Getting to the Core of HIV Replication

HIV-1 viral capsid simulations on XSEDE-allocated Stampede2, Bridges, Darwin systems uncover nucleotide entry mechanism. Viruses lurk in the grey area between the living and the nonliving, according to scientists. Like living things, they replicate but they don't do it on their own. The HIV-1 virus, like all viruses, needs to […]

Reversing a genetic cause of poor stress responses in mice

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) […]

Artificial Intelligence can see genetic mutations in the cancer cells that escape the human eye

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 […]

Artificial Intelligence identified three types of multiple sclerosis

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 […]

Study reveals how long-term infection and inflammation impairs immune response as we age

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 […]

Face, brain development tightly linked, study finds

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 […]

U of A chemists discover how a plaque-fighting protein protects against Alzheimer’s

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 […]

Healthy sleep may rely on long-overlooked brain cells

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 […]

No Cancer Left Behind

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 […]
