Drug repairs systems that remove Alzheimer’s-causing waste from the brain, study shows
by Andrew Smith, Rutgers University Graphical abstract. Credit: Journal of Clinical Investigation (2023). DOI: 10.1172/JCI171468A team of Rutgers undergraduates has shown that an experimental drug known as Yoda1 may help drain cranial waste plus neurotoxins that cause Alzheimer’s disease and other forms of dementia. “The brain’s lymphatic system is one of the hottest research areas in...
Neural network model identifies distinct brain organization patterns in women and men
by Stanford University Medical Center Credit: Pixabay/CC0 Public DomainA new study by Stanford Medicine investigators unveils a new artificial intelligence model that was more than 90% successful at determining whether scans of brain activity came from a woman or a man. The findings, published Feb. 19 in the Proceedings of the National Academy of Sciences, help...
Researchers are using RNA in a new approach to fight HIV
You know mRNA, now meet siRNAPeer-Reviewed Publication UNIVERSITY OF WATERLOO Society learned about the value of mRNA during the COVID-19 pandemic when we saw scientists and medical professionals harness its power to deliver a vaccine for the virus within a year. Now, University of Waterloo pharmacy associate professor Emmanuel Ho has developed a novel nanomedicine...
Treating liver cancer with microrobots
The idea of injecting microscopic robots into the bloodstream to heal the human body is not new. It’s also not science fiction. Guided by an external magnetic field, miniature biocompatible robots, made of magnetizable iron oxide nanoparticles, can theoretically provide medical treatment in a very targeted manner. Until now, there has been a technical obstacle:...
Mind-reading devices are revealing the brain’s secrets
Implants and other technologies that decode neural activity can restore people’s abilities to move and speak — and help researchers to understand how the brain works. By Miryam Naddaf Scientists have studied how brain–computer interfaces, such as this non-invasive cap, change brain activity. Credit: Silvia Marchesotti Moving a prosthetic arm. Controlling a speaking avatar. Typing...
Mapping potential pathways to motor neuron disease treatment

Credit: Dr Rebecca San Gil at the Queensland Brain InstituteFor the first time, researchers from the University of Queensland (UQ) have mapped out the proteins implicated in the early stages of motor neuron disease (MND). Dr. Rebecca San Gil from Associate...
Neuronal diversity impacts the brain’s information processing
by Melissa Rohman, Northwestern University Spike threshold heterogeneity affects the function generation properties of spiking neural networks. (A) Reservoir computing architecture used for function generation. A pulse is fed into a recurrent neural network and a linear readout is trained to minimize the mean squared error between a target time-dependent function and a network output obtained...
Woman in ‘shock’ over $6,000 bill for lifesaving rabies treatment
by Skyler Swisher, Caroline Catherman, Orlando Sentinel Credit: Unsplash/CC0 Public DomainFollwoing a a suspected bat bite Caroline Ford, worried she may have been exposed to rabies, sought treatment from AdventHealth Altamonte Springs. She called her insurance company, Anthem Blue Cross, and expected she’d need to pay about $600 based on her conversation over the phone....
Immune system’s moonlighters point the way to a new therapeutic target
by Cold Spring Harbor Laboratory Graphical abstract. Credit: Molecular Cell (2024). DOI: 10.1016/j.molcel.2024.01.007Our immune system is remarkably powerful. It quickly assembles teams of cells to eliminate threats inside our bodies. But sometimes, it hits the wrong target. Autoimmune diseases like lupus and multiple sclerosis result from friendly fire—immune cells attacking healthy tissues and organs by mistake....
