A new algorithmic framework called M-TIP helps researchers determine the molecular structure of proteins and viruses from X-ray free electron laser data, which is crucial in fields like biology and medicine.
A new look inside 2,000-year-old concrete – made from volcanic ash, lime, and seawater – has provided new clues to the evolving chemistry and mineral cements that allow ancient harbor structures to withstand the test of time. The research has also inspired a hunt for the original recipe so that modern concrete manufacturers can do as the Romans did.
Researchers at the Joint BioEnergy Institute, in collaboration with the Joint Genome Institute, are reporting the first whole-genome sequence of a mutant population of Kitaake, a model variety of rice. Their high-density, high-resolution catalog of mutations facilitates the discovery of novel genes and functional elements that control diverse biological pathways.
It turns out your skin is crawling with single-celled microorganisms — and they’re not just bacteria. Researchers collaborated on a study that found that the skin microbiome also contains archaea, a type of extreme-loving microbe, and that the amount of it varies with age.
Electrostatic forces known as phosphate steering help guide the actions of an enzyme called FEN1 that is critical in DNA replication and repair, a new study finds. The findings help explain how FEN1 distinguishes which strands of DNA to target, revealing key details on a vital process in healthy cells, and providing new directions for cancer treatment research.
A global hunt for the universe’s missing matter is underway, and this autumn everyone is invited to join in. On and around Oct. 31, events around the world will celebrate the hunt for the universe’s unseen “dark matter.” Events will engage the public in discussions about dark matter, and about the many experiments that seek to solve its mysteries.
The semiconductors can emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers, and could usher in a new generation of high-definition displays, optoelectronic devices, photodetectors, and more.The work could challenge quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light.
A proposed new method for sending acoustic waves through water could dramatically increase communication speeds for scuba divers, deep-sea robots, and remote ocean monitors. The dynamic rotation generated as waves travel enabled more channels onto a single frequency, effectively increasing the amount of information capable of being transmitted.
Berkeley Lab and Michigan State University researchers are providing the clearest view yet of an intact bacterial microcompartment, revealing at atomic-level resolution the structure and assembly of the organelle’s protein shell. This work could benefit bioenergy and pathogenesis research and new methods for bacteria bioengineering.
In high school, Katie Dunne dreamed of becoming a physicist but didn’t know anyone who worked in science. This summer, as a Berkeley Lab Undergraduate Research intern, she is working with her mentor Maurice Garcia-Sciveres to build prototype integrated circuit test systems for ATLAS as part of the High Luminosity Large Hadron Collider Project.
