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 […]

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, […]

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 […]

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 […]

Distinct patterns of electrical activity in the sleeping brain may influence whether we remember or forget what we learned the previous day, according to a new study by UC San Francisco researchers. The scientists were able to influence how well rats learned a new skill by tweaking these brainwaves while […]
