Jan Bartek — AncientPages.com — Some already call it Australia’s lost Atlantis, but it is not quite the mythical underwater city Plato mentions. A large underwater site that was home to hundreds of thousands of people has been identified and mapped by scientists. Rising seas submerged the land northwest of Australia at the end of the last glacial period.

Using newly available high-resolution sonar data, the research team reconstructed the topography of the 400,000 square kilometers of land that is now covered by the Indian Ocean, known as the Northwest Shelf.

UK startup VividQ claims to have created the first-ever holograms with a “retina resolution.”

The milestone means holography can now match the resolution and real-life focus cues expected by the human eye, according to VividQ. The result is a “more natural viewing experience than ever before,” the company said. It now plans to deploy the tech in next-generation VR headsets.

To create the holograms, the company engineers light waves to render objects in 3D space. The technique mirrors the way we see objects because they reflect light into our eyes. In holography, software sets the light pathways.

Summary: Physical activity enhances the ability to learn and remember motor skills. The new research involved 67 young men and explored how exercise before and after motor skill learning impacts memory retention.

The study found that exercising both before and after learning optimizes memory formation, with a notable 10% improvement in remembering motor skills. This research is significant for various fields, from rehabilitation to skill training, demonstrating that incorporating physical activity can enhance learning effectiveness.

The engines driving the growth of the world’s highest mountains into the sky run deep beneath the planet’s skin. Geologists have some idea of the mechanisms at work, but evidence has so far left plenty of room for debate over the details.

Combined with a fresh look at previous research, a recent analysis of new seismic data collected from across southern Tibet has delivered a surprising depiction of the titanic forces operating below the Himalayas.

Presenting at the American Geophysical Union conference in San Francisco last December, researchers from institutions in the US and China described a disintegration of the Indian continental plate as it grinds along the basement of the Eurasian tectonic plate that sits atop it.

Summary: Researchers discovered that different layers of the brain’s cortex exhibit distinct electrical activity patterns, with rapid gamma waves in the upper layers and slower alpha and beta waves in the deeper layers. This pattern is consistent across various brain regions and species, including humans, suggesting a fundamental role in cortical function.

The research indicates that imbalances in these oscillations might be linked to neurological disorders like ADHD. This study not only deepens our understanding of brain function but also opens new possibilities for diagnosing and treating neuropsychiatric disorders.
