Short, intensive workouts can help fight bowel cancer

As many of us embark on an exercise or gym routine for the new year, research reveals that just 10 minutes of intense exercise could help fight cancer.

Short bursts of energetic activity can trigger rapid molecular changes in the bloodstream, shutting down bowel cancer growth and speeding up DNA damage repair, a new study has shown.

Researchers at Newcastle University have found that exercise increases the concentration of several small molecules in the blood—many linked to reducing inflammation, improving blood vessel function, and metabolism.

When these exercise-induced molecules were applied to bowel cancer cells in the lab, the activity of more than 1,300 genes was altered, including those involved in DNA repair, energy production, and c...

Space mice come home and start families

Four mice went to space as astronauts. One came back and became a mother. And that simple fact might matter more than you’d think for humanity’s future beyond Earth.

On 31 October, China launched four mice numbered 6, 98, 154, and 186, aboard the Shenzhou-21 spacecraft to the country’s space station, roughly 400 kilometers above Earth. For two weeks, the rodents lived in microgravity, exposed to space radiation and the peculiar conditions of orbital life. They returned safely on 14 November. Then, on 10 December, one of the females gave birth to nine healthy pups.

In a previous study, sperm from mice that had been in space had been used to fertilize female mice back ...

Sudden breakups of monogamous quantum couples surprise researchers

two layers of a chemical structure lie above each other with black balls hovering on top. On the top layer, there is a cyan ball with a white ball in the corresponding layer below
An exciton forms when an electron pairs up with a hole—a mobile particle-like void in a material where an electron is missing from an atom. When paired up as an exciton, a hole and electron normally travel around together as an exclusive couple, but a new experiment probes what happens when conditions in a material break up the pair. In the image, a hole (grey sphere) resides in the bottom layer of a stacked material and is paired to an electron in the top layer (cyan sphere). None of the electrons present in the top layer (black spheres) are willing to share a spot in the material with each other or the electron in the exciton. (Credit: Mahmoud Jalali Mehrabad/JQI)
