Requiem for an ancient tongue worm

Researchers have discovered a 425-million-year-old fossil of an ancient tongue worm parasite, providing significant insights into the origins of parasitism. The new species, Invavita piratica, is remarkably well-preserved and has been found attached to its host animal, an ostracod, in Herefordshire, England.

New biotechnology for high efficiency purification of live human cells

Researchers have developed a new technology that uses synthetic microRNA switches to purify live human cells with improved efficiency. The method, which involves identifying unique miRNAs for each cell type, shows promise for clinical applications and could lead to more homogeneous cell pools and better cell therapy outcomes.

The flight of the oryx

Research suggests that Doha's rise is driven by relational economic geography and urban development, with the Oryx antelope logo symbolizing its growth. However, the city lacks cohesive development plans and amenities for knowledge workers, which may hinder its success.

Memories influence choice of food

A study published in Neuron found that people tend to prefer snacks they can recall better, even if they are less attractive. The researchers used fMRI scans and mathematical modeling to understand how memory influences decision-making, revealing an increase in communication between the hippocampus and ventromedial prefrontal cortex.

Fine particulate air pollution associated with increased risk of childhood autism

A study by the University of Pittsburgh found an association between exposure to fine particulate air pollution and an increased risk of childhood autism. The research estimated that children exposed to higher levels of PM2.5 during pregnancy and early life were at a 1.5-fold greater risk of developing ASD.

Emoticons may signal better customer service ;)

A study found that customers rate customer service agents higher when they use emoticons in their responses, indicating a sense of emotional connection. Agents who respond quickly also receive positive ratings, as this creates a feeling of social presence.

Symbiosis turns messy in 13-year cicadas

A new study by CIFAR Fellow John McCutcheon's lab found that bacteria in cicada guts have split into many separate but interdependent species. This phenomenon leaves the cicadas reliant on a bloated genome and multiple species to create essential amino acids.

Penn researchers show that mental 'map' and 'compass' are two separate systems

Researchers at the University of Pennsylvania found that mice use separate systems to determine their location and direction, with environmental cues influencing place recognition but not heading retrieval. The study used identical rooms with different markings on the north wall, which allowed researchers to isolate the two processes.
