Researchers from Harvard have shown that thin layers of silica aerogel could warm the surface of Mars and block UV radiation while still letting visible light through. That could be enough to keep water liquid and let plants photosynthesize within a given region.

We may hear a lot about photovoltaic panels, but solar collectors are also quite useful – the devices collect heat from sunlight, which is used in applications such as the heating of homes. Now, MIT has announced a new material that could make them cheaper and more efficient than ever.

For years now, scientists have marvelled at the insulating qualities of polar bear fur, suggesting that it could inspire manmade heat-retaining materials. Well, Chinese researchers have now developed just such a substance, which reportedly outperforms real fur.

Ceramic aerogels are incredibly light and can withstand intense heat. The problem is they can be pretty brittle. Now, a team has developed a new ceramic aerogel that’s far hardier and more flexible, even after repeated exposure to wild temperature swings.

Pop bottles are one of the most common types of plastic waste, so the more ways that we can find of recycling them, the better. With that in mind, researchers at the National University of Singapore (NUS) have developed an inexpensive method of converting such bottles into a very useful aerogel.

Graphene is famous as a two-dimensional material, but to really make the most of the stuff we need to coax it back into 3D forms. Now researchers from Virginia Tech have developed a new way to 3D print graphene aerogels with a far higher resolution than previously possible.

Aerogels are among the best thermal insulators, but their cloudy appearance doesn't work for windows, one of the worst offenders for letting heat escape a building. Now, researchers at Colorado University Boulder have found a way to make them transparent, recycling a beer by-product in the process.

Scientists from the National University of Singapore have found a new use for cotton-based fabric waste – they've devised a method of converting it into an aerogel. Among other things, the ultralight material could be used to keep water bottles cold, and to control bleeding from deep wounds.

Why bother adding a layer of insulation to a brick wall, if you can just build that wall using hollow bricks that are stuffed with insulation? That's the thinking behind bricks which incorporate materials such as perlite. Now, scientists have created the best-insulating brick yet, using aerogel.

Those of us who live and seek adventure in cold weather are familiar with the various thermal technologies available. With Oros, something is different. It's lightweight, thin, and yet warmer than many other options we've owned thanks to the use of NASA-inspired aerogel.
