Murray ; Chun - Biu Li ; Akira Funahashi ; Tetsuya J. Kobayashi ; Viji M. Draviam ; Noriko Hiroi ; Naoki A. Irie ISBN: 9782889452132 Publication Date: 2017 With the emergence of Systems Biology, there is a greater realization that the whole behavior of a living system may not be simply described as the sum of its elements. To represent a living system using mathematical principles, practical quantities with units are required. Quantities are not only the bridge between mathematical description and biological observations; they often stand as essential elements similar to genome information in genetics. This important realization has greatly rejuvenated research in the area of Quantitative Biology. Because of the increased need for precise quantification, a new era of technological development has opened. For example, spatio-temporal high-resolution imaging enables us to track single molecule behavior in vivo. Clever artificial control of experimental conditions and molecular structures has expanded the variety of quantities that can be directly measured. In addition, improved computational power and novel algorithms for analyzing theoretical models have made it possible to investigate complex biological phenomena. This research topic is organized on two aspects of technological advances which are the backbone of Quantitative Biology: (i) visualization of biomolecules, their dynamics and function, and (ii) generic technologies of model optimization and numeric integration. We have also included articles highlighting the need for new quantitative approaches to solve some of the long-standing cell biology questions.

Here are some of the academic journals that USC Libraries subscribes to that are related to quantative biology:

• Cold Spring Harbor Symposia on Quantitative Biology Since 1933, major discoveries in biology--such as the structure of DNA, the genetic code, the polymerase chain reaction (PCR), and RNA interference (RNAi)--have been presented and debated at the Symposium held every summer at Cold Spring Harbor Laboratory in New York. Each Symposium focuses on a different and timely area of biological research and is attended by the leading figures in the field. The speakers are handpicked luminaries and rising stars who also publish a detailed discussion of the work they present in the annual Cold Spring Harbor Symposia on Quantitative Biology volume.

10 Life Science Trends to Watch in 2024

By Frances Gatta

From personalized medicine to lab automation to gene therapy, both established and emerging areas of innovation are set to help shape the future of the life sciences industry.

Let’s dive into ten of the biggest trending and emerging topics to watch in 2024.

1. Personalized medicine and cell therapies

Personalized medicine is a relatively new approach that aims to develop predictive, preventive, diagnostic, and therapeutic solutions more customized to each person’s physiological, environmental, and behavioral characteristics. The field has grown with the emergence of cutting-edge technologies enabling researchers to uncover individual differences in disease processes, such as DNA sequencing, multi-omics, 3D tumoroid culture systems , and wireless health monitoring.

Autologous cell therapy, which involves using a patient’s engineered cells as medicine, is major evidence of personalized medicine’s research, clinical, and commercial success. Capable of treating many intractable cancers, including multiple myeloma, cell therapy has rapidly risen in the pharmaceutical market and regulatory pipeline in the last decade. Five CAR-T cell therapies have received five FDA approval since its first in 2017. Many in the space are exploring emerging methods like NK cell and allogeneic therapies, while others explore closed, modular manufacturing systems for scale-up of existing therapies. The global cell therapy market was valued at $4.74 billion in 2023 and is expected to reach $5.89 billion in 2024.

Read more about emerging cell therapies like CAR-NK therapy

2. gene therapies.

Gene therapy , a ground-breaking field of molecular medicine predicted to impact healthcare profoundly, is seeing a renaissance after a rocky start 20 years ago. This is thanks to advances in genetics and bioengineering like CRISPR-Cas9 editing, nanoparticle biological delivery systems, and highly efficient adeno-associated virus (AAV) vector technologies.

Though applications are currently limited to research, gene therapies hold immense potential for treating diseases caused by autosomal recessive disorders such as sickle cell anemia, acquired genetic diseases such as cancer and cardiovascular diseases, and viral infections such as AIDS.

This rapidly evolving field has produced remarkable breakthroughs in recent times, with the latest being treating children with deafness caused by a mutated otoferlin gene with AAV1-hOTOF gene therapy. In 2023 , the FDA approved the first cell-based gene therapies for treating sickle cell disease and severe hemophilia A.

3. lab sustainability.

The life sciences industry continues to have a substantial environmental impact due to its heavy use of energy and resources. The pharmaceutical industry , in particular, is responsible for 4.4% of global emissions, and unaddressed, its carbon footprint is projected to triple by 2050. As advocates for a better world through science, researchers are often also passionate about mitigating climate change and its far-reaching impact s on human and ecosystem health. Where possible, they’re seeking to limit hazardous, consumable, and packaging waste; improve energy efficiency in the lab; and extend the life cycle of their tools before disposal or recycling.

