Swimming through turbulent water is easier for schooling fish compared to solitary swimmers, according to a study published June 6th in the open-access journal PLOS Biology by Yangfan Zhang of Harvard University, Massachusetts, US, and colleagues.

Locomotion is key to many aspects of animal behavior, from reproduction to feeding to migration, and so many species have developed adaptations to make moving around more efficient. In this study, Zhang and colleagues propose the turbulent sheltering hypothesis, which suggests that traveling in schools allows fish to shield each other from disruptive water currents, thus making it easier to swim through rough waters.

To test this hypothesis, the researchers ran trials with giant danios (Devario aeqipinnatus), observing these fish swimming alone or in groups of eight in both turbulent and steadily flowing water. High-speed cameras allowed researchers to observe the movements of the fish as they swam, and a respirometer allowed for measurements of fish respiration rates and energy expenditure.

These trials revealed that schooling fish expended up to 79% less energy while swimming in turbulent water compared to solitary fish. Schooling fish also clustered more closely together in turbulent water compared to steady water, while solitary fish had to beat their tails much more vigorously to maintain the same speed in more turbulent currents.

These results lend support to the turbulence sheltering hypothesis, indicating that locomotion efficiency might be a driving factor behind the evolution of schooling behavior. This information is valuable for understanding fish ecology, fundamentals of hydrodynamics and it might also be applied to the design and maintenance of habitats meant to harbor protected fish species or to hinder invasive ones. The authors note that future studies might build off of these findings to explore energy dynamics of group movements in further aquatic or aerial animals.

The authors add, What is the function of schooling behaviour in fishes? We show that being in a school substantially reduces the energetic cost for fish swimming in a turbulent environment, compared to swimming alone, providing support for the hypothesis that schooling behaviour protects individual fish from the increased energetic cost associated with swimming in turbulence.

Man’s remains identified after nearly 40 years | Biology | kvoa.com – KVOA Tucson News

TUCSON (KVOA) - For nearly 40 years an Idaho man and his mother had no idea if their loved one was dead or alive.

The man had a suspicion and a DNA test proved his worst fears.

A DNA test proved that the man's suspicions were correct.

But, it took four decades to learn the man's fate.

They didn't know for four decades.

The remains no longer belong to John Doe they belong to John Leigh III who died in a fiery plane crash in August of 1984.

The crash site was not found until 13 years later by hikers in the Rincon Mountains. They took a picture and asked to remain anonymous.

They told News 4 "The site was very steep, brushy and difficult. The shot obviously depicts some of the wreckage among the brush."

News 4 spoke to John IV "I really want to hike up to the crash site like I've said before that's the official burial site, and I want to pay my respects up there if I can get there."

He was just 4 years old when his dad disappeared.

"It really doesn't affect me like it affects my mom, because I never knew him, and to me, the biggest part is that I know now that he didn't skip out of town and it gives me peace."

Dr. Bruce Anderson works for the Office of the Medical Examiners. He said there were the remains of four adult men who were on the plane. He had to exhume the remains when Susan Leigh and her son John IV wanted to know if their loved one John III was on that ill-fated flight.

He sent DNA samples from the bones to three different labs, but it was the California Department of Justice Missing Persons DNA Program that not only identified Leigh's DNA but the three others as well.

Anderson said, "It took a while for DNA technology to improve to where they could get DNA profiles, good quality DNA profiles, out of degraded bone like this."

Also found in the wreckage besides remains, several personal effects. such as aviator glasses, a BIC lighter, a briefcase lock, and a pocket knife.

AACR 2024 Plenary: New Insights Into Early Cancer Biology – American Association for Cancer Research (AACR)

Seventy percent of cancer-related deaths are from cancer types with no available screening options, underscoring the importance of detecting cancer early when it is more easily treated. The American Association for Cancer Research (AACR) Annual Meeting 2024, held April 5-10, kicked off its plenary program with a session on Discovery Science in Early Cancer Biology and Interception, which was chaired by Daniel De Carvalho, PhD, a professor at University of Toronto and researcher at the Princess Margaret Research Centre.

[Early cancer detection] is where we can have the biggest impact from cancer research on clinical care, De Carvalho said. He noted that novel early detection approaches will depend on understanding the molecular changes that occur as cells evolve from normal to precancer to cancer.

