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.
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 ...
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.
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, ...
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.
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.
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 ...
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 ...
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.
Progress against antibiotic-resistant bacterium with wewly ID'd protein
(Phys.org) —Researchers have made inroads into tackling a bacterium that plagues hospitals and is highly resistant to most antibiotics. They determined the 3-D structure and likely function of a new protein ...
Researchers find misfolded proteins are capable of forming tree-like aggregates
A method by Rice University researchers to model the way proteins fold – and sometimes misfold – has revealed branching behavior that may have implications for Alzheimer's and other aggregation diseases.
Two-way traffic enable proteins to get where needed, avoid disease
It turns out that your messenger RNA may catch more than one ride to get where it's going.
Bonding together to fight HIV
A collaborative team led by a Northeastern University professor may have altered the way we look at drug development for HIV by uncovering some unusual properties of a human protein called APOBEC3G (A3G).
Tiny crystals could revolutionize structural biology studies
For structural biologists, the first step in determining a protein's precise molecular structure is often the hardest: coaxing the protein to grow into the orderly, three-dimensional crystals that are the ...
