Neurosurgeons using lasers to treat brain cancer have discovered that the technique breaks down the blood-brain barrier, a finding that could lead to new treatment options for patients with the deadly disease.

The blood-brain barrier is sort of a natural “security system” that shields the brain from toxins in the blood but also blocks potentially helpful drugs such as those used in chemotherapy.

“We were able to show that this blood-brain barrier is broken down for about four weeks after you do this laser therapy,” said Dr. Eric Leuthardt, a professor of neurosurgery at Washington University in St. Louis. “So not only are you killing the tumor, you are actually opening up a window of opportunity to deliver various drugs and chemicals and therapies that could otherwise not get there.”

No longer in the movies.

Specific regions of the brain are specialized in recognizing bodies of animals and human beings. By measuring the electrical activity per cell, scientists from KU Leuven, Belgium, and the University of Glasgow have shown that the individual brain cells in these areas do different things. Their response to specific contours or body shapes is very selective.

Facial recognition has already been the subject of much research. But what happens when we cannot recognize an animal or a human being on the basis of a face, but only have other body parts to go on? The mechanism behind this recognition process is uncharted territory for neuroscientists, says Professor Rufin Vogels of the KU Leuven Laboratory for Neuro- and Psychophysiology.

“Previous research in monkeys has shown that small areas in the temporal lobes — the parts of the brain near the temples — are activated when the monkeys look at bodies instead of objects or faces. Brain scans tell us that these regions of the brain correspond to the ones activated in human beings. But that only tells us which regions are active, not which information about bodies is passed on by their cells.”

Very cool!

As we age, tiny blood vessels in the brain stiffen and sometimes rupture, causing “microbleeds.” This damage has been associated with neurodegenerative diseases and cognitive decline, but whether the brain can naturally repair itself beyond growing new blood-vessel tissue has been unknown. A zebrafish study published on May 3 in Immunity describes for the first time how white blood cells called macrophages can grab the broken ends of a blood vessel and stick them back together.

“Microbleeding occurs very often in the human brain, particularly in elderly people,” says Lingfei Luo, a developmental geneticist at Southwest University in China. “We believe that this macrophage behavior is the major cellular mechanism to repair ruptures of blood vessels and avoid microbleeding in the brain.”

To simulate a human brain microbleed, Luo and his colleagues shot lasers into the brains of live zebrafish to rupture small blood vessels, creating a clean split in the tissue with two broken ends. Then, the researchers used a specialized microscope to watch what happened next.

All I can say is WOW!!!! US Security Intelligence awards contract to University of Sydney who is also partnering with China. Also, this should send a huge message to the university in the US that Sydney is kicking it.

The US office of the director of national intelligence has awarded a mutlimillion dollar research grant to an international consortium that includes a quantum science laboratory at the University of Sydney.

A groundbreaking trial to see if it is possible to regenerate the brains of dead people, has won approval from health watchdogs.

A biotech company in the US has been granted ethical permission to recruit 20 patients who have been declared clinically dead from a traumatic brain injury, to test whether parts of their central nervous system can be brought back to life.

Scientists will use a combination of therapies, which include injecting the brain with stem cells and a cocktail of peptides, as well as deploying lasers and nerve stimulation techniques which have been shown to bring patients out of comas.

In this new short written and directed by the Brothers Lynch, a pioneering mind transfer procedure offers a quadriplegic soldier the opportunity to start a new life. Naturally, things don’t go quite as planned.

This teaser short, titled Trial, is a miniature version of an intended full-length sci-fi action thriller called Residual. Backed by Creative England, the new short is meant to help with the financing of the proposed feature.

Trial was produced by Ed Barratt of Hook Pictures, and it stars Tom Cullen, Ana Ularu and Joseph Mawle. Go here to learn more.
