Bright blazar reveals 433-day optical quasi-periodic oscillation across nine years

Matter behaves strangely under extreme conditions, and often, remnants of these behaviors are left behind even when conditions return to normal. The Trinity nuclear test in 1945 left behind such remnants, and now, 80 years after the explosion, researchers have identified another unique example of what happens when various materials are heated to temperatures exceeding 1,500 °C (2,730 °F) and put under pressures tens of thousands of times atmospheric pressure.

Every summer, beach closures disrupt families, harm local businesses, and raise public health alarms. Most of the time, the warning comes after it is already too late.

Quantum computers could someday solve pressing problems that are too convoluted for classical computers, such as modeling complex molecular interactions to streamline drug discovery and materials development.

Experiences in the first days and weeks of life can have a profound impact on humans—and birds. A new study led by Sage Madden, a graduate student in evolution and ecology at the University of California, Davis, shows how weather conditions and family dynamics affect the growth of barn swallow (Hirundo rustica erythrogaster) chicks.
