Dr creator....
In an incredibly interesting development, an "artificial womb" has successfully grown sheep from 105-120 days in pregnancy (roughly the equivalent of 22-24 weeks in a human) to full term. The womb consists of a sealed transparent bag, inside which an electrolyte fluid flows, keeps the developing lungs supported, and removes waste (much like amniotic fluid does) and an umbilical blood system which provides nutrients, oxygenates blood, and so on. As you can imagine, this was tremendously difficult to develop -- e.g., the umbilical system can't have its own pump, since that would damage the developing heart, and instead fluids must flow easily enough that the fetus' own heartbeat is enough to keep its circulation going.

What's amazing is that this seems to be working. Eight lambs have been born through the system, and researchers are monitoring them closely to see how they develop.

This isn't a complete uterine replicator; the environment in early development is even more complex than it is in late development, and there's no suggestion that you could start from an embryo or a zygote here. What this could have an effect on is extreme prematurity -- infants delivered at or before the 28th week, who currently have a fairly poor prognosis, both for survival and later quality of life. The further effects that such technologies could have in the future are, of course, even more profound. (And have been discussed at length in the science fictional literature, with Bujold being probably its most famous explorer)

Current estimates suggest that this could be 3-5 years away from the first human tests. Those are likely to be difficult, of course, since human development is more complex than sheep development, especially as regards the brain; however, if applied to extremely premature fetuses, it could be a reasonable experimental treatment as the alternative is even worse.

Hi all, anyone is being treated with plegridy? It has been a very unpleasant night, shivers all over the body, bone pain, headache....
Every time I get my shot I have always severe symptoms; neurologist says it could be better in time but unfortunately it's not and recommends me to switch to tecfidera (dimethyl fumarate).
I do not like to switch my medication carelessly: apart from the severe after shock reaction, plegridy seems to work (no advance in my mri scans).
Is tecfidera easily tolerated? Is as effective as plegridy ( neurologist says it's more effective and has less side effects).

Images are a huge part of bandwidth & data costs online. We're using machine learning to provide 75% bandwidth savings per image served. This is currently rolled out to just a subset of Google+ Android users but already impacting over a billion images per week. More over on the official Google blog:

Lip-reading is notoriously difficult, depending as much on context and knowledge of language as it does on visual clues. But researchers are showing that machine learning can be used to discern speech from silent video clips more effectively than professional lip-readers can.

A researcher at NASA’s Jet Propulsion Lab, Adrian Tang, working with UCLA professor M.C. Frank Chang, has developed a Wi-Fi chip for use in mobile electronics that uses 100 times less power than traditional receivers. This could extend battery life in nearly every device that uses Wi-Fi, and Tang is trying to focus on the expanding market for wearables.
To do something on the internet (like view this website), your smartphone generates and sends a signal out to your router, and your router generates and sends a new signal back to it. Tang’s Wi-Fi chip reflects a constant signal sent by a specialized router, instead of generating its own original signal. Data is imprinted on the signal when it’s reflected, so all the heavy lifting is essentially done on the router’s side.
“Because you’re only imprinting on a Wi-Fi signal, you’re not generating it, you don’t need power,” Tang said.

Harvard scientists think they've pinpointed the physical source of consciousness
Scientists have struggled for millennia to understand human consciousness - the awareness of one's existence. Despite advances in neuroscience, we still don't really know where it comes from, and how it arises.

But researchers think they might have finally figured out its physical origins, after pinpointing a network of three specific regions in the brain that appear to be crucial to consciousness. 

"For the first time, we have found a connection between the brainstem region involved in arousal and regions involved in awareness, two prerequisites for consciousness," said lead researcher Michael Fox from the Beth Israel Deaconess Medical Centre at Harvard Medical School.

The Harvard team has identified not only the specific brainstem region linked to arousal, but also two cortex regions, that all appear to work together to form consciousness.
