Chiropractor says being able to order X-rays is paring redundancy from P.E.I. medical system
Social Sharing After a long wait, chiropractors practising on Prince Edward Island are now able to order X-rays to help them diagnose and treat patients. "This change helps reduce the reliance on primary-care providers and emergency departments to order an X-ray," Health P.E.I. said in a statement to CBC News. "More importantly, it helps to support our Island health care professionals working towards their full scope of practice to enhance access to quality care services for Islanders." Chiropractors had been lobbying the province since at least 2022, seeking to be able to requisition X-rays themselves instead of going through a family doctor. That was impossible in some cases anyway, given that 36,000 people are on the P.E.I. Patient Registry waiting for a primary care provider to be assigned. "It's always been in our scope of practice on Prince Edward Island to be able to order imaging, and it was something that we had hoped wouldn't take as long as it did," said Dr. Chris McCarthy, the chair of the P.E.I. Chiropractic Association. "It's something that we definitely wanted to have happen quicker, but sometimes things can take time." McCarthy said the process would go like this: "We would do up a report, send it off to their primary health-care provider, the patient would then have to book an appointment with that provider, they'd have to wait a bit of time before they could get in, then get the requisition and then get the X-ray done." Patients without a primary care provider would have to use the Maple virtual health-care platform, visit an emergency room, or line up for a walk-in clinic. McCarthy said the change, in effect since April 21, will remove at least one duty from the health-care system's family doctors and nurse practitioners. "It really comes back to just improved health care and patient-centred focus," he said. "It was a bit of a redundancy in the system." He said chiropractors ordering X-rays under the new procedure have been able to identify some injuries already and get the patients the appropriate kind of care. "There was a few fractures that were identified. I know that for sure because I've spoken to a few of the chiropractors that did order those X-rays," he said. "That can make a big difference. If you have a fracture that needs to be addressed, the quicker they can have that addressed the better." Will now lobby for lab access Now for the association's next challenge. "Under the Chiropractic Act, chiropractors in P.E.I. have the scope to diagnose and treat biomechanical disorders, which includes ordering imaging, laboratory, and clinical diagnostic procedures," the Department of Health and Wellness said in a statement to CBC News. But there's something missing, said McCarthy. "We don't have access to labs at the moment. That's something that the association is hoping to move forward, in being able to access some labs," he said.

IN A NUTSHELL 🌌 ASKAP J1832−091 is a mysterious object in the Milky Way, emitting X-rays and radio waves every 44 minutes. is a mysterious object in the Milky Way, emitting X-rays and radio waves every 44 minutes. 🔭 Discovered accidentally, this phenomenon challenges scientists with its synchronized emissions and silent phases. 🧑🔬 Researchers speculate it could be a highly magnetized neutron star or white dwarf, but an entirely new entity is not ruled out. 📡 The discovery underscores the importance of continuous observation and international collaboration in astronomical research. Amidst the vast expanse of our galaxy, a celestial enigma has captured the attention of the scientific community. This mysterious object, discovered by chance, emits X-rays and radio waves at precise intervals of 44 minutes. The origin and nature of this phenomenon remain shrouded in mystery, fueling speculation and fascination among astronomers worldwide. Detected within the heart of the Milky Way, this object has prompted a flurry of research, as experts strive to unravel its secrets and understand its implications for our understanding of the universe. A Celestial Phenomenon in the Heart of the Milky Way Located approximately 9,300 miles from Earth, this celestial object emits synchronized radio signals and X-rays every 44 minutes, a discovery that defies comprehension. A team of international astronomers made this observation using a combination of data from major NASA instruments and ground-based observatories. The Chandra X-ray Observatory, the Spitzer Space Telescope for infrared, and the South African MeerKAT radio telescope played pivotal roles in this groundbreaking discovery. The newly identified object, named ASKAP J1832−091, was detected during a month-long phase of intense activity. During this period, it emitted X-rays and radio waves in a synchronized manner, a behavior never before observed for this type of object. Outside of this hyperactive phase, the object falls into complete silence, with no detectable emissions. Scientists remain uncertain whether it is a dead star, a binary star system, or an entirely new entity. Ziteng Andy Wang, a researcher at Curtin University in Australia and the study's lead author, suggests that the object could be a highly magnetized neutron star or white dwarf. However, he does not rule out the possibility of something radically new. 'Einstein Was Right All Along': This Atomic Clock on the ISS Is Putting General Relativity to Its Ultimate Test A Challenge for Modern Science The discovery of ASKAP J1832−091 was a serendipitous event. Initially, the Chandra telescope was observing the remnants of a supernova when it accidentally picked up the X-ray emissions from this enigmatic object. This marks the first detection of X-rays from a 'long-period radio transient,' a rare class of objects that have puzzled astronomers for years. The exact distance of the object remains uncertain, complicating efforts to determine whether it is related to the observed supernova remnant or if it exists independently in a dense region filled with stars, gas, and dust. For researchers, this discovery opens two major possibilities: they are either witnessing an entirely unknown phenomenon or observing a previously cataloged object from a new perspective. 'Our discovery does not solve the mystery; it deepens it,' admits Wang. This brief period of activity suggests that other similar phenomena might exist but go unnoticed due to a lack of continuous observation. 'They Morph Like Liquid Metal': Scientists Reveal Mini-Robot Swarm That Shape-Shifts Just Like in Sci-Fi Movies Since its launch in 1999, the Chandra telescope has been scrutinizing the universe's most energetic objects. With ASKAP J1832−091, a new chapter unfolds for space research. The study of these mysterious objects could revolutionize our understanding of the universe and its extreme phenomena. Implications for Astronomical Research The unexpected discovery of ASKAP J1832−091 has significant implications for astronomical research. It highlights the importance of continuous observation and the potential for unforeseen phenomena lurking in the cosmos. As astronomers delve deeper into this mystery, they are reminded of the vast unknowns that still exist in our universe.

