In the United States, nearly every pediatric doctor’s visit begins with three measurements: weight, height and head circumference. Compared to average growth charts of children across the country, established in the 1970s, a child’s numbers can confirm typical development or provide a diagnostic baseline to assess deviations from the curve.Continuar Leyendo
A scientist from the Division of Quantum Condensed Matter Physics at the University of Tsukuba has formulated a new theory of superconductivity. Based on the calculation of the «Berry connection,» this model helps explain new experimental results better than the current theory. The work may allow future electrical grids toContinuar Leyendo
It is believed to be involved in the development of chronic inflammatory intestinal diseases, to trigger diabetes, to be responsible for obesity, even neurological diseases such as multiple sclerosis and Parkinson’s could have their causes here — not to mention depressions and autistic disorders. We are talking about the microbiomeContinuar Leyendo
Ever since the 1986 discovery that copper oxide materials, or cuprates, could carry electrical current with no loss at unexpectedly high temperatures, scientists have been looking for other unconventional superconductors that could operate even closer to room temperature. This would allow for a host of everyday applications that could transformContinuar Leyendo
Current clinical interventions for infectious diseases are facing increasing challenges due to the ever-rising number of drug-resistant microbial infections, epidemic outbreaks of pathogenic bacteria, and the continued possibility of new biothreats that might emerge in the future. Effective vaccines could act as a bulwark to prevent many bacterial infections andContinuar Leyendo
Australian scientists researching how our immune system responds to COVID-19 have revealed that those infected by early variants in 2020 produced sustained antibodies, however, these antibodies are not as effective against contemporary variants of the virus. Sydney, July 08, 2021.- The research is one of the world’s most comprehensive studiesContinuar Leyendo
People who receive mRNA COVID-19 vaccines are up to 91 percent less likely to develop the disease than those who are unvaccinated, according to a new nationwide study of eight sites, including Salt Lake City. For those few vaccinated people who do still get an infection, or «breakthrough» cases, theContinuar Leyendo
Palomar 5 is a unique star cluster. This is firstly because it is one of the «fluffiest» clusters in the halo of our Galaxy, with the average distance between the stars being a few light-years, comparable to the distance from the Sun to the nearest star. Secondly, it has aContinuar Leyendo
A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet’s core and crust). For decades, scientists argued that hit-and-run collisions with other bodies during the formation of our solar system blew away much of Mercury’s rocky mantleContinuar Leyendo
The number of people who live past the age of 100 has been on the rise for decades, up to nearly half a million people worldwide. Washington, 04 de ulio de 2021.- There are, however, far fewer «supercentenarians,» people who live to age 110 or even longer. The oldest livingContinuar Leyendo
