Mystery of Heat Loss from Earth's Crust Solved

By discovering a new type of seafloor vent system, a group of scientists has solved the mystery of heat loss from the Earth’s crust, a finding that can also help scientists interpret the evidence for past global climates more accurately.
The discovery explains the long observed disconnect between the theoretical rate at which the Earth's crust is cooling at seafloor spreading ridge flanks and actual observations.

Google Working on Artificial Intelligence

Google is working on a new messaging app which will provide answers to the users' queries by using artificial intelligence.
The aim of the app is to allow users to engage with chatbots as another medium of getting search results and other information.
In a similar move, Social networking website Facebook is also working on an A.I.-based assistant, called "M," which is part of the company's Messenger app.

Brain Activity of Worms Recorded in 3D

Scientists have developed a new method to record 3D footage of neural activity in nearly the entire brain of a free-moving animal. This development could help better understand how neurons coordinate action and perception in animals.
Researchers used the technique to capture the first 3D recordings of neural activity in the nematode Caenorhabditis elegans, a worm species 1 millimetre long with a nervous system containing a mere 302 neurons.

Processor Capable of Transmitting Data Using Light

A team of engineers has demoed the first processor that uses light for ultrafast communications.
The researchers packed two processor cores with more than 70 million transistors and 850 photonic components onto a 3-by-6-millimeter chip.
The new chip marks the next step in the evolution of fiber optic communication technology by integrating into a microprocessor the photonic interconnects, or inputs and outputs (I/O), needed to talk to other chips.

Incredible Galactic Tail Discovered

NASA’s Chandra X-ray Observatory has discovered an extraordinary ribbon of hot gas trailing behind a galaxy like a tail.
This ribbon, or X-ray tail, is likely due to gas stripped from the galaxy as it moves through a vast cloud of hot intergalactic gas.
With a length of at least 250,000 light years, it is likely the largest such tail ever detected.
The tail is located in the galaxy cluster Zwicky 8338, which is almost 700 million light years from Earth.
