Apple iPhone 17 Pro delivers top performance and advanced cameras for field documentation, data collection, and secure research communications.

Your eyes talk to your ears. Scientists know what they’re saying.

Researchers at Duke University have discovered that subtle ear sounds can be decoded to pinpoint where someone's eyes are looking. By analyzing these sounds, the team was able to estimate the movement of the eyes and predict what the waveform of the ear sound would look like.

Authors of new book reveal the artist behind architect Le Corbusier

The book uncovers previously unpublished documents and color photographs that shed new light on Le Corbusier's architectural oeuvre. It explores his aesthetic principles, including the use of exposed concrete (béton brut), and examines how he defined artistic quality in construction sites.

Gender, time of day affect response to vaccination

Researchers found that men vaccinated in the morning showed strongest immune response to both hepatitis and influenza vaccines. The study's results have implications for vaccination timing, suggesting that adults could be vaccinated at specific times of day to increase their protection against flu.

Hard work while fatigued affects blood pressure

Research found that exhausted individuals experience larger blood pressure increases when attempting tasks, even if they perceive success as achievable. Chronic fatigue can amplify effort and lead to elevated blood pressure, increasing the risk of hypertension and heart disease.

A picture does not automatically activate a thousand words

Researchers found that visual cues, such as pictures of objects, can elicit significant brain activity, but this response differs from the electrical signal triggered by verbal cues like words. The study suggests that image processing and word processing may involve separate neural networks.
