Museum specimens could help fight the next pandemic – why preserving collections is crucial to future scientific discoveries

Specimen preservation means researchers don’t need to reinvent the wheel each time they ask a new question, making it critical for the advancement of science. But many specimens are discarded or lost.

Imagine yourself as the first naturalist to stand in a place where little recorded scientific knowledge exists, like Alfred Russel Wallace in the Malay Archipelago or Alexander von Humboldt in the Americas in the early 1800s. The notes you record will expand humanity’s scientific knowledge of the natural world, and the specimens of plants and animals you collect are destined to be used for centuries to describe past and present biodiversity and make new discoveries in biomedicine and beyond.

Now, imagine if those specimens were never collected.

That’s what it’s like if samples from the field are not archived. Natural history museums are the guardians of specimens, ensuring their future availability to the scientific community on shelves, in libraries and through curated online databases. Yet, despite scientists continuing to sample the natural world, many specimens are not ending up in biorepositories. If specimens are not archived, the next generation of scientists will inevitably have to reinvent the wheel, spending more time and money resampling the world’s species and geography to answer future questions.

There’s a variety of reasons that specimens don’t get saved, including insufficient museum-based training among newer generations of scientists, poor funding of natural history collections and a lapse in data priorities from organizations that fund and disseminate scientific knowledge.

In a new paper published in the journal BioScience, we and our colleagues outline how existing loopholes in U.S. federal data policies, backward data priorities by scientific journals and a culture of data ownership have made it too easy for research specimens to be discarded. This problem stands to hamstring scientific progress. But, it’s not too late to change.

Old specimens, new discoveries

When archived in museums, specimens – literally, the bones, skins and tissues of biodiversity – can be used and reused to answer new scientific questions over time, including many of societal concern.

An all-too-familiar example these days is the use of preserved tissues to trace the origins of zoonotic diseases – that is, diseases that come from animals. Most emerging diseases in people are zoonotic, including COVID-19, rabies, MERS and Ebola.

Properly preserved wildlife specimens, often collected for a completely different purpose – wildlife conservation or ecological research, for example – make museum biorepositories a vital player in public health research. Each archived sample can be used to identify the wildlife sources of a disease, monitor changes in disease prevalence and distribution over time, and identify environmental variables that may lead to spillover into people.

In the early 1990s, an unknown lethal virus jumped into humans, killing 13 people in the American Southwest. Mammal specimens, originally sampled for other reasons and preserved at the Museum of Southwestern Biology, were used by researchers to identify the pathogen as a hantavirus and its wildlife source as deer mice. Museum specimens also provided evidence that the virus had been circulating in Southwestern rodent populations for over a decade, and its emergence in humans was linked to El Niño climate cycles. In this way, museum collections provide hard evidence for rapid, scientifically informed public health guidance.

Unfortunately, the origins of COVID-19 have been harder to pinpoint – in part because the number and diversity of specimens available to the scientific community, particularly from Asia and other remote regions, is decreasing.

Federal policies can encourage preservation

The U.S. government has started to prioritize genomic data security, but it is not the first to recognize the importance of these data. Currently, the majority of American genetic data is owned by foreign entities, most notably Russia and China, as a consequence of lax international biosecurity measures and substantial foreign investment in genomics and biomedicine.

In response, the National Institutes of Health Genomic Data Sharing Policy now promotes archiving molecular sequence data (that is, DNA and RNA) generated from tissue samples.

This policy is a step in the right direction, but it fails to address equivalent archival requirements for specimens – the raw material for many DNA sequences used in biodiversity and biomedical research. The irrevocable loss of specimens poses a major risk to national security, public health and science.

Other federal agencies are also taking steps in the right direction, but there is room for improvement. For example, recent updates to the U.S. Geological Survey’s data policies extend “FAIR” principles to species – meaning specimens must be Findable, Accessible, Interoperable and Reusable. USGS also holds the specimen’s collector responsible for ensuring its long-term care. Although these policies apply to USGS scientists, they’re a good model of specimen stewardship for the entire scientific community.

Unfortunately, in extreme cases, the same policy also allows specimens collected with federal funds to be destroyed if deemed “no longer of value or potential use [to] USGS.” Given the irreplaceable nature of specimens, we argue that destruction is rarely justifiable. Instead, preservation of specimens in museums at the conclusion of a project better aligns with national mandates to ensure open publication of federal data and helps meet the responsibility of making these data available to the public.

Scientific journals can set a priority

As federal guidelines take shape, scientists themselves have a responsibility to ensure responsible specimen archival to foster the democratization of biological science through increased access.

One place to act may be during the publication of research papers – a cornerstone of the scientific enterprise.

