Two of the great observatories, the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope, have captured views of a unique experiment to smash a spacecraft into a small asteroid. NASA’s Double Asteroid Redirection Test (DART) impact observations mark the first time that Webb and Hubble were usedContinuar Leyendo
Adaptive imaging technique for materials science and structural biology. Vienna, September 29, 2022.- A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for adaptive electron microscopy, maximizing sensitivity while minimizing beam-induced damage.Continuar Leyendo
El 26 de septiembre, la NASA hizo colisionar deliberadamente su nave espacial DART (Double Asteroid Redirection Test por sus siglas en inglés) contra el asteroide Dimorphos de 160 metros de ancho, en la primera prueba de desviación jamás realizada mediante un «impacto cinético». En el momento en que la naveContinuar Leyendo
ESA’s Hera mission team congratulates their counterparts in NASA’s DART mission team for their historic impact with the Dimorphos asteroid. Moving at 6.1 km per second, the vending-machine-sized Double Asteroid Redirect Test spacecraft struck the 160-m diameter asteroid at 01:15 CEST (00:15 BST) in the early hours of Tuesday morning,Continuar Leyendo
An international collaboration led by researchers from the University of Bern and the University of Queensland in Australia has demonstrated that chemical compounds containing special metals are highly effective in fighting dangerous fungal infections. These results could be used to develop innovative drugs which are effective against resistant bacteria andContinuar Leyendo
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have spotted signs of a ‘hot spot’ orbiting Sagittarius A*, the black hole at the centre of our galaxy. The finding helps us better understand the enigmatic and dynamic environment of our supermassive black hole. París, Sept 22“We think we’re looking atContinuar Leyendo
The NASA/ESA/CSA James Webb Space Telescope is showing off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this peculiar planet’s rings in more than 30 years, but its cameras are also revealing the ice giant in a wholeContinuar Leyendo
A mutation in the small protein SHMOOSE is associated with Alzheimer’s risk and highlights a possible target for treatment Los Angeles, Sept 21, 2022.- A mutation in a newly discovered small protein is connected to a significant increase in the risk for Alzheimer’s disease, expanding the known gene targets forContinuar Leyendo
Un cohete Soyuz despegó este 21 de septiembre rumbo a la Estación Espacial Internacional (ISS) desde Baikonur, en Kazajistán, con dos rusos y un estadounidense a bordo, en medio de tensiones por invasión de Ucrania. Baikonur, 21 de Septiembre de 2022.- «La estabilidad es buena (…), la tripulación se siente bien»,Continuar Leyendo
Highly conserved genes ensure lifelong differentiation of neurons and glandular cells in sea anemones Vienna, Sept 20, 2022.- The genetic fingerprint of the sea anemone Nematostella vectensis shows that the members of this evolutionarily very old animal phylum use the same gene cascades for the differentiation of neuronal cell typesContinuar Leyendo
