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 […]
