Fusion energy has remained an elusive goal for decades. While nuclear fission is widely used in power plants, fusion—the process that powers the Sun—has proven far more difficult to harness. However, a new breakthrough involving the Small Aspect Ratio Tokamak (SMART) could bring us significantly closer to achieving practical nuclear fusion.

Developed by the University of Seville’s Plasma Science and Fusion Technology Laboratory, SMART recently achieved its first plasma, marking an important milestone in fusion research. Unlike conventional tokamaks, SMART explores the concept of negative triangularity, a unique plasma configuration that could solve one of the biggest hurdles in fusion energy: plasma stability.

𝑻𝒐𝒌𝒂𝒎𝒂𝒌𝒔: 𝑨 𝑪𝒓𝒖𝒄𝒊𝒂𝒍 𝑺𝒕𝒆𝒑 𝑻𝒐𝒘𝒂𝒓𝒅𝒔 𝑬𝒏𝒆𝒓𝒈𝒚 𝑰𝒏𝒅𝒆𝒑𝒆𝒏𝒅𝒆𝒏𝒄𝒆

Tokamaks are donut-shaped reactors designed to contain and stabilize super-heated plasma using powerful magnetic fields. The challenge with these devices has always been controlling instabilities that can disrupt fusion reactions.

Traditionally, plasma in tokamaks has a positive triangularity—meaning the “D”-shaped plasma has its curved edge facing outward. However, scientists have discovered that flipping this configuration to negative triangularity can suppress dangerous instabilities such as Edge Localized Modes (ELMs). These instabilities can damage reactor walls and make sustained fusion reactions difficult.

SMART is the first compact tokamak specifically designed to test negative triangularity on a practical level. If successful, this approach could significantly improve plasma confinement and make fusion energy more viable and cost-effective.

SMART is more than just a scientific experiment; it is a core component of the Fusion2Grid strategy at the University of Seville. This initiative aims to develop grid-based fusion energy as a practical alternative to fossil fuels.

The success of SMART could help design compact, high-performance fusion reactors that are both affordable and scalable. Unlike massive fusion projects such as ITER, SMART’s compact nature allows for faster development cycles and lower costs.

Lunar Surfaces: Evidence of Recent Geological Activity on the Moon

The Moon was previously thought to be geologically inactive, but new research suggests that it still experiences tectonic activity. Recent studies reveal small ridges on the lunar surface, formed in the last 200 million years, indicating ongoing geological processes. Understanding these features is crucial for future lunar exploration and potential astronaut missions.

𝐒𝐮𝐦𝐦𝐚𝐫𝐲

The Moon likely formed from a giant impact between Earth and a Mars-sized object called Theia.
Evidence from Apollo missions and seismic studies suggests the Moon once had a magnetic field and volcanic activity.
The Moon’s volcanic activity was thought to have ended about 3 billion years ago, making it geologically dead.
A recent study by the National Air and Space Museum (NASM) and the University of Maryland (UMD) challenges this view.
Researchers found small ridges on the Moon’s far side that are younger than those on the near side.
These ridges likely formed in the last 200 million years due to ongoing tectonic forces.
A technique called crater counting helped determine the ridges’ age.
The ridges may have been caused by moonquakes, which result from shifts in the Moon’s orbit and gradual shrinkage.
Apollo missions first detected moonquakes, but their significance has only recently been understood.
New discoveries suggest the Moon remains geologically active, affecting future lunar missions.
Future missions should use ground-penetrating radar to study subsurface structures.
Scientists aim to determine how these ridges formed and if tectonic activity is still occurring.
Findings impact plans for Moon bases, affecting astronaut safety and infrastructure placement.
Understanding lunar geology helps in designing equipment for long-term Moon exploration.
The research was published in the Planetary Science Journal, with contributions from multiple institutions.

