Brad Smith, rendered mute by amyotrophic lateral sclerosis (ALS), is speaking again—this time through a coin-sized brain implant. Surgeons embedded Neuralink’s experimental N1 “Link” device, equipped with 1,024 electrodes, directly into his motor cortex. The device translates his thoughts into movement, allowing him to steer a digital cursor and trigger AI-generated speech—entirely with his mind.

Smith is the first person with ALS, and only the third human overall, to receive the device. His message, “I am typing this with my brain,” was shared publicly in a tweet from Elon Musk, who confirmed Smith’s role in Neuralink’s initial human trial. “It is my primary communication,” Smith added.

For centuries, the steel industry has been powered by coal-driven blast furnaces—an energy-intensive and environmentally harmful process. Traditional steelmaking involves crushing iron ore, heating it to extreme temperatures, and mixing it with coke (a refined coal product), all while taking several hours to complete. But now, researchers have uncovered a groundbreaking method that slashes production time from hours to mere seconds, significantly reducing both energy consumption and pollution.

Instead of relying on coal-based reactions, the new process uses ultra-fine iron ore powder, injected into a high-temperature furnace through a specialized vortex lance. This innovative approach triggers a rapid chemical reaction, producing molten iron in just a few seconds.

Tardigrades, also known as water bears, are some of the smallest and most resilient organisms on Earth. Despite their microscopic size, these incredible creatures possess a unique set of abilities that have fascinated scientists for years. Tardigrades can survive extreme dehydration, freezing temperatures, radiation, and even the vacuum of outer space. Their remarkable resilience has led researchers to ask a bold question: Could the secret to halting aging lie within these tiny creatures?

Tardigrades have earned their reputation as “nature’s toughest animal” due to their extraordinary survival tactics. They can endure conditions that would be fatal to most other life forms, such as freezing cold, extreme heat, and lethal doses of radiation. What sets them apart is their ability to slow down their metabolism and enter a state called biostasis, essentially putting themselves in a form of suspended animation until environmental conditions improve.

An amateur researcher and former Nvidia employee, Luke Durant, has uncovered the world’s largest known prime number: 2**136,279,841 – 1, surpassing the previous record-holder (2**82,589,933 – 1) by over 16 million digits.

Prime numbers, indivisible by any other number except 1 and themselves, are considered the “atoms of integers” in mathematics, with smaller examples being 2, 3, 5, and 7. Though primes extend to infinity, finding them becomes increasingly complex as the numbers grow larger. Durant’s discovery was made using the Great Internet Mersenne Prime Search (GIMPS), a free software program designed specifically for identifying large prime numbers. The search for this new prime involved thousands of GPUs operating across 24 data centers in 17 countries—a setup that marks a new era in prime discovery, as past large primes were found primarily with personal computers.

A promising alternative to traditional plastic may have emerged, bringing hope in the battle against plastic pollution. Researchers have unveiled newly developed “bioplastic” pellets, offering a sustainable option that could surpass the environmental impact of current plastic materials used in bottles and various objects.

Published in RCS Sustainability, a recent paper sheds light on the potential of these pellets, which serve a dual purpose. Not only do they function as absorbents, effectively extracting phosphate from water—a critical step in addressing global water security concerns—but they also hold promise as agricultural fertilizer, providing a sustainable solution to nutrient depletion in soil.

Evaporation, the ubiquitous process of water transforming into vapor, has long been attributed solely to heat. However, groundbreaking research from MIT reveals a previously overlooked factor: light. In a series of meticulous experiments, scientists have demonstrated that light striking the interface between air and water can trigger evaporation independently of heat.

Published in the Proceedings of the National Academy of Sciences, the study by Professor Gang Chen and his team unveils a phenomenon dubbed the “photomolecular effect.” This effect, observed when light interacts with water molecules at the surface, leads to their liberation into the air, challenging the conventional understanding of evaporation.

A groundbreaking collaboration spearheaded by Professor John Spencer from the University of East Anglia and Assistant Professor Samuel Forbes from the esteemed Psychology Department has uncovered a pivotal connection, affecting infants as young as six months old. This correlation links the physical stature of infants to their cognitive abilities, intricately tied to brain function. The joint effort, which also involved the University of Nottingham, the Community Empowerment Lab, University of Iowa, Rhode Island Hospital, Brown University, and the Bill & Melinda Gates Foundation, represents a significant stride forward in comprehending early childhood development.

Central to this research is the concept of ‘visual working memory,’ a fundamental aspect of our cognitive framework responsible for maintaining and processing visual information. The study meticulously compared this cognitive capacity in infants experiencing stunted growth—a telltale sign of undernutrition and adverse environmental conditions—with their peers exhibiting expected growth patterns. The study’s findings are striking, revealing that infants with stunted growth display disrupted visual working memory, rendering them more susceptible to distractions. This poses a worrying precedent for their cognitive development, indicating a potentially diminished trajectory in the year ahead.
