Physicists Just Confirmed Evidence of A Possible Fifth Fundamental Force

Posted by in categories: cosmology, particle physics

In Brief A deeper look into studies that were previously conducted by Hungarian physicists has recently uncovered evidence of a fifth fundamental force of nature. If confirmed, it could stand as an explanation for dark matter.

To date, there are four conventionally known fundamental forces that hold the universe together—gravity, electromagnetism, and the strong and weak nuclear forces. But a closer look at previous studies conducted by Hungarian physicists, which hinted at a new force, has led a team of scientists to evidence that the anomaly in the data could actually be a fifth force of nature.

It should be noted that the groundbreaking claim is still a very long way from being confirmed, but the current data available is enough to push research into what this new force-carrying particle is (or may be).

A virus-sized computing device

Posted by in categories: biotech/medical, computing, nanotechnology, particle physics

Researchers at University of California, Santa Barbara, have designed a functional nanoscale computing element that could be packed into a space no bigger than 50 nanometres on any side.

red blood cell nanotechnology nanotech future timeline

In 1959, renowned physicist Richard Feynman, in his talk “Plenty of Room at the Bottom” spoke of a future in which tiny machines could perform huge feats. Like many forward-looking concepts, his molecule and atom-sized world remained for years in the realm of science fiction. And then, scientists and other creative thinkers began to realise Feynman’s nanotechnological visions.

Thermoelectric paint generates electricity from almost any heat source

Posted by in categories: materials, particle physics

Thermoelectric generators convert heat or cold to electricity (and vice-versa). Normally solid-state devices, they can be used in such things as power plants to convert waste heat into additional electrical power, or in small cooling systems that do not need compressors or liquid coolant. However the rigid construction of these devices generally limits their use to flat, even surfaces. In an effort to apply thermal generation capabilities to almost any shape, scientists at the Ulsan National Institute of Science and Technology (UNIST) in Korea claim to have created a thermoelectric coating that can be directly painted onto most surfaces.

Variously known as the Peltier, Seebeck, or Thomson effect, the thermoelectric effect is seen in semiconductor devices that create a voltage when a different temperature is present on each side or, when a voltage is applied to the device, it creates a temperature difference between the two sides. In this instance, the new paint created by the UNIST researchers is used specifically to heat a surface when a voltage is applied.

The specially-formulated inorganic thermoelectric paint was created using Bi2Te3 (bismuth telluride) and Sb2Te3 (antimony telluride) particles to create two types of semiconducting material. To test the resultant mixture, the researchers applied alternate p-type (positive) and n-type (negative) layers of the thermoelectric semiconductor paint on a metal dome with electrodes at the top and the base of the dome.

Extremely Rare Quantum Spin Liquid Observed In Crystal Point

Posted by in categories: particle physics, quantum physics

Quantum spin liquid, a very rare state of matter, has been observed in a new crystal especially designed with the hopes of using its unique quantum properties.

The crystal, an ytterbium compound with the formula YbMgGaO4, was first synthesized by Chinese scientists for the first time in 2015. Now, in a new study published in the journal Nature, researchers from the United States suggest that the new material can produce a quantum spin liquid when frozen to temperatures near absolute zero. At present, only a few materials are believed to possess these properties.

Artificial intelligence and the evolution of the fractal economy

Posted by in categories: biotech/medical, economics, finance, particle physics, robotics/AI

Money makes the world go round, or so they say. Payments, investments, insurance and billions of transactions are the beating heart of a fractal economy, which echoes the messy complexity of natural systems, such as the growth of living organisms and the bouncing of atoms.

Financial systems are larger than the sum of their parts. The underlying rules that govern them might seem simple, but what surfaces is dynamic, chaotic and somehow self-organizing. And the blood that flows through this fractal heartbeat is data.

Today, 2.5 exabytes of data are being produced daily. That number is expected to grow to 44 zettabytes a day by 2020 (Source: GigaOm). This data, along with interconnectivity, correlation, predictive analytics and machine learning, provides the foundation for our AI-powered future.

New blow for ‘supersymmetry’ physics theory

Posted by in categories: futurism, particle physics

In a new blow for the futuristic “supersymmetry” theory of the universe’s basic anatomy, experts reported fresh evidence Monday of subatomic activity consistent with the mainstream Standard Model of particle physics.

New data from ultra high-speed proton collisions at Europe’s Large Hadron Collider (LHC) showed an exotic particle dubbed the “beauty quark” behaves as predicted by the Standard Model, said a paper in the journal Nature Physics.

Previous attempts at measuring the beauty quark’s rare transformation into a so-called “up quark” had yielded conflicting results. That prompted scientists to propose an explanation beyond the Standard Model—possibly supersymmetry.

Majorana Particles Observed for 1st Time: Contain Their Own Antiparticles –“Impacts Future of Quantum Computers”

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

Around 75 years ago, Italian physicist Ettore Majorana hypothesized the existence of exotic particles that are their own antiparticles. Since then, interest in these particles, known as Majorana fermions, has grown enormously given that they could play a role in creating a quantum computer. Majoranas have already been described very well in theory. However, examining them and obtaining experimental evidence is difficult because they have to occur in pairs but are then usually bound to form one normal electron. Ingenious combinations and arrangements of various materials are therefore required to generate two Majoranas and keep them apart.

The Missing Universe: CERN Has Started Searching for “Dark Photons”

Posted by in categories: cosmology, particle physics

In Brief

  • Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe.
  • Physicists from CERN now believe there’s a fifth universal force that rules the behavior of dark matter, and is transmitted by a particle called the dark photon.
