Human intelligence: have we reached the limit of knowledge?

Despite huge advances in science over the past century, our understanding of nature is still far from complete. Not only have scientists failed to find the Holy Grail of physics—unifying the very large (general relativity) ...

Neutrino produced in a cosmic collider far away

The neutrino event IceCube 170922A, detected at the IceCube Neutrino Observatory at the South Pole, appears to originate from the distant active galaxy TXS 0506+056, at a light travel distance of 3.8 billion light years. ...

Hubble takes closer look at not-so-'dead' neighbor

Many of the best-loved galaxies in the cosmos are remarkably large, close, massive, bright, or beautiful, often with an unusual or intriguing structure or history. However, it takes all kinds to make a universe—as demonstrated ...

Producing dissipative coupling in hybrid quantum systems

As quantum objects are susceptible to their surrounding environment, quantum coherence and quantum states can easily be destroyed due to the impact of external signals, which can include thermal noise and backscattered signals ...

Naming of new interstellar visitor: 2I/Borisov

A new object from interstellar space has been found within the solar system, only the second such discovery of its kind. The object offers a tantalizing glimpse beyond the solar system, and raises some puzzling questions. ...

Blanket of light may give better quantum computers

Quantum mechanics is one of the most successful theories of natural science, and although its predictions are often counterintuitive, not a single experiment has been conducted to date of which the theory has not been able ...

Gesture as language: why we point with a finger

Pointing at an object… in one sense you might say that this simple gesture doesn't just replace a word, but that it is a word—perhaps the first word. We know that it and other such gestures play a fundamental role in ...

Dip-coating: How to predict the thickness of thin films?

The immersion method of applying a coating to an object presents a central challenge: predicting the thickness of the layer that will cover the object. This question raises important financial issues for manufacturers. A ...
