Bacterial drug resistance studied by robotic E. coli evolution


Experimentally evolving E. coli under pressure from a large number of antibiotics was able to identify constraints underlying evolved drug resistance.

Engineering crop immunity from a receptor in pomelo fruit


Synthetic receptors derived from the pomelo fruit can help crops become immune to thousands of pathogens.

Organic nitrogen in soil helps crop growth


Scientists used a multi-omics analysis to show that soil solarization helps crops grow because it increases organic nitrogen in the soil.

Boosting betaine may be a treatment for schizophrenia


Supplementing model mice with glycine betaine (trimethylglycine), a compound originally derived from beets, can alleviate symptoms of schizophrenia.

Bye-bye microplastics: new plastic is fully ocean-degradable


A new bioplastic that dissolves in saltwater — no more pesky microplastics!

Social contact-seeking behavior and loneliness in the brain


Levels of the peptide amylin in the brain are related to loneliness; activating amylin neurons in the MPOA drives isolated mice to seek social contact.

Proton and antiproton still seem identical


Using a novel two-particle measurement method, scientists have measured the magnetic moment of the antiproton at a precision 350 times higher than any previous measurement.

Microbial infections are a parasitic plant’s dream


Parasitic plants use quinones produced by their host to attack. Now we know that crops produce quinones as an immune response against microbial infection. How can we protect crops from both kinds of attack?
