Animal Without Synapses Feeds by External Digestion Using Global, Local Cellular Control

Sep. 2, 2015 — A multicellular marine animal without organs, Trichoplax's feeding behavior may include cellular coordination, resulting in external food ... read more

Aug. 31, 2015 — From 1952, DNA was sequenced, modified and extensively studied, but no technique was able to produce clear direct images of DNA. Now, researchers have developed a new technique to produce a direct ... read more

Aug. 28, 2015 — A closer look at how honey bee colonies determine which larvae will serve as workers and which will become queens reveals that a plant chemical, p-coumaric acid, plays a key role in the bees' ... read more

Aug. 28, 2015 — In all organisms, water's pH has a profound effect. Because the interaction of carbon dioxide and water explains the natural acidity of water and all accompanying reactions, it is considered a ... read more

Aug. 28, 2015 — Viruses are able to redirect the functioning of cells in order to infect them. Inspired by their mode of action, scientists have designed a "chemical virus" that can cross the double lipid ... read more

Aug. 28, 2015 — Researchers have for the first time created and used a nanoscale vehicle made of DNA to deliver a CRISPR-Cas9 gene-editing tool into cells in both cell culture and an animal ... read more

Aug. 28, 2015 — Scientists have predicted how biological circuits generate rhythms and control their robustness, utilizing mathematical modeling based on differential equations and stochastic parameter ... read more

Aug. 28, 2015 — A growing, dividing cell uses most of its energy store to make its "protein factories," the ribosomes. An important player in their "assembly" is the exosome, a molecular ... read more

Aug. 28, 2015 — Nuclear pores in the nuclear membrane do not only control the transport of molecules into and out of the nucleus but also play an important role in gene expression. Researchers have deciphered a ... read more

Aug. 28, 2015 — Scientists have identified chemosensory proteins (CSPs) that play important roles in communications between worker ants. CSPs may represent a starting point for elucidation of the molecular ... read more

Aug. 27, 2015 — The fungus Cryptococcus causes meningitis, a brain disease that kills about 1 million people each year. It's difficult to treat because fungi are genetically quite similar to humans, so ... read more

Aug. 27, 2015 — Biochemists have solved the architecture of the nuclear pore complex's complicated inner ring, a subcomplex that is central to the cellular machine's ability to serve as a barrier and ... read more

Scientists Identify Possible Key in Virus, Cancer Research

Aug. 27, 2015 — Scientists have uncovered a viral protein in the cell that inhibits the major DNA sensor and thus the body's response to viral infection, suggesting that this cellular pathway could be ... read more

Aug. 27, 2015 — Scientists create a biological circuit by programming bacteria to alter gene expression in an entire population. They have created a biological equivalent to a computer circuit that involves multiple ... read more

Aug. 27, 2015 — Scientists can now watch dynamic biological processes with unprecedented clarity in living cells using new imaging techniques. The new methods dramatically improve on the spatial resolution provided ... read more

HIV Particles Do Not Cause AIDS, Our Own Immune Cells Do

Aug. 27, 2015 — Scientists have discovered that HIV does not cause AIDS by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. In a new ... read more

Aug. 27, 2015 — RNA can be translated into protein or transformed into gene-regulating molecules. A newly discovered 'reader' protein recognizes a chemical instruction tag affixed to RNA, an important step ... read more

Aug. 27, 2015 — Researchers have evidence in support of a clearly defined depth limit for deep-sea fishing in Europe. The findings come just as the European Union considers controversial new legislation to manage ... read more

Mammary Gland Is Shaped by Adaptive Immune System During Development

Aug. 27, 2015 — In experiments with mouse tissue, researchers have discovered that the adaptive immune system, generally associated with fighting infections, plays an active role in guiding the normal development of ... read more

Getting a Picture of the Molecules in a Cell in Just Minutes

Aug. 27, 2015 — Scientists can now take a peek into a single plant cell and -- within minutes -- get a view of the small molecules, including metabolites, hormones, nutrients, and lipids, inside ... read more
