Programmed cell death, also called apoptosis, is an important process in human biology as it removes unwanted and damaged cells from our bodies. This process…
They found that a tiny fragment of ribonucleic acid (RNA), a chemical cousin of DNA, prompts stem cells to mature into red blood cells. The researchers also…
Pediatric researchers have discovered a new biological pathway in which small segments of RNA, called microRNA, help protect red blood cells from injury caused…
The findings are published in the online edition of Nature Medicine by David A. Cheresh, PhD, professor of pathology in the UC San Diego School of Medicine and…
A study in the Aug. 1 issue of the journal Sleep suggests that a dose of extra sleep on the weekend may be good medicine for adults who repeatedly stay up too…
Scientists from the University of Groningen in The Netherlands successfully used a 'genome mining' approach to find and activate a group of genes in the…
Results show that at 2 to 4 weeks of age, the mean strength of a pulsatile air-jet stimulus that was required to induce arousal during quiet sleep was…
“In healthy people, nerves do not fire excessively in response to small stimuli. This function allows us to focus on what really matters. Nerve cells maintain…
One Chicago skyline is dazzling enough. Now imagine 15,000 of them.A Northwestern University research team has done just that — drawing 15,000 identical…
Researchers created a library of micromolded, hexagonally spaced elastomeric micropost arrays, one to a few microns high, on which they cultivated cells. The…
A new membrane developed at the University of Rochester's Laboratory for Laser Energetics blocks gas from flowing through it when one color of light is shined…
Differentiation is the process of stem cells morphing into other types of cells. Understanding it is key to developing future stem cell-based regenerative…
Researchers from Cornell University's Weill Institute for Cell and Molecular Biology have discovered how a protein called Mec1 plays the role of “guardian of…
In this time of global change, understanding the basics of animal behavior and environmental interactions is just as important as predicting and planning for…
Eating red and processed meats has been linked to an increased risk of developing several different types of cancer. Animal studies have identified a number of…
Using little more than PVC rings, a trashcan, and a scale, students can literally get a feel for soil water retention and field capacity, concepts that are…
