Just Forget It We may curse our forgetfulness, but the process is intimately entwined with our ability to maintain healthy memories, writes neuroscientist Lisa Genova in a new book, reviewed by David Kortava in TheNew Yorker. The brain appears almost "designed to forget information" on a cellular level. Dalmeet Singh Chawla described how the neuroscience of deleting memories balances the processes that create them for Quanta in 2018.
Antimatter Needs to Chill Researchers at CERN have developed new laser cooling systems that will let them scrutinize the behavior of antimatter in new ways and search for elusive differences from normal matter, Adam Rogers reports for WIRED. Another recent experiment hints that nature may discriminate between neutrinos and antineutrinos, which could start to explain why matter came to rule the visible universe, Natalie Wolchover reported for Quanta last year.
