President L. Rafael Reif joins Alan Alda on his podcast “Clear + Vivid” to discuss the need for increased American investment in fundamental research and development.

Prof. Max Shulaker has fabricated the first foundry-built silicon wafer, a monolithic 3D carbon nanotube integrated circuit, reports Samuel K. Moore for IEEE Spectrum. “We’ve completely reinvented how we manufacture this technology,” explains Shulaker, “transforming it from a technology that only worked in our academic labs to a technology that can and is already today working inside a commercial fabrication facility within a U.S. foundry.”

A study by Prof. Dan Rothman finds that increasing greenhouse gas emission rates could trigger a mass extinction in the ocean, reports Priya Shukla for Forbes. Shukla writes that Rothman found if a certain carbon threshold “is breached, it would take tens of thousands of years for the oceans to return to their original unperturbable state.”

MIT researchers have developed artificial muscles that can stretch more than 1,000 percent of their size and lift more than 650 times their weight, reports Sid Perkins for Scientific American. The new fibers could have applications in robotics and prosthetic devices, Perkins explains, and “work more like real muscles: they do work by pulling on or lifting objects.”

MIT researchers have developed a new method for potentially increasing solar cell efficiency beyond the theoretical limit, reports Daniel Oberhaus for Wired. “What’s cool here is that this is a fundamentally different approach from traditional photovoltaics,” says Joseph Berry of the National Renewable Energy Laboratory.

A study by Prof. Daniel Rothman finds that if carbon emissions exceed a critical threshold, it could lead to a mass extinction, reports Martin Finucane for The Boston Globe. "We should limit carbon dioxide emissions,” says Rothman. “The carbon cycle is a non-linear system, and if you perturb it, surprising things may happen.”

TechCrunch reporter Darrell Etherington writes that MIT researchers have developed a system that can predict a perso's trajectory. The tool could allow “robots that typically freeze in the face of anything even vaguely resembling a person walking in their path to continue to operate and move around the flow of human foot traffic."

MIT researchers have developed a new system to 3-D print scaffolding for biological cultures, making it possible to grow uniform cells with specific functions, reports The Economist. “This discovery could help those trying to find ways of encouraging stem cells to generate tissue and organs for transplant.”

Inside Higher Ed reporter Lindsay McKenzie writes that a new AI system developed by MIT researchers to summarize the findings of technical scientific papers could “be used in the near future to tackle a long-standing problem for scientists -- how to keep up with the latest research.”

Bloomberg News reporter Carol Massar spotlights how MIT researchers have developed a robot that can identify and sort recyclables. “The system includes a soft Teflon hand that uses tactile sensors to detect the size of an object and the pressure needed to grasp it,” Massar reports. “From there it can determine if it’s made of metal, paper or plastic.”

Boston Globe reporter Laura Krantz visits MIT’s Haystack Observatory to learn more about the place where scientists played a key role in developing the first image of a black hole and created a supercomputer used to compile the image. Krantz notes that researchers at Haystack also study the Earth, not-far-away planets, and stars, and are creating devices to track the decay of icebergs.

Scientific American reporter Jeremy Hsu highlights how CSAIL researchers have developed a robot that can automatically sort recycling. The robot “uses soft Teflon ‘fingers,’ which have fingertip sensors to detect object size and stiffness,” Hsu explains.

Sky and Telescope editor Monica Young speaks with WBUR about how scientists from the LIGO and Virgo gravitational wave observatories, including MIT researchers, may have detected a black hole colliding with a neutron star. Young explains that upgrades made to both observatories should enable investigation of not only individual cosmic events, but also the study of neutron stars and black holes as populations.

Adrian Cho of Science magazine writes that the possible black hole-neutron star merger spotted by LIGO and Virgo would be a “gem for scientists,” but work remains to confirm the signal. Prof. Salvatore Vitale, a LIGO member from MIT, tells Cho: “If you ask me, ‘Would you bet a coffee, your car, or your house on this?’ I would say, ‘I’d bet your car.’”

Gizmodo reporter Ryan Mandelbaum explores the five potential gravitational wave detections made by the LIGO and Virgo observatories in the last month. Prof. Salvatore Vitale explained that the possible detection of a black hole colliding with a neutron star could provide scientists with a better way to measure how quickly the universe is expanding.
