Melanin from Jurassic-era mollusk could lead to new tool for cancer diagnosis
New device allows for manipulation of differentiating stem cells
Electroporation is a powerful technique in molecular biology. By using an electrical pulse to create a temporary nanopore in a cell membrane, researchers can deliver chemicals, drugs, and DNA directly into a single cell.
'Quadruple helix' DNA discovered in human cells
In 1953, Cambridge researchers Watson and Crick published a paper describing the interweaving 'double helix' DNA structure - the chemical code for all life. Now, in the year of that scientific landmark's 60th Anniversary, ...
How stable are arsenic compounds found in edible algae?
Researchers at UPM have studied the stability of diverse arsenic species found in edible marine algae and have established the best conditions for their storage and preservation.
Into the breach: Transporting molecular cargo through algal cell walls
Two for the price of one: Single-molecule microscopy simultaneously monitors protein structure and function
Preserving the genetic diversity of livestock species
Muhammad Anzar, a research scientist for Agriculture and Agri-Food Canada, is an expert in cryopreservation—you know, freezing living matter to cheat death.
New tech application keeps bacteria from sticking to surfaces
Just as the invention of nonstick pans was a boon for chefs, a new type of nanoscale surface that bacteria can't stick to holds promise for applications in the food processing, medical and even shipping industries.
The road also taken: Alternative and hidden pathways in biological electron transfer
Scientists solve mystery of the eye
Where no lab has gone before: Single-Molecule Electrokinetic Traps
Scientists create first living organism that transmits added letters in DNA 'alphabet'
Scientists at The Scripps Research Institute (TSRI) have engineered a bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature. The cells of this unique bacterium ...
Scientists use 3D printing to make artificial blood vessels
The tangled highway of blood vessels that twists and turns inside our bodies, delivering essential nutrients and disposing of hazardous waste to keep our organs working properly has been a conundrum for scientists ...
New study revisits Miller-Urey experiment at the quantum level
For the first time, researchers have reproduced the results of the Miller-Urey experiment in a computer simulation, yielding new insight into the effect of electricity on the formation of life's building ...
