Antidepressants are the mainstay for treating depression, but their use is clouded by doubts about their short-, medium- and long-term efficacy. This is not to say that we should not use them, as these drugs save lives in many cases, but a recent review reinforces these questions as it sees little difference in the quality […]
Most internet users are by now aware of the vulnerability of their personal data. When the news broke that tech companies misuse and manipulate our personal data, there was a widespread “techlash” against the corporate giants Facebook, Amazon and Google. The explicit motive for data harvesting is the prediction of consumer wants and needs. And […]
The scattering of conduction electrons in metals due to impurities with magnetic moments is known as the Kondo effect, after Jun Kondo, who analysed the phenomenon in 1964. This scattering increases the electrical resistance and has as a consequence that, in contrast to ordinary metals, the resistance reaches a minimum as the temperature is lowered […]
The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the material is heated on a microscopic hot […]
A single MRI scan of the brain using standard equipment could be enough to diagnose Alzheimer’s disease, according to new results. The research uses machine learning technology to look at structural features within the brain, including in regions not previously associated with Alzheimer’s. The advantage of the technique is its simplicity and the fact that […]
Nay, nay, I say! This cannot be, That machines should e’er surpass our art. We are the masters, them the slaves, And thus it ever shall be so! They learn, ‘tis true, but they learn Only what we bid them learn, no more. They cannot understand the heart Or beauty of our words, you see […]
Multiple sclerosis (MS) is a debilitating autoimmune condition whereby neurons lose their myelin sheath leading to impaired neural transmission, neural degeneration and motor symptoms. Multiple factors have been considered to influence its development, like vitamin D, but now, a couple of studies have shown that the Epstein-Barr virus (EBV) is linked to multiple sclerosis. You […]
Machine-learning systems are increasingly worming their way through our everyday lives, challenging our moral and social values and the rules that govern them. These days, virtual assistants threaten the privacy of the home; news recommenders shape the way we understand the world; risk-prediction systems tip social workers on which children to protect from abuse; while […]
Transition metal dichalcogenides (TMDs) are layered compounds which can be thinned down to the single-layer limit. While mechanical exfoliation generates atomically thin TMD flakes possessing an area of a few square microns, chemical and physical methods provide high-quality monolayers on large-area substrates, which are suitable for actual technological applications. TMDs are a class of van […]
In 2021, an investment firm bought 2,000 acres of real estate for about USD 4 million. Normally this would not make headlines, but in this case the land was virtual. It existed only in a metaverse platform called The Sandbox. By buying 792 non-fungible tokens on the Ethereum blockchain, the firm then owned the equivalent […]