We really need to understand early cancer biology and figure out ways to use this for cancer interception, he said.

Just in time for the newly declared National Cancer Prevention and Early Detection Month, the session featured four presentations that explored the early changes underpinning cancer development and efforts to target these for cancer treatment.

In the first presentation, Margaret Goodell, PhD, FAACR, a professor at Baylor College of Medicine, discussed mechanisms that may drive clonal hematopoiesis, a state characterized by the outgrowth of genetically distinct populations of hematopoietic stem cells. Clonal hematopoiesis commonly occurs with aging and increases an individuals risk for several blood cancers.

Understanding how clonal hematopoiesis develops is key to identifying novel approaches to prevent this premalignant condition from progressing to cancer, Goodell noted.

In three separate vignettes, she shared distinct mechanisms underlying clonal hematopoiesis, including commonly occurring mutations in PPM1D, the gene that encodes the p53 suppressor protein WIP1. Goodell showed that these mutations inactivated DNA repair and cell death mechanisms and made cells more likely to proliferate with unresolved DNA damage, particularly after exposure to chemotherapy drugs. Consistent with these preclinical findings, blood samples from patients who had received chemotherapy were enriched for PPM1D-mutated cells.

Chemotherapy exposure also increased the occurrence of mutations in the chromatin regulator SRCAP, the focus of Goodells second vignette. In contrast to PPM1D mutations, the commonly occurring SRCAP mutations increased DNA repair by upregulating the expression of DNA damage genes through histone alterations. Goodell noted that, although mutations in PPM1D and SRCAP had contrasting effects on DNA repair, they both provided survival advantages to hematopoietic stem cellsa phenomenon that might be explained by different environmental contexts.

Finally, Goodell discussed mutations in DNMT3A, which she described as the most important tumor suppressor in the hematopoietic system. She explained that hematopoietic stem cells with DNMT3A mutations exhibit enhanced self-renewal and suggested that this may be due to the mutants epigenetic impacts.

Goodell proposed that these mechanistic insights could lay the foundation for future cancer interception efforts. In the long term, she said, we think there will be great opportunities for interventions if we can understand which mutations are particularly bad, in which contexts they arise, and how we can interfere with their functions.

Most breast cancers are diagnosed in individuals 55 years of age or older, and research presented by Kornelia Polyak, MD, PhD, FAACR, a professor at Harvard Medical School and Dana-Farber Cancer Institute, shed light on the cancer-promoting changes that occur with aging.

Using rat models, Polyak and colleagues discovered that aging was associated with dysregulated proliferation of mammary epithelial cells (from which most breast cancers arise), altered gene expression, changes to the proportion of certain immune cells, modified tissue states, and the decline of various cellular functions.

Among the genes whose expression increased with aging was midkine (MDK), a growth factor that has been implicated in cancer and other diseases. Polyak shared data demonstrating that MDK was upregulated with aging in rat mammary tissue, as well as in plasma samples from older individuals and in human breast cancers. Additionally, individuals under the age of 55 whose normal breast tissue had higher levels of MDK were found to have a greater five-year risk of breast cancer, and young patients whose breast cancers had high levels of MDK had lower disease-free survival rates.

Further experimentation revealed that MDK may impact breast cancer development by activating the tumor-promoting PI3K signaling pathway, repressing tumor suppressive pathways, and enhancing metabolic activityconsequences mediated by SREBF1, a regulator of cell metabolism.

Don Cleveland, PhD, FAACR, a professor at the UC San Diego School of Medicine, shared mechanistic insights into chromothripsis (chromosome shattering) and its contributions to cancer development. He demonstrated that abnormal chromosomes accumulate in micronuclei, where they undergo chromothripsis through the action of the N4BP2 nuclease. Shattered chromosome fragments remain near one another due to tethering by the DNA repair protein TOPBP1, and this proximity facilitates aberrant ligation of the chromosome fragments into circular DNAs that amplify the expression of certain oncogenes and drive drug resistance.

