Liquid metal-organic frameworks remain porous

Metal-organic frameworks are used in a wide range of applications, from gas sorption and separation, catalysis and ion transport, thanks to their exceptional porosity. However, most MOFs are rigid crystalline materials and take the form of a powder, which makes them difficult to store or manipulate. A team of researchers in France, the UK and Read more about Liquid metal-organic frameworks remain porous[…]

Long polymer sequences show promise for data storage

Using a mass-spectrometry technique, researchers in France have succeeded in reading several bytes of data recorded in a long chain of synthetic polymers for the first time. The new result means that polymers might be used to store data on a scale that is around 100 times smaller than that of current hard drives. Digital Read more about Long polymer sequences show promise for data storage[…]

Glyoxalase, a natural and powerful damage prevention system in skin cells

Protein alterations produced in the very heart of cells themselves over time irreversibly damage cells, and ultimately tissue. Glyoxalase (GO) is one natural and powerful damage prevention system in the body, and according to new experiments by researchers at UPMC-Sorbonne Université and Dior Science, this system exists in skin cells. GLO consists of two intracellular Read more about Glyoxalase, a natural and powerful damage prevention system in skin cells[…]

Glyoxalase – skin’s inner defense system – limits protein damage in cells and tissues

The collaboration between UPMC and Dior Science began 18 years ago and was instigated by UPMC laboratory director Bertrand Friguet and research scientist Carine Nizard of LVMH laboratories. We talk to Carine Nizard and long-time colleague Isabelle Petropoulos of the UPMC about the group’s work. Bel Dumé: Could you explain the background to your work?

Glyoxalase enzymes prevent skin ageing

Skin ageing is one of the starkest reminders of the passage of time. It is a complex process resulting from both chronoageing, which is intrinsic, and photoageing, which is extrinsic and caused by exposure to ultraviolet rays from the Sun. As skin ages it loses its elasticity, the epidermis and dermis progressively thin and cell Read more about Glyoxalase enzymes prevent skin ageing[…]
