QuoteThis wearable brain scanner could transform our understanding of how neurons 'talk'
Mapping the chattering of neurons is a tricky undertaking. Arguably the best tool for eavesdropping in real time—by detecting the weak magnetic fields emitted by communicating neurons—comes with a huge caveat: Participants must keep their heads absolutely still inside an enormous scanner. That makes the method, magnetoencephalography (MEG), a no-go for young children, and it nixes studying brain behavior while people are moving. Now, scientists have developed the first device to solve those problems, a masklike instrument that can transmit brain signals even when the wearer is moving.
Despite some limits on how much of the brain's activity can be mapped at once, neuroscientists are excited. "This is remarkable," says MEG researcher Matti Hamalainen of Massachusetts General Hospital in Boston, who wasn't involved in the study. "MEG is moving forward conceptually into a new era."

I went to the Dermatologist a few days ago. Routine annual exam. I live in the semi tropics and my risk of skin cancer is worth monitoring. Sure as hell he found three little disturbances that he sliced open. He says that little chunks of me will be sent away to the laboratory to determine whether the cells are malignant. Meanwhile I have to wait, and of course I will have to pay for the follow up visit and probably the charges from the lab.
One of the freakin' tiny places is below my right eye, dangerously close to the eye. Whaaaat? Yeah, he sliced a chunk of that flesh out so that the lab could do their thing. Sheeeit, I did not even know that there was any sign of a problem on or near my eye. I cannot help but wonder whether the doctor was hustling me. He has a good reputation but reputations are made by patients who are satisfied that the man is sincere and caring and all that stuff. Patients do not know shit about what is going on so how could we make a reliable assessment of the competence or integrity of the practitioner?
Ours is a fee for service economy. The more a physician, Lawyer or accountant can have you involved, the more secure his/her practice.
The magic pen could change the way these things are done.

I occasionally get little spots as well, because I am very light-skinned. They usually get fixed very easily with a painless cryo non-surgical treatment. My doctor dips a cotton bud in liquid nitrogen and then freezes the spot. It usually clears within a week, but the secret is to catch them early, before they become problematic.
Yes, here's hoping it's just one of those non-nasty things that can afflict us with age.
And I agree about the possibility of "surplus" treatment - there is a dentist in a local praftice thst I have suspicions about . . .

Eeek! I sure hope all is well!
There are three varieties of mole like skin cancer. the first two are not lethal. The last one, Melanoma, can be a serious or even fatal problem if not attended promptly. I have had only minor bouts with those skin lesions. The dermatologist will usually want to remove squamish cell growths, the number two type. It will not kill you but it will continue to grow if not removed....eeek whacking away flesh and usually cauterizing the closure. I do not like the smell of burning flesh, and especially when it is my flesh. The least of the skin lesions are often literally "burned" off with a stream of liquid nitrogen. Damn that hurts, but it does get rid of the mini cancers.
All the skin cancers are said to be caused by UV radiation, as in sunshine. Tanning beds are a prime cause of those cancerous thingies. Since I am told that the sun seldom shines in England, you will not be as much at risk...... or if I am to believe the lyrics of a certain, I think, Gilbert and Sullivan opera...."Only mad dogs and Englishmen go out in the noonday sun".....or is that Kipling?
The use of various lotions to combat the dry or flaky skin has its downsides. Commonly prescribed lotions such as ammonium lactate are just fine except that it makes the skin more sensitive to UV radiation and therefore more likely to produce cancerous cells.
I think another downside of sunscreen is it impairs vitamin D production? Not that it's a huge problem, people can always take supplements...better to use lotion.
I should take my own advice. ::) I don't use sunscreen even though I should.

There is a much higher awareness of these things in sunny countries like Australia and South Africa with very large Caucasian populations. Most of our GPs routinely check for suspicious spots when one visits them.

