Evolution calls on us to lose weight slowly over time

Posted by in categories: energy, evolution, food, health, neuroscience

| Local | http://idahostatejournal.com/ Cutting calories (dieting) and increasing caloric expenditure (exercise) cause your brain to activate neurons that will not allow you to utilize fat or lose weight.


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.

Cutting calories (dieting) and increasing caloric expenditure (exercise) cause your brain to activate neurons that will not allow you to utilize fat or lose weight.

Why it is dangerous to build ever larger big bang machines

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?”

Ethereum Plans to Cut Its Absurd Energy Consumption

Posted by in categories: bitcoin, cryptocurrencies, energy

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.

Researchers make ice repelling materials breakthrough

Posted by in categories: energy, materials

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.

Wouldn’t it be great to power your home without having enormous costs to starting a journey on the alternative road? Now, you can achieve that and also take care of your figure! The founder of the Free Electric hybrid bike, Manoj Bhargava, says that his invention uses mechanical energy in the most basic way in order to transform an hour of exercise into supplying rural household with energy for 24 hours. The mechanism is simple: when you pedals, a flywheel is put in action, which turns the generator and thus charging a battery. What better motivation to work out from now on than to power your own home without any costs whatsoever? Watch the video featured to see the bike in action.

Boeing unveils refreshed jet concept with ultra-thin wings

Posted by in categories: energy, space, transportation

SAN DIEGO (Reuters) — Boeing Co unveiled a speedier and higher-flying version of a concept plane on Tuesday aimed at sharply reducing fuel use thanks to its elongated ultra-light wings.

The so-called Transonic Truss-Braced Wing aircraft boasts a 170-foot (52 meter) wingspan that sits atop the fuselage and is braced from underneath by a truss in a design reminiscent of biplanes from the early years of aviation.

The world’s largest planemaker and U.S. space agency NASA have been studying the concept plane for nearly a decade as part of the Subsonic Ultra Green Aircraft Research program. Boeing unveiled a reconfigured model or prototype and artist’s rendering at an aerospace conference in San Diego.
