For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.

The jet power from this relatively close black hole-star system is equivalent to 10,000 suns, an international research team reported Thursday. They also tracked the jet speed: roughly 355 million mph (540 million kph)—half the speed of light.

Located 7,200 light-years away, Cygnus X-1 features not only a black hole—the first one ever identified more than a half-century ago—but a blue supergiant...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated, for the first time, a single quantum of vibrational energy interacting with a single atomic spin, seeding a pathway to quantum technologies that use sound as an information carrier, instead of light or electricity. The results are published in Nature.

Led by Marko Lončar, the Tiantsai Lin Professor of Electrical Engineering, the researchers engineered a nanometer-scale mechanical resonator around a single color-center spin qubit in diamond...

The European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) have signed a Memorandum of Cooperation to deepen collaboration in planetary defense, alongside a dedicated agreement for collaboration on the Rapid Apophis Mission for Space Safety (Ramses) to the near-Earth asteroid Apophis.

The agreements were signed on 7 May by ESA Director General Josef Aschbacher and JAXA President Hiroshi Yamakawa at the Embassy of Italy in Berlin, Germany, in the presence of European and Japanese institutional and industrial leadership. The event was hosted in collaboration with the Italian Space Agency (ASI), in light of ESA’s selection of OHB Italia as prime contractor for the Ramses mission.

The move builds on a joint statement from November ...

c Decaf even improved learning and memory, while caffeine boosted focus and reduced anxiety. Together, they show coffee works through multiple pathways beyond just caffeine.

Researchers at APC Microbiome Ireland, a leading research center at University College Cork, have taken a major step toward understanding how coffee benefits the body. For the first time, scientists have closely examined how coffee interacts with the gut-brain axis, the communication network that links the digestive system and the brain.

The findings, published in Nature Communications and supported by the Institute for Scientific Information on Coffee (ISIC), show that regularly drinking both caffeinated and decaffeinated coffee can shape the gut microbiome and influence mood and stress.

How Coffee Affec...
