Quantum key distribution (QKD) harnesses the power of quantum mechanics to securely transmit confidential information. When an outside source eavesdrops on a QKD transmission, the quantum states are affected. This dependably ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) with quantum mechanics and ...

Located on the island of Sicily, in Italy, Mount Etna is one of the world's most active volcanoes. Documentation of its many eruptions stretches back as far as 2,700 years ago, with the most recent occurring in June 2025. ...

Women are far more likely than men to end up with Alzheimer's disease (AD). This may, at least partially, be due to women's longer average lifespans, but many scientists think there is probably more to the story. It would ...

After existing quietly for over two decades on a Roscoe Village sidewalk in Chicago, a rodent-shaped indent became an internet sensation in 2024, when a tweet by comedian and writer, Winslow Dumaine, brought it into the public ...

On July 2, 2025, NASA's Fermi Gamma-ray Burst Monitor (Fermi-GBM) captured around three hours' worth of signals that appeared to come from the same source. When scientists compiled this data with signals picked up by multiple ...

Humans have about 400 odorant receptors (ORs), but scientists have had trouble finding ligands that match up with most of these ORs in lab settings—leaving them with a murky understanding of how certain smells are recognized ...

Many survey-based studies have been conducted to try to understand how happiness changes over a person's lifetime. While there have been a few different outcomes, the most common has been the U-shaped curve. This pattern ...

Naked mole-rats are one of the rare examples of eusocial mammals. Eusocial animal species are those in which a single female within the group is tasked with reproduction, along with a select group of males, while the rest ...

Not all stars are created equally. Astronomers believe that the first stars to form after the Big Bang were mostly made of only hydrogen and helium with trace amounts of lithium, as the heavier elements formed later on by ...

A new species of spider was recently discovered near a forested area in Nong Rong, Phanom Thuan, Kanchanaburi, in western Thailand. The spiders were presented to researchers at the Chulalongkorn University Museum of Natural ...

Flying manipulator robots have shown themselves to be useful in many applications, such as industrial maintenance or construction. Their utility in hard to reach or hazardous locations makes them particularly promising in ...

Neurons in the brain communicate with each other through synapses—connection points that allow the passage of electrical and chemical signals. In non-neuronal cells, direct cell-to-cell connections have been found to occur ...

Many people have probably seen birds picking up small pieces of man-made materials, like strips of a plastic bag or paper litter, and taking them into their nest. This behavior appears to be fairly widespread among birds. ...

Scientists have long been aware of the massive elliptical galaxy, M87. The galaxy was first observed in the late 18th century by Charles Messier, who cataloged objects in the sky specifically to avoid them when looking for ...
