Scientists have successfully demonstrated that autonomous methods can discover new materials. The artificial intelligence (AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind nanoscale “ladder.” The newly discovered structures were formed by a process called self-assembly, in which a material’s molecules organize themselves into unique patterns. Scientists at Brookhaven’s Center for […]
Clinical research has fundamentally discriminated women, assuming that they are nothing more than “small” men and therefore, drugs should work mostly the same if just adjusting the dose to their lower weight. However, this has been proven not to be the case. The physiology of the two sexes differs in several parameters, that is why […]

Last year’s Nobel Prize in Physics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in “the second quantum revolution” — a new age when we are able to manipulate the weirdness of quantum mechanics, including quantum superposition and entanglement. A large-scale and fully functional quantum network is the holy grail […]
Graphene is a key two-dimensional material that continues to reveal intriguing properties when stacked into just a few layers. But the interesting point is that it is not just a question of a layer sitting on another layer randomly, but how exactly their atoms are positioned in relation to each other. In this vein, for […]

Water has puzzled scientists for decades. For the last 30 years or so, they have theorized that when cooled down to a very low temperature like -100 ºC, water might be able to separate into two liquid phases of different densities. Like oil and water, these phases don’t mix and may help explain some of […]
Electrical stimulation of the spinal cord can help recover mobility in some paralysed patients. However, the mechanism underlying this partial recovery of function remains unknown. A recent human study has confirmed the involvement of a group of cells previously identified in mice, paving the way to targeted treatments. In a recently published study in Nature […]
Bringing together concepts from electrical engineering and bioengineering tools, scientists have produced genetic “devices” designed to perform neuromorphic computations like artificial neural circuits in bacterial cells. The genetic material was inserted into bacterial cells in the form of a plasmid: a relatively short DNA molecule that remains separate from the bacteria’s “natural” genome. Plasmids also […]
Fermentation is a form of anaerobic respiration occurring in certain microorganisms, like yeasts. Many processes arising in diverse contexts can be classified as fermentation processes, such as manufacturing of some food products (baking, wine and beer industries are based on them) and of some industrial and pharmaceutical chemicals. Alcoholic fermentation comprises a series of biochemical […]
Discarded electronic devices, such as cell phones, are a fast-growing source of waste. One way to mitigate the problem could be to use components that are made with renewable resources and that are easy to dispose of responsibly. Now, researchers have created disposable papertronics, a prototype circuit board that is made of a sheet of […]
In 1906, Alois Alzheimer, a psychiatrist and neuroanatomist, reported “a peculiar severe disease process of the cerebral cortex” to a gathering of psychiatrists in Tübingen, Germany. The case was a 50-year-old woman who suffered from memory loss, delusions, hallucinations, aggression and confusion – all of which worsened until her untimely death five years later. In […]
