Lack of symmetry in qubits can’t fix errors in quantum computing, might explain matter/antimatter
A team of quantum theorists seeking to cure a basic problem with quantum annealing computers—they have to run at a relatively slow pace to...
A new study reveals that quantum physics can cause mutations in our DNA
Quantum biology is an emerging field of science, established in the 1920s, which looks at whether the subatomic world of quantum mechanics plays a...
The Milky Way may be swarming with planets with oceans and continents like here...
Astronomers have long been looking into the vast universe in hopes of discovering alien civilisations. But for a planet to have life, liquid water...
New ‘metalens’ shifts focus without tilting or moving
Polished glass has been at the center of imaging systems for centuries. Their precise curvature enables lenses to focus light and produce sharp images,...
Ghost particle from shredded star reveals cosmic particle accelerator
Tracing back a ghostly particle to a shredded star, scientists have uncovered a gigantic cosmic particle accelerator. The subatomic particle, called a neutrino, was...
New technology enables predictive design of engineered human cells
Northwestern University synthetic biologist Joshua Leonard used to build devices when he was a child using electronic kits. Now he and his team have...
Global study of 48 cities finds nature sanitizes 41.7 million tons of human waste...
The first global-scale assessment of the role ecosystems play in providing sanitation finds that nature provides at least 18% of sanitation services in 48...
Conservation paradox: The pros and cons of recreational hunting
Recreational hunting—especially hunting of charismatic species for their trophies—raises ethical and moral concerns. Yet recreational hunting is frequently suggested as a way to conserve...
Release of nutrients from lake-bottom sediments worsens Lake Erie’s annual ‘dead zone’
Robotic laboratories on the bottom of Lake Erie have revealed that the muddy sediments there release nearly as much of the nutrient phosphorus into...
A speed limit also applies in the quantum world
Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn...
Time-lapse reveals the hidden dance of roots
Duke researchers have been studying something that happens too slowly for our eyes to see. A team in biologist Philip Benfey's lab wanted to...
