New research into word comprehension in dogs suggests that with training and special equipment, man’s best friend can in fact understand specific words and reply. Senior author Federico Rossano is a cognitive scientist at UC San Diego and joins Living on Earth’s Steve Curwood to explain why motivation appears to be one of the most important factors driving this ability for dogs to converse in human speech.

Physical disabilities can make getting outside more challenging, but adaptive devices and accessible trails can transform lives. Producer El Wilson, who has cerebral palsy, and producer Jenni Doering test an offroad wheelchair and meet a woman who has been able to reclaim the joy and freedom of hiking since becoming disabled.

New research published in Nature suggests that initial death tolls only account for a tiny fraction of the mortality that can be linked to hurricanes. On average, each tropical storm or hurricane contributes to 7,000 to 11,000 excess deaths as long as 15 years afterwards. Lead author Rachel Young of UC Berkeley joins Host Paloma Beltran to explain how societal disruptions can bring these long-term effects.

Unusually warm waters in the Gulf of Mexico helped fuel the rapid intensification of Hurricanes Helene and Milton. Meteorologist Sean Sublette explains to Host Jenni Doering that as humans continue to pump climate-warming greenhouse gases into the atmosphere, we are loading the dice for stronger storms.
