Constituting over 78 % of the air we breathe, nitrogen is the element found the most often in its pure form on earth. The reason for the abundance of elemental nitrogen is the incredible stability and inertness of dinitrogen (N2), a molecule comprising two nitrogen atoms and the form in which most nitrogen exists. Only in very harsh environments, such as in the ionosphere, can dinitrogen be assembled into longer nitrogen chains, forming N4 ions with very short lifetimes.
Researchers developed the seats to measure biometrics during 'natural' processes With 1 million new cases of congestive heart failure diagnosed each year, a revolutionary product is making it easier for hospitals to monitor patients with the condition in the comfort of their own homes.
Periodontitis affects nearly half of Americans ages 30 and older, and in its advanced stages, it could lead to early tooth loss or worse. Recent studies have shown that periodontitis could also increase risk of heart disease and Alzheimer's disease.
Rutgers study shows how bacteria in wastewater plants transform widely used chemicals. When you flush the toilet, you probably don't think about the traces of the medicine and personal care products in your body that are winding up in sewage treatment plants, streams, rivers, lakes, bays and the ocean.
A slowdown in image processing speeds up our perception of time passing as we age DURHAM, N. C. -- A Duke University researcher has a new explanation for why those endless days of childhood seemed to last so much longer than they do now--physics.
X-ray research at Berkeley Lab reveals samples are a new state of matter The realization of so-called topological materials - which exhibit exotic, defect-resistant properties and are expected to have applications in electronics, optics, quantum computing, and other fields - has opened up a new realm in materials discovery.
The destructive power of storms can only worsen in the future as the Earth continues to warm up. The crisis in the climate is driving the ocean levels to rise and it only makes everything else worse.
A newly discovered parasitic cycle, in which ocean bacteria keep phytoplankton on an energy-sapping treadmill of nutrient detoxification, may offer a preview of what further ocean warming will bring.
In the Atlantic Ocean, a giant 'conveyor belt' carries warm waters from the tropics into the North Atlantic, where they cool and sink and then return southwards in the deep ocean.
CAMERA, the University of Bath's motion capture research centre, has collaborated with the Interactive arm of Aardman on a BBC virtual reality documentary about the story of twin sisters whose lives were torn apart by a terrible accident.
Hayabusa2 helps researchers understand ingredients for life in early solar system The first data received from the Hayabusa2 spacecraft in orbit of asteroid Ryugu helps space scientists explore conditions in the early solar system.
New Purdue University technology designed to help clean, purify water used in oil refinement About 2. 5 billion gallons of produced water, a byproduct from the oil refinery and extraction process, is generated each day in the United States.
The ecological bio-production of xylitol and cellulose nanofibers using modified yeast cells, from material produced by the paper industry has been achieved by a Japanese research team.
Freshwater biodiversity is rapidly declining worldwide, and nature-based solutions which increase the resilience of ecological communities are becoming increasingly important in helping communities prepare for the unavoidable effects of climate change.
Researchers from the University of British Columbia and McMaster University have developed what could be the bone implant material of the future: an airy, foamlike substance that can be injected into the body and provide scaffolding for the growth of new bone.
Nanoscale patterning could enable precise manipulation of objects on many scales Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects' surfaces.
Study may open the door to developing drug therapies or even gene therapies for alcohol addiction Scientists at Scripps Research have found that they can reverse the desire to drink in alcohol-dependent rats--with the flip of a switch.
"Frustration" plus a pulse of laser light resulted in a stable "supercrystal" created by a team of researchers led by Penn State and Argonne National Laboratory, together with University of California, Berkeley, and two other national laboratories.
Caregivers design robots that increase joyful moments and reduce emotional stress Building robots that can help people with dementia has been a longtime goal for roboticists.
The University of Cincinnati created the world's first continuous-monitoring device that tests sweat as effectively as blood but in a noninvasive way and over many hours
Dysregulation of the signaling pathway known as the beta-catenin-dependent Wnt can also cause embryo malformation and contribute for the development of breast and cervical cancer.
An interface system that uses augmented reality technology could help individuals with profound motor impairments operate a humanoid robot to feed themselves and perform routine personal care tasks such as scratching an itch and applying skin lotion. The web-based interface displays a "robot's eye view" of surroundings to help users interact with the world through the machine.
The largest-ever study of ancient DNA from the Iberian Peninsula (Spain and Portugal) suggests that the Iberian male lineages were almost completely replaced between 4,500 and 4,000 years ago by newcomers originating on the Russian steppe
