Learning a new photographic lesson
Sometimes you have to step back from how you normally do something to find a way to do that thing better. For a year or more, I’ve tended to set my camera shutterspeed to about 1/1000th of a second for bird photography. It’s a lower limit on capturing the rapid wing movements of small birds flitting from tree to tree and on and off the feeders. It works quite well, but the lens aperture then has to be as large as possible to compensate for the short length of time the sensor is exposed to light. Even then, if it’s not a bright day or I’m in woodland, the photo will not expose well and I have to bump...

Avian influenza (H5N8)
There are reminders in the news that other infectious diseases carry on, with reports of outbreaks of H5N8 avian influenza in wild birds and on farms.A few resources (more may follow):UK government advice on avian influenza, with updates on the latest situation.NHSA flu diary - blog kept by Michael Coston. There is a post from yesterday describing an outbreak in North Yorkshire, and one from the 11th November about other cases, so scan the posts. (Source: Browsing)

Nasal Endoscopy for Urgent and Complex ED Cases
Fiberoptics and endoscopy have changed the way we treat patients in the emergency department. Endoscopes are relatively easy to use, and can aid your diagnosis and treatment plan. Endoscopy may be useful in urgent cases, such as epistaxis, nasal foreign bodies, and ear debridement. It may also be helpful when dealing with more complicated presentations and critically ill patients, such as those with Ludwig's angina, epiglottis, tracheostomies, or those who need intubation.Fiberoptic tools are not just for surgeons and consultants. The endoscope has many uses in the emergency department, and we have a few tips and tricks...

Federal Aid Creates Central ‐Planning Power
This study argues that Congress should repeal all federal aid-to-state programs for many reasons, including that aid comes with costly strings attached that destroy local democracy.Richard Epstein and Mario Loyolanoted about aid programs: “When Americans vote in state and local elections, they think they are voting on state and local policies. But often they are just deciding which local officials get to implement the dictates of distant and insulated federal bureaucrats, whom even Congress can’t control.”I came across a table (p. 82) in New Jersey ’s budget that lists the $15 billion the state received in 2020 fro...

RSPB Ouse Fen
I’ve mentioned RSPB Ouse Fen a lot over the last few years, it’s a lovely quiet patch of flooded gravel pits, with some woodland, and reedbeds etc, not far from where we live. There are two ways to get to it, one is a lot closer and takes you into the reedbed side of the reserve, the far side is a longer drive and takes you through the more wooded areas. Both are nice, but I tend to favour the reedbed side.

INCREASING EPIDEMIC FREQUENCY
There’s mounting evidence that the rates of infectious disease outbreaks have been increasing in frequency over the past few years. Perhaps even in the past two decades.
From the period of the Spanish flu pandemic in 1918 to the HIV/AIDS epidemic around 1981, there were only six pandemics on record. Approximately one per decade.
However, since the SARS outbreak of 2002, there has been an increased frequency of outbreaks.
The records show that SARS was quickly followed by several recurring and new outbreaks. AVIAN flu, MARBURG virus, SWINE flu, MERS, and E...

A public health update on COVID-19 [PODCAST]
“Over the last 100 years, the U.S. has had to respond to five avian flu pandemics. The most severe was the 1918 avian influenza infecting 1/3 of the world ’s population and killing 650,000 Americans. It was also the last time wide-spread containment, mitigation, and isolation strategies were used in the U.S. Seldom mentioned about the […]Find jobs at Careers by KevinMD.com.

Silver-washed Fritillary butterfly
We visited Somerset in the summer of 2019 despite neither of us being fans of cider. We stayed on a beautiful part of the county’s north coast and did a lot of walking and visited a few nature reserves in the hope of seeing bird and insect species we might not commonly see in Cambridge where we live.
The Silver-washed Fritillary, Argynnis paphia, was one of the Lepidoptera I hoped to photograph. The species is widespread over the South West and Ireland (see here) and we saw several on flowers in the gardens of a cafe we visited after a five-mile walk. Spotted them only after I’d taken off my walking boots to c...

Red-footed Falcon
The red-footed falcon, Falco vespertinus, is usually found in eastern Europe and Asia but its numbers are falling because of habitat loss (what a surprise) and hunting (ditto). It is usually migrates south to Africa in the Winter. Occasionally vagrants are seen in western Europe in the summer.
Interestingly, one has been hanging around this last week or so at RSPB Fen Drayton, which is close to a village not far from us here in Cottenham. It’s apparently a first-year female so obviously not the same bird that has been seen on the same patch in previous years. We paid a visit to the reserve today and although light le...

Microfluidic Test for Viral Antibodies Takes Just 20 Minutes
Researchers at Hokkaido University in Japan have developed a microfluidic test that can detect antibodies against a viral infection. So far, the test has been optimized to detect avian flu, but could be adapted to detect antibodies against the virus causing COVID-19. The device can provide a result in as little as 20 minutes and requires only 2 microliters of serum to run.
Antibody
tests have been proposed as a way to determine how many people have been
exposed to COVID-19, and may help us to understand how far the virus has spread.
Given that many infected people are asymptomatic, they may never be recorded as
infected...

The Science of Infectious Disease Modeling
What Is Computer Modeling and How Does It Work?
Recent news headlines are awash in references to “modeling the spread” and “flattening the curve.” You may have wondered what exactly this means and how it applies to the COVID-19 pandemic. Infectious disease modeling is part of the larger field of computer modeling. This type of research uses computers to simulate and study the behavior of complex systems using mathematics, physics, and computer science. Each model contains many variables that characterize the system being studied. Simulation is done by adjusting each of the variables, alone or in combination, to ...

How One Model Simulated 2.2 Million U.S. Deaths from COVID-19
Alan ReynoldsWhen it came to dealing with an unexpected surge in infections and deaths from SARS-CoV-2 (the virus causing COVID-19 symptoms), federal and state policymakers understandably sought guidance from competing epidemiological computer models. On March 16, a 20-page report from Neil Ferguson ' s team at Imperial College London quickly gathered enormous attention by producing enormous death estimates. Dr. Ferguson had previously publicized almost equallysensational death estimates from mad cow disease, bird flu and swine flu.The New York Times quickly ran the hot news about this new COVID-19 estimate:The report, whi...
