Why Insulin Is a New Suspect in Alzheimer’s Disease

Posted by in categories: biotech/medical, neuroscience

Johnson and Johnson recently announced that it was halting a clinical trial for a new Alzheimer’s drug after safety issues emerged. This latest failure adds to the dozens of large, costly clinical trials that have shown no effect in treating this devastating disease.

The growing list of failures should give us pause for thought – have we got the causes of Alzheimer’s all wrong?

In the first analysis of the disease, the German physician, Alois Alzheimer, noted odd changes in the brain of a patient who died of the condition. Alzheimer identified two kinds of protein aggregates that are not found in younger brains: plaques that are found between brain cells and tangles that are found inside brain cells.

Study finds training-induced neuroplasticity even in patients with chronic traumatic brain injury (TBI)

Very promising since “Identifying what changes are happening in the brain when interventions successfully reduce depressive symptoms could allow us to create more effective, pharmaceutical-free approaches to help alleviate depression in people who experience chronic traumatic brain injury symptoms,” said study author Dr. Sandra Bond Chapman, founder and chief director of the Center for BrainHealth.


Images show prefrontal connectivity patterns after cognitive training in individuals who suffered traumatic brain injury.

Wireless System Can Power Smart Devices Inside the Body

Posted by in categories: biotech/medical, computing, neuroscience

MIT researchers, working with scientists from Brigham and Women’s Hospital, have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light.

The implants are powered by radio frequency waves, which can safely pass through human tissues. In tests in animals, the researchers showed that the waves can power devices located 10 centimeters deep in tissue, from a distance of 1 meter.

Mitochondrial dysfunction in aged brain cells

Posted by in categories: biotech/medical, life extension, neuroscience

New research on brain ageing and mitochondria from Salk Institute.


Thanks to a new technique, researchers from the Salk Institute’s Gage laboratory have shown that impaired energy production might be a reason why human brains are susceptible to age-related diseases in the first place [1].

In particular, Salk scientists observed that induced neurons (iNs) obtained from fibroblasts of older individuals had dysfunctional mitochondria and therefore decreased energy levels compared to younger neurons. Out-of-shape mitochondria have previously been implicated in degenerative brain diseases, such as Alzheimer’s and Parkinson’s, and this finding might help reveal more about the connection between these diseases and this particular hallmark of aging.

The Birth of Wetware

Posted by 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 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 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.
