Piperlongumine, an extract of long peppers, was shown to be senolytic a few years ago. The compound is capable of selectively destroying senescent cells by sensitizing them to oxidative damage, provoking apoptosis. The accumulation of senescent cells is one of the causes of aging, and means of clearance are thus […]

Screening tools for autism spectrum disorder (ASD) often fail to identify ASD among children from low-income families and racial/ethnic minority groups, particularly when English is not the family’s primary language. A new visually-based tool may reduce these disparities at a pivotal point in children’s development. In Pediatrics, Zuleyha Cidav, David Mandell, and colleagues found […]

Head injury in the United States is common, with over 23 million adults age 40 or older reporting a history of head injury with loss of consciousness. Many head injuries can be caused by a host of different situations – from car and motorcycle accidents to sports injuries. What’s more, it […]

Anyone who has watched an infant’s eyes follow a dangling trinket dancing in front of them knows that babies are capable of paying attention with laser focus. But with large areas of their young brains still underdeveloped, how do they manage to do so? Using an approach pioneered at Yale […]

Nearly every older adult has prescribed a prescription drug that increased their risk of falling in 2017, according to new University at Buffalo research.

Scientists report on the structural and molecular factors governing the stability of a protein complex involved in DNA repair pathways in cells. The cells in our body are constantly fighting off the threat of cancer by repairing damaged DNA. In a new study, scientists from Tokyo University of Science investigate […]

Intake of a high-fat diet leads to an increased risk for obesity, type 2 diabetes, cardiovascular diseases and fatty liver. A study in mice from Karolinska Institutet shows that it is possible to eliminate the deleterious effects of a high-fat diet by lowering the levels of apolipoprotein CIII (apoCIII), a […]

New research by the University of Bristol as part of a team led by the University of Maryland (UMD) identifies age-related changes to DNA, revealing longevity-related differences among bat species. The study found that DNA from tissue samples can be used to accurately predict the age of bats in the […]

Patients with cancers of unknown origin greatly benefited from next-generation sequencing; widespread inherited cancer risk also suggests broad utility, a study finds. When standard cancer treatments don’t work, or if doctors can’t determine where a patient’s cancer originated, genomic sequencing can help pinpoint mutations in a tumor that might be […]

Mouse study focuses on signal from astrocytes to nerves. Researchers were able to enhance memory formation in mice by increasing a specific signal between astrocytes, one of the most numerous types of cell in the brain that occupy more space in the brain than nerve cells. Experts have long known […]

Researchers may have found the earliest changes that occur in seemingly healthy breast tissue long before any tumours appear, according to a new study published in the journal Nature Communications. The study, funded by Cancer Research UK, showed that before becoming cancerous, breast cells with the BRCA1 gene mutation undergo […]

Newly published research has revealed a close link between proteins associated with Alzheimer’s disease and age-related sight loss.

A gene therapy for chronic pain could offer a safer, non-addictive alternative to opioids. Researchers at the University of California San Diego developed the new therapy, which works by temporarily repressing a gene involved in sensing pain. It increased pain tolerance in mice, lowered their sensitivity to pain and provided […]

For certain blood cancers, such as acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), deciding whether patients need an aggressive treatment typically hinges on a set of lab tests to identify genetic changes. Some of these tests rely on technology that was invented more than 60 years ago and has […]

Eating is a dangerous business. Naturally occurring toxins in food and potentially harmful foodborne microbes can do a number on our intestines, leading to repeated minor injuries. In healthy people, such damage typically heals in a day or two. But in people with Crohn’s disease, the wounds fester, causing abdominal […]

In response to brain injury, neural stem cells cluster and migrate to the site of injury. The clustering is key – without it, the cells don’t travel. But what causes it? To investigate, Yale researchers created a 3-D model of the brain’s workings. The results of the study, led by […]

Scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced.
