Ventilation
Issues
A recent archived version of the CDC’s web
page made no mention of airborne transmission, emphasizing that the main way
the virus spreads is through close contact among people who are within six feet
of each other, through respiratory droplets emitted by coughing, sneezing, and
speaking. It acknowledged that the virus may spread in other ways, including on
contaminated surfaces.
The CDC’s updated site includes a section acknowledging
that virus particles also sometimes spread through the air, particularly in
enclosed spaces with poor ventilation. Scientists believe that in these cases,
airborne virus particles emitted “became concentrated enough to spread the
virus to other people,” including sometimes shortly after the infectious person
left.
The transmissions sometimes occurred when the infected
person was breathing heavily, while singing or exercising, the agency said.
Linsey Marr, an expert on the airborne transmission of
viruses at Virginia Tech, in a tweet called the update “an
accurate, sorely-needed update acknowledging airborne spread and importance of
masks at all times around others and of ventilation.”
In an open letter in July, 239
scientists urged the World Health Organization to recognize the potential for
airborne spread. One study of a meat plant suggested that under certain conditions
the virus can travel 26 feet.
Summary:
Researchers have developed a new type of multiplexed test (a test that combines
multiple kinds of data) with a low-cost sensor that may enable the at-home
diagnosis of a COVID-19 infection through rapid analysis of small volumes of
saliva or blood, without the involvement of a medical professional, in less
than 10 minutes.
One feature of the COVID-19 virus that makes it so difficult to contain
is that it can be easily spread to others by a person who has yet to show any
signs of infection. The carrier of the virus might feel perfectly well and go
about their daily business -- taking the virus with them to work, to the home
of a family member, or to public gatherings.
A crucial part of the global effort to stem the spread of the pandemic,
therefore, is the development of tests that can rapidly identify infections in
people who are not yet symptomatic.
Now, Caltech researchers have developed a new type of multiplexed test
(a test that combines multiple kinds of data) with a low-cost sensor that may
enable the at-home diagnosis of a COVID infection through rapid analysis of
small volumes of saliva or blood, without the involvement of a medical
professional, in less than 10 minutes.
The research was conducted in the lab of Wei Gao, assistant professor in
the Andrew and Peggy Cherng department of medical engineering. Previously, Gao
and his team have developed wireless sensors that can monitor conditions such
as gout, as well as stress levels, through the detection of extremely low
levels of specific compounds in blood, saliva, or sweat.
Gao's sensors are made of graphene, a sheet-like form of carbon. A
plastic sheet etched with a laser generates a 3D graphene structure with tiny
pores. Those pores create a large amount of surface area on the sensor, which
makes it sensitive enough to detect, with high accuracy, compounds that are
only present in very small amounts. In this sensor, the graphene structures are
coupled with antibodies, immune system molecules that are sensitive to specific
proteins, like those on the surface of a COVID virus, for example.
Previous versions of the sensor were impregnated with antibodies for the
hormone cortisol, which is associated with stress, and uric acid, which at high
concentrations causes gout. The new version of the sensor, which Gao has named
SARS-CoV-2 RapidPlex, contains antibodies and proteins that allow it to detect
the presence of the virus itself; antibodies created by the body to fight the
virus; and chemical markers of inflammation, which indicate the severity of the
COVID-19 infection.
"This is the only telemedicine platform I've seen that can give
information about the infection in three types of data with a single
sensor," Gao says. "In as little as a few minutes, we can
simultaneously check these levels, so we get a full picture about the
infection, including early infection, immunity, and severity."
Established COVID-testing technologies usually take hours or even days
to produce results. Those technologies also require expensive, complicated
equipment, whereas Gao's system is simple and compact.
It may provide a “temporary buffer against getting another
virus” while the body is all “revved up” to fight it

Researchers are looking at whether the common cold could
offer some protection against contracting Covid-19.
A recent study by scientists at Yale University found that
rhinovirus – the most frequent cause of common cold – could jump-start the
body’s antiviral defences, providing protection against the flu.
They discovered that the presence of rhinovirus triggered
production of the antiviral agent interferon, which is part of the early immune
system response to invasion of pathogens.
The researchers are now looking at whether introduction of
the cold virus before infection by the Covid-19 virus offers a similar type of
protection.
Dr Ellen Foxman, of the Yale School of Medicine, told the
PA news agency: “The common cold virus triggers the normal antiviral defences
of these cells that form the lining of the airway.
“So the cells that form the lining of the airway is where
all these viruses need to go to grow.
“That includes flu, common cold, Covid-19 – basically all
the viruses that you get by breathing them in, they all grow in this tissue
that forms the lining of your airway.”
She added: “This response, the interferon response, which
is this general defence mechanism against all viruses, we know that response
does work against Covid-19.
“If you do the experiment in a lab, you can apply this
chemical – interferon – to cells, then you can block the virus that causes
Covid-19 as well.
“So it’s possible that we’ll see the same thing, but we’re
just beginning to do the experiments.
“Sometimes you see unexpected things happening so you have
to just do the experiment and see what the result is and that that’s just a
work in progress at the moment.”
Dr Foxman said she thought interferon-based immunity lasted
about a week, maybe up to two, adding that it did not prevent infection
forever.
But she explained it may provide a “temporary buffer
against getting another virus” while the body is all “revved up” to fight it.
However, the expert said while she was sure this could be
applied to flu, Covid-19 is unpredictable.

