Perovskite nanocrystals hold promise for improving a wide variety of optoelectronic devices—from lasers to light emitting diodes (LEDs) — but problems with their durability still limit the material’s broad commercial use.

Researchers at the Georgia Institute of Technology have demonstrated a novel approach aimed at addressing the material’s durability problem: encasing the inside a double-layer protection system made from plastic and silica.

In a study published Nov. 29 in the journal Science Advances, the research team describes a multistep process to produce encased perovskite that exhibit strong resistance to degradation in moist environments.

Researchers have identified a metal that conducts electricity without conducting heat — an incredibly useful property that defies our current understanding of how conductors work.

The metal, found in 2017, contradicts something called the Wiedemann-Franz Law, which basically states that good conductors of electricity will also be proportionally good conductors of heat, which is why things like motors and appliances get so hot when you use them regularly.

But a team in the US showed this isn’t the case for metallic vanadium dioxide (VO2) — a material that’s already well known for its strange ability to switch from a see-through insulator to a conductive metal at the temperature of 67 degrees Celsius (152 degrees Fahrenheit).

Human-animal hybrids are set to be developed at the University of Tokyo after the Japanese government recently lifted a ban on the controversial stem-cell research.

Hiromitsu Nakauchi—director for Stem Cell Biology and Regenerative Medicine at the University of Tokyo and team leader at Stanford’s Nakauchi Lab—is the first to receive approval for the questionable experiments which will attempt to grow human cells in rat and mouse embryos before being brought to term in a surrogate animal.

Despite many feeling that such studies are the equivalent of playing God, scientists say that the objective is far from sinister. It’s theorized that developing animals with organs constructed from human cells will create organs that can then be used for transplants in humans, cutting the long organ donation waitlists.

Earth’s magnetic North Pole has drifted so fast that authorities have had to officially redefine the location of the magnetic North Pole. The extreme wandering of the North Pole caused increasing concerns over navigation, especially in high latitudes.

Earth’s magnetic field is known to have wandered and flipped in the geologic past. Earth’s magnetic field is a result of spinning molten iron and nickel 1,800 miles below the surface. As the constant flow of molten metals in the outer core changes over time, it alters the external magnetic field.

What we’ve seen in the past hundred years is that the location of the magnetic North Pole has moved northward. That migration of the magnetic North Pole was switched into overdrive in the past few years, causing the pole to rapidly move. The increased speed with which the magnetic North Pole has moved prompted authorities to officially update its location. The official location of the magnetic poles is specified by the World Magnetic Model, which acts as the basis for navigation, communication, GPS, etc. around the globe.
