Things are always on the move in Alex Hubbard's work. A few years ago his videos recalled Jackson Pollock: shot from above, Hubbard poured paint on to Plexiglas to make wipe-clean colour fields, as household objects were arranged, smashed and given spraypaint coatings. For his new paintings (such as Eat Your Friends, 2012, pictured) he uses finds from his studio and the street on canvas and stills daubed with glow-in-the-dark resin.

For far too long, Burra has been dismissed as an eccentric minor talent. But this timely exhibition of his works – inspired by sailors and prostitutes in French ports and the jazz-era cool of 1930s Harlem streets, and including The Straw Man, pictured – should lead to a reassessment.

Channer's clothing-inspired sculptures (such as Slip, 2011, pictured) aren't afraid to get up close and personal with consumer culture. In this show, she collides current pieces with classics, so stretchy Topshop items, the flowing drapery of classical statues and Yves Saint Laurent's Le Smoking suit have all inspired giant digital prints that fall cape-like from the ceiling.

Here, Lisa Milroy has selected paintings from 1984 to 2011 that demonstrate her highly imaginative use of black. Emerging in the 1980s when painting was going through one of its periodic revivals, Milroy has continued to produce work of rare painterly charisma, taking as her subjects everything from door handles to geishas (Mourning Geisha, 2002, pictured).

Global boundaries, divisions and a culture of control are brought lyrically to light in Shilpa Gupta's work. Cages, steel security grills and iron gates rank among the forms her installations have taken in the past few years, though the prisons her works refer to are of the psychological kind (such as the Don't Hear Don't Speak Series, 2006, pictured).

On Kawara makes art that marks time. Central to this show is One Million Years, a live performance for which two participants will sit in a booth and recite dates from two books titled Past and Future (pictured). At BALTIC until 29 April 2012 Photograph: PR
This double bill at Gagosian's London galleries sees Ruff tackle two very different objects of fantasy. For nudes, he takes images of internet porn (such as dr02, 2011, pictured) and enlarges them to the point that the raw exposure of the performers' bodies becomes a suggestive haze of pixels. ma.r.s. meanwhile sees him adapt black-and-white Nasa images of the red planet to create giant painterly prints.

The word topophobia refers to an irrational dread of certain places or situations, and the multimedia artworks here evoke that exact anxiety. Marja Helander, a member of the nomadic Sámi peoples of Scandinavia, photographs herself dressed in traditional garb as she selects her groceries from a supermarket shelf (Go-between (noaidi) Inari, 2002, pictured). It's art that is almost not there – but what is there takes us somewhere else indeed. At The Bluecoat until 22 April 2012 Photograph: Marja Helander
