A preserved heart muscle (1) is removed and replaced with a soft synthetic matrix (2). The two structures (inner cardiac tissue and synthetic matrix) (3) are bonded using a newly developed adhesive, TissueSil (4). The resulting piece is the biohybrid heart containing the preserved intracardiac structures and synthetic heart muscle (5).

Engineers design bionic “heart” for testing prosthetic valves, other cardiac devices

Device made of heart tissue and a robotic pumping system beats like the real thing.

MIT Associate Professor Noelle Eckley Selin (left) and former graduate student Emil Dimanchev SM ’18 used a new method to analyze the impacts of current and proposed state-level renewable energy and carbon pricing policies. Their study yielded some unexpected outcomes on the health benefits of the policies they examined.

Study: State-level adoption of renewable energy standards saves money and lives

MIT researchers review renewable energy and carbon pricing policies as states consider repealing or relaxing renewable portfolio standards.

Experiments identified one gene, which the researchers named Bradyzoite-Formation Deficient 1 (BFD1), as the only gene both sufficient and necessary to prevent the transition from tachyzoite to bradyzoite stages of T. gondii infection. The findings may inform research into potential therapies for toxoplasmosis, or even a vaccine.

Putting a finger on the switch of a chronic parasite infection

Researchers find master regulator needed for Toxoplasma gondii parasite to chronically infect host; promising step toward infection treatment, prevention.

The same neurons that store feelings of reward also store memories that suppress fearful ones, a new study shows. In this image, the broader population of Ppp1r1b neurons is labeled green while neurons storing a specific fear extinction memory are labeled red.

With these neurons, extinguishing fear is its own reward

The same neurons responsible for encoding reward also form new memories to suppress fearful ones.

A physics-based analysis of U.S. elections finds that the electorate has become more polarized over time, leading to an unstable situation in which very small chages in opinion can lead to wide swings in electoral outcomes.

Study uses physics to explain democratic elections

U.S. elections have become more “unstable,” sometimes swinging in the opposite direction from the greater electorate’s preferences.

K. Renee Horton, NASA scientist and past president of the National Society of Black Physicists, speaks with students at a recent physics conference. Due to a climate that has consistently excluded African-Americans from succeeding in physics and astronomy, a new task force report urges significant cultural changes in these fields.

Making physics and astronomy more welcoming to African-American students

Report co-chaired by MIT professor cites need for “sweeping changes” in academic culture.

A new study reveals that although a significant percentage of Americans believed Hillary Clinton would win the 2016 presidential election, people rarely used the pronoun “she” when referring to the next president.

“She” goes missing from presidential language

Even when people believed Hillary Clinton would win the 2016 election, they did not use “she” to refer to the next president.
