Albert Einstein taught us that space and time belong together to a common entity: space-time. This means that time becomes a dimension, similar to space, and has profound consequences for the nature of time. Most importantly it leads to what has been called the block universe, a universe in which all moments of time exist the same way together. The future, the present, and the past are the same, it is just our perception that suggests otherwise.

The axolotl (Ambystoma mexicanum) is an aquatic salamander renowned for its ability to regenerate its spinal cord, heart and limbs. These amphibians also readily make new neurons throughout their lives. In 1964, researchers observed that adult axolotls could regenerate parts of their brains, even if a large section was completely removed. But one study found that axolotl brain regeneration has a limited ability to rebuild original tissue structure.

So how perfectly can ’s regenerate their brains after injury?

As a researcher studying regeneration at the cellular level, I and my colleagues in the Treutlein Lab at ETH Zurich and the Tanaka Lab at the Institute of Molecular Pathology in Vienna wondered whether axolotls are able to regenerate all the different in their brain, including the connections linking one brain region to another. In our recently published study, we created an atlas of the cells that make up a part of the axolotl brain, shedding light on both the way it regenerates and brain evolution across species.

Summary: Axolotls have the ability to regenerate brain areas following an injury. Researchers have mapped cell types and genes associated with neurodegeneration in the axolotl brain, discovering some similarities in the human brain. The findings could pave the way for new neurodegenerative therapies.

One of the greatest challenges in the field of neurology and intensive care medicine is correctly diagnosing the level of consciousness of a patient in coma due to severe brain injury. Scientists of the Human Brain Project (HBP) now have explored new techniques that may pave the way to better tell apart two different neurological conditions.

Their findings, published in the journal eLife, reveal important information on the mechanisms of disorders of consciousness.

The team of researchers from University of LiĂšge, GIGA Consciousness Research Unit and Coma Science Group and CHU de LiĂšge (Belgium), Universitat Pompeu Fabra (Spain), Vrije Universiteit Amsterdam (Netherlands), and others, assessed brain functional network states as a marker of consciousness to potentially distinguish patients in the unresponsive wakefulness syndrome (UWS) and minimally conscious state (MCS).

AUSTIN (KXAN) — Walking around Austin, you may see something surprising — self-driving cars rolling around the roads.

Earlier this year, autonomous vehicle technology company Argo AI launched its driverless operation in Austin. Argo AI public policy and government relations manager Sly Majid said these cars are key to the future of transport.

“Autonomous vehicle technology is incredible,” he said. “The vehicle is doing the dynamic driving tasks; the vehicle is the driver of the car.”

What can we learn from history, the age of exploration?

How will the new age of space exploration will change our future, and what can we learn from history?

A new age of explorations that is forming before our eyes, which may change the trajectory of our civilization.

Starting Monday, drive-thru customers at two Panera Bread locations in upstate New York will have their orders taken by a computer in a test of artificial intelligence technology’s accuracy and ability to decrease service times.

The sandwich chain is the latest restaurant company to invest in potential improvements to the drive-thru experience. A surge in drive-thru ordering during the Covid pandemic led to long lines of cars wrapped around restaurants, pushing chains to focus on speed of service and order accuracy.

For example, McDonald’s has also been working to automate its drive-thru lane, announcing a partnership last year with IBM to work toward that goal. Yum Brands’ Taco Bell and Restaurant Brands International’s Burger King have been building double drive-thru lanes at some locations to allow customers to pick up their digital orders more quickly. Fast-casual chains like Shake Shack and Sweetgreen that once balked at drive-thru lanes have been adding them.
