A newly detected X-ray transient may reveal the first direct evidence of an intermediate-mass black hole consuming a white dwarf. A newly observed cosmic outburst is giving astronomers a rare glimpse ...

The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials ...

If you are worried and want to know how to fast-track and give the final push to your preparation, here are some suggestions on important topics, formulas, high-weightage units, along with what you ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

Computer scientists Maria Apostolaki, Benjamin Eysenbach, and Yasaman Ghasempour; chemists William Jacobs and Erin Stache; physicist Isobel Ojalvo; and mathematician Bartolomeo Stellato are members of ...

For the modern technology leader, the quest for peak performance has traditionally been a matter of chemistry, an endless ...

Magnetic fields thread through galaxies, stretch across cosmic voids, and shape the behavior of charged particles over millions of light-years. Yet their origin remains one of the most stubborn ...

A faint flash of infrared light in the Andromeda galaxy was emitted at the birth of a stellar-mass black hole – according to a team of astronomers in the US. Kishalay De at Columbia University and the ...

With engineered microstructures, metamaterials enhance stealth capabilities, enabling advanced wave manipulation for improved military platform invisibility.

The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at ...

By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a superconducting material. The kind of light you use can reveal very different things ...
