Hoverboards and certain cell phones powered by lithium-ion batteries occasionally go up in flames. Scientists now have a new plan for squelching these fires before they flare out of control: incorporating a flame retardant in the battery that’s released if temperatures get too toasty.
Within lithium-ion batteries, ions travel between positive and negative electrodes through a liquid called an electrolyte. But commonly used electrolytes are highly flammable. And if a short circuit in the battery produces enough heat, the electrolyte can ignite.

The Samsung Galaxy Note 7 exploding battery fiasco has stirred major concerns whether smartphone batteries are really safe. In an effort to prevent these disasters from happening, a group of Stanford scientists have developed a lithium-ion battery pack, which includes a capsule filled with triphenyl phosphate (TPP). Once the battery’s internal temperature reaches a certain point, the capsule will melt releasing the TPP and extinguishing the fire.

The team working on the project found out that TPP is a type of chemical-fire retardant. The chemical is capable of extinguishing an exploding battery in just 0.4 seconds, according to 9to5Google. The team also set the temperature threshold at 302 degrees Fahrenheit, at that point, the capsule will melt releasing the TPP chemical.

It was not so long ago that sequencing even tiny snippets of DNA was a costly, cumbersome process that required access to a state-the-art lab. Today, we are inching close to putting a DNA sequencer in every pocket.

Very cool.
Scientists have developed a new 5D technique for analysing images, an advance that may make it easier to quickly find tell-tale signs of diseases from pictures taken using cell phones. Called “Hyper-Spectral Phasor” analysis, or HySP, it is much faster and far less expensive than current techniques, and may be useful for diagnosing and monitoring diseases by using cell phone images, researchers said.
Through the new imaging technology, researchers at the University of Southern California (USC) in the US have used fluorescent imaging to locate proteins and other molecules in cells and tissues. It works by tagging the molecules with dyes that glow under certain kinds of light – the same principle behind so-called “black light” images.
Fluorescent imaging can help scientists understand which molecules are produced in large amounts in cancer or other diseases, information that may be useful in diagnosis or in identifying possible targets for therapeutic drugs.
