The transition to life. mRNA translation. The futility of life questions.
The transition from an egg to a developing embryo is one of life's most remarkable transformations. Yet little is known about it. Now Whitehead Institute researchers have deciphered how one aspect - control of the all-important translation of messenger RNAs (mRNAs) into proteins - switches as the egg becomes an embryo. That shift is controlled…

Fermions. Breaking the Lorenz symmetry. Shielding scientific theories from change. Breaking the tea cup.
A weird new particle imitator flouts the established rules of particle physics. The discovery could help scientists simulate how particles behaved just after the Big Bang or lead to the development of new devices with unusual electromagnetic properties. The curious new phenomenon involves a particle-like entity called a quasiparticle, formed from a jostling mosh pit…

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…

Technology works! Science works! Well, NOT QUITE... (Technology and Science do NOT work!)
Science and technology are for any the jewels in the crown of modern civilization. Their success reflects to the western culture and the nations which embrace them, their glory reflects to modern society and the modern way of thinking. We live better, we think better, we are better humans! And what better argument for that, than to show to…
