Google DeepMind CEO Demis Hassabis, one of the only people in the world with a Nobel Prize for work on artificial intelligence, shares what’s next for the world of AI.
Physicists have successfully played a mind-bending “quantum game” using a real-world quantum computer, in which lasers shuffle around ions on a chip to explore the strange behavior of qubits. By creating a special, knotted structure of entangled particles, the team demonstrated that today’s quant
These electrical pulses are communicated with other neurons through connections between them called synapses. Individual neurons have branching extensions known as dendrites that can receive thousands of electrical inputs from other cells. Dendrites transmit these inputs to the main body of the neuron, where it then integrates all these signals to generate its own electrical pulses.
It is the collective activity of these electrical pulses across specific groups of neurons that form the representations of different information and experiences within the brain.
For decades, neuroscientists have thought that the brain learns by changing how neurons are connected to one another. As new information and experiences alter how neurons communicate with each other and change their collective activity patterns, some synaptic connections are made stronger while others are made weaker. This process of synaptic plasticity is what produces representations of new information and experiences within your brain.
For more than a century, electricity has flowed through wires, powering everything from the smallest gadgets to entire cities. However, what seemed like a distant dream—wireless energy transmission—may soon become a reality. This breakthrough technology, known as “power beaming”, promises to eliminate the need for physical infrastructure, delivering power directly from one point to another using electromagnetic waves.
A stunning discovery on Mars has revealed the longest organic molecules ever found on the planet—carbon chains that could resemble building blocks of life as we know it. Preserved for billions of years in ancient Martian clay, these molecules were uncovered by NASA’s Curiosity rover and could poi
Neutrino energy offers 24/7 power without sun, wind, or fuel. Learn how this silent force may soon charge your phone and power entire homes wirelessly.
Researchers have created a new ultra-hard alloy that can survive insane temperatures. Here’s what we know about it so far.
Most cells in the human body each contain about six feet of DNA. Yet the nucleus, where DNA is coiled, is no larger than a single speck of dust. Despite its density, DNA is not a tangled ball of yarn. It is organized into intricate layers of loops that fold and unfold in response to cues from the cell.
Scientists know that the three-dimensional shape of DNA is important. This long helical thread is peppered with genes that are translated into proteins to drive cellular activity. And the structure of the genome —those layers of loops—determines which genes are active at any given time.
How the three-dimensional structure of the genome is maintained, however, is less clear. Structural changes and abnormalities are associated with many diseases, such as cancer and developmental disorders. Identifying what controls genome structure could yield targets for treatment.
Who knew that magnetic fields could be so useful?
Astronomers are able to use magnetic fields to map our environment within the Milky Way using a technique called Faraday rotation.
It works like this. There’s a bunch of dust – literal dust grains – floating within the galaxy.
