Sep. 18, 2021 -- A hospital system in Arkansas is requiring employees to confirm that they won’t use common medications — such as Tylenol, Tums, and Preparation H — to receive a religious exemption for the COVID-19 vaccine, according to Becker’s Hospital Review.
The Conway Regional Health System has required the flu shot annually as part of employment, but managers saw a spike in vaccine exemption requests for the COVID-19 vaccine.
“This was significantly disproportionate to what we’ve seen with the influenza vaccine,” Matt Troup, president and CEO of the health system, told Becker’s.
The majority of requests cited the use of fetal cell lines in the development of vaccines as part of the religious exemption. The practice uses cells grown in labs to test many new vaccines and drugs, including common antacids and cold medications.
“Thus, we provided a religious attestation form for those individuals requesting a religious exemption,” Troup said.
The hospital’s form includes a list of 30 common medications that used fetal cell lines during research and development. The list includes acetaminophen, albuterol, aspirin, ibuprofen, Tylenol, Pepto Bismol, Tums, Lipitor, Senokot, Motrin, Maalox, Ex-Lax, Benadryl, Sudafed, Preparation H, Claritin, Prilosec, and Zoloft.........

The COVID-19–related lockdown has profoundly changed human behaviors and habits, impairing general and psychological well-being. Along with psychosocial consequences, it is possible that sexual behavior was also affected.
With the present study, we evaluated the impact of the community-wide containment and consequent social distancing on the intrapsychic, relational, and sexual health through standardized psychometric tools.
A case-control study was performed through a web-based survey and comparing subjects of both genders with (group A, N = 2,608) and without (group B, N = 4,213) sexual activity during lockdown. The Welch and chi-square tests were used to assess differences between groups. Univariate analysis of covariance, logistic regression models, and structural equation modeling were performed to measure influence and mediation effects of sexual activity on psychological, relational, and sexual outcomes.
Main outcome measures were General Anxiety Disorder-7 for anxiety, Patient Health Questionnaire-9 for depression, Dyadic Adjustment Scale for quality of relationship and a set of well-validated sexological inventories (International Index of Erectile Function, Female Sexual Function Index, and male-female versions of the Orgasmometer).
Anxiety and depression scores were significantly lower in subjects sexually active during lockdown. Analysis of covariance identified gender, sexual activity, and living without partner during lockdown as significantly affecting anxiety and depression scores (P < .0001). Logistic regression models showed that lack of sexual activity during lockdown was associated with a significantly higher risk of developing anxiety and depression (OR: 1.32 [95% CI: 1.12 - 1.57, P < .001] and 1.34 [95% CI: 1.15 - 1.57, P < .0001], respectively). Structural equation modeling evidenced the protective role of sexual activity toward psychological distress (βmales = -0.18 and βfemales = -0.14), relational health (βmales = 0.26 and βfemales = 0.29) and sexual health, both directly (βmales = 0.43 and βfemales = 0.31), and indirectly (βmales = 0.13 and βfemales = 0.13).
The demonstrated mutual influence of sexual health on psychological and relational health could direct the clinical community toward a reinterpretation of the relationship among these factors.
Strengths and limitations
Based on a large number of subjects and well-validated psychometric tools, this study elucidated the protective role of sexual activity for psychological distress, as well for relational and sexual health. Main limitations were the web-based characteristics of the protocol and the retrospective nature of prelockdown data on psychorelational and sexual health of subjects recruited
COVID-19 lockdown dramatically impacted on psychological, relational, and sexual health of the population. In this scenario, sexual activity played a protective effect, in both genders, on the quarantine-related plague of anxiety and mood disorders

