Neurodegenerative disorders entail a progressive loss of neurons in cerebral and peripheral tissues, coupled with the aggregation of proteins exhibiting altered physicochemical properties. Crucial to these conditions is the gradual degradation of the central nervous system, manifesting as impairments in mobility, aberrant behaviors, and cognitive deficits. Mechanisms such as proteotoxic stress, neuroinflammation, oxidative stress, and programmed cell death contribute to the ongoing dysfunction and demise of neurons. Presently, neurodegenerative diseases lack definitive cures, and available therapies primarily offer palliative relief. The integration of nanotechnology into medical practices has significantly augmented both treatment efficacy and diagnostic capabilities.

The world is entering an era where “technology” and “living organisms” merge into one. Most recently, in 2026, a research team from Northwestern University created a landmark breakthrough by developing “Printed Neurons.” These are not designed just to mimic biology—they can actually “transmit signals” to communicate with living brain cells!
Why is this a big deal? Typically, the silicon-based computers we use today operate entirely differently from the human brain. Computers consume massive amounts of power and are rigid. In contrast, our brains use only about 20 watts (less than some lightbulbs) and are incredibly flexible. Creating artificial neurons that “speak the same language as the brain” is the key to treating diseases that were once considered incurable.
Innovations in “Electronic Ink” and “3D Printing“ At the heart of this research lies a leap forward in materials science and engineering: • Nanomaterials (MoS₂ and Graphene): Researchers used these materials to create a specialized “ink” for printing neural networks. These materials are unique for being both flexible and excellent conductors of electricity. • Aerosol Jet Printing: This technology allows for nano-level precision printing on flexible plastic sheets, designed to contour perfectly to human tissue. • Biomimicry: These artificial cells can generate electrical signals called “Spikes,” matching the rhythm and speed of actual biological neurons.
Proven! Successful Communication with a “Mouse Brain“ The research team tested the connection between these printed neurons and mouse brain tissue. The results showed that the mouse brain cells could receive and respond to signals from the artificial device as if they were from their own kind. This is vital evidence that humans can create devices that interface seamlessly with the nervous system.
Printed artificial neurons reported by Northwestern University can produce neuron-like electrical spikes and trigger responses in living mouse brain tissue. This video explains what was shown, why it matters for brain-like computing and future neural interfaces, and why it is still early laboratory research, not a human implant.
Scientists may have found a powerful new way to lower “bad” cholesterol, which did not involve the use of statin medicines. In a recent study, researchers used tiny DNA-based molecules to cut levels of LDL (bad) cholesterol by nearly 50% in animal models. This was done without the side effects that are often linked to statins. If these results stay consistent in large human trials, the therapy could become an important option for people who cannot tolerate statins or who still have high cholesterol despite taking them. The study was led by Carles J. Ciudad and Veronica Noe from the University of Barcelona’s Faculty of Pharmacy and Food Sciences and the Institute of Nanoscience and Nanotechnology (IN2UB), working with Nathalie Pamir at the University of Oregon in Portland (United States). It was published in the journal Biochemical Pharmacology.
High LDL cholesterol is one of the biggest risk factors for heart attacks and strokes because it leads to the build up fatty plaques in arteries. Drugs like statins work well for many, but some people suffer from muscle aches, digestive issues, or liver problems and have to stop them. However, the new approach is different. Instead of changing how the liver handles fats, it targets a specific protein in the blood that controls how much LDL stays circulating.
A new autonomous laboratory recently navigated through billions of potential material synthesis recipes to identify brighter, lead-free light-emitting nanomaterials in just 12 hours. The work could accelerate development of safer light-emitting nanoplatelets for use in applications ranging from photodetectors to the production of fuel from solar energy. A paper describing this work appears in Nature Communications.
Nanoplatelets are sheet-like crystals only billionths of a meter thick; in this case, they belong to a family of lead-free “double perovskites,” materials whose atomic recipe can be tuned to control how they absorb and emit light.
