A Chicago-based entrepreneur says many industrial power users can save money, get more electricity, and reduce greenhouse gas emissions by using the energy they already consume more efficiently. It’s called recycling energy — capturing waste heat and turning it into power.

This new household appliance turns it into energy.

Chiral surfaces, which have differing responses for left- and right-handed circularly polarized (LCP and RCP) light, can be useful in optical experimentation. Metamaterials, which can be made into circular polarizers, are promising for creating chiral surfaces. Scientists at the Missouri University of Science and Technology (Rolla, MO) and the Argonne National Laboratory (Argonne, IL) have now created a chiral metamaterial-absorbing surface that has a large circular dichroism (CD) over the 1.3–1.8 μm spectral region. The chiral absorber could be useful for optical filters, thermal energy harvesting, optical communications, and chiral imaging.

A chiral optical metasurface selectively absorbs either left- or right-handed circularly polarized light; it could be useful in imagers and other optical systems.

Scientists analyzed the gamma rays emitted during the NPDGamma Experiment and found parity-violating asymmetry, which is a specific change in behavior in the force between a neutron and a proton. They measured a 30 parts per billion preference for gamma rays to be emitted antiparallel to the neutron spin when neutrons are captured by protons in liquid hydrogen. After observing that more gammas go down than up, the experiment resolved for the first time a mirror-asymmetric component or handedness of the weak force.

For the first time ever, an international team of researchers imaged the microscopic state of negative capacitance. This novel result provides researchers with fundamental, atomistic insight into the physics of negative capacitance, which could have far-reaching consequences for energy-efficient electronics.

Recently, and at a most appropriate time, another study published in the journal eLife has given explanation as to why your current New Year’s Resolution diet will not work.

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?

CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.

Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”

“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”

The problems with cryptocurrencies and their energy usage are well-known. However, Ethereum is planning to address the issue. They’re planning on doing a 99% decrease in the amount of energy used in obtaining new coins.

It would be good for other cryptocurrencies to take this problem just as seriously.

The cryptocurrency is going on an energy diet to compete with more efficient blockchains.

Ice is one of the most significant hazards to drivers and pilots and is blamed for multibillion-dollar losses each year in the US. Ice causes all manner of delays in air travel and damages infrastructure, power generation equipment, and power transmission facilities each year. Scientists from the University of Houston have made a breakthrough in repelling ice that could have uses in multiple industries.
