Collaboration controls killers

Scientists at St. Jude Children's Research Hospital studied enhancers that regulate Foxp3 gene expression to control effector and killer T cells. They found that these enhancers work together to curb the immune cells' activity, ensuring they only attack cancer cells.

Plant competition during climate change

Researchers investigated plant competition under dual stressors of extreme drought and invasive species, finding dynamic interactions that amplify or buffer each other. Cork oak trees surprisingly recover better than expected after extreme drought when the invasive gum rockrose is also affected.

SLAS Discovery's June issue on synthetic biology available now

The June edition of SLAS Discovery features the cover article on developing high-throughput biochemical assays to assess small molecule impact on SARS-CoV-2 nonstructural protein 14. The issue also includes nine original research articles, covering topics such as HIV latency reversal, kinase inhibitors, and drug combination screening.

Self-excising designer proteins report isoform expression

Scientists at Helmholtz Zentrum München developed a new bioengineered reporter system called EXSISERS, enabling non-invasive observation of fundamental cellular processes. The system detects specific protein isoforms being translated, with potential applications in neurodegenerative diseases like Parkinson's.

Corals tell Arabian Sea story of global warming

Researchers found that global warming is causing changes to the Arabian Sea upwelling, which could impact commercial fishing, regional climate, and socioeconomics. The study used coral fossils to analyze seawater temperature and salinity changes over a 1,000-year period.

Getting they/them pronouns right

A recent UNC-Chapel Hill study found that explicitly stating a person's preferred pronouns can improve understanding and interpretation of those pronouns. The study showed that participants were more likely to correctly interpret singular 'they' pronouns when they were explicitly told a person uses they/them pronouns.

Bacteria are connected to how babies experience fear

A new study from Michigan State University found that infants' gut microbiomes are associated with their fear responses, which can be indicators of future mental health. The researchers discovered that specific features of the gut microbiome, such as uneven balances of bacteria, were linked to stronger fear reactions.

Life stage differences shield ecological communities from collapse

A new study reveals that juvenile-adult differences shield ecological communities from collapse. The research shows that variations within species are crucial for community stability, leading to the stabilization of ecosystems. Differences in size and growth rates between juveniles and adults contribute to these effects.
