Another tool in the fight against cancer

Cancer is many things, so one tool or technique cannot be used against all, but even so, it is good news every time a new tool has been discovered that can help fight some cancers.

From ScienceDaily: Light switch wakes sleeping cancer cells and makes them vulnerable again

Some cancer cells evade treatment by entering a dormant state triggered by stress hormones. ETH Zurich scientists have created a light-controlled molecular switch that selectively destroys the receptors responsible for this survival mode. In laboratory lung cancer cells, the approach woke sleeping tumor cells and could help make future cancer therapies more effective while minimizing damage to healthy tissue.

It sounds counterintuitive that you want the cancer cells to be active, but the ScienceDaily article explains it:

In certain forms of cancer, including some types of lung cancer, stress hormones can trigger this response. Specialized proteins called glucocorticoid receptors detect those hormones inside tumor cells. Once activated, the receptors can push the cells into a dormant state where cell division slows dramatically. As a result, many therapies become far less effective.

So, in other words, we can only fight them effectively when they are active.

The ScienceDaily article is based upon the paper Light-controlled disruption of cancer cell dormancy via photoswitchable stress hormone receptor degraders by Karina M. Freitag et al in PNAS.

I will freely admit that the actual paper is a bit above my biochemistry level, but the “significance” section is fairly understandable, especially combined with the ScienceDaily writeup

Stress hormone signaling through the glucocorticoid receptor (GR) induces a reversible, drug-tolerant dormancy state in cancer cells. However, systemic GR depletion is not viable due to its essential roles in non-pathological physiology. In this study, we developed light-responsive Proteolysis Targeting Chimeras (photoPROTACs) that enable reversible, wavelength-specific control of GR degradation. PhotoPROTACs featuring arylazopyrazole photoswitches showed potent, isomer-dependent GR degradation and high target specificity at nanomolar concentrations. In addition, transcriptomic profiling in lung cancer cells revealed that only the active isomer disrupts dormancy-associated gene networks, highlighting the potential of photoPROTACs to target GR-driven dormancy exclusively in cancerous tissue.

Barriers to reproducibility

I came across an interest research article in PLOS One:

What helps and hinders reproducible research? Researchers’ perspectives from a cross-disciplinary interview study by Magdalena Kozula et al.

Debates and policy initiatives addressing research reproducibility have expanded considerably in recent years. Yet, many of these measures remain generic and risk overlooking the lived realities of research practice. This study aims to explore researchers’ perspectives on the barriers, facilitators, and motivators that shape reproducible research across diverse fields and career stages, using qualitative methods. Semi-structured interviews were conducted with 60 researchers affiliated with universities and research institutions across the European Union and the United Kingdom. Participants were sampled to ensure diversity in discipline, career stage, gender, and geography.

As is set forth already in the abstract, there are five themes for barriers and facilitators influencing reproducibility:

  • navigating the research ecosystem – incentives and policies of institutions, journals, and funders
  • social and cultural dynamics as drivers and barriers – disciplinary norms, generational differences, competition, and collaboration
  • resourcing reproducibility – skills, infrastructure, guidelines and standards, time, funding, and awareness
  • inside the research process – field-specific constraints, methodological transparency, research material sharing, and external restrictions
  • personal commitment to shared responsibility – reflective motivations, pragmatic drivers, and perceptions of accountability

Looking at these themes it is hardly surprising that we are still facing reproducibility issues. As the abstract goes on to explain

Researchers described reproducibility as less of an individual choice but as a socially and institutionally mediated activity, dependent on enabling conditions such as supportive policies, adequate infrastructure, and equitable resource distribution. Reproducibility reform cannot rely solely on individual researcher commitment or one-size-fits-all policies. Effective interventions must account for disciplinary and methodological diversity, provide targeted resources and training, and realign incentive structures to reward transparency and rigour. These findings highlight reproducibility as a collective responsibility across the research ecosystem, requiring coordinated action by researchers, institutions, funders, and publishers. Promoting reproducible practices in this systemic, context-sensitive manner is essential for fostering a more credible, equitable, and sustainable scientific enterprise.

