Piezoelectric nanoparticles deployed inside immune cells and stimulated remotely by ultrasound can trigger the body’s disease-fighting response, according to an interdisciplinary team of Boston College researchers.
The paper is published in the journal Scientific Reports.
One of the hallmarks of Alzheimer’s disease is the clumping of proteins called Tau, which form tangled fibrils in the brain. The more severe the clumping, the more advanced the disease is.
The Tau protein, which has also been linked to many other neurodegenerative diseases, is unstructured in its normal state, but in the pathological state it consists of a well-ordered rigid core surrounded by floppy segments. These disordered segments form a “fuzzy coat” that helps determine how Tau interacts with other molecules.
MIT chemists have now shown, for the first time, they can use nuclear magnetic resonance (NMR) spectroscopy to decipher the structure of this fuzzy coat. They hope their findings will aid efforts to develop drugs that interfere with Tau buildup in the brain.
The technology has entered use in recent years, but it isn’t yet fully integrated into research. Now, two MIT researchers are planning experiments with it, and have published a new paper they term a “roadmap” for using the tool to study consciousness.
“Transcranial focused ultrasound will let you stimulate different parts of the brain in healthy subjects, in ways you just couldn’t before,” says Daniel Freeman, an MIT researcher and co-author of a new paper on the subject. “This is a tool that’s not just useful for medicine or even basic science, but could also help address the hard problem of consciousness. It can probe where in the brain are the neural circuits that generate a sense of pain, a sense of vision, or even something as complex as human thought.”
Transcranial focused ultrasound is noninvasive and reaches deeper into the brain, with greater resolution, than other forms of brain stimulation, such as transcranial magnetic or electrical stimulation.
Scientists have identified a promising target for treatment of a devastating autoimmune disease affecting the brain.
The discovery could lead to the development of new therapies for a disease triggered by an attack on one of the key neurotransmitter receptors in the brain, the NMDA receptor. It also raises the potential for a blood test to detect a signal of the condition and enable earlier treatment with existing therapies.
The study from Oregon Health & Science University is published in Science Advances.

“Avian Flu in North America: The D1.1 Evolutionary Leap” explores the emergence of a game-changing H5N1 virus variant that has fundamentally altered North America’s disease landscape since mid-2024. Through accessible explanation of cutting-edge genomic science, this episode reveals how the D1.1 genotype achieved unprecedented spread, infected all seven documented host categories including humans, and represents a major evolutionary shift. The podcast examines the massive computational effort behind tracking viral evolution, exposes critical gaps in our surveillance infrastructure, and confronts a paradigm-shifting reality: the Americas have become a primary engine of H5N1 evolution, reversing decades of global health assumptions.
With rapid advancements in AI and automation, individuals must prepare for a potentially unstable future by building financial strength, adapting to change, and rethinking traditional economic policies to avoid societal collapse ## ## Questions to inspire discussion.
Financial Preparation.
💰 Q: How should I structure my finances to build wealth? A: Focus on the fundamental equation: earn minus spend equals save, then invest that saved amount wisely to determine your financial success, as this simple formula is the foundation of building financial strength.
🏃 Q: When should I consider relocating geographically? A: Evaluate your location during major financial shifts and changing world orders, as the ability to move to better places and away from bad places has been historically important for protecting wealth and opportunity.
Career Strategy.
🎯 Q: How do I choose a career that maximizes financial success? A: Select careers that align with your passions while understanding their financial implications, since the work you do will directly impact your financial success during economic transitions.
How cells eliminate inefficient ribosomes.
Inside every cell, ribosomes act as tiny but vital factories that build proteins, translating genetic information into the molecules that sustain life. Although ribosomes share the same basic structure, not all of them work with equal precision. Until now, scientists did not fully understand how cells detect and handle ribosomes that underperform.
Addressing this question, a team of researchers has identified a quality control mechanism that ensures only the most competent ribosomes survive. Their study, published in Nature Communications shows that ribosomes compete during protein synthesis. When translation is disrupted, the less efficient ribosomes are selectively broken down, while the stronger ones continue functioning.
Using biochemical and genetic analyses in yeast, the researchers examined how ribosomes behave when translation is disrupted. The team engineered cells to contain a functional but suboptimal ribosome variant. These slower-moving ribosomes are overtaken on messenger RNA by faster, native ribosomes, causing the two types to collide. Such ribosome-ribosome collisions activate a ubiquitination-dependent quality control pathway that selectively removes the less efficient ribosomes.
The team also explored how external factors, such as the anticancer drug cisplatin affect this process. Cisplatin, known for binding to RNA and DNA, was found to increase ribosome collisions, which in turn promoted ribosome degradation. This insight could improve understanding of how the drug acts inside cells and why it sometimes causes side effects.
The implications of this discovery extend beyond basic biology. By showing how cells maintain the quality of their protein factories, the study provides a foundation for understanding disorders caused by ribosome malfunction, known as ribosomopathies. It may also open the door to new approaches for improving the safety and effectiveness of certain drugs.
Serum NMDAR autoantibodies are associated with isolated memory deficits in patients with cancer and might serve as a potential biomarker for cancer-related cognitive impairment.
ObjectivesNeuronal autoantibodies are linked to cognitive impairment in neurologic diseases and can be associated with tumors. In patients with cancer, IgA/IgM N-Methyl-D-Aspartate receptor (NMDAR) autoantibodies are most common, yet their clinical relevance is unclear. We assessed cognitive function in cancer patients with serum NMDAR autoantibodies and compared the results with matched controls.
Researchers in China have found no statistically significant advantage for infrapatellar fat pad glucocorticoid injection over saline for 12-week knee pain change or effusion synovitis volume change in inflammatory knee osteoarthritis.
Osteoarthritis affects approximately 595 million people worldwide, with knee joints identified as the most commonly affected. Symptomatic knee osteoarthritis is linked to physical disability, reduced quality of life, and increased mortality in older adults, while curative drugs remain lacking amid a rising burden tied to aging and obesity.
Some knee osteoarthritis involves inflammation, and inflammation can involve two nearby tissues—the fat pad under the kneecap and the joint lining—that are structurally interconnected and serve as important sources of inflammation in knee osteoarthritis.