𝐆𝐢𝐚𝐧𝐭 𝐈𝐦𝐩𝐚𝐜𝐭 𝐇𝐲𝐩𝐨𝐭𝐡𝐞𝐬𝐢𝐬 𝐚𝐧𝐝 𝐌𝐨𝐨𝐧’𝐬 𝐅𝐨𝐫𝐦𝐚𝐭𝐢𝐨𝐧

The Giant Impact Hypothesis suggests that the Moon formed around 4.5 billion years ago from debris after a massive collision between Earth and a Mars-sized object, Theia. This theory is supported by Apollo mission rock samples, which show similarities between Earth and Moon compositions. Seismic studies further confirm their shared history.

𝐋𝐮𝐧𝐚𝐫 𝐒𝐮𝐫𝐟𝐚𝐜𝐞 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬 𝐚𝐧𝐝 𝐕𝐨𝐥𝐜𝐚𝐧𝐢𝐬𝐦

Early observations suggested that the lunar maria—dark, flat regions on the Moon—formed due to volcanic activity billions of years ago. Scientists believed the Moon’s volcanic activity ended around 3 billion years ago, leaving it geologically inactive.

𝐍𝐞𝐰 𝐄𝐯𝐢𝐝𝐞𝐧𝐜𝐞 𝐨𝐟 𝐑𝐞𝐜𝐞𝐧𝐭 𝐀𝐜𝐭𝐢𝐯𝐢𝐭𝐲

A study by NASM and UMD found small ridges on the Moon’s far side that are younger than previously thought. These ridges, formed within the last 200 million years, suggest that the Moon is still tectonically active.

According to lead researcher Cole Nypaver, these ridges align in groups of 10 to 40, possibly formed over weak spots in the lunar crust. Using crater counting, scientists estimated their age and concluded that some ridges formed in the last 160 million years.

By Jonathan Bala January 30, 2025

Organic Molecules in Asteroid Bennu Samples: Clues to Life’s Origins Uncovered

NASA’s OSIRIS-REx mission successfully returned a sample from asteroid Bennu, revealing organic molecules that are essential for life. The analysis showed the presence of all five nitrogen bases required for DNA and RNA, as well as 14 amino acids, formaldehyde, ammonia, and other prebiotic materials. These findings support the panspermia theory, which suggests that asteroids may have delivered the building blocks of life to Earth. The discovery of minerals formed in water-rich environments also hints at the past existence of liquid water on Bennu.

𝑺𝒖𝒎𝒎𝒂𝒓𝒚 𝒐𝒇 𝑭𝒊𝒏𝒅𝒊𝒏𝒈𝒔

NASA’s OSIRIS-REx mission collected 121.6 grams of material from asteroid Bennu.
The samples contained all five nitrogen bases crucial for DNA and RNA.
Scientists detected 14 amino acids, essential for protein formation in living organisms.
Bennu’s samples also included ammonia, formaldehyde, and N-heterocycles.
Minerals such as calcite, halite, and sylvite indicate the presence of water in Bennu’s past.
The presence of vitamin B3 (nicotinic acid) supports the theory that asteroids provided nutrients for early Earth life.
The results were published in Nature and Nature Astronomy.

𝑵𝑨𝑺𝑨’𝒔 𝑶𝑺𝑰𝑹𝑰𝑺-𝑹𝑬𝑿 𝑴𝒊𝒔𝒔𝒊𝒐𝒏

The OSIRIS-REx mission, launched by NASA in 2016, aimed to study asteroid Bennu and return samples to Earth. The spacecraft reached Bennu on December 3, 2018, mapping the asteroid in detail before collecting a sample in October 2020.

The returned samples were carefully stored and analyzed at NASA’s Goddard Space Flight Center and the Johnson Space Center. The mission’s success has expanded our understanding of early Solar System chemistry.

𝑩𝒖𝒊𝒍𝒅𝒊𝒏𝒈 𝑩𝒍𝒐𝒄𝒌𝒔 𝒐𝒇 𝑳𝒊𝒇𝒆 𝑶𝒏 𝑩𝒆𝒏𝒏𝒖

A major discovery in the Bennu sample was the presence of all five nitrogenous bases used in DNA and RNA: adenine, cytosine, guanine, thymine, and uracil. These are the core components that store genetic information in all life forms on Earth.

