On this week’s podcast, how the molecular structure of tooth enamel may impact decay, adhesive patches to heal heart attacks, and a mysterious planetary core from a half-formed gas giant.
In this episode:
00:46 Unravelling tooth enamel
Researchers have been looking into the structure and composition of enamel in an effort to better understand tooth decay. Research Article: DeRocher et al.
07:02 Research Highlights
An adhesive patch to help heal heart-attacks, and a new technique to inspect the structure of 2D ‘wonder materials’. Research Highlight: A healing patch holds tight to a beating heart; Research Highlight: A snapshot shows off super-material only two atoms thick
09:21 Unusual planet
In the region close to stars known as the ‘hot Neptune desert’ planets of Neptune’s size are rarely found, but this week scientists have uncovered one and are trying to untangle its mysteries. Research Article: Armstrong et al.
14:52 Briefing Chat
We take a look at some highlights from the Nature Briefing. This time we talk about the pitfalls of using CRISPR in human embryos, and renaming of moon craters inadvertently named after Nazi scientists. Nature News: CRISPR gene editing in human embryos wreaks chromosomal mayhem; Prospect Magazine: Astronomers unknowingly dedicated moon craters to Nazis. Will the next historical reckoning be at cosmic level?
This week, crafting an artificial eye with the benefits of a human’s, and understanding how disk-galaxies formed by peering back in time.
Listen to the latest from the world of science, brought to you by Benjamin Thompson and Nick Howe. This week, observations of objects orbiting a black hole, and rethinking how we measure screen-time.
During this decade, as in previous decades, Caltech scientists and engineers reinvented the landscape of scientific endeavor: from the first detection of gravitational waves and the discovery of evidence for a ninth planet in the solar system; to bold missions to explore and understand the solar system; to the development of new methods to see inside the body and the brain and understand the universe around us; to the invention of devices to improve human health, some taking inspiration from nature; to the initiation of a transformative new effort to support research into the most pressing challenges in environmental sustainability.
Though the brain orchestrates how we experience the world, many questions remain about its complex workings. During the past 10 years, Caltech scientists have discovered how the brain recognizes 
As modern technology advances, so do the possibilities for treating medical conditions that were previously considered untreatable. Caltech researchers used an electrode array to help a paralyzed patient
