High-resolution images offer detailed look at stellar winds Astronomers used Chile’s ALMA Observatory to take high-resolution images of stellar winds around dying red giant stars, showcasing the winds’ unusual shapes. “Some stellar winds were disk-shaped, others contained spirals, and in a third group, we identified cones,” says Leen Decin, co-author of a study on the […]
Carbon monoxide (CO) oxidation (2CO + O2 → CO2) on platinum (Pt) group metal surfaces is the model heterogeneous gas/surface catalytic reaction. Pt itself is of the upmost importance as a catalyst for car exhaust cleaning or for the water gas shift reaction, whereas Pt crystal surfaces are model systems for investigating the catalytic CO […]
Since this will be a series of entries about something as weird as the ‘prehistory’ of philosophy of science, I think readers deserve a little explanation about what I do exactly mean by that. ‘Philosophy of science’, to begin with, is a topic that took its current status as an autonomous academic field (I mean […]
Body odor is present in all mammals, including of course humans. It has a clear genetic basis, although it is modulated by different conditions, both normal and pathological. Interestingly, although it is believed to have an important communicative function and to be involved in sexual attraction, body odor is considered unpleasant by most people, which […]
Oldest Neanderthal DNA found in Europe holds clues to Neanderthal life Mitochondrial DNA taken from a Neanderthal tooth found in a cave in Poland is giving researchers new clues about Neanderthal life in the region about 80,000 years ago. Tools found in the cave known as Micoquian give clues to the ways Neanderthals were adapting […]
The most famous conjecture in condensed-matter physics was proposed in 1935, when Hillard Huntington and Eugene Wigner calculated the properties of hydrogen squeezed to high density and pressure. They predicted that under pressures above 25 gigapascals (GPa), hydrogen would undergo a density-driven transition from an insulating, molecular solid to a conducting, atomic solid . In […]
It has been almost a decade since the promises of urban autonomous goods deliveries with Unmanned Aerial Vehicles (UAVs) started. However, the reality came to claim that it was not so easy. Main problems are based on short battery life, low load capacity and high economical cost of the carriage. Unmanned Aerial Systems (UAS) appeared […]
Amyloid plaques are a hallmark of some neurodegenerative diseases like Alzheimer’s or Parkinson’s. Even though the exact role of amyloid protein in the disease is not clear, being able to follow amyloid protein misfolding and plaque formation could be a step forward for the study of the disease. Now, Matthew Lew’s lab has developed a […]
Faraway star trio surrounded by 3 rings of dust and gas Three unusual rings of planet-forming gas and dust have been detected circling a trio of stars in the Orion constellation, about 1,300 light-years away, according to studies in Science and Astrophysical Journal Letters that have differing views on how the configuration came to be […]
Light emission from emitters is a valuable piece of information in a variety of sensing and detection techniques, capable of labeling physical and biological processes which occur in the proximity of the emitter. Furthermore, quantum technologies are currently exploiting the statistics of single-emitters light emission aiming at turning particular emitters into fundamental units to sustain […]
