Claire Higgins is reader in the department of bioengineering at Imperial College London. Her philosophy of science involves a problem-solving approach to research, where she models tissue growth, development, and repair using human skin and hair follicles. In their latest work, her research team transplanted hair follicles into human skin scars in an attempt to make that tissue healthy again. In t...

Scientists often refer to DNA as the blueprint of a cell. Whether the genetic material is single stranded or double stranded, linear or circular, organisms across the tree of life rely on their genomic blueprint for instructions on living, growing, and reproducing. Due to the amount of information carried by this blueprint, the size of the genome poses a biological dilemma; from humans to single-c...

Most mammals communicate vocally but humans are unique in their ability to communicate using spoken language. Humans are not born with an innate capacity to speak and understand language, but rather learn this skill as the brain develops. The complex interplay between neurobiology, genetics, and the environment shape vocal learning, but scientists do not understand the full extent to which each of...

Neurodegenerative disorders progressively impair a patient’s ability to function. Scientists expect the prevalence of these conditions to increase as the world’s population ages, and their clinical, genetic, and pathological heterogeneity complicates disease diagnosis and prognosis. The link between the immune system and neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS) is be...

Jennifer Munson is an associate professor in the Department of Biomedical Engineering and Mechanics at Virginia Tech. Her overarching research goal is to find new therapeutic targets in the tumor microenvironment by examining cancer from an onco-engineering perspective. Munson’s work combines fluid mechanics, neuroengineering, tissue engineering, and translational cancer research. She creates pers...

Jukka Koskela, a senior researcher at the Finnish Institute for Molecular Medicine, studies the complex genetics of various diseases, including rare diseases such as pulmonary fibrosis.

Despite the genetic basis of healthy aging, diet plays an important role in preventing inflammation, diabetes, and cognitive decline. Yet, healthy food choices are just part of the equation. Researchers are discovering how fasting can undo some of the metabolic damage imposed by the overindulgences of the typical Western diet. The human body may be wired to function optimally when exposed to perio...

Paul George, an assistant professor of neurology and neurological sciences at Stanford University, taps into the bioelectrical language of the injured brain to reawaken the healing potential of neural stem cells. Inspired by his patients, he looks for innovative strategies that may one day help patients recover from neurodegenerative diseases such as stroke. In this episode, Iris Kulbatski from Th...

As humans age, cells often acquire defects that lead to cancer. However, this fate may not be set in stone, as certain animals can circumvent the ravages of time and keep their cells healthy. In this episode, Niki Spahich from The Scientist’s Creative Services Team spoke with Vera Gorbunova, professor of biology at the University of Rochester and co-director of the Rochester Aging Research Center,...

To regulate protein production, cells use sophisticated strategies to keep RNA levels in check. This balance is especially important for hormone production, particularly aldosterone—the master regulator of blood pressure. When this balance is disrupted, the risk for disorders including hypertension and cardiovascular disease increases. In this episode, Niki Spahich from The Scientist’s Creative Se...

Welcome to Science Philosophy in a Flash, a mini podcast series produced by The Scientist’s Creative Services Team. In this series, we highlight researchers’ unique outlooks on what it means to be a scientist. Andrew Pelling, a professor at the University of Ottawa with appointments in the Departments of Physics and Biology, has a fresh approach to practicing science. He uses fruits and vegetables...

Sequencing the human genome in the early 2000s was an incredible feat, but the sequence was incomplete. Recently, a consortium of researchers published a telomere-to-telomere assembly of a complete human X chromosome. This accomplishment was made possible by advances in sequencing technology, allowing researchers to address the previous technical difficulties in analyzing challenging genomic regio...

Welcome to Science Philosophy in a Flash, a mini podcast series produced by The Scientist’s Creative Services Team. In this series, we highlight researchers’ unique outlooks on what it means to be a scientist. Aimée Parker, a research scientist at the Quadram Institute’s Gut Microbes and Health Research Programme, looks to the gut as the fountain of youth. She studies how rejuvenating the microbio...

Scientists have known for a long time that microbes can take up extracellular DNA fragments, and they have leveraged this transformation process to genetically modify bacteria in the lab. However, transformation is quite fickle and depends on creating the right balance of reagent concentrations and cellular conditions. How this process takes place outside of the petri dish, in more natural bacteri...

Staphylococcus aureus is a versatile pathogen that infects many areas of the body and has a number of strategies for avoiding the immune response. In this episode, Niki Spahich from The Scientist’s Creative Services team spoke with Anthony Richardson, an associate professor of microbiology and molecular genetics at the University of Pittsburgh, to learn how the bacterium fine-tunes its metabolism...

Viruses such as influenza and SARS-CoV-2 are constantly evolving to better infect their hosts.

To understand how the gut perceives and communicates information to the brain, scientists are taking a deeper look at the sensory cells lining the gut using cutting-edge techniques such as single-cell sequencing. While there are challenges and limitations to single-cell sequencing, researchers are becoming more adept at integrating the latest sequencing technology with complementary research techn...

In search for strategies to curb pandemics, scientists strive to understand how pathogens slip past the immune system and wreak havoc on the body. To achieve this goal, researchers study viral infection in models that mimic how different cell types interact with each other, the immune system, or the environment. Organ-on-a-chip models combine tissue engineering with microfluidics to replicate an o...

The cell is a fundamental unit of life that is capable of metabolism, synthesizing biological molecules, harnessing energy, and replicating. To understand how life works, researchers elucidate every detail related to cellular function and determine which processes are essential. With this information, scientists constructed the first synthetic minimal cell that encoded only the genes necessary for...

Epilepsy is one of the most common neurological conditions, affecting over 65 million individuals worldwide, and is characterized by recurrent, spontaneous, and uncontrollable seizures. Seizures commonly arise in the epileptic brain after a sudden burst in neurological activity. While many anti-epileptic drugs control seizures, one-third of patients with epilepsy fail to respond to them. Managing...

As neurodegenerative disorders such as Parkinson’s and Alzheimer’s disease wreak havoc on the brain and on our aging society, scientists race to identify factors that trigger neuronal demise and figure out how to stop them. Because neurons can’t be replaced, it is important to detect signs of stress in the brain early, before brain cells pass the point of no return. Scientists recently combined li...

As we know, far too well, infectious disease pandemics have the power to reshape the world. Thanks to the COVID-19 pandemic, we are observing pathogen evolution in real time as more variants arise and spread in waves. Another infamous infectious disease pandemic, simply called “the plague,” has popped up multiple times in history. How it changed the ancient world has intrigued both historians and...
