Using Tiny Organisms to Unlock Big Environmental Mysteries

When you hear about the biological processes that influence climate and the environment, such as carbon fixation or nitrogen recycling, it’s easy to think of them as abstract and incomprehensibly large-scale phenomena. Yet parts of these planet-wide processes are actually driven by the tangible actions of organisms at every scale of life, beginning at the smallest: the microorganisms living in the air, soil, and water. And now Berkeley Lab researchers have made it easier than ever to study these microbial communities by creating an optimized DNA analysis technique.

How to Catch a Magnetic Monopole in the Act

A research team led by Berkeley Lab has created a nanoscale “playground” on a chip that simulates the formation of exotic magnetic particles called “monopoles.” The study could unlock the secrets to ever-smaller, more powerful memory devices, microelectronics, and next-generation hard drives that employ the power of magnetic spin to store data.

The electron shuttling process is coupled with proton pumps that power ATP formation by ATP synthase.  An electron can flow linearly to power NADPH formation or it can be cycled between photosystem I and NDH to boost ATP synthesis.

New Molecular Blueprint Advances Our Understanding of Photosynthesis

Researchers at Berkeley Lab have used one of the most advanced microscopes in the world to reveal the structure of a large protein complex crucial to photosynthesis, the process by which plants convert sunlight into cellular energy. The finding, published in the journal Nature, will allow scientists to explore, for the first time, how the complex functions and could have implications for the production of a variety of bioproducts, including plastic alternatives and biofuels.

Preparing for a New Tool to Study the ‘Glue That Binds Us All’

For several decades, the nuclear science community has been calling for a new type of particle collider to pursue – in the words of one report – “a new experimental quest to study the glue that binds us all.” This glue is responsible for most of the visible universe’s matter and mass. To learn about this glue, scientists are proposing a unique, high-energy collider that smashes accelerated electrons, which carry a negative charge, into charged atomic nuclei or protons, which carry a positive charge.
