Non-profit’s $300 hepatitis C cure as effective as $84,000 alternative

Rolls-Royce and Boeing invest in UK space engine

Key technologies include a compact pre-cooler heat-exchanger that can take an incoming airstream of over 1,000C and cool it to -150C in less than 1/100th of a second. This would permit Sabre to use oxygen direct from the atmosphere for combustion instead of carrying it in a tank with the weight penalty that implies.

Slow-Motion Ocean: Atlantic’s Circulation Is Weakest in 1,600 Years

In recent years sensors stationed across the North Atlantic have picked up a potentially concerning signal: The grand northward progression of water along North America that moves heat from the tropics toward the Arctic has been sluggish. If that languidness continues and deepens, it could usher in drastic changes in sea level and weather around the ocean basin.

Depthwise separable convolutions for machine learning

Convolutions are an important tool in modern deep neural networks (DNNs). This post is going to discuss some common types of convolutions, specifically regular and depthwise separable convolutions. My focus will be on the implementation of these operation, showing from-scratch Numpy-based code to compute them and diagrams that explain how things work.

Looking to Listen: Audio-Visual Speech Separation

People are remarkably good at focusing their attention on a particular person in a noisy environment, mentally “muting” all other voices and sounds. Known as the cocktail party effect, this capability comes natural to us humans. However, automatic speech separation — separating an audio signal into its individual speech sources — while a well-studied problem, remains a significant challenge for computers.

Tesla Full Self-Driving Images Leaked

Tesla’s full self-driving autonomous vehicle feature is coming. An image leaked on Tuesday apparently shows the new user interface of a test-car. The image shows how the autopilot software/system views and interprets the world.

Japan team maps ‘semi-infinite’ trove of rare earth elements

The deposit, found within Japan’s exclusive economic zone waters, contains more than 16 million tons of the elements needed to build high-tech products ranging from mobile phones to electric vehicles, according to the study, released Tuesday in the journal Scientific Reports.