The scientific process is still the best way to find out things, but unfortunately, our current system rewards new findings over reproducing findings. New discoveries get papers in Science, Nature etc. while attempts at reproduction at best get a foot-note, unless they fail, and show some theory or discovery to be wrong. And even then, most of the time, they won’t get an paper, but at most a retraction of the original paper.

I work in the world of software development, where we have the concept of technical debt. This is stuff that we ought to do, or redo, but which we postpone until the costs and consequences of the “debt” is too high to ignore. It might be some complex piece of code, that really needs to be simplified, but which works – but every time anyone needs to change anything in it, something important breaks, and a lot of time needs to be spent on fixing it.

In my opinion reproducibility is the technical debt of the science fields. It can be ignored, until the costs are too high, and it turns out that the fundament a lot of work is based on, is deeply flawed.

One way of handling technical debt in software development, is to set aside a certain percentage of your time to go back and “pay” the debt. I.e. time where you actually revisit the issues and fix the problems instead of pushing it ahead in an ever increasing pile.

Maybe something similar could be done in research. Make sure that a certain percentage of resources are set aside to replicate findings from other peoples’ research. Not in order to debunk the work of others, but in order to make sure that the fundament the current research is built upon, is firm.

Anyway, please read the article, it is interesting and also shows clearly why we are nowhere near removing the barriers to reproducibility.

Something completely different; while reading the PLOS One research article, I couldn’t help think about a 2019 American Economic Review article:

Does Science Advance One Funeral at a Time? by Pierre Azoulay, Christian Fons-Rosen, and Joshua S. Graff Zivin

We examine how the premature death of eminent life scientists alters the vitality of their fields. While the flow of articles by collaborators into affected fields decreases after the death of a star scientist, the flow of articles by non-collaborators increases markedly. This surge in contributions from outsiders draws upon a different scientific corpus and is disproportionately likely to be highly cited. While outsiders appear reluctant to challenge leadership within a field when the star is alive, the loss of a luminary provides an opportunity for fields to evolve in new directions that advance the frontier of knowledge

I can’t help we would something similar in regards to reproducibility. If there is a grand old man (and it is pretty much always a man) in a given field, it is highly unlikely that he and his disciples’ findings would be challenged on the grounds of reproducibility. However when the grand old man leaves the field, this might change and people will start question the validity of the original research, and try to reproduce it.

Sounds and chimpanzees

Surfing the internet, I noted two pieces of news related to Chimpanzees and sounds.

The first article is about the rhythms that different groups of chimpanzees drum with, indicating that chimpanzees share musicality with humans.

Chimpanzee groups drum with distinct rhythms

New research from a team of cognitive scientists and evolutionary biologists finds that chimpanzees drum rhythmically, using regular spacing between drum hits. Their results show that eastern and western chimpanzees — two distinct subspecies — drum with distinguishable rhythms. The researchers say these findings suggest that the building blocks of human musicality arose in a common ancestor of chimpanzees and humans.

The actual science article was printed in Current BiologyChimpanzee drumming shows rhythmicity and subspecies variation

The second article is about how wild chimpanzees alter the meaning of singles calls when embedding them in longer calls, indicating a linguistic complexity that hasn’t been documented before outside the human species.

The origins of language (horrible headline given by ScienceDaily)

Wild chimpanzees alter the meaning of single calls when embedding them into diverse call combinations, mirroring linguistic operations in human language. Human language, however, allows an infinite generation of meaning by combining phonemes into words and words into sentences. This contrasts with the very few meaningful combinations reported in animals, leaving the mystery of human language evolution unresolved.

Chimpanzees are capable of complex communication: The human capacity for language may not be as unique as previously thought. Chimpanzees have a complex communication system that allows them to combine calls to create new meanings, similar to human language. Combining calls creatively: Chimpanzees use four ways to change meaning when combining single calls into two-call combinations, including compositional and non-compositional combinations, and they use a large variety of call combinations in a wide range of contexts.

