Antibiotics 2.0: The atomic structure and mechanism of mammalian host-defense peptides
Melanin from Jurassic-era mollusk could lead to new tool for cancer diagnosis
'Global positioning' for molecules
In everyday life, the global positioning system (GPS) can be employed to reliably determine the momentary location of one en route to the desired destination. Scientists from the Institute of Physical and ...
'Quadruple helix' DNA discovered in human cells
In 1953, Cambridge researchers Watson and Crick published a paper describing the interweaving 'double helix' DNA structure - the chemical code for all life. Now, in the year of that scientific landmark's 60th Anniversary, ...
Chemists crack the chirality code
Chemists at Trinity College Dublin have cracked the chirality code. The chirality (or left/right-handed asymmetry) of amino acids presented a long-standing challenge that complicated efforts to create certain types of proteins, ...
Into the breach: Transporting molecular cargo through algal cell walls
Study confirms controversial nitrite hypothesis
Understanding how nitrite can improve conditions such as hypertension, heart attack and stroke has been the object of worldwide research studies. New research from Wake Forest University has potentially moved the science ...
Two for the price of one: Single-molecule microscopy simultaneously monitors protein structure and function
The road also taken: Alternative and hidden pathways in biological electron transfer
Scientists solve mystery of the eye
Scientists find key to vitamin A metabolism
Researchers at Case Western Reserve University School of Medicine have uncovered the mechanism that enables the enzyme Lecithin: retinol acyltransferase (LRAT) to store vitamin A—a process that is indispensable ...
Where no lab has gone before: Single-Molecule Electrokinetic Traps
Scientists create first living organism that transmits added letters in DNA 'alphabet'
Scientists at The Scripps Research Institute (TSRI) have engineered a bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature. The cells of this unique bacterium ...
Chemists create 'artificial chemical evolution' for the first time
Scientists have taken an important step towards the possibility of creating synthetic life with the development of a form of artificial evolution in a simple chemistry set without DNA.