Sensor with 100,000 times higher
sensitivity could bolster thermal imaging
Better detection
of microwave radiation will improve thermal imaging, electronic warfare, radio

Summary:
New research developed a new microwave radiation sensor with 100,000 times
higher sensitivity than currently available commercial sensors. Researchers
said better detection of microwave radiation will enable improved thermal
imaging, electronic warfare, radio communications and radar.
Army-funded research developed a new microwave radiation sensor with
100,000 times higher sensitivity than currently available commercial sensors.
Researchers said better detection of microwave radiation will enable improved
thermal imaging, electronic warfare, radio communications and radar.
Researchers published their study in the peer-reviewed journal Nature.
The team includes scientists from Harvard University, The Institute of Photonic
Sciences, Massachusetts Institute of Technology, Pohang University of Science
and Technology, and Raytheon BBN Technologies. The Army, in part, funded the
work to fabricate this bolometer by exploiting the giant thermal response of graphene
to microwave radiation.
"The microwave bolometer developed under this project is so
sensitive that it is capable of detecting a single microwave photon, which is
the smallest amount of energy in nature," said Dr. Joe Qiu, program
manager for solid-state electronics and electromagnetics, Army Research Office,
an element of the U.S. Army Combat Capabilities Development Command's Army
Research Laboratory. "This technology will potentially enable new
capabilities for applications such as quantum sensing and radar, and ensure the
U.S. Army maintains spectral dominance in the foreseeable future."
The graphene bolometer sensor detects electromagnetic radiation by
measuring the temperature rise as the photons are absorbed into the sensor.
Graphene is a two dimensional, one-atom layer thick material. The researchers
achieved a high bolometer sensitivity by incorporating graphene in the
microwave antenna.
A key innovation in this advancement is to measure the temperature rise
by superconducting Josephson junction while maintaining a high microwave
radiation coupling into the graphene through an antenna, researchers said. The
coupling efficiency is essential in a high sensitivity detection because
"every precious photon counts."
A Josephson junction is a quantum mechanical device which is made of two
superconducting electrodes separated by a barrier (thin insulating tunnel
barrier, normal metal, semiconductor, ferromagnet, etc.)
In addition to being thin, the electrons in graphene are also in a very
special band structure in which the valence and conduction bands meet at only
one point, known as Dirac point.
"The density of states vanishes there so that when the electrons
receive the photon energy, the temperature rise is high while the heat leakage
is small," said Dr. Kin Chung Fong, Raytheon BBN Technologies.
With increased sensitivity of bolometer detectors, this research has
found a new pathway to improve the performance of systems detecting
electromagnetic signal such as radar, night vision, LIDAR (Light Detection and
Ranging), and communication. It could also enable new applications such as
quantum information science, thermal imaging as well as the search of dark
matter.
The part of the research conducted at MIT included work from the
Institute for Soldier Nanotechnologies. The U.S. Army established the institute
in 2002 as an interdisciplinary research center to dramatically improve
protection, survivability and mission capabilities of the Soldier and of
Soldier-supporting platforms and systems.
Great fire of
Newcastle and Gateshead October 6, 1854.
The
great fire of Gateshead and Newcastle was a tragic and spectacular
series of events starting on Friday 6 October 1854, in which a substantial
amount of property in the two North
East of England towns was destroyed in a series of fires and an
explosion which
killed 53 and injured hundreds. There is only one building still extant on the
Newcastle Quayside which predated the fire.[1]
----Such a large fire
naturally attracted many spectators, who occupied every spot on the bridges, boats,
quayside and surrounding buildings. The fire spread to a wooden staith or jetty used in former
times for loading coal,
which for a time shared with the warehouse the attention of the thronging
multitude.
A slight concussion warned the crowd that there was
something more perilous than sulphur alone in the burning pile. A second slight
explosion
did not warn the firemen and surrounding crowds. A third passed unheeded even.
After a few minutes, the final explosion occurred. The
vaults of the warehouse were burst open with a tremendous and terrific
explosion, heard 20 miles (32 km) away. Vessels on the river lifted as if
lashed by a sudden storm. The old bridge shook, and the new quivered. Massive
walls were crumbled into heaps, houses tumbled into ruins. The venerable parish
church, on the hill, was shattered to a wreck. Gravestones
were broken and uplifted. The hands on the dial of its clock stood at ten
minutes past three.
Thick black smoke rose as a "pillar of cloud";
temporarily all was silent; and then the scene was lit by falling burning
debris from the warehouse, the noise of falling dwellings and then the cries of
the injured.
