Dog sniff out Post-Traumatic Stress Disorder (PTSD) episodes in research: Human breath odor can warn trained service dogs of oncoming flashbacks in people who have PTSD, according to a study published in Frontiers in Allergy, making it possible to stop the episodes earlier and more effectively. PTSD service dogs already predict episodes from cues like fist-clenching or elevated respiration and heart rates, and the successful dogs in the study seem to respond to separate olfactory biomarkers, one tied to human participants’ self-reported shame and another to self-reported anxiety, says researcher Laura Kiiroja.

Menopause may help whale species survive: Female short-finned pilot whales, orcas, false killer whales, narwhals and beluga whales all experience menopause and live an average of 40 years longer than similar-size females of other whale species, researchers reported in the journal Nature. Female toothed whales are known to share food and guide their pods to food sources, suggesting that menopause enables the species to help ensure their families’ survival without continuing to reproduce, said researcher Darren Croft, Executive Director of the Center for Whale Research.

Cool scientist “humbled” by Girl Scouts: The Girl Scouts of San Diego named Suzie Alarcón one of this year’s Cool Women, an honor that “humbled and wowed and inspired” Alarcón, who is Director of the La Jolla Institute for Immunology’s Next Generation Sequencing Core. Alarcón led the team that won the grand XPrize for its COVID-19 test and is the founder of genome sequencing firm UGenomics. “I don’t know if I can be an inspiration to [young girls], but I can show them they can be complicated people and get to something that suits you in your career,” Alarcón said.

Massive dog research project has implications for humans: The “Dog Aging Project”, now in its fourth year, has collected data from 47,000 dog owners acting as volunteer scientists, with the information gathered ranging from tracking the amount eaten and other activities through more detailed environmental monitoring through wearing silicone tags that are later assessed by mass spectrometry. “A lot of the environmental factors that influence the health of dogs also affect humans in a very similar way, because our genetic structure is so similar,” said Audrey Ruple, a Veterinary Professor who also serves on the project’s board.

GI leaks detected by implantable device in pigs and rats: After gastrointestinal surgery, patients are at risk of developing leaks that can cause infections; however, a new implantable device was able to detect these leaks in pigs and rats, researchers reported in the journal, Science. The BioSUM device contains a pH-sensitive gel that reacts to leaks from the stomach or other organs, causing the gel to expand and push metal discs in the device further apart, which can be detected by ultrasound.
