Photochemistry is common in our own Solar System and crucial to Earth’s atmospheric makeup, as well as to fundamental life processes such as photosynthesis. Washington, DC, Dec 29, 2022.- JWST has captured the first-ever evidence of a compound in the atmosphere of an exoplanet—sulfur dioxide—created by a starlight-mediated chemical reaction.Continuar Leyendo
Cambridge scientists have discovered that cancer cells ‘hijack’ a process used by healthy cells to spread around the body, completely changing current ways of thinking around cancer metastasis. Cambrigde, Dec 27, 2022.- The team based at the Cancer Research UK (CRUK) Cambridge Institute, University of Cambridge, found that blocking the activityContinuar Leyendo
The reason some people fail to recover their sense of smell after COVID-19 is linked to an ongoing immune assault on olfactory nerve cells and an associated decline in the number of those cells, a team of scientists led by Duke Health report.

París, Dec 23, 2023.- This is the antenna that will transmit back the first close-up images of the distant Dimorphos asteroid since its orbit was shifted by a collision with NASA’s DART spacecraft. The 1.13-m diameter High Gain Antenna of ESA’s Hera mission went through a week-long test campaign atContinuar Leyendo
How did the complex organisms on Earth arise? This is one of the big open questions in biology. A collaboration between the working groups of Christa Schleper at the University of Vienna and Martin Pilhofer at ETH Zurich has come a step closer to the answer. The researchers succeeded inContinuar Leyendo
Webb’s picture of the month December is dominated by NGC 7469, a luminous, face-on spiral galaxy approximately 90 000 light-years in diameter that lies roughly 220 million light-years from Earth in the constellation Pegasus. París, December 22, 2022.- This spiral galaxy has recently been studied as part of the GreatContinuar Leyendo
New York, December 21, 2022.- Life in an ant colony is a symphony of subtle interactions between insects acting in concert, more like cells in tissue than independent organisms bunking in a colony. Now, researchers have discovered a previously unknown social interaction that unites the colony, linking ants across developmentalContinuar Leyendo
Santiago, 20 de Diciembre de 2022.- La neuróloga Daniela Ávila, profesora de la Facultad de Medicina de la Pontificia Universidad Católica de Chile, está realizando una investigación que busca que en todo el país los especialistas que reciben a pacientes con miotonías no distróficas, o rigidez muscular intensa puedan aplicarContinuar Leyendo
A research group at the University of Bern is studying how plants «breathe». They have gained new insights into how grasses develop efficient «breathing pores» on their leaves. If important landmark components in this development process are missing, the gas exchange between plant and atmosphere is impaired. The findings areContinuar Leyendo
Tras la cuenta atrás en francés de diez a uno, se anuncia: «Décollage»: despegue. La colaboración de 15 años entre la NASA, la ESA y la Agencia Espacial Canadiense (CSA) acababa de entrar en su fase más crítica: el lanzamiento. Lo que sucediera posteriormente determinaría si el telescopio espacial JamesContinuar Leyendo
