Double dipping in an NIH loan repayment program, and using undersea cables as seismic sensors

The National Institutes of Health’s largest loan repayment program was conceived to help scientists pay off school debts without relying on industry funding. But a close examination of the program by investigative correspondent Charles Piller has revealed that many participants are taking money from the government to repay their loans, while at the same time taking payments from pharmaceutical companies. Piller joins Host Sarah Crespi to talk about the steps he took to uncover this double dipping and why ethicists say this a conflict of interest.   Sarah also talks with Nate Lindsey, a Ph.D. candidate at the University of California, Berkeley, about turning a 50-kilometer undersea fiber optic cable designed to move data into a sensor for activity in the ocean and the land underneath. During a 4-day test in Monterey Bay, California, the cable detected earthquakes, faults, waves, and even ocean-going storms. For this month’s books segment, Kiki Sandford talks with Dan Hooper about his book At the Edge of Time: Exploring the Mysteries of Our Universe’s First Seconds.   You can find more books segments on the Books et al. blog.   This week’s episode was edited by Podigy.   Ads on this week’s show: McDonalds; Salk’s Where Cures Begin podcast   Download the transcript (PDF) Listen to previous podcasts.   About the Science Podcast

Debating lab monkey retirement, and visiting a near-Earth asteroid

After their life as research subjects, what happens to lab monkeys? Some are euthanized to complete the research, others switch to new research projects, and some retire from lab life. Should they retire in place—in the same lab under the care of the same custodians—or should they be sent to retirement home–like sanctuaries? Online News Editor David Grimm joins host Sarah Crespi to discuss recently penned legislation that pushes for monkey retirements and a new collaboration between universities and sanctuaries to create a retirement pipeline for these primates. Sarah also talks with Dante Lauretta, principal investigator for NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) and a professor at the University of Arizona in Tucson, about the latest news from the asteroid Bennu. Within 1 week of beginning its orbit of the asteroid, OSIRIS-REx was able to send back surprising images of the asteroid ejecting material. It’s extremely rocky surface also took researchers by surprise and forced a recalculation of the sample return portion of the craft’s mission. This week’s episode was edited by Podigy.

Areas to watch in 2020, and how carnivorous plants evolved impressive traps

We start our first episode of the new year looking at future trends in policy and research with host Joel Goldberg and several Science News writers. Jeffrey Mervis discusses upcoming policy changes, Kelly Servick gives a rundown of areas to watch in the life sciences, and Ann Gibbons talks about potential advances in ancient proteins and DNA. In research news, host Meagan Cantwell talks with Beatriz Pinto-Goncalves, a postdoctoral researcher at the John Innes Centre, about carnivorous plant traps. Through understanding the mechanisms that create these traps, Pinto-Goncalves and colleagues elucidate what this could mean for how they emerged in the evolutionary history of plants.

Squeezing two people into an MRI machine, and deciding between what’s reasonable and what’s rational

Getting into an MRI machine can be a tight fit for just one person. Now, researchers interested in studying face-to-face interactions are attempting to squeeze a whole other person into the same tube, while taking functional MRI (fMRI) measurements. Staff Writer Kelly Servick joins host Sarah Crespi to talk about the kinds of questions simultaneous fMRIs might answer. Also this week, Sarah talks with Igor Grossman, director of the Wisdom and Culture Lab at the University of Waterloo, about his group’s Science Advances paper on public perceptions of the difference between something being rational and something being reasonable.

Researchers flouting clinical reporting rules, and linking gut microbes to heart disease and diabetes

Though a law requiring clinical trial results reporting has been on the books for decades, many researchers have been slow to comply. Now, 2 years after the law was sharpened with higher penalties for noncompliance, investigative correspondent Charles Piller took a look at the results. He talks with host Sarah Crespi about the investigation and a surprising lack of compliance and enforcement. Also this week, Sarah talks with Brett Finlay, a microbiologist at the University Of British Columbia, Vancouver, about an Insight in this week’s issue that aims to connect the dots between noncommunicable diseases like heart disease, diabetes, and cancer and the microbes that live in our guts. Could these diseases actually spread through our microbiomes? This week’s episode was edited by Podigy. Listen to previous podcasts. About the Science Podcast Download a transcript (PDF).

A cryo–electron microscope accessible to the masses, and tracing the genetics of schizophrenia

Structural biologists rejoiced when cryo–electron microscopy, a technique to generate highly detailed models of biomolecules, emerged. But years after its release, researchers still face long queues to access these machines. Science’s European News Editor Eric Hand walks host Meagan Cantwell through the journey of a group of researchers to create a cheaper, more accessible alternative. Also this week, host Joel Goldberg speaks with psychiatrist and researcher Goodman Sibeko, who worked with the Xhosa people of South Africa to help illuminate genetic details of schizophrenia. Though scientists have examined this subject among Western populations, much less is known about the underlying genetics of people native to Africa.

Brickmaking bacteria and solar cells that turn ‘waste’ heat into electricity

On this week’s show, Staff Writer Robert F. Service talks with host Sarah Crespi about manipulating microbes to make them produce building materials like bricks—and walls that can take toxins out of the air. Sarah also talks with Paul Davids, principal member of the technical staff in applied photonics & microsystems at Sandia National Laboratories, about an innovation in converting waste heat to electricity that uses similar materials to solar cells but depends on quantum tunneling. And in a bonus segment, producer Meagan Cantwell talks with Online News Editor David Grimm on stage at the AAAS annual meeting in Seattle. They discuss how wildfires can harm your lungs, crime rates in so-called sanctuary states, and how factors such as your gender and country of origin influence how much trust you put in science.

Biobased Polyols for Industrial Polymers


 
The replacement of polyols synthesized from petrochemical by polyols originating from natural products, notably from vegetable oils and animal fats, has been the subject of research projects for a number of decades.

Very recently, however, the polymers industry has intensified its efforts to include the “green products”, such as biobased polyols, in applications already available in the market. Examples of such applications include polyurethane foams
