Scientists have found that more finely ground coffee beans lead to weaker espresso due to uneven extraction. They used a simple mathematical model to split the coffee into two regions and examined how the uneven flow affected the brewing process. This uneven flow persisted in different parts of the coffee bed, affecting the taste of … Read more
Ultraluminous X-ray sources are objects that shine 10 million times as brightly as the Sun. Scientists say they are too bright to exist because they break the Eddington limit. A new study confirms the brightness of ULX – the mystery of how it exists remains unsolved. Loading Something is loading. Thanks for signing up! Access … Read more
Stars can be seen with the naked eye, but planets orbiting other stars are incredibly difficult to see, even with the most powerful telescopes ever made. It wasn’t until 1992 that astronomers imaged an exoplanet, meaning a planet in another solar system; Before that, some astronomers thought that our solar system might be unique and … Read more
Qizong Liang, a PhD candidate at Zila and from the Department of Physics at the University of Colorado Boulder, demonstrated how the laser-based breathalyzer works in Yeh’s lab at Zila. Finally, the system can be miniaturized for “health monitoring on the go.” Credit: Patrick Campbell/CU Boulder. Credit: CU Boulder With each breath, humans exhale more … Read more
A meteorite the size of an iconic New Jersey pork roll sandwich slammed into a home in Hopewell Township, New Jersey on Monday, smashing through the roof and ceiling before landing on a hardwood floor, according to local officials. According to local CBS affiliate KYW, the meteor managed to impact Earth and hit a house … Read more

This is an artist’s impression of a runaway supermassive black hole. Researchers at the IAC have discovered that the unusually thin structure of stars may actually be a galaxy, rather than the trail left by an escaping supermassive black hole.
