No Redoubt: Volcanic eruption forecasting improved

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.

Bioengineers create rubber-like material bearing micropatterns for stronger, more elastic hearts

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.

Comparing proteins at a glance

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

Feast clue to smell of ancient earth

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.

Microchip proves tightness provokes precocious sperm release

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

Movement of pyrrole molecules defy 'classical' physics

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 rare alpine bacteria, researchers identify one of alcohol's key gateways to the brain

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.

Einstein was right -- So far

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

The Earth's center is 1,000 degrees hotter than previously thought

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

Piezoelectric 'taxel' arrays convert motion to electronic signals for tactile imaging

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.

Rethinking early atmospheric oxygen

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.

Battery and memory device in 1

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

Nanowires grown on graphene have surprising structure

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.
