It’s easy to overlook blatant, glaring aspects to our surroundings when we’re hyper focused on a task. These neuroscience theories explain why.
Over the past decade, scientists have made tremendous progress in generating quantum phenomena in mechanical systems. What seemed impossible only fifteen years ago has now become a reality, as researchers successfully create quantum states in macroscopic mechanical objects.
By coupling these mechanical oscillators to light photons—known as “optomechanical systems”—scientists have been able to cool them down to their lowest energy level close to the quantum limit, “squeeze them” to reduce their vibrations even further, and entangle them with each other. These advancements have opened up new opportunities in quantum sensing, compact storage in quantum computing, fundamental tests of quantum gravity, and even in the search for dark matter.
In order to efficiently operate optomechanical systems in the quantum regime, scientists face a dilemma. On one hand, the mechanical oscillators must be properly isolated from their environment to minimize energy loss; on the other hand, they must be well-coupled to other physical systems such as electromagnetic resonators to control them.

The public’s anxiety over new AI technology is misguided, according to theoretical physicist Michio Kaku.
In an interview with CNN’s Fareed Zakaria on Sunday, the futurologist said chatbots like OpenAI’s ChatGPT will benefit society and increase productivity. But fear has driven people to largely focus on the negative implications of the programs, which he terms “glorified tape recorders.”
“It takes snippets of what’s on the web created by a human, splices them together and passes it off as if it created these things,” he said. “And people are saying, ‘Oh my God, it’s a human, it’s humanlike.’”

Jonathan the tortoise became the oldest tortoise in human record in 2022, being granted the accolade by the Guinness World Records (who recently named the world’s oldest cat) after turning 190. It’s been accepted that he hatched in 1,832 based on photographic records, but it wasn’t until November of this year that he was finally granted an official birthday.
Jonathan’s birthday was declared to be December 4, 1832, by the governor of the British overseas territory Nigel Phillips, Guardian reports. It was celebrated with a three-day party at his home on the island of St Helena in the South Atlantic Ocean and damn, that’s a party we wish we’d got an invite to.
Reptilian pals and local residents were invited to the soiree that was held at the governor’s house complete with a tortoise-friendly birthday cake. A fitting tribute to a creature that’s both the world’s oldest living animal, and the oldest tortoise on human record.
The Greenland shark is the poster child for animals with extreme longevity – and with good reason. As the longest-living vertebrates on Earth, they develop incredibly slowly in their frosty Arctic home, but when it comes to the longest-living animals on Earth, they’re not all that.
The ocean quahog is a pretty unremarkable-looking clam, reaching around 5 centimeters (2 inches) in size, and yet it can take them over 200 years to get there. The oldest on record was 507 years old, topping the Greenland shark, and yet it still only makes it the oldest known non-colonial animal.
“Animals living longer than 500 years?!” I hear you cry? Yes siree Bob. Let’s take a look at some of Earth’s oldest animals.
The iconic movie Alien once claimed: “In space, no one can hear you scream.” However, physicists Zhuoran Geng and Ilari Maasilta from the Nanoscience Center at the University of Jyväskylä, Finland, beg to differ. Their recent research suggests that under specific conditions, sound can indeed be transmitted powerfully across a vacuum.
Their findings, published recently in the journal Communications Physics, reveal that in certain scenarios, sound waves can “tunnel” through a vacuum gap between two solid objects, provided those objects are piezoelectric. These particular materials generate an electrical response when subjected to sound waves or vibrations. Given that an electric field can be present in a vacuum, it can effectively carry these sound waves across.
The requirement is that the size of the gap is smaller than the wavelength of the sound wave. This effect works not only in the audio range of frequencies (Hz-kHz), but also in ultrasound (MHz) and hypersound (GHz) frequencies, as long as the vacuum gap is made smaller as the frequencies increase.
Russian experts monitoring their moon-bound unmanned spacecraft Luna-25 have switched on its scientific equipment and started processing the first data.
Russia is aiming to become the first country to carry out a soft landing on the lunar south pole — a region thought to hold pockets of water ice.
Space agency Roscosmos said in a statement on Sunday: Luna-25 continues its flight to the Earth’s natural satellite — all systems of the automatic station are working properly, communication with it is stable, the energy balance is positive.
