Eiji Nakatsu, who loved bird watching, studied how the kingfisher dives into water at high speed with almost no splash. That observation inspired the JR West team to redesign the 500 Series Shinkansen’s nose into a longer, sharper, beak like shape. The new design allowed air pressure to build more gradually when the train entered tunnels. There was another sound problem too. The pantograph, the part that connects the train to overhead electric wires, created aerodynamic noise. For that, the team looked at owl wings and used serration like shapes to reduce sound. The result was a train that was quieter, faster, and more energy efficient. Sometimes innovation begins by observing the world more carefully. #innovation #technology

Canada builds noise-cleaning highways that erase traffic sound Along several Canadian highways, engineers have installed a new type of sound barrier that doesn’t just block noise — it absorbs and neutralizes it. The system uses porous mineral foam layered with micro-cavities that draw in sound waves and dissolve them through controlled vibration transfer. Instead of reflecting noise back into neighborhoods, the material essentially “swallows” traffic noise. The panels were first tested on a quiet stretch outside Vancouver, where residents noticed an immediate difference. Car engines, braking, and tire friction dropped to nearly silent levels when passing the barrier. Microphones placed behind the wall showed up to a 92% noise reduction, far beyond traditional concrete or metal sound barriers. This level of quiet reshaped the environment for both people and wildlife. Urban planners believe these noise-cleaning barriers could dramatically improve life quality in dense areas. Children’s sleep patterns, school performance, and general stress levels often suffer near highways. With this new technology, Canadian suburbs could experience nighttime quiet even with major roads nearby. Birds and small mammals may also return to habitats once disturbed by constant mechanical noise. The mineral foam is highly recyclable, weather-resistant, and stable across temperature extremes. Engineers designed the panels to be repaired easily and replaced section-by-section, making large-scale deployment affordable. Several provinces have already committed to introducing the barriers near hospitals, parks, and residential complexes. Canada’s innovation shows that revolutionizing infrastructure doesn’t always require cutting-edge electronics — sometimes, the quietest solutions are built from simple materials reshaped with precision. #engineering

THIS!! A paper that marks the culmination of many months of careful, sustained work by my PhD student, Elizabeth Wall. It began with a deceptively simple question:🙋🏻♀️ Why do fabrication recipes for one of the most promising next-generation solar cell technologies vary so widely?🤨 Perovskite solar cells have advanced rapidly in efficiency. Yet across the literature, reports on the role of the processing environment remain inconsistent — even contradictory. Some report moisture as catastrophic. Others argue it is essential for perovskite crystallisation. Still others suggest humidity must be precisely “just right.” Even within our own group at Princeton CBE, device performance appeared to vary seasonally. Winter☃️ cells behaved differently from summer👙cells. We suspected the processing environment was a key factor. What we lacked was a clear understanding of what mattered, when, and why.⁉️🤷🏻♀️ This is where Liz stepped in and took the lead.💪🏻 To systematically isolate environmental variables during fabrication, Liz designed atmosphere-controlled setups,🎛️ retrofitted a glovebox to switch cleanly between nitrogen and air, and tightly controlled humidity at each deposition and annealing step in a two-step FAPbI₃ fabrication process, where precursors are introduced sequentially. With those controls in place, clear correlations emerged between processing atmosphere, precursor phases, film structure, and morphology. Device performance became markedly more consistent and reproducible.👍🏻 To probe the underlying mechanisms, Liz then carried out in situ X-ray scattering experiments at the National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory,⚡️tracking how precursor structures evolved during film formation under different atmospheric conditions. One result stood out.👇🏻 While device performance showed limited sensitivity to humidity across most processing steps, operational stability did not. Fully dry-processed devices — as well as those with a humid final anneal — consistently exhibited substantially improved stability under illumination.💡 Published in Advanced Energy Materials: https://lnkd.in/eG2MeYQM This work removes a key barrier to translating laboratory demonstrations into scalable, reliable technologies. I am immensely proud of Liz for seeing this study through.🤩 And Quinn Burlingame for being a sounding board and mentor to Liz. Thank you also Moungi Bawendi and Yu-Kuan Lin at Massachusetts Institute of Technology for the high-quality passivation layers and for testing some of our devices.🫶🏻 I am compelled to mention that this work was supported by the U.S. Department of Energy (DOE). The very support that was withdrawn several months ago.☹️ The science stands. The students continue to move forward. Whether work like this continues at scale depends on whether sustained public investment in fundamental energy research remains a priority.☝🏻 Photo of Liz beaming at the beam line. 😁

