Higgs boson possibly caught in act of never-before-seen transformation

Posted by in category: particle physics

If the Higgs boson really is decaying into pairs of muons in the Large Hadron Collider, that’s a big deal for particle physics.

RHIC Collider Creates Quark-Gluon Plasma at 4,000,000,000,000 Degrees Celsius

Posted by in categories: cosmology, particle physics

Circa 2010

Until the LHC finally gets up to full speed, Brookhaven National Lab’s Relativistic Heavy Ion Collider (RHIC) remains the world’s most powerful heavy ion smasher. And on Monday, they showed off some of that power by announcing that a recent collision resulted in the hottest matter ever recorded. Coming in at a scorching 7.2 trillion degrees Fahrenheit, the plasma not only recreated the environment of the Big Bang, but might have also resulted in the temporary formation of a bubble within which some normal laws of physics did not apply.

‘Quark Fusion’ Could Outperform Nuclear Fusion

Posted by in categories: nuclear energy, particle physics

Circa 2017

In a few decades, we might get all our power from nuclear fusion. Researchers have been working to build functional nuclear fusion reactors, which mimic the fusion reactions that occur in the sun to generate power. Once we figure out fusion power, we could use these generators to power our lives for decades.

Rippling graphene harvests thermal energy

Posted by in categories: materials, particle physics

New technology could deliver “clean, limitless, low-voltage power for small devices”.

The rippling thermal motion of a tiny piece of graphene has been harnessed by a special circuit that delivers low-voltage electrical energy. The system was created by researchers in US and Spain, who say that if it could be duplicated enough times on a chip, it could deliver “clean, limitless, low-voltage power for small devices”.

The new heavy isotope mendelevium-244 and a puzzling short-lived fission activity

Posted by in categories: chemistry, particle physics

Gaining a better understanding of the limiting factors for the existence of stable, superheavy elements is a decade-old quest of chemistry and physics. Superheavy elements, as are called the chemical elements with atomic numbers greater than 103, do not occur in nature and are produced artificially with particle accelerators. They vanish within seconds.

A team of scientists from GSI Helmholtzzentrum fuer Schwerionenforschung Darmstadt, Johannes Gutenberg University Mainz (JGU), Helmholtz Institute Mainz (HIM) and the University of Jyvaeskylae, Finland, led by Dr. Jadambaa Khuyagbaatar from GSI and HIM, has provided new insights into the processes in those exotic and for this, has produced the hitherto unknown nucleus mendelevium-244. The experiments were part of “FAIR Phase 0,” the first stage of the FAIR experimental program. The results have now been published in the journal Physical Review Letters.

Heavy and superheavy nuclei are increasingly unstable against the fission process, in which the nucleus splits into two lighter fragments. This is due to the ever-stronger Coulomb repulsion between the large number of positively charged protons in such nuclei, and is one of the main limitations for the existence of stable superheavy nuclei.

Does Consciousness Create Reality? Double Slit Experiment may show the Answer

Posted by in categories: neuroscience, particle physics, quantum physics

The double slit experiment — Does consciousness create reality? Quantum mechanics shows us that particles are in superposition, meaning they can exist in different states and even multiple places at the same time. They are nothing more than waves of probabilities, until the moment that they are measured. One interpretation of this phenomenon is that the measurement being made requires a measurer, or a conscious observer. If this is correct, then it implies that consciousness has to be is an integral part of creating the world that we observe. Could this consciousness then be required for creating reality? Does this mean that there would be no reality without consciousness?

Experiments can show that what we think of as particles behave like waves. Waves of probabilities. This is the foundation of Quantum mechanics. The famous double slit experiment illustrates this. What is bizarre is that when you try to find out what’s going on at the slits by placing a detector at the two slits to try to figure out which slit the individual atoms are going through – the “WHICH WAY” information, they all of a sudden stop behaving like waves, and behave like particles.

Quantum Tunnels Show How Particles Can Break the Speed of Light

Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls.

New insight brings sustainable hydrogen one step closer

Posted by in categories: chemistry, particle physics, sustainability, transportation

Leiden chemists Marc Koper and Ian McCrum have discovered that the degree to which a metal binds to the oxygen atom of water is decisive for how well the chemical conversion of water to molecular hydrogen takes place. This insight helps to develop better catalysts for the production of sustainable hydrogen, an important raw material for the chemical industry and the fuel needed for environmentally friendly hydrogen cars. Publication in Nature Energy.

For years there has been a heated debate in the literature: how to speed up the electrochemical production of on platinum electrodes in an alkaline environment? Chemist Ian McCrum watched from the sidelines and concluded that part of the debate was caused by the fact that the debaters were looking at slightly different electrodes, making the results incomparable. Time to change that, McCrum thought, who was a LEaDing Fellow postdoc in the group of Professor Marc Koper at the time.

11 Years Charting The Edge of The Solar System

Posted by in categories: particle physics, space

Our Interstellar Boundary Explorer launched to space 12 years ago today!

IBEX studies our solar system’s boundary to interstellar space by measuring particles that rocket back towards Earth from the edge of the heliosphere, the vast bubble generated by the Sun’s magnetic field that envelops all the planets. Scientists recently used an entire solar cycle’s worth of data to explore how this boundary changes throughout the Sun’s activity cycles. https://www.nasa.gov/feature/goddard/2020/nasa-ibex-charts-1…sphere-sun
