Color-Changing Molecular Stress Sensor

in technology

It is helpful - even life-saving - to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that’s easy to read is a challenge. A new report shows that a simple color change can signal such a warning.

Hydrogen-powered symbiotic bacteria in deep-sea hydrothermal vent mussels

in technology, biology

During a recent expedition to hydrothermal vents in the deep sea, researchers from the Max Planck Institute of Marine Microbiology and the Cluster of Excellence MARUM discovered mussels that have their own on-board ‘fuel cells’, in the form of symbiotic bacteria that use hydrogen as an energy source.

Nanoelectronics To Get A Nanobattery - Lithium Ion Battery In A Nanowire

in technology

A new study shows that an entire lithium ion energy storage device can be packed into a single nanowire. The researchers believe their creation is as small as such devices can possibly get, and could be valuable as a rechargeable power source for new generations of nanoelectronics. Lithium ion batteries are used in consumer electronics, electric vehicles and aerospace applications.

World’s first ‘printed’ aircraft, which could revolutionise the economics of aircraft design

in technology

Engineers at the University of Southampton have designed and flown the world’s first ‘printed’ aircraft, which could revolutionise the economics of aircraft design.

A Flexible, Transparent Lithium-ion Battery - A leap from science fiction to reality?

in technology

Are you searching for that battery? Sorry, that is transparent! Stanford scientists report the invention of a transparent battery.  Since key active materials in batteries cannot yet be made transparent or replaced with transparent alternatives, they made the battery such that its nontransparent components were too small to be seen by the naked eye.

Glucose meters to be used for food, water and blood chemistry- new study

in technology, environment, medicine, biology, omics

Glucose meters can do more than just measuring blood glucose.  A new invention published in Nature Chemistry claims that glucose meters can be used for the quantitative detection of a broad range of target molecules in blood, water or food.

Diamonds are the hardest, but evaporate under exposure to light

in technology

A new study shows that even the earth's hardest naturally occurring material, the diamond, is not forever.  The scientists have now discovered that diamonds evaporate under exposure to light.

Geoneutrinos keep us warm? Measuring radioactive sources of Earth's heat

in technology, environment

What keeps the Earth cooking? Though the Earth has cooled since its formation,  the core of the Earth may be still as hot as 7000 K. The main source of Earth's internal heat is produced through decay of radiogenic isotopes, in particular radioisotopes of uranium, thorium and potassium. This process provides a continuing heat source in the Earth's interior.
