Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a ...

Light speckle fluctuations, a noninvasive proxy for cerebral blood flow index (CBFi), are quantified by diffuse correlation spectroscopy. However, this conventional technique provides marginal brain ...

This article reviews the use of Raman spectroscopy in a series of case studies to quickly identify the iron oxide compound(s), including magnetite and hematite, on the surface of representative ...

A tiny burst of motion inside a molecule may be enough to shove an electron across a solar material almost as fast as nature permits. That is the striking result from a University of Cambridge-led ...

Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a source of coherent light on ...

While fuel cells generate clean energy, fuel cell sensors generate precise measurements and are a gold standard for breath alcohol analysis.

Astronomers have successfully mapped the cold gas at the Milky Way's center, offering unprecedented insight into our solar system's origins.

Randomness favours the worm becoming free because its head can move in many ways that will help to propel it forwards, but only one that would push it backwards. Because of the intrinsically random ...

Better mRNA release inside cells boosts vaccine and gene editing performance, enabled by redesigned lipid molecules that grip ...

A single flat metalens now handles both excitation and fluorescence collection for diamond quantum sensors, enabling ...

And all because copper is now super expensive.

Scientists have discovered that electrons in solar materials can be launched across molecules almost as fast as nature allows, driven by tiny atomic vibrations.
