A research team has succeeded in implementing a distributed quantum sensor that can measure multiple spatially distributed physical quantities with high precision beyond the standard quantum limit with few resources. Their findings are published in the journal Nature Communications.

Sharing the exact time between distant locations is becoming increasingly important in all areas of our lives, including finance, telecommunications, security, and other fields that require improved accuracy and precision in sending and receiving data.

Quantum phenomena such as superposition and entanglement can be used to more precisely measure the time of different clocks in two distant spaces. Similarly, if you have two physical quantities, one in Seoul and one in Busan, you can share the entanglement state in Seoul and Busan and then measure the two physical quantities simultaneously with greater precision than if you measure the physical quantities in Seoul and Busan separately.

People often form strong emotional attachments with their companion animals.

Pet owners forced to be separated from their animals in crisis situations, including those who are victims of domestic violence, are suffering from a lack of support services needed to protect them.

These are the findings of a new review of 27 years of international research, published in the journal Anthrozoös, which unveils the increased risks to both safety and psychological well-being when people are faced with the threat of forced separation from their pets.

Elon Musk references a “revolutionary” late 2025 production start for EV brand’s new low-cost small car and SUV

Tesla CEO Elon Musk has outlined a 2025 production start for the all-electric car-maker’s upcoming “next-generation low-cost vehicle”, and confirmed the new model will initially be produced at Giga Texas before being outsourced to other plants around the world.

Musk made the announcement overnight during an investor’s earnings call and said the manufacturing processes set to be employed for Tesla’s new entry-level model/s will be revolutionary and head and shoulders above any other vehicle production on the planet.

Scientists and engineers have been pushing for the past decade to leverage an elusive ferroelectric material called hafnium oxide, or hafnia, to usher in the next generation of computing memory. A team of researchers including the University of Rochester’s Sobhit Singh published a study in the Proceedings of the National Academy of Sciences outlining progress toward making bulk ferroelectric and antiferroelectric hafnia available for use in a variety of applications.

In a specific crystal phase, hafnia exhibits ferroelectric properties —that is, electric polarization that can be changed in one direction or another by applying an external electric field. This feature can be harnessed in data storage technology. When used in computing, ferroelectric memory has the benefit of non-volatility, meaning it retains its values even when powered off, one of several advantages over most types of memory used today.

“Hafnia is a very exciting material because of its practical applications in computer technology, especially for data storage,” says Singh, an assistant professor in the Department of Mechanical Engineering. “Currently, to store data we use magnetic forms of memory that are slow, require a lot of energy to operate, and are not very efficient. Ferroelectric forms of memory are robust, ultra-fast, cheaper to produce, and more energy-efficient.”

Created by Robotiz3d and the University of Liverpool, this autonomous road maintenance robot is stepping out of the lab for its debut journey.

For humans, the chance of giving birth to multiples is less than 2%. The situation is different with stars, especially with particularly heavy stars. Astronomers observe stars that are many times heavier than the sun in more than 80% of cases in double or multiple systems. The key question is whether they were also born as multiples, or whether stars are born alone and approach each other over time.

Multiple births have long been the norm for massive stars. At least on the computer, because in theoretical simulations huge clouds of gas and dust tend to collapse and form multiple systems of massive stars. These simulations depict a hierarchical process in which larger cloud portions contract to form denser cores, and where smaller regions within those “parent cores” collapse to form the separate stars: massive stars, but also numerous less massive stars.

And astronomers do indeed find a wealth of fully formed multiple star systems, especially stars that weigh many times more than the sun. However, this does not yet prove that multiple systems with massive stars are already forming in the primordial cloud, as predicted by simulations.

Researchers at the Leibniz Institute for Immunotherapy (LIT) have demonstrated that killer T cells of the immune system not only eliminate pathologically altered cells, but also promote the subsequent tissue wound healing process.
