The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria Escherichia coli needs to slow its growth. Researchers used cryo-electron microscopy (cryo-EM) to capture the structures […]

Researchers have shown that the link between physical and mental illness is closer than previously thought. Certain changes in physical health, which are detectable in childhood, are linked with the development of mental illness in adulthood. The researchers, led by the University of Cambridge, used a sample of over 10,000 […]

Study shows how to determine the elusive motions of proteins that remain disordered. Researchers from the University of Cambridge, Google Research and the University of Milan have used machine learning techniques to predict how proteins, particularly those implicated in neurological diseases, completely change their shapes in a matter of microseconds. […]

Many patients with multiple myeloma, a type of blood cancer, eventually develop resistance to one treatment after another. That’s in part because cancer stem cells drive the disease — cells that continually self-renew. If a therapy can’t completely destroy these malignant stem cells, the cancer is likely to keep coming […]

New research from McMaster has found that psychiatric help for mothers with postpartum depression results in healthy changes in the brains of their babies. The study, published in the journal Depression and Anxiety this week, found treating mothers who had postpartum depression with cognitive behavioural therapy (CBT) not only helped […]

When they are activated to mount an immune response, T cells produce secretory proteins that help to manage their growth and other functions. But the intracellular pathways involved and molecular components that regulate this key process aren’t well understood. New research from a team of scientists at the University of […]

Biologists have long wondered how complex organisms contain a variety of dramatically different types of cells with specialized functions, even though all of those cells are genetically identical. New research reveals how proteins, called “pioneer transcription factors,” help turn on key genes that give cell types their unique properties and […]

Researchers at the National Institutes of Health have discovered a new genetic disorder characterized by developmental delays and malformations of the brain, heart and facial features. Named linkage-specific-deubiquitylation-deficiency-induced embryonic defects syndrome (LINKED), it is caused by a mutated version of the OTUD5 gene, which interferes with key molecular steps in embryo development. […]

Nowadays, the fashion trends and cosmetics industry promote fitness and “perfect” body types. Strict following of these “recommendations” may have harmful consequences. Social media do not help, promoting standards – to stay healthy and beautiful, measured in clothing sizes. Usually, there is no room for being “just average”. A larger […]

The United States is facing an epidemic of liver disease linked to obesity. Cases of nonalcoholic fatty liver have more than doubled in the past two decades, now affecting around one-quarter of the country’s population. The condition leads to inflammation and scarring in the liver, similar to that caused by […]

University of Alberta researchers have discovered a potential biomarker—the response of a particular reflex in the body dubbed the Hoffmann reflex—that would help surgeons deliver deep brain stimulation (DBS) more precisely and effectively to patients with advanced Parkinson’s disease. The work, led by U of A neurosurgeon Tejas Sankar, was recently published in […]

Several genetic mutations previously linked to breast cancer and included on commercial genetic tests, including direct-to-consumer tests, were found not to increase a woman’s risk of disease, according to a population study of more than 64,000 women published online in the New England Journal of Medicine from several institutions, including Penn Medicine. […]

The colons of African Americans and people of European descent age differently, new research reveals, helping explain racial disparities in colorectal cancer – cancer that killed beloved “Black Panther” star Chadwick Boseman at only 43. Scientists led by UVA Health’s Dr Li Li and Graham Casey, along with Matt Devall […]

Although prostate cancer is one the most common types of malignancy in men, diagnosis is typically made on the basis of the Prostate-specific antigen (PSA), with an accuracy as low as 30%. Given how unreliable PSA-based testing can often be, many patients require invasive biopsy which often leaves them with […]

A fundamental process by which cellular components are degraded is Autophagy. Defects in Autophagy pathways are strongly associated with multiple human diseases, including neurodegenerative disorders and cancer. Despite their importance, to date, a comprehensive characterization of the extent and selectivity for Autophagic degrades has remained largely uncharacterized. Researchers at Karolinska […]

