One Man’s Waste Soot is Another Man’s Rechargeable Battery Unwanted marine vessel engine soot may be an ideal ingredient for rechargeable lithium ion battery anodes

Rechargeable lithium-ion batteries are important in our lives as we use them frequently in our smartphones, laptops, tablets, power tools, and electric vehicles. They are even used to help power the Mars Curiosity rover! Typically, graphite, the form of carbon READ MORE

Science Makes it Harder for Criminals to Cover Their Tracks Thermal images of a suspect’s shoes may be able to tell scientists if their alibi checks out

We’re all familiar with “heat signatures” and “infrared images” thanks to the numerous cop shows on television. You’d be surprised to know, though, that in the real (not reel) world, images from a thermal camera are not accepted as evidence READ MORE

Turn Genes on With the Flip of a Switch! Light-activated DNA shines a spotlight on new gene therapies.

The 1997 US film Men In Black followed two secret agents who protected humans from extraterrestrial aliens, and aliens from humans. They had access to several (fictional) gadgets — the most notable of which was the “neuralizer.” The neuralizer allowed READ MORE

Command a Robot By Tilting Your Head New advances in robotic control systems allows wearers of Google Glass to control a robot, hands-free!

Many marvel at the immense computing power available in modern day wearable devices. However, few appreciate the many sensors that work together in these devices. Wearable electronics contain many sensors that continually collect data. Picture a smartwatch or personal health READ MORE

Would a Self-Driving Car Kill You If it Had the Chance? A series virtual reality experiments approach the uncomfortable subject of whether human ethics should inform the ethics of self-driving cars.

What started out as a study of ethical decision making for self-driving cars turned into a study of human psychology. How do we decide, when a collision is inevitable, who or what to hit? No one wants to be confronted READ MORE

Pollution from Traffic Can Cause DNA Damage in Children Researchers compared the length of telomeres over the course of a year to see if they shortened with exposure to pollution.

Cars are everywhere. They are essential for our day to day lives, but these vehicles are a double-edged-sword. Cars emit exhaust gases, and those gases contain hydrocarbons. These molecules, as their name suggests, contain both carbon and hydrogen atoms. Hydrocarbons READ MORE

Microbial Computers: Is There Anything that Bacteria Can’t Do? Though we won’t be seeing bacteria computers on our desks any time soon, this group of researchers demonstrated that cleverly arranged bacteria operate like a rudimentary computer.

Really, is there anything that microbes can’t do?

How Do Algae Biofuels Compare to Diesel in Real Engines? Scientists put algae biodiesel blends and plain diesel fuel to the test in real engines to compare their efficiency and emissions.

Choosing the right species of algae is one of the most important first steps, they report, as it ultimately impacts the engine’s performance and amount of exhaust emissions.

The Latest Cutting-Edge Water Filtration Technique Was Inspired By Your Kidneys Both scientists and start-ups are excited about using water-filtering proteins called aquaporins to make seawater drinkable.

The latest cutting-edge water filtration technique comes from a biochemistry process that predates even dinosaurs. It involves harnessing aquaporins, a protein in cell membranes which are present in all living things.
