Artificial intelligence opens new window on complex urban issues (04/10/2019)

Understanding the workings and behaviors of a city requires knowledge of the different processes that allow people and other biological organisms to live and thrive, as well as understanding of their interrelationships—many of which are complicated and have yet to be deeply explored.

System helps smart devices find their position (04/10/2019)

A new system developed by researchers at MIT and elsewhere helps networks of smart devices cooperate to find their positions in environments where GPS usually fails.

Researchers think small to make progress towards better fuel cells (26/09/2019)

As renewable sources such as wind and solar are quickly changing the energy landscape, scientists are looking for ways to better store energy for when it's needed. Fuel cells, which convert chemical energy into electrical power, are one possible solution for long-term energy storage, and could someday be used to power trucks and cars without burning fuel. But before fuel cells can be widely used, chemists and engineers need to find ways to make this technology more cost-effective and stable.

'Nanochains' could increase battery capacity, cut charging time (26/09/2019)

How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current to run a device and ultimately fails.

Plasmonic silver nanoparticles advance toward ultrafast single-molecule detection (26/09/2019)

Detection of ultralow concentrations of substances requires devices that can provide ultrafast information processing and offer high detection limits. Plasmonic metal nanoparticles, especially those made of gold and silver, offer significant promise to detect substances rapidly and down to the single-molecule level.

A new way to turn heat into useful energy (26/09/2019)

An international team of scientists has figured out how to capture heat and turn it into electricity.

Brain-inspired computing could tackle big problems in a small way (14/09/2019)

While computers have become smaller and more powerful and supercomputers and parallel computing have become the standard, we are about to hit a wall in energy and miniaturization. Now, Penn State researchers have designed a 2-D device that can provide more than yes-or-no answers and could be more brainlike than current computing architectures.

Method to customize microbes for better biofuel production (14/09/2019)

Scientists at the US Department of Energy's Oak Ridge National Laboratory have demonstrated a method to insert genes into a variety of microorganisms that previously would not accept foreign DNA, with the goal of creating custom microbes to break down plants for bioenergy.

Making and controlling crystals of light (12/09/2019)

Optical microresonators convert laser light into ultrashort pulses travelling around the resonator's circumference. These pulses, called "dissipative Kerr solitons," can propagate in the microresonator maintaining their shape.

Physicists discover new material for highly efficient data processing (12/09/2019)

A new material could aid in the development of extremely energy efficient IT applications. The material was discovered by an international research team in cooperation with Martin Luther University Halle-Wittenberg (MLU). The electrons at the oxide interface of the material possess special properties that drastically increase the conversion rate of spin current to charge current. This is the foundation for future spintronic applications. The new material has been found to be more efficient than any previously investigated material, the team writes in the journal Nature Materials.
