Cancer biologists discover a new mechanism for an old drug

Doctors have long believed the cancer drug 5-fluorouracil works by damaging the building blocks of DNA, but researchers have now found that in certain cancers, it kills cells by interfering with RNA synthesis. The findings could help researchers design better drug combinations for colon and gastrointestinal cancers.

Space oddity: Most distant rotating disc galaxy found

Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of galaxy formation, such early galaxies are expected to appear more chaotic.

After injury, these comb jellies can fuse to become one

Researchers have made the surprising discovery that one species of comb jelly (Mnemiopsis leidyi) can fuse, such that two individuals readily turn into one following an injury. Afterwards, they rapidly synchronize their muscle contractions and merge digestive tracts to share food.

What happens in the brain when a person with schizophrenia 'hears voices'?

Auditory hallucinations are likely the result of abnormalities in two brain processes: a 'broken' corollary discharge that fails to suppress self-generated sounds, and a 'noisy' efference copy that makes the brain hear these sounds more intensely than it should, according to a new study.