The science article is in ScienceAdvancesVersatile use of chimpanzee call combinations promotes meaning expansion

Abstract

Language is a combinatorial communication system able to generate an infinite number of meanings. Nonhuman animals use several combinatorial mechanisms to expand meanings, but maximum one mechanism is reported per species, suggesting an evolutionary leap to human language. We tested whether chimpanzees use several meaning-expanding mechanisms. We recorded 4323 utterances in 53 wild chimpanzees and compared the events in which chimpanzees emitted two-call vocal combinations (bigrams) with those eliciting the component calls. Examining 16 bigrams, we found four combinatorial mechanisms whereby bigram meanings were or were not derived from the meaning of their parts—compositional or noncompositional combinations, respectively. Chimpanzees used each mechanism in several bigrams across a wide range of daily events. This combinatorial system allows encoding many more meanings than there are call types. Such a system in nonhuman animals has never been documented and may be transitional between rudimentary systems and open-ended systems like human language.

I found it interesting that two articles came out at the same time, seemingly unrelated, that both indicates that we share more traits with our Chimpanzee relatives than previously thought

 

Learn some real archaeology

A bunch of archaeologist and other online creators have come together to do an online event where they teach real archaeology – they call this initiative real archaeology:

Real Archaeology was started by a collective of online creators who produce fact-based content about the past. Our goal is to collaborate in creating, promoting, and sharing entertaining and educational media with the wider public on the wonders of our shared history.

We use peer-reviewed sources and our experience as researchers, teachers, archaeologists, historians, and more to bring history to life and make it accessible to as wide an audience as possible. As a part of our efforts to spread our message, we have created the Real Archaeology online event that spans three days in October.

During this time, our speakers will be releasing a myriad of archaeology-related content across multiple platforms including YouTube, TikTok, and Instagram. Follow our creators (list below) or search #realarchaeology to find and engage with our material.

The event started yesterday, but there is still time to catch the schedule today and tomorrow

A graph exploration method for identifying influential spreaders in complex networks

The problem of identifying the influential spreaders – the important nodes – in a real world network is of high importance due to its theoretical interest as well as its practical applications, such as the acceleration of information diffusion, the control of the spread of a disease and the improvement of the resilience of networks to external attacks. In this paper, we propose a graph exploration sampling method that accurately identifies the influential spreaders in a complex network, without any prior knowledge of the original graph, apart from the collected samples/subgraphs. The method explores the graph, following a deterministic selection rule and outputs a graph sample – the set of edges that have been crossed. The proposed method is based on a version of Rank Degree graph sampling algorithm. We conduct extensive experiments in eight real world networks by simulating the susceptible-infected-recovered (SIR) and susceptible-infected-susceptible (SIS) epidemic models which serve as ground truth identifiers of nodes spreading efficiency. Experimentally, we show that by exploring only the 20% of the network and using the degree centrality as well as the k-core measure, we are able to identify the influential spreaders with at least the same accuracy as in the full information case, namely, the case where we have access to the original graph and in that graph, we compute the centrality measures. Finally and more importantly, we present strong evidence that the degree centrality – the degree of nodes in the collected samples – is almost as accurate as the k-core values obtained from the original graph.

An interesting paper from 2017.

Five Russian GRU Officers and One Civilian Charged for Conspiring to Hack Ukrainian Government

It is the official release of the charge against Tenet and the Russian paymasters that was release a couple of weeks ago. For a good overview of the case, I recommend this article from the Columbia Journalism ReviewThe Tenet Media Incident

Undersøgelsen tager udgangspunkt i voksne minoritetsetniske personer med
opvækst i Danmark – dvs. personer der enten er født i Danmark eller kommet hertil
som børn (herefter betegnet som minoritetsetniske personer). Overordnet viser
besvarelserne i undersøgelsen, at over 8 ud af 10 minoritetsetniske personer angiver,
at de har oplevet diskrimination eller fordomme inden for det seneste år. Over 6 ud af
10 minoritetsetniske personer angiver, at de har oplevelser, man som udgangspunkt
kan karakterisere som ulovlig diskrimination. For mange er der ikke tale om en enkelt
hændelse, men gentagne negative oplevelser på tværs af bl.a. arbejdsmarkedet, i det
offentlige rum og i kontakten med myndigheder.

Lockdowns and Teen girl brains

There is currently some news going around that Covid lockdowns prematurely aged girls’ brains more than boys’

Adolescent girls who lived through Covid lockdowns experienced more rapid brain ageing than boys, according to data that suggests the social restrictions had a disproportionate impact on them.

MRI scans found evidence of premature brain ageing in both boys and girls, but girls’ brains appeared on average 4.2 years older than expected after lockdowns, compared with 1.4 years older for boys.