Additionally, researchers from Hokkaido University and JAMSTEC found high concentrations of N-heterocycles, which are organic compounds important for biological activity.

“The clues we’re looking for are so minuscule and so easily destroyed or altered from exposure to Earth’s environment. That’s why some of these new discoveries would not be possible without a sample-return mission.”
— Daniel P. Glavin, NASA Goddard Space Flight Center

𝑻𝒉𝒆 𝑹𝒐𝒍𝒆 𝒐𝒇 𝑾𝒂𝒕𝒆𝒓 𝑰𝒏 𝑨𝒔𝒕𝒆𝒓𝒐𝒊𝒅 𝑪𝒉𝒆𝒎𝒊𝒔𝒕𝒓𝒚

Scientists also found 11 types of minerals formed in water-rich environments, including calcite, halite, and sylvite. The Natural History Museum in London confirmed that these minerals could only form in briny water, suggesting that Bennu once had liquid water.

This discovery is important because similar brine chemistry has been observed on Ceres, Enceladus, and Europa, raising the possibility of habitable environments beyond Earth.

𝑪𝒐𝒎𝒑𝒂𝒓𝒊𝒏𝒈 𝑩𝒆𝒏𝒏𝒖 𝒂𝒏𝒅 𝑹𝒚𝒖𝒈𝒖

Scientists compared the Bennu sample with materials from asteroid Ryugu, collected by JAXA’s Hayabusa2 mission.

Feature	Bennu Sample	Ryugu Sample
Amino Acids	14 types detected	Less abundant
Nucleobases	All 5 nitrogen bases	Only uracil and vitamin B3
Water-formed Minerals	High presence	Lower presence
Organic Complexity	More diverse molecules	Less complex compounds

These findings suggest Bennu may have originated in a colder, more water-rich environment than Ryugu.

𝑾𝒉𝒂𝒕’𝒔 𝑵𝒆𝒙𝒕 𝒇𝒐𝒓 𝑨𝒔𝒕𝒆𝒓𝒐𝒊𝒅 𝑺𝒂𝒎𝒑𝒍𝒆 𝑺𝒕𝒖𝒅𝒊𝒆𝒔?

The Bennu samples will continue to be studied for decades, with international collaborations involving NASA, Hokkaido University, and CRESST. Scientists hope to decode the full chemical history of Bennu and confirm whether similar asteroids contributed to life’s emergence on Earth.

The discoveries made by the OSIRIS-REx mission are significant not only for understanding the origins of life on Earth but also for the potential existence of life elsewhere in the Solar System. The building blocks of life—amino acids, nucleobases, and complex organic molecules—have been found on Bennu, supporting the idea that asteroids could have played a critical role in life’s development. As Jason P. Dworkin, one of the researchers on the mission, pointed out:

Scientists are still trying to understand why life developed on Earth and not on other planets. However, findings from Bennu give us important clues. These findings suggest that the Solar System might support life more than we previously believed. The successful mission to Bennu helps us move closer to solving a big mystery in science. This mystery is about how life started and if it can exist outside Earth.

Introduction: A New Frontier in Quantum Physics

For decades, electrons have fascinated physicists because of their dual nature as particles and waves. However, scientists have only now succeeded in measuring the shape of an electron’s wave function as it moves through a solid. This quantum geometry, measured by a team at MIT led by Riccardo Comin, provides a new way to understand and control the behavior of electrons in materials.

Their research, published in Nature Physics, uses Angle-Resolved Photoemission Spectroscopy (ARPES) to observe how light interacts with electrons. By doing so, the team unraveled the mysterious geometric properties of electrons within kagome metals, a special class of materials with unique lattice structures.

Quantum Geometry: A Key to Advanced Materials

The study of electrons typically revolves around energy or velocity. However, the geometry of electron wave functions provides a new layer of information. This shape determines how electrons interact, pair up, and flow through materials without resistance.

