Apr. 24, 2015 — Scientists have discover that certain cell structures, the centrioles, could act as information carriers throughout cell generations. The discovery raises the possibility that transmission of ... read more

Apr. 24, 2015 — Researchers have discovered that the signalling route - a cascade activation of several molecules - triggered by the ATM protein regulates DNA repair during the production of spermatocytes by ... read more

Messenger RNA-Associated Protein Drives Multiple Paths in T-Cell Development

Apr. 21, 2015 — A lab studies how splicing occurs in T cells and how it is regulated by multiple proteins. This study describes a cascade of events that may explain changes in gene expression that occur during the ... read more

Apr. 21, 2015 — Nerve cells come in very different shapes. Researchers now reveal why, in insects, the cell body is usually located at the end of a separate extension. Using mathematical models, they show that this ... read more

Apr. 21, 2015 — Sweet potatoes from all over the world naturally contain genes from the bacterium Agrobacterium, researchers report. Sweet potato is one of the most important food crops for human consumption in the ... read more

Apr. 20, 2015 — Researchers have described the first known demonstration of 3-D cell imaging using picosecond ultrasonics, and show that picosecond ultrasonics can achieve micron resolution of single cells, imaging ... read more

Importance of 'Self-DNA' for Maintaining Diversity Among Species

Apr. 20, 2015 — In natural plant communities, diversity is maintained by limits set on each plant by itself. This involves a detrimental effect of self-DNA -- DNA from the same species released during decomposition ... read more

Oral Milk Thistle Extract Stops Colorectal Cancer Stem Cells from Growing Tumors

Apr. 20, 2015 — A new study shows that orally administering the chemical silibinin, purified from milk thistle, slows the ability of colorectal cancer stem cells to grow the disease. When stem cells from tumors ... read more

Bioenergy: Genetics of Wood Formation

Apr. 17, 2015 — To begin to understand poplar growth, a possible bioenergy crop, scientists built a robust high-throughput pipeline for studying the hierarchy of genetic regulation of wood formation using ... read more

New Mouse Model for the Study of Neurofibromatosis

Apr. 16, 2015 — New mouse models for the study of principal malignant tumor associated with neurofibromatosis type 1 have been developed by researchers. Neurofibromatosis are disorders of the nervous system that ... read more

Apr. 16, 2015 — Scientists have discovered a way to make trees grow bigger and faster, which could increase supplies of renewable resources and help trees cope with the effects of climate ... read more

How Salmonella Survives the Macrophage's Acid Attack

Apr. 14, 2015 — New research reveals that Salmonella fights acid with acid, by lowering the pH of its own interior in response to the acidification of the Salmonella-containing compartment by the macrophage, and by ... read more

Toward a Gene Expression Atlas for an Entire Brain

Apr. 14, 2015 — Researchers who study how genes are expressed across a given tissue can now examine thousands of genes at once at cellular resolution, thanks to new methods. The new techniques can be applied to a ... read more

Cell Division Research Expected to Lead to Containment of Cancer Cells and Regenerative Medical Treatments

Apr. 13, 2015 — All organisms grow and develop through the regenerative ability of cell division. An indispensable ability for all living beings, it can be said that life is defined by this process. Now, for the ... read more

Apr. 13, 2015 — It may come as a bit of a surprise to learn that bacteria have an immune system -- in their case to fight off invasive viruses called phages. And like any immune system -- from single-celled to human ... read more

Apr. 13, 2015 — Scientists get mouse heart cells to take a step backwards so they can be ... read more

Microbes Disprove Long-Held Assumption That All Organisms Share a Common Vocabulary

Apr. 10, 2015 — Some microorganisms found in nature and not grown in the laboratory reinterpret the instructions coded into their DNA. Short segments of DNA that signal other organisms to stop adding building blocks ... read more

Apr. 9, 2015 — Although serotonin is well known as a brain neurotransmitter, it is estimated that 90 percent of the body's serotonin is made in the digestive tract. In fact, altered levels of this peripheral ... read more

Apr. 9, 2015 — A plant's roots grow and spread into the soil, taking up necessary water and minerals. The tip of a plant's root is a place of active cell division followed by cell elongation, with ... read more

Apr. 9, 2015 — Interfering with the replication of the Ebola virus can stop the virus in its tracks, a new study shows. The discovery opens the door to finding more effective treatments. The Ebola outbreak that ... read more
