An international team of scientists has observed the narrowing of a quasar jet for the first time by using a network of radio telescopes across the world...

Laboratory research finds a low-protein diet can enhance standard treatment for colon cancer. A dietary change could be a key to enhancing colon cancer treatment, a new study from the University of Michigan Rogel Cancer Center finds.

Cancer cells need nutrients to survive and grow. One of the most important nutrient sensing molecules in a cell is called mTORC1. Often called a master regulator of cell growth, it allows cells to sense different nutrients and thereby grow and proliferate. When nutrients are limited, cells dial down nutrient sensing cascade and turn off mTORC1.

While mTORC1 is known to be hyperactive in colon cancer, the k...

Doubling the quantum information space of commercial technologies, this new chip is better suited for real-world application. Researchers at Penn Engineering have created a chip that outstrips the security and robustness of existing quantum communications hardware. Their technology communicates in “qudits,” doubling the quantum information space of any previous on-chip laser.

The JWST just scored another first: a detailed molecular and chemical portrait of a distant world’s skies. New observations of WASP-39 b reveal a never-before-seen molecule in the atmosphere of a planet – sulfur dioxide – among other details.

The telescope’s array of highly sensitive instruments was trained on the atmosphere of a “hot Saturn” – a planet about as massive as Saturn orbiting a star some 700 light-years away – known as WASP-39 b. While JWST and other space telescopes, including Hubble and Spitzer, previously have revealed isolated ingredients of this broiling planet’s atmosphere, the new readings provide a full menu of atoms, molecules, and even signs of active chemistry and clouds.

“The clarity of...
