Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision goggles, the contact lenses, described in the journal Cell, do not require a power source—and they enable the wearer to perceive multiple infrared wavelengths. Because they’re transparent, users can see both infrared and visible light simultaneously, though infrared vision was enhanced when participants had their eyes closed.
“Our research opens up the potential for noninvasive wearable devices to give people super-vision,” says senior author Tian Xue, a neuroscientist at the University of Science and Technology of China. “There are many potential applications right away for this material. For example, flickering infrared light could be used to transmit information in security, rescue, encryption or anti-counterfeiting settings.”
The contact lens technology uses nanoparticles that absorb infrared light and convert it into wavelengths that are visible to mammalian eyes (e.g., electromagnetic radiation in the 400–700 nm range). The nanoparticles specifically enable the detection of “near-infrared light,” which is infrared light in the 800‑1600 nm range, just beyond what humans can already see.
Venus Aerospace had the first-ever U.S. flight test of a rotating detonation rocket engine (RDRE)—a next-gen propulsion technology that’s been theorized for decades, but never flown… until now. The Rotating Detonation Rocket Engine (RDRE) changes everything, and Venus is the first venture-backed aerospace company to bring the RDRE from concept to commercialization. RDREs are a breakthrough technology for rocket propulsion, which have the potential to offer several benefits over traditional rocket engines.
New 3D printing technique makes it possible to heal injuries and damaged tissues from inside without surgery.
Lassi Rautiainen is a Finnish photographer who captured photographs of a unique friendship between a female grey wolf and a male brown bear. The two buddies were seen every night for ten consecutive days. They spend a few hours together between 8. p.m. and 4. a.m. The wolf and the bear even share food with one another.
Apparently, it is very rare to observe a wolf and a bear getting along this well. It is unsure as to how and why the two creatures became friends in the first place. Lassi assumes that the wolf and the bear felt lonely and weren’t very sure as to how to survive on their own. They were also young so they must have found it nice to share the rare events that occur in the wild.
Lassi was glad to have come across these two friends because it made the perfect story. He felt as if the wolf and the bear found it safe being together. “No one had observed bears and wolves living near each other and becoming friends in Europe” he expressed. This unlikeliest of friendships is sure to inspire us all.
Researchers have made a discovery that could make quantum computing more compact, potentially shrinking essential components 1,000 times while also requiring less equipment. The research is published in Nature Photonics.
A class of quantum computers being developed now relies on light particles, or photons, created in pairs linked or “entangled” in quantum physics parlance. One way to produce these photons is to shine a laser on millimeter-thick crystals and use optical equipment to ensure the photons become linked. A drawback to this approach is that it is too big to integrate into a computer chip.
Now, Nanyang Technological University, Singapore (NTU Singapore) scientists have found a way to address this approach’s problem by producing linked pairs of photons using much thinner materials that are just 1.2 micrometers thick, or about 80 times thinner than a strand of hair. And they did so without needing additional optical gear to maintain the link between the photon pairs, making the overall set-up simpler.
Scientists want to study the way your body’s gut microbes react and interact with psychedelic substances like magic mushrooms.
Underestimating one’s own cognitive abilities is common in depression and PTSD. A new study finds that cognitive training—especially through engaging games—may help people recalibrate their self-perceptions and feel better.
Ringworld, by sci-fi author Larry Niven is based on hypothetical megastructures in space called Dyson Spheres but, says Niven, “I took just the equator… the poor man’s Dyson sphere!”

Scientists have discovered that senescent sensory neurons accumulate with age and nerve injury, releasing inflammatory molecules that heighten pain sensitivity. The findings suggest that targeting these dysfunctional cells could reduce chronic pain, particularly in older adults.
