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 […]
“ The dose makes the poison!” This adage, attributed to Paracelsus, explains a basic principle of toxicology: a substance can produce a harmful effect only if it reaches a certain “toxic” concentration. [ 1 ] In reverse, it also means that a substance is not harmful below this toxic dose, and can even be vitally […]
The question of the arrow of time has been on the table for centuries. The microscopic laws that determine the behaviour of matter (both in the classical and quantum regimes) are reversible. By seeing a video of a billiard board, with just a few balls, you will not be able to determine if the video […]
The discovery of superconductivity in 2D films dates back over 80 years. Initially, these were 2D metallic films deposited on inert substrates, but in recent times more exotic 2D systems have exhibited superconducting properties, such as the surface of topological insulators or twisted bilayer graphene. Superconductivity is caused by the interactions between atomic vibrations (phonons) […]
