E. coli variant created with synthetic genome An artificial version of Escherichia coli was created with a synthetic genome. Researchers built the genome piece by piece because “the bacterial chromosome is so big, we needed an approach that would let us see what had gone wrong if there had been any mistakes along the way,” […]
So-called “valleytronics” is a new type of electronics that could lead to faster and more efficient computer logic systems and data storage chips in next-generation devices. Valley electrons are so named because they carry a valley degree of freedom, a pseudospin. This is a new way to harness electrons for information processing that’s in addition […]
Technology by itself is not good or bad but it can be given good or bad uses and everything depends on the decisions made by the people who use it. One of the good uses of social networks is what some scientists are doing to create academic networks outside of their work, as well as […]
One of the most important ethical debates of the next decades will be, no doubt, the one about our moral obligations towards non-human beings, and in particular, towards the members of other animal species. Very likely, not only philosophical discussions, but even the attitudes of a big portion of citizens about this topic, are going […]
Oxygen shifts linked to animal evolution during Cambrian explosion The rise and fall of atmospheric oxygen levels during the Cambrian explosion have been linked to the evolutionary changes in animal biodiversity at the time. Researchers looked at changes in organic carbon and sulfur during that period to get an idea of the oxygen fluctuations in […]
Back in 1929, theoretical physicist Hermann Weyl predicted the existence of a new elementary particle with intriguing properties. Specifically, it would be massless (like a photon), have half-integer spin (like an electron) and exist in two mirror-image versions (like left- and right-handed gloves)—a property known as chirality. Imagine there exist a material in which an […]
Zoë Firth & Priscila Borba Borges, students, European Master’s in Clinical Linguistics (EMCL+) and Adrià Rofes (advisor) ‘ I can’t control my brain’. So sang Weezer in their 2001 hit ‘Island in the Sun’; how fitting, then, that this was the song teenager Kira Iaconetti chose to sing during her brain surgery. That’s right: during […]
In the previous chapter of this series, we went over the subjective, relative separation of the network of events known as Spacetime into space and time. The speed of light played a major role in the discussion. In particular, we divided Spacetime into three regions (with respect to a particular event) defined by the existence […]
Bright gamma-ray flashes found around pulsars Extremely bright gamma-ray flashes known as Cherenkov emissions have been detected circling around pulsars, created when charged particles moving in a sense faster than light travel through the pulsar’s surrounding quantum vacuum. “This is a very exciting new prediction because it could provide answers to basic questions such as […]
With the possible exception of Avogadro’s number, which was in reality defined and made popular by Stanislao Cannizzaro, many things in the sciences are usually named after the person who makes them popular. The Seebeck effect is an example. Originally discovered in 1794 by Alessandro Volta, it is named after Thomas Johann Seebeck, who in […]