My year in Bahrein gave me enough sunshine to kast me the rest of my life without ever wanting to be in it, unnecessarily, again!
But, on an archaeological dig during what passes for summer in England, the weather was sunny but the wind on top of that hill was not that warm.
I got laughed at for using factor 15 on my nose, ears and the back of my neck and wearing a large safari hat and long sleeved tee shirts that were a size to big (so they did not ride up above my thin cotton trousers when I bent down). I was the one without nasty sore red bits after two days.

Yeah! Students, eh? Skin tight jeans and cropped tops are not suitable on a sunny hill-top with long periods in one position - would have thought even freshers would have had the advice and stuck to it.
Baggy pants and sloppy tops rule, OK? I had one of the Arabic thobs, from Bahrein, but decided not to wear that.

Silver...are you there?.....Help. This morning the NPR (National Public Radio) program had two medical researcher women who were discussing something that they called kilomeres. (sp). They are a part of the human genome that are made like strings. They vary in length and the shorter they are, the more serious the affect on ones long term health outcome. They used a metaphor about shoestrings with the little plastic tip at the end.

You may be thinking of chromosomes which contain genes, not genes themselves, which contain
other sequences that stop proteins from 'reading' and making other molecules from them. Normal humans have 23 pairs of chromosomes, and all our genes are contained within them.
This is an image from the wiki page showing telomeres (in white), which cap each chromosome a bit like shoelaces are capped with the plastic thingy.

QuoteScientists have 3D printed the most advanced artificial cornea ever using human cells
They're not ready for human eyes yet, but one day these artificial corneas might help people see
Scientists have 3D printed the thin protective film over the eye, called the cornea, using human cells — and it's the most advanced version of an artificial cornea yet. Should the technology improve, it could help millions of people see again.
It was tricky to find the right recipe for an ink that's thin enough to squirt through a 3D printer's nozzle, says Che Connon, a tissue engineer at Newcastle University who was one of the creators of the artificial cornea. This bio-ink didn't just have to be thin — it also had to be stiff enough that it could hold its shape as a 3D structure. To get the right consistency, the researchers added a jelly-like goo called alginate and stem cells extracted from donor corneas, along with some ropy proteins called collagen.

QuotePromise of faster, more accessible schizophrenia diagnosis
Researchers explore eye function in schizophrenia as a window into the brain
A new study shows how the hand-held device RETeval may prove to be a more accessible way to diagnose schizophrenia, predict relapse and symptom severity, and assess treatment effectiveness.
A portable device common in optometrists' offices may hold the key to faster diagnosis of schizophrenia, predicting relapse and symptom severity and assessing treatment effectiveness, a Rutgers University study finds.
In the study, published in the May 2018 issue of the Journal of Abnormal Psychology, researchers used RETeval, a hand-held device developed to record electrical activity from the retina, to replicate and extend prior studies showing that people with schizophrenia had abnormal electrical activity in the retina. This was the first time a portable device was used for these tests. The results show the device accurately indicated reduced electrical activity in the retina in multiple cell layers in the participants who had schizophrenia, including in cell types that had not been studied before in this disorder.

You are probably right to be a bit sceptical, Tank. Thought it worth reporting but the proof of the pudding is in the eating. If statistically significant diagnosese do not occur it will be another pie in the sky.
There have been some new medical glues over the past couple of years and a new one. Voltaglue, has joined the group. It works inside the body on wet stuff and is set (and unset), as its name suggests, using electricity. The amount of energy determines the bond strength, or unbonds.
Quote"Voltaglue" sticks in the wet and hardens when voltage is applied
A glue that performs at a high-level in wet environments could bring about all sorts of possibilities in areas like surgical care and ship maintenance. A somewhat common approach to this problem has been trying to replicate the freakish ability of mussels to bind themselves to boats and jetties, but a team from Singapore's Nanyang Technological University is coming at it from a slightly different angle by developing a glue that hardens when an electrical charge is applied.
