Memory, or the ability to store information in a readily accessible way, is an essential operation in computers and human brains. A key difference is that while brain information processing involves performing computations directly on stored data, computers shuttle data back and forth between a memory unit and a central processing unit (CPU). This inefficient separation (the von Neumann bottleneck) contributes to the rising energy cost of computers.

Approximately 4 billion years ago, Earth was in the process of creating conditions suitable for life. Origin-of-life scientists often wonder if the type of chemistry found on the early Earth was similar to what life requires today. They know that spherical collections of fats, called protocells, were the precursor to cells during this emergence of life. But how did simple protocells first arise and diversify to eventually lead to life on Earth?

Now, Scripps Research scientists have discovered one plausible pathway for how protocells may have first formed and chemically progressed to allow for a diversity of functions.

Dr. Shantanu Naidu: “When DART made impact, things got very interesting…the entire shape of the asteroid has changed, from a relatively symmetrical object to a ‘triaxial ellipsoid’ – something more like an oblong watermelon.”

On November 24, 2021, NASA launched the Double Asteroid Redirection Test (DART) mission with the goal of demonstrating that deflecting an incoming asteroid could prevent it from striking Earth by striking the asteroid itself. Just over nine months later, on September 26, 2022, this demonstration was successfully carried out as DART acted as a kinetic impactor and intentionally struck the Dimporphos asteroid, which measures 560 feet (170 meters) in diameter.

But while the impact successfully altered Dimorphos’ orbit around the binary near-Earth asteroid, Didymos, could it have altered other aspects of Dimorphos, as well? This is what a recent study published in The Planetary Science Journal hopes to address as a team of international researchers led by the NASA Jet Propulsion Laboratory (JPL) discovered the impact also altered the shape of Dimporphos.

GTC— NVIDIA today announced Project GR00T, a general-purpose foundation model for humanoid robots, designed to further its work driving breakthroughs in robotics and embodied AI.

As part of the initiative, the company also unveiled a new computer, Jetson Thor, for humanoid robots based on the NVIDIA Thor system-on-a-chip (SoC), as well as significant upgrades to the NVIDIA Isaac™ robotics platform, including generative AI foundation models and tools for simulation and AI workflow infrastructure.

“Building foundation models for general humanoid robots is one of the most exciting problems to solve in AI today,” said Jensen Huang, founder and CEO of NVIDIA. “The enabling technologies are coming together for leading roboticists around the world to take giant leaps towards artificial general robotics.”

These new medicines actually have a huge impact on the regulation systems of the body for weight loss which is activated by these new weight loss medicines which induce the production of glp1.

GLP-1 class medications reduce cardiovascular risk and treat diabetes. But they also allow people to lose an average of 10–20 percent of their body weight in the first year. What does that mean for the overweight or obese?

MONDAY, March 18, 2024 (HealthDay News) — In people with type 1 diabetes, fluctuations in blood sugar levels can affect thinking skills in various ways, new research shows.

Researchers looked specifically at what’s known as cognitive processing speed (how fast people process incoming information) and attention.

“Our results demonstrate that people can differ a lot from one another in how their brains are impacted by glucose,” said study co-senior author Laura Germine.
