Efforts to use artificial intelligence in analysing whisky aromas have yielded promising results, as researchers demonstrated the technology’s ability to identify key notes and origins of whiskies. The study, conducted by the Fraunhofer Institute for Process Engineering and Packaging in Germany, explored the molecular makeup of 16 US and Scottish whiskies, including brands such as Jack Daniel’s, Maker’s Mark, Laphroaig, and Talisker. According to reports, the findings indicated that AI systems could provide consistency and precision in determining whisky aromas, surpassing human expert panels in certain aspects.

Study Details and Methodology

The research, published in Communications Chemistry, involved training algorithms using chemical compositions and aroma profiles provided by an 11-member expert panel. The AI was tasked with predicting the five most prominent aroma notes and distinguishing between US and Scottish whiskies. It reportedly achieved over 90 percent accuracy in identifying the origins of the whiskies, although this figure is expected to decrease when applied to untrained samples.

Dr Andreas Grasskamp, the study’s lead researcher, highlighted the AI’s consistent performance, stating to The Guardian that it serves to complement, rather than replace, human assessments. The analysis pinpointed compounds such as menthol and citronellol in US whiskies, known for their caramel-like notes, and methyl decanoate and heptanoic acid in Scottish whiskies, associated with smoky and medicinal aromas.

Applications and Expert Insights

The research is expected to have broader applications beyond whisky analysis. Reports have suggested that the technology could aid in detecting counterfeit products and managing odours in recycled plastics. Dr William Peveler, a senior lecturer at the University of Glasgow, noted to The Guardian that such approaches could offer stability in maintaining consistent flavour profiles across whisky batches.

While the study demonstrated potential, limitations remain, such as the small sample size and the challenges posed by flavour changes during aging. Experts believe further work is necessary to account for environmental and sensory factors influencing whisky perception.

May 2024 Solar Storm Triggers Unusual Radiation Belts

A significant solar storm that occurred in May 2024 led to the formation of two temporary radiation belts around Earth, as confirmed by satellite data. The discovery was made when a dormant satellite resumed operations after months of inactivity. The storm, which was among the most intense geomagnetic disturbances since 1989, resulted in widespread auroral displays and introduced high-energy particles into the Earth’s magnetosphere. While such temporary belts have been documented before, scientists have found that one of the newly formed belts exhibited unique properties, with a composition different from previous observations. One of the belts has already dissipated, but the other remains intact, posing potential challenges for future space missions.

Temporary Radiation Belts Detected Following Intense Solar Activity

According to research published in the Journal of Geophysical Research: Space Physics, the Colorado Inner Radiation Belt Experiment (CIRBE) satellite identified the new radiation belts upon reactivation in June 2024. The spacecraft had gone silent due to a technical issue in April, missing the peak of the storm. Upon its return, data analysis revealed the existence of two additional belts situated between the pre-existing Van Allen radiation belts.

It was determined that while the first belt contained high-energy electrons, consistent with previous storm-induced radiation belts, the second belt displayed an unusual concentration of high-energy protons. This presence of protons was linked to the extreme nature of the solar storm, which had released significant bursts of charged particles into Earth’s magnetic field.

Extended Lifespan of the Newly Formed Belts

Temporary radiation belts generated by solar storms are known to persist for weeks before dispersing. However, as per the findings, the electron-dominated belt remained for three months, while the proton-rich belt is still present. David Sibeck, a heliophysicist at NASA’s Goddard Space Flight Center, stated in an interview with Space.com that these particles could stay trapped for an extended period, creating a lasting impact on Earth’s inner radiation environment.

The proton belt’s resilience is attributed to its location in a more stable region of Earth’s magnetic field, where external disturbances have less impact. In contrast, a subsequent solar storm in June 2024 caused a reduction in the electron belt, with further weakening observed in August. Despite this, the proton belt has remained largely unaffected.

Implications for Space Missions and Satellite Operations

The existence of these new radiation belts has raised concerns regarding the safety of satellites and crewed space missions. Charged particles at high energy levels can pose risks to electronic components and human health in space. Spacecraft passing through these regions, particularly those traveling to geostationary orbit or beyond, may require additional shielding to mitigate radiation exposure.

As reported, the presence of these belts could necessitate adjustments in launch plans for future missions. With prolonged radiation hazards, space agencies may need to factor in the evolving space weather conditions before deploying satellites or sending astronauts beyond Earth’s orbit.

Despite the CIRBE satellite’s crucial discovery, the same solar activity that led to the identification of the new radiation belts also caused the spacecraft’s eventual demise. The increased energy injected into the atmosphere resulted in greater drag, which led to CIRBE’s descent and disintegration in October 2024.

The impact of solar storms on Earth’s magnetosphere continues to be closely monitored, with scientists studying how these phenomena affect both planetary and technological systems.

