Another glorious year in the scientific community is coming to an end. In this year, astronomers have made new discoveries about the universe, biologists have created clearer maps of Earth’s life, and paleontologists have added richer details to the dinosaurs that ruled the Earth millions of years ago. The latest achievements in human scientific research constantly attract us and reveal new mysteries waiting to be explored.
Astronomers have detected huge temporal and spatial ripples
This is the first time scientists have detected low-frequency gravitational waves passing through the Milky Way. These cosmic ripples may be distant echoes transmitted by the interaction and fusion of supermassive black holes billions of light-years away. An international consortium of researchers discovered these cosmic waves by measuring subtle temporal variations in the radio signals emitted by pulsars. The research results indicate that there were far more giant black holes in the early universe than previously imagined; Continuing to study these new types of gravitational waves will help uncover more information about the origin of the universe and better explain the dark matter and invisible forces that drive cosmic motion.
2. Brain Decoder Translates People’s Thoughts – Creating Hope for Aphasic People
Researchers at the University of Texas at Austin have reported revolutionary progress in a new system based on artificial intelligence technology – a system that can translate human brain activity into a continuous stream of text in the laboratory. Strictly speaking, this is not a “mind reading” device. This semantic decoder does not require surgical implantation; It relies on functional magnetic resonance imaging to capture the brain activity of subjects when responding to content such as broadcasts or images. The brain decoding system does not provide literal translation texts. Essentially, it compiles a dictionary of brain activity patterns based on an individual’s response to specific words or images; When observing the brain activity of subjects when facing other things, this dictionary can provide a reference for inferring the thoughts of the subjects. This technology is based on AI language generation algorithms and is currently in the early stages of development, but it has raised thorny issues in terms of mental privacy and ethics in involuntary contexts. However, for the families of patients with communication barriers, it has raised new hope.
