What makes PSR J1748–2446 famous for its weirdness? Easy. It is the celestial object that spins the fastest in the universe. It’s also a star whose surface is not just solid, but harder than a diamond. Compared to lead, its density is 50 trillion times higher. Compared to our Sun, its magnetic field sizzles a trillion times more intensely. It is, in essence, the most extreme form of neutron star.

When a heavy sun explodes in a supernova, the core of the sun, which has the mass of several million Earths, collapses into a tiny sphere and the rest of the sun shoots outward. This is how neutron stars are created. When this occurs, the inverse-square law of gravity goes into its demo-mode with a vengeance.

Explore the fascinating world of quantum teleportation. Discover its principles, applications, and the profound impact it could have on our future.

Introduction to Quantum Teleportation

Quantum teleportation, a term that sounds like it’s straight out of science fiction, is a very real and advancing field in quantum physics. This groundbreaking technology is not about transporting matter from one place to another but rather involves the transfer of information between quantum particles. This article delves into the science behind quantum teleportation, its potential applications, and the impact it could have on various aspects of our lives.

There’s a hot new BEC in town that has nothing to do with bacon, egg, and cheese. You won’t find it at your local bodega, but in the coldest place in New York: the lab of Columbia physicist Sebastian Will, whose experimental group specializes in pushing atoms and molecules to temperatures just fractions of a degree above absolute zero.

Scientists at the Cavendish Laboratory have discovered spin coherence in Hexagonal Boron Nitride (hBN) under normal conditions, offering new prospects for quantum technology applications.

Cavendish Laboratory researchers have discovered that a single ‘atomic defect’ in a material known as Hexagonal Boron Nitride (hBN) maintains spin coherence at room temperature and can be manipulated using light.

Spin coherence refers to an electronic spin being capable of retaining quantum information over time. The discovery is significant because materials that can host quantum properties under ambient conditions are quite rare.

In May 2022, the Facility for Rare Isotope Beams (FRIB) at Michigan State University (MSU), launched its precision measurement program. Staff from FRIB’s Low Energy Beam and Ion Trap (LEBIT) facility take high-energy, rare-isotope beams generated at FRIB and cool them to a lower energy state. Afterward, the researchers measure specific particles’ masses at high precision.

Miniaturizing could therefore lead to widespread adoption. Creating night vision filters that weigh less than a gram and can sit as a film across a pair of traditional spectacles opens up new, everyday applications.

Consumer night vision glasses that allow the user to see the visible and at the same time could result in safer driving in the dark, safer nighttime walks, and less hassle working in low-light conditions that currently require bulky and often uncomfortable headlamps.

In research published in Advanced Materials, TMOS researchers from the Australian National University demonstrate enhanced infrared vision non-linear upconversion technology using a non-local lithium niobate metasurface.

Recent high profile controversies haven’t deterred scientists from searching for one of research’s ultimate prizes: room temperature superconductors. Kit Chapman reports on the claims.

In July 2023, the world became obsessed with superconductivity. Two pre-prints from a group in South Korea claimed that a copper-doped lead-apatite, dubbed LK-99 after its two proposers, Lee Sukbae and Kim Ji-Hoon, was a superconductor at room temperature and ambient pressure. The claims spread across social media, with both seasoned groups and amateur chemists trying to recreate the material. By August, a consensus was reached that LK-99 was yet another dead end, and not a superconductor at all.

The news followed a paper in Nature that proposed another room-temperature superconductor, this time only showing its properties at intense pressures, by Ranga Dias at the University of Rochester in the US. Yet Dias’ claims have now been retracted, and his data and academic reputation have been brought into question amid allegations of research fraud and plagiarism.
