In the 2,000 or so years since the Roman Empire employed a naturally
occurring form of cement to build a vast system of concrete aqueducts and other
large edifices, researchers have analyzed the molecular structure of natural
materials and...

Borrowing from Mother Nature, a team of MIT researchers has built a school of
swimming robo-fish that slip through the water just as gracefully as the real
thing, if not quite as fast.
Mechanical engineers Kamal Youcef-Toumi and Pablo...

Not far beneath the ocean's surface, tiny phytoplankton swimming upward in a
daily commute toward morning light sometimes encounter the watery equivalent of
Rod Serling's Twilight Zone: a sharp variation in marine currents that traps...

A gas used for fumigation has the potential to contribute significantly to
future greenhouse warming, but because its production has not yet reached high
levels there is still time to nip this potential contributor in the bud,
according to...

Modern manufacturing methods are spectacularly inefficient in their use of
energy and materials, according to a detailed MIT analysis of the energy use of
20 major manufacturing processes.
Overall, new manufacturing systems are...

For the first time, MIT researchers have shown they can genetically engineer
viruses to build both the positively and negatively charged ends of a
lithium-ion battery.
The new virus-produced batteries have the same energy capacity and...

The thin-film EL devices use perovskite oxides, typified by barium titanate
(BaTiO3), which has long been used as capacitor material for
electronic circuits. With an emission starting voltage of ≈10 V AC, the power
source...

The answer to the looming fuel crisis in the 21st century may be found by
thinking small, microscopic in fact. Microscopic organisms from bacteria and
cyanobacteria, to fungi and microalgae, are biological factories that are
proving to be...

The human heart has a notorious reputation for being unable to heal itself,
but new research suggests it is capable of at least some self-repair. Using
carbon dating to gauge the age of heart cells, scientists have found that low
