Applications in Plant SciencesNew formula invented for microscope viewing, substitutes for federally controlled drug In the May issue of Applications in Plant Sciences, researchers introduce Visikol, a proprietary new formulation that effectively clears organisms for viewing under microscopes. Visikol can replace chloral hydrate, which was previously one of the few high-quality clearing solutions but which is regulated by the DEA due to its use as a narcotic. The study tests Visikol's utility compared to chloral hydrate and demonstrates it as an effective replacement with a higher refractive index.

PLOS ONENow we know why old scizophrenia medicine works on antibiotics-resistant bacteria An old medicine for schizophrenia is effective at treating something completely different than it was designed for: antibiotic-resistant bacteria. So far it has been a mystery how this old schizophrenia medicine works, but now researchers from the University of Southern Denmark have figured it out. This can lead to a new medicine against the increasingly threatening antibiotic-resistant bacteria. Contact: Birgitte Svennevig

NatureNew X-ray method shows how frog embryos could help thwart disease An international team of scientists using a new X-ray method recorded the internal structure and cell movement inside a living frog embryo in greater detail than ever before. This result showcases a new method to advance biological research and the search for new treatments for genetic diseases.

Biological PsychiatryGenetic risk for schizophrenia is connected to reduced IQ The relationship between the heritable risk for schizophrenia and low intelligence has not been clear. Schizophrenia is commonly associated with cognitive impairments that may cause functional disability. There are clues that reduced IQ may be linked to the risk for developing schizophrenia. For example, reduced cognitive ability may precede the onset of schizophrenia symptoms. Also, these deficits may be present in healthy relatives of people diagnosed with schizophrenia.

NatureNature: X-ray tomography on a living frog embryo X-ray radiographs provide information about internal structures of organisms such as bones. Alternatively, X-rays can image soft tissues throughout early development of vertebrates. A new X-ray method was presented recently in a Nature article published by a German-American-Russian research team. Time-lapse sequences of cellular resolution were obtained of three dimensional reconstructions showing developing embryos of the clawed frog. Instead of absorption of X-rays, the method is based on their diffraction. Contact: Monika Landgraf

European Journal of Human GeneticsEuropean Society of Human Genetics urges caution over use of new genetic sequencing techniques The use of genome-wide analysis, where the entirety of an individual's DNA is examined to look for the genomic mutations or variants which can cause health problems is a massively useful technology for diagnosing disease. However, it can also pose major ethical problems if used incorrectly, say new recommendations from the European Society of Human Genetics published on line today (16 May 2013) in the European Journal of Human Genetics.

Cell Host & MicrobeHerpes infections: Natural killer cells activate hematopoiesis Infections can trigger hematopoiesis at sites outside the bone marrow -- in the liver, the spleen or the skin. Researchers of Ludwig-Maximilians-Universitaet in Munich now show that a specific type of immune cell facilitates such "extra medullary" formation of blood cells. Contact: Luise Dirscherl

(University of Minnesota), George J. Annas, J.D., M.P.H. (Boston University), and Sherman Elias, M.D. (Northwestern University) push back against recent ACMG recommendations, and offer compelling reasons why patient autonomy must remain firmly in place as science advances.

NeuronFishing for memories In our interaction with our environment we constantly refer to past experiences stored as memories to guide behavioral decisions. But how memories are formed, stored and then retrieved to assist decision-making remains a mystery. By observing whole-brain activity in live zebrafish, researchers from the RIKEN Brain Science Institute have visualized for the first time how information stored as long-term memory in the cerebral cortex is processed to guide behavioral choices.

ScienceAsian lady beetles use biological weapons against their European relatives Once introduced for biological pest control, Asian lady beetle populations have been increasing uncontrollably. Scientists from Giessen University and the Max Planck Institute for Chemical Ecology, Jena, Germany, have now found the reason for the animal's success. Its body fluid contains microsporidia, fungus-like protozoa that parasitize body cells and can cause immense harm to their host. The Asian lady beetle is obviously resistant to these parasites. However, transferred to native species, microsporidia can be lethal.
