From childhood, we are taught that the world exists in three physical dimensions. That’s true, for the most part, but it skips over something quite fascinating: the strange two-dimensional world of nanoscale materials, like the ‘wonder material’ graphene. Graphene and its engineered, single-layer counterparts do in fact exist in three dimensions, albeit just barely –

A new technique involving entangled photons has just led to a world first. Physicists have overcome a significant limitation of traditional holography by using quantum mechanics to successfully encode information within a hologram. This could result in a significant upgrade to holography, from entertainment purposes to more serious applications such as medical imaging. “Classical holography

In a survey of 172 Italian CEOs, those who scored higher in extraversion, overconfidence, self-esteem, dominance,

Changes in Mars‘ geography always attract significant scientific and even public attention.  A hope for signs of liquid water (and therefore life) is likely one of the primary driving forces behind this interest.  One particularly striking changing feature is the Recurring Slope Lineae (RSL) originally found by the Mars Reconnaissance Orbiter (MRO). Now, scientists at the SETI Institute have a

An investigation in Poland has found people who show certain antisocial personality traits are more likely to support radical group actions and violence. Among 877 students, psychologists found those who ranked highly for ‘disinhibition’ or ‘meanness’ also displayed greater political radicalisation in a survey.  Meanness, which refers to cold-heartedness or callousness, was found to be

US cities are significantly undercounting their greenhouse gas emissions, according to a new study published this week in Nature Communications. The researchers compared self-reported emissions data from 48 US cities to independent estimates based on federal data about factories, power plants, and roads, among other sources. They found cities are under-reporting by nearly 20 percent.

The discovery of a rare “mud mummy” from ancient Egypt has surprised archaeologists, who weren’t expecting to find the deceased encased in a hardened mud shell. The “mud carapace” is an unparalleled find; it reveals “a mortuary treatment not previously documented in the Egyptian archaeological record,” the researchers wrote in the study, published online Wednesday (Feb. 3)
