Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors publishing in the American Journal of Physics analyzed the pressure chamber’s Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), the length of time pressure builds, and the effects on output flow rate. Next, the authors plan to examine the physiological Windkessel involved in the heart-aorta system.

Eighteen years after NASA’s Stardust mission returned to Earth with the first samples from a known comet, the true nature of that icy object is coming into focus. Stardust collected material from Wild 2, a comet that likely formed beyond Neptune and currently orbits the sun between Mars and Jupiter. Painstaking analyses of the microscopic samples, recently described in the journal Geochemistry, have revealed a surprising truth about the comet’s origins and history, said Ryan Ogliore, an associate professor of physics in Arts & Sciences at Washington University in St.

Shuttlecocks, also known as birdies or birds, are traditionally made from duck feathers, but nylon shuttlecocks have become more widely used because of their superior durability. Their flight behavior, however, is far different from that of traditional feather birdies. In Physics of Fluids, scientists in India explored the aerodynamic performance of nylon shuttlecocks at various flight speeds. Through computational analyses based on two-way fluid-structure interactions, the team coupled equations governing air flow with equations determining skirt deformation of a shuttlecock in flight.

Scientists have confirmed possible evidence of a new elementary particle, the sterile neutrino. The results from the Baksan Experiment on Sterile Transitions (BEST) found that the germanium 71 yield was 20% to 24% lower than expected based on the intensity of the neutrino source and on scientists’ knowledge of how neutrinos are absorbed. This is consistent with earlier results on the so-called gallium anomaly.
