Virtual Twitter to help researchers mimic the real thing


Twitter is great for making friends and sharing links, but researchers are also increasingly using it to study human interactions. This is more difficult than it sounds, since privacy settings and caps on server access can make it hard to gather research data from social networking sites.

It'd be much easier to have a virtual Twitter for researchers to experiment on, like a kind of 140-character lab rat. So Vijay Erramilli and colleagues at Telefonica Research, Spain have built one.

Visualizing Friendships


Visualizing data is like photography. Instead of starting with a blank canvas, you manipulate the lens used to present the data from a certain angle.

Bridge on Mars


t’s not the work of fastidious Face on Mars engineers – but there’s a natural bridge on the red planet.A new batch of NASA Mars Reconnaissance Orbiter (MRO) imagery includes this inspection of the Tartarus Colles region.

Chemists re-define hydrogen bond


The hydrogen bond is a wondrous thing. It helps give snowflakes their hexagonal symmetry; binds DNA into a double helix; shapes the three-dimensional forms of proteins; and even raises water's boiling point high enough to make a decent cup of tea.

New Discovery at the Large Hadron Collider?


Scientists at the Large Hadron Collison reported today they apparently have discovered a previously unobserved phenomenon in proton-proton collisions.

China's "Dragon" Sub Dives 3,759 Meters below Sea


China said Thursday its domestically-made manned submersible had successfully reached 3,759 meters below sea level with three crew on board, the China News Service reported.

Peer review highly sensitive to poor refereeing, claim researchers


Just a small number of bad referees can significantly undermine the ability of the peer-review system to select the best scientific papers. That is according to a pair of complex systems researchers in Austria who have modelled an academic publishing system and showed that human foibles can have a dramatic effect on the quality of published science.

Real invisibility threads would be fit for an emperor


FORGET the imaginary filaments used to weave the clothes that fooled the fabled emperor, can we make real invisible threads instead? Combining techniques used to produce light-bending metamaterials with those used to make optical fibres might just do the trick.

Old Star's Super-Hot Water Vapor Surprises Scientists


Scalding hot water vapor has been discovered in the atmosphere of an aging star, surprising scientists who thought the chemistry of such stars would forbid it.
