High levels of a hormone found in cells in the gut could underlie many cases of chronic diarrhoea and help explain up to 40% of cases of patients with irritable bowel syndrome with diarrhoea, according to a new study led by scientists at the University of Cambridge. Cambrigde, Aug 01,Continuar Leyendo
Researchers control ring polymer shapes by tuning electric charge What if a complex material could reshape itself in response to a simple chemical signal? A team of physicists from the University of Vienna and the University of Edinburgh has shown that even small changes in pH value and thus inContinuar Leyendo
More than one star contributes to the irregular shape of NGC 6072 París, July 30, 2025.- Webb’s newest look at planetary nebula NGC 6072 in the near- and mid-infrared shows what may appear as a very messy scene resembling splattered paint. However, the unusual, asymmetrical scene hints at more complicatedContinuar Leyendo
Autophagy is essentially the ‘rubbish collection’ of our cells. If there are problems in this process, which is so important for our health, diseases such as Parkinson’s can result. In their latest study, leading cell biologists at the Max Perutz Labs at the University of Vienna investigated mitophagy – aContinuar Leyendo
Scientists have discovered that certain species of microbe found in the human gut can absorb PFAS – the toxic and long-lasting ‘forever chemicals.’ They say boosting these species in our gut microbiome could help protect us from the harmful effects of PFAS. Cambrigde, July 13, 2025.- PFAS have been linked withContinuar Leyendo
To mark its third year of highly productive science, astronomers used the NASA/ESA/CSA James Webb Space Telescope to scratch beyond the surface of the Cat’s Paw Nebula (NGC 6334), a massive, local star-forming region. Paris, July 10, 2025.- Webb’s NIRCam instrument was used to look at this particular area ofContinuar Leyendo
New York, July 09, 2025.- The COVID pandemic illustrated how urgently we need antiviral medications capable of treating coronavirus infections. To aid this effort, researchers quickly homed in on part of SARS-Cov-2’s molecular structure known as the NiRAN domain—an enzyme region essential to viral replication that’s common to many coronaviruses.Continuar Leyendo
An international collaboration featuring the University of Vienna and the University of Wisconsin-Madison (USA) has led to the first-ever chromosome-level genome assembly of a sea spider (Pycnogonum litorale). The genome informs about the development of the characteristic sea spider body plan and constitutes a landmark for revealing the evolutionary historyContinuar Leyendo
Ythaca, NY, July 06, 2025.- Nutrition scientists have been working to understand the relationship between Type 2 diabetes and genes that express a salivary enzyme that breaks down starch, but many conflicting studies have led to few clear answers. Now, a new study published July 2 in PLOS One bringsContinuar Leyendo
Endoscopies could be replaced by far less invasive capsule sponge tests for half of all patients with Barrett’s oesophagus, a known precursor to oesophageal cancer, according to a new study. The capsule sponge test is easier to administer and could be carried out by nurses and at GP practices, reducingContinuar Leyendo