ASKAP J1832: Scientists discovers mysterious pulsating star in space
Scientists say they've spotted a mysterious object in space behaving in a very strange star, which has been named ASKAP J1832, is acting unlike anything seen before, according to Nasa around 15,000 light years from Earth, it is pulsing every 44 even more strange is that it is doing it with both radio waves and X-rays. What did scientists find? A team of astronomers looked at data from Nasa's space-based Chandra X-ray Observatory and the Square Kilometre Array Pathfinder (ASKAP) radio telescope in Australia to study the discovered object, which has been called ASKAP found that the star belongs to a class of objects called "long period radio transients" - that means it sends out radio waves of different levels over tens of minutes - in this case every 44 they also found that it is also sending X-rays every 44 minutes to Nasa, this combination of factors is "unlike anything astronomers have seen in the Milky Way galaxy."Experts are trying to work out what type of object ASKAP J1832, however they think it might be one of two could be a magnetar - which is a neutron star with an extremely strong magnetic field, with an age of more than half a million it could also be possibly an unusual white dwarf star which has a companion star.

Astronomers discover mysterious star emitting rare combination of X-rays and radio waves
WASHINGTON, May 31 — Astronomers have spotted a star acting unlike any other ever observed as it unleashes a curious combination of radio waves and X-rays, pegging it as an exotic member of a class of celestial objects first identified only three years ago. It is located in the Milky Way galaxy about 15,000 light-years from Earth in the direction of the constellation Scutum, flashing every 44 minutes in both radio waves and X-ray emissions. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). The researchers said it belongs to a class of objects called 'long-period radio transients,' known for bright bursts of radio waves that appear every few minutes to several hours. This is much longer than the rapid pulses in radio waves typically detected from pulsars - a type of speedily rotating neutron star, the dense collapsed core of a massive star after its death. Pulsars appear, as viewed from Earth, to be blinking on and off on timescales of milliseconds to seconds. 'What these objects are and how they generate their unusual signals remain a mystery,' said astronomer Ziteng Wang of Curtin University in Australia, lead author of the study published this week in the journal Nature. In the new study, the researchers used data from Nasa's orbiting Chandra X-ray Observatory, the ASKAP telescope in Australia and other telescopes. While the emission of radio waves from the newly identified object is similar to the approximately 10 other known examples of this class, it is the only one sending out X-rays, according to astrophysicist and study co-author Nanda Rea of the Institute of Space Sciences in Barcelona. The researchers have some hypotheses about the nature of this star. They said it may be a magnetar, a spinning neutron star with an extreme magnetic field, or perhaps a white dwarf, a highly compact stellar ember, with a close and quick orbit around a small companion star in what is called a binary system. 'However, neither of them could explain all observational features we saw,' Wang said. Stars with up to eight times the mass of our sun appear destined to end up as a white dwarf. They eventually burn up all the hydrogen they use as fuel. Gravity then causes them to collapse and blow off their outer layers in a 'red giant' stage, eventually leaving behind a compact core roughly the diameter of Earth — the white dwarf. The observed radio waves potentially could have been generated by the interaction between the white dwarf and the hypothesized companion star, the researchers said. 'The radio brightness of the object varies a lot. We saw no radio emission from the object before November 2023. And in February 2024, we saw it became extremely bright. 'Fewer than 30 objects in the sky have ever reached such brightness in radio waves. Remarkably, at the same time, we also detected X-ray pulses from the object. We can still detect it in radio, but much fainter,' Wang said. Wang said it is thrilling to see a new type of behavior for stars. 'The X-ray detection came from NASA's Chandra space telescope. That part was a lucky break. The telescope was actually pointing at something else, but just happened to catch the source during its 'crazy' bright phase. A coincidence like that is really, really rare - like finding a needle in a haystack,' Wang said. — Reuters
