    Laboratory Research without a PhD, Rosa Hoyle
    "Forget about what you think people are thinking about you, and just try your hardest. That's the wonderful thing about science. People respect hard work and your results talk a lot more than your appearance... What people really care about in science is what you're publishing, what you're giving to the scientific community..." -Rosa Hoyle Rosa's LinkedIn Profile The laboratory Rosa works in is Dr. David Holtzman's Neuroscience Lab which is studying Alzheimers disease. Here are a few of the major items we discussed: Alzheimer's Disease Antibodies Plaques & tangles Ted Talk about Alzheimers that Mel mentioned: click here

    Envirothon - Environmental resources research competition for highschoolers Related Headline: Sea level rise in 20th century was fastest in 3,000 years, Rutgers-led study finds Rutgers Department website where Jennifer is completing a PhD   Research concepts discussed with Jennifer on episode 26 Proxy - "In paleoclimatology, or the study of past climates, scientists use what is known as proxy data to reconstruct past climate conditions. These proxy data are preserved physical characteristics of the environment that can stand in for direct measurements. Paleoclimatologists gather proxy data from natural recorders of climate variability such as tree rings, ice cores, fossil pollen, ocean sediments, corals and historical data. By analyzing records taken from these and other proxy sources, scientists can extend our understanding of climate far beyond the instrumental record." Foraminifera are a species that are used as proxy indicators for scientists like Jennifer to study historic sea level changes. "Foraminifera (forams for short) are single-celled protists with shells. Their shells are also referred to as tests because in some forms the protoplasm covers the exterior of the shell. The shells are commonly divided into chambers which are added during growth, though the simplest forms are open tubes or hollow spheres. Depending on the species, the shell may be made of organic compounds, sand grains and other particles cemented together, or crystalline calcite." You can read a peer-reviewed article about that here. Sediment Stratigraphy - "The branch of geology that seeks to understand the geometric relationships between different rock layers (called strata), and to interpret the history represented by these rock layers." Marsh - "A marsh is a type of wetland, an area of land where water covers ground for long periods of time. Unlike swamps, which are dominated by trees, marshes are usually treeless and dominated by grasses and other herbaceous plants. Herbaceous plants have no woody stem above ground, and they grow and die back on a regular cycle. Herbaceous plants can be annuals (which grow anew every year), biennials (which take two years to complete their life cycle), or perennials (which take more than two years to complete their life cycle.) Marsh grasses and other herbaceous plants grow in the waterlogged but rich soil deposited by rivers. The plants roots bind to the muddy soil and slow the water flow, encouraging the spread of the marsh. These watery pastures are rich in biodiversity. There are three types of marshes: tidal salt marshes, tidal freshwater marshes, and inland freshwater marshes. Marshes are also common in deltas, where rivers empty into a larger body of water. Although all are waterlogged and dominated by herbaceous plants, they each have unique ecosystems." Glacial isostatic adjustment - the ongoing movement of land once burdened by ice-age glaciers.

     -- How are scientists able to "go back in time" to study how the environment was on earth many years ago?
    Ocean floor core sampling Tree rings as a way to understand the environment in years past (Dendrochronology) - This audio clip is an excellent explanation of how scientists use tree rings in combination other data to perform dating: listen here Ice corps from Greenland and Antarctica Corals also have annual layers they grow through time. You can use these similarly We also spoke with Dr. Holmes in episode 14 about core sampling! How do scientists date this stuff? Radiometric clocks! How carbon dating works (must click through all pages)! Ice core sample dating works and what the heck is ferne? Now Corals... How do we date corals?  More core sampling!

    Dr. Joanna Haigh has been Co-Director of the Grantham Institute at Imperial College since 2014. For the previous 5 years she was Head of the Department of Physics. Joanna's scientific interests include radiative transfer in the atmosphere, climate modelling, radiative forcing of climate change and the influence of solar irradiance variability on climate. She has published widely on these topics in the scientific literature and also contributed to numerous items to the written and broadcast popular media. She has been President of the Royal Meteorological Society, Editor of Quarterly Journal of the Royal Meteorological Society and of the Journal of Atmospheric Sciences, a Lead Author on the Intergovernmental Panel on Climate Change and acted on many UK and international panels.  She is a Fellow of the Royal Society, the Institute of Physics, the City & Guilds and the Royal Meteorological Society and an Honorary Fellow of Somerville College Oxford.  She was awarded the Institute of Physics Charles Chree Medal and Prize 2004, the Royal Meteorological Society Adrian Gill Prize 2010 and appointed CBE in the 2013 New Years Honours.

Customer Reviews

cnaughto ,

STEMxm is awesome!

STEMxm is amazing. It gives indepth interviews with important, minority scientists and engineers in a way that is interesting and fun. The host makes sure that the participants break down their technical terminology so everyone can understand and motivate others to pursue STEM careers.

Matilda 13 ,

Fun and Informative

I learn interesting facts and feel like I have personally met each of the people that Mel interviews in her podcasts. I realize the target audience is young adults and teens considering the STEM professions; however, anyone can gain insightful information from listening in. Fantastic resouce for those in considering their options for a career and those who might want a change.

Jason Love ,

I Love Science & this Podcast

It is interesting to hear the stories of how each guess got into their career.
Even more interesting is all the cool things they work on.
