In 2021, an investment firm bought 2,000 acres of real estate for about USD 4 million. Normally this would not make headlines, but in this case the land was virtual. It existed only in a metaverse platform called The Sandbox. By buying 792 non-fungible tokens on the Ethereum blockchain, the firm then owned the equivalent […]

Since the start of the war in Ukraine, the number of people studying Ukrainian on Duolingo, a language learning website and mobile app, has increased by more than 500%. Most of those who are taking up Ukrainian are probably unaware that there is a long-running controversy about this particular form of speech. One side views […]
Acute leukemia is characterized by the proliferation and accumulation of hematopoietic progenitor cells (which are able to differentiate to create specialized cell types) in the bone marrow that impede normal blood production. D epending on the cell population affected, it can be classified in Acute Lymphoblastic Leukemia (ALL) and Acute Myeloid Leukemia (AML). ALL starts […]
Could it be that even our hands show traces of having evolved for violence? The unique structure of human hands has been extolled as marvelously adapted for precise control and tool use. But they may also betray in their proportions and structure having been selected for killing. This, at least, is a hypothesis posed by […]

Pluto, the Solar System’s largest dwarf planet, just became even more interesting with a report that icy lava flows have recently covered substantial tracts of its surface. In this context, “recently” means probably no more than a billion years ago. That’s old, of course – and there is no suggestion that volcanoes are still active […]

While they may lack some of the melodic qualities of birds or whales, there are almost 1,000 species of fish that use sounds to communicate, and possibly many more. Yet, despite nearly 150 years of contemporary scientific research into fish sound production, there was no global inventory of fish species known to make sounds. Until […]
We live on a planet that is commonly known as the blue planet. This is because more than 70% of its surface is covered by water. However, it is ironic that one of the biggest problems humanity will face in the coming decades is the scarcity of drinking water. Despite the large amount of water […]