In response, research organizations and industry members like Thermo Fisher Scientific are prioritizing scientific innovaiton and creating labeling systems to help scientists understand a product’s sustainability profile more transparently. Modern sustainable design approaches are paying off with more environmentally sustainable products , such as DynaGreen™ Protein A Magnetic Bead s, that can reduce environmental impact without sacrificing scientific quality.

4. de-extinction science and paleogenomics.

A few decades ago, the idea of assembling a genome with or otherwise extracting meaningful genetic information from samples like 19 th century museum specimens, Egyptian mummies, and prehistoric bones seemed like science fiction – as did concepts like “de-extinction” that would seek to bring long-gone species back to life for ecological purposes. For context, even in modern forensic science applications, bone samples of even 20 years old are some of the most difficult for reliable DNA analysis.

Scientists like Svante Pääbo, 2022 Nobel Laureate in Medicine or Physiology recognized for his pioneering work in sequencing the Neanderthal genome, and the arrival of next-generation sequencing (NGS) technologies has brought these once far-fetched ideas into exciting reality.

Today’s scientific instruments and technologies make it possible to prepare, purify, and analyze more delicate and degraded samples than ever before. Research teams have already sequenced and published the genomes of at least 8,000 ancient individuals . As the field continues to grow, so do the prospects of shedding new light on our evolutionary history, genetic factors for disease risk, and more.

Read more about advancements in ancient DNA sample analysis 

5. more complex, biologically relevant cancer research models with tumoroid culture.

More than 90% of potential anti-cancer drugs fail in clinical trials, often due to the heavy limitations of 2D pre-clinical models that rely on traditional immortal tumor lines. These models struggle to accurately replicate the complex environment and biological processes within real-life patient tumors, limiting their clinical translatability. 3D culture tumoroid models , on the other hand, are emerging as excellent alternatives that can more accurately reflect the physiological behaviors and characteristics of cancer cells, closing the gap between laboratory and clinical settings.

Tumoroids , also called tumor organoids or tumor-like organoids, are complex 3D culture models sourced from primary tumors obtained from patients. Tumoroid setups have been DIY for some time, with a steep learning curve and spotty reproducibility. But newer tools like the Gibco™ OncoPro™ Tumoroid Culture Medium Kit are making tumoroid systems more accessible and standardized between research groups. These biologically relevant cancer research models have big potential to accelerate strides in cancer drug development and personalized medicine.

Read more about advances in tumoroid culture systems

6. mrna-based therapeutics.

After decades of research, mRNA-based therapeutics came into the spotlight with the launch of mRNA-based SARS-CoV-19 vaccines and have proven themselves as a safe, easy-to-produce, targeted, versatile, and effective drug class.  mRNA-based therapy also shows promise in treating diseases currently difficult to treat, such as metabolic genetic diseases, cardiovascular diseases, infectious diseases, cerebrovascular diseases, and cancer.

The emergence of commercially successful mRNA-based therapies is expected to pave the way for a new generation of nucleic acid medicines.

7. lab automation.

Lab automation can improve the quality and reproducibility of results, support clinical translation in a closed-system environment, and improve researcher efficiency, speed, and productivity. New, exciting options are emerging fast – offering everything from GMP compliance to AI-powered analysis and all-in-one, hands-off workflow completion. Likewise, the benchtop footprint of advanced instruments are shrinking as materials and engineering technologies advance.

Automated tools and systems will be key to the clinical manufacturing future, expanding the field’s ability to both “fail fast” in R&D for processes like drug candidate screening and to scale up quickly on what works – potentially breaking the bottleneck for lifesaving therapies like mRNA vaccines, cell therapies, and more.

Guest Essay

The Long-Overlooked Molecule That Will Define a Generation of Science

By Thomas Cech

Dr. Cech is a biochemist and the author of the forthcoming book “The Catalyst: RNA and the Quest to Unlock Life’s Deepest Secrets,” from which this essay is adapted.

From E=mc² to splitting the atom to the invention of the transistor, the first half of the 20th century was dominated by breakthroughs in physics.

Then, in the early 1950s, biology began to nudge physics out of the scientific spotlight — and when I say “biology,” what I really mean is DNA. The momentous discovery of the DNA double helix in 1953 more or less ushered in a new era in science that culminated in the Human Genome Project, completed in 2003, which decoded all of our DNA into a biological blueprint of humankind.