Separately, he proposed that Epstein-Barr virus (EBV) may promote cancer through a similar tethering action as shattered chromosome fragments. He showed that the viral protein EBNA1 becomes tethered to an EBV-like DNA sequence in chromosome 11, which leads to chromosome breakage and the separation of the MLL gene from the rest of chromosome 11. The MLL-containing DNA fragment enters micronuclei and undergoes chromothripsis, re-ligation, and amplification of MLL. This, in turn, inactivates the DNA repair protein ATM and may promote the formation of cancer. (MLL is a negative regulator of ATM.)

The accumulation of DNA damage can lead to cancer and, if left unresolved, trigger cell death. For this reason, many researchers are exploring inhibiting DNA repair as a potential approach to treat cancer. Michael Kastan, MD, PhD, FAACR, a professor at Duke University and executive director of Duke Cancer Institute, demonstrated the potential of an investigational chemical inhibitor of the DNA repair proteins ATM and DNA-PK to sensitize cells to radiation.

ATM and DNA-PK are signal transducers activated early in the response to DNA damage and regulate a multitude of downstream effector proteins that ultimately repair the damage or trigger cell death.

Kastan explained that ATM and DNA-PK are logical targets because 1) they are important regulators of DNA repair, 2) their activity is not essential to the survival of cells, and 3) cells that lack either protein remain sensitive to radiation.

He and colleagues identified XRD-0394, a novel dual inhibitor of ATM and DNA-PK, that could be delivered systemically. In preclinical models, XRD-0394 inhibited both proteins in a dose-dependent manner. Importantly, it led to cell death only in the presence of radiation, which allowed the drug to be delivered systemically without widespread toxicities.

Based on these preclinical data, Kastan and colleagues initiated a phase I clinical trial to evaluate the safety and pharmacokinetics of the drug in patients. The drug has not led to any dose-limiting toxicities thus far, and patient tumor samples indicate that the drug successfully inhibits ATM in patients. Kastan plans to explore combining XRD-0394 with various other therapies, such as immune checkpoint inhibitors, PARP inhibitors, and cytotoxic drugs.

Analytics for Spatial Biology: DNA and RNA Imaging – LCGC Chromatography Online

Gradient boosting machine (GBM) learning is applied to analyzing DNA and RNA images created using AI and multiple analytical techniques. AI and GBM hold promise for simplifying and standardizing discovery for spatial biology. During a lecture at the 2024 Analytica conference in Munich, Germany, several experts spoke about this technology.

To begin this session, Denis Schapiro, from the University Hospital Heidelberg and Heidelberg University in Germany, presented "From oncology to cardiology: Spatial omics technologies for topographic biomarker discovery," emphasized the development of the histoCAT software toolbox designed for highly multiplexed image analysis, particularly from imaging mass cytometry (IMC). Imaging mass cytometry (IMC) is a technique that displays the spatial distribution of proteins or other biomolecules within tissue samples. These images are generated by combining mass spectrometry using metal-tagged antibodies, enzymatic methods, or by using fluorescence spectroscopy. Schapiro introduced histoCAT's advanced machine learning (ML) approaches and its integration with the modular computational pipeline, MCMICRO, enabling proteomic and transcriptomic analysis across various spatial technologies. Additionally, Schapiro discussed the highly multiplexed tissue imaging (MITI) standard and a spatial power analysis framework to enhance experimental design strategies, demonstrated through data processing related to myocardial infarction.

The second talk by Ralf Jungmann, of LMU Munich and Max Planck Institute of Biochemistry in Germany, gave a lecture titled "From DNA Nanotechnology to Biomedical insight: Towards Single-Molecule Spatial Omics," outlined advancements in DNA-PAINT software for converting standard fluorescence microscopy into a spatial omics tool. The analytical toolkit used for spatial omics typically includes techniques such as imaging mass cytometry (IMC) and spatially resolved RNA sequencing (spatial transcriptomics). These methods enable the simultaneous measurement of molecular and spatial information within tissue samples, facilitating the study of cellular heterogeneity, interactions, and spatial organization in biological systems. Jungmann introduced improvements achieving sub-nanometer spatial resolution and spectrally unlimited multiplexing, along with strategies to increase imaging speeds in DNA-PAINT. Furthermore, he presented cell surface receptor quantification techniques and their potential for therapeutic applications.