More than half of the top 100 journals in ecology, evolution, behavior and systematics mention or require the permanent archival of DNA sequences. But fewer than one-fifth have similar requirements for specimens. If specimens are preserved, DNA sequences can always be regenerated.

Inconsistent data requirements across journals mean that authors can skirt the responsibility of archiving specimens by sending their work to journals with looser policies. During the peer-review process of both grant proposals and research papers, scientists – as editors and reviewers – have an opportunity to encourage responsible specimen archival.

A history of ownership versus stewardship

Inconsistent specimen archival may also reflect the broader approach to science, much of which is passed down from early Western naturalists – like Wallace and von Humboldt. There is a persistent ethos of data ownership, rather than stewardship, born from competition among scientists that ultimately fosters a fear of being scooped.

The famous 19th-century correspondence between Charles Darwin and Wallace, which prompted Darwin to quickly finalize his own writings on natural selection, is one example of such competition. But the tension over “who found it first” is still with scientists today. Museums have protocols in place to allay many of these fears, including delayed data release policies and temporary embargoes that allow researchers to finish projects before their data are made available to the public.

We and our colleagues have proposed guidelines aimed at turning the corner on downward trends in specimen preservation. We recommend integrating specimen stewardship plans into existing requirements for data management plans, by treating specimens as the primary data they are. Early collaboration, budgeting and planning between researchers and natural history museums will be essential to ensure that physical space and financial resources are available to store new collections. Normalizing specimen archival with museums will build a rich foundation of genetic resources for the next generation of scientists.

Buried Project Veritas Recording Shows Top Pfizer Scientists Suppressed Concerns Over COVID-19 Boosters, MRNA Tech

Submitted by Liam Cosgrove

Former Project Veritas & O’Keefe Media Group operative and Pfizer formulation analyst scientist Justin Leslie revealed previously unpublished recordings showing Pfizer’s top vaccine researchers discussing major concerns surrounding COVID-19 vaccines. Leslie delivered these recordings to Veritas in late 2021, but they were never published:

Featured in Leslie’s footage is Kanwal Gill, a principal scientist at Pfizer. Gill was weary of MRNA technology given its long research history yet lack of approved commercial products. She called the vaccines “sneaky,” suggesting latent side effects could emerge in time.

Gill goes on to illustrate how the vaccine formulation process was dramatically rushed under the FDA’s Emergency Use Authorization and adds that profit incentives likely played a role:

"It’s going to affect my heart, and I’m going to die. And nobody’s talking about that."

Leslie recorded another colleague, Pfizer’s pharmaceutical formulation scientist Ramin Darvari, who raised the since-validated concern that repeat booster intake could damage the cardiovascular system:

None of these claims will be shocking to hear in 2024, but it is telling that high-level Pfizer researchers were discussing these topics in private while the company assured the public of “no serious safety concerns” upon the jab’s release:

Vaccine for Children is a Different Formulation

Leslie sent me a little-known FDA-Pfizer conference — a 7-hour Zoom meeting published in tandem with the approval of the vaccine for 5 – 11 year-olds — during which Pfizer’s vice presidents of vaccine research and development, Nicholas Warne and William Gruber, discussed a last-minute change to the vaccine’s “buffer” — from “PBS” to “Tris” — to improve its shelf life. For about 30 seconds of these 7 hours, Gruber acknowledged that the new formula was NOT the one used in clinical trials (emphasis mine):


“The studies were done using the same volume… but contained the PBS buffer. We obviously had extensive consultations with the FDA and it was determined that the clinical studies were not required because, again, the LNP and the MRNA are the same and the behavior — in terms of reactogenicity and efficacy — are expected to be the same.

According to Leslie, the tweaked “buffer” dramatically changed the temperature needed for storage: “Before they changed this last step of the formulation, the formula was to be kept at -80 degrees Celsius. After they changed the last step, we kept them at 2 to 8 degrees celsius,” Leslie told me.

The claims are backed up in the referenced video presentation:

I’m no vaccinologist but an 80-degree temperature delta — and a 5x shelf-life in a warmer climate — seems like a significant change that might warrant clinical trials before commercial release.

Despite this information technically being public, there has been virtually no media scrutiny or even coverage — and in fact, most were told the vaccine for children was the same formula but just a smaller dose — which is perhaps due to a combination of the information being buried within a 7-hour jargon-filled presentation and our media being totally dysfunctional.

Bohemian Grove?

Leslie’s 2-hour long documentary on his experience at both Pfizer and O’Keefe’s companies concludes on an interesting note: James O’Keefe attended an outing at the Bohemian Grove.

Leslie offers this photo of James’ Bohemian Grove “GATE” slip as evidence, left on his work desk atop a copy of his book, “American Muckraker”:

My thoughts on the Bohemian Grove: my good friend’s dad was its general manager for several decades. From what I have gathered through that connection, the Bohemian Grove is not some version of the Illuminati, at least not in the institutional sense.

