System to image the human eye corrects for chromatic aberrations: Personalized method could help diagnose individual vision problems and enhance studies of color perception

Researchers report a new imaging system that cancels the chromatic optical aberrations present in a specific person’s eye, allowing for a more accurate assessment of vision and eye health. By taking pictures of the eye’s

Women’s gut microbiomes appear to mature earlier than men’s: Age also seems to be a factor, with younger guts more bacterially diverse (a good thing) than older ones

The human gut microbiome is a complex microbial ecosystem that plays an important role in our health. For example, these microbes — bacteria, viruses, fungi — help regulate metabolism, fend off infections, produce essential vitamins

New 3D printed microscope promising for medical diagnostics in developing countries: Inexpensive, robust and portable microscope provides high-resolution 3D images of cells

Researchers have used 3D printing to make an inexpensive and portable high-resolution microscope that is small and robust enough to use in the field or at the bedside. The high-resolution 3D images provided by the

Factors behind embryonic stem cell state

Embryonic stem cells (ESC) have the ability to self-renew, and, being pluripotent have the potential to create almost any cell type in the body. The embryonic stem cell state is established and maintained by multiple