Some of the first Americans may have been Australians. A new study of Brazilian skulls ranging from 11,000 to 7,500 years old has revealed that they have more in common with Aboriginal Australians and Melanesians than modern Native Americans.
"The earliest Americans are very different from nowadays Indians or later archaeological material," says Walter Neves of the University of Sao Paulo in Brazil, co-author of the study that is being published online this week by the Proceedings of the National Academy of Sciences. "We are proposing that the Americas were populated by waves of humans."
Neves and his colleague Mark Hubbe studied skulls found in the Lagoa Santa region of central Brazil, an area riddled with caves. Since 1842, at least 250 ancient human skeletons ranging from ancient to nearly modern have turned up there. The scientists dated 22 of the oldest specimens by measuring their isotopes and found them to be between 8,500 and 7,500 years old.
The researchers then enlarged this sample by including all remains buried in a similar fashion--in shallow graves covered with small blocks of limestone or quartz--which they presume to hail from the same time period as the dated material. They ended up with 55 well preserved skulls that fit the criteria and compared them with standardized skull measurements of more than 2,500 modern humans. By comparing the size and shape of the skulls as well as their noses and eye sockets, Neves found that the oldest Brazilian specimens most closely resembled the skulls of the Tolai people of New Britain in Papua New Guinea, followed by other Australo-Melanesians. The closest match among modern Native Americans are Eskimos. "Eskimos get close because they are one of the few American Indians to have a long skull," Neves explains.
This broader skull data seems to support Neves' theory that two distinct waves of people populated the Americas, perhaps both crossing the Bering Strait during different periods. But recent genetic studies have been interpreted to indicate only one such migration. "DNA lineages are often lost during the course of evolution, even in short periods of time," Neves counters. "Today, no South American native group presents the X [mitochondrial DNA] lineage, which is universal among North American native groups. However, DNA extracted a few years ago from human skeletons from the Brazilian Amazon, dated to only a couple thousand years ago, showed clearly that the X lineage was present in South America."....... https://www.scientificamerican.com/article/skulls-suggest-differing/

There may be Negrito DNA in local populations, but the signal is insignificant and cannot be used as the foundation for any claims of “blood” and ethnicity. There are no living Negritos on Taiwan and thus, they cannot be the locus of anyone’s nationalist beliefs.
By the same token, the Negrito groups are long thought to have moved across the southern part of the Asian supercontinent, to southeast Asia, and then spreading north and south. They did not enter Taiwan from the west and what is now China, but from the south. Hence, they adumbrate the pro-China view that Taiwan is linked to China because one way or another it is origin of everyone who has lived in Taiwan.
The Negritos were here first, and they were here for tens of thousands of years before anyone else.
Not out of China..........

The US initially suspected "sonic attacks" had been launched against its embassy in Havana
Mystery illness suffered by US diplomats in Cuba was most likely caused by directed microwave radiation, a US government report has found.
The report by the National Academies of Sciences does not attribute blame for the directed energy waves.
But it said research into the effects of pulsed radio frequency energy was carried out by the Soviet Union more than 50 years ago.
The illnesses first affected people at the US embassy in Havana in 2016-17.
Staff and some of their relatives complained of symptoms ranging from dizziness, loss of balance, hearing loss, anxiety and something they described as "cognitive fog". It became known as "Havana syndrome".
The US accused Cuba of carrying out "sonic attacks", which it strongly denied, and the incident led to increased tension between the two nations.
A 2019 US academic study found "brain abnormalities" in the diplomats who had fallen ill, but Cuba dismissed the report.
What is a covert sonic weapon?
US expels two Cuban UN diplomats
Canada also cut its embassy staff in Cuba after at least 14 of its citizens reported similar symptoms.
The latest study was carried out by a team of medical and scientific experts who examined the symptoms of about 40 government employees.
Many have suffered longstanding and debilitating effects, the report said.
"The committee felt that many of the distinctive and acute signs, symptoms and observations reported by (government) employees are consistent with the effects of directed, pulsed radio frequency (RF) energy," the report reads.
"Studies published in the open literature more than a half-century ago and over the subsequent decades by Western and Soviet sources provide circumstantial support for this possible mechanism."
Staff at the US consulate in Guangzhou, China, also reported strange symptoms
It noted there had been "significant research in Russia/USSR into the effects of pulsed, rather than continuous wave [radio frequency] exposures". It said that military personnel in "Eurasian communist countries" had been exposed to non-thermal radiation.
Cuba was not the only posting where US diplomats have reported the unusual symptoms.
In 2018, the US removed several officials from China after employees working in the southern city of Guangzhou reported "subtle and vague, but abnormal, sensations of sound and pressure". One US official was diagnosed with mild brain trauma.

Patients undergoing a panic attack (PA) or a hyperventilation attack (HVA) are sometimes admitted to emergency departments (EDs). Reduced serotonin level is known as one of the causes of PA and HVA. Serotonin is synthesized from tryptophan. For the synthesis of serotonin, vitamin B6 (Vit B6) and iron play important roles as cofactors. To clarify the pathophysiology of PA and HVA, we investigated the serum levels of vitamins B2, B6, and B12 and iron in patients with PA or HVA attending an ED.
We measured each parameter in 21 PA or HVA patients and compared the values with those from 20 volunteers. We found that both Vit B6 and iron levels were significantly lower in the PA/HVA group than in the volunteer group.
Reclaim Your Health & Freedom, The Biogetica Way
There was no significant difference in the serum levels of vitamins B2 or B12. These results suggest that low serum concentrations of Vit B6 and iron are involved in PA and HVA. Further studies are needed to clarify the mechanisms involved in such differences.

