Australian and US physicists say they have calculated the speed of the most complex nuclear reactions and found that they’re, well, really fast. We’re talking as little as a zeptosecond – a billionth of a trillionth of a second (10^-21).

The finding follows a comprehensive project to calculate detailed models of the energy flow during nuclear collisions.

Cedric Simenel from the Australian National University worked with Kyle Godbey and Sait Umar from Vanderbilt University to model 13 different pairs of nuclei, using supercomputers at ANU and in the US.

Physicists from the University of Glasgow and the University of Arizona have experimentally verified a half-century-old theory that began as speculation about how an advanced alien civilization could use a rotating black hole to generate energy.

In an experiment performed at Lawrence Berkeley National Laboratory’s 88-inch cyclotron, a team of physicists successfully created a new isotope of the human-made element mendelevium.

A 50-year-old theoretical process for extracting energy from a rotating black hole finally has experimental verification.

Using an analogue of the components required, physicists have shown that the Penrose process is indeed a plausible mechanism to slurp out some of that rotational energy — if we could ever develop the means.

That’s not likely, but the work does show that peculiar theoretical ideas can be brilliantly used to explore the physical properties of some of the most extreme objects in the Universe.

Intensity is rising at CERN. In the superconducting equipment testing hall, an innovative transmission line has set a new record for the transport of electricity. The link, which is 60 metres long, has transported a total of 54 000 amperes (54 kA, or 27 kA in either direction). “It is the most powerful electrical transmission line built and operated to date!” says Amalia Ballarino, the designer and project leader.

The line has been developed for the High-Luminosity LHC (HL-LHC), the accelerator that will succeed the Large Hadron Collider (LHC) and is scheduled to start up at the end of 2027. Links like this one will connect the HL-LHC’s magnets to the power converters that supply them.

The secret to the new line’s power can be summarised in one word: superconductivity.

An element that could hold the key to the long-standing mystery around why there is much more matter than antimatter in our universe has been discovered in Physics research involving the University of Strathclyde.

The study has discovered that an isotope of the element thorium possesses the most pear-shaped nucleus yet to be discovered.

Nuclei similar to thorium-228 may now be able to be used to perform new tests to try find the answer to the mystery surrounding matter and antimatter.

Magnetic materials have been a mainstay in computing technology due to their ability to permanently store information in their magnetic state. Current technologies are based on ferromagnets, whose states can be flipped readily by magnetic fields. Faster, denser, and more robust next-generation devices would be made possible by using a different class of materials, known as antiferromagnets. Their magnetic state, however, is notoriously difficult to control.

Now, a research team from the MPSD and the University of Oxford has managed to drive a prototypical antiferromagnet into a new magnetic state using terahertz frequency light. Their groundbreaking method produced an effect orders of magnitude larger than previously achieved, and on ultrafast time scales. The team’s work has just been published in Nature Physics.

The strength and direction of a magnet’s ‘north pole’ is denoted by its so-called magnetization. In ferromagnets, this easily reversible magnetization can represent a ‘bit’ of information, which has made them the materials of choice for magnet-based technologies. But ferromagnets are slow to operate and react to stray magnetic fields, which means they are prone to errors and cannot be packed very closely together.

Massive object cannot be explained without changing our understanding of what we know about astrophysics, researchers say.
