Scientists looking across human, fly and worm genomes find shared biology
Researchers analyzing human, fly, and worm genomes have found that these species have a number of key genomic processes in common, reflecting their shared ancestry. The findings, appearing Aug. 28, 2014, in ...
Nanotech-enabled moisturizer speeds healing of diabetic skin wounds
A new high-tech but simple ointment applied to the skin may one day help diabetic patients heal stubborn and painful ulcers on their feet, Northwestern University researchers report.
DNA 'spool' modification affects aging and longevity
Research on a modified protein around which DNA is wrapped sheds light on how gene regulation is linked to aging and longevity in nematodes, fruit flies and possibly humans.
Sugar key to cellular protein protection and viability
A Simon Fraser University laboratory's breakthrough in understanding how a specialized sugar regulates protein levels in our cells could generate new targets for therapies to treat diseases caused by improper protein regulation. ...
We're all mammals – so why do we look so different?
It is easy to distinguish a mouse from a cow. But for members of the same class of mammal, where do such differences begin? In 2011, scientists discovered there were differences in cow and mice blastocysts, the ti ...
Proposed rules for drones envision routine commercial use (Update)
Small drones could become a familiar sight across the nation's skies if the government adopts proposals that are largely favorable to commercial use of the remote-controlled aircraft.
A first of its kind tool to study the histone code
University of North Carolina scientists have created a new research tool, based on the fruit fly, to help crack the histone code. This research tool can be used to better understand the function of histone proteins, which ...
US proposal seeks to head off Internet 'fast lanes' (Update)
The top US telecom regulator proposed Wednesday to regulate broadband Internet service providers as "public utility" carriers, in a renewed effort to enforce "net neutrality" rules.
Why is a dolphin not a cat? How repurposing non-coding elements in genome gave rise to great 'mammalian radiation'
New research shows how evolution has given rise to a rich diversity of species by repurposing functional elements shared by all mammals. Published in Cell by scientists at the European Bioinformatics Instit ...
Researchers identify natural plant compounds that work against insects
Each year millions of deaths result from diseases transmitted by insects. Insects are also responsible for major economic losses, worth billions of dollars annually, by damaging crops and stored agricultural products.

A protein-production tale of the tape: Separating poly(A)-tail length from translational efficiency
(Phys.org) —In higher animals, an embryo's protein production immediately after fertilization relies on messenger RNAs (mRNAs) inherited from the mother. But shortly thereafter, the tiny organism undergoes ...
Researchers tune in to protein pairs: Team quantifies how mutations affect cell signaling in bacteria
Rice University scientists have created a way to interpret interactions among pairs of task-oriented proteins that relay signals. The goal is to learn how the proteins avoid crosstalk and whether they can ...
Gene regulation differences between humans and chimpanzees more complex than thought
Changes in gene regulation have been used to study the evolutionary chasm that exists between humans and chimpanzees despite their largely identical DNA. However, scientists from the University of Chicago have discovered ...
