That’s why researchers have developed high-tech glasses, called Amblyz, which can be programmed to treat lazy eye. The results of the first clinical trial assessing their efficacy were presented this week at the annual meeting of the American Academy of Ophthalmology.

Amblyz works because its lenses contain programmable LCDs. If a doctor suggested that a child wear a patch for two hours per day, for example, the lens over the lazy eye would go dark for a few seconds out of every 30 seconds during that time, effectively working as a patch. And since children with amblyopia often have other vision problems such as astigmatism or nearsightedness, Amblyz corrects their vision when not occluding it.

Where do we come from? There are many right answers to this question, and the one you get often depends on who you ask.

For example, an astrophysicist might say that the chemical components of our bodies were first forged in the nuclear fires of stars.

On the other hand, an evolutionary biologist might look at the similarities between our DNA and that of other primates’ and conclude we evolved from apes.

Memories are priceless, and the plight of dementia patients highlights how important they are to forming what makes us, well us. Now a new study has provided hope we may one day be able to restore lost memories.

A paper from researchers at MIT has demonstrated the reactivation of memories in amnesia patients with optogenetics — in which cell activity is controlled by bursts of light.

Opening up the blood-brain barrier to deliver drugs (credit: Focused Ultrasound Foundation)

The blood-brain barrier has been non-invasively opened in a human patient for the first time. A team at Sunnybrook Health Sciences Centre in Toronto used focused ultrasound to temporarily open the blood-brain barrier (BBB), allowing for effective delivery of chemotherapy into a patient’s malignant brain tumor.

Resetting Your Biological Clock: New Enzyme Found To Repair Telomeres.

The telomere caps on the end of your chromosomes unravel bit by bit with every cell division, and if they’re not repaired division eventually stops altogether. Cells like stem cells express special enzymes to lengthen these caps, and we’ve now found another one that does the job.

A key player in aging?

I had read about Singapore in genetic engineering way back in the 90’s. I think they were 1st or 2nd in making immortal skin cells at the time.

Singapore scientists have unravelled a mystery that could pave the way for turning back the clock on ageing.

A recent study led by Dr Ng Shyh Chang of the Genome Institute of Singapore at the Agency for Science, Technology and Research (A*Star) has found a gene in human egg cells that suppresses an enzyme causing cells to age.

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. Further information can be found on Prof. Zhang’s website at http://zlab.mit.edu.

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.
