Animals will often put their lives on the line for reproduction, even if it comes at the cost of being the wrong temperature. Thermal biology co-adapts with the traits favored by sexual selection, including things like courtship displays, ornamental coloration and enlarged weapons like horns or claws.
On Aug. 2, voters in Arizona, Kansas, Michigan, Missouri and Washington will vote in their states’ primary elections. Thirteen more states will hold primary elections through August and September.In many districts where the general election isn’t competitive, the outcomes of these primary elections likely will decide who wins in November.

By analyzing noble gas isotope data, a scientist determined that the ancient plume mantle had a water concentration that was a factor of 4 to 250 times lower when compared with the water concentration of the upper mantle. The resulting viscosity contrast could have prevented mixing within the mantle, helping to explain certain long-standing mysteries about Earth’s formation and evolution.

Researchers from Washington University in St. Louis received a grant from the National Science Foundation to determine the thermal and compositional structure of Antarctica using seismic, gravity and topography data and petrological modeling.
Yevgeniy Vorobeychik doesn’t know exactly what sentience is. Since he’s an engineer, not a philosopher, Vorobeychik can’t say what it’s like to be a bat or a tree or a rock. He can’t quantify the importance of embodiment to consciousness. He’s not even sure that there’s an inherent problem with people reacting to an artificial intelligence in ways similar to how they react to other people.
Experts from Washington University in St. Louis offer perspectives on the Supreme Court’s decision to overturn Roe v. Wade and the impact it will have on American law, people and politics.
While the ruling in the Maine case is unsurprising giving the court’s recent decisions around freedom of religion, some of the rhetoric around the case misrepresents the role of constitutional protections for religion in a pluralistic society, said John Inazu, expert on law and religion at Washington University in St. Louis.