Japan’s first flying car is officially ready for the market: ⤵ But calling it a flying car is misleading. This is an eVTOL: An electric aircraft that takes off and lands vertically using multiple electric rotors. It is not replacing your car. It is creating a new transportation layer above crowded cities. 1/ ➠ What this technology actually is ➝ eVTOLs combine electric propulsion, vertical takeoff, and automated flight systems. ↳ Launch from compact vertiports. ↳ No runway required. ↳ Quieter than helicopters. ↳ Multiple motors improve redundancy. Ideal for dense cities where space is limited. 2/ ➠ What market entry really means ➝ This does not mean everyone will own one. ↳ Early use will likely be premium air taxis. ↳ Airport transfers first. ↳ Business routes next. ↳ Mass adoption later. The first customers are buying time, not a new lifestyle. 3/ ➠ Cities need new infrastructure ➝ Aircraft alone cannot scale. They also need: ↳ Vertiports. ↳ Charging systems. ↳ Air traffic management. ↳ Maintenance and safety systems. This creates opportunities across software, batteries, property, insurance, and operations. 4/ ➠ Transportation becomes three-dimensional ➝ eVTOLs add a new layer above roads. Potential benefits: ↳ Faster emergency response. ↳ Better access to remote areas. ↳ New delivery options. But they also raise questions around noise, affordability, privacy, and airspace management. 5/ ➠ The real product is trust ➝ Technology alone will not drive adoption. People need confidence that it is: ↳ Safe. ↳ Reliable. ↳ Affordable. ↳ Well regulated. The aircraft may be ready. The bigger question is whether cities and the public are ready for them. ▶ Would you use one? ▶ What would earn your trust? ▶ Who is responsible when automation fails? ▶ Will this reduce congestion or simply create traffic in the sky? ▶ What happens when thousands of aircraft compete for space above dense cities? // Repost this ⇄ // Sources: https://lnkd.in/dBgqQJZ6 https://lnkd.in/dWQ-r8Zc https://lnkd.in/duzqgZuD // Follow me for daily posts on emerging tech and growth: Jeremy Prasetyo

The audit firm that used to send 6 people for 5 weeks now sends 2 for 2 weeks. Not (just) because they're more efficient. Because your GRC platform already did the testing. This is the Zillow effect in compliance. Platforms shifted from passive storage to active control testing. They now collect evidence, test controls, and form opinions on effectiveness. The auditor validates the platform's opinion instead of forming their own from scratch. This is what we discuss in this week's entry of the GRC Engineer newsletter! → Platforms now collect evidence automatically → Test controls based on their logic → Form opinions on effectiveness → Present auditors with pre-assessed landscape The auditor validates platform opinions instead of forming their own from scratch. This created: → Information parity (you see what auditors see in real-time) → Audit fees dropping 60-90% (discovery work already done) → New business model: checkbox audits at £15k (just trust platform, sign report) → Power inversion (platform choice matters more than auditor choice) But here's the problem most miss: Your platform is now your compliance brain. It decides control effectiveness using vendor methodology. If that logic is wrong, everyone trusts the wrong assessment. Quality auditors question platform logic. Checkbox auditors trust it. Full breakdown in this week's newsletter (link in comments). Huge shoutout to Tines for being the lead sponsor of this week's entry #GRCEngineering
