You’ll soon be able to get a 3D printed model of your brain

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.

Nanoparticles carry drug duo into the brain to fight cancer
Posted by Genevieve Klien in categories: biotech/medical, nanotechnology, neuroscience
Glioblastoma is one of the most deadly forms of cancer. Affecting the brain, those unlucky enough to receive a diagnosis don’t have many treatment options – and usually a median life expectancy of just over a year. Now, researchers at MIT have developed nanoparticles that could provide hope, crossing the blood-brain barrier and delivering two types of drugs to fight tumors.
The MIT nanoparticles are liposomes, fatty droplets that can carry one drug on the inside and another in the outer layer. On the inside, the particles were loaded with a common chemotherapy drug called temozolomide, while the outer shell contained a more experimental substance known as JQ-1.

Here’s how China is challenging the U.S. and European brain initiatives
Posted by Derick Lee in categories: government, neuroscience
The nascent China Brain Project took another step toward reality last week with the launch of the Shanghai Research Center for Brain Science and Brain-Inspired Intelligence. The new center and its Beijing counterpart, launched 2 months ago, are expected to become part of an ambitious national effort to bring China to the forefront of neuroscience. But details of that 15-year project—expected to rival similar U.S. and EU efforts in scale and ambition—are still being worked out, 2 years after the government made it a priority.
New research centers move 15-year project closer to reality.

Measles makes alarming return to Europe and the Americas
Posted by Genevieve Klien in categories: biotech/medical, economics, health, neuroscience
Why it matters: Measles is a killer disease. It’s estimated that more than 2 million children a year died from measles in the 1980s, but due to global vaccine programs (including Gavi, the Vaccine Alliance launched in 2000), that number has been brought under 70,000 cases. The return of measles to Europe and the Americas could suggest that some of our vaccine successes could be reversing or unraveling. In the case of Venezuela, measles outbreaks are mostly due to the effect of broad economic problems on its health care system, but for Europe and the U.S. measles outbreaks show the effects of powerful and well-organized anti-vaccine movements.
What’s next: Vaccines do not cause autism, but more advocacy is needed to counteract the false claims of anti-vaccine groups. In April 2018, the European Commission proposed activities to strengthen the EU’s capacity to vaccinate its population and address what some call “vaccine hesitancy.” In the U.S., however, there are still 18 states that allow non-medical vaccine exemptions linked to personal or philosophical beliefs.
Peter Hotez is a professor and dean of the National School of Tropical Medicine at Baylor College of Medicine, where he is also director of the Texas Children’s Hospital Center for Vaccine Development, and the author of “Vaccines Did Not Cause Rachel’s Autism.”
