No knots in known RNA structures
It had never been verified before: unlike other biopolymers, RNA, the long strand that is 'cousin' to DNA, tends not to form knots. The observation has been published in the journal PNAS by a research team o ...
Pinpointing the magnetic moments of nuclear matter
A team of nuclear physicists has made a key discovery in its quest to shed light on the structure and behavior of subatomic particles.
New research predicts when, how materials will act
In science, it's commonly known that materials can change in a number of ways when subjected to different temperatures, pressures or other environmental forces.
Molecular mouse-trap technique sheds light on key cell processes
Scientists have shed new light on the fundamental biological process of cell division, thanks to an emerging analytical method.
Geomicrobiologists show how microbial fossils resist the conditions of rock formation
Since life originated on Earth between 3.8 and 3.9 Ga ago, microorganisms have significantly shaped and influenced the chemistry of Earth's surface and subsurface environments. Reconstructing the evolution ...
Dolphins set up home in the Mediterranean after the last Ice Age
The bottlenose dolphin only colonised the Mediterranean after the last Ice Age - about 18,000 years ago – according to new research.
An unusual form of carbon ring structure identified in a family of doughnut-like macrostructures
The source of the peculiar stability of the structures forming carbon nanotubes has been established by researchers from the RIKEN Elements Chemistry Laboratory.
Video: Earthquake research in Chile could shake up the field of seismology
Galo Valdebenito, a professor of seismic and structural dynamics and associate dean of engineering at Austral University, is developing tools so urban planners can better assess earthquake risks.
Progress toward the understanding of the galactic structure
Researchers at the Universidad Politécnica de Madrid and the Instituto de Astrofísica de Canarias are studying the evolution and formation of hundreds of close galaxies and have just published new scientific ...
The rarely understood ammonium carbonate monohydrate
New structural studies of the superficially simple ammonium carbonate monohydrate could shed light on industrial processes, biochemistry and even the interstellar building blocks of life.
Camels betray their best mates in 'Judas' trials
Murdoch University researchers have successfully trialled an approach to control feral camel numbers in Australia's outback whereby a single animal is used to betray the whereabouts of its companions.
Removing color from brown diamonds
Diamonds come in all colours with price tags to match - ice-white, blue and pink attract high prices and stones with brown hues the least. But now that brown diamonds can be heat-treated to remove the darker ...
New study reveals competition and replacement between two miocene shovel-tuskers
Dr. Wang Shiqi from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences and his colleagues recently studied two relatively primitive species of Protanancus, ...
Using soft X-ray emission spectroscopy to reveal the behavior of electrons associated with charging and discharging
Researchers have used soft X-ray emission spectroscopy to reveal the detailed electronic structure of a cathode (positive electrode) material when charging and discharging a lithium-ion battery.
