In 2018, Groh’s team discovered that the ears make a subtle, imperceptible noise when the eyes move. In a new report appearing the week of November 20 in the journal Proceedings of the National Academy of Sciences, the Duke team now shows that these sounds can reveal where your eyes are looking.
It also works the other way around. Just by knowing where someone is looking, Groh and her team were able to predict what the waveform of the subtle ear sound would look like.
These sounds, Groh believes, may be caused when eye movements stimulate the brain to contract either middle ear muscles, which typically help dampen loud sounds, or the hair cells that help amplify quiet sounds.
In a recent study published in Nature Communications, researchers aimed to develop a model of rumination, a mental process characterized by persistent negative self-reflective thoughts that can lead to depression and anxiety. Using resting-state functional magnetic resonance imaging (rsfMRI) — a technique that captures brain activity when a person is at rest — they identified a specific region of the brain, the dorsal medial prefrontal cortex (dmPFC), as playing a pivotal role in these ruminative thoughts.
Recognizing that rumination can be an early risk factor for depression, the researchers aimed to develop methods for subclinical detection and intervention before clinical episodes of depression occur. Early detection and intervention can be crucial for preventing the development of more severe mental health conditions.
The default mode network (DMN), a large-scale resting-state network, had been consistently linked to rumination in previous research. But the precise brain regions responsible for variations in individual levels of rumination have remained elusive. The researchers wanted to investigate the specific role of the DMN and its subsystems in rumination, as it is involved in various processes related to self-referential thought, autobiographical memory, emotional experience, and more.
How are we so smart? We seem to be able to make process data with ease, doing tasks in seconds that take supercomputers much longer. Well, one thought is that we fundamentally take advantage of quantum mechanics to perform calculations similar to a quantum computer. This would give us a biologically produced quantum speed up in our brains. Until recently this was just a thought, there is no evidence that this is true. Well, now scientists believe that they may have found evidence of quantum interaction in our brains. Even more importantly, they showed that these quantum interactions are related to our consciousness. In this video, I discuss these latest results.
Meet the fast-legged TITA robot, which made its first appearance at the ICRA 2023 Robotics Show. Easily switching between wheeled and walking modes, the robot with eight degrees of freedom is able to move quickly on any terrain. In addition, the developers report that TITA combines exceptional perceptual abilities with advanced decision-making capabilities. Its maneuverability, sleek design, modular construction and ability to quickly swap payloads and accessories make it a true Swiss knife in the world of security and service robots. TITA also has exceptional fall resistance, improved self-healing capabilities, instant response time and enhanced obstacle avoidance ability. The robot easily adapts to difficult terrain and, importantly, supports secondary development in multiple modes. The latter not only allows you to control it at any level using RPC, but also allows you to program the robot for your tasks. If TITA has captured your heart as well as ours, you can learn more about the robot and even buy it for yourself by using the QR code on the screen.

In his new video, Colonel Markus Reisner explains how both Russia and Ukraine are trying to use propaganda to influence the minds of western populations. He shows that in addition to the traditional domains of war, the cyber domain and the information domain are playing an increasingly important role today.

A groundbreaking paper in Nature Neuroscience seems straight out of a sci-fi movie.
We are now able to translate human thought into text and images with the help of artificial intelligence. Is this the end of privacy? Here’s everything you need to know.
A single-celled organism with no brain or nervous system to speak of may still form memories and pass those memories on to future generations, according to new research.
The ubiquitous bacterium, Escherichia coli, is one of the most well-studied life forms on Earth, and yet scientists are still discovering unexpected ways that it survives and spreads.
Researchers at the University of Texas and the University of Delaware have now uncovered a potential memory system that allows E. coli to ‘remember’ past experiences for several hours and generations thereafter.
