Scientists at the University of Alberta are part of a new research project to develop innovative precision diagnostics that could predict which men with prostate cancer are at risk of developing an aggressive form of the disease. The researchers will use germline sequencing (sequencing of the genes a person is […]

Researchers from Skoltech and their colleagues from Hadassah Medical Center have developed hybrid nanostructured particles that can be magnetically guided to the tumor, tracked by their fluorescence and pushed to release the drug on demand by ultrasound. This technology can help make cancer chemotherapy more targeted. The paper was published […]

A pilot human clinical trial conducted by researchers at Baylor College of Medicine reveals that supplementation with GlyNAC – a combination of glycine and N-acetylcysteine as precursors of the natural antioxidant glutathione – could improve many age-associated defects in older humans to improve muscle strength and cognition, and promote healthy […]

Good cholesterol, which is transported in HDLs (high-density lipoproteins), plays a key part in the prevention of atherosclerosis and thus the risk of cardiovascular disease. However, according to a new paper co-authored by researchers at Karolinska Institutet and published in the journal Circulation, the anti-inflammatory properties of HDLs could be […]

Histones are tiny proteins that bind to DNA and hold information that can help turn on or off individual genes. Researchers at Karolinska Institutet have developed a technique that makes it possible to examine how different versions of histones bind to the genome in tens of thousands of individual cells […]

Researchers uncover how cells control the physical state of embryonic tissues. In the earliest stage of life, animals undergo some of their most spectacular physical transformations. Once merely blobs of dividing cells, they begin to rearrange themselves into their more characteristic forms, be they fish, birds or humans. Understanding how […]

Researchers from Skoltech were part of a research consortium studying a case of vertical COVID-19 transmission from mother to her unborn child that resulted in major complications in the pregnancy, premature birth and death of the child. The consortium used a Skoltech-developed proteomics method to verify the diagnosis. The paper […]

Bat species include many that are long-lived for their size. Flying species in general are long lived; one can find many similarities in metabolism between bats and birds. It may be the case that the much higher metabolic rate of flying species requires improved mechanisms of cell resilience and cell […]

Medical researchers from Case Western Reserve University, New York University (NYU), and University Hospitals have been awarded a five-year, $3 million National Cancer Institute grant to develop and apply artificial intelligence (AI) tools for predicting which lung cancer patients will respond to immunotherapy. A unique aspect of the Case Western […]

Alzheimer’s disease is known for its slow attack on neurons crucial to memory and cognition.  But why are these particular neurons in ageing brains so susceptible to the disease’s ravages, while others remain resilient? In a new study published in the journal Alzheimer’s & Dementia, The Journal of the Alzheimer’s […]

Short pieces of DNA—jumping genes—can bounce from one place to another in our genomes. When too many DNA fragments move around, cancer, infertility, and other problems can arise. Cold Spring Harbor Laboratory (CSHL) Professor & HHMI Investigator Leemor Joshua-Tor and a research investigator in her lab, Jonathan Ipsaro, study how cells safeguard […]

If you’ve ever worked in a school, you know how sleepy some teens are. Why is that? Why aren’t they sleeping well when they are supposed to be sleeping? Well, there are some factors but one of them is probably social media. Scientists at the University of Glasgow have now […]

Naked mole-rats exhibit an unusually longevity, with a life span something like nine times as long as that of equivalently sized mammals. They are also highly resistant to cancer. This makes them an attractive subject for research into ways to treat aging and age-related disease. No one mechanism will be […]

In the fight against cancers, activating mutations in the RAS family of genes stand in the way of finding viable treatment options. Now, scientists at the University of Missouri and Yale University have discovered that one of these mutations — oncogenic RAS or RASV12 — is also responsible for the […]

A new study finds older adults who received positive airway pressure therapy prescribed for obstructive sleep apnea may be less likely to develop Alzheimer’s disease and other kinds of dementia. Researchers from Michigan Medicine’s Sleep Disorders Centers analyzed Medicare claims of more than 50,000 Medicare beneficiaries ages 65 and older who had been […]

Standard drugs remain the best first-line treatments for epilepsy, according to the results of two UK clinical trials led by the University of Liverpool. The Standard and New Antiepileptic Drugs (SANAD II) studies compared a range of antiepileptic drugs for how well they control seizures, their general tolerability and their […]

An analysis of electronic health records for 1.7 million Wisconsin patients revealed a variety of health problems newly associated with fragile X syndrome, the most common inherited cause of intellectual disability and autism, and may help identify cases years in advance of the typical clinical diagnosis. Researchers from the Waisman […]

Skoltech scientists and their colleagues have proposed a new human height inheritance model that accounts for the interaction between various factors that influence adult human height. The research was published in the European Journal of Human Genetics. Human height is a classical quantitative trait that depends on sex, genetics, and […]

Transient ischemia is the loss of blood supply to tissue followed by its restoration, leading to cell death, tissue damage, and harmful cell signaling. While the paper here is focused on connecting the significant ischemia of stroke with the later development of Alzheimer's disease, it is also the case that […]

A new national study will investigate the long-term effects of lung inflammation and scarring from COVID-19. The study, launched with £2 million of funding from UK Research and Innovation (UKRI), aims to develop treatment strategies and prevent disability. Many people recovering from COVID-19 suffer from long-term symptoms of lung damage, including breathlessness, […]

At a cost of $38 billion a year, an estimated 5.3 million people are living with a permanent disability related to traumatic brain injury in the United States today, according to the Centers for Disease Control and Prevention. The physical, mental and financial toll of a TBI can be enormous, but […]

People admitted to inpatient rehabilitation after hospitalization with COVID-19 showed deficits in mobility, cognition, speech, and swallowing at admission and improved significantly in all of these capabilities by the time they were discharged. However, a considerable number of patients exhibited residual deficits at discharge, highlighting the post-acute care needs of […]

On the surface, Parkinson’s disease — a neurodegenerative disorder — and melanoma — a type of skin cancer — do not appear to have much in common. However, for nearly 50 years, doctors have recognized that Parkinson’s disease patients are more likely to develop melanoma than the general population. Now, […]

In a genetics breakthrough that may help detect and conserve one of North America’s most endangered fish species, researchers from the U.S. Geological Survey’s Columbia Environmental Research Center and Southern Illinois University Carbondale recently produced offspring of endangered pallid sturgeon with DNA from only a single parent. These offspring are not […]