DNA has received an immense amount of attention. And while the double helix was certainly groundbreaking in its time, the current generation of scientific history will be defined by a different (and, until recently, lesser-known) molecule — one that I believe will play an even bigger role in furthering our understanding of human life: RNA.

You may remember learning about RNA (ribonucleic acid) back in your high school biology class as the messenger that carries information stored in DNA to instruct the formation of proteins. Such messenger RNA, mRNA for short, recently entered the mainstream conversation thanks to the role they played in the Covid-19 vaccines. But RNA is much more than a messenger, as critical as that function may be.

Other types of RNA, called “noncoding” RNAs, are a tiny biological powerhouse that can help to treat and cure deadly diseases, unlock the potential of the human genome and solve one of the most enduring mysteries of science: explaining the origins of all life on our planet.

Though it is a linchpin of every living thing on Earth, RNA was misunderstood and underappreciated for decades — often dismissed as nothing more than a biochemical backup singer, slaving away in obscurity in the shadows of the diva, DNA. I know that firsthand: I was slaving away in obscurity on its behalf.

In the early 1980s, when I was much younger and most of the promise of RNA was still unimagined, I set up my lab at the University of Colorado, Boulder. After two years of false leads and frustration, my research group discovered that the RNA we’d been studying had catalytic power. This means that the RNA could cut and join biochemical bonds all by itself — the sort of activity that had been thought to be the sole purview of protein enzymes. This gave us a tantalizing glimpse at our deepest origins: If RNA could both hold information and orchestrate the assembly of molecules, it was very likely that the first living things to spring out of the primordial ooze were RNA-based organisms.

That breakthrough at my lab — along with independent observations of RNA catalysis by Sidney Altman at Yale — was recognized with a Nobel Prize in 1989. The attention generated by the prize helped lead to an efflorescence of research that continued to expand our idea of what RNA could do.

In recent years, our understanding of RNA has begun to advance even more rapidly. Since 2000, RNA-related breakthroughs have led to 11 Nobel Prizes. In the same period, the number of scientific journal articles and patents generated annually by RNA research has quadrupled. There are more than 400 RNA-based drugs in development, beyond the ones that are already in use. And in 2022 alone, more than $1 billion in private equity funds was invested in biotechnology start-ups to explore frontiers in RNA research.

What’s driving the RNA age is this molecule’s dazzling versatility. Yes, RNA can store genetic information, just like DNA. As a case in point, many of the viruses (from influenza to Ebola to SARS-CoV-2) that plague us don’t bother with DNA at all; their genes are made of RNA, which suits them perfectly well. But storing information is only the first chapter in RNA’s playbook.

Unlike DNA, RNA plays numerous active roles in living cells. It acts as an enzyme, splicing and dicing other RNA molecules or assembling proteins — the stuff of which all life is built — from amino acid building blocks. It keeps stem cells active and forestalls aging by building out the DNA at the ends of our chromosomes.

RNA discoveries have led to new therapies, such as the use of antisense RNA to help treat children afflicted with the devastating disease spinal muscular atrophy. The mRNA vaccines, which saved millions of lives during the Covid pandemic, are being reformulated to attack other diseases, including some cancers . RNA research may also be helping us rewrite the future; the genetic scissors that give CRISPR its breathtaking power to edit genes are guided to their sites of action by RNAs.

Although most scientists now agree on RNA's bright promise, we are still only beginning to unlock its potential. Consider, for instance, that some 75 percent of the human genome consists of dark matter that is copied into RNAs of unknown function. While some researchers have dismissed this dark matter as junk or noise, I expect it will be the source of even more exciting breakthroughs.

We don’t know yet how many of these possibilities will prove true. But if the past 40 years of research have taught me anything, it is never to underestimate this little molecule. The age of RNA is just getting started.

Thomas Cech is a biochemist at the University of Colorado, Boulder; a recipient of the Nobel Prize in Chemistry in 1989 for his work with RNA; and the author of “The Catalyst: RNA and the Quest to Unlock Life’s Deepest Secrets,” from which this essay is adapted.

Origins of 'Welsh dragons' finally exposed by experts

A large fossil discovery has helped shed light on the history of dinosaurs in Wales.

Until recently, the land of the dragon didn't have any dinosaurs. However, in the last ten years, several dinosaurs have been reported, but their life conditions were not well known. In a new study by a team from the University of Bristol and published in Proceedings of the Geologists' Association , important details have been revealed for the first time.

