New biomaterial gets 'sticky' with stem cells

(Phys.org)—Just like the bones that hold up your body, your cells have their own scaffolding that holds them up. This scaffolding, known as the extracellular matrix, or ECM, not only props up cells but also provides attachment ...

DNA cages 'can survive inside living cells'

(PhysOrg.com) -- Scientists at Oxford University have shown for the first time that molecular cages made from DNA can enter and survive inside living cells.

Lighting up plant cells to engineer biology

Cambridge researchers have developed a new technique for measuring and mapping gene and cell activity through fluorescence in living plant tissue.

Berkeley Lab Scientists Create 'Molecular Paper' (w/ Video)

(PhysOrg.com) -- Berkeley Lab scientists have created "molecular paper," the largest two-dimensional polymer crystal self-assembled in water to date. This entirely new sheet material is made of peptoids, engineered polymers ...

New hybrid microscope offers unparalleled capabilities

A microscope being developed at the Department of Energy's Oak Ridge National Laboratory will allow scientists studying biological and synthetic materials to simultaneously observe chemical and physical properties on and ...

Designer piercings: New membrane pores with DNA nanotechnology

A new way to build membrane-crossing pores, using Lego-like DNA building blocks, has been developed by scientists at UCL, in collaboration with colleagues at the University of Cambridge and the University of Southampton.

Chemists engineer plants to produce new compounds

(PhysOrg.com) -- In work that could expand the frontiers of genetic engineering, MIT chemists have, for the first time, genetically altered a plant to produce entirely new compounds, some of which could be used as drugs against ...
