Decades after his voyage on the HMS Beagle, Charles Darwin became fascinated by why plants move as they grow -- spinning and twisting into corkscrews. Now, more than 150 years later, a new study may have solved the riddle.

A new study has identified diet-derived molecules called metabolites as main drivers of young-onset colorectal cancer risk, especially those associated with red and processed meat. The report, which analyzed metabolite and microbiome datasets, highlighted that one of the best ways a younger (less than 60 years) adult can prevent colorectal cancer is to discuss their diet with their doctor.

A new study has found galaxies with more neighbors tend to be larger than their counterparts that have a similar shape and mass, but reside in less dense environments. The team, which used a machine-learning algorithm to analyze millions of galaxies, reports that galaxies found in denser regions of the universe are as much as 25% larger than isolated galaxies. The findings resolve a long-standing debate among astrophysicists over the relationship between a galaxy's size and its environment, but also raise new questions about how galaxies form and evolve over billions of years.

Conventional cancer drugs work by triggering apoptosis, that is programmed cell death, in tumor cells. However, tumor cells have the ability to develop strategies to escape apoptosis, rendering the drugs ineffective. A research team now describes a new mechanism of action that kills cancer cells through ferroptosis.

Caesarean section recipients are usually given prophylactic antibiotics just before the procedure to prevent later infections at the surgical site. But there have been concerns about whether these antibiotics may have a negative impact on newborns and their microbiomes if the drugs travel through the umbilical cord and reach the baby before the cord is cut. Now, a study has confirmed that although these antibiotics can cause subtle changes to the infant microbiome, they are much less significant than the impact of how the babies are fed.

Researchers unveiled an approach to drug discovery that could revolutionize how we understand and treat diseases. Their commentary explains the limitations of studies using traditional mouse models and proposes using genetically diverse mice and mouse and human cells to better predict human responses to drugs and diseases.
