First light for GRAVITY: Phase referencing optical interferometry for the Very Large Telescope Interferometer [PDF]
, 2017 GRAVITY is a new instrument to coherently combine the light of the European Southern Observatory Very Large Telescope Interferometer to form a telescope with an equivalent 130 m diameter angular resolution and a collecting area of 200 m2.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains
FEBS Open Bio, EarlyView.The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Laboratory Investigation The Effect of Porosity of Permeable Obstacle on Control of Gravity Current [PDF]
علوم و مهندسی آبیاری, 2017 Gravity current is a phenomenon caused by density difference between two fluids and due to this phenomenon the fine sediments can be moved to the body dam and as a result causes for many serious problems for dam intake.

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system
FEBS Open Bio, EarlyView.An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...
