For decades, the story of Alzheimer’s research has been dominated by a battle between A-beta and tau amyloids, both of which can kill neurons and impact the brain’s ability to function. A new study suggests, however, that these sticky brain plaques may not be operating alone. Johns Hopkins University researchers have identified more than 200…
Pepper, the pet cat who made headlines last year for his role in the discovery of the first jeilongvirus found in the U.S., is at it again. This time, his hunting prowess contributed to the identification of a new strain of orthoreovirus. John Lednicky, Ph.D., Pepper’s owner and a University of Florida College of Public…
An artistic rendering based on a real image of the IceCube neutrino detector at the South Pole IceCube/NSF We are zeroing in on the true composition of the rarest, highest-energy cosmic rays – which could help reveal their unknown origins. The universe is constantly showering us with bursts of particles, says Brian Clark at the…
A mystery interstellar object spotted last week by astronomers could be the oldest comet ever seen, according to scientists. Named 3I/Atlas, it may be three billion years older than our own solar system, suggests the team from Oxford university. The preliminary findings were presented on Friday at the national meeting of the UK’s Royal Astronomical…
It turns out color isn’t just fashionable for guppies: According to a new UBC study, the more orange a male, the more virile it is. The research published in Nature Ecology & Evolution shines light on an enduring evolutionary mystery: why male guppies have such vibrant and varied colors and patterns. Virile me up Zoologists…
In the last year, there has been a surge in proteins developed by AI that will eventually be used in the treatment of everything from snakebites to cancer. What would normally take decades for a scientist to create — a custom-made protein for a particular disease — can now be done in seconds. For the…
The plasma near Jupiter’s poles is capable of unusual behaviour NASA/JPL-Caltech/SwRI/MSSS; Oleksuik © CC NC SA The cosmic neighbourhood of Jupiter is one of the more peculiar places in the solar system, and the plasmas that reside there are no exception. They ripple with a never-before-seen type of wave. Robert Lysak at the University of…
It’s been recognized for some time that Alzheimer’s disease affects brain regions differently and that tau — a protein known to misbehave — plays an important role in the disease. Normally, tau helps stabilize neurons, but in Alzheimer’s disease, it begins to misfold and tangle inside neurons. It spreads across the brain forming toxic clumps…
What can lemurs tell us about inflammation and aging, aka “inflammaging” in humans? That’s the question Elaine Guevara, a biological anthropologist who studies the evolution of life history and aging in primates, set out to understand. In newly published research on age-related inflammation in ring-tailed and sifaka lemurs, Guevara discovered that perhaps we should rethink…
