Putting truth to the test in the “post-truth era”, Boston College psychologists conducted experiments that show when Americans decide whether a claim of fact should qualify as true or false, they consider the intentions of the information source.
Recent research sheds light on the mechanism behind how quantum materials change from an electrical conductor to an electric insulator. Below a critical temperature, strontium doped lanthanum strontium nickel oxide is an insulator due the separation of introduced holes from the magnetic regions, forming “stripes.” These stripes fluctuate and melt at 240K, at which temperature the material should become a conducting metal. Instead, it remains an insulator. This is because of certain atomic vibrations that trap electrons and impede electrical conduction.
In a pre-clinical, proof-of-concept study from Johns Hopkins Medicine, researchers found that epigallocatechin gallate (EGCG), a green tea compound with powerful antioxidant properties, could be promising for both treating and preventing uterine fibroids. Results of the study, first posted online May 25 in Scientific Reports, add to growing evidence that EGCG may reduce fibroid cell growth.

For decades, scientists sought a way to apply the outstanding analytical capabilities of neutrons to materials under pressures approaching those surrounding the Earth’s core. These extreme pressures can rearrange a material’s atoms, potentially resulting in interesting new properties.
A study conducted in 27 countries, led by the department of Anthropology at the University of California Los Angeles (UCLA) in which the University of Seville takes part, suggests that in the early years of the COVID-19 pandemic, traditionalism was associated with support for stricter precautionary behaviour against the epidemic.
Two new Finnish studies show that short bouts of light or moderate exercise can increase the number of immune cells in the bloodstream of cancer patients.
Fusion energy researchers use a technique called Gas-Puff Imaging (GPI) to visualize an important phenomenon in tokamak devices involving turbulence in plasma magnetic confinement fields. This technique can generate roughly 1 million frames of visual data, far too much for humans to analyze by eye. Scientists recently tested a machine-learning based approach for analyzing GPI images. The system provides detailed, time- and space-resolved information and could aid in design and operation of future fusion power devices.
Spider mites avoid chemicals extracted from caterpillar traces; the repellent effect lasts for days. Butterfly and moth caterpillars then indiscriminately consume spider mite-infested and intact leaves along with dormant individuals or their eggs.
Habitats suitable for Asian elephants (Elephas maximus) across Asia have decreased by over 64% – equating to 3.3 million square kilometres of land – since the year 1700, estimates a study published in Scientific Reports.
Global space for Asian elephant habitats has been in rapid decline since the 1700s, a new report reveals. More than 3 million square kilometers of the Asian elephant’s historic habitat range has been lost in just three centuries and may underlie present-day conflicts between elephants and people.
