The laser beam as a "3D painter"

(Phys.org)—There are many ways to create three dimensional objects on a micrometer scale. But how can the chemical properties of a material be tuned at micrometer  precision? Scientists at the Vienna University of Technology ...

Organic carbon from Mars, but not biological

(Phys.org) -- Molecules containing large chains of carbon and hydrogen--the building blocks of all life on Earth--have been the targets of missions to Mars from Viking to the present day. While these molecules have previously ...

Electric charge disorder: A key to biological order?

Theoretical physicist Ali Naji from the IPM in Tehran and the University of Cambridge, UK, and his colleagues have shown how small random patches of disordered, frozen electric charges can make a difference when they are ...

Visualization of DNA synthesis in vivo

Researchers of the University of Zurich have discovered a new substance for labeling and visualization of DNA synthesis in whole animals. Applications for this technique include identifying the sites of virus infections and ...

Catching molecular motion at just the right time

University of Oregon researchers have devised a mathematically rich analytic approach to account for often-missing thermodynamic and molecular parameters in molecular dynamic simulations.

Scientists construct synthetic proteins that sustain life

(PhysOrg.com) -- In a groundbreaking achievement that could help scientists "build" new biological systems, Princeton University scientists have constructed for the first time artificial proteins that enable the growth of ...
