Last year marked the hottest on record, shattering previous temperature benchmarks across both land and sea. The rapid escalation – seemingly at odds with the expected cooling after coming out of a La Niña cycle – has prompted scientists to question if climate change is accelerating beyond our models' predictions 

Just eight minutes of anger can significantly impair blood vessel function and potentially increase the risk of a heart attack. A study has looked into the physiological mechanisms of how intense emotions can affect cardiovascular health.

GPS jamming continues to increase in European airspace, a concerning trend that has intensified since Russia's 2022 invasion of Ukraine. Now, attacks in Estonia have prompted one airline to completely abandon flights to the city of Tartu.

Plus: A newly discovered sensory organ in praying mantises, used specifically for tasting leaves; the possibility of carbon negative cement; and just how thick is the boundary between air and water?

Hosts Christie Taylor and Timothy Revell discuss with guests Madeline Cuff, Clare Wilson, Jeremy Hsu, and Michael Le Page. To read more about these stories, visit newscientist.com.
