Carbon

Much of the heat and carbon produced by humans is absorbed by the ocean. New research has shed light on the role that underwater waves play in moving that heat and carbon around our oceans, an important factor in predicting climate change.
-
Bacteria often get a bad rap, but in many cases they’re helpful little critters. Engineers have now developed a protective coating for buildings that’s loaded with bacteria, which absorb CO2 to produce a barrier against erosion by the elements.
-
The amount of single-use plastics the world disposed of during the pandemic continues to be a huge environmental headache. A clever new upcycling method, though, takes the trash and turns it into one increasingly lucrative piece of tech, carbon dots.
-
Carbon nanotubes have found use in everything from smart bandages to more efficient solar cells. Now, scientists at the University of Wisconsin-Madison have used them in a helmet lining foam that offers better impact protection than regular foams.
-
Life on Earth has persisted for billions of years through many extreme climate events. MIT scientists have analyzed 66 million years of climate data and found a stabilizing mechanism for global temperatures that plays out on large timescales.

As microplastics pollution and potable water scarcity both worsen, it's becoming increasingly important to find efficient ways of filtering and desalinating seawater. A new aerogel definitely holds some promise, and it's made from egg whites.
-
Tree rings can preserve a snapshot of the Earth throughout the tree's life. Now Australian scientists analyzing these records have found evidence of huge radiation storms that periodically bathe the planet – and their origin remains a mystery.
-
Engineers at EPFL have inserted carbon nanotubes into photosynthetic bacteria, greatly improving their electrical output. They even pass these nanotubes down to their offspring when they divide, through what the team calls “inherited nanobionics.”
-
We're seeing a growing emphasis on direct air capture technology in our efforts to combat climate change, and an interesting new take on this technology could see it put to use on railways around the world.
-
Engineers have demonstrated a quantum integrated circuit made of just a few atoms. By precisely controlling the quantum states of the atoms, the processor can simulate the structure and properties of molecules, which could unlock new materials.
-
Carbon capture could be an important tool to fight climate change. Researchers have now developed a new compound that can reportedly remove carbon dioxide from ambient air with 99 percent efficiency and at least twice as fast as existing systems.
-
Engineers in the US and Mexico have developed a way to use soot from emissions to improve solar thermal devices. The coatings are not only cheaper to produce but more efficient than using materials like graphene, while reducing pollution.
