Astronomers discovered 83 previously unknown quasars powered by supermassive black holes. These quasars are approximately 13 billion light-years away from Earth. The observations revealed that in every cubic giga-light-year there exists a...
Physicists build a new circuit that can detect very tiny quantum steps (photons) in radio frequency signals. This new quantum circuits could have a number of applications, from nuclear magnetic resonance imaging to radio astronomy. Detection of...
The new machine learning-based perception framework can recognize over 90 different objects by touch. It uses both visual and tactile observations to identify whether these observations correspond to the same object. Humans are good at associating...
For graphene-like materials, 1+1 doesn’t make 2. When such atomically thin materials are stacked on top of each other their properties change drastically. This yields a new material with novel hybrid characteristics. The study provides an...
Physicists have successfully created a quantum state that moves in the opposite direction of the thermodynamic arrow of time. They have demonstrated this state in 2- and 3-qubit quantum computer. It could be used to make quantum computers more...
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...
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...
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...
