Oak Ridge National Laboratory researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric vehicles and consumer electronics.

The new class called NFA, which stands for nickel-, iron-and aluminum-based cathode, is a derivative of lithium nickelate and can be used to make the positive electrode of a lithium-ion battery. These novel cathodes are designed to be fast charging, energy dense, cost effective, and longer lasting.

With the rise in the production of portable electronics and electric vehicles throughout the world, are in high demand. According to Ilias Belharouak, ORNL’s scientist leading the NFA research and development, more than 100 million electric vehicles are anticipated to be on the road by 2030. Cobalt is a metal currently needed for the cathode which makes up the significant portion of a lithium-ion battery’s cost.

Old-time solutions are reappearing as we seek to become a zero-emissions society.

How can the agriculture industry reduce the amount of methane released when cows burp? It’s been a struggle for scientists and policymakers. A new method in which farmers feed seaweed to cows — needing to incorporate only about 0.2% of the total feed intake — indicates that methane levels can be reduced by 98%. It’s a real breakthrough, as most existing solutions cut methane only by about 20% to 30%.

Dr. Steve Horvath, a professor of genetics and biostatistics at UCLA, has found a way to measure biological aging – a type of “clock” – based on the methylation pattern of an organism’s genome. Methylations are biochemical processes that modify the activity of a DNA segment without changing its sequence – a type of epigenetic change. This video primer explains the basics of epigenetic clocks, the topic of our interview with Dr. Steve Horvath, coming soon!

Episode highlights:
• 00:00:09 — A person’s risk of disease is more dependent on their biological age than their chronological age.
• 00:00:09 — Epigenetics refers to processes that can affect gene expression without changing the DNA sequence. Methylation is a type of epigenetic change that occurs over a lifetime in a predictable way and can be used to measure biological age.
• 00:01:17 — The Horvath clock can accurately predict a person’s chronological age based on only the epigenetic information in their blood.
• 00:01:54 — The GrimAge clock can predict the risk and time of onset of cancer, heart disease, and death.
• 00:02:19 — Certain drugs can reverse a person’s epigenetic age, but the effects on biological age are unknown.
• 00:03:09 — The discovery of an anti-aging drug is on the horizon.
