Everything You Ever Wanted to Know About CRISPR
Posted by Gemechu Taye in categories: bioengineering, biotech/medical
Turns out, altering bacteria from within could be the solution to antibiotic resistance. In an ironic twist, researchers used viruses engineered with the CRISPR-Cas system to alter bacterial defense mechanisms and edit their genomes selectively in complex environments. Significantly, the novel approach may help address the pressing issue of antibiotic resistance.

Epidemiology of Glaucoma: The Past, Present, and Predictions for the Future
Posted by Liliana Alfair in categories: biotech/medical, genetics, health
Glaucoma impacts tens of millions of people globally, and is the second leading cause of blindness, after cataracts. Now, Purdue University researchers have developed smart contact lenses that may help save people’s sight.
Glaucoma is a multifactorial optic degenerative neuropathy characterized by the loss of retinal ganglion cells. It is a combination of vascular, genetic, anatomical, and immune factors. Glaucoma poses a significant public health concern as it is the second leading cause of blindness after cataracts, and this blindness is usually irreversible. It is estimated that 57.5 million people worldwide are affected by primary open-angle glaucoma (POAG). People over 60 years of age, family members of those already diagnosed with glaucoma, steroid users, diabetics, as well as those with high myopia, hypertension, central cornea thickness of.

Esper Hand is a “human-like” prosthetic arm that can be controlled by the mind

Video on prosthetic Esper hand.
New York-based engineering startup Esper Bionics has developed a flexible prosthetic mind-controlled hand that learns how to suggest the best grip faster than similar prosthetics.
Esper Bionics’ robotic arm is designed to be lighter and learn faster than many of the prosthetics currently available for amputees. The more the wearer uses the hand, the better and quicker it is to suggest the right grip.

Breathing may measurably modulate neural responses across brain, study finds
Posted by Saúl Morales Rodriguéz in categories: biotech/medical, engineering, neuroscience
Mental health practitioners and meditation gurus have long credited intentional breathing with the ability to induce inner calm, but scientists do not fully understand how the brain is involved in the process. Using functional magnetic resonance imaging (fMRI) and electrophysiology, researchers in the Penn State College of Engineering identified a potential link between respiration and neural activity changes in rats.
Their results were made available online ahead of publication in eLife. The researchers used simultaneous multi-modal techniques to clear the noise typically associated with brain imaging and pinpoint where breathing regulated neural activity.
“There are roughly a million papers published on fMRI—a non-invasive imaging technique that allows researchers to examine brain activity in real time,” said Nanyin Zhang, founding director of the Penn State Center for Neurotechnology in Mental Health Research and professor of biomedical engineering.

Study questions the medical privacy of forensic samples
Posted by Saúl Morales Rodriguéz in categories: biotech/medical, genetics, law enforcement
Watch any episode of “CSI,” and a character will use forensic DNA profiling to identify a criminal. A new study from San Francisco State University suggests that these forensic profiles may indirectly reveal medical information—perhaps even those of crime victims—contrary to what the legal field has believed for nearly 30 years. The findings, now published in the Proceedings of the National Academy of Sciences, could have ethical and legal implications.
“The central assumption when choosing those [forensic] markers was that there wouldn’t be any information about the individuals whatsoever aside from identification. Our paper challenges that assumption,” said first author Mayra Bañuelos, who started working on the project as a San Francisco State undergraduate and is now a Ph.D. student at Brown University.

Lab discovers new pathway for antimicrobial peptides
Posted by Genevieve Klien in category: biotech/medical
Researchers in the Princeton University Department of Chemistry have discovered a new multi-step pathway through which bacteria found in the mammalian gut produce antimicrobial peptides.
The newly identified biosynthetic pathway transforms a biologically inert peptide into structurally complex antibiotics, which they call enteropeptins. Enteropeptins are a class of ribosomally synthesized peptide natural products, referred to as RiPPs.
The core structure of these products is synthesized by the ribosome, which is limited to the 20 canonical amino acids. The Mo Lab discovered and characterized new metalloenzymes capable of converting arginine, a canonical amino acid, into N-methylornithine, a noncanonical amino acid, within enteropeptin.
