Check out the Universe in a Black Hole Merch at the Space Time Merch Store https://www.pbsspacetime.com/shop. Kurt Gödel discovered a solution to General Relativity that allows time travel without any exotic physics, revealing that the theory doesn’t actually guarantee a consistent chain of cause and effect. His “Gödel universe” shows that under certain conditions, the […]

What if the most basic assumptions about reality, that objects are separate, and distance is real… are completely wrong? For centuries, classical physics described a predictable, local universe where nothing influenced anything faster than light. Then, quantum entanglement arrived, breaking our entire assumption of reality and terrifying even the most brilliant minds, including Albert Einstein. […

Advance could suggest new ways to synthesize proteins with bespoke functions in medicine and biotechnology

A blood cancer-protective inherited variant in the homeotic lncRNA HOTSCRAMBL alters HOXA9 splicing, fine-tuning hematopoietic stem cell self-renewal while constraining HOXA-driven blood cancers.

Whether DNA-PKcs is necessary for non-homologous end joining has been biochemically obscure. Through optimization of reaction conditions, Fujii and Modesti show that DNA-PKcs plays a constructive role, which leads to indistinguishable repair efficiencies between cohesive-end and blunt-end DNA substrates.

https://doi.org/10.1172/JCI197923 Here, David A. Brenner & team discover the RNA-binding protein LARP6 as a master coordinator of hepatic stellate cell activation and fibrosis, using human tissue and liver spheroid models of MASH and MetALD. The image shows collagen labeling (red) in human liver spheroids MASH model with LARP6-targeting ASO (DAPI, blue). Collagen labeling is decreased [&#8230…

Just like vertebrates, cephalopods—such as octopuses and squid—have elaborate brains. Neuroscientists are flocking to them for insights into how intelligence evolved.

Researchers at Johns Hopkins Medicine say they have successfully demonstrated that disrupting an eye structure long suspected of blocking the growth and survival of transplanted nerve cells may help restore vision in people with optic nerve damage. A report on the experiments with animals, stem cells and donated eye tissue was published in Science Translational […]

A large-scale brain imaging study of over 800 incarcerated men reveals that highly psychopathic individuals possess an expanded cortical surface area and a compressed physical brain organization, offering new clues into the biology of empathy and antisocial behavior.

Gait impairments such as freezing, weakness and imbalance remain resistant to standard therapies across neurological disorders. This Review examines advances in neuromodulation, from refining deep brain stimulation to integrating spinal and distributed strategies. It discusses adaptive neurotechnologies, mechanistic insights and a framework for tailoring spatiotemporally precise interventions to …

Now, as artificial intelligence enters the classroom, proponents argue it will be a welcome revolution for schools — but with limited guardrails, could it do more harm than good? Horizons moderator William Brangham explores the future of AI and education with Khan Academy founder Salman Khan, who has launched a new AI assistant for teachers. […]

Our most massive satellite galaxy, the Large Magellanic Cloud (LMC), has been the center of a heated debate in the astrophysics community over the last few years. That debate centers on whether this is the LMC’s first or second “pass” by the Milky Way itself — and it has huge implications for the evolution of […]

Russia is developing what officials have described as a “vaccine against aging,” a gene therapy drug aimed at slowing cellular aging by blocking a receptor linked to age-related changes in the body, the deputy science minister said Thursday. Denis Sekirinsky, Russia’s deputy science and higher education minister, said the experimental treatment would target the RAGE […]

Statistics show clear differences in the population’s immune system according to sex: men are more susceptible to infections and cancers, while women have stronger immune responses, which translate, for example, into better responses to vaccines. Even so, with a more reactive immune system, the probability of the body attacking itself also increases, causing 80% of […]

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further. For the first time, researchers have observed wave-like interference in positronium, an exotic “atom” made of an electron and its antimatter partner, a positron. This breakthrough not only strengthens the weird reality of […]

Large language models (LLMs) could help human scientists identify interesting research topics that have not previously been explored, say scientists at Germany’s Karlsruhe Institute of Technology (KIT). By analysing abstracts in materials science publications and mapping connections between different concepts, the model was able to generate predictions for future areas of interest that the KIT [&…

The role of lifestyle interventions in treatment success has become essential for nearly every disease. Healthy dietary habits, regular exercise, and stress management are key pillars that can improve quality of life during treatment, as well as delay disease onset and progression. In this study, we focus on the combination of mild calorie restriction (CR) […]

The emergence of neuropsychiatric disorders, conditions that affect various brain functions and behaviors, is known to be driven by an intricate combination of factors. These can include both a genetic predisposition and exposure to traumatic events or other external circumstances. Over the past decades, many neuroscience studies have tried to shed light on the origins […]

The Academy of Motion Picture Arts and Sciences—probably better known to the world as the Oscars folks—have drawn a firm line in the sand against the use of generative AI, changing its eligibility rules to exclude AI-generated performances and scripts. The new rules, via The Wrap, state that in acting categories, only roles “demonstrably performed […]

According to “industry sources and executives” known to Reuters, the war in Iran is affecting the supply of materials that are crucial for Printed Circuit Boards (PCBs), which has made them shoot up in price. Reuters says that, cccording to Goldman Sachs, PCB prices in April shot up by as much as 40% since March. […]
