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.
Experiment and theory unite at last in debate over microbial nanowires
Scientific debate has been hot lately about whether microbial nanowires, the specialized electrical pili of the mud-dwelling anaerobic bacterium Geobacter sulfurreducens, truly possess metallic-like conduc ...
Protein mimic shows promise as tissue engineering glue
Researchers have demonstrated the potential of a "synthetic protein mimic" to promote the adhesion of brain cells in a laboratory setting. This feat could help overcome a major challenge in nerve tissue engineering.
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.
OSKM stoichiometry determines iPS cell reprogramming
Researchers at Kyoto University's Center for iPS Cell Research and Application discover a simple way to increase the production of induced pluripotent stem cells. A major hurdle in reprogramming science is ...
Amino acids key to new gold leaching process
Curtin University scientists have developed a gold and copper extraction process using an amino acid–hydrogen peroxide system, which could provide an environmentally friendly and cheaper alternative to ...
Scientists discover new molecule from local herb with potential for drug development
Scientists at Nanyang Technological University (NTU Singapore) have discovered a new molecule which can join together chains of amino acids – the building blocks of protein.
Space agency says Philae completes primary mission
The pioneering lander Philae completed its primary mission of exploring the comet's surface and returned plenty of data before depleted batteries forced it to go silent, the European Space Agency said Saturday.
No signals heard from comet lander Saturday
The European Space Agency received no signals from the Philae lander Saturday morning during a scheduled effort to establish communication, the mission chief said.
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 ...
New microscopy technique allows mapping protein synthesis in living tissues and animals
Researchers at Columbia University have made a significant step toward visualizing complex protein metabolism in living systems with high resolution and minimum disturbance, a longstanding goal in the scientific ...
What makes the feather soar
Dinosaurs may have gone extinct some 66 million years ago, but that's hardly the end of their story. One group of their modern-day progeny, the class Avia—namely, birds—is a spectacular evolutionary success ...
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. ...