The quantum geometry of electrons plays a critical role in phenomena like superconductivity, where electrical currents move through a material without losing energy. It also helps explain why electrons sometimes form orderly patterns, much like dancers in synchronization.

“We’ve essentially developed a blueprint for obtaining some completely new information that couldn’t be obtained before.” – Riccardo Comin

Understanding quantum geometry could enable scientists to design materials with customized properties, unlocking possibilities in fields like quantum computing and advanced electronics manufacturing.

Table 1: Key Concepts in Quantum Geometry

Concept	Definition	Relevance
Quantum Geometry	The shape or patterns of electron wave functions in a material	Impacts electron behavior and interactions
Superconductivity	A phenomenon where electrons flow without resistance	Used in energy-efficient systems
Kagome Metals	Materials with a triangular atomic lattice structure	Enables unique electronic properties
Angle-Resolved Photoemission Spectroscopy (ARPES)	A technique to measure electron angles and spins in materials using light	Key method for observing quantum geometry

Kagome Metals and Quantum Behavior

The breakthrough discovery was made using kagome metals, named after their atomic lattice that resembles interlocking triangles. This structure allows electrons to display unique properties, such as advanced superconductivity and unusual alignment behaviors.

In kagome metals, the triangular lattice influences how electrons move and interact, making it an ideal material for exploring quantum geometry. The lattice can even give rise to exotic states of matter, such as topological phases, where electrons behave in ways not observed in ordinary materials.

Using ARPES, researchers measured how electrons within kagome metals interact with light, revealing their wave function shapes for the first time.

How ARPES Works

ARPES is an advanced technique where a beam of photons shines on a material, ejecting electrons. Scientists then analyze the angles and spins of these electrons, allowing them to reconstruct how electrons move inside the material.

Although ARPES requires specialized equipment and precise conditions, it provides a detailed view of electron behavior on scales smaller than a billionth of an inch.

This technique was crucial in uncovering the quantum geometry of electrons, confirming long-held theoretical predictions about their wave functions.

Table 2: How ARPES Helps in Electron Studies

Feature	Purpose	Outcome
Photon Beam	Shines light on material to eject electrons	Reveals electron movement
Angle Measurement	Determines angles at which electrons are ejected	Helps reconstruct quantum geometry
Spin Analysis	Measures electron spin states	Provides insights into magnetic properties
Wave Function Mapping	Observes quantum shapes inside materials	Confirms theoretical predictions about electrons

Applications and Future Potential

The ability to measure electron wave function shapes has far-reaching implications. Quantum computing, for example, relies on maintaining stable electronic states while performing computations. By designing materials with specific quantum geometries, researchers can create devices that minimize energy loss and improve stability.

Another promising application lies in superconductors, where electrons flow without resistance. This property could lead to more efficient power grids, faster computers, and advanced magnetic levitation systems.

Quantum sensors, memory devices, and energy-efficient electronics are just some of the potential innovations that could benefit from a deeper understanding of quantum geometry.

Collaborative Efforts and Global Impact

This discovery would not have been possible without the collaboration of institutions across the globe. Researchers from Cornell University and MIT combined their theoretical and experimental expertise to design, synthesize, and measure the electronic structure of kagome metals.

Despite challenges like the pandemic, the team demonstrated the importance of integrating theory and experiment in high-precision measurements. Their work provides a foundation for future research into quantum materials.

Facts About Quantum Geometry

Quantum geometry isn’t limited to electrons. It also applies to photons and phonons (quantized vibrations in materials).
The term “kagome” originates from a Japanese basket-weaving pattern with triangular motifs.
ARPES experiments are so precise they can measure distances smaller than the width of a single atom.

Future Directions in Research

Building on this breakthrough, scientists aim to refine ARPES techniques and explore a wider range of materials. Future studies may investigate how quantum geometry influences magnetism, conductivity, and electron pairing.

By manipulating quantum shapes, researchers hope to encourage electrons to synchronize and cooperate. This could lead to advancements in technologies that rely on controlling multiple electrons simultaneously, such as quantum sensors and memory elements.
