Scientists find traces of black holes from other universes in the night sky. This shows that there have been other universes.
New Scientist says that the idea is based on a thing called “conformal cyclic cosmology” (CCC). It means that our universe didn’t start with a single Big Bang. Instead, it goes through cycles of Big Bangs and shrinking.
Even though most of the universe would be destroyed from one cycle to the next, these scientists say that some electromagnetic radiation might make it through the process. Their research results have been posted on arXiv.
Scientists at the University of California, San Francisco (UCSF) and IBM Research have created a virtual library of thousands of “command sentences” for cells using machine learning. These “sentences” are based on combinations of “words” that direct engineered immune cells to find and continuously eliminate cancer cells.
This research, which was recently published in the journal Science, is the first time that advanced computational techniques have been applied to a field that has traditionally progressed through trial-and-error experimentation and the use of pre-existing molecules rather than synthetic ones to engineer cells.
The advance allows scientists to predict which elements – natural or synthesized – they should include in a cell to give it the precise behaviors required to respond effectively to complex diseases.
NASA scientists report the discovery of LHS 475 b, an exoplanet almost identical in size and mass to Earth, and the first to be confirmed by the James Webb Space Telescope.
LHS 475 is a red dwarf star with about a quarter of our Sun’s mass and radius, located relatively close in our stellar neighbourhood at 41 light years away. Astronomers have now confirmed that the system contains at least one known exoplanet, designated LHS 475 b.

As understandings of human intelligence evolve, so, too, do understandings of animal intelligence.
A recently discovered acoustic effect allows a hot gas to simulate the gravity-induced convection within a star or giant planet.
Sometimes a light bulb goes on—literally—and a scientific advance is made. Researchers studying an acoustic effect in high-powered light bulbs have developed a system that mimics the gravitational field around planets and stars [1]. The team demonstrated that sound waves in the bulb generate a force that pulls gas toward the bulb’s center. This gravity-like force causes the gas to move around in convection cycles that resemble fluid flows in the Sun and in giant planets. With further improvements, the system could be used to investigate convection behavior that is too difficult to simulate with computers.
In 2017, research on high-powered sulfur lamps revealed that sound waves could drive hot gas to ball up in the center of the bulbs [2]. The surprising phenomenon caught the attention of Seth Putterman’s acoustic group at the University of California, Los Angeles. The team studied the clumping and showed that it could be explained by the acoustic radiation force. This force is well known in acoustic levitation experiments, in which sound waves scattering off an object, such as a small bead, can exert a force (see Synopsis: Tossing and Turning). Putterman and his colleagues showed that, in the bulbs, this force acts not at the surface of an object where sound scatters, but throughout the gas, where density variations redirect the sound waves. “We knew that the force acts at a sharp interface between something solid and a gas,” says team member John Koulakis. “In the bulb, there’s no sharp interface—just variations—but there still is a force.”
