At last, a simple 3-D printer for metal

Used to produce three-dimensional objects of almost any type, across a range of industries, including healthcare, aviation and engineering, 3-D printed materials have come of age during the last decade. Research published ...

Fossil teeth show how reptiles adapted to change

Marine predators that lived in deep waters during the Jurassic Period thrived as sea levels rose, while species that dwelled in the shallows died out, research suggests.

Veiled supernovae provide clue to stellar evolution

At the end of its life, a red supergiant star explodes in a hydrogen-rich supernova. By comparing observation results to simulation models, an international research team found that in many cases this explosion takes place ...

Reducing nitrogen inputs prevents algal blooms in lakes

For decades, experts have debated whether reducing the amount of nitrogen flowing into lakes can improve water quality in the long-term, even though blue-green algae can bind nitrogen from the air. However, no lakes with ...

3-D models from cheap video cameras

Hannes Ovrén shows in his doctoral thesis in computer vision at Linköping University how 3-D models can be created from video films recorded with simple body- or robot-mounted cameras. The research opens new possibilities ...

Simulations reveal role of calcium in titanium implant acceptance

Titanium-based materials are widely used in medical implant technology. Coating the surface of titanium materials with biologically active molecules has recently shown promise to improve how cells adhere to implants and promote ...
