Printing 3-D graphene structures for tissue engineering

Ever since single-layer graphene burst onto the science scene in 2004, the possibilities for the promising material have seemed nearly endless. With its high electrical conductivity, ability to store energy, and ultra-strong ...

Seashell strength inspires stress tests

Mollusks got it right. They have soft innards, but their complex exteriors are engineered to protect them in harsh conditions. Engineers at the Indian Institute of Science and Rice University are beginning to understand why.

I sprint for exercise: NASA's iRAT study

Run far or run fast? That is one of the questions NASA is trying to answer with one of its latest studies—and the answers may help keep us in shape on Earth, as well as in space. Even with regular exercise, astronauts who ...

Horizontal gene transfer in E. coli

Escherichia coli O104 is an emergent disease-causing bacterium various strains of which are becoming increasingly well known and troublesome. The pathogen causes bloody diarrhea as well as and potentially fatal kidney damage, ...

The size of domestic animals has increased over time

The paper on Zooarchaeology 'Livestock management in Spain from Roman to post-medieval times: a biometrical analysis of cattle, sheep/goat and pig' by the researcher of the Department of Geography, Prehistory and Archaeology ...

Atmospheric release of BPA may reach nearby waterways

Water contamination by hormone-disrupting pollutants is threatening water quality around the world. Existing research has determined that harmful concentrations of Bisphenol-A (BPA), a chemical used in consumer products such ...

Chameleon proteins make individual cells visible

Researchers discovered a new mechanism of how fluorescent proteins can change colour. It enables the microscopic visualization of individual cells in their three-dimensional environment in living organisms.
