Carbon-coated iron catalyst structure could lead to more-active fuel cells

Posted by in categories: nanotechnology, particle physics, transportation

Abstract: Fuel cells have long held promise as power sources, but low efficiency has created obstacles to realizing that promise. Researchers at the University of Illinois and collaborators have identified the active form of an iron-containing catalyst for the trickiest part of the process: reducing oxygen gas, which has two oxygen atoms, so that it can break apart and combine with ionized hydrogen to make water. The finding could help researchers refine better catalysts, making fuel cells a more energy- and cost-efficient option for powering vehicles and other applications.

Led by U. of I. chemistry professor Andrew Gewirth, the researchers published their work in the journal Nature Communications.

Iron-based catalysts for oxygen reduction are an abundant, inexpensive alternative to catalysts containing precious metals, which are expensive and can degrade. However, the process for making iron-containing catalysts yields a mixture of different compounds containing iron, nitrogen and carbon. Since the various compounds are difficult to separate, exactly which form or forms behave as the active catalyst has remained a mystery to researchers. This has made it difficult to refine or improve the catalyst.

CRISPR: What Does Gene Editing Mean for the Future of Primal Living?

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

By now, you’ve no doubt heard of CRISPR, the latest gene-editing tool sweeping research labs across the globe. It was first discovered in certain strains of bacteria, who use it as an important weapon against dangerous viruses. In bacteria, CRISPR identifies a virus that poses a threat, records the virus’ genetic data and imprints it onto RNA molecules. An immune enzyme called Cas9 grabs one of the RNA molecules and goes exploring. When Cas9 encounters a virus that matches the data on the RNA molecule, it latches on and slices the virus in half to prevent it from replicating and posing any threat.

Researchers have co-opted the CRISPR/Cas9 mechanism to edit genes. Instead of copying dangerous viral DNA sequences onto the RNA molecules, they can copy over any sequence they want to edit. And instead of Cas9 destroying viruses, it makes precise cuts and removes specific bits of genetic data from the designated sequence. This allows researchers to target and edit specific gene sequences with genetic data of their choosing.

Dark Web Criminals Supplying Forged Diplomas & Certifications

Posted by in categories: biotech/medical, computing, education, employment, internet

And, we all have heard all of the horrorr stories of a botch surgery or treatment performed by a MD who was a fraud. Well, our friends on the Dark Web are at work again in supplying anyone willing to pay fake diplomas & certifications. The challenge is how do companies and agencies validate? Something to ponder as we all know hackers can also forge educational records as well.


Criminals on the Dark Web (a lawless, unregulated part of the Internet) are supplying fake diplomas and employment certifications to anyone with a few hundred bucks.

According to Israeli threat intelligence firm Sixgill, people are even hiring hackers to penetrate university computer systems to alter grades.

A tight squeeze for electrons: Quantum effects observed in ‘one-dimensional’ wires

Posted by in categories: computing, particle physics, quantum physics

Condensing electrons into Quantum Wires to advance QC on multiple devices as well as other areas of technology.


Researchers have observed quantum effects in electrons by squeezing them into one-dimensional ‘quantum wires’ and observing the interactions between them. The results could be used to aid in the development of quantum technologies, including quantum computing.

Scientists have controlled electrons by packing them so tightly that they start to display quantum effects, using an extension of the technology currently used to make computer processors. The technique, reported in the journal Nature Communications, has uncovered properties of quantum matter that could pave a way to new quantum technologies.

Programmable Biology Has Begun

Posted by in categories: bioengineering, biotech/medical, genetics, life extension, singularity

Scientists have completed reprogramming DNA on the largest scale ever, making the concept of superhumans a reality while advancing Singularity.


Cloned embryo.

Most of us like the idea of superpowers. Though we may never have the strength of Superman, we could be made stronger, faster, and even better-looking, with total control over our genome, or genetic makeup. What about becoming disease-resistant, weight gain resistant, and even slowing down the aging process? This might be possible in decades to come, as geneticists are now getting ever closer to, not just removing and replacing genes, but rewriting entire genomes. It sounds like the realm of science fiction. Yet, consider that geneticists at Harvard recently recoded the genome of a synthetic E. coli bacteria. Prof. George Church and colleagues conducted the study.
