Ice-cold methods decode bacterial infection systems
When attacking body cells, bacteria, such as salmonellae or Yersinia (plague pathogens), inject specific bacterial proteins through hollow, syringe-like structures – called injectisomes – into the host ...
Two for the price of one: Single-molecule microscopy simultaneously monitors protein structure and function
Intracellular ABC transporters enable leaf beetle larvae to accumulate defensive precursors when feeding
Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by ...
Who's patenting whose genome?
An international project has developed a free and open public resource that will bring much-needed transparency to the murky and contentious world of gene patenting.
How hummingbirds evolved to fly at high altitude
(Phys.org) —High up in the Andes, numerous species of hummingbirds are thriving despite low levels of oxygen.
Proteins' passing phases revealed
A new method to identify previously hidden details about the structures of proteins may speed the process of novel drug design, according to scientists at Rice University.
Scientists stitch up photosynthetic megacomplex
When sunlight strikes a photosynthesizing organism, energy flashes between proteins just beneath its surface until it is trapped as separated electric charges. Improbable as it may seem these tiny hits of ...
Difficult dance steps: Team learns how membrane transporter moves
(Phys.org) —Researchers have tried for decades to understand the undulations and gyrations that allow transport proteins to shuttle molecules from one side of a cell membrane to the other. Now scientists ...
Scientists prove X-ray laser can solve protein structures from scratch
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
Reducing large proteins to small molecules yields more affordable drugs
(Phys.org) —University of Queensland researchers have pioneered a drug development technique that could pave the way for a new class of low-cost medicines.
Two human proteins found to affect how 'jumping gene' gets around
Using a new method to catch elusive "jumping genes" in the act, researchers have found two human proteins that are used by one type of DNA to replicate itself and move from place to place. The discovery, ...
Most detailed picture ever of key part of hepatitis C
Scientists at The Scripps Research Institute (TSRI) have determined the most detailed picture yet of a crucial part of the hepatitis C virus, which the virus uses to infect liver cells. The new data reveal ...
Scientists unearth secrets of Perigord truffles, the culinary 'black diamond'
Just in time for the holidays when cooks in France and elsewhere will be slipping bits of the coveted black Périgord truffle under their turkeys' skin for a luxurious flavor, scientists are revealing the ...
Key protein responsible for controlling communication between brain cells identified
Scientists are a step closer to understanding how some of the brain's 100 billion nerve cells co-ordinate their communication. The study is published today in the journal Cell Reports.
