An overwhelming majority of scientists are in agreement—and that never happens—something must change before we reach the so-called “point-of-no-return”. The onset of the industrial era (and the associated benefits) encouraged a system that pollutes our environment in search of the largest possible profits. More recently, our voices have gotten louder, and large groups of society have dedicated themselves to uncovering the solutions to these problems. Perhaps, in this regard, Mother Nature still has lessons to offer.
Some pesticides function similarly to the nerve agent sarin, and their ubiquitous use makes them a constant health hazard if unmonitored. Chemists designed a dual-microbe sensor to selectively and sensitively determine when the hazardous chemicals are nearby.
Using nanofibers to create biosensors decreases cost and wrapping them in graphene increases their conductivity.
A new way to have incompatible reactions occur in spatially separate regions of a liquid to create methanol from methane.
Skin-conforming, ultra-thin wearable medical sensors could make going to the doctor less invasive than ever before. This newly developed, “tattooable” sensor uses a newly developed material to create one of the thinnest yet.
The smaller the robot, the harder it is to carry a fuel source around. That’s where these metal-air scavengers come in. Powered by oxidizing a metal surface, they could be a useful power source for the tiny robots of the future.
Graphene’s amazing properties make it one of the most popular new materials in recent years. But what if we could improve it with an unlikely additive?
There’s a new record holder for the world’s blackest material. Learn about how randomly oriented carbon nanotubes can be used to create a coating darker than anything else ever made!
Scientists from UCSD and Compultense University developed non-invasive tools to measure gastrointestinal distress, monitoring chemical markers in real-time.
What happens when you bring DNA strands, gold nanoparticles, conformation-induced color changes, and a highly-intrusive bacterium together? A field-portable, inexpensive test for the world’s greatest bacterial threats.
We use lithium-ion batteries in our electronics every day, but getting the materials to build them isn’t very environmentally friendly. Let’s learn about a new way to recover one of these materials from burnt plants!
Modern technology is evolving at a mind-blowing rate, but what should we do with all of the obsolete hardware? Researchers are finding clever ways of recycling the old material – check it out!
Art could show the beauty of science. But art could also put science to work in real life!
Let’s learn from researchers about how origami can turn paper into a real battery!
Measuring blood sugar levels by pricking your finger is painful and inconvenient. Learn about a new wearable device that measures your glucose levels with just your sweat!
Feeling blue? The chemistry of new “smart windows” could help – with a coating that adjusts to the outside temperature and a color filter that you can switch at will, they could be the perfect mood lighting for your energy-efficient home.
Birds and other migratory animals use the Earth’s weak magnetic field to navigate, but what do they use as a compass? While previous research has uncovered some promising candidates, not until now have experiments identified a compass sensitive to fields as weak as Earth’s – DNA repair by photolyase.
With metal catalysts, we can extract electricity from CO2 – reducing carbon emissions and creating renewable energy tech at the same time! There’s just one little problem, and it’s name is hydrogen…
Catalysts are critical components of many industrial processes. Unfortunately, many promising catalysts degrade over time. Here, researchers show that some catalysts can be protected by coating them with another material.
