Nutrition scientist  Maryam Hamidi, PhD, conducted research recently which required her to repeatedly stay awake from 8 a.m. until 5 a.m. the next day. As part of the study, she also needed to keep supplies of both healthy and unhealthy snacks stacked in her office. Then, somewhere along the line, […]

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 […]

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, […]

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 […]

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 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 […]

Many scientists spend their lives conducting tests on a single gene but, in their quest to develop a drug that will repair injured spinal cords, researchers at The Miami Project to Cure Paralysis are testing thousands of genes in hundreds of thousands of nerve cells in any given week. In […]

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 […]

A triple drug combination has been used to extend the lifespan of fruit flies by 48 percent in a new study led by the Max Planck Institute for Biology of Ageing in Cologne, Germany, and the UCL. The three drugs are all already in use as medical treatments: lithium as […]

Vaccines made from RNA hold great potential as a way to treat cancer or prevent a variety of infectious diseases. Many biotech companies are now working on such vaccines, and a few have gone into clinical trials. One of the challenges to creating RNA vaccines is making sure that the […]

Science may be inching closer to thwarting obesity, heart disease and Type 2 diabetes, as Cornell biochemists have uncovered a key step in how the human body metabolizes sugar, according to new research published in the Journal of Biological Chemistry. Martha S. Field, assistant professor of nutritional sciences, has further […]

How do you repair a damaged heart? With love? Gifts of candy and flowers? Romantic actions? Well, no. A good way to repair a damaged heart is to patch it. Scientists from the University of New South Wales now demonstrated that you can patch the heart with a 3D printer, […]
