Researchers build a lightweight sound-canceling device using sub-wavelength metamaterial structures. It blocks 94% of noise but preserves air passage. It can block a wide range of noises, including intense vibrations of an MRI machine. The types...
Self-driving cars are 5% less accurate in detecting dark-skinned people. This happens because the majority of object-detection algorithms had mostly been trained on datasets containing images of white people. The machine learning models have begun...
It’s really hard to make money and maintaining a massive wealth is equally difficult. In the last couple of decades, we have seen many billionaires losing their money in a matter of months. But what exactly caused those losses? Well, most of...
Researchers use lasers to transmit sound at 60 decibels to a target person standing 2.5 meters away. They develop a method that relies on the photoacoustic effect, which takes place when a material creates sound waves after absorbing light. The...
Researchers develop a new chip-based optical instrument to securely transfer quantum information over long distances. It works by creating quantum pairs of one visible-light photon and one near-infrared photon. Unlike existing communication...
Do you know that Antarctica was once the part of Gondwana super-continent which consisted of modern-day Africa, Australia, South Africa, South America, and the Indian Subcontinent? That’s right, the Antarctica we see today is a result of a...
PDF file format is used to present and exchange documents reliably across different platforms. It can incorporate a wide range of document styles, from media-based documents to text-heavy manuals and official forms. Fortunately, there is no shortage...
Researchers injected nanoparticles in mice’s eye to make them see and respond to infrared light. The technology has minimal side effects, and could be adopted for human eyes in the near future. The human visual system is capable of detecting...
A new technique converts carbon dioxide from a gas into solid particles of carbon, using a liquid metal catalyst. It can convert the gas back into carbon at room temperatures, in an efficient and scalable manner. Negative carbon emission...
Engineers develop neural networks for self-driving cars to detect people and predict their next movements. It can accurately predict poses and next positions for multiple pedestrians simultaneously up to 45 meters from the vehicle. Most self...
Researchers create a bioreactor that enables the heart tissue to shrink in sync with electrical stimulation. They used very small pieces of heart tissue with preserved function and structure to build this device. It allows scientists to finetune...
Researchers create record-cold quantum gas of potassium-rubidium molecules at temperatures as cold as 50 nanoKelvin. The findings will help scientists compare chemical reactions in classical v/s quantum surroundings. In quantum mechanics, a system...
