Time-lapse video highlights supernova flare NASA and the European Space Agency have released a time-lapse video of a supernova flaring culled from Hubble Space Telescope observations. The video, created from about a year’s worth of Hubble observations, shows a white dwarf exploding then fading away in the NGC 2525 galaxy about 70 million light-years from […]
Auranofin is a gold (Au) salt classified by the World Health Organization as an antirheumatic agent. It was approved for the treatment of rheumatoid arthritis in 1985, but is no longer a first-line treatment due to its adverse effects on a long-term basis. But the drug is important in another way. The discovery that auranofin […]
Chronic diseases are already having and will continue to have not only profound economic, social and individual consequences but also a major impact on the use of health resources and design of new care processes. Chronic obstructive pulmonary disease (COPD) is a case on point. COPD is airflow limitation caused by an inflammatory response to […]
Symmetries play a fundamental role in Physics, and more specifically in Quantum Physics. It is well known that symmetries lead to degeneracy and to conserved currents in closed quantum systems (meaning that they do not interact with an environment). In the more realistic scenario of Open Quantum Systems (meaning that the quantum system does interact […]
Mouse mom’s microbiome may affect her young A mouse mother’s gut microbes may play an important role in offspring’s brain development, according to findings published in Nature. Particular gut microbes produce metabolites that travel to the fetuses’ brains, affecting the growth of axons, which act as nerve cell signal transmitters. Science News Homo sapiens Y […]
Many problems in science and engineering involve understanding how quickly a physical system transitions between distinguishable states and the energetic costs of advancing at a given speed. While theories such as thermodynamics and quantum mechanics put fundamental bounds on the dynamical evolution of physical systems, the form and function of the bounds differ. Rudolf Clausius’s […]
I would like to think that the first work devoted to something that we might call ‘the problem of scientific method’ was written by Democritus (around 460-370 BC), the author the philosophical systems of Plato and Aristotle were constructed against , and whose ideas were so revolutionary that it seems that nobody in the last […]
We all know some of the symptoms of sleep deprivation: bad mood, tiredness…but when bad comes to worst, this lack of sleep can even lead to death. A recently published article by neuroscientists at Harvard Medicine School have shown, in flies, that lack of sleep might be killing from the gut. Because flies share many […]
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 […]
