Topological insulators are quantum materials, which, due to their exotic electronic structure, on surfaces and edges conduct electric current like metal, while acting as an insulator in bulk. Scientists from the Max-Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) have demonstrated for the first time how to tell apart topological materials from their regular—trivial—counterparts within a millionth of a billionth of a second by probing it with ultra-fast laser light. Their method could open the way for such materials to be used as logic elements in light-controlled electronics able to process information tens of thousands times faster as currently possible. Their study appeared in Nature Photonics.

The most common illustration of the topology concept involves an elastic pretzel, which can be stretched, bent, or twisted in any way; no matter the deformation, it is impossible to make a bagel out of a pretzel or add holes to it, without tearing it apart. The number of holes in a pretzel is thus invariant and provides topological information about the pretzel shape.

In a solid material, quantum-mechanical laws restrict which energies electrons can have, leading to the formation of bands with either allowed or forbidden energies. Using the concept of topology, physicists can describe complex shapes of allowed energy bands and assign them a specific topological number. A special topology of the band structure in a material system manifests itself in exotic properties that can be observed—such as the surface conductivity in topological insulators.

This new breed of city takes various different forms, from government initiatives, to public-private partnerships, to entirely private enterprises. Many are being used to jump-start economies in the developing world, with masterplans carefully calibrated to attract foreign investors and treasuries looking to sink their funds into something concrete. They provide a powerful means for wealthy countries to expand their strategic influence abroad, with the construction of new cities acting as a form of “debt-trap diplomacy”, tying host nations into impossibly burdensome deals. They are billed as a panacea for the world’s urban ills, solving overcrowding, congestion and pollution; yet, more often than not, they turn out to be catalysts for land dispossession, environmental degradation and social inequality.

The feature Kim enjoys most is a small touchscreen display on his kitchen wall that allows him to keep track of his and his wife’s consumption of electricity, water and gas and, most important, compare it against the average statistics for the building. Flicking between the screens of bar charts and graphs, a broad grin spreads across his face: for yet another day running, they are more energy-efficient than all their neighbours.

From their living room window at the top of one of the city’s new residential towers, a panorama of downtown Songdo unfolds. Across an eight-lane highway lies Central Park, a broad swath of trees surrounding an ornamental lake, flanked by rows of glass towers with vaguely jaunty silhouettes. Armies of identikit concrete apartment blocks march into the hazy distance beyond, terminating at a Jack Nicklaus-designed golf course. It looks a lot like many other modern Asian cities, a place of generic towers rising above a car-dominated grid. Public life is mostly confined to the air-conditioned environments of malls and private leisure clubs.

The devices, developed by a European research team, are said to have twice the energy density of conventional aluminum devices. The scientists used a cathode made of anthraquinone, instead of one based on graphene, increasing energy density.

Coenzyme Q10, or CoQ10, is a compound that generates energy in your cells and has a wide range of health benefits. Here are 9 benefits of coenzyme Q10.

Theory suggests that empty space is filled with enormous energy, but according to a new proposal this energy may be hidden because its effects cancel at the tiniest scales.

An international team of scientists has figured out how to capture heat and turn it into electricity.

The discovery, published last week in the journal Science Advances, could create more efficient energy generation from heat in things like car exhaust, interplanetary space probes and industrial processes.

“Because of this discovery, we should be able to make more electrical energy out of heat than we do today,” said study co-author Joseph Heremans, professor of mechanical and aerospace engineering and Ohio Eminent Scholar in Nanotechnology at The Ohio State University. “It’s something that, until now, nobody thought was possible.”

A new initiative by Florida Power & Light aims to to install 1,000+ charging ports at 100+ locations across Florida, including major roadways, large employers and popular tourism destinations.

Florida Power & Light is committing to EVs in a big way. In an announcement today, the Juno Beach-based company revealed that its would be rolling out 1,000 new EV charging points at 600 stations.

They’ll be distributed across 100 different locations. Some will serve employees of large corporations in the area like Office Depot. Shopping malls, public schools and municipal buildings are also in the mix, as are popular tourist spots like Lion Country Safari.

If you are a Lifeboat subscriber or have been reading these pages for awhile, you may know why it’s called “Lifeboat”. A fundamental goal of our founder, board, writers and supporters is to sustain the environment, life in all its diversity, and—if necessary—(i.e. if we destroy our environment beyond repair, or face a massive incoming asteroid), to prepare for relocating. That is, to build a lifeboat, figuratively and literally.

But most of us never believed that we would face an existential crisis, except perhaps a potential for a 3rd World War. Yet, here we are: Burning the forests, killing off unspeakable numbers of species (200 each day), cooking the planet, melting the ice caps, shooting a hole in the ozone, and losing more land to the sea each year.

Regading the urgent message of Greta Thunberg, below, I am at a loss for words. Seriously, there is not much I can add to the 1st video below.

Information about climate change is all around us. Everyone knows about it; Most people understand that it is real and it that poses an existential threat, quite possibly in our lifetimes. In our children’s lives, it will certainly lead to war, famine, cancer, and massive loss of land, structures and money. It is already raising sea level and killing off entire species at thousands of times the natural rate.