In the third session talk, Manuel Liebeke, from the University of Kiel, presented, "Deciphering Metabolism in HostMicrobe Interactions with Mass Spectrometry Imaging and Microscopy," discussing the use of mass spectrometry imaging (MALDI-MSI) and spatial metabolomics fluorescence in situ hybridization (metaFISH). These methods are used to study hostmicrobe interactions by allowing direct and simultaneous mapping of diverse metabolites within biological tissues. Liebeke showcased metaFISH's ability to assign spatial distribution of metabolites to specific microbiome members at single-cell resolution, providing insights into metabolic interactions in dynamic environments. Through metaFISH, precise localization of bacteria, host cells, and associated metabolites in animal tissues was demonstrated, enhancing understanding of metabolic interactions.

The final presentation of this session was given by Martin Seifert, of 10X Genomics in Leiden, the Netherlands. The talk was titled, "New Possibilities for the Discovery of Disease Relevant Information. Gaining a new Picture of Biology with Single Cell and Spatial Analyses." This talk highlighted the integration of single-cell sequencing, spatial transcriptomics, and targeted in-situ analyses for disease tissues. Seifert emphasized their potential in elucidating molecular patterns crucial for understanding various disease processes, exemplified through data processing related to formalin-fixed paraffin-embedded (FFPE) cancer samples. The lecture highlighted the complementary nature between different analytical technologies, providing new insights into disease-relevant processes. Mass spectrometry (MS) is most often employed to analyze the proteome and metabolome of single cells.

Here’s what I teach my students about finding jobs in marine biology and conservation – Southern Fried Science

Our field is competitive, some job postings are confusing, and some career advice is contradictory or wrong. Heres an exercise I have my students perform that I hope can help you.

Graphic via Woods Hole Oceanographic Institution

Hardly a day goes by that I dont see a heartbreaking post from a prospective marine biologist in one of the professional Facebook groups. People are (at best) giving up on their dreams, and some even find themselves in serious financial trouble, or standed far from home. People report that they graduated without taking an optional class that they now realize they should have taken to get a job, or that they spent 5-8 years getting a Ph.D. only to learn that their dream job doesnt require one. People realize after spending years training for a job that it does not pay enough to support them and their family and that they have to pursue another career entirely. There are daily complaints from students and new graduates that the job market is complicated and confusing, or that the advice they received from mentors didnt help them.

I love my career, I hate seeing students upset, and I want to try and help people out a little. So with that in mind, here is an abbreviated version of the exercise that I have my students do in class to learn about the marine biology and conservation job market. Please note that while most of the principles here are broadly applicable, local conditions may vary in some countries, and not all of this will make sense outside of a USA context.

What general types of jobs are there?

Generally speaking, I find that lots of people are not always super clear on the difference between a marine biology job and an ocean conservation job. With the understanding that positions are increasingly interdisciplinary and these lines are often blurred, and the understanding that there are lots of jobs that dont fit neatly into any of these categories, heres a quick general description of what types of groups generally hire ocean scientists. This is very basic and does not begin to cover all the nuances out there, but many people dont even know this much, so lets start with the basics.

-Academia. Colleges and Universities are where most scientific research takes place. Relevant positions here include faculty positions, postdoctoral positions (which require a Ph.D.), graduate student positions (both to earn your Masters or your Ph.D.), and research technican/field technician positions. Jobs here are generally a mix of research and teaching.

-Government agencies. In the USA, there are jobs available in government agencies both at the Federal and state level (for coastal states). Government agencies employ research scientists as well as managers and regulators whose job it is to synthesize science into a conservation and management plan. Note that USAJobs.gov is the way to apply for (almost) all Federal jobs, and is possibly the worst website ever created by humanity, so you should seek out USAJobs specific advice.

-Environmental non-profit groups. If you want to do conservation as opposed to scientific research, this type of position is often the best opportunity. Environmental non-profits hire advocates and campaign leaders to try and persuade the public and/or government officials to help protect the ocean, and an understanding of marine biology can help here. These groups increasingly also hire scientific advisors whose job it is to advise their staff advocates, and even scientific researchers to perform research relevant to that groups goals (see above about blurry lines between positions).

-Aquariums, zoos, and environmental education centers. If you want to work with animals directly (to help take care of captive animals) or to talk about ocean science and conservation to the public (as a docent or environmental educator,) this may be the career path for you.

