Google Just Indexed Millions of ‘Life Magazine’ Photos Using Artificial Intelligence

The search giant, which debuted a website for the photo project on Wednesday, said it was able to categorize over 4 million iconic Life Magazine photographs without human help. After clicking on a particular label like “skateboarding,” for example, users are shown photos of people performing skateboard tricks along with Wikipedia’s definition of the sport. […]

Open Sourcing the Hunt for Exoplanets

Recently, we discovered two exoplanets by training a neural network to analyze data from NASA’s Kepler space telescope and accurately identify the most promising planet signals. And while this was only an initial analysis of ~700 stars, we consider this a successful proof-of-concept for using machine learning to discover exoplanets, and more generally another example […]

Reptile: A Scalable Meta-Learning Algorithm

We’ve developed a simple meta-learning algorithm called Reptile which works by repeatedly sampling a task, performing stochastic gradient descent on it, and updating the initial parameters towards the final parameters learned on that task. This method performs as well as MAML, a broadly applicable meta-learning algorithm, while being simpler to implement and more computationally efficient. […]

Researchers Can ‘See’ Your Memories While You Sleep

New research published today by Cairney and his colleagues in Current Biology has made significant headway on this issue by linking sleep spindles—spontaneous bursts of brain activity—to memory processing in a sleeping brain. Incredibly, the researchers claim it is possible to determine the content of the memory being processed by analyzing this brain activity. Source: […]

Can retrocausality solve the puzzle of action-at-a-distance?

Einstein’s objections to quantum mechanics began very early. Schrödinger’s version of the theory introduced a new mathematical entity, the wave function, which seemed to allow the position of an unmeasured particle to be spread out across an arbitrarily large region of space. When the particle’s position was measured, the wave function was said to ‘collapse’, […]

Brain tissue samples suggest we stop growing new neurons in our early teens

Two brain samples reveal how neurogenesis changes over time. At left, a sample from an infant brain reveals young neurons (green) in the hippocampus alongside more mature neurons (red), At right, mature neurons predominate in an adult human hippocampus.

The Worsening Cosmic Ray Situation

The story begins four years ago when Schwadron and colleagues first sounded the alarm about cosmic rays. Analyzing data from the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) instrument onboard NASA’s Lunar Reconnaissance Orbiter (LRO), they found that cosmic rays in the Earth-Moon system were peaking at levels never before seen in the […]

Scientists find odd and amazing cyclones at Jupiter’s poles

This composite image, derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA’s Juno mission to Jupiter, shows the central cyclone at the planet’s north pole and the eight cyclones that encircle it. Source: arstechnica

Why Is China Burning Up Its Space Station in the Sky?

Tiangong-1, China’s first space station, is hurtling toward its doom. Launched in September 2011, the 10-meter (34-foot) long spacecraft hosted two crews of “taikonauts,” the term for Chinese astronauts, and laid the groundwork for China’s Tiangong program, which aims to establish a third-generation multi-module space station in orbit during the 2020s.
