Stripped to the bone
Natural disasters can devastate a region, abruptly killing the species that form an ecosystem’s structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.

Sleep Problems? You May Have An Increased Risk of Stroke
People who have sleep problems may be more likely to have a stroke, according to a study published in the April 5, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. Sleep problems included getting too much or too little sleep, taking long naps, having poor quality sleep, snoring, snorting and sleep apnea. In addition, those who had five or more of these symptoms had an even greater risk of stroke. The study does not show that sleeping problems cause stroke. It only shows an association.

NASA scientists are using neutrons at Oak Ridge National Laboratory to study moon rocks collected from the Apollo space missions. The samples are made of dust and rock fragments that combined and struck the moon’s surface possibly billions of years ago. As plans to travel to Mars progress, insights into the rocks could reveal more about the formation of the solar system and where water might be found on the moon.
A Novel Way to Get to the Excited States of Exotic Nuclei
Researchers developed a novel approach that observes dissipative scattering reactions to investigate discrete energy levels in an excited exotic nucleus. These energy levels are the nucleus’ unique fingerprint. The researchers observed unusual excited levels in calcium-38. These levels appear to be due to the simultaneous excitation of several protons and neutrons.

Detectan cuásares duales brillando en el centro de galaxias en fusión
Utilizando una serie de telescopios en tierra y el espacio, que incluía a Gemini Norte en Hawai‘i, los astrónomos descubrieron un par de cuásares sumamente energéticos que se encuentran muy unidos, un signo distintivo de un par de galaxias fusionadas. El evento ocurrió cuando el Universo tenía sólo tres mil millones de años, lo que da cuenta de la evolución de las galaxias en el “mediodía cósmico”, un período en la historia del universo en el que las galaxias experimentaron violentas explosiones de formación estelar. Esta fusión representa un sistema a punto de convertirse en una galaxia elíptica gigante.
Dual Quasars Blaze Bright at the Center of Merging Galaxies
Astronomers using an array of ground- and space-based telescopes, including Gemini North on Hawai‘i, have uncovered a closely bound duo of energetic quasars — the hallmark of a pair of merging galaxies — seen when the Universe was only three billion years old. This discovery sheds light on the evolution of galaxies at “cosmic noon,” a period in the history of the Universe when galaxies underwent bursts of furious star formation. This merger also represents a system on the verge of becoming a giant elliptical galaxy.
