Protocell arrays for simultaneous detection of diverse analytes
Bacterial strains E. coli strain DH10β was used for all cloning and plasmid preparations. E. coli strain BL21 Star (DE3) ΔlacIZYA was created by lambda red recombination60 and used for…
Stem-cell start-ups seek to crack the mass-production problem
In the laboratory, induced pluripotent stem (iPS) cells can seem like magic: derived from differentiated cells, they can then morph into surprisingly good replacements for pancreatic, brain, eye, heart and…

The chimaera challenge
It’s 2036, and you have kidney failure. Until recently, this condition meant months or years of gruelling dialysis, while you hoped that a suitable donor would emerge to provide you…

Great apes’ consonant and vowel-like sounds travel over distance without losing meaning — ScienceDaily
Scientists have shown that orangutan call signals believed to be closest to the precursors to human language, travel through forest over long distances without losing their meaning. This throws into…
How high-fat diets allow cancer cells to go unnoticed — ScienceDaily
A high-fat diet increases the incidence of colorectal cancer. Cold Spring Harbor Laboratory Fellow Semir Beyaz and collaborators from Harvard Medical School and Massachusetts Institute of Technology have discovered that…
