In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study from researchers. New seismology data are confirming that such narrow jets don't actually exist.
Depictions of animals in ancient Egyptian artifacts have helped scientists assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years. A new analysis of this record shows that species extinctions, probably caused by a drying climate and growing human population in the region, have made the ecosystem progressively less stable.
Australian researchers are working with archaeologists, anthropologists and the Northern Territory's Jawoyn community to chemically analyze ancient rock art and uncover its secrets.
Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water. Now, an analysis shows that a different desalination technology called electrodialysis, powered by solar panels, could provide enough clean, palatable drinking water to supply the needs of a typical village.
Hundreds of children in about a dozen states have been sickened by a severe respiratory illness that public health officials suspect may be caused by an uncommon virus similar to the germ that causes the common cold.
With climate change still a political minefield across the nation despite the strong scientific consensus that it's happening, some community leaders have hit upon a way of preparing for the potentially severe local consequences without triggering explosions of partisan warfare: just change the subject.
Scientists have married two unconventional forms of carbon– one shaped like a soccer ball, the other a tiny diamond– to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.
A revolutionary nanotechnology method could help improve the development of new medicine and reduce costs. Researchers have developed a new screening method that makes it possible to study cell membrane proteins that bind drugs, such as cannabis and adrenaline, while reducing the consumption of precious samples by a billion times.
A well-known biologist once theorized that many roads led to Rome when it comes to two distantly related organisms evolving a similar trait. But, a new paper suggests that when it comes to evolving some traits– especially simple ones– there may be a shared gene, one road, that’s the source.
Raw honey has been used against infections for millennia. So what is the key to its’ antimicrobial properties? Researchers have identified a unique group of 13 lactic acid bacteria found in fresh honey, from the honey stomach of bees. The bacteria produce a myriad of active antimicrobial compounds.
Optical Surfaces has introduced smaller-diameter (25 to 60 mm) Reflective Beam Expanders for space-restricted applications, such as high-power lasers and multi-wavelength interferometry. Reflective beam expanders are aspheric mirror-based devices offering either beam expansion or reduction capabilities.
Waters’ XevoG2-XS mass spectrometer is a high-performance benchtop quadrupole time-of-flight (QTof) mass spectrometer.
AB SCIEX’s TripleTOF 6600 high-resolution, accurate-mass system brings enhanced power to scientists developing biotherapeutics. Delivering the broad mass and dynamic range required for these compounds, the instrument offers the unique ability to address biomolecules and their complexities quickly and easily.
The uDAWN from Wyatt Technology is a multi-angle light scattering (MALS) detector that can be coupled to any UHPLC system in order to determine absolute molecular weights and sizes of polymers, peptides and proteins or other biopolymers directly, without resorting to column calibration or reference standards.
The Zetasizer Helix from Malvern Instruments is a powerful tool for early stage biopharmaceutical development that enables the detailed study of mechanisms of protein aggregation.
