At right, scanning electron microscope (SEM) images show the two types of lithium deposits, the bulky, mossy type (at top), which grows from its base, and the needle-like dendritic type (bottom), which grows from the tips. At left, SEM images show the effect of a blocking layer of ceramic material that limits the growth of the mossy deposits.

In batteries, a metal reveals its dual personality

Branchlike deposits grow on lithium electrode surfaces in two ways, one much more damaging.

Clownfish fight off predators of anemones that in turn provide habitats for the clownfish, an example of mutualism. But mutualistic relationships aren’t always set in stone; depending on environmental conditions, once-simpatico species can become competitors.

A mutual breakdown

Species relationships devolve from jointly beneficial to competitive in benign environments.

Lab experiments carried out by an MIT and Oxford University team provide detailed information about how a liquid moves through spaces in a porous material, revealing the key role of a characteristic called wettability.

Study reveals new physics of how fluids flow in porous media

Key flow mechanisms, crucial to carbon sequestration and fuel-cell operation, have been visualized.

Researchers have developed a new way of imaging the middle ear using infrared light, which they say could provide much more accurate diagnosis of ear infections.

A new eye on the middle ear

Shortwave infrared instrument from MIT could see deeper, help improve diagnosis of ear infections.

Michael Floyd, a research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences, says that in developing seismic hazard assessments, it’s important to consider afterslip and slowly creeping faults, which occur often and over long periods of time following the more obvious earthquake.

2014 Napa earthquake continued to creep, weeks after main shock

Continuing seismic activity could pose additional hazards to infrastructure.

New MIT heads of house for fall 2016: (clockwise from top left) Nuria Jane and Alberto Rodriguez; Pablo Jarillo-Herrero (who will co-lead with Empar Rollano-Hijarrubia, not pictured); Laurie Lynn and Jared Berezin (with Shakedown); and Kristen Covino.

New heads of house join undergraduate and graduate communities to start the fall semester

Areas of expertise include robotics, writing, physics, jewelry-making, and breakfast cereal.

Mars’ Valles Marineris canyon, pictured, spans as much as 600 kilometers across and delves as much as 8 kilometers deep. The image was created from over 100 images of Mars taken by Viking Orbiters in the 1970s.

New technique may help detect Martian life

A novel interpretation of Raman spectra will help the 2020 Mars rover select rocks to study for signs of life.

Researchers at MIT have for the first time identified the structure of class I fumarate hydratase enzyme, which could be a target for drugs combatting diseases prevalent in the developing world.

Targeting neglected diseases

New enzyme-mapping advance could help drug development.

Membrane structures in plant xylem from different species are being investigated for use in water filtration.

J-WAFS Solutions program awards $750,000 in commercialization grants

Four new projects and one renewal receive $150,000 in funding for 2016-2017.

Researchers designed and tested several types of optical sensors that could be placed at the tip of an epidural needle and determined that the best is one that relies on Raman spectroscopy. This technique, which uses light to measure energy shifts in molecular vibrations, offers detailed information about the chemical composition of tissue.

Needles that hit the right mark

New sensor could help anesthesiologists place needles for epidurals and other medical procedures.

Researchers at MIT have developed a new way of making windows that can switch from transparent to opaque using electrochromic materials. Once the glass is switched from clear to dark, or vice versa, the new system requires little to no power to maintain its new state; unlike other materials, it only needs electricity when it’s time to switch back again.

MIT develops self-shading windows

New system can rapidly switch glass from transparent to dark — and keep it that way without power.

Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory and Indiana University at Bloomington describe a new system that permits database queries for genome-wide association studies but reduces the chances of privacy compromises to almost zero.

Protecting privacy in genomic databases

System helps ensure databases used in medical research will not leak patients’ personal information.
