Despite creative efforts to tackle it, belief in conspiracy theories, alternative facts and fake news show no sign of abating. This is clearly a huge problem, as seen when it comes to climate change, vaccines and expertise in general – with anti-scientific attitudes increasingly influencing politics. So why can’t we stop such views from spreading? […]
Alternative explanation for landslides in Mars Long landslides on Mars may have been caused by vibrations of unstable light rocks at the bottom of the slide. The findings, which offer an alternative view to previous suggestions that the landslides were caused by underlying ice, could give researchers more insight on the landslide risks on Mars […]
We usually take for granted that aromaticity is something that belongs to the ground state of a molecule; but the fact is that nothing forbids aromaticity appearing in an excited state. In the same way that molecular properties are largely affected by the ground-state aromaticity, excited-state aromaticity can guide the understanding of excited-state processes, the […]
Wouldn´t it be great to have a drug that could kill specifically our old damaged cells allowing us to have a better health at an advanced age? But we are not talking about a dreamed magic immortality pill. Senolytic drugs, compounds that kill senescent cells, are already a reality and represent a new concept that […]
No matter how elegant your theory is, experimental data will have the last word. Observations of the retrograde motion of the planets were fundamental to the Copernican revolution, in which the sun replaced Earth at the centre of the solar system. And the unusual orbit of Mercury provided a spectacular confirmation of the theory of […]
Satellite data, algorithms can help predict volcanic eruptions Satellite radar and algorithms can be used to determine when a volcano is on the verge of an eruption. Interferometric synthetic aperture radar images can show ground movement at volcanoes and an algorithm can analyze the changes, compare them to previous movements and create an alert. Eos […]
One of the unique features of the chemistry of carbon (and, to some extent, silicon) is its ability to form long chains of atoms. Polymers are substances that have macromolecules composed of many repeating units (known as ‘mers’). Many naturally occurring substances are polymers, including rubber and many substances based on glucose, such as the […]
“The b rain is considered an isolated tissue from the rest of the body thanks to the blood-brain-barrier, which separates it at cellular level with a very strict control”. That was supposed in the past, at least until now… In 2019 a striking discovery led by the researcher Moreno-Jimenez demonstrated human neurogenesis is abundant and […]
I know it seems like an absurd question to start with: can a foetus without egg and sperm even exist? As scientists show in a recently published article in the journal Cell , at least for mouse embryos in the lab, it is not only possible, it is a reality. These researchers used EPS, short […]
New image offers closer view of interstellar object Astronomers used the W.M. Keck Observatory’s Low-Resolution Imaging Spectrometer to take a new image of 2I/Borisov, the second interstellar object ever observed passing through our solar system. The image shows the coma of the interstellar comet, which will pass by the sun early next month and Earth […]
