When confronted with a word, the pupils begin by dilating (0 — 0.5 s), following the general activation of the brain. When this initial activation has passed, the pupils retract (0.5 — 2 s). But the size of the pupil is also determined by the luminosity evoked by the words: when we read a luminance-associated

The new study shows the structure of an important HIV protein, called the envelope glycoprotein, on a common strain of the virus. Credit: Javier Guenaga Scientists at The Scripps Research Institute (TSRI) have made another important advance in HIV vaccine design. The development was possible thanks to previous studies at TSRI showing the structures of

Around 1.75 million years ago there was a revolutionary innovation in

What our Milky Way might look like to alien astronomers: This image of NGC 2683, a spiral galaxy also known as the “UFO Galaxy” due to its shape, was taken by the Hubble Space Telescope. Since trying to find out what the Milky Way looks like is a bit like trying to picture an unfamiliar

A research team led by Dr. Ajay Kumar invents a 3-D fingerprint identification system of high efficiency and accuracy. Credit: The Hong Kong Polytechnic University The research team of The Hong Kong Polytechnic University (PolyU) has developed a system for three-dimensional (3D) fingerprint identification by adopting ground breaking 3D fingerprint minutiae recovery and matching technology,

Researchers from the CNRS, Thales, and the Universities of Bordeaux, Paris-Sud, and Evry have created an artificial synapse capable of learning autonomously. They were also able to model the device, which is essential for developing more complex circuits. The research was published in Nature Communications on

According to a new study, Americans who were married or living together had sex 16 fewer times per year in 2010-2014 compared to 2000-2004.Image Credit:Flickr/Cristiano Aguiar While the topic of sex is less taboo than it was a generation ago, that doesn’t necessarily mean people are having more of it. According to a new study

Researchers have found an explicit link between the colour of a taxi and its accident rate.

However, their exhaustive, 14-month study of each candidate’s Twitter followers–enabled by machine learning and other data science tools–offers tantalizing clues as to why the race turned out the way it did. “We wanted to