They found that early Welsh dinosaurs from over 200 million year ago lived on a tropical lowland beside the sea. Dinosaur trackways are known from Barry and other sites nearby, showing that dinosaurs had walked across the warm lowlands.

The discovery was made at Lavernock Point, close to Cardiff and Penarth, where the cliffs of dark-coloured shales and limestones document ancient shallow seas. At several levels, there are accumulations of bones, including the remains of fish, sharks, marine reptiles and occasionally, dinosaurs.

Former student of the Bristol MSc in Palaeobiology Owain Evans led the study. He explained: "The bone bed paints the picture of a tropical archipelago, which was subjected to frequent storms, that washed material from around the surrounding area, both in land and out at sea, into a tidal zone. This means that from just one fossil horizon, we can reconstruct a complex ecological system, with a diverse array of marine reptiles like ichthyosaurs, plesiosaurs and placodonts in the water, and dinosaurs on land.

"I had visited the coast at Penarth all my life, growing up in Cardiff, but never noticed the fossils. Then, the more I read, the more amazing it became. Local geologists had been collecting bones since the 1870s, and most of these are in the National Museum of Wales in Cardiff."

Cindy Howells, Curator of Palaeontology at the National Museum of Wales, adds: "The collections from Lavernock go all the way back to the 19 th century, with many sections of the bone bed being collected over the years. The presence of dinosaur fossils at the site ensure that it remains one of the most significant localities for palaeontology in Wales."

Two discoveries made by the team while conducting fieldwork at Lavernock were the fossilized remains of a placodont osteoderm, and a single coelacanth gular bone. Supervisor Dr Chris Duffin said: "The remains of coelacanths and placodonts are relatively rare in the UK, which makes these finds even more remarkable. These two fossils alone help build a broader picture of what the Rhaetian in the UK would have looked like."

Professor Michael Benton from Bristol's School of Earth Sciences, another project supervisor, adds: "The volume of dinosaur remains found at Lavernock is extremely exciting, and is a chance to study a complex, and often mysterious period in their evolutionary history. We have identified the remains of a large Plateosaurus like animal, along with several bones which likely belonged to a predatory theropod."

A significant section of the paper is dedicated to the abundant microfossils found at the site, which include fish teeth, scales and bone fragments. By examining thousands of specimens, the team were able to identify the key species in the shallow seas and work out the relative importance of each.

The origins of the Welsh dragons have been pinned down at last.

Evolution and dispersal of snakes across the Cretaceous-Paleogene mass extinction

Snakes are one of the most successful groups of living vertebrates, but the timing of their diversification is unclear. Combining molecular clocks, fossils, and biogeography, Klein et al. show that snakes experienced a diversification, and underwent dispersal, around the time of the end-Cretaceous mass extinction.

Researchers analyze prevalence, impact of ethical or religious barriers to providing medical aid in dying

by CU Anschutz Medical Campus

Recently published research led by the University of Colorado Anschutz Medical Campus examined the prevalence—and impact—of physicians' ethical or religious barriers to their involvement in medical aid in dying (MAiD), a multi-step process where a physician provides a terminally ill adult with decision-making capacity with a lethal dose of medication to end their life.

The research article , " Conscience-Based Barriers to Medical Aid in Dying: A Survey of Colorado Physicians ," was published this May in the Journal of General Internal Medicine. It shows that 26% of physician survey respondents reported large ethical and/or religious barriers to their involvement in MAiD.

Despite these barriers, the research suggests these conscience-based barriers do not appear to affect these physicians ' willingness to discuss medical aid in dying with their patients. However, they are much less likely to have any direct participation in it—being significantly less likely to serve as a consulting or attending physician—compared to physicians without these barriers.

Informing public policy

As legislators and health leaders across the nation continue to debate policies related to medical aid in dying, research like this is vital to making informed decisions.

"Medical aid in dying is under consideration in a number of states, and it comes up every legislative session. You cannot make policy around things that are not well understood, and so it was critical to gather data to better understand what's going on," says Mika Hamer, Ph.D., MPH, the first author on the paper and a post-doctoral research fellow with the CU Center for Bioethics and Humanities.

"It is important to look at the actual behaviors of physicians. This research offers essentially the first look into what is happening on the ground in a previously hidden and difficult-to-study population."

For Hillary Lum, MD, Ph.D., a co-author of the paper and associate professor in the CU Division of Geriatric Medicine, getting involved in this research was important to her as a geriatrician and palliative medicine physician, given that questions about MAiD may arise when caring for older adults with serious illnesses.

