Using data on subatomic particles called neutrinos from Antarctica’s IceCube Neutrino Observatory, a team including MIT researchers has determined that Einstein’s theory of special relativity is correct. “Neutrinos had not yet been discovered when Einstein died, but his theory still predicts their behavior,” explains Kimberly Hickok for LiveScience.
A team including MIT research scientist Ulrich Faul has discovered that the Earth’s interior contains 1,000 times more diamonds than was previously thought, writes Sarah Emerson for Motherboard. The researchers believe that one to two percent of “craton roots,” which are the deepest sections of the “rock layers extending upwards of 200 miles through the Earth’s crust and mantle,” may contain diamonds.
MIT researchers have discovered a cache of diamonds below the surface of the Earth, deeper than any drilling expedition has ventured, reports the Agence France-Presse wire. This discovery was made after “scientists were puzzled by observations that sound waves would speed up significantly when passing through the roots of ancient cratons.”
Using “recorded sound waves from seismic activity like earthquakes and tsunamis,” MIT researchers have found that there may be a quadrillion tons of diamonds under the Earth’s surface, reports Sarah Gray for Fortune. The seismic data provided this information, “because the speed of sound waves changes depending on the temperature, density and composition of the earth they travel through,” explains Gray.
MIT research scientist Ulrich Faul used seismic data to determine that there may be diamonds underneath the Earth’s surface. “Located over 100 miles below Earth's tectonic plates are ancient, hard rocks called ‘cratonic roots’ that potentially consist of one to two percent diamond — totaling a quadrillion tons,” writes Lilly Price for USA Today.
A new study co-authored by Assistant Prof. Salvatore Vitale shows that the collision of a black hole and neutron star could provide insight into how quickly the universe is expanding. One such merger could allow physicists to calculate the expansion rate “as effectively as combining data from 50 different neutron-star collisions,” reports Meghan Bartels for Space.com.
A study led by MIT research scientist Ulrich Faul finds that diamonds are about 1,000 times more common in the Earth than previously thought, report Ayana Archie and Ralph Ellis for CNN. “The deposits sit some 90 to 150 miles below the Earth's surface, much deeper than current mining machinery allows,” write Archie and Ellis.
A team led by MIT research scientist Ulrich Faul ‘discovered a gigantic cache of diamonds deep beneath the Earth’s surface,’ writes Avery Thompson for Popular Mechanics. While the diamonds are too deep to be mined, “knowing that they’re there helps us learn more about our own planet and what it’s made of,” Thompson notes.
By using sound waves, MIT researchers have discovered that part of Earth’s stable crust may contain diamonds, reports Abbey Interrante for Newsweek. “This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it’s relatively common,” says research scientist Ulrich Faul.
MIT researchers have developed a new technique to 3-D print magnetic robots that could one day be used as biomedical devices, reports Erik Olsen for Quartz. “The engineers have enabled the bots to roll, crawl, jump, and even snap together like a Venus flytrap to grasp a pill and then roll away with it,” explains Olsen.
MIT researchers have created a new fabrication technique to create intricate, 3-D printed magnetic options that react to magnetic fields hitting them at different angles, reports Mark Wilson for Co.Design. In the future the structures, “could be placed in the human body, manipulated via wireless, harmless magnetism, and carry out intricate tasks like on-site drug delivery.”
Prof. Xuanhe Zhao and his colleagues have designed a 3D printer that can create shape-shifting soft materials. The group purposefully created the “materials and the method to be user friendly to enable a wide range of applications,” reports Fiona McMillan for Forbes.
Prof. Xuanhe Zhao speaks with WBUR about how he and his colleagues have developed a new technique to create soft, pliable structures that could carry out medical procedures within the human body. “Since the human body is soft, it's beneficial to develop a device that has a similar rigidity as soft tissues in the human body,” explains Zhao.
In this video, Mashable highlights a new method developed by MIT researchers to 3-D print soft robots that can crawl, fold and carry a pill. The team hopes the structures, which can be controlled with a magnet, could eventually be used as a medical device to take tissue samples or deliver treatments.
Lara Lewington reports for BBC Click on how MIT researchers have developed a technique to create 3-D printed soft structures that can be controlled with a magnet. Lewington explains that the structures could eventually be used in biomedical devices to “take images, extract samples, deliver drugs or even surround a blood vessel to control the pumping of blood.”
