Rats love to dance đș:3
The team had two alternate hypotheses: The first was that the optimal music tempo for beat synchronicity would be determined by the time constant of the body. This is different between species and much faster for small animals compared to humans (think of how quickly a rat can scuttle). The second was that the optimal tempo would instead be determined by the time constant of the brain, which is surprisingly similar across species.
âAfter conducting our research with 20 human participants and 10 rats, our results suggest that the optimal tempo for beat synchronization depends on the time constant in the brain,â said Takahashi. âThis demonstrates that the animal brain can be useful in elucidating the perceptual mechanisms of music.â
Two different groups have tested a seemingly counter-intuitive property of the quantum world: That itâs possible to put a photon, a particle of light, in a superposition of states going forward and backward in time. This is not time travel and wonât lead to communicating with the past â but it is an intriguing demonstration of how time can be thought to work at a quantum level.
Unless you have a TARDIS or a DeLorean, time only flows in one direction (forward) for us. This annoying little fact that protects us from all sorts of paradoxes is called the arrow of time. It is believed to be related to the concept of entropy (which always increases in an isolated system like the universe) but it doesnât seem to be as fundamental at the quantum level.
Instead, something that appears to be fundamental is the so-called CPT symmetry (charge, parity, and time reversal symmetry). This holds for all physical phenomena, and if a combination of two of them is violated (such as famously the CP violations) there ought to be a violation in time symmetry as well.
The three to four-bedroom homes will be in a master-planned community in Georgetown, Texas. The units will be open for reservations in 2023.
Early on Thursday morning, Hurricane Nicole made landfall near Vero Beach on Floridaâs eastern coast. Because Nicole had a very large eye, nearly 60 miles in diameter, its strongest winds were located well to the north of this landfalling position.
As a result of this, Kennedy Space Center took some of the most intense wind gusts from Nicole late on Wednesday night and Thursday morning. While such winds from a Category 1 hurricane are unlikely to damage facilities, they are of concern because the space agency left its Artemis I missionâconsisting of the Space Launch System rocket and Orion spacecraftâexposed on a pad at Launch Complex-39B. The pad is a stoneâs throw from the Atlantic Ocean.
How intense were the winds? The National Weather Service hosts data from NASA sensors attached to this launch padâs three lighting towers on a public website. It can be a little difficult to interpret the readings because there are sensors at altitudes varying from 132 feet to 457 feet. Most of the publicly available data appears to come from an altitude of about 230 feet, however, which would represent the area of the Space Launch System rocket where the core stage is attached to the upper stage. The entire stack reaches a height of about 370 feet above the ground.

Commercial Holograms may soon get into the hand of regular consumers with the help of the biggest Hologram company called Lightfield. Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating three-dimensional images, but it also has a wide range of other applications. In principle, it is possible to make a hologram for any type of a light field.

In this bonus interview for the series Science Uprising, computer scientist and AI expert Selmer Bringsjord provides a wide-ranging discussion of artificial intelligence (AI) and its capabilities. Bringsjord addresses three features humans possess that AI machines wonât be able to duplicate in his view: consciousness, cognition, and genuine creativity.
Selmer Bringsjord is a Professor of Cognitive Science and Computer Science at Rensselaer Polytechnic Institute and Director of the Rensselaer AI and Reasoning Laboratory. He and his colleagues have developed the âLovelace Testâ to evaluate whether machine intelligence has resulted in mind or consciousness.

A team of researchers at the Korea Advanced Institute of Science and Technology, working with a colleague from Institute for Basic Science, both in the Republic of Korea, has found an easy way to create an electronic network inside a polymer. They used an acoustic field to connect liquid metal dots.
In their paper published in the journal Science, the group describes their technique and its possible uses. Ruirui Qiao and Shi-Yang Tang with the University of Queensland in Australia and the University of Birmingham, in the U.K., respectively, have published a Perspectives piece in the same journal outlining the work done by the team.
