50 years ago, Apollo astronauts brought samples of the lunar surface material, known as regolith, back to Earth. Now, 50 years later, scientists successfully used three samples to grow plants. This is the first time they have successfully grown the plant in the nutrient-poor lunar regolith. This breakthrough discovery- made by scientists at the University…
Quantum information systems derive their power from controllable interactions that generate quantum entanglement. Buiding scalable quantum information systems require programmable operations between desired qubits within a quantum processor. In most advanced approaches, qubits interact locally, constrained by the connectivity associated with their fixed spatial layout. In a new study, scientists demonstrated a quantum processor in…
The electronics industry for computers grows hand-in-hand with the decrease in the size of integrated circuits. Despite being essential to increase computational power, miniaturization becomes challenging. A possible alternative to this is using magnetism, which can keep the development of both cheaper and more powerful computers. A new discovery is not a direct recipe for…
In 2017 using Gaia-ESO Survey, astronomers detected a rare double-binary star system HD74438 in the Vela constellation. Further observation of this quadruple star system tracked the orbits of the stars. The observations revealed that this stellar quadruple comprises four gravitationally bound stars. In this system, a short-period binary orbits another short-period binary on a longer…
When we have something, the essential nutrients and other valuable components within the food are metabolized and find their way to cells throughout the body. When the metabolites reach the cell, they are completely broken down and segregated from one another so that each can play a role in specific functions that the mitochondria perform.…
To perform its function correctly, cells go through a lifecycle. This lifecycle includes growing to the right size. It is a vital process as it ensures the perpetuation of the cell population and the greater structure they are a part of. Checkpoints govern the cell cycle, preventing errors like mutations or DNA damage from being…
NASA’s Hubble Space Telescope has recently shared a dazzling view of a broad-brimmed Mexican hat resembling a galaxy called NGC 7814. Also known as ‘Little Sombrero’ or Caldwell 43, the galaxy is located 28 million light-years away. The ‘Little Sombrero’ is 80,000 light-years-wide and billions of years old. It features a bright central bulge, a…
Analysis of the star HD 222925 by the University of Michigan astronomer Ian Roederer revealed 65 elements. It comprises 42 heavy elements, including those detected in the rapid neutron capture process. The rapid neutron capture process or r-process starts with the presence of lighter elements such as iron. Then instantly, within just a second, neutrons…
40 Eri B is the second brightest white dwarf and among the first to be discovered in 1783. White dwarfs were once normal stars similar to the Sun but collapsed after exhausting all their fuel. Since the discovery of the first white dwarf, astronomers have tried to gain more insights into white dwarfs to get…
Today, at simultaneous press conferences worldwide, including at the European Southern Observatory (ESO) headquarters in Germany, astronomers unveiled the first image of the supermassive black hole at the center of our Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of…
