For decades, slabs of crystalline silicon have dominated the solar industry. Other materials that can be layered in thin films, such as copper indium gallium selenide (CIGS) and cadmium telluride (CdTe), have captured less than 5% of the market, because it’s hard to make them as efficient or cheap as conventional solar panels. Perovskites could be a different story. They should be cheaper to make and seem impressively efficient at converting sunlight into electricity — in the laboratory, at least.

Companies say they are close to commercializing cheap perovskite films that could disrupt solar power — but are they too optimistic?

It’s easy to imagine these wearable circuits on the shelves of CVS.

Jigang Wang and his collaborators have demonstrated light-induced acceleration of supercurrents, which could enable practical applications of quantum mechanics such as computing, sensing and communicating. Larger image. Image courtesy of Jigang Wang.

AMES, Iowa – Jigang Wang patiently explained his latest discovery in quantum control that could lead to superfast computing based on quantum mechanics: He mentioned light-induced superconductivity without energy gap. He brought up forbidden supercurrent quantum beats. And he mentioned terahertz-speed symmetry breaking.

In the future, orbiters, rovers, deep space probes, and even human space habitats will be nodes on the internet of things.

Blockchain will make sure green pledges aren’t just green wash.

When a country or a company makes a promise to reduce carbon emissions, respect fishing quotas or cut toxic output, how can we be sure they’ll keep their word?

The truth is, it’s often extremely hard. But a new initiative — Global Ledger — led by a group of World Economic Forum Young Global Leaders (YGLs) aims to change that.

Ongoing and future space missions, rising investment in new mining technologies, and the use of materials obtained from asteroids in 3D printing will drive the growth of the asteroid mining market, according to Allied Market Research.

Taking our productive capabilities, and the search for the resources that powers them, to space might one day be an inevitability.

Current guidelines recommend lowering cholesterol for heart disease risk reduction. New findings indicate that if cholesterol dips too low, it may boost the risk of hemorrhagic stroke, according to researchers.

Over a period of nine years, a Penn State-led study examined the relationship between low-density lipoprotein cholesterol—LDL, commonly known as “bad” cholesterol—and hemorrhagic stroke. This type of stroke occurs when a blood vessel bursts in the brain.

The researchers found that participants with LDL cholesterol levels below 70 mg/dL had a higher risk of hemorrhagic stroke.
