Quantum Particles Might Move Backwards Even When We Push Them Forwards

Quantum Particles Might Move Backwards Even When We Push Them Forwards

A new study published in Physical Review A suggests that, somewhat counterintuitively, quantum particles have a chance of moving backwards, even when pushed forwards. The study was carried out by scientists from the Universities of York, Munich, and Cardiff. They were investigating the idea of “backflow”, that quantum particles can move oppositely to their momentum….

Why Spider Silk Is So Effective And How to Make it

Why Spider Silk Is So Effective And How to Make it

Two papers on spider silk have coincidentally come out within a week. One announced an environmentally friendly way to replicate its remarkable features, while the other reveals one of its secrets. Together, the research could take us into a world of stronger, lighter, and more flexible wires with a multitude of uses. The capacity of…

A Photon Has Been Sent To Space Using Quantum Teleportation

A Photon Has Been Sent To Space Using Quantum Teleportation

Last month, Chinese researchers showed that quantum communication between Earth and space is possible, and now they have used the tech to send a photon to space using quantum teleportation. The experiment was conducted between Micius (the Chinese quantum satellite) and a ground station. The researchers were able to transfer the unknown quantum state from one photon…

Scientists Make The Cubest Ice Crystal Yet

Scientists Make The Cubest Ice Crystal Yet

Researchers from Ohio State University have created an extremely cubic ice crystal, and yes that’s different from an ice cube you make in the freezer. Water molecules don’t like being in a cubic structure, preferring to create hexagonal patterns (like in snowflakes). However, they can be forced into a cubic arrangement under the right conditions. The team…

First Direct Look At How Electrons Move In Sync With Vibrating Atoms

First Direct Look At How Electrons Move In Sync With Vibrating Atoms

Researchers at the SLAC National Accelerator Laboratory have taken the first direct, and most precise, measurement of electron motion in sync with vibrating atoms in an exotic material. The scientists witnessed an incredible interaction between the vibrations and electrons, describing it as a “dance”. The paper, published in Science, explains how the team used an infrared…

Physicists Observe Maxwell's Demon Brought To Quantum Life

Physicists Observe Maxwell's Demon Brought To Quantum Life

A quantum mechanical version of Maxwell’s Demon, a 150-year-old thought experiment, has been created. The demon is a simple one, and so far behaving itself. In 1867 the great physicist James Clerk Maxwell pondered the newly formulated second law of thermodynamics. One framing of the second law is that if two bodies of different temperature…

LHCb Experiment Discovers A Particle With Two Heavy Quarks

LHCb Experiment Discovers A Particle With Two Heavy Quarks

The LHCb experiment at CERN has announced the discovery of a new particle with two heavy quarks. This is the first unequivocal detection of such a particle. The new particle is called Ξcc++, and although the typeface might appear scary, it is pronounced simply as Xi-c-c-plus-plus. It is made of one up quark, which is…

Windpower's Future Rides On The Wings Of Owls And Dragonflies

Windpower's Future Rides On The Wings Of Owls And Dragonflies

Engineers seeking more efficient wind farms are looking to the wings of birds and insects, hoping millions of years of evolution will help power the clean energy revolution. “Owls are known for silent flight, owing to their unique wing features,” said Professor Hao Liu of Chiba University, Japan, in a statement. “We wanted to understand…

Protons Are Very Slightly Lighter Than We Thought

Protons Are Very Slightly Lighter Than We Thought

How heavy is a proton? It might sound like a bit of a stupid question, but we can actually figure it out with some sciency hocus pocus. And some researchers have done just that, finding it to be lighter than we thought. Researchers from the Max Planck Institute for Nuclear Physics in Germany found it was…
