How Newts Can Help Osteoarthritis Patients

Aug. 20, 2015 — Osteoarthritis is the most common form of joint disease worldwide. Now, scientists have taken a leaf out of nature’s book in an attempt to develop effective stem cell treatment for osteoarthritis, ... read more

Aug. 20, 2015 — When they think about how cells put together the molecules that make life work, biologists have tended to think of assembly lines: Add A to B, tack on C, and so on. But the reality might be more like ... read more

Aug. 19, 2015 — New research could one day help build computers from DNA. Scientists have found a way to 'switch' the structure of DNA using copper salts and EDTA (Ethylenediaminetetraacetic acid) -- an ... read more

Aug. 19, 2015 — The expected impact of climate change on North American lizards is much worse than first thought. A team of biologists has discovered that lizard embryos die when subjected to a temperature of 110 ... read more

Aug. 18, 2015 — Each cell in a woman's body contains two X chromosomes. One of these chromosomes is switched off, because nobody can live with two active X chromosomes. Researchers have now shown the mechanism ... read more

Aug. 17, 2015 — For some, TOR may bring to mind a Celtic mountain or perhaps an Internet privacy group. In the world of molecular biology it's a cellular pathway that's found in everything from yeast to ... read more

Aug. 17, 2015 — A scientific peek into bacteria boudoirs is revealing how 'sex' among disease-causing microbes can lead different species or strains to become resistant to antibiotic medications. In a ... read more

Aug. 13, 2015 — When fruit flies are attacked by parasites or bacteria they respond by producing offspring with greater genetic variability, new research shows. This extra genetic variability may give the offspring ... read more

Aug. 13, 2015 — A helpful subset of the intestinal microbiome, lactobacilli, stimulates the cytoprotective Nrf2 pathway in both flies and mice. The findings could potentially lead to advances in the use of bacteria ... read more

How Lipids Are Flipped

Aug. 12, 2015 — A team of researchers has succeeded in determining the structure of a lipid flippase at high resolution, which has provided insight into how this membrane protein transports lipids by ... read more

Aug. 12, 2015 — Imagine a skeleton-less creature with three hearts, with most of its nearly half a billion neurons distributed in eight tentacular arms. Each arm can regenerate like the mythical Hydra and has a mind ... read more

How Human Cells Can Dissolve Damaging Protein Aggregates

Aug. 11, 2015 — Cellular repair systems can dissolve aggregated proteins and now researchers have successfully decoded the fundamental mechanism that is key to dissolving these protein aggregates in human cells. ... read more

Bioengineers Identify Key Genes, Functions for Sustaining Microbial Life

Aug. 10, 2015 — A new study defines the core set of genes and functions that a bacterial cell needs to sustain life. The research, which answers the fundamental question of what minimum set of functions bacterial ... read more

Aug. 10, 2015 — In female mammals, one of the two X chromosomes is inactivated. Thanks to research using special stem cells, geneticists have been able to provide detailed insight into the molecular mechanism behind ... read more

Aug. 7, 2015 — Before new chemicals can be approved, environmental risk assessments have to be carried out. But conventional toxicity testing with live fish is costly and time-consuming, and new substances continue ... read more

Aug. 7, 2015 — When the right gene is expressed in the right manner in the right population of stem cells, the developing mouse brain can exhibit primate-like features. Researchers succeeded in mimicking the ... read more

Aug. 7, 2015 — An ichneumonid parasitic wasp seizes control of the parasitized spider and exploits its 'resting web' building behavior as seen before moulting, scientists have discovered. Researchers ... read more

Aug. 6, 2015 — To combat pathogens, the immune system has developed various mechanisms to detect, defend against and even destroy micro-organisms that are harmful to the body. This includes antimicrobial peptides ... read more

DNA Repair: Pincer Attack

Aug. 6, 2015 — Defects in DNA can cause serious harm to an organism, including cell death or the development of cancer. Efficient repair mechanisms are therefore of vital importance. Researchers have explained for ... read more

Aug. 5, 2015 — Scientists have, for the first time, found further evidence of how the differentiation of pluripotent cells is tied to and controlled by the cell cycle clock. This deeper understanding of how cells ... read more
