A new study delves into the evolution and function of the human growth hormone receptor gene, and asks what forces in humanity's past may have driven changes to this vital piece of DNA.
h-index, g-index, i10 index, m-quotient, Journal Impact Factor, Altmetrics … it's long been an intractable issue plaguing the research community—how to assess the relative merits of research objectively across disciplines ...
When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. This is shown in a recent ...
Optical coherence tomography (OCT) is a non-invasive imaging method that can provide 3D information of biological samples. The first generation of OCT systems were based on time-domain imaging, using a mechanical scanning ...
As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?
Using long wavelength near-infrared light, scientists at UC Davis developed a label-free microscopy approach that achieves a unique combination of deep, high resolution, and minimally invasive brain imaging. The technique ...
Mammals see with their eyes, hear with their ears and smell with their nose. But which sense or organ allows them to orient themselves on their migrations, which sometimes go far beyond their local foraging areas and therefore ...
A quadruple fusion optical and ultrasound imaging system has been developed that allows diagnosis of eye conditions or tumors or to see the environment inside the body using a transparent ultrasound transducer.
Images provide information—what we can observe with our own eyes enables us to understand. Constantly expanding the field of perception into dimensions that are initially hidden from the naked eye, drives science forward. ...
A new kind of wearable health device would deliver real-time medical data to those with eye or mouth diseases, according to Huanyu 'Larry' Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of ...
