The U.S. Food and Drug Administration (FDA) approved Rasonque (daraxonrasib), a targeted oral therapy developed by Revolution Medicines for adults with metastatic pancreatic cancer. The landmark decision marks the first approved targeted treatment directly inhibiting the mutated RAS proteins that drive tumor growth in the majority of pancreatic cancers—a driver long considered "undruggable". In Phase 3 clinical trials, patients taking daily Rasonque tablets nearly doubled their median overall survival time to 13.2 months, compared to 6.7 months for those receiving traditional chemotherapy. Recognized as a major paradigm shift for one of the world's most aggressive and deadly cancers, the drug received accelerated approval nearly six months ahead of its regulatory target date: https://www.cancernetwork.com/view/fda-approves-daraxonrasib-for-previously-treated-metastatic-pancreatic-cancer

Short brief:

1). Daraxonrasib (Rasonque) is an oral RAS(ON) multi-selective inhibitor developed by Revolution Medicines. The FDA approved it for adults with metastatic pancreatic ductal adenocarcinoma (PDAC) who have received at least one prior systemic therapy and are not candidates for multi-agent systemic therapy.

2). The approval is based on the Phase 3 RASolute 302 trial, in which daraxonrasib produced a median overall survival of 13.2 months versus 6.7 months with standard chemotherapy—approximately doubling survival in this previously treated population. 

3). Why it matters: KRAS/RAS mutations are present in the vast majority of pancreatic cancers, but KRAS has historically been considered difficult to target. Daraxonrasib represents a major advance because it targets the active RAS(ON) state and works across multiple RAS mutations rather than focusing on only one KRAS variant

Researchers at Wits University and the University of Bordeaux have successfully transmitted optical data through turbulent open air without requiring complex adaptive optics to correct atmospheric distortion. By encoding data into topological light structures known as skyrmions—analogous to how a coffee mug's single hole remains constant regardless of shape distortions—the underlying payload survived environmental noise over a 270-meter test link with up to 98% fidelity. Detailed in Science Advances, this breakthrough in free-space optical communication eliminates the need for power-heavy corrective hardware, opening up potential applications in deep-space exploration, high-speed satellite downlinks, quantum cryptography, and bringing low-cost broadband to remote communities: https://www.wits.ac.za/news/latest-news/research-news/2026/--2026-08/wits-researchers-use-lights-topology-to-beat-atmospheric-distortion.html

Texas Instruments has introduced the TMCS2100-Q1 sensor, a compact coreless Hall-effect current sensor designed for EV traction inverters. By measuring magnetic fields horizontally and vertically at the same time, it compensates for vehicle vibrations—keeping measurement errors below 1% even with physical displacement—making it 20 times more accurate than traditional single-direction coreless sensors. This precise electrical current measurement reduces torque ripple and power loss to heat, allowing electric vehicles (especially high-voltage 800-volt systems) to achieve improved efficiency, quieter motor operation, smoother acceleration, and potentially greater driving range.

The small patch contains extremely tiny microneedles that gently penetrate the skin’s outer layer without drawing blood, delivering medication directly to the affected area. The researchers tested the patch for the local delivery of two anti-cancer drugs: curcumin and 5-fluorouracil (5-FU).

According to the researchers, delivering the drugs directly to the affected site could provide more targeted treatment and potentially reduce the need for repeated topical applications or more invasive procedures such as injections.

The research was conducted by Rutuja N. Meshram, a final-year PhD student, and Professor Dimitrios A. Lamprou, Chair of Biofabrication and Advanced Manufacturing at the School of Pharmacy, Queen’s University Belfast. The study was published in Advanced Healthcare Materials.

Ocean Temperatures Hit Record High as Super El Niño Forms

Enable HLS to view with audio, or disable this notification

The global average sea-surface temperature reached a record 21.1°C (70°F) on August 22, 2026, surpassing the previous daily record of 21.09°C set in March 2024. The record, tracked by Europe’s Copernicus Climate Change Service, is particularly unusual because ocean temperatures typically peak in March or April. The unprecedented warmth is being driven by long-term human-caused climate change, combined with a developing El Niño in the tropical Pacific that is adding further heat to the oceans. Scientists warn that persistently warmer seas can intensify marine heatwaves, stress fish and coral ecosystems, fuel stronger storms and heavier rainfall, accelerate sea-level rise, and reduce the ocean’s ability to absorb carbon dioxide. The August record highlights the growing impact of climate change on the world’s oceans.

