Parents have a new—and deadly—reason to sit down with their tweens and teens for a talk about drug abuse. The reason: fentanyl.
Un equipo científico detectó agua en el disco circumestelar de una protoestrella cercana gracias al Atacama Large Millimeter/submillimeter Array (ALMA). Es la primera vez que se observa agua depositándose en un disco protoplanetario sin que se produzcan cambios significativos en su composición. Este hallazgo permite suponer que el agua presente en nuestro Sistema Solar se formó miles de millones de años antes que el Sol.
Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk. The new observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) mark the first detection of water being inherited into a protoplanetary disk without significant changes to its composition. These results further suggest that the water in our Solar System formed billions of years before the Sun.
Hospitals still struggle to successfully implement enhanced recovery programs and may need more structured resources to boost compliance rates, according to findings published in the Journal of the American College of Surgeons (JACS).
Researchers at Universidad Carlos III de Madrid (UC3M) have created software and hardware for a 4D printer with applications in the biomedical field. In addition to 3D printing, this machine allows for controlling extra functions: programming the material’s response so that shape-changing occurs under external magnetic field, or changes in its electric properties develops under mechanical deformation.
Researchers have begun to explore the underlying neural activity of eating behaviours in fruit flies to better understand the motives that drive feeding.
It’s not just humans who enjoy eating shellfish, so do marine rays. They like to “crunch” on clams, which can sometimes take a big bite out of clammers’ profits. Using aerial and underwater videos, researchers assessed the ability of the whitespotted eagle ray to interact with clams housed within a variety anti-predator materials. Whitespotted eagle rays have strong jaws, plate-like teeth and nimble pectoral fins, which make them formidable and highly maneuverable predators of clams.

An international team of scientists has created a salad that contains ingredients that could be grown on spacecraft and provide optimum nutrition for astronauts heading into deep space.
In a new study, researchers used new technologies to remotely document, for the first time in the wild, the location and timing of shark birth. Named the Birth-Alert-Tag (BAT), this new satellite tag remained inside the uterus, along with the developing shark pups, until the mother shark gave birth and expelled the newborn pups, along with the BAT, into the surrounding water. The BAT then floated to the surface and transmitted to satellites the location of where the shark birth took place. The first of its kind, the BATs were successfully deployed in a tiger shark and scalloped hammerhead shark, documenting the location birth.
The time has come to create a new kind of computer, say researchers from John Hopkins University together with Dr Brett Kagan, chief scientist at Cortical Labs in Melbourne, who recently led development of the DishBrain project, in which human cells in a petri dish learnt to play Pong.
La Cámara de Energía Oscura, fabricada por el Departamento de Energía de EE.UU e instalada en el Telescopio de 4 metros Víctor M. Blanco de la Fundación Nacional de Ciencias (NSF por sus siglas en inglés) de EE.UU en el Observatorio Interamericano Cerro Tololo (Chile), un Programa de NOIRLab de NSF y el Observatorio AURA, captó los vestigios de la primera supernova registrada en la historia. El anillo de escombros de RCW 86 es todo lo que queda de una estrella enana blanca que explotó hace más de 1.800 años, cuando fue registrada por los astrónomos chinos como una “estrella invitada”.
The tattered shell of the first-ever historically recorded supernova was captured by the US Department of Energy-fabricated Dark Energy Camera, which is mounted on the National Science Foundation’s (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF’s NOIRLab. RCW 86’s ring of debris is all that remains of a white-dwarf star that exploded more than 1800 years ago, when it was recorded by Chinese stargazers as a ‘guest star’.
Rowena Roque, 46, was having a problem that many people can relate to: doing everything in her power to lose weight and get healthy but never succeeding.
A time-lapse movie from the Hubble Space Telescope captures the impact of asteroid Dimorphos when it was deliberately hit by NASA's DART spacecraft on Sept. 26, 2022. The movie shows three overlapping stages of the impact aftermath: the formation of an ejecta cone; the spiral swirl of debris caught up along the asteroid's orbit about its companion asteroid; and the tail swept behind the asteroid by the pressure of sunlight. Later on, Hubble records the tail splitting in two.

When the Artemis 1 mission was launched in November, it became the world’s most powerful rocket, and with liftoff came a loud roar heard miles away. In JASA Express Letters, researchers report noise measurements during the launch at different locations around Kennedy Space Center. The data collected can be used to validate existing noise prediction models, which are needed to protect equipment as well as the surrounding environment and community. These data will be useful as more powerful lift vehicles are developed.
Computer software developed at Washington University School of Medicine in St. Louis can predict what happens to complex gene networks when individual genes are missing or dialed up more than usual. Mapping the roles of single genes in these networks is key to understanding healthy development and finding ways to regrow damaged cells and tissues. Likewise, understanding genetic errors could provide insight into birth defects, miscarriage or even cancer.
