Fly vs. wasp: Stealing a defense move helps thwart a predator

Researchers found that fruit flies have stolen a toxin-producing gene from bacteria to defend against parasitic wasps, which can turn fly larvae into surrogate wombs for baby wasps. This discovery highlights the importance of horizontal gene transfer in animal evolution and suggests it may be more common than previously thought.

Evolution of fast-growing fish-eating herring in the Baltic Sea

A new study found that a unique population of large fish-eating herring has evolved in the Baltic Sea, exhibiting faster growth rates and lower levels of pollutants. These herring have adapted to the brackish water by switching from plankton-eating to a fish diet, with potential benefits for human consumption.

Emergency department physicians vary widely in their likelihood of hospitalizing a patient, even within the same facility

A new study found that emergency department physicians differ in their likelihood of hospitalizing patients, with those who admit more patients being discharged sooner but not less likely to die. The study suggests that differences in physician decision-making drive these variations, rather than patient health.

Burning cancer's bridges

Researchers discovered that aggressive breast cancer prompts nearby immune cells to build 'molecular bridges' between themselves, suppressing the immune response. An antibody treatment that blocks these bridges was shown to restore the immune system's ability to attack with force, inhibiting tumor growth in a mouse model.
