The glasses, developed over ten years, can guide people living with early-stage dementia through daily activities by identifying everyday objects and providing audio commentary and putting up visual prompts.

If we told them to look at the face, they could usually manage it. But they were mostly looking at the hands. The Prakash children eventually learn to look at faces when spoken to - usually a few months after their surgeries. Their experiences reveal that seeing doesn't come naturally the moment a person is cured of blindness. Newly-sighted people must learn to see.

Red light therapy can help energize hair follicles, increase blood circulation in the scalp, reduce inflammation, and lower dihydrotestosterone levels-a hormone that causes hair loss and thinning. Red light therapy also supports adenosine triphosphate (ATP) production, which helps provide oxygen and blood flow to the scalp and triggers follicles to remain in the hair growth phase.

Complex 3D structures of cells called organoids could be used to test treatments for spinal-cord damage that can lead to paralysis.

Artificial intelligence (AI) machine learning is making a difference in assistive technology to help restore movement for the paralyzed. A new study in the American Institute of Physics journal APL Bioengineering shows how AI has the potential to restore lower-limb functions in those with severe spinal cord injuries (SCIs) by identifying patterns in brain signals captured noninvasively via electroencephalography (EEG).

When I take a walk in my neighborhood, my white hair, dark glasses, and white cane shout to the world that I am an older blind man. Some passers-by assume that I am lost and ask if I need help. It is true that blind people sometimes need help when using a mobility aid (a white cane or guide dog) to navigate their physical environment. However, once a person becomes proficient at traveling with a mobility aid, they typically need much less help.

Before treatment began, participants underwent neuroimaging. Instead of relying on a single modality, the researchers fused structural connectivity (how regions are physically wired) with functional connectivity (how regions co-activate at rest). The goal was not to throw every possible feature at a black box, but to learn a constrained pattern-what the authors call structure-function "covariation"-that carries the most predictive signal for outcome. In other words, the model tries to find the smallest set of connections that meaningfully forecasts symptom change.

EMPAVELI is the first and only approved treatment for C3G and IC-MPGN across pediatric patients 12+, adults, and post-transplant recurrence. That's roughly 5,000 patients in the U.S., with EMPAVELI holding exclusive approval for about two-thirds. Add the European CHMP positive opinion in December 2025, and you have a rare disease franchise with global expansion potential and pricing power that typically commands gross margins north of 90%.

When a person suffers a stroke, physicians must restore blood flow to the brain as quickly as possible to save their life. But, ironically, that life-saving rush of blood can also trigger a second wave of damage - killing brain cells, fueling inflammation and increasing the odds of long-term disability. Now, in a study published in the journal Neurotherapeutics, Northwestern University scientists have developed an injectable regenerative nanomaterial that helps protect the brain during this vulnerable window.

A 33-year-old man survived for 48 hours without his lungs, after a medical team replaced the organs with an external artificial-lung system that it developed to keep him alive until he could receive a double lung transplant. There have been cases in which people have had their lungs removed and been connected to an external device to maintain oxygen levels.

'Stem cell-based' treatments and just the latest aesthetic treatment marketed to those seeking to maintain or obtain youthful skin, but what exactly is involved and what's the evidence that they work It's hard to keep track of the number of scientifically based beauty treatments on offer these days. Most are aimed at middle-aged females with disposable incomes, who are willing to splash large amounts of money on their skin to counter the effects of time.

When Dr. Homoud Aldahash started the three-hour process of removing a tumor about the size of a walnut from a patient's brain, it was an experience unlike any other in his 25 years as a neurosurgeon. It wasn't Aldahash's gloved hands slicing 68-year-old Mohammed Almutrafi's right frontal lobe, but surgical instruments attached to a set of robotic arms, which Aldahash controlled from a console where he sat three meters away.
