Emma Maria Mazzenga of Italy holds four world records in running for the 90-plus age group. Researchers who examined her muscles and bones were surprised to discover extraordinary data that positions her as a living example of healthy aging. Now they’re trying to understand the secret behind her lifestyle. “We have many more experiments to understand the full picture,” they …

A new study reports that women with Alzheimer’s have fewer unsaturated lipids and more saturated ones in their blood. The same pattern did not show up in men with the disease. Almost two thirds of Americans living with Alzheimer’s are women. That gap has puzzled researchers for years. Lipids and Alzheimer’s disease Dr. Cristina Legido-Quigley of King’s College …

Three scientists who revolutionized the treatment of cystic fibrosis and prolonged the lifespan of patients with the deadly disease have won the Lasker Award, one of the most prestigious awards in medicine. Boston-based Vertex Pharmaceuticals researcher Paul Negulescu, former Vertex researcher Jesús (Tito) González, and University of Iowa professor Michael Welsh, will share the $250,000 prize. The Lasker DeBakey Clinical …

For decades, medical science and people believed that Parkinson’s disease originated in the brain, primarily affecting motor function in the body due to loss of dopamine-producing neurons. However, now that science and research are continually advancing, it is challenging the idea that the starting point can likely be: “The gut.”In a landmark study published in NPJ Parkinson’s disease, scientists conducted …

Researchers have finally identified genetic traces of the plague bacterium at the heart of the Byzantine Empire, providing long-sought proof of the microbe behind history’s first pandemic. Credit: Stock USF and FAU researchers identify bacterium behind 1,500-year-old pandemic mystery. For the first time, scientists have obtained direct genomic evidence of the bacterium responsible for the Plague of Justinian, the earliest …

While some humans find they have two left feet on the dancefloor, octopuses manage to coordinate eight highly flexible arms across a host of behaviours, from foraging to den-building, or moving around the seafloor. Now researchers say they have completed the most comprehensive study of its kind, not only identifying the actions and small motions involved in different types of …

Researchers have developed a breakthrough technology that solves a fundamental limit in electronics. This new technology, dubbed an “optoexcitonic switch,” could lead to a new class of electronics — ranging from phones and PCs to data centers and quantum computers that can operate at without generating waste heat. The new switch works like a conventional electronic switch, which uses an …

A potentially huge discovery by NASA’s Perseverance Mars rover will likely remain in scientific limbo for years to come. On Wednesday (Sept. 10), the Perseverance team announced it found possible biosignatures in pieces of a Mars rock called “Cheyava Falls” that the rover first studied last year. Those intriguing chemical fingerprints include the iron-containing minerals vivianite and greigite, which Perseverance …

1I/’Oumuamua, the first interstellar object to visit our solar system in 2017, belongs to a completely new class of space objects, scientists have discovered. It is a piece of an icy exoplanet, more specifically an “exo-Pluto,” a group of cosmic bodies that are highly unlikely to visit the Sun. “Everything about this object is consistent with it being a slab …

Neuroscientists from around the world have worked in parallel to map, for the first time, the entire brain activity of mice while they were making decisions. This achievement involved using electrodes inserted inside the brain to simultaneously record the activity of more than half a million neurons distributed across 95 percent of the rodents’ brain volume. Thanks to the image …
