A new assay is inexpensive, simple, and can tell whether or not one of the primary drugs being used to treat malaria is genuine – an enormous and deadly problem in the developing world.

The World Health Organization has estimated that up to 200,000 lives a year may be lost due to the use of counterfeit anti-malarial drugs. When commercialized, the new technology may be able to help address that problem by testing drugs for efficacy at a cost of a few cents.


Liquid water is essential for almost every biological process so understanding liquid water is crucial for understanding biology - including some of its exceptional behavior.  

According to classical understanding, when water contacts other water, it will spread out and finally both mix together, i.e., water always completely wets water due to the hydrogen bonds formed among water molecules.



A new pressure cell makes it possible to simulate chemical reactions deep in the Earth's crust. The cell allows researchers to perform nuclear magnetic resonance (NMR) measurements on as little as 10 microliters of liquid at pressures up to 20 kiloBar.


The warm beauty of amber has been captivating and inspiring people since ancient times.

Even today, some secrets remain locked inside the fossilized tree resin. Some of the oldest recovered samples predate the rise of dinosaurs — and could outlast even the most advanced materials that science can make today. That extreme durability has made amber's internal structure so difficult to understand. 

Millions of years ago, this resin exuded from trees and then fossilized over time and techniques to probe the inner molecular architecture of amber seemed to destroy evidence of certain relationships between compounds. 


Computer technology has transformed the way we live but that is all old news 35 years into the computer revolution.

Today, consumers expect ever more from their devices - smaller size and faster speeds - and that means designers have to worry about heat. Writing in Industrial  &  Engineering Chemistry,  researchers report that liquids containing nanoparticles could help devices stay cool and keep them running.

Research into mitigating potential global warming caused by rising levels of carbon dioxide usually involves three areas: Developing alternative energy sources, capturing and storing greenhouse gases, and repurposing excess greenhouse gases.

Carbon storage will never happen, we can't even store nuclear waste in what science determined was the safest place on earth, but those other two are still possible.

Liquid Light Inc. of Monmouth Junction, N.J., got together with Andrew Bocarsly, a Princeton professor of chemistry, to devise an efficient method for harnessing sunlight to convert carbon dioxide into a potential alternative fuel known as formic acid. 


A new study has found that palladium-gold nanoparticles are excellent catalysts for cleaning polluted water - and can even convert biodiesel waste into valuable chemicals.

In dozens of studies, Rice University chemical engineer Michael Wong and colleagues have focused on using the tiny metallic specks to break down carcinogenic and toxic compounds and have now examined whether palladium-gold nanocatalysts could convert glycerol, a waste byproduct of biodiesel production, into high-value chemicals.


Chemists have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field and that paves the way for display applications using instantaneous and contactless nature of magnetic manipulation - like a poster that customizes based on the people around it.

Commercially available liquid crystals in electronic displays are composed of rod-like or plate-like molecules. When an electric field is applied, the molecules rotate and align themselves along the field direction, resulting in a rapid tuning of transmitted light.


Recently, Subway declared they would stop using a chemical because a food activist convinced people it was in yoga mats, and was therefore dangerous.

What's really dangerous are the toxic chemicals in solar panels. Soon, they could have the same ingredient as tofu, though you shouldn't stop eating tofu just because Vani Hari, the "Food Babe", can't pronounce any of the the chemicals it contains.

Cadmium chloride is currently a key ingredient in solar cell technology used in millions of solar panels around the world. This soluble compound is highly toxic and expensive to produce, requiring elaborate safety measures to protect workers during manufacture and then specialist disposal when panels are no longer needed.