What should you look for in a job?

The reason that I dont like giving anything but the most general career advice on social media is that I dont know you very well. I dont know your hopes and dreams. I dont know what youre willing to compromise on vs. whats a dealbreaker for you. I dont know your familiy life, or your hobbies. So instead of telling you how to make a decision, Ill tell you how to find the information needed to make your own choices.

I have my students examine current job board postings (more on how to find these below), and I have them look at currently posted jobs even though theyre not actually applying yet. The reason for this is simple: the most effective way to learn what kinds of jobs are available, what theyd be like, and what they require is to examine what kinds of jobs are available, what theyd be like, and what they require.

I ask students to look for the following pieces of information in the job ads they find on job boards, and to reflect on them accordingly:

-Where would you be living if you took this job? Some jobs are possible to do fully remotely, some require moving. If youd have to move for this job, would you be living somewhere where you would be happy? When I talk about this on social media, some people flippantly reply that of course marine biology jobs are near the coast and students not willing to move there are lazy, but of course its more complicated than that. Maybe your partner has a great job where you currently live and cant move. Maybe you need to live near a family member who you help take care of. Lots of coastal states arent especially friendly to LGBTQ+ people or other minorities. Maybe your life isnt complete unless you can go ballroom dancing once a week with an active ballroom dancing club. Your reasons are your own, but you should consider them carefully before taking a job where you wouldnt be happy, because your job is not the only part of your life that matters.

-What would your day be like if you got this job? Look at the actual duties of the job, they may surprise you. To put it mildly, it is unlikely that youre going to find a job that consists entirely of SCUBA diving on coral reefs all day every day. Are those duties something youd enjoy doing? Would you feel challenged and valued? (Its also worth noting that a universal truth in most fields is that the higher up you go in a career, the more supervision and managerial/admin type tasks youll be doing).

-How much freedom would you have? Some people really love to just perform their assigned tasks with lots of guidance and supervision, some people prefer to have flexibility to let their creativity run wild. Most entry level jobs have relatively little flexibility, youre far more likely to be a proverbial cog in a machine than to be asked to help to design the machines structure and outputs.

-What kind of job security and opportunities for advancement are there? Some positions are explicitly temporary (seasonal field tech, maternity leave cover, one-year fellowship, etc.) It may not make sense for you to move halfway around the world for a six month job with no possibility of extension.

-What skills or degrees does the job require? If the job does not require a Ph.D. and you could see yourself being happy doing this job (or ones like it) your whole career, it may not be worthwhile to get a Ph.D. If the job requires a Masters, you should probably plan on getting a Masters to do this job or one like it. If the job explicitly requires a technical skill like using ARCGIS or Python or MARXAN or rescue diver certification or something, you should strongly consider trying to learn those skills through an elective course while youre still a student. You should be aware of the difference between required skills and desired skills, as one is, well, required. If a job ad lists 10 desired skills and you dont have any of those skills, youre probably not a strong candidate for that position, but if you have 2 or 3, Id encourage you to apply because its likely that no one has all 10 and the people posting the job ad know that.

-What does the job pay? None of us pursue this career to get rich, but weve all got bills to pay and some of us have families to support. If you cannot survive on the provided salary and cant afford to take that job and need to consider another career path, its probably best to learn that now rather than after youve spent years pursuing a stressful and technical graduate degree. Lots of jobs dont post their salary, which is bad, because they should. But you can often find a similar job that does post a salary and assume itd be fairly similar. And salary commensurate with experience is not a great sign if you are looking for your first job and therefore dont have very much experience yet.

Discussion with students

Students are asked to look at lots of different types of jobs, but specifically to find one that looks like a dream job for them, one that looks miserable to them, and one surprising one that they didnt know was a job. After I have students look for jobs and record all of the information above, which can be done individually or in small groups depending on your class size, I bring everyone back together for a discussion.

Students are asked to share jobs they found and relevant info about those jobs. Students are asked to discuss if anything surprised them. Students are asked to think about if their current degree program provides them with the types of skills needed for these jobs, or if a new class or program is needed. And finally, students can ask questions.

