The earliest traces of life on Earth—researchers explore carbon in 3.9-billion-year-old Canadian rocks
The isotopic composition of carbon in iron formations from the Saglek-Hebron Complex in Nunatsiavut (northern Labrador) has been seen as evidence of the earliest traces of life on Earth. But a new study by the University of Ottawa, Carleton Universit.....»»
Miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection rivals lab-based systems
Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. H.....»»
Distant blazar discovery supports rapid black hole formation in the early universe
Astronomers have discovered an important piece of the puzzle of how supermassive black holes were able to grow so quickly in the early universe: a special kind of active galactic nucleus so distant that its light has taken more than 12.9 billion year.....»»
Massive volcanic eruptions did not cause the extinction of dinosaurs, say climate scientists
Massive volcanic eruptions on the Indian peninsula have long been proposed as an alternative cause for the demise of the dinosaurs. This phase of active volcanism took place in a period just before Earth was struck by a meteorite, 66 million years ag.....»»
Rocket-inspired reaction yields carbon with record surface area
Using a chemical reaction inspired by rocket fuel ignition, Cornell researchers have engineered a nanoporous carbon with the highest surface area ever reported, a breakthrough that is already proving beneficial for carbon-dioxide capture and energy s.....»»
NASA finds "sideways" black hole using legacy data and new techniques
NASA researchers have discovered a perplexing case of a black hole that appears to be "tipped over," rotating in an unexpected direction relative to the galaxy surrounding it. That galaxy, called NGC 5084, has been known for years, but the sideways s.....»»
Nonlinear "skin effect" unveiled in antiferromagnetic materials
A team of researchers has identified a unique phenomenon, a "skin effect," in the nonlinear optical responses of antiferromagnetic materials. The research, published in Physical Review Letters, provides new insights into the properties of these mater.....»»
Study finds aquatic vegetation removal benefits health and economy
Turning aquatic vegetation near agricultural land into compost simultaneously eradicates habitat for disease-carrying snails while improving agricultural output and increasing incomes in northern Senegal, Cornell researchers have found......»»
Researchers identify 35 new lizard species on Caribbean islands
A new scientific study from Temple University's College of Science and Technology (CST) has identified 35 new species of forest lizards, all from islands in the Caribbean. However, that same study has also found that these species of lizards won't be.....»»
New radar algorithm reveals hidden dance of ionospheric plasma
At night, charged particles from the sun caught by Earth's magnetosphere rain down into the atmosphere. The impacting particles rip electrons from atoms in the atmosphere, creating both beauty and chaos. These high-energy interactions cause the north.....»»
Researchers explore, sample and interpret lunar volatiles in polar cold traps
The moon has both a South and North Pole, but just how cold are they? For context, Antarctica's coastal temperatures average around 14°F (-10°C), while the interior drops to -76°F (-60°C), making Earth's South Pole one of the coldest places on th.....»»
Astronaut-on-a-chip: Multi-organ tissue chips simulate space radiation"s impact on human health
As astronauts venture further into space, their exposure to harmful radiation rises. Researchers from Columbia University are simulating the effects of space radiation here on Earth to determine its impact on human physiology using multi-organ tissue.....»»
New York man finds mastodon jaw while gardening in his backyard
Scholars are hailing the discovery of a fossilized mastodon jaw discovered by a man who spotted two giant teeth while gardening at his upstate New York home this year......»»
New method maps hundreds of proteins in cell nuclei simultaneously
Caltech researchers have developed a new method to map the positions of hundreds of DNA-associated proteins within cell nuclei all at the same time. The method, called ChIP–DIP (Chromatin ImmunoPrecipitation Done In Parallel), is a versatile tool f.....»»
Researchers address material challenges to make commercial fusion power a reality
Imagine if we could take the energy of the sun, put it in a container, and use it to provide green, sustainable power for the world. Creating commercial fusion power plants would essentially make this idea a reality. However, there are several scient.....»»
Old moon, young crust: Violent volcanism may mean the moon is much older than previously thought
After its formation, the moon may have been the scene of such immense volcanic activity that its entire crust melted several times and was completely churned through. At that time, the moon orbited significantly closer to Earth than today. The result.....»»
Comprehensive analysis reveals hidden genomic evolution of brown algae
Covering over 70% of Earth's surface, the oceans are home to countless life forms that maintain ecological balance and support human well-being. Among these, brown algae (Phaeophyceae) play a crucial role in sustaining coastal habitats, supporting ma.....»»
