This study provides new insights into metformin’s effect on the molecular mechanisms inside cells and why it reduces proliferation of cancer cells, emphasising the role of miRNAs in colorectal cancer.

The authors suggest their findings highlight the potential for developing RNA therapeutics for cancer prevention and treatment and possibly for targeted interventions. Although there are several challenges in the field of miRNA therapeutics, this study could signal another step in their development as potential cancer treatments.

Now, however, astronomers Fan Zou and W. Niel Brandt, both of Penn State University, have led a team that connected the two mechanisms of black-hole growth from observations and simulations. The results may provide some answers at last.

“A very big question is how do these supermassive black holes grow so massive?” said Zou while presenting their work at the 244th meeting of the American Astronomical Society in Wisconsin… “To address that, we need to track the overall growth history of these supermassive black holes.”

Chinese scientists have made a groundbreaking milestone in nuclear fusion. They have announced a major achievement in discovering an advanced magnetic field structure “for the first time in the world” using the Huanliu-3 (HL-3) tokamak, also known as China’s “artificial sun.”

The discovery is the result of the first round of international joint experiments conducted on the HL-3 tokamak, a project that opened to global collaboration at the end of 2023.

Most distant spacecraft, #Voyager1, is now returning data from all four science instruments for the first time following a technical issue last November.


NASA’s Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.

The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and status of the spacecraft. On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data. Two of the four science instruments returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data.

The four instruments study plasma waves, magnetic fields, and particles. Voyager 1 and Voyager 2 are the only spacecraft to directly sample interstellar space, which is the region outside the heliosphere — the protective bubble of magnetic fields and solar wind created by the Sun.
