Silver-Silica and Antibiotic Combination Lethal to Germs

Re-Blogged From The Silver Institute

By coating silver-silica nanoparticles with an antibiotic,
Brazilian scientists have found a more powerful way to kill
drug-resistant bacteria.
Normally, silica compounds – silica is the mineral quartz
– are toxic when inhaled, causing the disease silicosis in
which the particles scar the lungs making it difficult to
breathe. Silicosis often is seen in foundry workers, glass
makers and those who work in rock quarries.
However, when the research team wrapped the antibiotic
ampicillin around silver-silica it renders it harmless allowing
both the silver ions and antibiotic to kill germs without
harming human cells.
The combination has not been tested on people, but
laboratory results show that it overcame a strain of
E. coli that was resistant to antibiotic drugs alone.
“There are commercial drugs that contain nanoparticles,
which typically serve to coat the active ingredient and
extend its lifetime inside the organism.
Our strategy is different. We decorate the surface of the nanoparticles with
certain chemical groups that direct them to the site where
they’re designed to act, so they’re highly selective,” said
Mateus Borba Cardoso, lead study author and a researcher
at Brazil’s National Energy & Materials Research Center
(CNPEM) in an interview in
“We used molecular modeling to find out which part of
the ampicillin molecule interacted most with the bacterial
membrane,” he added. “We then arranged all the molecules
of the drug so that this key part was facing outward from the
nanoparticle, increasing the likelihood of interaction with
the pathogen.”
The silver-silica/antibiotic treatment has a drawback. Silver-
silica is inorganic and humans don’t metalize it, so it could
build up in the body. Cardoso said that his group is studying
this issue to learn whether it presents a danger or not. He
plans to do animal testing.
One possibility is to developa nanoparticle that can be excreted through urine. He
suggests, though, that for patients for whom no other cure
exists for their bacterial infection, the silver-silica/antibiotic
mixture offers hope where none is available.

Moody’s: State Pension Liabilities Hit $1.3 Trillion

From Thomson Reuters – Re-Blogged From Newsmax

U.S. state unfunded pension liabilities hit $1.3 trillion in fiscal 2016, a $56 billion or 4.5 percent increase over the previous fiscal year, Moody’s Investors Service reported.

 The credit rating agency attributed the higher adjusted net pension liability for the 50 states to underperforming investment returns, low interest rates and insufficient contributions to retirement systems for government workers.

In Praise Of The Whistleblowers

By Charles Thorngren – Re-Blogged From

Whistleblowers run a two-pronged battle – on the one hand they are lauded for their honesty in exposing wrongdoing in the fields in which they are involved – on the other, they are hated and despised for their actions by those who want to cover misdeeds, or preserve the status quo.

The world of finance has a long history of such characters – some, like Michael Lewis, the ex-bond salesman from Wall Street, who worked for Salomon Brothers in the 1980s and exposed the work practices and ethos which subsumed banks and trading houses – have made their fortunes by such whistleblowing.

Others, like Hervé Falciani, an employee of HSBC’s Swiss private bank, who opened the door onto the bank’s money laundering techniques, and gave details of the hidden accounts of 130,000 wealthy individuals to the tax authorities, was jailed for 5 years for his activities.

China to Ban Gasoline Powered Passenger Cars (Maybe)

The purveyors of greenschist (a geologically inspired euphemism for green sh!t) seem to have an obsession with a phrase that they clearly do not comprehend: Tipping point.

Electric Cars Reach a Tipping Point

David Fickling

Sep 10, 2017

Say goodbye to gasoline. The world’s slow drift toward electric cars is about to enter full flood.

China, one-third of the world’s car market, is working on a timetable to end sales of fossil-fuel-based vehicles, the country’s vice minister of industry and information technology, Xin Guobin, told an industry forum in Tianjin on Saturday. That would probably see the country join Norway, France and the U.K. in switching to a wholly electric fleet within the lifetime of most current drivers.

  • President Maduro ‘ Venezuela will create a basket of currencies to free us from the dollar,”
  • Oil traders ordered to stop accepting U.S. dollar in exchange for crude oil
  • Order comes following calls from Russia and China to find alternatives to current reserve system
  • U.S. Dollar accounts for two-thirds of global trade
  • Venezuela has over ten-times more oil than United States
  • Super powers are gradually turning to gold to avoid using world’s main reserve currency
  • Are we seeing the beginning of the end for the U.S. dollar?

Writing with an Electron Beam in Silver for the First Time

Re-Blogged From The Silver Institute
If you want to deposit extremely fine features onto another material, nothing
beats Electron-Beam-Induced Deposition or EBID. Although most people
haven’t heard of this process, it’s quite common in sophisticated manufacturing
products such as micro-miniature electronic components and equipment.
The process uses a scanning electron microscope to shoot a beam of electrons
that deposit or ‘write’ nanoparticles of gold, platinum, copper and other metals
except for silver — until now.

The Making of a Climate Skeptic – at University

Foreword by Anthony Watts -Re-Blogged From
This essay is written by a student at the University of Wyoming, who finds herself in the middle of a set of circumstances that are pushing her further into the realm of being a climate skeptic. It is an eye-opening read. I have verified the identity of the student, but per her request (due to the backlash she fears) I am allowing her to write under the pen name of “Clair Masters”

Guest essay by Clair Masters

The class was languid, most kids were on their phones, or surfing Facebook on their laptops. I sat with my notebook open in front of me, empty except for the lecture title at the top of the page. The professor put a slide up on the projector showing a chart relating CO2 and temperature over the course of a few million years, the one we’ve all seen by now. The CO2 curve lags after the Temperature one, and anyone’s first reading of the chart would probably be that temperature is driving the CO2 changes, not the other way around, if there is any trend at all. I perked up slightly, it was new for a professor to show alternate data, and looked around expectantly at other students, waiting for some kind of reaction—confusion, frowns, anything to show they’re seeing something that fights what we’ve been told since elementary school. I saw a few yawns, dull stares, people on their phones, though one loud girl who was a religious global warming fanatic was glaring at the slide, slouching in her seat so her hand could pet her (dubiously trained) service dog.
