New chip-scale gyroscope measures rotation with high sensitivity

• Researchers developed a chip-scale optical ring-laser gyroscope measuring rotation as slow as 37 degrees per hour.
• This sensitivity could be useful for precision navigation and orientation systems, especially where GPS is unavailable.
• Scientists used AI to design proteins that can break peptide bonds, which are typically stable with a half-life of several hundred years.
• Climate scientists warn that the climate emergency is already here, highlighting the urgency of addressing Earth's 'vital signs'.
