Audio Article: How to push, wiggle, or drill an object through granular material

Predicting what it takes to push through sand, gravel, or other soft media can help engineers drive a rover over Martian soil, anchor a ship in rough seas, and walk a robot through sand and mud. But modeling the forces involved in such processes is a huge computational challenge that often takes days to weeks to solve. Now, engineers at MIT and Georgia Tech have found a faster and simpler way to model intrusion through any soft, flowable material. Their new method quickly maps the forces it woul...

What does a sunrise and sunset sound like?

Using a new sonification toolkit, designed but MIT's Digital Humanities Lab, senior Moises Trejo was able to turn a sunrise and a sunset into sound. What the toolkit does is convert the annual times of sunrises and sunsets in a particular location and turns them into a simple soundwork. Depending on the settings it either becomes a two-voice melody (in a strange tuning) or a gradual modification of an evolving sound, or somewhere in between. In this piece the lower tone of the chord is the sunri...

Audio Article: Scientists build new atlas of ocean’s oxygen-starved waters

A team of MIT scientists have generated a detailed, three-dimensional "atlas" of the largest oxygen-deficient zones (ODZ) in the tropical Pacific. And though these ODZs make up less than 1 percent of the ocean’s total volume, they are a significant source of nitrous oxide, a potent greenhouse gas.

Audio Article: Sensor based on quantum physics could detect SARS-CoV-2 virus

A novel approach to testing for the presence of the virus that causes Covid-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the work, based on quantum effects, is still theoretical, these detectors could potentially be adapted to detect virtually any virus, the researchers say.

Engineers at MIT have developed a new approach to removing lead or other heavy-metal contaminants from water, in a process that they say is far more energy-efficient than any other currently used system, though there are others under development that come close. Ultimately, it might be used to treat lead-contaminated water supplies at the home level, or to treat contaminated water from some chemical or industrial processes.

Audio Article: Crowds can wise up to fake news

In the face of grave concerns about misinformation, social media networks and news organizations often employ fact-checkers to sort the real from the false. But fact-checkers can only assess a small portion of the stories floating around online. A new study by MIT researchers suggests an alternate approach: Crowdsourced accuracy judgements from groups of normal readers can be virtually as effective as the work of professional fact-checkers.

Thousands of different bacterial species live within the human gut. Most are beneficial, while others can be harmful. A new study from an MIT-led team has revealed that these bacterial populations can remake themselves within the lifetime of their host, by passing genes back and forth. They also found for people in industrialized societies this happens at much higher rates. Read the article: https://news.mit.edu/2021/microbiome-industrialized-gene-transfer-0331

Audio Article: Study predicts the oceans will start emitting ozone-depleting CFCs

The world’s oceans are a vast repository for gases including ozone-depleting chlorofluorocarbons, or CFCs. They absorb these gases from the atmosphere and draw them down to the deep, where they can remain sequestered for centuries and more. Marine CFCs have long been used as tracers to study ocean currents, but their impact on atmospheric concentrations was assumed to be negligible. Now, MIT researchers have found the oceanic fluxes of at least one type of CFC, known as CFC-11, do in fact affect...
