Lasers: A new way to map the brain!

pixabay lasersResearchers have found a way to map the brain using lasers! Chemists from Stanford University have come up with a way to track blood vessels in the brain in a new, non-invasive technique. Ultimately, this research could help improve the understanding of Alzheimer’s Disease.

Current methods for investigating the brain are either too invasive or not detailed enough. Surgery can cause trauma that can negatively impact brain activity, and while MRIs and CT scans can give a good amount of information, sometimes it just isn’t enough.

That’s where this new technique comes in. Researchers inject water-soluble carbon nanotubes into a mouse’s bloodstream. These nanotubes fluoresce at particular wavelengths, so when researchers shine a near-infrared laser over the mouse’s skull, they can see the nanotubes, which show the structures of blood vessels. Scientists were able to see about 3mm underneath the scalp, and this technique doesn’t appear to have any negative effects on brain functions.

This research was developed in mice, but it may be able to be used in humans as well. The technique would need to be modified to allow researchers to see deeper into the brain, and they would need to identify an appropriate fluorescing agent to use. But hopefully, this new technique could give researchers a new way to study strokes, migraines, Alzheimer’s, and Parkinson’s diseases.┬áRead more about it here:

YOUR golden retriever could save lives!

golder retriever puppies with motherOK, I’m not assuming that your golden retriever is going to rescue mudslide victims, sniff out bombs or┬ádetect low blood sugar levels. But if you have a golden retriever, it’s entirely possible that your dog could help save lives by advancing scientific knowledge. Interested?

The Morris Animal Foundation’s Golden Retriever Lifetime Study is enrolling golden retrievers in an attempt to learn how to prevent cancer and other diseases in dogs. They’re hoping to enroll 3,000 dogs- could your dog be one of them? Click here to find out more about the study.

Golden retrievers are awesome. They’re one of the most popular breeds, but unfortunately, many die of cancer. Information gained from the dogs in this study will benefit all breeds and could possibly help humans, too. And it’s an easy enough job; during annual vet visits, it’s as simple as quick blood and urine samples sent off for analysis.

Do you own a golden? Do you have a friend with a golden retriever? Pass this along; let’s help them fill this study!
