The Chinese space administration (CNSA) is neither the oldest nor the biggest space agency in the world but it’s about to achieve a feat that has been accomplished only by few in the past; establishing a fully functional global navigation satellite system or GNSS. A GNSS is simply a satellite navig

The new machine learning tool predicts how long a given computer chip takes to execute specific code.  It is more accurate than Intel’s own prediction model.  Determining the number of clock cycles a processor takes to execute a block of assembly instructions in steady-state is crucial for both p

The space-based quantum internet would substantially outperform ground-based networks of quantum repeaters.  Building a global-scale quantum internet would require placing more than 400 satellites at an altitude of 1,900 miles.  The most useful application of quantum mechanics is the ability to p

Scientists break the world record for the fastest spinning object.  The new object revolves at 300 billion revolutions per minute.  It is made of a dumbbell-shaped silica nanoparticle powered by lasers.  Torque sensors enabled the first determination of the gravitational constant and the discover

Researchers at Facebook AI develop a new reinforcement learning algorithm named DD-PPO.  It can navigate through complex environments using only compass data, RGB-D camera, and GPS.  Developing intelligent machines that interact smartly with the physical world has been a long-term goal of the AI

A new algorithm generates the portamento effect between any two audio signals in real-time.  It seamlessly blends frequency segments from one audio signal into another, without increasing/decreasing the volume of signals. Musicians use an effect called ‘portamento’ to transition between notes. It

Researchers train deep neural networks on databases that contained three-body problems and their solutions.  Surprisingly, the network predicts accurate solutions at a fixed computational cost and up to 100 million times faster than the existing solver.  For over 3 centuries, mathematicians and p

A new concept presents a gun-style elevated train that floats in the air instead of running on a track.  A series of 65-feet tall magnetized loops propel the train at speed of more than 500 mph.  It would be more efficient, more sustainable, and more comfortable than flights.  One of the fastest-

Researchers demonstrate a levitating volumetric display using ultrasound waves.  The hologram provides visual, audible and tactile 3D content.  It uses arrays of ultrasonic transducers that produce soundwaves to float and control a tiny polystyrene bead.  Existing holographic displays can create

China builds an artificial sun that produces plasmas hotter than 200 million degrees Celsius.  It generates clean energy by replicating the same process that powers the sun (nuclear fission).  In China, power consumption and power generation have increased significantly in the last couple of deca

Researchers design an experiment to gather a human perspective on moral decisions made by artificial intelligence.  They analyzed millions of human responses and revealed how much ethics vary across cultures.  We are entering an era where machines are tasked not only to minimize damage but also t

Researchers crack an RSA key that is 795 bits in size and has 240 decimal digits.  The total computing time is equivalent to running a single computer core for 4,000 years.  The calculations do not pose any threat to modern computer security.  Encryption is used to protect data you receive, store

IBM develops the Global High-Resolution Atmospheric Forecasting System.  It provides 3 times more accurate results than existing global forecasting models. It offers forecasts of up to 15 hours for 25 million locations across the world. The modern age of weather forecasting began with the inventi

New biosensor-equipped eyeglasses can measure glucose levels through a person’s tears.  The process is safe and painless.  The device could also measure vitamin and alcohol levels in the blood. In the recent decade, wearable devices have created an immense commercial interest, which has stimulate

The new framework can program kirigami surfaces so that they can be integrated into soft robotics.  The technique opens new doors for designing smart soft skins with multimodal functionalities.  Kirigami is a Japanese art of paper cutting, which involves folding and then skilfully cutting the pap

The new artificial intelligence-equipped tool aims to prevent suicide among homeless youth, using limited resources.  It works by leveraging real-life social network information. It reduces the bias in coverage of homeless youth by as much as 20%.  Suicide rates in youths have increased by 300% b

Researchers use DNA molecules to store information in everyday objects.  The information can be retrieved decades or even centuries later.  At the moment the technology is quite expensive.  In today’s information age, the world’s data is growing at enormous rates. Existing devices (solid-state dr

Researchers develop the first AI named Pluribus that can defeat human experts in a multiplayer game.  Although it is specifically designed for the most popular poker format, it can defeat humans in other multiplayer games.  The AI can be used in other fields, including cybersecurity, fraud prevent

The new technique can make OLED displays brighter, with better contrast and longer life.  It involves altering the chemistry of OLED materials in such a way that it produces unique polarized light that can bypass the screen’s anti-glare filter. Modern screens of smartphones, tablets, laptops, and

The new deep learning model named MelNet can produce human intonation with uncanny accuracy. Once trained, it can regenerate anybody’s voice over a few seconds.  Researchers demonstrate how precisely it can clone Bill Gates’ voice.  There have been huge advances in machine learning techniques in
