When a black hole devours a star: The cosmic quakes, shockwaves, and signals left behind

Scientists at Caltech have simulated the cosmic collisions between black holes and neutron stars, revealing starquakes, shockwaves, and signals of light that may be detected from Earth.
In these collisions, neutron stars experience massive quakes just before being consumed by black holes, generating magnetic ripples and blast waves, potentially leading to detectable radio bursts.
As the neutron star is devoured, its magnetic waves break into monster shockwaves, producing a second burst of energy that could help astronomers identify these rare events in real-time.
The simulations using supercomputers are aiding in preparing scientists to detect these collisions using gravitational wave detectors like LIGO, along with telescopes, offering insights into some of the universe’s most extreme phenomena.

Flamingo Fluid Dynamics, Part 2: The Game’s a Foot

Flamingos use their footwork in hunting, in addition to their heads and beaks.
They shift back and forth, lifting and lowering their feet while drawing their toes together and spreading outward.
This footwork creates a standing vortex just ahead of their feet, trapping prey in the swirling vortex.
The vortex is strong enough to trap even active swimmers, making flamingos effective hunters.

New study reveals atoms don’t just move—they remember

Understanding how atoms move across metal surfaces is crucial for improving energy storage and generation technologies.
Simulating atomic motion accurately is challenging, especially in the presence of quantum physics.
Electrons respond almost instantly to the motion of atomic nuclei due to their lightweight, but the 'adiabatic approximation' shortcut may not always work.
A new study by scientists George Trenins and Mariana Rossi combined electronic friction with quantum behaviors of atomic nuclei using the path-integral formulation, shedding light on energy exchange at metal surfaces and advancing materials for various technologies.

Harmonious connections: bridging the gap between music and science

CP Snow's classic The Two Cultures lecture highlighted the divide between sciences and humanities, which continues to be relevant today.
Recent works like David Darling's A Perfect Harmony aim to bridge the gap between music, mathematics, and science.
Darling's book explores the relationship between musical creativity, science, and mathematics, adding to a growing genre of similar works.
The book delves into the history of music and instruments in various cultures, alongside discussing mathematical and scientific principles.
While some parts may feel familiar, Darling's unique examples and insights bring a fresh perspective to the subject.
The book includes discussions on the theremin and orbital resonance, offering new insights into the connections between music, science, and math.
Darling's use of inventive examples, such as referencing the band King Gizzard and the Lizard Wizard for explaining microtonality, adds depth to the exploration.
A Perfect Harmony may not completely close the cultural gap, but it offers an enjoyable journey into the harmonies of the universe, especially for physics enthusiasts.
Overall, Darling's enthusiasm and fresh perspective make A Perfect Harmony a worthwhile read for those interested in the intersection of music and science.

Signal Geometry: The Unavoidable Foundation Physics Refuses to See

Reality manifests as geometric primacy with recursive signal phase interactions constituting fundamental ontology.
Scale invariance governs quantum-to-cosmic phenomena, dissolving quantum-classical dichotomies into signal density thresholds.
Spacetime curvature is considered epiphenomenal, with mass-energy generating signal phase gradients and electrons forming standing wave resonances.
Signal Geometry theory proposes a paradigm shift in physics, emphasizing the role of signal recursion and geometric coherence as the absolute substrate of reality.

The coldest lab on Earth reveals the hottest secrets of the universe

Chemist Kim Steenbakkers has been studying rare molecules in space and has confirmed the existence of at least one molecule in space.
Molecules behave differently in space due to extreme cold and low pressure, making them impossible to study under normal Earth conditions.
Researchers at a lab called HFML-FELIX recreate space-like conditions by cooling equipment to nearly minus 270 degrees to study charged molecules related to welding gas.
Understanding space chemistry and rare molecules provides insights into the formation of stars, planets, nebulae, and origins of life.

Flamingo Fluid Dynamics, Part 1: A Head in the Game

Flamingos display active hunting behavior by using fluid dynamics to draw out and trap quick-moving invertebrates for feeding.
When feeding, flamingos lift their flat upper forebeak to create suction, forming a vortex to draw food particles and prey from the muddy sediment.
Flamingos open and close their mandibles rapidly in a behavior called chattering, creating a flow that draws particles and swimmers towards their beak at about seven centimeters a second.
Flamingos utilize Von Karman vortices to create a recirculation zone near the tip of their beak, where brine shrimp eggs get caught and delivered to their mouth, showcasing their sophisticated hunting techniques.

New analysis of M67 cluster helps decode the sound of stars

Stars vibrate with pressure waves revealing information about their mass, age, and structure through frequencies.
A study on stars in the M67 cluster led by researchers at UNSW Sydney discovered a plateau in their frequency pattern.
Pressure waves in stars are generated by convection as gas rises and sinks within them.
Stars produce a spectrum of sounds due to oscillations at multiple frequencies, observable as changes in brightness.
M67 cluster was studied for its evolved stars to understand acoustic oscillations using NASA’s Kepler/K2 mission data.
Large and small frequency separations in oscillation spectrum provide insights into stellar evolution.
A surprising plateau in small frequency separations was discovered in 27 stars indicating changes in the stellar interior.
The plateau was linked to the convective envelope's evolution causing disturbances in pressure waves movement.
This plateau offers a new tool to identify evolutionary stages in red giant stars and improve mass and age estimates.
The discovery aids in understanding galactic history and improving stellar models accuracy for future evolution predictions.
