Our analysis suggests that while the profits are soft, the foundations of the business are strong. AI is about to change healthcare. These 20 stocks are working on everything from early diagnostics to drug discovery. The best part - they are all under $10bn in marketcap - there is still time to get in early. How Do Unusual Items Influence Profit? For anyone who wants to understand Senior's profit beyond the statutory numbers, it's important to note that during the last twelve months statutory profit was reduced by UK£33m due to unusual items. While deductions due to unusual items are disappointing in the first instance, there is a silver lining. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And that's hardly a surprise given these line items are considered unusual. In the twelve months to June 2025, Senior had a big unusual items expense. All else being equal, this would likely have the effect of making the statutory profit look worse than its underlying earnings power. That might leave you wondering what analysts are forecasting in terms of future profitability. Luckily, you can click here to see an interactive graph depicting future profitability, based on their estimates. Our Take On Senior's Profit Performance As we mentioned previously, the Senior's profit was hampered by unusual items in the last year. Based on this observation, we consider it possible that Senior's statutory profit actually understates its earnings potential! And on top of that, its earnings per share have grown at an extremely impressive rate over the last three years. The goal of this article has been to assess how well we can rely on the statutory earnings to reflect the company's potential, but there is plenty more to consider. If you'd like to know more about Senior as a business, it's important to be aware of any risks it's facing. For example - Senior has 1 warning sign we think you should be aware of. This note has only looked at a single factor that sheds light on the nature of Senior's profit. But there are plenty of other ways to inform your opinion of a company. Some people consider a high return on equity to be a good sign of a quality business. While it might take a little research on your behalf, you may find this free collection of companies boasting high return on equity, or this list of stocks with significant insider holdings to be useful.

Astronomers caught a star that blew up not once, but twice when it died
Astronomers have finally caught a dying star in space going out with a bang — and then another bang. The new photographic evidence, captured using the European Southern Observatory's Very Large Telescope in Chile, shows the first proof of a rare kind of stellar death called a double-detonation supernova. This double-blast event, spotted in the supernova remnant known as SNR 0509-67.5, confirms a theory that has divided astrophysicists for decades. The star's remains, about 300 years old, show a distinctive pattern: two separate shells of calcium, one nested inside the other like Russian matryoshka dolls. This could only form if a white dwarf exploded twice. The breakthrough, published in Nature Astronomy, rewrites part of the story behind one of the most important tools in astronomy, the Type Ia supernova. Sometimes dubbed a "cosmic yardstick" by NASA, this special supernova shines brightly for a short time and gives off a predictable, known amount of light. That makes it perfect for measuring distance in space: The farther the supernova, the fainter it appears to us. By collecting light from these blasts, scientists also can figure out how fast the universe has been expanding. "Our results required a large resource commitment with a very advanced instrument on a large telescope," Ivo Seitenzahl, one of the researchers, told Mashable. "Basically, the observations are near the limit of what's currently technically feasible." Understanding how exactly these events work isn't just academic, it's essential for making sense of the universe. These explosions forge the majority of iron in our galaxy — the same stuff found in our blood, buildings, and planet. A white dwarf star — the dense stellar core left behind after a sun-like star runs out of fuel — gradually steals material from a neighboring star. Once it grows massive enough, it ignites in a thermonuclear explosion. But some researchers have suspected there is another way: A thin outer layer of helium could explode first, sending a shockwave inward that then blows up the white dwarf's core. The second blast is the ultimate supernova that tears the star apart. Until now, this two-step concept lived mostly on whiteboards and in computer simulations. Now, astronomers have receipts proving it really happens. The explosions would have occurred in quick succession, Seitenzahl said. The second blast likely followed just two seconds later, "essentially the time it takes the helium detonation to travel from one side of the white dwarf star to the other." Scientists turned the telescope's Multi Unit Spectroscopic Explorer instrument toward the glowing wreckage in the Large Magellanic Cloud, a galaxy neighboring the Milky Way. The calcium detections were the giveaway. Sandwiched in between the blown-off shells was sulfur, with each layer consisting of different densities from the two explosions. "Revealing the inner workings of such a spectacular cosmic explosion is incredibly rewarding," said Priyam Das, lead author of the paper, in a statement, describing the remnant as a "beautifully layered structure." Astronomers can't normally see what happens deep inside a star during its final moments. The explosion itself is too bright, fast, and distant. But hundreds of years later, the drifting shrapnel betrays the secret. Though this discovery doesn't close the case on how all Type Ia supernovas work, it does show at least some stars don't need to hit a critical mass of matter before going boom. It seems a smaller star with the right kind of helium wrapper can self-destruct just fine. For this particular system, there won't be any more explosions, but the hunt continues for variations on this exotic breed. Some models for double detonations indicate the primary star can actually trigger yet another double detonation in the lighter companion star. "This would be a double double detonation," Seitenzahl said. UPDATE: Jul. 2, 2025, 12:50 PM EDT This story has been updated to include additional reporting, including new quotes, from the researchers.

