Chemistry Nobel 2018: A sad reminder...
Techniques that put natural evolution on fast-forward to build new proteins in the lab have earned three scientists this year’s Nobel Prize in chemistry. Frances Arnold of Caltech won for her method of creating customized enzymes for biofuels, environmentally friendly detergents and other products. She becomes the fifth woman to win the Nobel Prize in…

Mapping the brain. But not your brain…
To map neurons, researchers currently use an electron microscope to take pictures -- with one image usually containing a small number of neurons. The researchers then study each neuron's shape and size as well as its thousands of connections with other nearby neurons to learn about its role in behavior or biology. "We don't know…

Testability. The criterion for good theories. The death of modern humans.
Scientists are testing a theory of particles in a Weyl semimetal instead of testing it near a black hole. Because the behavior or particles in a semimetal is similar to the behavior of particles near a black hole. At the same time string theory has been maligned because it makes predictions that cannot be tested.…

Chirality. Pasteur. Art, intuition and science…
Louis Pasteur, the 19th-century French chemist and biologist, prevented diseases, developing a process — widely known as pasteurization — for killing microbes in milk and wine. He also created vaccines for rabies and anthrax. And his ideas led to the acceptance of germ theory, the notion that tiny organisms caused diseases like cholera. Pasteur even…

Science modelling: Can scientific models ever be “wrong”? A not-so-evident answer…
Can scientific models be falsifiable? Let’s read two stories of changes in scientific models and try to find out the answer. If you are bored to read, skip directly to the Conclusion at the end… You will get the meaning. Story 1: Modelling sun spots… A group of researchers believes that contrary to a common…
