Warren Higgs has suffered multiple strokes and aneurysms due to his condition, he told CNN. According to a GoFundMe website, he suffered a severe stroke 15 years ago due to PKD. This incident was followed by six more blows. “It’s awful, it’s a nasty, nasty disease,” he said, adding that his kidneys were already so big that he couldn’t breathe …

Astronomers may have solved the mystery of Betelgeuse’s strange decline in brightness. In the fall of 2019 Betelgeuse – one of the brightest and most famous stars in the sky – began to darken dramatically. By February 2020, it had lost about two-thirds of its normal luminosity. Betelgeuse, which forms the shoulder of constellation Orion (The Hunter) is an inflated …

Findings can have important implications for understanding age-related diseases. Scientists at Sanford Burnham Prebys have gained a deeper understanding of the intricacies of autophagy, the process by which cells break down and recycle cellular components. The findings published in Current biology, describe how the ‘garbage bags’ in a cage – called autophagosomes – are marked to direct their movement to …

A mystery surrounding a galaxy seemingly devoid of dark matter has just deepened after new discoveries from the Hubble Space Telescope confirmed that the galaxy is likely largely free of dark matter, NASA said on Thursday. Dark matter is estimated at about 85% of all matter in the universe, so scientists were surprised when they discovered a galaxy in 2018, …

After facing “technical delays” during a spacewalk on Wednesday, NASA astronaut Shane Kimbro and European Space Agency astronaut Thomas Peske are conducting a second spacewalk on Sunday to continue installing new solar grids. The panels will help provide power amplification to the space station. Sunday space was already on schedule. The astronauts will simply move some of the work on …

From lunar eclipse to partial solar eclipse to supermoon, 2021 is a spectacular year for lunar events. But this month marks the final supermoon of the year, with the full “strawberry” moon illuminating the night sky next week. A supermoon occurs when the Moon is at its closest point to Earth in its orbit, known as the perigee. It looks …

About 25 million years ago, giant rhinos more than 16 feet tall roamed the Earth. They are considered to be the largest terrestrial mammal that ever lived, but their evolutionary history and scattering in Asia leave scientists confused. Paleontologists have now found fossils of a new, sixth species of the extinct giant rhinoceros, Paraceratherium linxiaense, which shed light on how …

As we gain a greater ability to peer deeper and deeper into the universe, we discovered something very surprising: supermassive black holes millions to billions of times the mass of the Sun before the universe was even 10 percent of its current age. This is quite a cosmological mystery. Given what we know about the growth rate of black holes, …