Do powerful elites hangout there? Absolutely. Do they discuss their plans for the world while hanging out there? I’m sure it has happened. Do they have a weird ritual with a giant owl? Yep, Alex Jones showed that to the world.

My perspective is based on conversations with my friend and my belief that his father is not lying to him. I could be wrong and am open to evidence — like if boxer Ryan Garcia decides to produce evidence regarding his rape claims — and I do find it a bit strange the club would invite O’Keefe who is notorious for covertly filming, but Occam’s razor would lead me to believe the club is — as it was under my friend’s dad — run by boomer conservatives the extent of whose politics include disliking wokeness, immigration, and Biden (common subjects of O’Keefe’s work).

Therefore, I don’t find O’Keefe’s visit to the club indicative that he is some sort of Operation Mockingbird asset as Leslie tries to depict (however Mockingbird is a 100% legitimate conspiracy). I have also met James several times and even came close to joining OMG. While I disagreed with James on the significance of many of his stories — finding some to be overhyped and showy — I never doubted his conviction in them.

As for why Leslie’s story was squashed… all my sources told me it was to avoid jail time for Veritas executives.

Feel free to watch Leslie’s full documentary here and decide for yourself.

Fun fact — Justin Leslie was also the operative behind this mega-viral Project Veritas story where Pfizer’s director of R&D claimed the company was privately mutating COVID-19 behind closed doors:

“[…] our findings support the hypothesis that the intrauterine environment, particularly essential and non-essential metals, affect epigenetic aging biomarkers across the life course.”

BUFFALO, NY- March 12, 2024 – A new research paper was published in Aging (listed by MEDLINE/PubMed as “Aging (Albany NY)” and “Aging-US” by Web of Science) Volume 16, Issue 4, entitled, “Associations of prenatal one-carbon metabolism nutrients and metals with epigenetic aging biomarkers at birth and in childhood in a US cohort.”

Epigenetic gestational age acceleration (EGAA) at birth and epigenetic age acceleration (EAA) in childhood may be biomarkers of the intrauterine environment. In this new study, researchers Anne K. Bozack, Sheryl L. Rifas-Shiman, Andrea A. Baccarelli, Robert O. Wright, Diane R. Gold, Emily Oken, Marie-France Hivert, and Andres Cardenas from Stanford University School of Medicine, Harvard Medical School, Harvard T.H. Chan School of Public Health, Columbia University, and Icahn School of Medicine at Mount Sinai investigated the extent to which first-trimester folate, B12, 5 essential and 7 non-essential metals in maternal circulation are associated with EGAA and EAA in early life. 

“[…] we hypothesized that OCM [one-carbon metabolism] nutrients and essential metals would be positively associated with EGAA and non-essential metals would be negatively associated with EGAA. We also investigated nonlinear associations and associations with mixtures of micronutrients and metals.”

Bohlin EGAA and Horvath pan-tissue and skin and blood EAA were calculated using DNA methylation measured in cord blood (N=351) and mid-childhood blood (N=326; median age = 7.7 years) in the Project Viva pre-birth cohort. A one standard deviation increase in individual essential metals (copper, manganese, and zinc) was associated with 0.94-1.2 weeks lower Horvath EAA at birth, and patterns of exposures identified by exploratory factor analysis suggested that a common source of essential metals was associated with Horvath EAA. The researchers also observed evidence of nonlinear associations of zinc with Bohlin EGAA, magnesium and lead with Horvath EAA, and cesium with skin and blood EAA at birth. Overall, associations at birth did not persist in mid-childhood; however, arsenic was associated with greater EAA at birth and in childhood. 

“Prenatal metals, including essential metals and arsenic, are associated with epigenetic aging in early life, which might be associated with future health.”

A beginner’s guide to the taxes you’ll hear about this election season

Everything you need to know about income tax, national insurance and more.

Cast Of Thousands/Shutterstock

National insurance, income tax, VAT, capital gains tax, inheritance tax… it’s easy to get confused about the many different ways we contribute to the cost of running the country. The budget announcement is the key time each year when the government shares its financial plans with us all, and announces changes that may make a tangible difference to what you pay.

But you’ll likely be hearing a lot more about taxes in the coming months – promises to cut or raise them are an easy win (or lose) for politicians in an election year. We may even get at least one “mini-budget”.

If you’ve recently entered the workforce or the housing market, you may still be wrapping your mind around all of these terms. Here is what you need to know about the different types of taxes and how they affect you.

