Astronomy & Space news

	Giant cosmic tsunami wakes up comatose galaxies Galaxies are often found in clusters, with many 'red and dead' neighbours that stopped forming stars in the distant past. Now an international team of astronomers, led by Andra Stroe of Leiden Observatory and David Sobral of Leiden and the University of Lisbon, have discovered that these comatose galaxies can sometimes come back to life. If clusters of galaxies merge, a huge shock wave can drive the birth of a new generation of stars – the sleeping galaxies get a new lease of life. The scientists publish their work in the journal Monthly Notices of the Royal Astronomical Society.
	The riddle of galactic thin–thick disk solved A long-standing puzzle regarding the nature of disk galaxies has finally been solved by a team of astronomers led by Ivan Minchev from the Leibniz Institute for Astrophysics Potsdam (AIP), using state-of-the-art theoretical models. The new study shows that groups of stars with the same age always flare as the result of massive galactic collisions. When taken all together, these flares, nested like the petals of a blooming rose, puff up the disk and constitute what astronomers call the "thick" disk.

	Practical applications of 'nudge' psychology Following the publication of Richard Thaler and Cass Sunstein's persuasive book "Nudge", nudges have become a popular tool in many fields from tax collection to public health and not least among advertisers, but a thorough review of existing research suggests that the evidence that the concept is based on flimsy evidence at best.
	Hope for an effective malaria therapy with just one tablet Approximately 584,000 people worldwide die of malaria each year. The epidemic strongly associated with poverty claims most of its victims in Africa, where it particularly affects the weakest, children and pregnant women. Current therapies have to be taken over several days to be effective against malaria. "Due to supply bottlenecks, but also the quick reduction of symptoms, the administration of therapies over several days is often inadequate which can lead to treatment failure and ultimately represent a threat to the patients", so Michael Ramharter of the Infectiology and Tropical Medicine Division of the University for Internal Medicine I at MedUni Vienna on the occasion of the World Malaria Day. First results of a multicentre study with Ramharter as "Principal Investigator" now provide hope for the malaria therapy with just one dose.

	Systematic interaction network filtering in biobanks While seeking targets to attack Huntington's disease, an incurable inherited neurodegenerative disorder, neurobiologists of the research group led by Professor Erich Wanker of the Max Delbrück Center for Molecular Medicine in the Helmholtz Association found what they were looking for. Using a filtering strategy borrowed from criminologists, the researchers systematically filtered interaction networks of various biological databases. In several steps, they increasingly narrowed down their search until they ultimately found the protein (CRMP1). In subsequent lab experiments the researchers showed that CRMP1 acts like a "chaperone", ensuring that the protein huntingtin (HTT) behaves correctly and does not misfold or clump. Dysregulated modulation of the HTT protein by the CRMP1 protein is regarded as a causal mechanism of Huntington's disease.
Orphaned boys as vulnerable to abuse as girls Orphaned children in low- and middle-income countries face a high risk of trauma, with physical and sexual abuse being by far the most prevalent traumatic events.

Biology news

	Biodiversity promotes multitasking in ecosystems A new study of the complex interplay between organisms and their environment shows that biodiversity—the variety of organisms living on Earth—is even more important to the healthy functioning of ecosystems than previously thought.
	Beyond genes: Are centrioles carriers of biological information? Centrioles are barrel-shaped structures inside cells, made up of multiple proteins. They are currently the focus of much research, since mutations in the proteins that make them up can cause a broad range of diseases, including developmental abnormalities, respiratory conditions, male sterility and cancer. Publishing in Cell Research, EPFL scientists show that the original centrioles of a fertilized egg, which only come from the father, persist across tens of cell divisions in the developing embryo. The surprising finding raises the possibility that centrioles may actually be carriers of information, with profound implications for biology and disease treatment.
	How RNA machinery navigates our genomic obstacle course Once upon a time, scientists thought RNA polymerase—the molecule that kicks off protein synthesis by transcribing DNA into RNA—worked like a wind-up toy: Set it down at a start site in our DNA and it would whir steadily along, reeling off an RNA copy, until it reached the stop site.
	How to kill a protein For decades scientists have been looking closely at how our cells make proteins. But the inverse is equally important: how cells kill them.
	Bumblebee genomes give insights into threats to pollinators The first full genome sequences of two bumblebee species are published this week in the open access journal Genome Biology. They give insights into the genetic basis and evolution of important aspects of bumblebee biology from social living to coping with chemicals and diseases. These insights provide valuable hints about threats to bees' wellbeing and could help prevent further population declines of these key pollinators.

	The appeal of being anti-GMO A team of Belgian philosophers and plant biotechnologists have turned to cognitive science to explain why opposition to genetically modified organisms (GMOs) has become so widespread, despite positive contributions GM crops have made to sustainable agriculture. In a paper published April 10 in Trends in Plant Science, they argue that the human mind is highly susceptible to the negative and often emotional representations put out by certain environmental groups and other opponents of GMOs. The researchers urge the general public to form opinions on GMOs on a case-by-case basis, thereby not focusing on the technology but on the resulting product.
