Goodbye fillings, hello laser-treatment? Certainly a medical breakthrough to watch.

No more fillings! Scientists have figured out how to regenerate dentin, the material inside our teeth, and all it takes is a quick blast with a low-powered laser.

Teeth is the only part of the body that cannot repair itself…bull i say

So teeth do not grow back but scientists are trying to stimulate stem cells in the teeth to regenerate denten! It actually sounds pretty interesting, the article that the above article sources can be found here, here’s an except too, if you’re on a phone or something: 

Teeth don’t grow back, as your dentist might like to remind you while revving up the drill for a root canal. But scientists have now found a way to regenerate dentin, the hard stuff in the middle of the tooth, right in the mouth. It’s surprisingly simple, too—all it takes is a blast of laser.

In a study published today in Science Translational Medicine, a Harvard-led team lays out how a low-power laser can trigger stem cells in the tooth to form dentin. Currently, damaged dentin is replaced with synthetic material, like when you get a filling or a root canal.

The current study builds on years of anecdotal reports about low-power laser stimulating skinor hair growth. (Yes, at the same time high-power lasers do the opposite.) Something about laser light stimulates certain biological pathways in cells. Scientists have now figured what thatsomething is when it comes to dentin. A blast of laser induces reactive oxygen species, which are chemically active molecules that then activate a growth factor to stimulate dentin growth.

Although studies have regenerated parts of a tooth from stem cells in a petri dish before, the laser procedure can happen right in the mouth. This study’s authors got it to work in tiny rodent teeth, and now they’re continuing onto human clinical trials in hope it could someday replace some current dental procedures. I don’t know if the thought of even low-power lasers makes the dentist less terrifying, but I’d take it over a root canal. [Science Translational Medicine]

Also, here’s a link to the original paper, I’ve not read it and I think it might be behind a paywall so I’ll try to get better info for it. I really appreciate people asking/commenting about things instead of just hitting ‘reblog’ btw, even if I get called out or someone calls bull or bias, I would rather have that than people not thinking at all!

Wireless power induction could revolutionize medical treatments.

Could New Wireless Power Transfer Unleash Electric Medicine?

Stanford University engineers say they have figured out a way to wirelessly send electric power deeper into the body than ever before.

Inventor and electrical engineering assistant professor Ada Poon created a near-field power transmitter like those used to recharge wireless toothbrushes in their cradle. The difference is that hers uses tissue between the transmitter and medical device implanted in the body to amplify the electromagnetic waves. Her team then created an electrode and receiver unit about the size of a grain of rice that can be placed wherever electrical stimulation is required.

Clone embryos from stem cells - a medical first.

kqedscience:

First Human Clone Embryos Created From Adults’ Skin Cells

"Scientists have created cloned embryos from the cells of two adults. This feat is the first hard evidence that it’s possible to create clones from cells taken from adult humans. The idea is that in the future, doctors could create cloned embryos of patients when the patients need an organ transplant, for example, or a set of new immune cells. The cloned embryos would serve as a source of stem cells for creating perfectly personalized transplants, no matter how old people are when they first get sick."

This paper microscope is simply brilliant design.

IF EVER a technology were ripe for disruption, it is the microscope. Benchtop microscopes have remained essentially unchanged since the 19th century—their shape a cartoonist’s cliché of science akin to alchemical glassware and Bunsen burners. And that lack of change has costs. Microscopes are expensive (several hundred dollars for a reasonable one) and need to be serviced and maintained. Unfortunately, one important use of them is in poor-world laboratories and clinics, for identifying pathogens, and such places often have small budgets and lack suitably trained technicians.

Innovative Smart contacts to monitor glucose levels.

Google unveils ‘smart contact lens’ to measure glucose levels

Google has said it is testing a “smart contact lens” that can help measure glucose levels in tears. It uses a “tiny” wireless chip and a “miniaturised” glucose sensor embedded between two layers of lens material. The firm said it is also working on integrating tiny LED lights that could light up to indicate that glucose levels have crossed certain thresholds. But it added that “a lot more work” needed to be done to get the technology ready for everyday use. “It’s still early days for this technology, but we’ve completed multiple clinical research studies which are helping to refine our prototype,” the firm said in a blogpost. “We hope this could someday lead to a new way for people with diabetes to manage their disease.” (via BBC News - Google unveils ‘smart contact lens’ to measure glucose levels)

Uterine transplants in Sweden.

Doctors in Sweden say nine women have successfully received transplanted wombs and will soon try to become pregnant. But the radical new procedure, which relies on donations from living relatives, has its critics.

To date, no baby has ever been born from a transplanted womb. Two previous attempts, one in Saudi Arabia and one in Turkey, both failed to produce babies. But the new procedure, which is 10 years in the making, appears to be quite promising — so promising, in fact, that embryos may be planted later this year. (via Io9)
