Why is Olive Oil Awesome?
Whether you sop it up with bread or use it to boost your cooking, olive oil is awesome. But a lot of chemistry goes on in that bottle that can make or break a product. Take the “extra virgin” standard: Chemistry tells us that a higher free-fatty-acid content leads to a lower grade, less tasty oil. And those peppery notes are thanks to antioxidants that contribute to olive oil’s healthy reputation. Check out the latest Reactions video for more olive oil chemistry, including how to keep yours fresh and how to best use it to give your food a flavor boost.

Dragon's Blood Could Save Your Life
This week Reactions is looking at chemistry in bizarre places that could save your life. The science within the blood of the Komodo dragon or in a horseshoe crab can help with antibiotic resistance. But it doesn't end there, so we're taking a closer look at other wild places in nature that ... more
Microbots zoom around water, destroying bacteria
One day, the tiny robot you see here could help clean up contaminated water. In places where potable sources are scarce, they can destroy disease-causing bacteria in its path and unlike conventional disinfectants, the microbots can be removed easily with a magnet. more

Growing extremely tiny, uniformly sized diamonds — without explosives
Diamonds aren’t just glittery, sparkly gems for jewelry. The smallest ones, only a few nanometers wide, are also crucial for drug delivery, sensors and quantum computer processors. Producing diamond nanoparticles that are consistently sized is important to the success of these technologies. ... more
A previously unknown bacterial enzyme makes new type of biodegradable polymer
Strings of sugars called polysaccharides are the most abundant biopolymers on Earth. Because of their versatile and environmentally friendly properties, these molecules could eventually replace some plastics. Now, researchers reporting in ACS Central Science have identified a previously unk ... more
Camels’ noses inspire a new humidity sensor
Camels have a renowned ability to survive on little water. They are also adept at finding something to drink in the vast desert, using noses that are exquisite moisture detectors. In a new study in ACS Nano, researchers describe a humidity sensor inspired by the structure and properties of ... more
