Non-alcoholic fatty liver disease (NAFLD) is the most prevalent hepatic pathology associated with the global obesity pandemic. NAFLD is the leading risk factor for non-alcoholic steatohepatitis (NASH) and liver cirrhosis. It is closely linked to the development of hepatocellular carcinoma. In addition, NAFLD is associated with increased mortality. An imbalance between energy intake and consumption…
A man is a social animal. He is always in search of and expansion of his social network. But many questions about ancient interactions remain, such as where and when ancient populations connect, what social exchanges took place and what mechanisms provoked their eventual isolation. Understanding when and how these groups are connected is critical…
Comets go through a colorful metamorphosis as they cross the sky. The green color is a good omen, and many comets display this color. The green color signifies that the comet is getting more active as it gets closer to the Sun. But strangely, this green shade disappears before it reaches the one or two…
Astrophysicists from the University of Miami, Yale University, and the European Space Agency have proposed a model for how the Universe came to be. Their model suggests that all the black holes were created immediately after Big Bang and account for all dark matter. Black holes have existed since the very beginning of the Universe.…
Teeth are among the most distinctive features of vertebrates, thanks to their exceptional diversity. Tooth complexity is strongly correlated to dietary habits, life history, or ecological adaptations across species. It also justifies why dental morphological characteristics such as shape and size are commonly used to identify patterns of vertebrate evolution. Researchers found the first animal…
Extreme warming at the end-Permian induced profound changes in marine biogeochemical cycling and animal habitability. These changes led to the largest metazoan extinction in Earth’s history. However, a causal mechanism for the extinction consistent with various proxy records of geochemical conditions through the interval has yet to be determined. Generally, scientists believe Siberian volcanos spitting…
The zebrafish (Danio rerio) is an important vertebrate model organism. One of the most readily observable phenotypes in the zebrafish is its distinctive pigmentation patterning, which, in wild-type adults, appears as alternating dark and light longitudinal stripes. Scientists at Berkeley Lab have developed a new technique to image every pigment cell of a whole zebrafish…
Using mathematical simulations, MIT researchers have shown that it would be possible to design a sensor, based on quantum physics, that could detect the SARS-CoV-2 virus. Courtesy of the researchers, edited by MIT News MIT scientists have developed a novel approach for detecting the presence of the SARS-CoV-2 virus. Based on quantum effects, the approach…
NASA‘s Juno spacecraft recorded sounds from a Ganymede flyby of the Jovian moon Ganymede on June 7, 2021. This 50 seconds soundtrack makes you feel like you were riding along as Juno sails past Ganymede. The soundtrack was obtained from data collected during the mission’s close flyby. The Waves instrument on Juno tunes in to…
A new study fills an important gap in scientists’ understanding of Schizophrenia. The study by Weill Cornell Medicine investigators suggests that multiple changes in brain cells during the first month of embryonic development may contribute to Schizophrenia later in life. Scientists used 3-dimensional “mini-brains” or organoids by using stem cells collected from patients with Schizophrenia…
