Today the average person can expect to live nearly twice as long as people in the 1850s. But a new study comparing data from nine human populations and 30 populations of non-human primates says that we are probably not cheating the reaper. The researchers say the increase in human life expectancy is more likely the statistical outcome of improved survival for children and young adults, not slowing the aging clock.
A new study from University of Utah researchers suggests that, due to deforestation and habitat degradation, more bird species may be endangered that previously thought - including species that may not have been discovered yet.
Philosophers, artists and scientists - and probably all the rest of us - have long obsessed over the key to human immortality. We all, no matter our income, culture or religion are bound to die. Even if we escape mortal diseases or accidents, we all face a deadly biological deterioration. While the debate of human longevity has divided the scientific community for centuries, a new study finds fresh evidence for our inevitable death.
Hippopotamus aren't the first thing that come to mind when considering epidemiology and disease ecology. And yet these amphibious megafauna offered UC Santa Barbara ecologist Keenan Stears a window into the progression of an anthrax outbreak that struck Ruaha National Park, Tanzania, in the dry season of 2017.
Rising numbers of liver cancer in Aboriginal and Torres Strait Islander communities has led experts at Flinders University to call for more programs, including mobile liver clinics and ultrasound in rural and remote Australia. The Australian study just published in international Lancet journal EClinicalMedicine reveals the survival difference was largely accounted for by factors other than Indigenous status - including rurality, comorbidity burden and lack of curative therapy.
In 2019, on a small island in coastal South Carolina, biologists discovered an animal migration phenomenon that was difficult to believe. Nearly 20,000 whimbrel were stopping at Deveaux Bank along their migration north -- half the estimated eastern population of the declining shorebird.
A study by University of Rhode Island researchers using a seldom-used methodology turned up many more Eastern spadefoots, an endangered primitive frog, than they expected.
Fewer Atlantic mangrove fiddler crab embryos survived in a warmer, more acid environment mimicking conditions forecast for the end of this century. Given the important ecological role of this invertebrate in mangroves, the researchers warn of a potential cascade effect.
The concentration of potentially toxic metals is increasing in the population of the franciscana dolphin --a small cetacean, endemic from the Rio de la Plata and an endangered species-- according to a study led by a team of the Faculty of Biology and the Biodiversity Research Institute (IRBio), published in the journal Science of The Total Environment.
