Data highways for quantum information

Researchers at Vienna University of Technology have demonstrated experimentally that ultra-thin glass fibers can store quantum information long enough to be used for entangling atoms hundreds of kilometers apart. This is a fundamental building block for a global fiber-based quantum communication network.

Older adult clumsiness linked to brain changes

New research from Washington University in St. Louis suggests that older adults use less effective reference frames to visualize nearby objects, leading to difficulties with daily tasks like dialing phones and grasping objects. This study sheds light on the cognitive changes associated with aging and their impact on hand-eye coordination.

New analysis yields improvements in a classic 3-D imaging technique

Research at Curtin University has enabled major improvements in the widely used century-old 3D printing technique Anaglyph printing. The team targeted crosstalk problems visible as ghost-like shadows and found potential solutions by changing cyan ink, optimizing glasses and light sources, and using improved image processing algorithms.

Do-it-yourself invisibility with 3-D printing

Using 3D printing, researchers have created a simple and inexpensive way to produce plastic cloaks that can deflect microwave beams, making them appear invisible. The technique involves designing algorithms to create holes in the cloak, which allows it to suppress scattering from objects, effectively making them invisible.

Influence in times of crisis: How do men and women evaluate precarious leadership positions?

A study published in Psychological Science found that women are less likely to accept precarious leadership positions but more sensitive to social resources. Men, on the other hand, focus on financial resources. The researchers suggest that societal expectations about gender and leadership play a key role in driving these evaluations.

Expalination for ball lightning

Australian scientists unveil new mathematical theory explaining ball lightning, citing ion accumulation on glass windows as key factor. The theory suggests a driving electric field of about a million volts is required to form a ball discharge.

Glass shape influences how quickly we drink alcohol

Researchers at University of Bristol found that participants drank more slowly from curved 'beer flute' glasses than straight-sided glass containing lager, suggesting curved glasses compromise ability to gauge liquid levels and pace drinking. This could have positive impact on reducing intoxication and excessive drinking.

How geckos cope with wet feet

Researchers discovered that geckos have trouble sticking to smooth, wet surfaces when their feet get wet. The animals' toes produce a water-repellent layer, which interferes with their adhesive mechanism. However, once the lizards' feet dry, they can regain their grip and walk on wet surfaces.
