Nature is a source of inspiration for scientists. If the efficiency of natural processes efficiency has been honed by billions of years of evolution, it seems reasonable that the best way to achieve some process is to try and mimic what nature has already come up with. This is the case with photosynthesis, a process […]
It is generally considered that equality of opportunities means equal access to education and health. When the society considers that some goods like school and vaccines must be consumed by everyone, economists define them as “merit goods”, which deserve a special treatment, as in the case of public goods or goods that cause consumption externalities […]

Mode of delivery may affect breast milk’s bacterial composition Canadian researchers found that pumped breast milk had reduced levels of healthy bifidobacteria and elevated levels of some infection-causing bacteria, such as Pseudomonadaceae and Stenotrophomonas, compared with directly breastfed milk. Health Day Honeybees’ brains tracked while navigating VR maze Researchers got a glimpse into honeybee brains […]
Light waves spread and bend as they pass through an aperture or round the edge of a barrier. This is a well-known phenomenon called diffraction. Diffraction imposes a limit to the size of objects that we can observe sharply using light of a given wavelength, for a given microscope will have a minimum aperture, and […]

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 […]
