New Phospholipid Discovery Rewrites the Story of the Origin of Life

Posted by in categories: chemistry, evolution

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.

DART Impact: Reshaping Dimorphos and Redefining Asteroid Dynamics

Posted by in categories: asteroid/comet impacts, existential risks

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.

NVIDIA Announces Project GR00T Foundation Model for Humanoid Robots and Major Isaac Robotics Platform Update

Posted by in categories: innovation, robotics/AI

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.”

How Ozempic, other weight-loss drugs are “changing medicine”

Posted by in category: biotech/medical

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?

How Blood Sugar Changes Affect Thinking in Folks With Type 1 Diabetes

Posted by in categories: biotech/medical, neuroscience

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.

Immunotherapy or allergy shots is based on a century-old concept that the immune system can be desensitized to allergens that trigger symptoms

Posted by in categories: biotech/medical, health

Allergy shots can potentially lead to lasting remission of allergy symptoms, and it may play a preventive role in the development of asthma and new allergies.


Immunotherapy treatment (allergy shots) is based on a century-old concept that the immune system can be desensitized to specific allergens that trigger allergy symptoms. These symptoms may be caused by allergic respiratory conditions such as allergic rhinitis (hay fever) and asthma.

While common allergy medications often control symptoms; if you stop taking the medication(s), your allergy symptoms return shortly afterward. Allergy shots can potentially lead to lasting remission of allergy symptoms, and it may play a preventive role in terms of development of asthma and new allergies.
