Nobel laureate details new applications at Kuh Distinguished Lecture.

Jennifer Doudna, Nobel laureate and Li Ka Shing Chancellor’s Chair and Professor in the Departments of Chemistry and of Molecular and Cell Biology, presented this year’s Ernest S. Kuh Distinguished Lecture, “Delivering the Future of CRISPR-Based Genome Editing,” on February 2 at UC Berkeley. The sold-out event — produced by Berkeley Engineering in collaboration with the Society of Women Engineers — marks the 11th talk in the lecture series, which features scientists and engineers tackling the world’s most pressing problems.

Doudna is known for developing CRISPR-Cas9, a groundbreaking technology that some call “genetic scissors.” With it, scientists can snip and edit DNA — the genetic code of life — unlocking remarkable possibilities in biology, including treatments for thousands of intractable diseases. This work has changed the course of genomics research, allowing scientists to rewrite DNA with unprecedented precision, and won Doudna and collaborator Emmanuelle Charpentier the 2020 Nobel Prize in Chemistry.

Nuclear physicists have discovered gravity’s profound influence on the quantum scale, revealing the strong force’s distribution within protons for the first time. This groundbreaking research, combining historical theoretical insights with modern experimental data, offers unprecedented understanding of the proton’s internal dynamics and sets the stage for future discoveries in nuclear science.

Gravity’s influence is unmistakably evident throughout the observable universe. Its effects are observed in the synchronized orbits of moons around planets, in comets that deviate from their paths due to the gravitational pull of large stars, and in the majestic spirals of enormous galaxies. These magnificent phenomena highlight the role of gravity on the grandest scales of matter. Meanwhile, nuclear physicists are uncovering the significant contributions of gravity at the very smallest scales of matter.

New research conducted by nuclear physicists at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility is using a method that connects theories of gravitation to interactions among the smallest particles of matter to reveal new details at this smaller scale. The research has now revealed, for the first time, a snapshot of the distribution of the strong force inside the proton. This snapshot details the shear stress the force may exert on the quark particles that make up the proton. The result was recently published in Reviews of Modern Physics.

The Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT has developed a new way for LLMs to explain the behavior of other AI systems.

The method is called Automated Interpretability Agents (AIAs), pre-trained language models that provide intuitive explanations for computations in trained networks.

AIAs are designed to mimic the experimental process of a scientist designing and running tests on other computer networks.

A new Northwestern Medicine study has found the immune system in the blood of Alzheimer’s patients is epigenetically altered. That means the patients’ behavior or environment has caused changes that affect the way their genes work.

Many of these altered immune genes are the same ones that increase an individual’s risk for Alzheimer’s. Northwestern scientists theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factors and behaviors.

“It is possible that these findings implicate the peripheral immune response in Alzheimer’s disease risk,” said lead investigator David Gate, assistant professor of neurology at Northwestern University Feinberg School of Medicine. “We haven’t yet untangled whether these changes are reflective of brain pathology or whether they precipitate the disease.”

Matching quantum computing with Tensor networks, and varying then to get the data you need. It’s a good read, about 4 minutes and goes into more detail. Apparently there’s no errors like there is in quantum computing with some adjustments.

Quantum computing has long been celebrated for its potential to surpass traditional computing in terms of speed and memory efficiency. This innovative technology promises to revolutionize our ability to predict physical phenomena that were once deemed impossible to forecast.

The essence of quantum computing lies in its use of quantum bits, or qubits, which, unlike the binary digits of classical computers, can represent values anywhere between 0 and 1.

Minas, known for its Death Star like crater on its surface, is home to a relatively young ocean that’s influencing its orbit.

Inflammation is the signature characteristic of arthritis. Quite literally, “arthritis” means swelling or inflammation of a one or more joints. A common diagnosis among older individuals, the primary cause is inconclusive, but the medical community agrees that it is most likely the cause of disease, genetic defect, an injury, or overuse. The major symptoms include joint pain and stiffness. There are many different types of arthritis, which can have varying symptoms and dictate treatment. Two of the most common include osteoarthritis and rheumatoid arthritis (RA).

Osteoarthritis is caused by the deterioration or break down of cartilage. Cartilage is the slick tissue between bones to allow for easy movement. Rheumatoid arthritis occurs when the immune system attacks the joints. There are many different treatments to target arthritis, but the overall goal is to reduce symptoms and improve the patient’s quality of life. Researchers are currently finding new ways to overcome the disease and possibly reverse the effects of inflammation.

Pure water is an almost perfect insulator.

Yes, water found in nature conducts electricity – but that’s because of the impurities therein, which dissolve into free ions that allow an electric current to flow. Pure water only becomes “metallic” – electronically conductive – at extremely high pressures, beyond our current abilities to produce in a lab.
