Researchers discover the key to staying dry underwater

Oftentimes, the state of being “underwater” and being “wet” are used synonymously, but one can be wet without being underwater; and according to researchers at Northwestern University, one can be underwater without being wet (1). Through a combination of analysis of “air-retaining insect surfaces” used by aquatic insects, aging and...

On July 14, 2015, the LHCb (Large Hadron Collider beauty) experiment at CERN’s Large Hadron Collider announced the discovery of a new form of matter: the pentaquark particle. The theory describing these particles has existed since 1964, when the physicist Murray Gell-Mann proposed that protons and neutrons are made of...

 
 

A discovery in fluid dynamics with cosmological implications

The inflationary universe: A new discovery in relativistic fluid dynamics could help scientists understand the expansion and fate of the universe.

Normally, fluid dynamics and cosmology are widely separate disciplines. Problems like the flow of water through a pipe have little to do with the evolution and fate of the universe; but, as it turns out, if one allow fluids to move near the speed of light, one will find some interesting properties...

A group of astronomers from the US, Europe, South Africa, and Chile have determined that, approximately 70,000 years ago, a recently discovered star is likely to have passed through the Oort Cloud, a region at the edge of the solar system from which comets arise (1). Its average distance at...

 
 

Blacklist for fossil fuels revealed to limit global warming

A recent analysis reveals which nations should especially refrain from exploiting much of their carbon-based energy reserves when limiting global warming temperature to 2 °C, Michael Jakob and Jerome Hilaire reported online in the journal Nature on January 7, 2015.
