The key to understanding the origin and fate of the universe may be a more complete understanding of the vacuum. Read more at QuantaMagazine.org. Music is “Pulse” by Geographer.

Partnerships between engineers and biologists have begun to reveal how birds evolved their superb maneuverability. Read more at QuantaMagazine.org. Music is “Running Out” by Patrick Patrikios.

Structural studies of the robust material called sporopollenin reveal how it made plants hardy enough to reproduce on dry land. Read more at QuantaMagazine.org. Music is “Redwood Trail” by Audionautix.

Protein buildups like those seen around neurons in Alzheimer’s, Parkinson’s and other brain diseases occur in all aging cells, a new study suggests. Learning their significance may reveal new strategies for treating age-related diseases. Read more at QuantaMagazine.org. Music is “Aimless Amos” by Rondo Brothers.

Neuroscientists uncovered an energy-saving mode in vision-system neurons that works at the cost of being able to see fine-grained details. Read more at QuantaMagazine.org. Music is “Unanswered Questions” by Kevin MacLeod.

Computer scientists can now solve a decades-old problem in practically the time it takes to write it down. Read more at quantamagazine.org. Music is “Aimless Amos” by Rondo Brothers.

Jared Duker Lichtman, 26, has proved a longstanding conjecture relating prime numbers to a broad class of “primitive” sets. To his adviser, it came as a “complete shock.” Read more at quantamagazine.org. Music is “Thought Bot” by Audionautix.

The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information. Read more at quantamagazine.org. Music is “Pulse” by Geographer.

Robots are about to venture into the sunless depths of lunar craters to investigate ancient water ice trapped there, while remote studies find hints about how water arrives on rocky worlds. Read more and explore infographics at quantamagazine.org.

For centuries, mathematicians have tried to prove that Euler’s fluid equations can produce nonsensical answers. A new approach to machine learning has researchers betting that “blowup” is near. Read more at quantamagazine.org. Music is “Pulse” by Geographer.

The existence of secure cryptography depends on one of the oldest questions in computational complexity. Read more at QuantaMagazine.org. Music is “Transmission” by John Deley and the 41 Players.

Dopamine, a neurochemical often associated with reward behavior, also seems to help organize precisely when the brain initiates movements. It’s the latest revelation about the power of neuromodulators. Read more at quantamagazine.org. Music is “Pulse” by Geographer.

Biomechanical interactions, rather than neurons, control the movements of one of the simplest animals. The discovery offers a glimpse into how animal behavior worked before neurons evolved. The post This Animal’s Behavior Is Mechanically Programmed first appeared in Quanta Magazine. Music is “Running Out” by Patrick Patrikios.

Dwarf galaxies weren’t supposed to have big black holes. Their surprise discovery has revealed clues about how the universe’s biggest black holes could have formed. Read more at QuantaMagazine.org. Music is “Light Gazing” by Andrew Langdon.

Physicists are reexamining a longstanding assumption: that big stuff consists of smaller stuff. The post A Deepening Crisis Forces Physicists to Rethink Structure of Nature’s Laws first appeared on Quanta Magazine

Researchers have mapped hundreds of semantic categories to the tiny bits of the cortex that represent them in our thoughts and perceptions. What they discovered might change our view of memory. The post New Map of Meaning in the Brain Changes Ideas About Memory first appeared on Quanta Magazine

Two teams have shown how quantum approaches can solve problems faster than classical computers, bringing physics and computer science closer together. The post Machine Learning Gets a Quantum Speedup first appeared on Quanta Magazine
