Bendy Ice Uncurls
Without Breaking
When grown in tiny strands, ice
can bend and then snap back
into its original shape. Engineers
in China have used this quality
to fabricate what they say is the
most elastic water ice ever.

Sweat-Fueled
Fingertip Wearable
A new wearable device turns the
touch of a finger into a source
of power for small electronics.
A padding of carbon foam
electrodes absorbs sweat and
converts it into electrical energy.

Cov
The Cooperative Service Valve enables in-orbit servicing with less risk,
lower cost, and a much higher chance of success.
Color-coding and labels are also used to prevent operator error.
The CSV has four configurations for different working fluids, all
with essentially unchanged geometry and mechanics.
Spacecraft outfitted with the CSV enable in-orbit servicing with
less risk, lower cost, and a much higher chance of success. The
tools used to interface with the CSV, both on the ground and in
space, were also designed and tested by NASA. The CSV architecture
and ap proach is extensible to all space assets that could
potentially be fueled/refueled on and off the ground including
manned crew vehicles, planetary rovers, and space habitats.

Fuel Cell Boosts ElectricPowered
Vehicles
This fuel cell could power a variety of
transportation modes such as unmanned
underwater vehicles, drones, and eventually
electric aircraft.
McKelvey School of Engineering at Washington
University in St. Louis, Missouri
hile more people are using electric cars, designing electric-powered
planes, ships, and submarines is much harder
due to power and energy re quirements. A high-power fuel
cell was developed that uses a pH-gradient-enabled microscale
bipolar interface (PMBI). The direct borohydride fuel cell
operates at double the voltage of today's commercial fuel cells.
The pH-gradient-enabled microscale bipolar interface runs the
fuel cell with liquid reactants and products in submersibles, in
which neutral buoyancy is critical, while also being used in higherW