The UK broadly uses three ways to collect tax:

1. When you earn money

If you are an employee or own a business, taxes are deducted from your salary or profits you make. For most people, this happens in two ways: income tax, and national insurance contributions (or NICs).

If you are self-employed, you will have to pay your taxes via an annual tax return assessment. You might also have to pay taxes this way for interest you earn on savings, dividends (distribution of profits from a company or shares you own) received and most other forms of income not taxed before you get it.

Around two-thirds of taxes collected come from people’s or business’ incomes in the UK.

2. When you spend money

VAT and excise duties are taxes on most goods and services you buy, with some exceptions like books and children’s clothing. About 20% of the total tax collected is VAT.

3. Taxes on wealth and assets

These are mainly taxes on the money you earn if you sell assets (like property or stocks) for more than you bought them for, or when you pass on assets in an inheritance. In the latter case in the UK, the recipient doesn’t pay this, it is the estate paying it out that must cover this if due. These taxes contribute only about 3% to the total tax collected.

You also likely have to pay council tax, which is set by the council you live in based on the value of your house or flat. It is paid by the user of the property, no matter if you own or rent. If you are a full-time student or on some apprenticeship schemes, you may get a deduction or not have to pay council tax at all.

This article is part of Quarter Life, a series about issues affecting those of us in our 20s and 30s. From the challenges of beginning a career and taking care of our mental health, to the excitement of starting a family, adopting a pet or just making friends as an adult. The articles in this series explore the questions and bring answers as we navigate this turbulent period of life.

Put together, these totalled almost £790 billion in 2022-23, which the government spends on public services such as the NHS, schools and social care. The government collects taxes from all sources and sets its spending plans accordingly, borrowing to make up any difference between the two.

Income tax

The amount of income tax you pay is determined by where your income sits in a series of “bands” set by the government. Almost everyone is entitled to a “personal allowance”, currently £12,570, which you can earn without needing to pay any income tax.

You then pay 20% in tax on each pound of income you earn (across all sources) from £12,570-£50,270. You pay 40% on each extra pound up to £125,140 and 45% over this. If you earn more than £100,000, the personal allowance (amount of untaxed income) starts to decrease.

If you are self-employed, the same rates apply to you. You just don’t have an employer to take this off your salary each month. Instead, you have to make sure you have enough money at the end of the year to pay this directly to the government.

The government can increase the threshold limits to adjust for inflation. This tries to ensure any wage rise you get in response to higher prices doesn’t lead to you having to pay a higher tax rate. However, the government announced in 2021 that they would freeze these thresholds until 2026 (extended now to 2028), arguing that it would help repay the costs of the pandemic.

Given wages are now rising for many to help with the cost of living crisis, this means many people will pay more income tax this coming year than they did before. This is sometimes referred to as “fiscal drag” – where lower earners are “dragged” into paying higher tax rates, or being taxed on more of their income.

National insurance

National insurance contributions (NICs) are a second “tax” you pay on your income – or to be precise, on your earned income (your salary). You don’t pay this on some forms of income, including savings or dividends, and you also don’t pay it once you reach state retirement age (currently 66).

While Jeremy Hunt, the current chancellor of the exchequer, didn’t adjust income tax meaningfully in this year’s budget, he did announce a cut to NICs. This was a surprise to many, as we had already seen rates fall from 12% to 10% on incomes higher than £242/week in January. It will now fall again to 8% from April.

While this is charged separately to income tax, in reality it all just goes into one pot with other taxes. Some, including the chancellor, say it is time to merge these two deductions and make this simpler for everyone. In his budget speech this year, Hunt said he’d like to see this tax go entirely. He thinks this isn’t fair on those who have to pay it, as it is only charged on some forms of income and on some workers.

I wouldn’t hold my breath for this to happen however, and even if it did, there are huge sums linked to NICs (nearly £180bn last year) so it would almost certainly have to be collected from elsewhere (such as via an increase in income taxes, or a lot more borrowing) to make sure the government could still balance its books.

Other taxes

There are likely to be further tweaks to the UK’s tax system soon, perhaps by the current government before the election – and almost certainly if there is a change of government.

Wealth taxes may be in line for a change. In the budget, the chancellor reduced capital gains taxes on sales of assets such as second properties (from 28% to 24%). These types of taxes provide only a limited amount of money to the government, as quite high thresholds apply for inheritance tax (up to £1 million if you are passing on a family home).

There are calls from many quarters though to look again at these types of taxes. Wealth inequality (the differences between total wealth held by the richest compared to the poorest) in the UK is very high (much higher than income inequality) and rising.

But how to do this effectively is a matter of much debate. A recent study suggested a one-off tax on total wealth held over a certain threshold might work. But wealth taxes are challenging to make work in practice, and both main political parties have already said this isn’t an option they are considering currently.