Zealandia illustrates that the large and the obvious in natural science can be overlooked. Based on various lines of geological and geophysical evidence, particularly those accumulated in the last two decades, we argue that Zealandia is not a collection of partly submerged continental fragments but is a coherent 4.9 Mkm2 continent (Fig. 1). Currently used conventions and definitions of continental crust, continents, and microcontinents require no modification to accommodate Zealandia.
Satellite gravity data sets, New Zealand’s UNCLOS program, and marine geological expeditions have been major influences in promoting the big picture view necessary to define and recognize Zealandia (Fig. 2). Zealandia is approximately the area of greater India and, like India, Australia, Antarctica, Africa, and South America, was a former part of the Gondwana supercontinent (Figs. 3 and 5). As well as being the seventh largest geological continent (Fig. 1), Zealandia is the youngest, thinnest, and most submerged (Fig. 4). The scientific value of classifying Zealandia as a continent is much more than just an extra name on a list. That a continent can be so submerged yet unfragmented makes it a useful and thought-provoking geodynamic end member in exploring the cohesion and breakup of continental crust.

The earliest dispersal of humans into North America is a contentious subject, and proposed early sites are required to meet the following criteria for acceptance: (1) archaeological evidence is found in a clearly defined and undisturbed geologic context; (2) age is determined by reliable radiometric dating; (3) multiple lines of evidence from interdisciplinary studies provide consistent results; and (4) unquestionable artefacts are found in primary context1,2. Here we describe the Cerutti Mastodon (CM) site, an archaeological site from the early late Pleistocene epoch, where in situ hammerstones and stone anvils occur in spatio-temporal association with fragmentary remains of a single mastodon (Mammut americanum). The CM site contains spiral-fractured bone and molar fragments, indicating that breakage occured while fresh. Several of these fragments also preserve evidence of percussion. The occurrence and distribution of bone, molar and stone refits suggest that breakage occurred at the site of burial. Five large cobbles (hammerstones and anvils) in the CM bone bed display use-wear and impact marks, and are hydraulically anomalous relative to the low-energy context of the enclosing sandy silt stratum. 230Th/U radiometric analysis of multiple bone specimens using diffusion–adsorption–decay dating models indicates a burial date of 130.7 ± 9.4 thousand years ago. These findings confirm the presence of an unidentified species of Homo at the CM site during the last interglacial period (MIS 5e; early late Pleistocene), indicating that humans with manual dexterity and the experiential knowledge to use hammerstones and anvils processed mastodon limb bones for marrow extraction and/or raw material for tool production. Systematic proboscidean bone reduction, evident at the CM site, fits within a broader pattern of Palaeolithic bone percussion technology in Africa3,4,5,6, Eurasia7,8,9 and North America10,11,12. The CM site is, to our knowledge, the oldest in situ, well-documented archaeological site in North America and, as such, substantially revises the timing of arrival of Homo into the Americas.

