A diagnostic tool that can differentiate between healthy and cancerous tissue, called the MasSpec Pen, has been tested for the first time in surgery.

An important step in programmed cell death is the binding of a protein (called cytochrome c) to the membrane of mitochondria. Scientists have now discovered that cytochrome c is partly unfolded during this important step and they can pinpoint which parts of the protein are folded or unfolded.

About one-third of children diagnosed with severe malaria may instead have an alternative cause of illness, but simple blood tests could help researchers distinguish between the two and speed up research on new treatments.

It might be worth exploring stool transplant to treat COVID-19 infection, suggest doctors in a letter publishedin the journal Gut, after they used the procedure in two patients to prevent the recurrence of another bacterial infection.

Scientists have shown that brown trout are at risk of becoming addicted to methamphetamines that enter the water supply. The new study is published in the Journal of Experimental Biology.

A study suggests that early experiences may have a larger effect on our mood than more recent events. These findings could help produce mood interventions tailored to individual patients.

An observational method called human social sensing can elicit information that is difficult to obtain from digital trace data. Researchers are now using this method with the global "Covid Trends & Impact Survey" to predict the course of the pandemic.
