Replicability of results. A problem we choose to ignore.
Can companies rely on the results of one or two scientific studies to design a new industrial process or launch a new product? In at least one area of materials chemistry, the answer may be yes - but only 80 percent of the time. The replicability of results from scientific studies has become a major…

Implanting information directly in the brain… So?
Two neuroscientists at the University of Rochester say they have managed to introduce information directly into the premotor cortex of monkeys. The researchers published the results of the experiment in the journal Neuron. Although the research is preliminary, carried out in just two monkeys, the researchers speculated that further research might lead to brain implants…

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…

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…
