The experiment was conducted by a multidisciplinary team from Fudan University, Beijing University of Posts and Telecommunications, Shanghai Institute of Technical Physics, and Shaoxin laboratory. The innovation lies in creating a flexible mesh of tellurium nanowires, installed over the damaged retina.

This structure acts as an autonomous phototransducer, capable of converting light into electricity without the need for external batteries. The current generated directly activates the optic nerve, allowing visual signals to reach the brain, promoting partial image perception.

Progress Registered in Tests with Rodents

During the tests, scientists implanted the artificial retina in rodents with induced blindness and monitored their reactions. The results showed that the animals reacted to light again, displaying pupillary reflexes and even recognition of visual patterns.

Night Vision and Beyond Human Perception

Another promising aspect of the technology is its ability to capture light in the near-infrared spectrum, something beyond the reach of human vision. This raises the possibility of future use to enhance vision in low-light environments.

Such functionality could be applied not only in medicine but also in security contexts, nighttime mobility, and even military operations, offering advantages beyond merely restoring vision.

The idea of an artificial retina that enhances natural visual capabilities might, in the future, alter the very concept of normal vision, going beyond sensory rehabilitation.

Strategic Advancement in the Use of Semiconductor Materials

The choice of tellurium as a key element is one of the technical highlights of the project. This semiconductor has unique photovoltaic properties and is biocompatible, making it ideal for intracorporeal medical applications.

The fact that the device works without external power sources represents a break from traditional prosthetic models, which are generally dependent on electric power and rigid structures, less compatible with ocular tissues.

According to a report published by the portal HDblog, researchers emphasize that although the tests are in the early stages and limited to animal models, the potential of the technology is undeniable and is already attracting attention from the international scientific community.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

Scientists have created a material six times lighter than air, 75 times lighter than styrofoam, and that becomes stronger the more it is compressed: aerographite seems impossible, but it can reinforce structures, batteries, and satellites.

Described by astronauts as one of the most unlikely natural phenomena on Earth, the Okavango Delta spreads over up to 15,000 square kilometers in the middle of the desert and transforms Botswana into a living labyrinth of channels, islands, and flooded areas.

Brazil is sitting on one of the largest lithium reserves in the world, in the Jequitinhonha Valley, but national mining has almost become an appendage of China: 97% of the metal’s export goes to a single country, which also dominates refining.

Petrobras is expected to complete the drilling of the Morpho well in the Foz do Amazonas in August 2026, the first well in the Equatorial Margin, an oil frontier that the ANP estimates at more than 30 billion barrels and could redraw the map of Brazil.

The Caspian Sea, the largest lake in the world, is drying up due to climate change and no one can stop the loss: evaporation could lower the level by up to 21 meters this century and turn ports in Kazakhstan, such as Aktau, into desert.

The Amaterasu particle, a cosmic ray with energy millions of times greater than that of the world’s largest accelerator, hit the Earth coming from the Local Void, a region of space that is practically empty where, in theory, there should be nothing capable of creating it.

During the construction of the world’s highest bridge, the Huajiang Bridge in China, engineers discovered a giant aquifer and turned what would have been a serious problem into a 625-meter artificial waterfall, an engineering feat that no one had planned.
