New research published by scientists at Kessler Foundation provides critical insights into the role of sleep in motor learning for individuals recovering from traumatic brain injury (TBI). The study sheds light on how sleep, specifically a short nap, influences brain activity associated with motor skill improvement, with implications for optimizing rehabilitation strategies.

The article, “Neural mechanisms associated with sleep-dependent enhancement of motor learning after brain injury”, was published in the Journal of Sleep Research. The study was led by Kessler Foundation researchers Anthony H. Lequerica, Ph.D., with additional authors Tien T. Tong, Ph.D., Paige Rusnock, Kai Sucich, Nancy Chiaravalloti, Ph.D., Ekaterina Dobryakova, Ph.D., and Matthew R. Ebben, Ph.D., and Patrick Chau, from Weill Cornell Medicine, New York.

The study involved 32 individuals with TBI, randomly assigned to either a sleep or wake group following training on a motor task. The sleep group had a 45-minute nap, while the wake group remained awake, watching a documentary.

Nestled at the back of your head, the cerebellum is a brain structure that plays a pivotal role in how we learn, adapting our actions based on past experiences. Yet the precise ways in which this learning happens are still being defined.

A study led by a team at the Champalimaud Foundation brings new clarity to this debate, with a serendipitous finding of so-called “zombie neurons.” These neurons, alive but functionally altered, have helped to advance our understanding of the cerebellum’s critical teaching signals.

The word “cerebellum” means “little brain,” despite the fact that it holds more than half the brain’s neurons. It is essential for coordinating movements and balance, helping you perform everyday tasks smoothly, like walking down a crowded street, or playing sports. It is also crucial for the learning process that allows you to associate sensory cues with specific actions.

The plan includes seven major recommendations.

The first is creating a new state authority to oversee nuclear development. They’ll also establish a single point of contact to help companies navigate the complex permitting process.

Education is also a big focus of the plan. It calls for partnerships with community colleges and universities to train workers for these high-tech jobs.

Natural forms of opiates and dopamine — key players in brain pathways that diminish pain and enhance reward — seem to be telltale ingredients of the elevated tails in our anticipation training program. Observing tail posture in rats adds a new layer to our understanding of rat emotional expression, reminding us that emotions are expressed throughout the entire body.

While we can’t directly ask rats whether they like to drive, we devised a behavioral test to assess their motivation to drive. This time, instead of only giving rats the option of driving to the Froot Loop Tree, they could also make a shorter journey on foot — or paw, in this case.

VMware has announced that its VMware Fusion and VMware Workstation desktop hypervisors are now free to everyone for commercial, educational, and personal use.

In May, the company also made VMware Workstation Pro and Fusion Pro free for personal use, allowing students and home users to set up virtualized test labs and experiment with other OSs by running virtual machines and Kubernetes clusters on Windows, Linux, and macOS devices.

Starting this week, the Pro versions and the two products will no longer be available under a paid subscription model.

Researchers from the University of Montpellier, the University of Zurich, Naturhistorisches Museum Bern, and other institutions have found that breed function and behavior correlate with relative endocranial volume (REV) in domestic dogs.

Domestic dogs exhibit variations of morphologies and cognitive abilities, a diversity rooted in centuries of domestication and selective breeding for functional attributes. Historically, mammals have shown a trend toward larger brains to support advanced cognition, a pattern that appears disrupted in domestic dogs.

Despite having, on average, 20% smaller brains relative to their wild ancestral counterpart, the gray wolf, domestic dogs often demonstrate a range of equivalent cognitive skills, challenging some conventional assumptions about brain size and intelligence.

From education to work and leisure, internet access is essential to modern life. Yet, since the first days of the world wide web, this access has been unequal. The US, France and the UK gained a headstart in the 1990s and developing countries have been seeking to catch up ever since.

One region where this process is now complete is the Arabian Peninsula. From relative obscurity in connectivity rankings three decades ago, countries such as the United Arab Emirates (UAE) and Qatar have leapfrogged their Western peers. Look at measures of internet speeds, in fact, and the UAE now leads the world.¹ Having delivered internet access at home, e& (etisalat and), the telecommunications giant and leading global technology group headquartered in the UAE, hopes to expand connectivity worldwide.

Following a signing ceremony Wednesday in Denmark’s capital city, Copenhagen, NASA embraced Denmark as the 48th nation to commit to the safe and responsible exploration of space that benefits humanity.

“We welcome Denmark’s signing of the Artemis Accords today,” said NASA Administrator Bill Nelson. “Denmark, as a founding member of the European Space Agency (ESA), has contributed to space exploration for decades, including collaborating with NASA on Mars exploration. Denmark’s signing of the Artemis Accords will further international cooperation and the peaceful exploration of space.”

Christina Egelund, minister of higher education and science, signed the Artemis Accords on behalf of Denmark. Alan Leventhal, U.S. ambassador to the Kingdom of Denmark also participated in the ceremony, and Nelson contributed recorded remarks.

YouTube videos on autism primarily provide educational content with balanced perspectives, reducing stigmatization, though viewer comments often remain negative. This highlights YouTube’s dual role in improving understanding while revealing persistent public misconceptions.