Invasive species are among the world's greatest threats to native species and biodiversity. Once invasive plants become established, they can alter soil chemistry and shift nutrient cycling in an ecosystem. This can have important impacts not only on plant composition, diversity, and succession within a community, but also in the cycling of critical elements like carbon and nitrogen on a larger, potentially even global, scale. Clearly, both native and exotic plants form intimate relationships with bacteria in the soil that facilitate the extraction and conversion of elements to biologically usable forms. Yet an unanswered question with regard to plant invasions remains: could the changes in soil biogeochemistry be due to an advantage that invasive plants get from interacting with their microbiome?
When alien species invade and take over communities, they may not come alone -- many plant species are host to a whole suite of microorganisms that not only live in plant cells, but also in the soil surrounding the plants' roots. These microbes form close, often mutualistic, associations with their plant hosts. Some convert atmospheric nitrogen into bioavailable forms that are then exchanged for carbon from the plant. Bioavailable nitrogen is frequently limiting in soils, yet many invaded ecosystems have more carbon and nitrogen in plant tissues and soils compared with systems dominated by native plants. Since changes in the soil nitrogen cycle are driven by microbes, could bacteria associated with invasive species not only be responsible for the observed changes in soil nutrient concentrations, but also for enabling the continued growth and persistence of the invader species?
These were the kinds of questions that started percolating for Marnie Rout (University of North Texas Health Science Center) after she drove by a remnant tallgrass prairie in North Central Texas as a beginning graduate student. She was particularly struck by the obvious and drastic changes the native prairie was undergoing due to the invasion of an exotic grass.
"It literally looked like someone had drawn a line down the field," Rout explained. "On one side was the native prairie, the other side had this towering monoculture of invasive Sorghum. The plant looked like it was invading in a military fashion, forming this distinct line that was clearly visible."
Subsequent literature searches led to the discovery that sugar cane, an agriculturally important crop, is a nitrogen fixer that contains bacterial endophytes, and Rout became curious if the microbes she and her colleague Tom Chrzanowski (The University of Texas Arlington) discovered in invasive Sorghum might be providing similar benefits to this invasive plant.
Rout combined forces with colleagues from The University of Montana, The University of Texas Arlington, and University of Washington to investigate whether the differences in soil nutrient concentrations found in an invaded prairie could be due to metabolic processes of the bacterial microbiome associated with the invasive grass, and to determine whether these microbial agents facilitate the perpetuation and spread of this invasive grass. They published their findings in a Special Section in the American Journal of Botany on Rhizosphere Interactions: The Root Biome.
"Things attributed to plant-plant interactions like competition and facilitation are likely under more microbial regulation than we have been giving them credit," Rout commented. "Studying disruptions to ecosystems like those seen in plant invasions provides a window into something -- specifically the process of co-evolution -- that we normally don't get to observe in a single human lifetime."
Indeed, the alarming rate -- almost 0.5 meters a year -- at which the invasive grass Sorghum halepense has invaded the tallgrass prairie, formerly dominated by the native little bluestem (Schizachyrium scoparium), over the last 25 years, and the complete dominance of that invasive was the ideal situation in which Rout could test her ideas.
Rout and colleagues first confirmed that the invaded soils of the prairie did indeed have higher levels of nitrogen, phosphorous, and iron-derived chemicals compared with the non-invaded prairie soils still dominated by native plants. They then tested whether the interactions between the dominant invasive grass and the soil biota could be responsible for the observed changes in the soil nutrient concentrations.
By isolating five bacterial strains of endophytes found inside S. halepense rhizomes (subterranean stems used for storage and vegetative reproduction) and growing them in the lab in different mixtures of substrates, the authors determined that these microbes were able to fix and mobilize nitrogen, phosphorus, and iron. All three are important elements associated with plant growth; however, some were produced in excess of what would be needed for plant growth. Indeed, perhaps somewhat alarmingly, the amount of iron that was produced reached levels that are toxic to many crops -- and may even inhibit establishment of native species.
Furthermore, the authors were able to show that not only can this invasive plant acquire microbes from the environment, but that it is also capable of passing them on to the next generation via seeds. Using a sophisticated series of intricate experiments involving growing seedlings from surface sterilized seeds in nitrogen- deprived or nitrogen-augmented soils and slurries with different suites of soil microbes, Rout and colleagues showed that these microbes enabled the grass to produce 5-fold increases in rhizomes, a primary mechanism driving invasions of this species.......... https://www.sciencedaily.com/releases/2013/09/130926131631.htm

A multiphase study was performed to find an effective method to evaluate electromagnetic field (EMF) sensitivity of patients. The first phase developed criteria for controlled testing using an environment low in chemical, particulate, and EMF pollution. Monitoring devices were used in an effort to ensure that extraneous EMF would not interfere with the tests. A second phase involved a single-blind challenge of 100 patients who complained of EMF sensitivity to a series of fields ranging from 0 to 5 MHz in frequency, plus 5 blank challenges. Twenty-five patients were found who were sensitive to the fields, but did not react to the blanks. These were compared in the third phase to 25 healthy naive volunteer controls. None of the volunteers reacted to any challenge, active or blank, but 16 of the EMF-sensitive patients (64%) had positive signs and symptoms scores, plus autonomic nervous system changes. In the fourth phase, the 16 EMF-sensitive patients were rechallenged twice to the frequencies to which they were most sensitive during the previous challenge. The active frequency was found to be positive in 100% of the challenges, while all of the placebo tests were negative. we concluded that this study gives strong evidence that electromagnetic field sensitivity exists, and can be elicited under environmentally controlled conditions.
