Announced on October 24, this new version allows users to put on the suit directly from their wheelchairs without needing help from others.

The WalkON Suit series, under development since 2015, targets individuals with the most severe form of paralysis, classified as ASIA Impairment Scale – A (complete paralysis). Unlike other rehabilitation and strength-assisting robots in use, the WalkON Suit F1 is designed specifically to aid independent mobility for people with paraplegia.

A California-based company, SpinLaunch, is turning heads with its groundbreaking satellite launch system, capturing the imagination of space enthusiasts and even Punkin Chunkin fans. SpinLaunch’s innovative approach uses a massive rotating arm to hurl satellites into low Earth orbit, eliminating the need for traditional rocket fuel and relying solely on electricity.

The company has already achieved multiple successful test launches. “This is not a rocket, and clearly our ability to perform this many tests within 11 months, all functioning as planned, really showcases the power of our technology,” said Jonathan Yaney, founder and CEO of SpinLaunch, in a 2022 interview with Space.com after the company’s 10th successful test launch. SpinLaunch aims to deploy satellite constellations into orbits below 600 miles by 2026.

Researchers from University College London (UCL) have shattered the world record for wireless transmission speed, marking a significant step toward faster, more reliable wireless communication. The UCL team successfully transmitted data over the air at an astonishing speed of 938 Gigabits per second (Gb/s) across a frequency range of 5-150 Gigahertz (GHz). This speed is nearly 9,380 times faster than the current average 5G download speed in the UK, which stands at around 100 Megabits per second (Mb/s). The breakthrough comes with a total bandwidth of 145GHz, more than five times the previous world record.

Currently, wireless networks transmit data using a narrow range of radio frequencies, typically below 6GHz. This has led to congestion and limited the speed of wireless communication technologies such as Wi-Fi and 5G. The UCL team, however, overcame this bottleneck by utilizing a much wider range of frequencies, combining both radio and optical technologies for the first time.

As artificial intelligence drives exponential growth in data demand, nuclear power is emerging as a key player in revolutionizing energy supply for data centers. Tech giants like Oracle and Microsoft, alongside influential figures such as Bill Gates, have begun exploring nuclear energy solutions. In a notable move, Microsoft has secured an agreement to purchase power from the Three Mile Island reactor, signaling a shift toward clean, reliable energy sources for its data operations.

One of the most promising developments in this field is the advent of micro nuclear reactors. These compact reactors offer a safe, sustainable, and efficient way to meet the growing energy needs of data centers and other industries. Companies like Nano Nuclear Energy are making strides in this area, aiming to deliver commercial microreactors by the early 2030s, with prototypes expected as soon as 2027.

In a groundbreaking yet concerning development for global cybersecurity, Chinese researchers have demonstrated how quantum computing could accelerate the downfall of current encryption methods. Using D-Wave’s quantum annealing systems, the researchers have successfully cracked classic encryption techniques, potentially fast-tracking the timeline for when quantum computers could undermine the cryptographic systems that protect sensitive information worldwide.

The research, published in the Chinese Journal of Computers under the title “Quantum Annealing Public Key Cryptographic Attack Algorithm Based on D-Wave Advantage,” highlights how D-Wave’s quantum machines were able to break RSA encryption and launch attacks on symmetric encryption algorithms. These findings pose serious questions about the future of cybersecurity.

Water has always been a source of life, but now, it’s set to power cars, reshaping the future of clean energy. While hydrogen has long been hailed as the primary clean fuel for the automotive sector, recent developments suggest that water-based fuel might take the lead. The introduction of the first water-powered car has sparked discussions among experts, with some even suggesting that this breakthrough could mark “the end of hydrogen” as the go-to clean fuel.

Electriq Global, an Australian-Israeli company, has developed a revolutionary fuel that is 60% water-based. Using innovative technology, Electriq extracts hydrogen from water and uses it to power vehicles, offering a cheap, clean, and safe fuel alternative. The potential impact on global energy consumption and the automotive industry is immense.

