Reef fish may know it’s seeing its reflection in mirror A coral reef fish may be able to recognize itself in a mirror. After researchers injected a colored dye on the throats of bluestreak cleaner wrasses and placed them in a mirrored tank, the fish appeared to try to scrape the mark off after seeing […]
Organic chemistry uses lots and lots of names. Not only purely chemical names, but people’s names. This is so because the field is so broad that you need to name not only substances, that usually have two names, the official – from IUPAC rules – and the nickname, usually much shorter and easier to remember […]
Planes, ships, trucks and (most) cars run on different fractions of crude oil, composed of carbon chains of different length: Diesel (C 10 -C 22 ), kerosene (C 8 -C 16 ) and gasoline (C 5 -C 12 ). Despite their current supremacy, it is well known that fossil fuels will not be the energy […]
Molecular recognition is a critical process for many biological functions and consists in non-covalent binding of different molecules, such as protein-protein, antigen-antibody and many others. The host-guest molecules involved often show a shape complementarity, and one of the leading specification for molecular recognition is that the interaction must be selective, i.e. the host should strongly […]
Ginger molecules may boost growth of beneficial gut bacteria Molecules found in ginger may help beneficial gut bacteria grow. An increase in such bacteria was observed in mice fed ginger-derived nanoparticles. The Scientist Curiosity’s accelerometers help measure Mount Sharp’s density Accelerometers aboard the Mars rover Curiosity that are used to collect data about the machine […]
Experiments performed in 1909 by Geiger and Marsden, also called Rutherford gold foil experiment because Rutherford was their supervisor, led to the discovery of nuclear structure in the atom: the nucleus of the atom is its central core and contains most of its mass and the nucleus is positively charged. Further research during the next […]
Recently, the journal Science showed in its cover an amazing image of a close up into the fly brain. This is the result of the combined effort of two research groups working on imaging. The first one (Boyden’s) had developed a way to increase the size of preserved samples, like a brain slice, up to […]
The term “innovation” has been ubiquitous for decades in many areas of European society. Since Lisbon 2000—and even earlier—the European Union has promoted policies to drive innovation with the intention of restoring to Europe the economic leadership it has undoubtedly lost. Two decades later, we are close to Horizon 2020—at least chronologically speaking. Within the […]
Brain responds to rocking during sleep with improved memory A rocking motion may help people sleep better and improve their memory by influencing their brains’ sleep oscillations. “Our volunteers — even if they were all good sleepers — fell asleep more rapidly when rocked and had longer periods of deeper sleep associated with fewer arousals […]
Quantum computing is the future. Or the present, if you believe that some real quantum computers are commercially available already. Because it is hard to admit that any computer system whose design and theoretical basis depend on quantum effects for their operation may be on the market today, even though IBM says otherwise. The trick […]