Global Rocket Launches Reach Record High in 2024

A significant increase in global rocket launches was observed in 2024, with 259 recorded liftoffs. This marked the fourth consecutive year of growth in spaceflight activity, with launch attempts occurring approximately every 34 hours. Multiple factors contributed to this rise, including increased commercial satellite deployments, national security initiatives, and a growing emphasis on independent launch capabilities across several nations. Industry experts predict an even busier year ahead as new rockets and commercial projects enter service.

Increased Launch Frequency and Regional Contributions

According to The Space Report, a publication by the Space Foundation, the expansion of global launch operations is expected to continue in 2025. The report highlighted a strong performance by SpaceX, which conducted 132 Falcon 9 launches last year, making up over half of global launches. A significant portion of these missions supported the expansion of the company’s Starlink network, which now serves millions of customers worldwide.

As reported by space.com, military satellite deployments also saw a notable surge, with an 86 percent increase recorded. SpaceX launched over 100 satellites for the U.S. military’s Starshield constellation, a classified network aimed at enhancing national security. The U.S. remained the dominant force in space launches, surpassing China’s activity by a ratio of more than 2-to-1. Meanwhile, Russia significantly increased its satellite deployments, with 98 new spacecraft placed in orbit, many focused on maritime monitoring and security operations.

New Rockets and Commercial Expansion in 2025

Multiple new rockets are set to enter service this year, further accelerating launch rates. Blue Origin’s New Glenn successfully reached orbit last month, positioning itself as a competitor to SpaceX’s Falcon 9. The vehicle is expected to play a key role in Amazon’s Project Kuiper, which aims to establish a satellite internet network similar to Starlink.

Sierra Space is preparing for the first flight of its Dream Chaser spaceplane, expected to reach the International Space Station aboard a Vulcan rocket no earlier than May. Rocket Lab’s partially reusable Neutron rocket is scheduled for its first flight in mid-2025.

Regulatory Developments and European Launch Initiatives

The Federal Communications Commission has introduced a streamlined regulatory framework to accelerate commercial space activities. Additional spectrum allocation and revised licensing procedures are expected to ease restrictions on private sector launches.

European nations are also making progress in independent launch capabilities. French company Latitude is set to launch its Zephyr rocket, while Germany’s Rocket Factory Augsburg is working on its RFA One rocket. The U.K.’s Orbex and Scotland-based Skyrora are both advancing their respective small launch vehicle projects, with maiden flights anticipated later this year.

In Australia, Gilmour Space is preparing for the inaugural flight of its Eris rocket, marking the first locally built launch vehicle to operate from Australian soil. Industry experts emphasise that these developments reflect a broader trend of countries striving for sovereign access to space through smaller, dedicated launch vehicles.

MIT Develops Tiny Robotic Insect Drones with 100x Longer Flight Time Than Before

A new generation of robotic insects has been developed with the ability to fly significantly longer than previous models. Researchers have created a design that enhances endurance, agility, and structural efficiency, allowing these robotic insects to support artificial pollination on a much larger scale. The advancement is expected to improve agricultural yields while reducing environmental impact. The technology addresses key limitations of earlier prototypes, particularly flight duration and efficiency, making them more viable for real-world applications. The robots have been engineered to store sufficient power while maintaining a lightweight structure.

Flight Capabilities Enhanced Through Structural Adjustments

According to the study published in Science Robotics, the new robotic insects have been designed to fly up to 100 times longer than their predecessors. Previous versions struggled with lift and stability due to excessive wing numbers and inefficient motion. The updated design features a structure with four units, each equipped with a single flapping wing, allowing for more controlled flight dynamics. By reducing the number of wings, excess energy consumption has been minimised, improving the robot’s overall performance.

Kevin Chen, Associate Professor of Robotics at MIT, stated to Live Science that the flight demonstrated in the research surpasses the total flight time accumulated by previous robotic insect models. It was noted that the updated wing design has reduced stress on the flexures, contributing to longer endurance. The improved structure has also enabled space for power sources, making the robotic insects more practical for field applications.

Challenges in Mimicking Natural Flight Mechanisms

Researchers highlighted that previous designs included eight wings per device, which limited efficiency due to excessive airflow resistance. It was observed that real insects rely on finely controlled wing movements, whereas the initial robotic versions lacked this level of precision. Efforts are being made to replicate the muscle-like movements of insect wings by refining signal transmissions to the robotic structure.

Future Developments in Artificial Pollination

The team aims to further refine the robotic insects by integrating sensors and computational elements to enhance autonomous functionality. It was stated that achieving a balance between weight and battery capacity remains a challenge. Over the next five years, efforts will be directed toward improving navigation and control systems, ensuring these robotic insects can operate effectively in agricultural settings.
