New imaging technique peers inside living cells

To undergo high-resolution imaging, cells often must be sliced and diced, dehydrated, painted with toxic stains, or embedded in resin. For cells, the result is certain death.

Mechanical cues reprogram normal cell lines into stem-like cells

Scientists at the University at Buffalo and other institutions have turned cells normally used as model cells, known as immortalized cells, into stem or, as they call it, "stem-like" cells, using nothing more than mechanical ...

Why don't beetles freeze in the winter?

For 37 years, Queen's University Biochemistry professor Peter Davies has been unraveling the mystery of why some organisms including insects and fish don't freeze in the winter. His research into insect antifreeze protein ...

Lessons from herbicide tolerance

(Phys.org)—Polyamines are widespread and important organic compounds involved in multiple cellular processes in living organisms. Their levels are highly regulated through a combination of processes including synthesis, ...

'Just clicking' a molecule to a biomolecule for another function

Researchers have reported a material that controls the behavior of cells in a dynamic way, just as happens in biology. A new technique uses functional components that can be 'clicked' to a material using vitamin H. Researchers ...

New non-invasive imaging method for showing oxygen in tissue

Learning how to look inside a body without having to cut it open is still an important part of medical research. One of the great challenges in imaging remains the visualization of oxygen in tissue. A team led by Prof. Vasilis ...