Scientists have developed a groundbreaking method to split seawater into hydrogen fuel using electrodes, eliminating the production of harmful and corrosive chlorine gas that typically results from such processes. This innovative approach, spearheaded by California-based startup Equatic, in collaboration with ARPA-E, promises to generate clean hydrogen fuel without requiring pure water—making it a major step forward in sustainable energy.

Traditionally, hydrogen fuel is produced via electrolysis, a process in which water is split into hydrogen and oxygen using an electrolyzer. However, using seawater has been problematic due to the corrosive minerals and salts it contains. When seawater is subjected to electrolysis, these salts are separated, leading to the production of toxic chlorine gas, which corrodes the machine’s internal components and gums up its operations.

Fungi are remarkable lifeforms that challenge conventional ideas of intelligence. Despite lacking brains, these organisms exhibit signs of decision-making and communication. But just how complex are they, and what insights can they provide into other forms of awareness? A team of researchers from Japan’s Tohoku University and Nagaoka College sought to explore these questions through an intriguing experiment on the cord-forming fungus Phanerochaete velutina. Their study, published in Fungal Ecology, reveals that fungi can “recognize” different spatial environments and adjust their growth strategies accordingly.

While fungi are often recognized by their aboveground mushrooms, these are merely the surface manifestation of a vast underground network known as mycelium. These intricate webs stretch for miles beneath the soil, capable of transmitting environmental information throughout the network. Yet, the growth of mycelium doesn’t appear random—it seems to follow a deliberate, calculated pattern.

Quantum physics often challenges our understanding of reality, and a new study led by Daniela Angulo from the University of Toronto adds another mind-bending discovery to the mix: photons, the wave-particles of light, can seem to pass through a cloud of atoms in “negative” time, effectively appearing to exit a material before they even enter it.

Aephraim Steinberg, a physicist from the same university, shared this surprising result on X (formerly Twitter), after the team’s findings were uploaded to arXiv.org in early September. While not yet peer-reviewed, the study reveals that photons interacting with a cloud of ultracold rubidium atoms can appear to spend a negative amount of time in the excited state—a phenomenon that defies conventional expectations.

For nearly a century, dark matter—a mysterious substance believed to account for most of the universe’s mass—has baffled scientists. First hypothesized by Dutch astronomer Jan Oort in 1932 to explain the unseen mass necessary for galaxies to remain intact, dark matter has remained elusive, with no direct detection despite decades of research. However, a recent study by Dr. Richard Lieu of The University of Alabama in Huntsville (UAH) proposes a groundbreaking alternative that could shift our understanding of cosmic forces.

In his paper, published in the Monthly Notices of the Royal Astronomical Society, Dr. Lieu introduces a revolutionary theory suggesting that gravity might exist without the presence of mass. If correct, this theory could explain certain gravitational phenomena without the need for dark matter.

When is an empty tube not just an empty tube? When it’s a ramjet utilizing cutting-edge rotating detonation technology to propel aircraft at hypersonic speeds. This is precisely the innovation behind Venus Aerospace’s new engine—the Venus Detonation Ramjet 2000 lb Thrust Engine (VDR2).

Hypersonic flight, defined by speeds exceeding Mach 5, faces significant challenges, especially in designing engines capable of sustained thrust. While current hypersonic systems primarily rely on glide bodies that are boosted to extreme altitudes by rockets, achieving consistent, high-speed flight requires something more akin to a jet engine. Venus Aerospace’s VDR2 seeks to bridge this gap.

South Korea has made history by becoming the first nation to deploy a laser weapons system, known as the “Star Wars Project” or officially, “Block-I.” This innovative defense system, developed by Hanwha Aerospace, was unveiled by the Defense Acquisition Program Administration (DAPA) as part of a broader strategy to neutralize threats, including North Korean drones. With plans to expand its capabilities to space, this marks a new era in unmanned weapons systems.

In July 2024, DAPA confirmed the mass production of the Star Wars laser system, aimed at defending South Korea from North Korean drone incursions. The laser system fires invisible and silent beams, relying solely on electricity and requiring no ammunition. Each shot costs approximately $1.45 (2,000 won), making it a highly economical option compared to traditional weapons. Using fiber optic cables, the system generates laser beams of about 700°C (1292°F), powerful enough to melt drones and disable their engines.
