Even Tiny Amounts of Altruism Can Stop Epidemics, Game Theory Study Finds
A new mathematical study has found that people don’t need to be saints to justify staying home when they’re sick. In fact, caring about others even a tiny amount — valuing your own life as roughly equivalent to 100,000 strangers
Pro-gun PACs spike spending 2,820% after fatal school shootings near Election Day, Stanford study finds

Difficult people in your social circle may be accelerating your biological aging, study finds
People who make your life difficult may be doing more than ruining your day — they could be making you age faster at the molecular level. A new study from researchers at New York University, Utah State University, the University
Physicists show electric charges can be accelerated without producing radiation
One of the oldest rules in physics — that accelerating an electric charge always produces radiation — turns out to have an exception. A team of physicists has shown that in quantum mechanics, it is possible to accelerate a charged
High temperatures linked to fewer male births in Africa and India, but for very different reasons
A sweeping new study analysing nearly five million births across sub-Saharan Africa and India has found that high temperatures during pregnancy are linked to fewer male births — and the reasons differ dramatically between the two regions. Researchers from the
