Improving lithium-ion batteries with nanoscale research

New research led by an electrical engineer at the University of California, San Diego is aimed at improving lithium (Li) ion batteries through possible new electrode architectures with precise nano-scale designs. The researchers ...

Climate scientists see better climate models, warmer future

(Phys.org) —Over the next century, most of the continents are on track to become considerably warmer, with more hot extremes and fewer cold extremes. Precipitation will increase in some parts of the world but will decrease ...

Tracking devices explore concussions on the playing field

Kody Campbell admits to having his bell rung a few times. As a Mustangs football player for five years (2007-11), Campbell never sustained a concussion himself, but knows of many others who did. He is well aware the hard ...

Building on mud: When can we start?

A Queensland engineer can now predict how long it takes for reclaimed land to become suitable for development, potentially saving millions of dollars in building costs.

Building disaster-relief phone apps on the fly

Researchers at MIT's Computer Science and Artificial Intelligence Laboratory and the Qatar Computing Research Institute have developed new tools that allow people with minimal programming skill to rapidly build cellphone ...

Following the missteps of giants

In the early 1950s, famed chemist Linus Pauling announced that he had won the race to figure out the structure of DNA. It is a triple-helix, Pauling said, arranged with the DNA bases sticking out of the molecule.

The intergalactic medium in the young universe

(Phys.org) —In its earliest years, the universe was so hot that electrons and protons could not bind together in neutral atoms: all of the gas in the cosmos was ionized. Then, after 380,000 years of expansion, the universe ...

Pigeon wingman rules

Travelling in flocks may make individual birds feel secure but it raises the question of who decides which route the group should take.

New method speeds up stabilisation of chaotic systems

(Phys.org) —When chaos threatens, speed is essential; for example, when a pacemaker needs to stabilise an irregular heartbeat or a robot has to react to the information received from its environment. Both cases require ...
