Scientists from the London Centre for Nanotechnology at UCL have shown that animal cells behave according to the theory of poroelasticity when mechanically stimulated in a way similar to that experienced in organs within the body. The results indicate that the rate of cell deformation in response to mechanical stress is limited by how quickly water can redistribute within the cell interior.

Researchers have created an atomic gas in the laboratory that nonetheless has negative Kelvin values. These negative absolute temperatures have several apparently absurd consequences: although the atoms in the gas attract each other and give rise to a negative pressure, the gas does not collapse - a behaviour that is also postulated for dark energy in cosmology.