Jobs boards

There are many marine biology jobs boards, but here are the ones I use for my course. It is likely that you will be able to find most currently posted jobs by examining and comparing these three. And be sure to check back reguarly, as now jobs are added weekly!

SevenSeas ocean jobs

Florida SeaGrants Facebook page (weekly job postings)

Conclusions

If youre a student or prospective student interested in marine biology as a career, Id encourage you to try this exercise. If youre teaching students, Id encourage you to incorporate some version of this into your course or lab meetings. Anyone is free to modify this however you like, I just ask that you let me know if you find a way that works better!

I cant help to create more jobs or better paying jobs or jobs in different places, but I hope that Ive helped to clear up some of the confusing parts of the marine biology and conservation job market.

Happy job hunting!

Biology, not technology, will save the planet | Vashon-Maury Island Beachcomber – Vashon-Maury Island Beachcomber

Regenerating Life offers a different, challenging, yet hopeful message about the climate crisis.

By Rondi Lightmark April 11, 2024 1:30 am

Regenerating Life by director John Feldman is a cant-miss film that offers a different, challenging, yet hopeful message about the climate crisis.

Consider this: what if the entire climate conversation about CO2 emissions and fossil fuels is a dangerous distraction from the real reason our planet is dying? What if rising CO2 levels and global warming trends are not causes, but symptoms of ecological loss?

We have lots of evidence every day about whats gone wrong the dying of ecosystems, plant and animal extinctions, fires, droughts and floods, melting glaciers, poisoned air. But Regenerating Life says we are missing the why. The story of excess greenhouse gases in the atmosphere is only one part of the picture.

The bigger view includes the countless relationships in nature that have been all but severed as a result of centuries of mismanagement of our natural resources because of human ignorance and greed.

Even as we seem to be standing on the brink of extinction, amazing revelations about the systems of the Earth are appearing: growing awareness of the symbiotic relationships between plankton and whales in the oceans, ruminants and grasslands, beaver and watersheds, trees and salmon in the Pacific Northwest, how the moisture content of soil and the transpiration of trees influences weather, how microbes are the workhorses of all life processes.

Weve been stuck in a limited narrative, bowing to chemistry and technology, discounting biology and natures intricate wisdom.

Regenerating Life takes on this challenge in three parts. Part one is titled Water Cools the Planet. Even though water vapor is the biggest greenhouse gas of all, water is not mentioned at all in discussions about emissions. Yet its role in both the biology and the hydrology of the planet is the basis of all life, and there is no subject more important to grasp.

Much of our current global turmoil is a direct result of the disappearance of water in countries all over the globe, from the war that began in Syria because of unrelenting drought, to the turmoil along our southern border.

Part two is Life Sustains the Planet. Nature knows best how to heal and manage life on the planet if we can just get out of the way. This part presents a biologically focused argument with inspiring examples of how this can be accomplished through ecological restoration even on vast areas of land in as little as 20 years. The big takeaway is that protecting and nurturing good soil will help balance solar radiation in and out from the planet.

Part three, Small Farms Feed the World, presents a great reason for valuing our Vashon farmers. This section advocates for nurturing small, local farming communities (by which most global food is already grown, more productively than corporate farms). An examination of the failures of the Green Revolution in Africa, the corporate push for growing crop monocultures, and genetic ownership of seed varieties is eloquently discussed by environmental activist Vandana Shiva, who has led the farmers resistance movement in India.

The Sorcerors Apprentice is a well-known poem by Johann Wolfgang von Goethe. Written in 1797, its about the chaos created when an old sorcerer leaves his workshop with his apprentice in charge.

The apprentice tries out some magic to enchant a broom to do his fetching-water work for him, but the shop is flooded when he realizes he does not know how to stop the spell. Its a fitting example of the hubris exhibited by those searching for technological solutions to the climate crisis from capturing carbon emissions and burying them underground, to sending solar shields into space, to creating fake food to feed the masses.

By contrast, John Feldmans film is a compelling and powerful lesson that nature can help us solve our climate problems if we give her a chance.

Regenerating Life, sponsored by The Whole Vashon Project, will be shown at 6 p.m. on Tuesday, April 16. Donations are welcome at the door.

Rondi Lightmark is the founder of The Whole Vashon Project. To find out more about the organization, and get involved, visit wholevashonproject.com.
