Science Podcasts: CRISPR & Immunotherapy, Ice Age Cave Art Dated With Wasp Nests (ScienceMag)

scimag_pc_logo_120_120 (2)On this week’s show, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to talk about Science paper that combines two hot areas of research—CRISPR gene editing and immunotherapy for cancer—and tests it in patients.

Sarah also talks with Damien Finch, a Ph.D. candidate in the School of Earth Sciences at the University of Melbourne, about the Kimberly region of Australia and dating its ice age cave paintings using charcoal from nearby wasp nests.

Research: CalTech Scientists Target Cancer Cells With Ultrasound

From a CalTech news article (February 4, 2020):

Ultrasonic-Cancer-Treat-14-50.2e16d0ba.fill-310x200-c100The hope, Lee says, is that ultrasound will kill cancer cells in a specific way that will also engage the immune system and arouse it to attack any cancer cells remaining after the treatment.

A new technique could offer a targeted approach to fighting cancer: low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed.

CalTech logoUltrasound waves—sound waves with frequencies higher than humans can hear—have been used as a cancer treatment before, albeit in a broad-brush approach: high-intensity bursts of ultrasound can heat up tissue, killing cancer and normal cells in a target area. Now, scientists and engineers are exploring the use of low-intensity pulsed ultrasound (LIPUS) in an effort to create a more selective treatment.

A study describing the effectiveness of the new approach in cell models was published in Applied Physics Letters on January 7. The researchers behind the work caution that it is still preliminary—it still has not been tested in a live animal let alone in a human, and there remain several key challenges to address—but the results so far are promising.

Science Podcasts: Low-Cost Cryo-Electron Microscopes & Genetic Roots Of Schizophrenia

Science Magazine PodcastsStructural 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.

Cryo-Electron Microscopes

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.

Science And Technology: “3D Printing With Living Organisms” (MIT Video)

A method for printing 3D objects that can control living organisms in predicable ways has been developed by an interdisciplinary team of researchers at MIT and elsewhere. This technique may lead to 3D printing of biomedical tools that can be customized to fit the physical body and biomarkers of its users.
