As brain maps proliferate, scientists aim to sync them up

Posted by in categories: biotech/medical, neuroscience

Brain maps seem to come out in rapid succession these days. They take various forms: a map for word concepts, a map of individual cells’ activity, a map based on the organ’s physical contours.

What they share in common is the aspiration to take the lumpy mass of the brain and categorize it, somehow, into useable areas — not unlike the textbook brain images with their colored denotations of “occipital lobe” and “frontal cortex.”

But these maps often come along with a problem: They may not sync up with the other maps. Now a group of scientists have managed to sync up two of the most commonly used types of brain maps — for gene expression and brain structure — and they’re releasing their methods to any and all in the scientific community.

A First: Israeli Scientists “Have Used the Human Mind to Control Nano Robots Inside a Living Creature”

Posted by in categories: biotech/medical, computing, information science, neuroscience, robotics/AI

Researchers at Bar Ilan University and the Interdisciplinary Center in Herzliya, both in Israel, have developed new technology that allows tiny bots to release drugs into the body controlled by human thought alone. The test involved a man using his thoughts to activate nano robots inside a cockroach.

The bots have been built using a DNA origami structure with hollow shell-like components, and they come with a “gate” that can be opened and shut with the help of iron oxide nanoparticles that act as a “lock” – which can be prized open using electromagnetic energy.

The Israeli team believe the bots could help in controlled release of drugs over time. Led by Dr Ido Bachelet of Bar Ilan University, scientists demonstrated how to control this process with human brainwaves. Using a computer algorithm, they trained the system to detect when a person’s brain was under strain from doing mental arithmetic. The team then placed a fluorescent drug in the bots and injected them into various cockroaches that were placed inside an electromagnetic coil.

Scientists unlock genetic code controlling limb regeneration

Posted by in categories: biotech/medical, genetics

Many lower organisms retain the miraculous ability to regenerate form and function of almost any tissue after injury. Humans share many of our genes with these organisms, but our capacity for regeneration is limited. Scientists at the MDI Biological Laboratory in Bar Harbor, Maine, are studying the genetics of these organisms to find out how regenerative mechanisms might be activated in humans.

The ability of animals to regenerate body parts has fascinated scientists since the time of Aristotle. But until the advent of sophisticated tools for genetic and computational analysis, scientists had no way of studying the genetic machinery that enables regeneration. Using such tools, scientists at the MDI Biological Laboratory have identified genetic regulators governing regeneration that are common across species.

In a paper published in the journal PLOS ONE, MDI Biological Laboratory scientistsBenjamin L. King, Ph.D., and Voot P. Yin, Ph.D., identified these common genetic regulators in three regenerative species: the zebrafish, a common aquarium fish originally from India; the axolotl, a salamander native to the lakes of Mexico; and the bichir, a ray-finned fish from Africa.

If You Edit Genes Using CRISPR, Can You Undo the Effects?

Posted by in categories: bioengineering, biotech/medical, genetics

#CRISPR can be used to alter the genes of not only one organism, but an entire species, through a method of inheritance known as a gene drive. But what happens if something goes awry?

Faces of murderers could be recreated from DNA left at crime scenes after science breakthrough

Posted by in categories: biotech/medical, genetics, science

The faces of murderers or rapists could be ‘recreated’ from DNA left at the scene of the crime, according to new research.

Scientists have identified the genes that shape the extraordinary variation in the human face.

Many features, such as nose size and face width, stem from specific mutations, say researchers.

Scientists at Emory University School of Medicine have found that the dietary supplement alpha lipoic acid (ALA) can stimulate telomerase, the enzyme that lengthens telomeres, with positive effects in a mouse model of atherosclerosis.

In human cells, shortened telomeres, the protective caps at the ends of chromosomes, are a sign of aging and also contribute to aging.
