UrduMientras observaban una galaxia recién inactiva utilizando el Atacama Large Millimeter/submillimeter Array (ALMA) y el Telescopio Espacial Hubble (HST), un equipo científico descubrió que este había dejado de formar estrellas no porque hubiera agotado todo su gas, sino porque la mayor parte de su combustible para la formación de estrellas había sido expulsado del sistema cuando se fusionó con otra galaxia. Este resultado constituye una primicia para los astrónomos y astrónomas de ALMA. Además, si se demuestra que este resultado es común, podría cambiar la forma en que la comunidad científica entiende las fusiones y muertes de galaxias.

ALMA Witnesses Deadly Star-Slinging Tug-of-War Between Merging Galaxies
While observing a newly-dormant galaxy using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope (HST), scientists discovered that it had stopped forming stars not because it had used up all of its gas but because most of its star-forming fuel had been thrown out of the system as it merged with another galaxy. The result is a first for ALMA scientists. What’s more, if proven common, the results could change the way scientists think about galaxy mergers and deaths.

State-level Earned Income Tax Credit linked to reduction in high-risk HIV behavior among single mothers
UCLA research finds that a refundable State-level Earned Income Tax Credit (SEITC) of 10% or above the Federal EITC was associated with a 21% relative risk reduction in reported behavior that could put single mothers at high risk for becoming infected with HIV during the previous year. Also, a 10 percentage-point increase in SEITC was linked to a 38% relative reduction in the same reported high-risk behavior the previous year.

Bacteria provide immunity against giant viruses
Amoebae receive surprising support in defense against viruses: The bacteria they are infected with prevent them from being destroyed by giant viruses. A research team led by microbiologist Matthias Horn from the Centre for Microbiology and Environmental Systems Science at the University of Vienna have investigated how a virus infection proceeds when the amoebae are simultaneously infected with chlamydia. The research team shows for the first time that intracellular bacteria known as symbionts protect their host against viruses. Amoebae are protists, i.e. single-celled microorganisms with a cell nucleus. Protists play a key role in food webs and ecosystem processes. Consequently, the results of the study suggest that the interaction between symbionts and viruses influence the flow of nutrients in ecosystems. The study is now published in the journal PNAS.
