Online news editor David Grimm shares stories on evidence for the earth being hit by supernovae, record-breaking xenotransplantation, and winning friends and influencing people with human sacrifice. Staff news writer Jocelyn Kaiser joins host Sarah Crespi to discuss how small membrane-bound packets called “exosomes” might pave the way for cancer cells to move into new territory in the body.

Randomizing the news for science, transplanting genetically engineered skin, and the ethics of experimental brain implants

By traffic.omny.fm
Published On :: Thu, 09 Nov 2017 14:00:00 -0500

This week we hear stories on what to do with experimental brain implants after a study is over, how gene therapy gave a second skin to a boy with a rare epidermal disease, and how bone markings thought to be evidence for early hominid tool use may have been crocodile bites instead, with Online News Editor Catherine Matacic. Sarah Crespi interviews Gary King about his new experiment to bring fresh data to the age-old question of how the news media influences the public. Are journalists setting the agenda or following the crowd? How can you know if a news story makes a ripple in a sea of online information? In a powerful study, King’s group was able to publish randomized stories on 48 small and medium sized news sites in the United States and then track the results. Listen to previous podcasts.

Increasing transparency in animal research to sway public opinion, and a reaching a plateau in human mortality

By traffic.omny.fm
Published On :: Thu, 28 Jun 2018 14:00:00 -0400

Public opinion on the morality of animal research is on the downswing in the United States. But some researchers think letting the public know more about how animals are used in experiments might turn things around. Online News Editor David Grimm joins Sarah Crespi to talk about these efforts. Sarah also talks Ken Wachter of the University of California, Berkeley about his group’s careful analysis of data from all living Italians born 105 or more years before the study. It turns out the risk of dying does not continue to accelerate with age, but actually plateaus around the age of 105. What does this mean for attempts to increase human lifespan? In this month’s book segment, Jen Golbeck talks with Simon Winchester about his book The Perfectionists: How Precision Engineers Created the Modern World.

Liquid water on Mars, athletic performance in transgender women, and the lost colony of Roanoke

By traffic.omny.fm
Published On :: Thu, 26 Jul 2018 14:00:00 -0400

Billions of years ago, Mars probably hosted many water features: streams, rivers, gullies, etc. But until recently, water detected on the Red Planet was either locked up in ice or flitting about as a gas in the atmosphere. Now, researchers analyzing radar data from the Mars Express mission have found evidence for an enormous salty lake under the southern polar ice cap of Mars. Daniel Clery joins host Sarah Crespi to discuss how the water was found and how it can still be liquid—despite temperatures and pressures typically inhospitable to water in its liquid form. Read the research. Sarah also talks with science journalist Katherine Kornei about her story on changing athletic performance after gender transition. The feature profiles researcher Joanna Harper on the work she has done to understand the impacts of hormone replacement therapy and testosterone levels in transgender women involved in running and other sports. It turns out within a year of beginning hormone replacement therapy, transgender women plateau at their new performance level and stay in a similar rank with respect to the top performers in the sport. Her work has influenced sports oversight bodies like the International Olympic Committee. In this month’s book segment, Jen Golbeck interviews Andrew Lawler about his book The Secret Token: Myth, Obsession, and the Search for the Lost Colony of Roanoke. Next month’s book will be The Book of Why: The New Science of Cause and Effect by Judea Pearl and Dana Mackenzie.

Creating chimeras for organ transplants and how bats switch between their eyes and ears on the wing

By traffic.omny.fm
Published On :: Thu, 27 Jun 2019 14:45:00 -0400

Researchers have been making animal embryos from two different species, so-called “chimeras,” for years, by introducing stem cells from one species into a very early embryo of another species. The ultimate goal is to coax the foreign cells into forming an organ for transplantation. But questions abound: Can evolutionarily distant animals, like pigs and humans, be mixed together to produce such organs? Or could species closely related to us, like chimps and macaques, stand in for tests with human cells? Staff Writer Kelly Servick joins host Sarah Crespi to discuss the research, the regulations, and the growing ethical debate. Also this week, Sarah talks with Yossi Yovel of the School of Zoology and the Sagol School of Neuroscience at Tel Aviv University in Israel about his work on sensory integration in bats. Writing in Science Advances, he and his colleagues show through several clever experiments when bats switch between echolocation and vision. Yossi and Sarah discuss how these trade-offs in bats can inform larger questions about our own perception. For our monthly books segment, Science books editor Valerie Thompson talks with Lucy Jones of the Seismological Laboratory at the California Institute of Technology in Pasadena about a song she created, based on 130 years of temperature data, for an instrument called the “viola de gamba.” Read more on the Books et al. blog.

Where our microbiome came from, and how our farming and hunting ancestors transformed the world

By traffic.omny.fm
Published On :: Thu, 29 Aug 2019 14:45:00 -0400

Micro-organisms live inside everything from the human gut to coral—but where do they come from? Host Meagan Cantwell talks to Staff Writer Elizabeth Pennisi about the first comprehensive survey of microbes in Hawaii’s Waimea Valley, which revealed that plants and animals get their unique microbiomes from organisms below them in the food chain or the wider environment. Going global, Meagan then speaks with Erle Ellis, professor of geography and environmental science at the University of Maryland, Baltimore County, about a project that aggregated the expertise of more than 250 archaeologists to map human land use over the past 10,000 years. This detailed map will help fine-tune climate models. This week’s episode was edited by Podigy.

A loss in binding affinity at A147T relative to WT TSPO is seen with most TSPO ligands. Provision of hydrogen-bonding opportunities on indole carboxamides rescues this loss in affinity.
