Sleeping on your side may clear waste from your brain most effectively

Posted by in categories: biotech/medical, neuroscience

The brain’s glymphatic pathway clears harmful wastes, especially during sleep. This lateral position could prove to be the best position for the brain-waste clearance process (credit: Stony Brook University)

Sleeping in the lateral, or side position, as compared to sleeping on one’s back or stomach, may more effectively remove brain waste, and could reduce the chances of developing Alzheimer’s, Parkinson’s and other neurological diseases, according to researchers at Stony Brook University.

Stony Brook University researchers discovered this in experiments with rodents by using dynamic contrast magnetic resonance imaging (MRI) to image the brain’s glymphatic pathway, a complex system that clears wastes and other harmful chemical solutes from the brain. They also used kinetic modeling to quantify the CSF-ISF exchange rates in anesthetized rodents’ brains in lateral, prone, and supine positions.

Intracellular microlasers for precise labeling of a trillion individual cells

Posted by in category: biotech/medical

Massachusetts General Hospital investigators have induced subcutaneous fat cells in a piece of skin from a pig to emit laser light in response to energy delivered through an optical fiber (credit: Matjaž Humar and Seok Hyun Yun/Nature Photonics)

Imagine being able to label a trillion cells in the body to detect what’s going on in each individual cell.

That’s the eventual goal of a Massachusetts General Hospital (MGH) study to allow individual cells to produce laser light. The wavelengths of light emitted by these intracellular microlasers differ based on factors such as the size, shape, and composition of each microlaser, allowing precise labeling of individual cells.

A (Very) Brief History of Death

“I am prepared to meet my Maker. Whether my Maker is prepared for the great ordeal of meeting me is another matter.” — Winston Churchill

Death still enjoys a steady paycheck, but being the Grim Reaper isn’t the cushy job that it used to be.

Microsoft Works Out How to Upgrade Online Encryption to Protect Against Quantum Computers

Posted by in categories: biotech/medical, computing, encryption, energy

Call it an abundance of caution. A Microsoft research project has upgraded the encryption protocol that secures the Web to resist attacks from quantum computers—machines that are expected to have stupendous power but have never been built.

Governments and computing giants like IBM, Microsoft, and Google are working on quantum computers because tapping subtle effects of quantum physics should let them solve in seconds some problems that a conventional machine couldn’t solve in billions of years (see “Microsoft’s Quantum Mechanics”). That might allow breakthroughs in areas such as medicine or energy. But such machines would also be able to easily break the encryption used to secure information online.

Synthetic biology – the next big thing

Posted by in categories: biotech/medical, chemistry, nanotechnology

Synthetic biology programming microorganisms to perform some new functions. Genes are made out of DNA; synthetic biology involves inserting synthetic genes that might not have existed before into yeast and reprogramming them to make a new chemistry or things not made naturally by biology. Each gene codes for an enzyme. One can program a new set of enzymes and convert them to intermediate products. If you go through five or even 15 steps, you can get a final product – a polymer, a new drug – creating a chemical factory inside a cell. This is much better than nanotechnology, because in synthetic biology, we get down to molecular size…


Prof. Joseph Jacobson, a leading physicist at the Massachusetts Institute of Technology, is not only the inventor of e-ink but also a mover in creating artificial DNA to eventually cure diseases.

Affordable genetic diagnostic technique for target DNA analysis developed

Posted by in categories: biotech/medical, chemistry, engineering, genetics

Professor Hyun-Gyu Park of the Department of Chemical and Biomolecular Engineering at Korea Advanced Institute of Science and Technology (KAIST) has developed a technique to analyze various target DNAs using an aptamer, a DNA fragment that can recognize and bind to a specific protein or enzyme. This technique will allow the development of affordable genetic diagnosis for new bacteria or virus, such as Middle Ease Respiratory Syndrome (MERS). The research findings were published in the June issue of Chemical Communications, issued by the Royal Society of Chemistry in the United Kingdom. The paper was selected as a lead article of the journal.

Bioviva is moving into telomerase rejuvenation therapy for Alzheimer’s!

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

Bioviva a Seattle, WA, based biotech is ambitiously moving forward with gene therapy in people to mitigate the consequences of aging. They have not gone for the low hanging fruit either, they are being supported by Maximum Life Foundation to raise enough to run a clinical trial to try to cure Alzheimer’s! They are targeting the supporting Microglia cells in the brain to help regenerate them and hopefully reverse the effects of the disease. A worthy cause if ever I saw one and if it works could translate to other similar conditions like Parkinson’s and ALS. Lets hope they can get this vital work underway. This will then be the first example of regenerative medicine in a person that treats the dysfunction of aging.
