Ultrafast plasmonics for all-optical switching and pulsed lasers

Plasmonics is playing a crucial role in advancing nanophotonics, as plasmonic structures exhibit a wide range of physical characteristics that are benefited by localized and intensified light-matter interactions. These properties are exploited in numerous applications, such as surface-enhanced Raman scattering spectroscopy, sensors, and nanolasers.

Image: Hubble spots the Spider Galaxy

This image from the NASA/ESA Hubble Space Telescope shows the gauzy-looking celestial body UGC 5829, an irregular galaxy that lies about 30 million light-years away. Despite the lack of observations of this relatively faint galaxy, UGC 5829 has a distinct and descriptive name: the Spider Galaxy. Perhaps its distorted galactic arms with their glowing, star-forming […]

Hubble sees new star proclaiming its presence with cosmic light show

FS Tau is a multi-star system made up of FS Tau A, the bright star-like object near the middle of the image, and FS Tau B (Haro 6-5B), the bright object to the far right that is partially obscured by a dark, vertical lane of dust. These young objects are surrounded by the softly illuminated […]

Why scientists are making space data into sounds

When you travel somewhere where they speak a language you can’t understand, it’s usually important to find a way to translate what’s being communicated to you. In some ways, the same can be said about scientific data collected from cosmic objects.

Building ChatGPT-style tools with Earth observation

Imagine being able to ask a chatbot, “Can you make me an extremely accurate classification map of crop cultivation in Kenya?” or “Are buildings subsiding in my street?” And imagine that the information that comes back is scientifically sound and based on verified Earth observation data.

Entanglement entropies of nuclear systems found to grow as the volume of those systems

Entanglement is what Einstein called “spooky action at a distance.” It is a key part of what distinguishes quantum mechanics from our everyday experience. In quantum mechanics, scientists use a measurement called entanglement entropy to quantify the amount of the entanglement between two subsystems—for example, between a system being studied and its environment.

New DNA tests on 2,000-year-old Elongated Paracas Skulls changes history

Among other results, researchers have found that the mystery skulls which date back at least 2,000 years have European and Middle Eastern origins. “If these results hold,” history of the migration of people to the Americas is far more complex than we have been told previously.” Brien Foerster. Elongated skulls on display at Museo […]
