Forecasting volcanic eruptions with success is heavily dependent on recognizing well-established patterns of pre-eruption unrest in the monitoring data. But in order to develop better monitoring procedures, it is also crucial to understand volcanic eruptions that deviate from these patterns.
A team of bioengineers at Brigham and Women's Hospital (BWH) is the first to report creating artificial heart tissue that closely mimics the functions of natural heart tissue through the use of human-based materials. Their work will advance how clinicians treat the damaging effects caused by heart disease, the leading cause of death in the United States.
A revolutionary X-ray analytical technique that enables researchers at a glance to identify structural similarities and differences between multiple proteins under a variety of conditions has been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab). As a demonstration, the researchers used this technique to gain valuable new insi
Tiny 1,900 million-year-old fossils from rocks around Lake Superior, Canada, give the first ever snapshot of organisms eating each other and suggest what the ancient Earth would have smelled like.
Sperm cell release can be triggered by tightening the grip around the delivery organ, according to a team of nano and microsystems engineers and plant biologists at the University of Montreal and Concordia University. Concordia's nanobiotech team devised a microchip that enabled the University of Montreal biologists to observe what happened when pollen tubes – the sperm delivery tools used by plan
New research shows that movement of the ring-like molecule pyrrole over a metal surface runs counter to the centuries-old laws of 'classical' physics that govern our everyday world.
Thanks to a rare bacteria that grows only on rocks in the Swiss Alps, researchers at The University of Texas at Austin and the Pasteur Institute in France have been the first to identify how alcohol might affect key brain proteins.
An international team has discovered an exotic double object that consists of a tiny, but unusually heavy neutron star that spins 25 times each second, orbited every two and a half hours by a white dwarf star. The neutron star is a pulsar that is giving off radio waves that can be picked up on Earth by radio telescopes. Although this unusual pair is very interesting in its own right it is also a u
With the help of a solitary sea squirt, scientists have resolved the longstanding puzzle of the crystal structure of vaterite, an enigmatic geologic mineral and biomineral.
Scientists have determined the temperature near the Earth's centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. The scientis
Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.
A research team of biogeochemists at the University of California, Riverside has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth history, and its relationship to the sulfur cycle.
Resistive memory cells (ReRAM) are regarded as a promising solution for future generations of computer memories. They will dramatically reduce the energy consumption of modern IT systems while significantly increasing their performance. Unlike the building blocks of conventional hard disk drives and memories, these novel memory cells are not purely passive components but must be regarded as tiny b
When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy.
In a few places on Earth, sand "sings" as it falls down dunes, making a low droning sound that lies within the bottom half of a cello's musical range. For centuries the eerie humming in deserts mesmerized visitors. In 2009, researchers found that the sound is created by vibrations of the sand grains that avalanche down the dunes. But how do the sands create multiple notes?
Judge hands out sentences of 6-year imprisonment to seven scientists and engineers who met ahead of the 2009 L'Aquila earthquake
The U.S. Geological Survey got close enough to shoot video inside Hawaii's Kilauea volcano, which is flowing at the highest levels ever recorded. Scott Pelley reports.
Killing drug lords gets headlines, but complexity analysis suggests they are the wrong people to target to bring down a cartel
The most powerful star explosions in the universe can blast out far more freshly made radioactive titanium than has been suspected: up to 100 times the mass of the Earth, researchers say.
Drinking mechanism depends on shape of flower
Geometrical theorems that used to hang from Shinto and Buddhist shrines were both religious offerings and public entertainment
Fluid dynamicists have developed a trick to make droplets sit on water indefinitely.See it in action in this video
If DNA has a half-life that suggests the molecules can survive far longer than anyone thought, maybe 6 million years
If the cosmos is a numerical simulation, there ought to be clues in the spectrum of high energy cosmic rays, say theorists
Although Einstein's theories suggest nothing can move faster than the speed of light, two scientists have extended his equations to show what would happen if faster-than-light travel were possible.
In 1949, a teacher at Eton, a British boarding school, belittled John Gurdon's dreams of becoming a scientist as "quite ridiculous." This week, Gurdon's breakthrough in reprogramming cells received the Nobel Prize for medicine.
Because about half of all drugs act on the receptors that let humans sense their environment, the scientists' work has been incredibly important for the development of pharmaceuticals.
Prize honors breakthroughs in quantum optics
Serge Haroche of France and David Wineland of the United States have been honored for their work on the interaction between life and matter — in particular, the "fundamental interactions between light particles and matter."