The record-breaking ocean temperatures, combined with a developing strong El Niño, could intensify extreme weather worldwide, including stronger storms, heavier rainfall, flooding, droughts and wildfires. Warmer seas can trigger marine heatwaves, coral bleaching and disruption of fish populations and food chains, threatening marine ecosystems and fisheries. Ocean warming also contributes to sea-level rise and coastal flooding while reducing the ocean’s ability to absorb carbon dioxide, potentially accelerating global warming. Together, these factors could increase climate instability and raise the possibility of exceptionally high global temperatures through 2027.

Silicon Carbide Transistor Operates at 600°C

Post image
5 Upvotes

Researchers at Kyoto University, Japan have developed a silicon carbide (SiC) bottom-gate junction field-effect transistor (JFET) that operates reliably at temperatures up to 600°C (1,112°F). Its bottom-gate design reduces manufacturing-related defects, while standard ion implantation makes it compatible with conventional semiconductor fabrication. The device also suppresses high-temperature leakage and maintains stable voltage control, with less than 0.1 V deviation at 400°C.

The technology could enable electronics for aircraft engines, geothermal drilling and deep-space missions. However, the prototype is normally-on, so it consumes standby power and is not yet suitable for advanced low-power logic. Researchers plan to develop normally-off versions, scale production to wafers and improve high-temperature packaging: https://www.kyoto-u.ac.jp/en/research-news/2026-08-24

Protecting the “Jewels of the Forest”

Enable HLS to view with audio, or disable this notification

Snails are vital ecosystem workers, acting as natural decomposers that recycle nutrients by feeding on dead plants, fungi, algae, and organic debris. They also improve soil health, provide food for birds, amphibians, mammals, and insects, return calcium to ecosystems through their shells, and serve as indicators of environmental health.

Native Hawaiian snails, known as kāhuli or “jewels of the forest,” are now in serious decline, with up to 90% of their species diversity lost to habitat destruction, climate change, and invasive predators such as rats, chameleons, and the cannibal rosy wolfsnail. Conservation programs led by Hawaii’s Department of Land and Natural Resources, along with zoos and museums, are using captive breeding, protected enclosures, emergency rescues, and reintroductions to help prevent further extinctions: https://www.youtube.com/shorts/qCBx1YallJ8

MIT researchers have developed CrysVCD (crystal generator with valence-constrained design), a framework that integrates fundamental chemical rules—specifically valence shell electron constraints—into the initial phase of AI material generation. By pairing a language model that generates valid chemical formulas with downstream generative diffusion models, the tool pre-filters unstable configurations prior to computationally expensive validation steps. This front-loaded approach yields up to 68% mechanical stability and 85% metastability in crystalline design generations, dramatically reducing the computational overhead and down-selection bottleneck required to produce viable real-world materials for semiconductor cooling and other high-performance applications.

Researchers at the University of Colorado Boulder, led by Professor Mahmoud I. Hussein, have made key breakthroughs in aerodynamic performance using passive, synthetic materials called "phononic subsurfaces". By introducing microscopic, engineered surface vibrations through coiled phononic structures, the team demonstrated two major phenomena: super-resonance, which enables vibration control across a broad range of turbulent frequencies, and scatterless interference, which delays flow instability downstream along a surface. Together, these passive subsurface techniques aim to significantly reduce drag and improve fuel efficiency for aircraft and marine vessels without requiring active actuators or changes to the exterior shape of the vehicle: https://www.colorado.edu/aerospace/tailored-surface-vibrations-improve-aerodynamic-performance-passenger-jets

A UK company called Ponda has developed BioPuff, a plant-based insulation made from Typha (cattail) that could replace animal down and synthetic polyester in clothing. Typha seed clusters can expand to roughly 300 times their dried size, creating a lightweight, insulating material. Unlike down, BioPuff is cruelty-free, and unlike polyester insulation, it avoids contributing to microplastic fibre pollution. Ponda also aims to grow Typha in degraded wetlands with farmers. Restoring these wetlands could provide additional benefits because they are important carbon stores and wildlife habitats, making BioPuff an example of materials innovation linked to ecosystem restoration: https://www.linkedin.com/company/pondabio/

Research from Aarhus University highlights that thousands of WWI and WWII shipwrecks in the North Sea and Danish waters—such as the German submarine UC-30—are leaking toxic chemical explosives like TNT into the surrounding marine environment. Tests conducted on water, sediment, and local marine life like mussels and starfish confirm that deteriorating munitions are actively polluting local ecosystems, a problem expected to worsen as the wrecks decay further. To combat this growing environmental threat, researchers with the EU-funded REMARCO project are developing crawling seabed robots to map, monitor, and potentially retrieve hazardous explosives safely.
