01:28 Inflammation’s role in memory
How memories are stored is an ongoing question in neuroscience. Now researchers have found an inflammatory pathway that responds to DNA damage in neurons has a key role in the persistence of memories. How this pathway helps memories persist is unclear, but the researchers suggest that how the DNA damage is repaired may play a role. As inflammation in the brain is often associated with disease, the team were surprised by this finding, which they hope will help uncover ways to better preserve our memories, especially in the face of neurodegenerative disorders.

11:14 How melting ice is affecting global timekeeping
Due to variations in the speed of Earth’s rotation, the length of a day is rarely exactly 24 hours. By calculating the strength of the different factors affecting this, a researcher has shown that while Earth’s rotation is overall speeding up, this effect is being tempered by the melting of the polar ice caps. As global time kept by atomic clocks occasionally has to be altered to match Earth’s rotation, human-induced climate change may delay plans to add a negative leap-second to ensure the two align.