This certainly sounds like something we should be worried about, even if it is not clear what the effect of these differences are.

There are two things that should make you stop up, before getting two worried. It is the fact that the study is based on “MRI scans” and that it is about COVID political measures. MRI studies are rife with problems – as explained in Annual Research Review: Current limitations and future directions in MRI studies of child- and adult-onset developmental psychopathologie

The widespread use of magnetic resonance imaging (MRI) in the study of child- and adult-onset developmental psychopathologies has generated many investigations that have measured brain structure and function in vivo throughout development, often generating great excitement over our ability to visualize the living, developing brain using the attractive, even seductive images that these studies produce. Often lost in this excitement is the recognition that brain imaging generally, and MRI in particular, is simply a technology, one that does not fundamentally differ from any other technology, be it a blood test, a genotyping assay, a biochemical assay, or behavioral test. No technology alone can generate valid scientific findings. Rather, it is only technology coupled with a strong experimental design that can generate valid and reproducible findings that lead to new insights into the mechanisms of disease and therapeutic response

The subject the review focus on is not the one that the prematurely aged brains study fall under, but the same general problem exist.

And then there is the fact that the study is linked to COVID political measures. Any time this is the case, we have to stop up and be extra careful. There are a lot of biases related to this subject, both from the scientists and by the people reporting on the study.

Unsurprisingly this is also the case here. As epidemiologist Gideon Meyerowitz-Katz, the Health Nerd, explains:

Lockdowns Didn’t “Prematurely Age” Teen Girl’s Brains

Why the new viral study is extremely misleading

The study in question is a neurological examination of teen brains. The researchers put a bunch of adolescents aged 9-17 into MRIs before the pandemic, and then looked at their brains again a few years later. They used this data to look at what had happened to the brains in the interim using a variety of statistical techniques.

The Health Nerd goes through the study, explaining the setup and limits of the study. Unsurprisingly, it is a small study, and it is hard to make broad conclusions based on it. And when it comes to the effect of lockdowns?

Which brings us to an interesting point – what does any of this have to do with lockdowns?

Simple answer, really: nothing. The study does not, in any way, examine the effects of lockdown on teen brains.

Rather, the study shows that teen girls’ brains after the pandemic were different to the expected trends from brains before the pandemic. This could be caused by many things. Maybe the virus itself, which can cause some changes to brain chemistry, is to blame. Perhaps it was the global disruption brought about by a novel pandemic. Maybe the girls were more vulnerable than boys to things like relatives dying of COVID-19. We have no idea, because the authors didn’t do anything to investigate these myriad explanations. They don’t even report that the children in the study were present in Washington State for the lockdowns, nor whether they experienced similar lockdown impacts (i.e. school closures).

To make any inferences about lockdowns, the authors would’ve had to find some control group who’d had a different exposure to their intervention. Perhaps MRIs from kids in Florida, which had different COVID-19 restrictions, or a longitudinal sample from before the pandemic. These would all be inadequate samples for one reason or another, but they would’ve at least given some insight into whether lockdowns were associated with the cortical thinning seen in the research. As it stands, the study tells us nothing at all.

So, this is a somewhat doubtful study, which doesn’t tell us what is claimed about the study. The claims however are not sensational reporting by the press, but directly made by the scientists:

You can’t just blame the media here – the authors put the word “lockdown” into their study. It’s the second word of the title of their paper. Despite the paper having nothing to do with lockdowns.

This is, in a word, bad. Bad science. Poorly thought-through. Inadequate in a very serious way.

The Health Nerd  explains how such a paper could be published in PNAS.

Speaking of spices and science

Bharat B. Aggarwal was until recently the leading expert in the curative effects of curcumin.

Bharat B. Aggarwal is an Indian-American biochemist who worked at MD Anderson Cancer Center from 1989 to 2015. His research focused on potential anti-cancer effects and therapeutic applications of herbs and spices. Aggarwal was particularly drawn to curcumin, a non-toxic compound found in turmeric that has long been staple in Ayurvedic systems of medicine. He authored more than 120 articles about the compound from 1994 to 2020. These articles reported that curcumin had therapeutic potential for a variety of diseases, including various cancers, Alzheimer’s disease and, more recently, COVID-19. In his 2011 book Healing Spices: How to Use 50 Everyday and Exotic Spices to Boost Health and Beat Disease, Aggarwal recommends “taking a daily 500 mg curcumin supplement for general health”.

