Hybrid material confirms antiferroelectricity can coexist with switchable polarization‎

Many of the advanced electronic components surrounding us in everyday life rely on polar materials to function. Polar materials have an uneven distribution of electric charge. This gives them a positive and a negative side even in the absence of an external electric field. The most important among these are ferroelectric materials, in which the direction of polarization can be reversed by applying an electric field.

Climate change, urban growth fuel Lagos flooding‎

After hours of torrential overnight rain lashed Lagos recently, church pastor Samuel Akpan spent most of the next day bailing water from his flooded parsonage in an upscale district of Nigeria's commercial capital.

Pump that recreates human heartbeat blood flow on lab chips inspired by an accordionist‎

For more than 25 years, lab-on-a-chip technology has allowed researchers to model human organs and blood vessels using real human cells in artificial microscopic environments. These microphysiological systems (MPS) may replicate human cells and mimic organs or even full organ systems under numerous conditions. They have become key to studying everything from heart disease to the effectiveness of new drugs. However, they have been held back by one major limitation: an inability to accurately re-create the blood flow waveforms generated by the human heart.

Cellular transporter protein essential for nutrient absorption in pathogenic fungi may offer new treatment approaches‎

They are the cell's "gatekeepers": specialized proteins, known as transporters, selectively control which substances enter a cell and which do not. Researchers at the University of Münster and the National and Kapodistrian University of Athens have investigated these transporters in a specific case: the UapA transporter of the model fungus Aspergillus nidulans. The findings are not only relevant to cell biology but could also offer new approaches to treating fungal infections.

Scientists create stable 'boron graphene' and uncover quantum liquid crystal state‎

Graphene has long been regarded as one of the most promising materials for future electronics, but its relatively weak electron interactions have limited its potential for applications such as high-temperature superconductivity. Now, researchers from Tohoku University have overcome a major obstacle by creating a stable version of the long-sought "boron graphene" on the surface of a three-dimensional crystal, revealing a new quantum state that could lead to more energy-efficient electronic devices. The findings were published in Science Advances on July 2, 2026.
