Today, modern crabs, lobsters, shrimp and shrimp are sometimes called sea bugs, and as part of the arthropod family, which is characterized by strong armor and segmented joints, the name makes sense. …

[ad_1] For the first time, physicists have recorded sound waves moving through a perfect fluid with the lowest possible viscosity, as allowed by the laws of quantum mechanics, an ascending glissando of the frequencies at which the fluid resonates. This research can help us understand some of the most extreme …

[ad_1] Seeing what the hell is going on inside of us is useful for many aspects of modern medicine. But how to do this without cutting and cutting barriers such as flesh and bone to observe intact living tissue, such as our brains, is a difficult thing to do. Thick, …

[ad_1] Our brains are extraordinary pieces of biological machinery. Among the many difficult jobs they handle with apparent ease is that of distinguishing true words from random letter strings, all with great speed and precision. Now, scientists think they have found the part of the brain responsible for this task. …

[ad_1] In September 2019, my colleague Anna Kapinska gave a presentation showing interesting objects she had found while navigating our new radio astronomy data. He had begun to notice very strange shapes that he could not easily adapt to any known type of object. Among them, Anna labeled as WTF?, …

[ad_1] The universe is a mysterious place. We don’t know why it exists and there are many unanswered questions about how. But what if it was created, on purpose, by an intelligent entity? Is there any way to find out? In 2005, a pair of physicists proposed that if there …

[ad_1] COVID-19 may have already arrived in the United States in December 2019, before the disease was even identified in China, a new study suggests.

[ad_1] The famous Arecibo Observatory telescope in Puerto Rico, which once starred in a James Bond film, collapsed on Tuesday when its 900-tonne receiving platform plummeted 140 meters onto the radio dish below. Engineers had recently warned of the massive facility’s decayed condition, and the US National Science Foundation (NSF) …

[ad_1] Why and how our dreams are affected by our daily lives has long fascinated scientists, and a new study sheds light on how the spread of COVID-19 – and ongoing changes in our habits – is affecting what we dream. Anger and sadness have become more common in dreams …

[ad_1] Wherever you have fluid, you can also find vortex rings there. Now, scientists have found vortex rings somewhere fascinating – inside a tiny pillar made of a magnetic material, the gadolinium-cobalt intermetallic compound GdCo.2. If you’ve seen smoke rings or bubble rings underwater, you’ve seen vortex rings – donut-shaped …