The above quote is from The King of Curcumin: a case study in the consequences of large-scale research fraud

As the title says, it turned out that Aggarwal committed research fraud

MD Anderson Cancer Center initially appeared to be fully on board with Aggarwal’s work. At one point, their website’s FAQ page recommended visitors buy curcumin wholesale from a company for which Aggarwal was a paid speaker (see “Spice Healer”, Scientific American). However, in 2012 (following observations of image manipulation raised by pseudonymous sleuth Juuichi Jigen), MD Anderson Cancer Center launched a research fraud probe against Aggarwal which eventually led to 30 of Aggarwal’s articles being retracted. Only some of these studies were about curcumin specifically, but most concerned similar natural products.

Retractions rarely number this high for a single author; according to the Retraction Watch leaderboard, only 26 other people have authored this many retracted studies. Aggarwal’s retracted articles feature dozens of instances of spliced Western blots and duplicated images, as well as several instances where mice were implanted with tumors exceeding volumes considered ethical. PubPeer commenters have noted irregularities in many publications beyond the 30 that have already been retracted. Aggarwal retired from M.D. Anderson in 2015, but has continued to author articles and appear at conferences.

I predict that more articles will be retracted in the future – not only because of Aggarwal being the author, but also because the field of study seems to be a magnet for frauds

Despite curcumin’s apparent lack of therapeutic promise, the volume of research produced on curcumin grows each year.  More than 2,000 studies involving the compound are published annually. Many of these studies bear signs of fraud and involvement of paper mills. As of 2020, the United States National Institutes of Health (NIH) has spent more than 150 million USD funding projects related to curcumin. Funding increased drastically in the 2007 fiscal year, shortly after Aggarwal began to publish in earnest about the compound and the same year he declared curcumin “the Indian solid gold”.

A obvious reason for this is the big money connected to this sort of fraudulent research

This proliferation of research on curcumin has fueled its popularity as a dietary supplement. Grand View Research estimated the global market for curcumin as a pharmaceutical to be around 30 million USD in 2020. Manufacturers are routinely scolded by the United States Food and Drug Administration for making false claims about the health effects of these supplements.

Spices don’t cure cancer

When you look at so-called alternative medicine, one of the remedies that is often pushed is using different spices against different disease, and quite frequently using spice as a cancer cure. Every time anyone have looked into any of these spices as a cure for something, they have of course turned out to be mostly worthless, though a few have turned out to have some effect.

This of course, leads to the claim that spice consumption is an ancient remedy against cancer. Unfortunately, a study from last year has shown that this is not likely to be the case.

No evidence that spice consumption is a cancer prevention mechanism in human populations by Antoine M Dujon et al

Abstract

Background

Why humans historically began to incorporate spices into their diets is still a matter of unresolved debate. For example, a recent study (Bromham et al. There is little evidence that spicy food in hot countries is an adaptation to reducing infection risk. Nat Hum Behav 2021;5:878–91.) did not support the most popular hypothesis that spice consumption was a practice favoured by selection in certain environments to reduce food poisoning, parasitic infections, and foodborne diseases.

Methods

Because several spices are known to have anticancer effects, we explored the hypothesis that natural selection and/or cultural evolution may have favoured spice consumption as an adaptive prophylactic response to reduce the burden of cancer pathology. We used linear models to investigate the potential relationship between age-standardized gastrointestinal cancer rates and spice consumption in 36 countries.

Results

Patterns of spice are not consistent with a cancer mitigation mechanism: the age-standardized rate of almost all gastrointestinal cancers was not related to spice consumption.

Conclusions

Direction other than foodborne pathogens and cancers should be explored to understand the health reasons, if any, why our ancestors developed a taste for spices.

I appropriate the effort to understand why spice was introduced into food in some parts of the world, and am looking forward to future research results

Computer models advancing science

Computer modeling has become a more and more important tool for science. We have seen it in Climatology for decades, as well as in a number of other fields. People who have a poor understanding of science, or who are trying to deny science, such as creationists and climate change deniers, will often claim that it isn’t really real science, but that is of course pure nonsense, as empirical evidence has demonstrated it again and again.

