Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious. Cambrigde, April 21, 2025.- Using data from the James Webb Space Telescope (JWST), the astronomers, led by the University of Cambridge, have detected the chemical fingerprints of dimethyl sulfide (DMS)Continuar Leyendo
In anticipation of the upcoming 35th anniversary of the NASA/ESA Hubble Space Telescope, ESA/Hubble is continuing the celebrations with a new view of the Eagle Nebula. This vast stellar nursery displays a towering spire of cosmic gas and dust that incorporates new data processing techniques developed since an image ofContinuar Leyendo
Scientists from the Institut Pasteur, in collaboration with Kumamoto University in Japan, have assessed a new rapid diagnostic test to identify pregnant women at elevated risk of transmitting hepatitis B to their babies. This diagnostic tool could help eliminate hepatitis B by preventing mother-to-child transmission during childbirth, especially in low-Continuar Leyendo
New York, April 17, 2025.- “Nature vs. nurture” is not just a human debate: Every organism with DNA is influenced by its environment. With that in mind, a new project led by Cornell researchers will explore how genetically identical grapevines adapt to differences in temperature, humidity, soils and other environmentalContinuar Leyendo
Magnetars are ultra-dense stellar remnants with extremely strong magnetic fields. Researchers using the NASA/ESA Hubble Space Telescope have discovered that the magnetar SGR 0501+4516 was not born in a neighbouring supernova as previously thought. The birthplace of this object is now unknown, and SGR 0501+4516 is the likeliest candidate inContinuar Leyendo
The University of Bern is represented in the Swiss Pavilion at Expo 2025 in Osaka, which officially opened yesterday. As part of the “AUGMENTED HUMAN” exhibition, two Bernese space instruments that are flying on international missions into space can be seen in the Swiss Pavilion. And the public has theContinuar Leyendo
Ithaca, April 08, 2025.- Knocking out a single gene reprograms part of the large intestine to function like the nutrient-absorbing small intestine. In a preclinical study, Weill Cornell Medicine investigators showed that the technique reversed the malnutrition that results when most of the small intestine is removed. The successful demonstrationContinuar Leyendo
Body signals such as heartbeat and breathing accompany us constantly, often unnoticed as background noise of our perception. Even in the earliest years of life, these signals are important as they contribute to the development of self-awareness and identity. However, until know little has been known about whether and howContinuar Leyendo
An international team of astronomers using the NASA/ESA Hubble Space Telescope have made new measurements of Uranus’ interior rotation rate with a novel technique, achieving a level of accuracy 1000 times greater than previous estimates. By analysing more than a decade of Hubble observations of Uranus’ aurorae, researchers have refinedContinuar Leyendo
Researchers at the Inselspital, Bern University Hospital and the University of Bern have developed an AI-based tool that detects and classifies abnormalities of the coronary arteries in CT images with high precision. This could significantly improve the diagnosis and treatment of rare heart diseases. The study demonstrates the concrete applicationsContinuar Leyendo
