Meteorites may have brought water to Earth Analysis of fragments of a meteorite that landed in the driveway of a British home in 2021 revels the space debris originated in the outer solar system and held water chemically similar to the water found on Earth. The meteorite came from an asteroid in Jupiter’s orbit some […]

When we consider the concepts metal and catalysis, we tend to assume quite matter-of-factly that the metal will be the catalyst. This assumption is based on the fact that metals can be found in reactions where they act as catalysts or co-catalysts in the form of coordination and organometallic compounds, nano-sized or bulk materials and […]
Bringing together concepts from electrical engineering and bioengineering tools, scientists have produced genetic “devices” designed to perform neuromorphic computations like artificial neural circuits in bacterial cells. The genetic material was inserted into bacterial cells in the form of a plasmid: a relatively short DNA molecule that remains separate from the bacteria’s “natural” genome. Plasmids also […]
For the first time, a Nobel Prize recognized the field of anthropology, the study of humanity. Svante Pääbo, a pioneer in the study of ancient DNA, or aDNA, was awarded the 2022 prize in physiology or medicine for his breathtaking achievements sequencing DNA extracted from ancient skeletal remains and reconstructing early humans’ genomes – that […]
Layered rocks may be Earth’s oldest known fossils Researchers have found fossil evidence of what may be the first known life on Earth with the discovery of stromatolites, layered rocks formed by photosynthetic microbes, in Western Australia’s Dresser Formation that date back 3.48 billion years. Full Story: Live Science Sharks face rising extinction risk, other […]
In the last decades, a new synthetic approach has been developed, generally termed as “on-surface synthesis” that substantially departs from standard chemistry in solution. Instead of the three-dimensional space of solvents in the latter, the environment of the reactants in this new approach are well-defined two-dimensional solid surfaces that are typically held under vacuum conditions […]
Our brains “time-stamp” the order of incoming sounds, allowing us to correctly process the words that we hear, shows a new study by a team of psychology and linguistics researchers . “To understand speech, your brain needs to accurately interpret both the speech sounds’ identity and the order that they were uttered to correctly recognize […]
According to theory of degrowth , the only way to save the planet and humanity from catastrophic collapse due to depletion of natural resources would be to radically limit, and even reduce, global production levels and, since there is still a large part of the population living in intolerable levels of poverty, and the only […]
Gene editing to combat the negative effect of climate change in plants Plant biology experts agree that gene editing is a tool that has great potential for use in combating the negative effect of climate change in plants and that the technology “will be a relevant approach as soon as the genetic determinants of this […]
Cyclic polymers present a topology that differ significantly from their linear counterparts due to their circular structure and, therefore, the lack of chain ends. These simple characteristics are responsible for important unique properties (e.g. lower intrinsic and melt viscosity, lower hydrodynamic volumes, slower degradation profiles, increased blood circulation times and more selective bioaccumulation) thanks to […]
