Like many conditions, common underlying causes for insomnia often lie in our diet, exercise habits (or lack thereof), and stress. Even other mental health diagnoses may present symptoms that affect our ability to fall asleep and stay asleep. For some, sleeping medication is a reliable treatment, but the mysteries around the human sleep cycle make medication not an option for everyone. Side effects like potential dependence, memory issues, and ironically, drowsiness. Lucky there are other treatments, and many in development, for those suffering with sleep disorders, other than medication.Because of the sensitive and highly individualized nature of sleep, therapeutic and personal approaches to sleep disorders have been looking towards sleep hypnosis methods. Much more than just a (...)
New color-coding tool sheds light on blood disorders, cancers by tracking clonal stem cells
News Medical Life Sciences
▻http://www.news-medical.net/news/20161122/New-color-coding-tool-sheds-light-on-blood-disorders-cancers-by-tracki
A new color-coding tool is enabling scientists to better track live blood stem cells over time, a key part of understanding how blood disorders and cancers like leukemia arise, report researchers in Boston Children’s Hospital’s Stem Cell Research Program.
In Nature Cell Biology they describe the use of their tool in zebrafish to track blood stem cells the fish are born with, the clones (copies) these cells make of themselves and the types of specialized blood cells they give rise to (red cells, white cells and platelets). Leonard Zon, MD, director of the Stem Cell Research Program and a senior author on the paper, believes the tool has many implications for hematology and cancer medicine since zebrafish are surprisingly similar to humans genetically.
[...]
“It’s like an RGB television set, where red, blue and green give you the whole spectrum of colors,” explains Zon. “In our system, the enzyme cuts out different parts —blue, for example, or green and blue — so the stem cell will end up a different shade of color. In this way, we were able to mark each stem cell being born with a different color, and then follow the colors through development and see how many stem cells of each color were present in the adult fish.”
Other scientists have developed tracking systems based on genetic “barcodes.” But these require dissecting the cells, so cannot analyze living, circulating cell populations.

While the research involved only 18 patients and was designed primarily to look at the safety of such a procedure and not its effectiveness, it is creating significant buzz in the neuroscience community because the results appear to contradict a core belief about brain damage — that it is permanent and irreversible.
The results, published in the journal Stroke, could have implications for our understanding of an array of disorders including traumatic brain injury, spinal cord injury and Alzheimer’s if confirmed in larger-scale testing.
The work involved patients who had passed the critical six-month mark when recoveries generally plateau and there are rarely further improvements. [...]
The one-time therapy involved surgeons drilling a hole into the study participants’ skulls and injecting stem cells in several locations around the area damaged by the stroke. These stem cells were harvested from the bone marrow of adult donors. While the procedure sounds dramatic, it is considered relatively simple as far as brain surgery goes. The patients were conscious the whole time and went home the same day.
[...]
“Their recovery was not just a minimal recovery like someone who couldn’t move a thumb now being able to wiggle it. It was much more meaningful. One 71-year-old wheelchair-bound patient was walking again,” said [Gary] Steinberg [the study’s lead author and chair of neurosurgery at Stanford] who personally performed most of the surgeries.
[...]
Steinberg said that the study does not support the idea that the injected stem cells become neurons, as has been previously thought. Instead, it suggests that they seem to trigger some kind of biochemical process that enhances the brain’s ability to repair itself.
“A theory is that they turn the adult brain into the neonatal brain that recovers well,” he explained.
[...]
Nicholas Boulis, a neurosurgeon and researcher at Emory University, said the study appears to support the idea that there may be latent pathways in the brain that can be reactivated — a theory that has been “working its way to the surface” over the past few years.

No Alcohol for Sexually Active Women Without Birth Control, #C.D.C. Recommends

Sexually active women who are not on birth control should refrain from alcohol to avoid the risk of giving birth to babies with fetal alcohol spectrum disorders, even if those women are not yet known to be pregnant, the Centers for Disease Control and Prevention has recommended.
The C.D.C. report, released on Tuesday, estimated that 3.3 million women between the ages of 15 and 44 who drink alcohol risk exposing their infants to the disorders, which can stunt children’s growth and cause lifelong disabilities. The report, which appeared to refer exclusively to heterosexual sex, also said that three in four women who intend to get pregnant do not stop drinking alcohol when they stop using birth control.
“The risk is real. Why take the chance?” Anne Schuchat, principal deputy director of the C.D.C., said in a statement.

The Security Service of Ukraine has said it is well-informed on the plans of the Communists to organize provocations on May 1-2, SBU chief advisor Markiyan Lubkivsky said.
Commémorer le massacre d’Odessa le 2 mai relève évidemment de la provocation.
Lors des bagarres du 14 octobre devant le parlement de Kiev l’un des « activistes » maniait une chaîne (mais pas que…, il est facilement repérable avec son sweat-shirt vert, on le voit avec pavé, fronde vers les policiers et les journalistes,…) aurait été arrêté.

Are We Prepared for the Hard Choices That Prenatal Genetic Tests Could Force on Expectant Parents? | MIT Technology Review
▻http://www.technologyreview.com/review/522661/too-much-information
The catch, though, is that as the accuracy of these tests continues to improve, they will be able to detect a greater range of genetic variations, including some with murkier implications. For example, rather than indicating something with certainty, they could reveal elevated risks for certain diseases or disorders. These advances could collide with the politics of abortion and raise the ugly specter of eugenics. When, if ever, should parents terminate pregnancies on the basis of genetic results? Do we have the wisdom to direct our own evolution? And perhaps most important, are there limits to how much data parents should have—or want to have—about their children before birth?
Nevertheless, that information is coming, and parents will have to figure out what they want to know and how to interpret the choices they’re offered. It is critical, then, that the informed–consent process for testing be exceptionally good, says Greely. Ideally, parents should meet with a genetic counselor to discuss what exactly testing might reveal and what wrenching decisions might follow. If formal genetic counseling isn’t available, obstetricians should step in with extended, thorough conversations that take into account the parents’ values, desire for data, and tolerance for uncertainty. Genetic testing, as Greely puts it, should be made distinct from other forms of prenatal care; it should never be “just one more tube of blood” taken in the course of another whirlwind visit to the doctor.
Household chemicals possibly causing cancers, fertility problems

The significant growth in many human diseases and disorders in recent decades, including breast and prostate cancer, male infertility and diabetes is connected to the rising levels of exposure to mixtures of some chemicals in widespread use, according to a review of recent literature commissioned by the European Environment Agency (EEA).
Chemicals which disrupt the hormone system – also known as ‘endocrine disrupting chemicals’ (EDCs) – can be found in food, pharmaceuticals, pesticides, household products and cosmetics.
The Top 10 Weird Children Of Video Games and Neuroscience

I believe we’re only at the beginning of the cross-pollination between games and neuroscience. Games are helping us unravel things we didn’t know about the brain, from disorders like addiction and amnesia to the processing of pain and visual information. Games are tackling some of the pressing medical issues of our time, including physical rehabilitation and the challenges of an aging population. They’re also teaching us about the way we feel rewarded, and even how we define our sense of self. And as far as neuroscience being on the brink of all its great discoveries, if you ask me, I think Max was right.