"Medical aid-in-dying was legalized in 2016 in Colorado, but physician experiences providing care for patients seeking MAiD was under-studied," Lum says.

A reason for the lack of data is because there are extensive protections in place for physician and patient privacy. As a result, the vast majority of data that exists are from qualitative studies or surveys of the general physician population.

"There is a long-standing debate around MAiD—the legality, the ethical appropriateness, the morality—and people have extremely strong opinions about it. But when we let those really strong opinions drive policy, rather than empirical data , we run the risk of implementing misguided policy that is more amenable to the cultural sentiment or social context at the time," Hamer says.

To gather data about this important issue, researchers used anonymized, aggregate information on the 554 patients known to have received a MAiD prescription in Colorado from 2017 to 2020 and then identified the clinical conditions most prominent in this patient population.

The research team then determined which physicians in Colorado were providing care to patients likely to qualify for MAiD based on their clinical conditions and sent them an anonymous survey regarding their willingness to provide MAiD and actual prior participation in MAiD. Ultimately, 300 physicians responded.

Since then, researchers have published several papers about the study, including: a scientific report about the research methodology; an analysis of physician's attitudes and experiences ; an examination of their perspectives on disclosure, presence, and eligibility ; and the use and influence of medical aid in dying service on physician experiences .

"We felt there was an opportunity to look at this untapped aspect of the survey research. We had a hunch that there was something about ethical or religious barriers that may be different than other types of barriers physicians faced, like lack of time or fear of stigma," Hamer says.

"We wanted to understand what these physicians have actually done when faced with these decisions, and we had a unique opportunity to measure that and lend some empirical data into what is a very contentious topic—but one that's really quite understudied as far as hard data goes," she adds.

Lum agrees with Hamer, saying, "In the absence of data, it's easy to make assumptions—either that there are many physicians who have a conscientious objection to MAiD, or that there are few."

"Thus, this study was important to actually measure the percentage of physicians who have a religious or ethical reason for not participating in MAiD activities," Lum adds.

What the research shows

Out of the 300 survey respondents, 26% of physicians likely to care for MAiD-eligible patients in Colorado reported large ethical and/or religious barriers to participating in MAiD activities.

The survey also shows physicians with a longer time in practice and those identifying as non-white were more likely to report these conscience-based barriers.

Hamer said she was surprised that the survey data shows the physicians with these conscience-based barriers are still willing to participate in some aspects of the MAiD process. Specifically, when comparing physicians with and without these barriers, there was no difference in ancillary participation, meaning having discussions about MAiD or referring patients to other providers.

However, there were significant differences regarding direct participation in MAiD. To be eligible for MAiD, a patient must have decision-making capacity and a prognosis of less than six months to live. This prognosis must be independently verified by two physicians—an attending and consulting physician.

The survey found that only 5% of physicians with conscience-based barriers had served as a MAiD consultant, as compared to 31% of physicians without conscience-based barriers. When it came to serving as a MAiD attending, no physicians with conscience-based barriers had served in this role compared to 21% of physicians without these barriers.

"Participation looks different for different people. As far as consulting or attending, which are much more active roles that may involve writing prescriptions or doing evaluations—that's where we start to see those barriers really show up in terms of changes in behavior," Hamer says.

Lum says, "I think this emphasizes the importance of the relationship between physicians and patients. Whether a physician is willing to discuss, refer, serve as a consulting physician, or serve as a MAID attending physician is likely to vary. And there may be different reasons and situations related to the individual patient."

Both Hamer and Lum noted that this study was limited in its sample size, highlighting the need for further research. With regard to conscience-based barriers, Hamer says it is important to distinguish that these "are not necessarily barriers to be overcome in the traditional sense of barriers."

"We really see this as a space where physicians need accommodation—not intervention to help change their mind around this barrier," Hamer says. "It calls for continued protection of physician rights to conscientiously object or not participate in a service to which they have deeply held, conflicting beliefs."

There is also a need to better understand what support systems and processes need to be in place in clinics or hospitals to help support those physicians who have religious or ethical barriers. For instance, perhaps a formal referral process could be created so that physicians with these barriers can be involved in the beginning stages of MAiD, but when it comes to the more active roles, there is an established team the patient can be referred to.

"We must have protections in place and processes to support these physicians while ensuring patients are able to get the care they desire," Hamer says. "It is something that needs to be considered especially as the legality of MAiD potentially expands. We need a balance between protecting physicians' rights and preserving patient access."
