A gravitational lens is any object that deflects light by gravitation as described by the general theory of relativity; it is analogous to a lens in optics. The prediction of a gravitational lensing effect was confirmed repeatedly in observations on quasars. In 1979 an apparently double quasar was discovered, due to the multiple image of […]
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 […]
As we saw in the first entry of this series, traditionally the idea of theoreticity had been understood as a kind of ‘negative’ concept, for theoretical entities or properties were thought about as those that cannot be observed; hence, ‘theoretical’ was more or less a synonym of ‘ un -observable’. Things started to change around […]
Massive protoplanet formed in unexpected way A protoplanet with a mass many times larger than Jupiter’s likely formed as the result of a massive implosion, pulling together gas and dust. Based on the planet’s size and distance from the nearest star, astronomers found that planet AB Aur b didn’t form as they originally thought, but […]
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 […]
Scientists find galaxy far, far away Astronomers discovered HD1, an extremely energetic galaxy candidate that is 13.1 billion light-years from Earth, making it 100 million light-years farther away than what is currently the most distant galaxy. According to research, the energy emitted from HD1 could be because it is a gigantic black hole or contains […]
When talking about molecules, “open shell” signifies that there are unpaired electrons. In terms of molecular orbital theory, it means that some molecular orbitals are singly occupied. Organic open-shell compounds are extraordinarily attractive materials for their use in molecular spintronics. In spintronics, new memory and logic devices are being developed based on the use of […]
The UN’s new IPCC report on the mitigation of climate change says that immediate and deep emissions reductions are needed to limit global warming, along with removing carbon dioxide back out of the air in future. Meanwhile, the world’s governments are urging fossil fuel companies to drill for more oil and gas as fast as […]
Imagine a Universe that started with a huge explosion setting the beginning of space and time to the point that such concepts have no meaning until then. Imagine a Universe that, after an inflationary phase (extremely fast expansion), kept expanding and forming stars and galaxies distributed in a sponge-like structure dominated by walls and filaments […]
