To Pay Attention, the Brain Uses Filters, Not a Spotlight | Quanta Magazine
We can pick out a conversation in a loud room, amid the rise and fall of other voices or the hum of an air conditioner. We can spot a set of keys in a sea of clutter, or register a raccoon darting into the path of our onrushing car. Somehow, even with massive amounts of information flooding our senses, we’re able to focus on what’s important and act on it. Attentional processes are the brain’s way
Mathematician Solves Computer Science Conjecture in Two Pages | Quanta Magazine
A paper posted online this month has settled a nearly 30-year-old conjecture about the structure of the fundamental building blocks of computer circuits. This “sensitivity” conjecture has stumped many of the most prominent computer scientists over the years, yet the new proof is so simple that one researcher summed it up in a single tweet. “This conjecture has stood as one of the most frustrating
What the Sight of a Black Hole Means to a Black Hole Physicist | Quanta Magazine
We knew the words already, the standard lore: All forms of matter and energy bend space and time, and light and matter follow those curves. The words have to be taken on trust. But the mathematics we could acquire. It would belong to us. When Einstein conceived of relativity, he gave us a gift that has been passed from person to person around the world. Relativity, defying its name, is true for al
Milestone Experiment Proves Quantum Communication Really Is Faster | Quanta Magazine
Quantum computers are still a dream, but the era of quantum communication is here. A new experiment out of Paris has demonstrated, for the first time, that quantum communication is superior to classical ways of transmitting information. “We are the first to show a quantum advantage for transmitted information that two parties have to share to perform a useful task,” said Eleni Diamanti, an electri
What a Newfound Kingdom Means for the Tree of Life | Quanta Magazine
The tree of life just got another major branch. Researchers recently found a certain rare and mysterious microbe called a hemimastigote in a clump of Nova Scotian soil. Their subsequent analysis of its DNA revealed that it was neither animal, plant, fungus nor any recognized type of protozoan — that it in fact fell far outside any of the known large categories for classifying complex forms of life
Neutral Theory of Evolution Challenged by Evidence for DNA Selection | Quanta Magazine
When Charles Darwin articulated his theory of evolution by natural selection in On the Origin of Species in 1859, he focused on adaptations — the changes that enable organisms to survive in new or changing environments. Selection for favorable adaptations, he suggested, allowed ancient ancestral forms to gradually diversify into countless species. That concept was so powerful that we might assume
