Nanotech researchers develop artificial pore

(PhysOrg.com) -- Using an RNA-powered nanomotor, University of Cincinnati (UC) biomedical engineering researchers have successfully developed an artificial pore able to transmit nanoscale material through a membrane.

Weightlessness weighs heavy on genes -- a fly's perspective

On Earth all biology is subjected to gravity. Some biological systems require gravity for correct orientation (geotropism: plants grow up, roots grow down). In the absence of gravity even human biology is affected: astronauts ...

Never mind the selfish gene – ribosomes are the missing link

Since the discovery that DNA encodes genetic information, research on the evolution of life has focused on its genetic origins. Following this "genes-first" approach, Oxford University evolutionary biologist Richard Dawkins ...

Dually noted: New CRISPR-Cas9 strategy edits genes two ways

The CRISPR-Cas9 system has been in the limelight mainly as a revolutionary genome engineering tool used to modify specific gene sequences within the vast sea of an organism's DNA. Cas9, a naturally occurring protein in the ...

How fruit flies taste water

(PhysOrg.com) -- The ability to detect water and regulate water intake is essential for all animals because if cells have too little or too much water the consequences for the animal can be disastrous. It is unclear whether ...

Novel approaches for correcting gene expression insufficiency

A new molecular technology capable of binding to mRNA and regulating gene expression may offer a new avenue for treating diseases caused by haploinsufficiency, or the absence of one functional gene copy, according to a study ...

Scientists reveal how epigenetic changes in DNA are interpreted

A new study in Science from Karolinska Institutet maps out how different DNA-binding proteins in human cells react to certain biochemical modifications of the DNA molecule. The scientists report that some 'master' regulatory ...
