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…
Almost 20 million years ago, Switzerland was a part of an Island populated by fish, sharks, and dolphins, with mussels and sea urchins on the seabed. Paleontologists at the University of Zurich have investigated over 300 whale and dolphin fossils from this period. Strong currents pulled the animal skeletons across the ocean floor. They scattered…
Flirting involves various signals communicated between individuals to attract potential mates. Different flirtation tactics have been described. But, they are not always fruitful for everyone and in every situation. A new study by NTNU, Bucknell University in Pennsylvania, and the State University of New York at Oswego, found one of the best strategy to flirt.…
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…
A pulsar is a neutron star that rotates quickly and releases two polarised radio lights. The beams create a unique timing and polarisation signature as they burst across space. Since the first pulsar discovery, a lot of effort has been devoted to developing efficient and sensitive search algorithms. Traditional methods of finding pulsars look for…
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…
The black hole at the center of the Perseus galaxy cluster generates sound. This happens due to pressure waves emitted by black holes causing ripples in the cluster’s hot gas. However, humans cannot hear some 57 octaves below middle C. Thanks to NASA for bringing more notes to this black hole sound machine. NASA has…
In the second quantum revolution framework, single-photon emitters (SPEs) have emerged as an important building block for the implementation of fast-operating quantum devices. For such use, an ideal SPE should allow for the production of bright photon streams of high purity along with on-chip integration capabilities for industrial purposes. There have been promising candidates in…
UNSW scientists have announced a breakthrough in the field of renewable energy. They have developed a new kind of solar cells that can produce electricity even at night.’ Known as ‘Night-time’ solar power, the technology generates electricity from heat radiated as infrared light, in the same way as the Earth cools by radiating into space…
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.…
