NASA engineer introduces the helical engine that can take us to interstellar distances without refueling. With enough power and time, it would be able to attain 99% of the speed of light. The concept is quite bizarre but worth exploring. Deep...
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. ...
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...
A new study suggests that the Dark Ages completely ended around 12 billion years ago. This is when the first generation of stars and galaxies lit up the universe. It is estimated that our universe is 13.8 billion years old, with an uncertainty of...
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...
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...
Fish are found in almost every marine environment, from the deepest ocean trenches to mountain streams high above the sea level. They have been used as a major source of food since the beginning of recorded history. Traditionally, extant fish...
Kaolin is a new comprehensive PyTorch library that moves 3D models into the realm of neural networks. It is packed with many graphics components, including rendering, shading, and lightning. It cuts down the task for creating a 3D model for deep...
No matter how sophisticated our technology gets or how well we know the laws of nature, we will always be at the mercy of our mother nature. On average, about 60,000 people die per year due to natural disasters. They are responsible for about 0.1%...
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...
Obesity could trigger inflammation in the nervous system, damaging crucial parts of the brain. These alterations in the brain are responsible for cognitive functions, emotions, and control of appetite. In recent decades, obesity in children and...
Max IV is the most powerful synchrotron of its kind and the brightest light source in the world. It accelerates bunches of electrons to a speed of up to 99.9999999985% of the speed of light, in a 528-meter storage ring with a diameter of 1 cm. MAX...
