The Birth of Wetware
Posted by Marcos Than Esponda in categories: employment, neuroscience
I t’s an odd thing for someone to say about neurons: “Let’s see if anyone is awake.” And it’s an even odder thing to hear in a cavernous, half-furnished office suite where one whole room is occupied only by copy machines and a lonely foosball table.
Not far from that foosball table, Oshiorenoya Agabi and Benjamin Sadrian are sitting in a lab at their startup, Koniku, in Berkeley, California. Agabi founded the company, and Sadrian is a senior neuroscientist. They are toggling between a microscope and a screen full of blue graphs, looking for signs of activity in a cluster of neurons. Sadrian pauses as he scrolls through slightly fuzzy readouts on the screen, reminiscent of stock charts with buzz cuts. “I wish you’d come later, even tomorrow,” he sighs.
These readouts measure signals inside cells, and Agabi and Sadrian are looking for spikes that would show Koniku’s neurons reacting to a chemical Sadrian exposed them to moments ago. When we examined them under the microscope, they glowed a faint neon green, which indicates they’re starting to mature. A few tentative dendrites reached out into the void, the neurons just beginning to form connections with one another. But the telltale spikes don’t materialize on the screen. At just six days old, these neurons are still too young to do the jobs they’ve been engineered to do.

Japan moves to fast-track innovative stem cell therapy with first trials on human hearts
Posted by Genevieve Klien in categories: biotech/medical, life extension, neuroscience
With the ability to be coaxed into different kinds of mature cell types, induced pluripotent stem cells (iPSCs) hold all kinds of potential in the world of regenerative medicine. One of the many possibilities could be repairing damaged hearts, something that will soon be put to the test for the first time ever in newly approved clinical trials in Japan.
Since emerging from the laboratory of researcher Shinya Yamanaka in Japan in 2006, the potential of iPSCs has been explored in all kinds of promising research efforts. We have seen them implanted into rabbits to restore their vision, become brain tumor predators, and turned into precursor cells for human organs.
IPSCs are created by first harvesting cells from body tissues and then infecting them with a virus, in turn introducing them to carefully selected genes that return them to their immature state. From there they can develop into any cell in the body, a capability so powerful it earned Yamanaka a Nobel Prize in 2012.

Neuroscientists Uncover the Roots of the Uniquely Large Human Brain
Posted by Genevieve Klien in categories: evolution, neuroscience
On Thursday, an international team of scientists announced a new explanation for the evolution of brain size expansion: Unique genes that, to date, have only been found in humans. They’re called NOTCHN2NL genes and so far the scientists have identified eight different versions of them.

You’ll soon be able to get a 3D printed model of your brain
Posted by Marcos Than Esponda in categories: 3D printing, biotech/medical, computing, habitats, neuroscience
https://www.engadget.com/…/3D-printed-brain-medical-imagin…/
There are almost limitless possibilities when it comes to 3D printing. Design your own color-changing jewelry? Fine. Fabricate your own drugs? No problem. Print an entire house in under 24 hours? Sure! Now, researchers have come up with a fast and easy way to print palm-sized models of individual human brains, presumably in a bid to advance scientific endeavours, but also because, well, that’s pretty neat.
In theory, creating a 3D printout of a human brain has been done before, using data from MRI and CT scans. But as MIT graduate Steven Keating found when he wanted to examine his own brain following his surgery to remove a baseball-sized tumour, it’s a slow, cumbersome process that doesn’t reveal any important areas of interest.

Age-Related Changes to the Nuclear Membrane Alter Gene Expression
Posted by Manuel Canovas Lechuga in categories: biotech/medical, life extension, neuroscience
Researchers at the University of Virginia School of Medicine have discovered that as we age, our cells’ nuclear membranes become misshapen, which stops our genes from working properly.
Nuclear membranes become distorted with age
The DNA in all our cells is the same; however, the cells in our body show a great range of variation and function. How can this be when they have the same DNA? It all comes down to gene expression and which genes are turned off and which are turned on. For example, certain genes must be turned on in a cell for it to be a liver cell; those same genes need to be turned off for it to be a brain cell. If the correct genes are not turned off, problems occur.

Why living near forests can benefit your mental health
Posted by Shailesh Prasad in categories: health, neuroscience
It is rush hour and you are crammed inside a train carriage with a stranger’s armpit pressing against your face. Are you feeling relaxed?
Studies have shown that repeated infringement of personal space in cities can trigger the brain’s threat system, which makes us feel stressed.
Other factors such as constant contact with strangers and traffic noise all contribute to city dwellers being most likely to suffer from chronic stress.
