Researchers have designed a new programming language that lets application developers manage memory more efficiently in programs that deal with scattered data points in large data sets. In tests on several common algorithms, programs written in the new language were four times as fast as those written in existing languages.

Faster parallel computing

New programming language delivers fourfold speedups on problems common in the age of big data.

A new imaging system can read closed books. “The Metropolitan Museum in New York showed a lot of interest in this, because they want to, for example, look into some antique books that they don’t even want to touch,” says Barmak Heshmat, a research scientist at the MIT Media Lab.

Judging a book through its cover

New computational imaging method identifies letters printed on first nine pages of a stack of paper.

A new system that can anticipate room assignments and suggest which nurses to assign to patients for C-sections and other procedures provided satisfactory recommendations to nurses 90 percent of the time.

Robot helps nurses schedule tasks on labor floor

System from Computer Science and Artificial Intelligence Lab suggests where to move patients and who should do C-sections.

“It’s intuitive that if a bunch of people are randomly walking around an area, the number of times they bump into each other will be a surrogate of the population density,” says Cameron Musco, an MIT graduate student in electrical engineering and computer science. “What we’re doing is giving a rigorous analysis behind that intuition, and also saying that the estimate is a very good estim...

Clusters of four or more small satellites could look at a single location on Earth from multiple angles, and measure that location’s total reflectance with an error that is half that of single satellites in operation today, an MIT-led study suggests.

Better views with smaller satellites

Batches of shoebox-sized satellites could improve estimates of Earth’s reflected energy.

“Multicore systems are really hard to program,” says Daniel Sanchez, an assistant professor in MIT’s Department of Electrical Engineering and Computer Science. “You have to explicitly divide the work that you’re doing into tasks, and then you need to enforce some synchronization between tasks accessing shared data. What this architecture does, essentially, is to remove all sorts of expli...

Parallel programming made easy

New chip design makes parallel programs run many times faster and requires one-tenth the code.

This illustration shows the merger of two black holes and the gravitational waves that ripple outward as the black holes spiral toward each other. The black holes — which represent those detected by LIGO on Dec. 26, 2015 — were 14 and 8 times the mass of the sun, until they merged, forming a single black hole 21 times the mass of the sun. In reality, the area near the black holes would appear ...

For second time, LIGO detects gravitational waves

Signal was produced by two black holes colliding 1.4 billion light years away.
