India’s EV Drive Will Boost Power Utilities, Increase Energy Security

India is pushing hard to electrify its automobile market, aiming to sell only electric vehicles (EVs) by 2030. But what impact will that shift have on the country’s utilities and the grid? A new report by scientists at Berkeley Lab has found that the prospective EV expansion will deliver economic benefits, help integrate renewable energy, and significantly reduce imports of foreign oil.

Researchers ID New Mechanism for Keeping DNA Protein in Line

Electrostatic forces known as phosphate steering help guide the actions of an enzyme called FEN1 that is critical in DNA replication and repair, finds a new study led by Berkeley Lab researchers. The findings help explain how FEN1 distinguishes which strands of DNA to target, revealing key details about a vital process in healthy cells as well as providing new directions for cancer treatment research.

Could This Strategy Bring High-Speed Communications to the Deep Sea?

Berkeley Lab researchers are proposing a new method for sending acoustic waves through water that could dramatically increase communication speeds for scuba divers, deep sea robots, and remote ocean monitors. By taking advantage of the dynamic rotation generated as waves travel, the researchers were able to pack more channels onto a single frequency, effectively increasing the amount of information capable of being transmitted.
