Under warming conditions, Arctic wolf spiders’ tastes in prey might be changing, according to new research by biologist Amanda Koltz in Arts & Sciences — initiating a new cascade of food web interactions that could potentially alleviate some impacts of global warming.

Researchers in physics in Arts & Sciences at Washington University in St. Louis are working out a theory of thermodynamics in quantum physics and finding some interesting results, including “negative information.”

Schoolwide efforts are among the threads weaved into the fabric of an Olin Business School MBA program ranked No. 4 in the world for women, according to a Financial Times analysis — placing it behind only Stanford and the University of California, Berkeley among U.S. universities, and China’s Shanghai Jiao Tong, but just ahead of Harvard.

Mickey and Debbie Stern, longtime supporters of Washington University in St. Louis, have made a $1 million commitment to the Gephardt Institute for Civic and Community Engagement. The gift will support the Civic Scholars Program, a key Gephardt initiative that prepares undergraduate students to be civic leaders.

Researchers from the School of Medicine and other institutions have sequenced the whole genomes of more than 100 metastatic prostate tumors, revealing new information about what drives the aggressive forms of this cancer.

A payment system that provides financial incentives for hospitals that reduce health-care costs for Medicare patients did not lower costs as intended, according to a new study led by the School of Medicine.

Studying young children, researchers at the School of Medicine found that kids who possess tendencies toward perfectionism and excessive self-control are twice as likely as other children to develop obsessive-compulsive disorder (OCD) by the time they reach their teens.

Researchers at the School of Medicine have found that in five states that decriminalized marijuana, there was no corresponding rise in the drug’s use among young people. In addition, marijuana-related arrests declined significantly.

A team at Washington University in St. Louis has created a bacteria that uses photosynthesis to create oxygen during the day, and at night, uses nitrogen to create chlorophyll for photosynthesis. This development could lead to plants that do the same, eliminating the use of some — or possibly all — man-made fertilizer, which has a high environmental cost.

New School of Medicine research indicates an investigational therapy for an inherited form of ALS extends survival and reverses signs of neuromuscular damage in mice and rats.
