Tech Xplore / Why 'zero-knowledge encryption' may not stop password theft if servers are hacked

People who regularly use online services have between 100 and 200 passwords. Very few can remember every single one. Password managers are therefore extremely helpful, allowing users to access all their passwords with just ...

Phys.org / Why some extracellular vesicles work better: A safer path for protein and gene delivery

Extracellular vesicles (EVs) are tiny membrane-bound particles released by cells to transport proteins and other molecules to neighboring cells. Because of this natural delivery ability, EVs have attracted growing interest ...

Phys.org / Antarctica sits above Earth's strongest 'gravity hole.' Now we know how it got that way

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest beneath the frozen continent ...

Phys.org / Amazon deforestation raises surface temperature by 3°C during dry season, satellite data show

Deforestation in the Amazon is causing significant regional changes in climate compared to areas with forest cover above 80%. The loss of vegetation leads to an increase in surface temperature, a decrease in evapotranspiration, ...

Phys.org / Optical switch protocol verifies entangled quantum states in real time without destroying them

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A breakthrough by researchers ...
