A number of technologies and tools got a chance to prove themselves for the first time in the context of COVID-19. Three researchers working in gene-based vaccines, wearable diagnostics and drug discovery explain how their work rose to the challenge of the pandemic, and their hopes that each technology is now poised to continue making […]
Inherited or somatic mutations targeting genes which encode essential cell growth regulatory proteins favor the emergence of cancer. Cells carrying these mutations acquire growing and survival advantages that trigger the emergence of the tumor. A large number of tumor-associated mutations, as well as many mutations found in the germline of hereditary cancer patients, are single-nucleotide […]
Massive space storm over the North Pole A huge storm in space rained electrons on Earth’s atmosphere above the North Pole in an event scientists are calling a space hurricane. A global team of researchers spotted the space storm while reviewing satellite data from the last six years. NBC Nearby exoplanet may help scientists study […]
Molecules when excited from their ground state (S 0 ) to their lowest electronically excited states often change their electronic structure considerably, which impacts on a range of important molecular properties. For example, the reactivity of a molecule in its excited state often differs markedly from that in its S 0 state. Also, the charge […]
Nearly a century after dark matter was first proposed to explain the motion of galaxy clusters, physicists still have no idea what it’s made of. Researchers around the world have built dozens of detectors in hopes of discovering dark matter. As a graduate student, I helped design and operate one of these detectors, aptly named […]
Let me make a short interruption in our series about the prehistory of philosophy of science, to discuss a completely different point. I am writing this now, just because in the last days I think I have been able to clearly formulate a specific perplexity that for many years I had felt about what we […]
Nightside of Venus seen in new Parker Solar Probe image NASA has shared a rare image of the nightside of Venus taken by the Parker Solar Probe as it swung by the planet for a gravity boost on its way to study the sun. The image, which shows a glow around Venus, was taken by […]
A cement is any of various substances used for bonding or setting to a hard material. A popular one, Portland cement, is a mixture of calcium silicates and aluminates made by heating limestone (CaCO3) with clay (that contains aluminosilicates) in a kiln. The product is then ground to a fine powder. When Portland cement is […]
Gliomas are the most prevalent subtype of primary brain tumours originating from mutations of the glia cells in the central nervous system. Gliomas are characterized by fast cell growth, strong invasion capability, and well-developed tumour vasculature. Although research and clinical trials have allowed significant progress in the comprehension and treatment of gliomas, they still have […]
The close interconnection between the gut and the central nervous system is already well described, what is new is the possibility of some of the brain’s defense systems originating in the gut. New research in mice published in the journal Nature found that immune cells are first trained in the gut and then migrate to […]
