Advanced MRI data set maps adolescent brain development
Researchers have created a large, openly available neuroimaging resource from more than 24,000 MRI scans of over 10,000 adolescents, providing a view of how the brain's wiring develops during adolescence. Using advanced, ...

Common deworming drug helps restore lung cancer's sensitivity to targeted therapy in mice
A form of lung cancer, which is found in about 10%–15% of Western patients and 40%–50% of Asian patients, is driven by a mutation in the epidermal growth factor receptor (EGFR) gene. Gefitinib is a go-to drug that shuts down ...

A gut microbe makes a fatty acid that cuts artery plaque in half in mice
A common gut bacterium produces a molecule that slows cholesterol production in the liver. When researchers gave the molecule to mice prone to artery disease, the animals developed roughly half as much fatty plaque as untreated ...
Reversing age by reprogramming gene expression networks
Every organ and tissue progressively loses function and integrity as it ages. In fact, researchers have identified "hallmarks of aging" that not only present specific processes impacted by age, but are also thought of as ...

AI misuse and nuclear famine could threaten humanity's survival before 2100
The fate of global health does not rest on any single disease. True preparedness means pairing the fight against illness with strength in finance, climate, defense and security. The COVID-19 pandemic, which brought the world ...
Reversible genetic switches could give cancer immunotherapy more precise control
A genetic switch that activates immune cells as they fight tumors: this is the new strategy developed by an international research team coordinated by Velia Siciliano at the Istituto Italiano di Tecnologia (IIT—Italian Institute ...

What if mosquito saliva holds the key to better fighting Zika, dengue and West Nile viruses?
Mosquitoes do more than simply transmit the viruses they carry: Their saliva may actively help these viruses establish infection in the body from the very moment of the bite. This is the finding of a study conducted by a ...

Trapping cancer-driving DNA rings outside cell nucleus silences their genes, researchers find
Cells from rapidly growing, highly metastatic tumors often contain numerous rings of extrachromosomal DNA (ecDNA). This circular DNA frequently carries oncogenes—genes that promote cancer. Researchers have long sought vulnerabilities ...
