Single photons are ideal carriers of quantum information, especially because they are fast, they barely interact with the environment or each other, and large-scale infrastructure for their distribution is already widely available. Now, before networks can really turn quantum, suitable quantum memories for single photons are needed. It is required for everything from buffering communication
The neutron’s lifetime is a significant parameter in Standard Model because it is used as an input for calculating the quark mixing matrix, which describes quark decay rates. If the quarks don’t mix as we expect them to, that hints at new physics beyond the Standard Model. To solve a long-standing puzzle about how long
Biodiversity was significantly reduced during the Permian-Triassic mass extinction, as may be seen especially in the body fossils of animals with complete skeletons. Both skeletonized and soft-bodied creatures can provide evidence to help us understand how entire ecosystems were impacted by the crisis and regenerated after it. In a new study, scientists from China, the
An asteroid originally discovered on 28 August 2021 by the Mount Lemmon Observatory was in a collision course with Earth. However, the latest observations by ESA’s asteroid team, working with experts at the European Southern Observatory, denied the claim. The 160-feet-wide (50 meters) asteroid named ‘2021 QM1’ has been officially removed from the risk list.
Hunga Tonga–Hunga Ha’apai is a submarine volcano in the South Pacific ocean. On 20 December 2021, an eruption began on Hunga Tonga–Hunga Ha’apai. About four weeks later, on 15 January 2022, the eruption reached a very large and powerful climax. A new study has confirmed that the eruption of the Hunga Tonga-Hunga Ha’apai submarine volcano
Whale sharks (Rhincodon typus) are found circumglobally in tropical, subtropical, and warm temperate waters. Their known seasonal aggregations and migratory movements are influenced by factors such as ocean currents, thermobiological systems, and productivity patterns. Several locations in the eastern tropical Pacific Ocean have known habitats for R. typus; Although it has long been known that
A supernova is the cataclysmic explosion of a star. A thermonuclear supernova explosion of a white dwarf is supposed to be the terminal event in the life of its progenitor star. These thermonuclear supernovae, known as Type Ia supernovae, are some of the most important tools in astronomers’ toolkits for measuring cosmic distances. For a
Depending on whether they spontaneously break discrete or continuous time translation symmetry, time crystals are categorized as discrete or continuous. While discrete time crystals have been investigated in detail in periodically driven systems, continuous-time crystals have yet to be experimentally realized. A new study by the Institute of Laser Physics at Universität Hamburg reported the
The analysis of spiral galaxy rotation curves has empirically highlighted since the late 1970s -a discrepancy between the amount of luminous matter and the mass budget required to explain the overall kinematic properties of such systems. The common belief traces back the missing mass to an unseen component called dark matter, constituted by cold (i.e.
Growing global food demand is currently facing a major constraint of efficient energy conversion using photosynthesis. Photosynthesis has evolved in plants for millions of years to turn water, carbon dioxide, and the energy from sunlight into plant biomass and the foods we eat. Most crop plants can convert sunlight and CO2 into plant biomass at