Now, there is a new great example of how a computer model is advancing our understanding of science. As ScienceDaily reports:

First hominin muscle reconstruction shows 3.2 million-year-old ‘Lucy’ could stand as erect as we can

A Cambridge University researcher has digitally reconstructed the missing soft tissue of an early human ancestor — or hominin — for the first time, revealing a capability to stand as erect as we do today.

Dr Ashleigh Wiseman has 3D-modelled the leg and pelvis muscles of the hominin Australopithecus afarensis using scans of ‘Lucy’: the famous fossil specimen discovered in Ethiopia in the mid-1970s.

Wiseman was able to use recently published open source data on the Lucy fossil to create a digital model of the 3.2 million-year-old hominin’s lower body muscle structure. The study is published in the journal Royal Society Open Science.

The research recreated 36 muscles in each leg, most of which were much larger in Lucy and occupied greater space in the legs compared to modern humans.

For example, major muscles in Lucy’s calves and thighs were over twice the size of those in modern humans, as we have a much higher fat to muscle ratio. Muscles made up 74% of the total mass in Lucy’s thigh, compared to just 50% in humans.

Paleoanthropologists agree that Lucy was bipedal, but disagree on how she walked. Some have argued that she moved in a crouching waddle, similar to chimpanzees — our common ancestor — when they walk on two legs. Others believe that her movement was closer to our own upright bipedalism.

Research in the last 20 years have seen a consensus begin to emerge for fully erect walking, and Wiseman’s work adds further weight to this. Lucy’s knee extensor muscles, and the leverage they would allow, confirm an ability to straighten the knee joints as much as a healthy person can today.

The paper can be found at the Royal Society Open Science: Three-dimensional volumetric muscle reconstruction of the Australopithecus afarensis pelvis and limb, with estimations of limb leverage

Abstract

To understand how an extinct species may have moved, we first need to reconstruct the missing soft tissues of the skeleton, which rarely preserve, with an understanding of segmental volume and muscular composition within the body. The Australopithecus afarensis specimen AL 288-1 is one of the most complete hominin skeletons. Despite 40+ years of research, the frequency and efficiency of bipedal movement in this specimen is still debated. Here, 36 muscles of the pelvis and lower limb were reconstructed using three-dimensional polygonal modelling, guided by imaging scan data and muscle scarring. Reconstructed muscle masses and configurations guided musculoskeletal modelling of the lower limb in comparison with a modern human. Results show that the moment arms of both species were comparable, hinting towards similar limb functionality. Moving forward, the polygonal muscle modelling approach has demonstrated promise for reconstructing the soft tissues of hominins and providing information on muscle configuration and space filling. This method demonstrates that volumetric reconstructions are required to know where space must be occupied by muscles and thus where lines of action might not be feasible due to interference with another muscle. This approach is effective for reconstructing muscle volumes in extinct hominins for which musculature is unknown.

The paper is an interesting read and in my opinion fairly accessible.

Science Vs limiting their output

I have listened to the Science Vs podcast for a while, but had somehow missed the fact that they had become exclusive to Spotify. This is not a good situation to be in for a podcast promoting the understanding of science, and the host/producer Wendy Zukerman and the editor Blythe Terrell have taken the consequences and are now limiting their output to shows that debunk stuff released on the Spotify platform

Zukerman, the host and executive producer for “Science Vs,” and Terrell, an editor for the science podcast, plan to limit their production on new episodes because they do not believe Spotify’s rules regarding misinformation go far enough.

“Until Spotify implements stronger methods to prevent the spread of misinformation on the platform, we will no longer be making new Science Vs episodes, except those intended to counteract misinformation being spread on Spotify,” they wrote in a letter to Ek, posted on Twitter on Monday.

“Science Vs,” which is exclusive to Spotify, looks at the science behind topics including pandemics.

They have already started doing this, with their latest episode Joe Rogan: The Malone Interview, which you can listen to here.

I applaud the principled stance that they have taken. You can find their twitter feed here.

Engadget have a few more details in Spotify’s ‘Science VS’ podcast will only fact-check misinformation being spread on Spotify
