Everyone faces stress occasionally, whether in school, at work, or during a global pandemic. However, some cannot cope as well as others. In a few cases, the cause is genetic. In humans, mutations in the OPHN1 gene cause a rare X-linked disease that includes poor stress tolerance. Cold Spring Harbor Laboratory (CSHL) […]

Myelodysplastic syndrome (MDS) is a disease, which can develop into acute leukaemia. It starts in the stem cells in the bone marrow, disturbing the maturing and differentiation process of blood cells. Now scientists at the University of Helsinki have demonstrated that artificial intelligence (AI) can effectively spot  genetic mutations in […]

The biggest advantage of Artificial Intelligence (AI) is its ability to analyse large amounts of data and categorize it in a way that is not immediately obvious to people. For example, now AI identified three new subtypes of multiple sclerosis (MS) in a recent UCL research. Scientists believe this will […]

Artificial Intelligence (AI) is a tool, which enables people to analyse huge pools of data very quickly and with high degree of accuracy. AI could speed up a lot of our scientific work. For example, researchers at Chalmers University of Technology, Sweden, have found that AI is able to generate […]

Humans are born with tens of thousands of hematopoietic stem cells (HSCs) that collectively ensure lifelong production of blood and immune cells that protect us from infections. HSCs can either duplicate to produce more stem cell progeny or differentiate to produce distinct immune cell lineages, an extremely critical decision that […]

Researchers at Stanford and KU Leuven have identified more than 70 genes that affect variation in both brain and facial structure. The genes don’t influence cognitive ability, further debunking beliefs that intelligence can be assessed by facial features. Even when you assume your best poker face, you reveal something about […]

Scientists at the University of Alberta have identified a mechanism for a protein that decreases the chance of developing Alzheimer’s disease—a discovery that highlights a new potential avenue for developing therapeutic treatments. The protein, called CD33, is known for its connection to Alzheimer’s disease susceptibility, but its exact role was […]

Cells from individuals with Major Depressive Disorder (MDD) were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study by a multidisciplinary team of UC San Francisco scientists, in collaboration with others.

A Penn Medicine patient with a genetic form of childhood blindness gained vision, which lasted more than a year, after receiving a single injection of an experimental RNA therapy into the eye. The clinical trial was conducted by researchers at the Scheie Eye Institute in the Perelman School of Medicine at the University […]

DNA sequencing has become so common, few realize how hard it is to even extract a single molecule of DNA from a biological sample. Research led by UC Riverside is making it easier to detect and capture DNA from fluid samples such as blood using a tiny glass tube and […]

For something we spend one-third of our lives doing, we still understand remarkably little about how sleep works — for example, why can some people sleep deeply through any disturbance, while others regularly toss and turn for hours each night? And why do we all seem to need a different […]

Curing cancer has been the dream of countless doctors and researchers over the decades. Yet some types of cancer, whether because they affect relatively few people or lack influential advocates, receive less attention and funding than others. A recent gift to Harvard Medical School is boosting efforts to understand and […]
