Stanley Miller's forgotten experiments, analyzed
Stanley Miller, the chemist whose landmark experiment published in 1953 showed how some of the molecules of life could have formed on a young Earth, left behind boxes of experimental samples that he never ...
How a 'mistake' in a single-cell organism is actually a rewrite essential to life
A tiny but unexpected change to a segment of RNA in a single-cell organism looks a lot like a mistake, but is instead a change to the genetic information that is essential to the organism's survival.
Researchers one step closer to cocaine antidote
Researchers at the University of Copenhagen have gained new insight into the mechanism behind a protein dopamine transporter that could help in the development of future medical treatment against cocaine addiction.
How hummingbirds evolved to fly at high altitude

Introducing the multi-tasking nanoparticle
Kit Lam and colleagues from UC Davis and other institutions have created dynamic nanoparticles (NPs) that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles ...
Light scattering on dust holds clues to habitability
We are all made of dust. Dust particles can be found everywhere in space. Disks of dust and debris swirl around and condense to form stars, planets and smaller objects like comets, asteroids and dwarf planets. ...
Clay may have been birthplace of life, new study suggests
Clay, a seemingly infertile blend of minerals, might have been the birthplace of life on Earth. Or at least of the complex biochemicals that make life possible, Cornell University biological engineers report ...
Single mutation gives virus new target
In a new study published online in the journal PLOS Pathogens, an international team of scientists showed that by swapping a single amino acid they could change the sugar to which the human BK polyomavirus will b ...
Nanoshell shields foreign enzymes used to starve cancer cells from immune system
(Phys.org) —Nanoengineers at the University of California, San Diego have developed a nanoshell to protect foreign enzymes used to starve cancer cells as part of chemotherapy. Their work is featured on ...
Chemist devises optical imaging technique to unlock the mystery of memory
(Phys.org) —In the search to understand memory, Wei Min is looking at cells at the most basic level, long before the formation of neurons and synapses. The assistant professor of chemistry studies the synthesis ...
