Artificial intelligence researchers claim to have made the world’s first genuine scientific discovery using a large language model (LLM), which is behind ChatGPT and similar programs. This signals a major breakthrough.

The discovery was made by Google DeepMind, an AI research laboratory where scientists are investigating whether LLMs can do more than just repackage information learned in training and actually generate new insights.

It turns out that they can, and the implications are potentially huge. DeepMind said in a blog post that its FunSearch, a method to search for new solutions in mathematics and computer science, made “the first discoveries in open problems in mathematical sciences using LLMs.”

ABSTRACT: Optogenetics has been widely expanded to enhance or suppress neuronal activity and it has been recently applied to glial cells. Here, we will discuss about a novel approach based on selective expression of melanopsin, a G-protein-coupled photopigment, in astrocytes. We will show the selective expression of melanopsin in astrocytes allows triggering astrocytic Ca2+ signalling, but also studying astrocyte–neuron networks and the behavioral astrocytic contribution.\

Chair and introduction: Dr. Letizia Mariotti (CNR — Institute of Neuroscience)

Scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) have discovered a new plasma instability that promises to revolutionize our understanding of the origin of cosmic rays and their dynamic impact on galaxies.

At the beginning of the last century, Victor Hess discovered a new phenomenon called cosmic rays that later on earned him the Nobel prize. He conducted high-altitude balloon flights to find that the Earth’s atmosphere is not ionized by the radioactivity of the ground. Instead, he confirmed that the origin of ionization was extra-terrestrial. Subsequently, it was determined that cosmic “rays” consist of charged particles from outer space flying close to the speed of light rather than radiation. However, the name “cosmic rays” outlasted these findings.

Recent advances in cosmic ray research.

Tesla has unveiled Gen 2 of it’s Optimus Robot… and WOW, the progress in the past year has been incredible. Tesla is well on their way to commercializing a humanoid robot later this decade. This represents the biggest change in Tesla’s addressable market ever, as the potential sales from a humanoid robot to replace manual labor could be $25T. For long-term Tesla investors this is a must watch project. People thought Elon Musk was crazy when he told the world about this AI project… but it’s getting closer to reality by the day. What do you think? Are you going to buy an Optimus robot? Why?

Dr Robert Sapolsky is a Professor at Stanford University, a world-leading researcher, and an author. Stress is an inevitable part of human life. But what is stress actually doing to the human body when it happens for such a prolonged period of time? And what does science say are the best interventions to defeat it? Expect to learn the crucial difference between short term and long term stress, how stress actually impacts the human system, the neurodevelopmental consequences of stress and poverty, how to detrain your dopamine sensitivity, what everyone doesn’t understand about how hormones work, whether believing in free will is a useful world view, why there is a relationship between belief in free will and obesity and much more…

Targeted drugs aim to pinpoint the exact location in the body where diseased tissue is located and where the medicine is required. The manifold benefits of administering a targeted drug include heightened efficacy, as the drug is meticulously designed for specificity, thereby reducing side effects, and minimizing damage to healthy tissue. Consequently, this approach enhances the patient’s quality of life during treatment.

Oligonucleotides (ONs), specifically designed short chains of DNA or RNA, have emerged as a crucial tool with immense potential in personalized medicine. These therapeutic ONs are already in use for conditions, such as certain types of muscular dystrophy and , which conventional drugs cannot address.

Depending on the type, ONs can function by, preventing or changing the production of a protein in the cell, particularly beneficial in diseases caused by the overproduction of a specific protein.
