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

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

How Dynamin Mediates Membrane Constriction and Scission

Aug. 27, 2015 — Cells continually form membrane vesicles that are released into the cell. If this vital process is disturbed, nerve cells, for example, cannot communicate with each other. The protein molecule ... read more

Aug. 27, 2015 — Cell mechanics are considerably more complex than previously thought and may affect cell structures at various ... read more

Aug. 27, 2015 — Researchers demonstrate how gram-negative bacteria deliver toxins to kill neighboring ... read more

Paralysis: Primates Recover Better Than Rodents

Aug. 26, 2015 — Monkeys and humans exhibit greater motor recovery than rats after similar spinal cord injury, according to a new ... read more

Aug. 26, 2015 — New insight into methanotrophs, bacteria that can oxidise methane, may help us develop an array of biotechnological applications that exploit methane and protect our environment from this potent ... read more

Aug. 26, 2015 — Researchers have for the first time developed a method to precisely control embryonic stem cell differentiation with beams of light, enabling them to be transformed into neurons in response to a ... read more

Aug. 26, 2015 — Could the sperm harpoon the egg to facilitate fertilization? That’s the intriguing possibility raised by the discovery that a protein within the head of the sperm forms spiky filaments, suggesting ... read more

Algorithm Helps Identify Elusive Genes That Express Like Clockwork

Aug. 25, 2015 — An algorithm is giving scientists a new way to identify the dynamics of oscillatory genes, which play an essential role in development functions like cell division, circadian rhythms and limb ... read more

Batting Practice in the Genome

Aug. 25, 2015 — In the biochemical game of genetics, it was thought that the proteins controlling gene regulation in animals were either spectators or players. But scientists have now found that spectator proteins ... read more

Adaptive Mutation Mechanism May Explain Some Forms of Antibiotic Resistance

Aug. 25, 2015 — Evolutionary theory says mutations are blind and occur randomly. But in the phenomenon of adaptive mutation, cells can peek under the blindfold, increasing their mutation rate in response to stress. ... read more

Flu Remedies Help Combat E. Coli Bacteria

Aug. 25, 2015 — If the intestinal bacteria level becomes unbalanced, it can cause diseases. Physiologists now reveal how a specific carbohydrate in the intestinal mucosa heavily multiplies certain E. coli bacteria ... read more

Lemon Juice Disinfects Against Human Norovirus

Aug. 25, 2015 — Citric acid may prevent the highly contagious norovirus from infecting humans, scientists discovered. Therefore, lemon juice could be a potentially safe and practical disinfectant against the most ... read more

Aug. 25, 2015 — Researchers combined the power of two computational programs to determine the atomic structure of the abiological molecule cyanostar. This breakthrough will allow researchers to investigate the ... read more

Aug. 25, 2015 — Scientists have described precisely how a plant can sense a pathogen, bringing an unprecedented level of detail to a fundamental hypothesis in plant immunity of relevance to tackling disease in ... read more

Aug. 25, 2015 — When our cells copy their DNA to grow and replicate, it’s vital the process runs smoothly. To get this right, cells use a complex “machine”, made from many hundreds of ... read more
