The melting Arctic is not the source for less saline Nordic Seas. It is the Gulf Stream that has provided less salt. A new study documents that the source of fresher Nordic Seas since 1950 is rooted in the saline … Continue reading
A bright orange poison dart frog with a unique call has been discovered in Donoso, Panama. Because this new frog species appears to be found in only a very small area, habitat loss and collecting for the pet trade are … Continue reading
Hunting from a distance of 27,000 light years, astronomers have discovered an unusual carbon-based molecule contained within a giant gas cloud in interstellar space. The discovery suggests that the complex molecules needed for life may have their origins in interstellar … Continue reading
Each year 2.5 million children die worldwide because they do not receive life-saving vaccinations at the appropriate time. Now researchers are developing a fingerprint-based recognition method to track vaccination schedules for infants and toddlers, which will increase immunization coverage and … Continue reading
In the past 600 years off the California coast, occasional episodes of diminished ocean upwelling that cause fish populations to crash have occurred naturally. The poor yearly fish harvests seen in the last 60 years aren’t any worse in severity … Continue reading
Concrete is the world’s most-used construction material, and a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse-gas emissions. Now a new study suggests a way in which those emissions could be reduced by more than … Continue reading
Engineers have developed and successfully demonstrated the value of a simple pulley mechanism to improve hand function after surgery. The device, tested in cadaver hands, is one of the first instruments ever created that could improve the transmission of mechanical … Continue reading
New research suggests that people who notice their memory is slipping may be on to something. The research appears to confirm that self-reported memory complaints are strong predictors of clinical memory impairment later in life.
Geobiologists shed new light on multicellular fossils from a time 60 million years before a vast growth spurt of life known as the Cambrian Explosion occurred on Earth.
Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down plant cell walls for the production of next-generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine, researchers … Continue reading
Plasma bubbles may have contributed to communications outages during the 2002 battle of Takur Ghar in Afghanistan. A new model could help predict the impact of such bubbles on future military operations.
Astronomers have observed what may be the first-ever signs of windy weather around a T Tauri star, an infant analog of our own Sun. This may help explain why some T Tauri stars have disks that glow weirdly in infrared … Continue reading
Many native species have vanished from tropical islands because of human impact, but scientists have discovered how fossils can be used to restore lost biodiversity. The key lies in organic materials found in fossil bones, which contain evidence for how … Continue reading
For the first time, scientists have discovered how to produce ultra-thin ‘diamond nanothreads’ that promise extraordinary properties, including strength and stiffness greater than that of today’s strongest nanotubes and polymers. The threads have a structure that has never been seen … Continue reading
Researchers have found new adhesives based on mussel proteins could be useful for naval or medical applications. To create their new waterproof adhesives, researchers engineered bacteria to produce a hybrid material that incorporates naturally sticky mussel proteins as well as … Continue reading
