Photorealism in the digital age
Here is the fourth and final volume in Abrams' definitive series on Photorealism, one of the most popular contemporary art movements. The first three volumes reproduced all Photorealist paintings created before 2000. 'Photorealism In The Digital Age' includes 841 full-colour artworks produced since 2000. Photorealists work painstakingly from photographs to create startlingly real paintings, sometimes as few as four in any given year. Where once they used cameras and film as tools for gathering information, they now rely on digital technology, which has vastly expanded the amount of detail that can be captured in an image. They bring new insights to vernacular subjects and succeed in making the commonplace \"uncommon\". Meisel covers every major Photorealist still active as well as artists new to the movement. For the first time he also includes Photorealist-like sculpture.

Life is strange
Life is Strange displays and dissects the bewildering flood of images with which the twentieth century burst into the living rooms of bemused Dutch families. Thanks to the rapid development of photography, suddenly everyone was given a chance to take part in unknown events taking place in every corner of the world. 'Photographic all-sorts from everywhere,' as the Dutch illustrated magazine Het Leven called them: photographs of dramatic accidents, extraordinary events, far-off peoples, remarkable inventions, unusual customs, and larger-than-life characters. From the 12 million of these images held in the Spaarnestad collection of the National Archives of the Netherlands, the photographer and curator Rob Moorees hand-picked a stunning selection of startling visual impact. Dutch writer Maarten Asscher wrote an essay giving these photographic faits divers their place in history. Photography researcher Saskia Asser put the magazine Het Leven into the context of the rise of the illustrated press in the Netherlands. This is a poignant historic record as well as a fascinating image of the human condition.00Exhibition: Huis Marseille, Amsterdam, The Netherlands (12.06.-06.09.2015).

Serial crystallography captures dynamic control of sequential electron and proton transfer events in a flavoenzyme
Flavin coenzymes are universally found in biological redox reactions. DNA photolyases, with their flavin chromophore (FAD), utilize blue light for DNA repair and photoreduction. The latter process involves two single-electron transfers to FAD with an intermittent protonation step to prime the enzyme active for DNA repair. Here we use time-resolved serial femtosecond X-ray crystallography to describe how light-driven electron transfers trigger subsequent nanosecond-to-microsecond entanglement between FAD and its Asn/Arg-Asp redox sensor triad. We found that this key feature within the photolyase-cryptochrome family regulates FAD re-hybridization and protonation. After first electron transfer, the FAD

isoalloxazine ring twists strongly when the arginine closes in to stabilize the negative charge. Subsequent breakage of the arginine–aspartate salt bridge allows proton transfer from arginine to FAD

. Our molecular videos demonstrate how the protein environment of redox cofactors organizes multiple electron/proton transfer events in an ordered fashion, which could be applicable to other redox systems such as photosynthesis.
A reduction reaction is usually equated with an electron transfer reaction. Now, ultrafast time-resolved serial femtosecond X-ray crystallography has enabled the visualization of the stepwise structural changes that occur after electron transfers have been observed in the light-triggered reduction of flavin adenine dinucleotide catalysed by DNA photolyase.
