Newly discovered genetic switches that increase lifespan and boost fitness in worms are also linked to increased lifespan in mammals, offering hope that drugs to flip these switches could improve human metabolic function and increase longevity.
One of the Earth's newest islands exploded into view from the bottom of the southwest Pacific Ocean in January 2015, and scientists sailing around the volcano this spring have created a detailed map of its topography.
The Nazca Lines were carved into the ground centuries ago, and their significance remain an enigma today. They’re also still being found. A new geoglyph about 30 meters long was found at Pampa de Majuelos.
Not even the surest surgeon’s hand is quite as steady and consistent as a robotic arm built of metal and plastic, programmed to perform the same motions over and over. So could it handle the slippery stuff of soft tissues during a surgery?
Investigators from NewYork-Presbyterian and Weill Cornell Medicine question the results of a large-scale clinical trial assessing the value of PSA screening, which served as the basis for the U.S. Preventative Services Task Force's 2012 recommendations against routine prostate cancer screening.
Laboratory Equipment's scientist of the week is Hongrui Jiang, of the University of Wisconsin, Madison. Jiang combined the best features of a lobster and an African fish to create an artificial eye that can see in the dark.
Waves of dead sea creatures, including whales, salmon and sardines, have washed up on the shores of Chilean beaches in recent months - and the weather caused by El Niño may be to blame.
Planet Nine, a far-off body astronomers have not yet even seen, remains a mystery. Was it a planet that was pulled far out of the center of the solar system? Could it have been ejected to the outer reaches of orbit by Jupiter and Saturn, the major gas giants?
It’s time for your primary care check-up, and the doctor asks you to list any known drug allergies. “Penicillin,” you say immediately, although you can’t remember actually taking the drug or having a reaction to it.
Polyurethanes in products from cushy sofas to stretchy spandex have made sitting, sleeping and walking more comfortable. But once they have served their purpose, most of the non-degradable materials pile up in landfills.
An international team of scientists uncovered the first molecular evidence indicating that dung beetles evolved in association with dinosaurs. The findings challenge previous research that associates the origin of dung feeding with mammals.
It’s known as the cocktail-party problem: in the cacophony of sound made by insects in a spring meadow, how does one species recognize its own song?
Loyola University Chicago researchers are among the co-authors of a groundbreaking study that found humans have a higher metabolism rate than closely related primates, which enabled humans to evolve larger brains.
Scientists have grown and catalogued more than 130 bacteria from the human intestine. The researchers have developed a process to grow the majority of bacteria from the gut, which will enable them to understand how our bacterial 'microbiome' keeps us healthy.
Analyzing medical death rate data over an eight-year period, Johns Hopkins patient safety experts have calculated that more than 250,000 deaths per year are due to medical error in the U.S.
