This animation depicts the CRISPR-Cas9 method for genome editing – a powerful new technology with many applications in biomedical research, including the potential to treat human genetic disease. Feng Zhang, a leader in the development of this technology, is a faculty member at MIT, an investigator at the McGovern Institute for Brain Research, and a core member of the Broad Institute.

Treating the brain often requires invasive surgery, but a new technique involving ultrasound and air bubbles has now shown promise at delivering drugs through the blood-brain barrier.

One of the biggest challenges of medicating brain tumours is actually getting drugs into the organ. Your brain is well protected from invasion by untoward substances or life forms, and this protection limits what will enter from the bloodstream. There have been previous efforts to open up the barrier, but they often involve a surgical approach that is far from ideal.

New article for Vice Motherboard on why society should support legalization of all drugs–and a short video of the Immortality Bus in Arkansas talking to marijuana supporters (a state where it’s totally illegal):

Sugars may taste divine, but they’re also highly reactive molecules that progressively stiffen your body in a process called glycation. Scientists have now synthesised the primary molecule formed in glycation for the first time, leading to hope that drugs can be designed to break them apart.

What is glycation?

In our bodies sugars continuously react with proteins in an unregulated manner in a process known as glycation. This leads to the formation of abnormal chemical modifications of the protein which may impair its normal function. These sugar-modifications are collectively known as advanced glycation end products (AGEs) and can be subdivided in two main categories. First are the modifications that affect a single amino acid. The second category consists of modifications that link two amino acids together in a structure called a crosslink.

Pluripotent cells are great, but they can be difficult to steer into growing the way you want. Now scientists have found a new way to create 3D-printed ‘building blocks’ of embryonic stem cells (ESCs), which could be used for growing micro-organs, performing tissue regeneration experiments, testing medication and other biology research purposes.

While bioprinting with ESCs is not entirely new, until recently researchers have only managed to produce two-dimensional sheets of cells. Now a team of scientists from Tsingua University in China and Drexel University in Philadelphia have published a study in Biofabrication, introducing a novel technique for printing a grid-like 3D structure laden with stem cells.

In normal biological conditions ESCs naturally tend to cluster together into spherical ‘embryoid bodies’ – clumps of pluripotent cells which can go on to develop into any type of cell or tissue in the human body.

A pioneering gene editing therapy has shown remarkable success in a unique trial at Great Ormond Street, paving the way for a wave of gene editing trials.

A world first

Not long ago, 1 year old Layla Richards had an incurable form of leukaemia and the prognosis wasn’t looking good. After a determined search for a cure, Layla underwent an experimental therapy in which ‘designer’ immune cells were implanted that would destroy and replace her own ailing immune system.

Steve Williams couldn’t breathe. The former athlete had cardiomyopathy, which occasionally choked his lungs with fluid, making him gasp for air. But this felt different; Williams felt like he was dying. He was raced to an Orange County hospital, and shortly after checking in, his heart stopped. For 30 minutes, ER workers compressed his chest in an attempt to revive him. At one point, his wife Mary remembers being called into his room to say goodbye to her husband of 24 years. It seemed Williams was a dead man.

Incredibly, doctors rebooted Williams’ heart — but for three days, he was in an induced coma, his body packed in ice to minimize brain damage. When he woke up, his mental facilities were intact, but his body was ravaged. His liver was congested, fluid reappeared in his lungs, and his heart’s right and left ventricles were practically destroyed, making it hard for blood to circulate throughout his body. Without a heart transplant, he would soon die.