“One of the big challenges in developing safer optical nanomaterials is the sheer size of the material universe,” says Milad Abolhasani, Alcoa Professor and University Faculty Scholar in the department of chemical and biomolecular engineering at North Carolina State University. Abolhasani is the corresponding author of the research.
Beautifully executed paper on putting mechanoluminescent nanoparticles into blood circulation of mice which express optogenetic channels. Focused ultrasound can then trigger targeted light emission and control of neural activity in the brain and elsewhere.
A deep-tissue light source made from mechanoluminescent transducers stimulated by focused ultrasound enables wide imaging of live animal vasculature, and modulation of neuronal activity and behaviour.
Diagnosing some diseases could be as easy as breathing into a tube. MIT engineers have developed a test to detect disease-related compounds in a patient’s breath. The new test could provide a faster way to diagnose pneumonia and other lung conditions. Rather than sit for a chest X-ray or wait hours for a lab result, a patient may one day take a breath test and get a diagnosis within minutes.
The new breath test is a portable, chip-scale sensor that traps and detects synthetic compounds, or “biomarkers,” of disease, which are initially attached to inhalable nanoparticles. The biomarkers serve as tiny tags that can only be unlocked and detached from the nanoparticle by a very particular key, such as a disease-related enzyme.
The idea is that a person would first breathe in the nanoparticles, similar to inhaling asthma medicine. If the person is healthy, the nanoparticles would eventually circulate out of the body intact. If a disease such as pneumonia is present, however, enzymes produced as a result of the infection would snip off the nanoparticles’ biomarkers. These untethered biomarkers would be exhaled and measured, confirming the presence of the disease.
Water droplets might seem simple at first. But when nearing evaporation, a desperate power struggle of competing physical forces can emerge, with explosive effects. In a Proceedings of the National Academy of Sciences publication, researchers have taken a closer look at the physics of charged water droplets on frictionless surfaces, observing spontaneous jets of microdroplet emissions. Their insights may open new opportunities in nanoscale fabrication and electrospray ionization.
Professor Dan Daniel, head of the Droplet and Soft Matter Unit at the Okinawa Institute of Science and Technology (OIST) says, “From raindrops to spray coatings, mass spectrometry to microfluidics, sneezes to spacecraft plumes, charged droplets can show up in a surprising wealth of settings. Our observations enable new physical understanding of evaporating charged droplets, with a range of potential industrial applications.”
A new study by a team at Tohoku University, published in Chemical Engineering Journal, has shown that more isn’t always better when it comes to nanoscale chemical reactions. One might think that giving reactants completely unrestricted access to a speed-boosting catalyst would be the fastest way to drive a chemical reaction. Instead, it was shown that hollow nanoreactors can work more efficiently when transport into the reaction space is slightly restricted.
A nanoreactor is a porous shell that surrounds an inner space containing catalytically active nanoparticles. The inner space where reactions occur provides a special environment which opens the door for unique and highly useful chemical reactions. Finding ways to optimize reactions in these confined spaces could help to produce a myriad of everyday products more efficiently, and at a lower price.
While it might seem like flooding this inner space would get things done the fastest, researchers found that the key to optimization involved holding back a little.
Replicating the brain’s capabilities, an impossible task, may theoretically require thousands of H100, one of NVIDIA’s most powerful GPUs. At 700 watts per chip, we are looking at power consumption in the megawatt range. The brain runs on 20 watts. Scientists have taken inspiration from this remarkable organ to create chips that could cut conventional energy use by 70%.
Researchers at the University of Cambridge have developed a new brain-inspired nanoscale device that they say could dramatically reduce the enormous energy demands of artificial intelligence hardware. The team created an ultra-low-power “memristor”: a device that can both store and process information in the same location, much like synapses in the human brain.
In conventional computing architectures, memory and processing units are physically separated, requiring data to shuttle back and forth between these units for every task. This seemingly simple process consumes enormous amounts of electricity and is a significant contributor to AI’s exploding power demands.
