Multistep Lateral Flow Devices Perform Advanced Assays
Researchers at Georgia Tech have developed a lateral flow test platform that can perform advanced assays that would otherwise require a laboratory. By controlling the flow of liquid through the lateral flow test, the research team designed it so that it can perform advanced multistep assays that do not require sophisticated lab equipment and significant periods of time. So far, they have designed advanced dipstick tests that can detect both COVID-19 and influenza simultaneously, and others that can perform immunoassays to detect Zika virus, HIV, hepatitis B virus, or malaria.

Wuhan spiny eel influenza virus
Influenza B viruses, unlike influenza A viruses, do not cause pandemics. There are many non-human animal reservoirs of influenza A viruses which provide gene segments that go towards making reassortant viruses that can infect humans. Influenza B viruses do not appear to have an animal reservoir other than humans – they have been isolated from […] (Source: virology blog)

Physicians are human and grief is as much a part of the human experience as love
Since the first documented COVID death in the U.S. in February 2020, over 726,000 Americans have died. The number of deaths eclipses the death toll of any other American tragedy, whether war or the Spanish influenza epidemic of 1918, and health care providers have been involved with the care of many people who have died.Read more …Physicians are human and grief is as much a part of the human experience as love originally appeared inKevinMD.com.

Trial By Error: BBC ’ s Problematic Coverage of New Long COVID Study
By David Tuller, DrPH Since the start of the coronavirus pandemic, suggesting an equivalence between COVID-19 and influenza has been a consistent approach among those seeking to downplay the current situation. So it’s not surprising to see something similar happen with comparisons between Long COVID and the delayed recovery some people experience after an acute […] (Source: virology blog)

Relative risk perception and public investment
Motor vehicles are not quite in the top 10 causes of death in the U.S.The way the CDC categorizes causes of death, unintentional injuries are number 3, about 173,000 deaths per year, and motor vehicle-related injuries constitute about 1/3 of those. If you were to extract those 40,000+ motor vehicle deaths they would probably be at about #11. (This data is from 2019, and for 2020 Covid has undoubtedly bumped up cause number 9, " influenza and pneumonia, from 9 to 3 making unintentional injuries number 4, but we can hope this is temporary.) However, unlike the other leading causes of death, which disproportionatel...

Staying Safe From Sepsis

Your immune system is on patrol every day. It protects your body from bacteria, viruses, and other germs. But if something goes wrong, it can also cause big problems.

Gain of function research explained
The term ‘gain of function’ is perhaps one of the most misunderstood in the scientific lexicon. I would like to explain what the phrase means from the perspective of a scientist who has done gain of function research for the past 40 years. Gain of function (GoF) research gives an organism a new property or […] (Source: virology blog)

Selfish Much?
By KIM BELLARD
In a week where we’ve seen the bungled Afghan withdrawal, had Texas show us its contempt for all sorts of rights, watched wildfires ravage the west and Ida wreak havoc on a third of the country, and, of course, witnessed COVID-19 continue its resurgence, I managed to find an article that depressed me further. Thank you, Aaron Carroll.
Dr. Carroll – pediatrician, long-time contributor to The New York Times, and now Chief Health Officer of I.U. Health — wrote a startling piece in The Atlantic: We’ve Never Protected the Vulnerable. He looks at the resistance to public health measur...

Here Come the Workplace Vaccine Religious Exemption Battles
Walter OlsonCompanies like Wal ‐Mart, United Air Lines, and Tyson Foods have announced plans to require part or all of their workforce to be vaccinated against COVID-19. Many employee claims for religious exemptions are likely to follow. How are they likely to fare as a legal matter?InApril I wrote:Title VII, the federal employment discrimination law, forces an employer to accommodate employees ’ religious beliefs when it can do so without cost. For that reason, employees with religious objections to vaccination can ask employers to exempt them, and employers must at least consider the request. “Consider...

Age-Related Dysfunction in Cellular Metabolism Substantially Impacts the Immune System
Most of what to my eyes are less promising lines of research into the treatment of aging are focused on manipulation of cellular metabolism. These approaches, such as targeting the mTOR pathway, largely derive from the study of calorie restriction and the cellular response to stress that is brought on by lack of nutrients. Calorie restriction extends average and maximum life span considerably in short-lived species, up to 40% in mice, for example. It increases the efficiency of cellular maintenance processes and makes cells more frugal in other ways. The impact of aging is slowed, as molecular damage accumulates less rapid...

COVID ’s lab leak theory obscures zoonosis and progression
Even as COVID-19 is found in apes, big cats, minks, domestic cats, other small mammals, and now in U.S. deer, some don ’t want to let go of the insultingly simplistic “lab leak” theory.
