New nanogel for drug delivery

A new type of self-healing hydrogel has been developed by MIT chemical engineers that can carry one or two drugs at a time. The gel consists of a mesh network made of nanoparticles and polymers that can be injected through a syringe and released over several days, targeting specific tissues and allowing for long-term drug delivery.

Smarter multicore chips

Researchers at MIT developed a system that cleverly distributes data around multicore chips' memory banks, improving execution times by 18 percent on average while increasing energy efficiency. In simulations involving a 64-core chip, the system increased computational speeds by 46 percent while reducing power consumption by 36 percent.

Better how-to videos

Researchers at MIT and Harvard University developed a new system called Crowdy that recruits viewers to create subgoal labels for educational videos. The system improves video annotations by leveraging crowdsourcing, reducing costs to $1 per minute, and enhancing learner retention and satisfaction.

Splash down

A team from MIT and the University of Liege presents high-speed images showing that raindrops can act as a dispersing agent, catapulting contaminated droplets far from their leaf source. The researchers found that a plant's mechanical properties, particularly its compliance, determine the range of dispersal.

Wrinkle predictions

A team of MIT mathematicians developed a theory predicting wrinkled patterns on curved surfaces, confirmed through experiments. The theory states that curvature is the main parameter determining pattern formation, with thicker shells forming hexagonal patterns and thinner shells resulting in labyrinthine configurations.

Privacy challenges

MIT researchers report that just four pieces of information are enough to identify 90% of people in a data set. Adding coarse-grained price information reduces the number of data points needed to reach 94%. The study highlights the risks of re-identification and encourages socially beneficial uses of big data.

Software that knows the risks

Researchers at MIT have developed software that assesses risk in planning algorithms, suggesting low-risk alternatives when a solution is not possible. The system uses probabilistic models to determine the feasibility of a plan and can offer modifications to relax constraints or add resources to mitigate risks.

A twist on planetary origins

Researchers at MIT and Purdue University have found that meteorites are not building blocks of planets, but rather byproducts of a violent planetary process. Computer simulations show that large moon-sized bodies likely existed before chondrules formed, which were then created by collisions of these bodies.

Vision system for household robots

Researchers at MIT develop an algorithm that allows household robots to recognize four times as many objects as traditional methods, reducing misidentifications. The new approach uses a representative sampling technique, sampling hypotheses across successive images, and evaluating them more efficiently.

Study: Industrial clusters fuel economies

A new MIT study reveals that industrial clusters across various industries drive economic growth by fostering job creation, innovation, and the formation of new industries. The research suggests that regions can improve their economic performance by investing in and extending their comparative advantage rather than chasing global hotsp...

New way to turn genes on

Researchers at MIT have successfully turned on any desired gene in living cells using the CRISPR/Cas9 system. This breakthrough enables scientists to study gene function and identify genes involved in diseases, such as melanoma. The new method has also been used to screen for genes that confer resistance to cancer drugs.

Losing air

Researchers found that tens of thousands of small impacts could efficiently jettison Earth's entire primordial atmosphere, while giant impacts would be less effective. The team's calculations suggest that the early Earth was likely devoid of its original atmosphere, with Venus and Mars also experiencing significant atmospheric loss.

Two sensors in one

New nanoparticles can perform magnetic resonance imaging (MRI) and fluorescent imaging simultaneously, allowing for the tracking of specific molecules produced in the body. The particles were demonstrated to detect vitamin C in mice, showing strong fluorescent signals where vitamin C is present but little MRI contrast.

Recommendation theory

The MIT researchers' model assumes that large groups of ratings can be clustered together and described probabilistically. They found that just five clusters were enough to account for most of the variation in a population, suggesting that collaborative filtering yields nearly optimal predictions.

Pulling together the early solar system

A team of researchers has provided evidence that the early solar system's protoplanetary disk was shaped by an intense magnetic field, driving gas toward the sun at a rapid rate. The study analyzed a meteorite sample, extracting individual grains and measuring their magnetic orientations to determine the original magnetic field.

Atomic timekeeping, on the go

Researchers at MIT and Draper Laboratory have developed a new atomic timekeeping approach that could enable more stable and accurate portable atomic clocks. The system suppresses the AC Stark shift effect, allowing for smaller, less expensive devices with improved accuracy compared to current fountain clocks.
