Fresh insights could lead to new treatments for liver disease

The fight against liver disease could be helped by the discovery of cells that cause liver scarring. Scientists have identified new sub-types of cells that, when they interact, accelerate the scarring process in diseased livers. Experts hope that by understanding more how these cells behave, new treatments can be developed […]

Yale researchers develop way to help brain organoids thrive

Brain organoids created from human embryonic stem cells offer scientists a powerful way to study the developing brain in three dimensions. However, organoids need nutrients and oxygen carried in blood to thrive, just as a developing fetal brain does. Now Yale researchers have developed a method to induce growth of […]

Immune Cell Identity Crisis: What Makes a Liver Macrophage a Liver Macrophage?

Every tissue in the human body has an immune cell in it called a macrophage. Macrophages play important roles in the immune system’s initial response to bacteria, viruses and wounds. But beyond that, each tissue macrophage also has specialized functions, tuned to the needs of that particular tissue. For example, […]

Deafness-causing protein deficiency makes brain rewire itself, research suggests

The brains of people with congenital deafness may be rewiring themselves in ways that affect how those people learn, suggesting a need to develop new teaching techniques tailored toward those who have never been able to hear. Published in Nature Scientific Reports, the findings by an Oregon State University research […]

Study: Aggressive Breast Cancers Store Large Amounts of Energy, Which Enables It to Spread

Cancer cells – especially the more aggressive ones – seem to have an ability to change. It’s how they evade treatment and spread throughout the body. But how does a cancer cell get the energy it needs to do this? “We wondered if a cancer cell that wants to change its […]

Stanford chemist develop ‘infrared vision’ for cancer immunotherapy

Stanford chemists have developed a new deep-tissue imaging technique that can see beneath the skin of living subjects to illuminate buried tumors with unparalleled clarity. In a new study published in the issue of the journal Nature Biotechnology, the researchers demonstrate how their technique can be used to predict the response […]

Young adults of South Asian descent face higher risk of prediabetes, diabetes

Compared to long-term residents, immigrants to Canada have a 40 per cent higher risk of developing prediabetes, which is an early predictor of an individual’s likelihood of developing Type 2 diabetes and associated illnesses, like heart disease. Researchers from the University of Toronto’s Institute of Health Policy, Management and Evaluation in the […]

Early menopause may be a risk factor for cardiovascular disease

Even if we don’t think about it this way, we are still just a bunch of animals. We are mammals, connected to the laws of nature as tightly as the next species. And so our lives are divided into biological periods, which for women include menopause. However, for some women […]

Identifying a gene for canine night blindness

Creating an effective gene therapy for inherited diseases requires three key steps. First, scientists must identify and characterize the disease. Second, they must find the gene responsible. And finally, they must find a way to correct the impairment. Four years ago, a team from the University of Pennsylvania, in collaboration with […]