‘It's very exciting' – first images of double supernova captured by team including Trinity College astronomer
The first visual evidence of a dying star having been ripped apart by a double explosion has been reported by Nature Astronomy. The astronomers viewed what's left of supernova SNR 0509-67.5 – which exploded centuries ago – using the European Southern Observatory's Very Large Telescope in Chile's Atacama Desert. They saw two shells – or layers – of calcium still remained and appear blue in the captured images. The double explosion was predicted, theoretically, by Christine Collins – a Marie Sklodowska-Curie research fellow in the School of Physics at TCD – before it was observed. 'I was involved with the work that made this prediction,' said Dr Collins. 'It's very exciting to be part of this discovery. 'The prediction that these explosions leave behind the distinct calcium shell signature came directly out of the simulations, although we didn't realise at the time that it would be a feature that could be observed in a supernova remnant.' An international team of astronomers from Australia, Germany, Switzerland, the US, Canada and Ireland set out to test the theory that a double detonation was possible in a white dwarf star. This theory proposed that the white dwarf – the core of a dying star left behind after it's used up its nuclear fuel – would gather helium from a companion star, become unstable, then explode. Very strong evidence that this supernova was triggered by a double detonation The shockwaves from that first explosion would then trigger a second detonation of the white dwarf, which would produce a supernova with two circular shells of calcium left as stellar imprints and visual evidence of each explosion. 'This is very strong evidence that this supernova was triggered by a double detonation,' Dr Collins said. Dr Collins had predicted that the existence of at least some type Ia supernovae (SNe Ia) could be best explained by a double detonation. 'It is a very nice case where we had a theoretical prediction and then the signature was identified in observations,' Dr Collins added. The observed confirmation that a white dwarf suffered two explosive blasts is a discovery that sheds new light on stellar explosions. The SNe Ia is a subclass of supernova that results from white dwarfs exploding. They are considered important for a general understanding of the universe because they are predictably bright, no matter how far away they are from us. They help astronomers to measure distances in space. This was how astronomers discovered that the expansion of the universe was accelerating – a finding that was the basis for the Nobel Prize in Physics in 2011. Type Ia supernovae are also viewed as important by astronomers because they are the primary source of iron in the universe – even in human blood. Yet, despite their importance, the puzzle of what exactly caused them remained unsolved, until now.

Astronomers get first visual of a sun dying by detonating twice
In a first-of-its-kind observation, astronomers have obtained the visual evidence of a star dying by double detonation, when stars are known to disappear by giant European Southern Observatory's Very Large Telescope has studied the centuries-old remains of supernova SNR 0509-67.5 to confirm the patterns of dual back-to-back explosions obliterated a white dwarf that had a mass roughly equal to the sun and was located about 1,60,000 lightyears from Earth in the direction of the constellation Dorado in a galaxy near the Milky Way called the Large Magellanic Cloud. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). This image shows the distribution of calcium in the supernova remnant SNR 0509-67.5. (Photo: ESO) advertisement "The explosions of white dwarfs play a crucial role in astronomy. Yet, despite their importance, the long-standing puzzle of the exact mechanism triggering their explosion remains unsolved," Priyam Das, a PhD student at the University of New South Wales Canberra, who led the study, details of the finding were published in the journal Nature Astronomy. Astronomers had long been suspecting that some stars do meet their end of life with a dual detonation and new images prove their hunch was right: at least some Type Ia supernovae explode through a 'double-detonation' mechanism instead."The time delay between the two detonations is essentially set by the time it takes the helium detonation to travel from one pole of the star all the way around to the other. It's only about two seconds," said astrophysicist and study co-author Ivo Seitenzahl, a visiting scientist at the Australian National University in Canberra. This image marks the position on the sky of the supernova remnant SNR 0509-67.5. (Photo: ESO) advertisementIn the more common type of supernova, a remnant of the massive exploded star is left behind in the form of a dense neutron star or a black hole.'This tangible evidence of a double-detonation not only contributes towards solving a long-standing mystery, but also offers a visual spectacle,' Priyam says, describing the 'beautifully layered structure' that a supernova creates. For him, 'revealing the inner workings of such a spectacular cosmic explosion is incredibly rewarding.'- EndsTrending Reel
