Elon Musk’s Neuralink achieved a significant milestone last week in its pursuit to restore vision to those who have lost it. The neurotechnology company, founded by Musk, announced on X (formerly Twitter) that it had been granted “Breakthrough Device Designation from the FDA” for its innovative Blindsight device.

Musk described the Blindsight device as capable of allowing even individuals who have lost both their eyes and optic nerves to regain sight. “As long as the visual cortex is intact, the device will even enable those who have been blind since birth to see for the first time,” Musk wrote on X. Initially, the vision provided by Blindsight will be low-resolution, Musk noted, comparing it to “Atari graphics.” However, he highlighted its potential to improve dramatically over time. While this isn’t the first time Musk has suggested that Blindsight might exceed normal vision, some experts remain skeptical. Research from the University of Washington cautioned that without significant technological breakthroughs, the vision provided by Blindsight and similar devices is likely to remain limited and imperfect.

Earlier this year, Neuralink made headlines after successfully implanting a brain chip into Noland Arbaugh, a paralyzed man. Following the procedure, Arbaugh was able to control computers and play online games using only his mind.

The FDA’s Breakthrough Devices Program aims to expedite the development and approval process for devices that offer more effective treatment or diagnosis of life-threatening or irreversibly debilitating conditions.

People with hearing loss often face the “cocktail party problem,” where it’s hard to focus on one voice in a noisy environment. OrCam Technologies’ OrCam Hear aims to solve this with a system of earbuds and an AI-powered app.
The app samples voices, creates speaker profiles, and allows users to isolate a specific voice, muting others. “Deep networks and advanced language models are used to significantly improve hearing aids and hearables,” said Amnon Shashua, OrCam’s co-founder, in a press release.

The company plans to begin production of the device later this year.

“Starry Night” is widely regarded as one of the most famous paintings in the world, second only to the Mona Lisa. But what many admirers might not realize is that van Gogh’s swirling sky is not just visually striking—it’s also “alive with real-world physics.”

The brushstrokes in Starry Night create such a convincing illusion of atmospheric motion that scientists specializing in fluid dynamics in China and France became curious about how closely it mirrors the actual physics of the sky. Because you can’t measure actual motion in the painting itself, the scientists used van Gogh’s brushstrokes as a proxy for real atmospheric movement. By analyzing the scale and spacing of these swirling strokes, they found that van Gogh’s portrayal of the sky “accurately captures” energy cascading in turbulent flows—a phenomenon they call “hidden turbulence.”

According to Dr. Huang Yongxiang, one of the study’s authors, the size of the brush strokes was key. “By using high-resolution digital images, we were able to precisely measure the size of the strokes and compare them to turbulence theories.” The researchers likened the swirling brushstrokes to leaves caught in a whirlwind, which allowed them to analyze the shape, energy, and scaling of atmospheric characteristics in the painting. They also used the varying brightness of the paint as a stand-in for the kinetic energy of movement in the sky.

“It reveals a deep and intuitive understanding of natural phenomena,” Dr. Huang explained. “Van Gogh’s precise representation of turbulence might be from studying the movement of clouds and the atmosphere or an innate sense of how to capture the dynamism of the sky.” The study, published in Physics of Fluids, examined the 14 main swirling shapes in Starry Night and found they aligned with Kolmogorov’s law, a theory that describes how kinetic energy is transferred in turbulent flows from large to small scales.

On a finer level, the team found the brightness diffused in the brushstrokes also followed Batchelor’s scaling, which explains energy transfer in smaller, passive atmospheric turbulence. Finding both types of energy scaling in one system is rare, and it was a major motivation for their research.

For years, Easter Island (Rapa Nui) has been cited as a cautionary tale of ecological collapse. Known for its giant stone heads, or moai, the island’s population was thought to have dwindled due to overuse of natural resources, leading to societal breakdown. However, a new genetic study published in Nature debunks this long-held theory.

Led by an international team of scientists from the University of Copenhagen, the study found no evidence of a dramatic population collapse before European contact in 1722. “Our analysis shows a stable population from the 13th century through the 18th century, contradicting the idea of a pre-contact collapse,” said Víctor Moreno-Mayar, assistant professor of geogenetics at Copenhagen. The researchers analyzed genomes from 15 Rapanui individuals who lived between 1670 and 1950, finding no signs of a reduced gene pool that would indicate a population crash. The collapse theory argued that the islanders depleted their resources, particularly trees, to build and transport the moai, eventually leading to famine, violence, and even cannibalism. But genetic evidence now suggests that the Rapanui adapted to environmental challenges over centuries, maintaining societal stability until disrupted by European contact. Previous studies had questioned the collapse theory based on archaeological and population dynamics data, but this is the first time genetics has been used to address the issue.

Researchers now believe that while the island’s landscape did change between the 13th and 18th centuries, the Rapanui people were resilient and resourceful. “The population stability shows they adapted to the environmental challenges they faced,” said Bárbara Sousa da Mota from the University of Lausanne, co-author of the study. Moreno-Mayar further argued that the idea of ecological suicide was part of a colonial narrative, casting the islanders as unable to manage their resources, a claim refuted by the genetic findings.

German company Paxos Solar has introduced a new glass photovoltaic roof tile that can reduce energy demand by up to 20% when connected to a heat pump. This year, the company aims to install the tiles on 200 roofs.

For homeowners looking for a cleaner energy solution without the bulky setup of traditional photovoltaic panels, these solar roof tiles offer a space-efficient alternative. They blend in seamlessly with a roof’s appearance and don’t require extra space. While many companies provide solar roof tiles, Paxos has taken an innovative approach by integrating them with heat pumps. In collaboration with TH Köln University of Applied Sciences, Paxos spent two years developing a prototype that generates both electricity and heat. The team tested various factors like temperature, optical loss, environmental conditions, and safety. Their findings showed that the heat pump’s performance improved by nearly 25%, depending on weather and heating needs.

Now, Paxos has partnered with Longi to mass-produce these tiles. Each tile measures 23.45 x 18.89 inches and delivers 44 watts of power, with five tiles generating up to 190 watts in just 10 square feet of roof space. Paxos intentionally designed these tiles larger than competitors’ models to allow faster installation and higher power output. The tiles are installed using a support rail system above a water-bearing layer. Air flows under the tiles, and when the air heats up, it is collected and funneled into the heat pump, further boosting efficiency. A study by the University of Cologne found that homes using these solar tiles required 20% less energy for heating over a year.

Paxos also claims that their solar tiles are lighter and take half the time to install compared to traditional roofing methods.
