For all its uses, plastic is unfortunately one of our least sustainable materials. Now, scientists at Berkeley Lab have developed a way to engineer bacteria to produce raw materials that can be made into plastics that are completely recyclable.

Heating and cooling systems are among the biggest guzzlers of energy. Berkeley Lab has now developed a new technology that heats and cools by switching a material between solid and liquid states, inducing a large temperature change from a small voltage.

A simple alloy has claimed the crown for toughest material ever recorded. A team led by Berkeley Lab discovered not only its incredible toughness, but high strength and ductility that improve in colder temperatures, unlike most known materials.

The fastest internet network in the US just got a bit faster. The Energy Sciences Network has been upgraded to ESnet6, boasting a blistering bandwidth of 46 Terabits per second (Tbps). But don’t get too excited yet – it’s strictly scientists only.

Old electronics are tricky to recycle, meaning they clog up landfills while locking valuable metals away. Now scientists have demonstrated printed circuits that can be degraded on demand, returning their materials to reusable forms.

As effective as fossil fuels may be, their impact on the planet cannot be overstated. Now researchers at Berkeley Lab have coaxed bacteria into directly producing a new biofuel with an energy density significantly higher than jet fuel.

Heat is a major hurdle for electronic devices. Scientists have now found that nanowires made of a certain isotope of silicon can conduct heat 150 percent better than regular silicon, potentially leading to drastically cooler computer chips.

Berkeley Lab engineers have developed a roof coating that can keep a building warmer or cooler, depending on the weather. When it’s warm out the material will reflect sunlight and heat, but it switches itself off in winter, reducing energy use.

In a breakthrough that could open up exciting new possibilities in computing and electronics, scientists in the US have developed a two-dimensional magnetic material that is the thinnest in the world, measuring just a single atom thick.

Most plastics don’t break down easily – and when they do, they create problematic microplastic particles. A new type of compostable plastic is embedded with enzymes that, when triggered, quickly break the material down to its constituent molecules.

Scientists have now demonstrated a new type of artificial photosynthesis technology that can not only produce clean hydrogen fuel, but undergo morphological changes during use that makes it become more efficient over time.

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory have produced a material they say can selectively capture specific heavy metals from wastewater, and do so with unmatched speed and precision down to the atomic level.