Liverpool cancer researchers have contributed to important new findings of the positive role of androgens in breast cancer treatment, with immediate implications for women with oestrogen receptor-positive (ER-positive) advanced disease. ER-positive breast cancer is the most common type of breast cancer diagnosed today, accounting for around 75 out of every […]

One more piece of the puzzle has fallen into place behind a new drug whose anti-cancer potential was developed at the University of Alberta and is set to begin human trials this year, thanks to newly published research. “The results provide more justification and rationale for starting the clinical trial in […]

NineSigma, representing Suntory Global Innovation Center Ltd. (“Client”), which serves as the Suntory Group's basic research department, seeks technologies for making a minimally invasive assessment of cellular senescence in the human clinical setting. The Client has in mind biomarker-based assessment methods but welcomes proposals for a wide range of other approaches. Anti-ageing is […]

Researchers at the University of Adelaide have found new evidence about the positive role of androgens in breast cancer treatment with immediate implications for women with estrogen receptor-driven metastatic disease. Published in Nature Medicine, the international study conducted in collaboration with the Garvan Institute of Medical Research, looked at the […]

There is currently no cure for osteoarthritis, but a group of scientists believe they’ve discovered a method through which a simple knee injection could potentially stop the disease’s effects. These researchers showed that they could target a specific protein pathway in mice, put it into overdrive and halt cartilage degeneration […]

The abnormal immune system response that causes multiple sclerosis (MS) by attacking and damaging the central nervous system can be triggered by the lack of a specific fatty acid in fat tissue, according to a new Yale study. The finding suggests that dietary change might help treat some people with […]

Fisetin is perhaps the most intriguing of the first generation senolytic compounds, those capable of selectively destroying senescent cells in old tissues and thus producing rejuvenation to a meaningful degree. Senolytics have been demonstrated in animal studies to reverse many age-related conditions to a greater degree than any other approaches. […]

Imagine going to a surgeon to have a diseased or injured organ switched out for a fully functional, laboratory-grown replacement. This remains science fiction and not reality because researchers today struggle to organize cells into the complex 3D arrangements that our bodies can master on their own. There are two […]

A scientific study carried out by the Universidad Carlos III de Madrid (UC3M) and the Universidad Complutense de Madrid (UCM) has produced a mathematical description of the way in which a tumour invades the epithelial cells and automatically quantifies the progression of the tumour and the remaining cell islands after […]

Human genes have an impact on shaping our gut ecosystem according to new evidence from the international MIBioGen consortium study involving more than 18,000 people. The findings, led by the University Medical Center Groningen, Netherlands and involving researchers at the University of Bristol, are published today [18 January] in Nature […]

As the number of people who have fought off SARS-CoV-2 climbs ever higher, a critical question has grown in importance: How long will their immunity to the novel coronavirus last? A new Rockefeller study offers an encouraging answer, suggesting that those who recover from COVID-19 are protected against the virus […]

Targeted neuromodulation tailored to individual patients’ distinctive symptoms is an increasingly common way of correcting misfiring brain circuits in people with epilepsy or Parkinson’s disease. Now, scientists at UC San Francisco’s Dolby Family Center for Mood Disorders and Weill Institute for Neurosciences have demonstrated a novel personalized neuromodulation approach that – at least in […]

Anyone who has tried and failed to meditate knows that our minds are rarely still. But where do they roam? New research led by UC Berkeley has come up with a way to track the flow of our internal thought processes and signal whether our minds are focused, fixated or […]

Today's open access research paper is a reminder of one of the more direct mechanistic links between vascular aging and brain aging. Blood vessels stiffen with age, becoming progressively worse at the necessary task of contracting and relaxing in response to circumstances. This is in part due to cross-linking in […]

In addition to a skin rash, many eczema sufferers also experience chronic itching, but sometimes that itching can become torturous. Worse, antihistamines — the standard treatment for itching and allergy — often don’t help. New research from Washington University School of Medicine in St. Louis indicates that allergens in the environment often […]
