Atomic clock may help with more precise measurements Physicists have created an atomic clock that is so accurate it won’t lose a second for 300 billion years. Researchers say the clock’s precision will help them better understand difficult to measure things as gravitational waves and dark matter. Space.com Map charts Milky Way’s leftovers from galaxy […]

Nanothreads are one-dimensional nanomaterials composed of a primarily sp 3 hydrocarbon backbone, typically formed through the compression of small molecules to high pressures. In 2015, it was found that the slow room-temperature compression of benzene produced crystalline , one-dimensional polymers composed of diamond-like bonds. These diamondoid materials that border nanotubes and polymers are predicted to […]
Oviraptorosaurs are a group of birdlike dinosaurs that were part of the ancestral dinosaur lineage that later gave rise to birds. Oviraptorosaurs walked on two legs, had a powerful toothless beak and were covered in feathers. One of the first known species, Oviraptor philoceratops, was discovered in the 1920s when a skeleton was uncovered alongside […]
Imagine you are enjoying a peaceful summer evening at the shore of the Mediterranean Sea. Not far from you, some kids are piling up sand with a shovel. They do not care about the shape the pile is taking, so one would expect just an amorphous pile of sand. To your astonishment, that is not […]
Ryugu sample reveals asteroid’s inner secrets Samples returned from the Ryugu asteroid by the Hayabusa2 spacecraft are yielding information about materials found just beneath the object’s surface. “The variations in physical properties among the pebbles and sand, which were not expected before spacecraft arrival at the asteroid, reflect the geological history of Ryugu,” scientists wrote […]
Twistology could be the study of unexpected changes or developments in stories or situations, from coups d’état to the fatherhood of Darth Vader. In condensed matter physics there is something similar, although the preferred name is twistronics (from twist and electronics). It is understood as the study of how the angle (the twist) between layers […]
Two years of battling COVID-19 has been bad news for tuberculosis (TB) programmes. Respiratory clinicians and researchers have had their time and focus directed elsewhere. And TB has taken advantage. In 2021, the number of TB deaths rose for the first time in over a decade. The barriers caused by lockdowns and overstretched healthcare systems […]
C ardiovascular diseases currently form the most important class of non-contagious diseases and a leading cause of mortality in industrialized nations . Specifically, coronary heart disease is the first cause of death among the cardiovascular diseases . The myocardial infarction (MI), commonly known as a “heart attack”, occurs when blood flow decreases or stops in […]
Chromosome study hints at early evolution of animals Chromosome changes that took place about 800 million years ago have been examined and used to find genes that may have been present in the earliest moments of animal life. Researchers viewed genomes at the chromosome level to study what they call genome tectonics to find nearly […]
Inorganic and organic light-emitting diodes (ILEDs and OLEDs, respectively) are quickly replacing incandescent light bulbs and compact fluorescent lamps. The reasons for the success are easy to understand. For instance, ILEDs’ performance has met the market requirements for in-/out-door applications with single-point sources. However, ILEDs cannot be considered a sustainable solution as of today. One […]
