A newly developed technique that shows artery-clogging fat-and-protein complexes in live fish gave investigators from Carnegie, Johns Hopkins University, and the Mayo Clinic a glimpse of how to study heart disease in action. Their research, which is currently being used to find new drugs to fight cardiovascular disease, is now published in Nature Communications.
A study published in the journal Vision Research helps explain how animals the size of a bread crumb fit all the complex architecture of adult eyes into a much tinier package.
A hormone that is released in our brain when we fall in love also makes starfish turn their stomach inside out to feed, according to a new study from the Queen Mary University of London.
Imagine your favorite beach filled with thousands of ducks and gulls. Now envision coming back a week later and finding condos being constructed on that spot. This many ducks in one place surely should indicate this spot is exceptionally good for birds and must be protected from development, right?
The human ranging style is unique among hominoids. The Mbendjele BaYaka people move from camp to camp every few months and thus have a large lifetime range of approximately 800 square meters. Human foragers collect food and take it back to their camp to process and share.
The global price of ivory increased tenfold since its 1989 trade ban by the Convention on the International Trade in Endangered Species (CITES), new research has found. The University of Bristol Veterinary School study, published in Biological Conservation [25 July], is the first to analyze trends in global ivory market values since the ban came into effect.
A new study on a Bahamian bat makes the case for using the species' unusual parasites to reveal details about the species' populations on the archipelago. Using parasites to glean information about their hosts isn't a new concept, but typically scientists have focused only on parasites that exhibit tight links with individual hosts in a species over tens of thousands of years.
In pre-Columbian times, the white-tailed deer was among the most abundant and frequently consumed mammals in Panama.
Tourists on safari can provide wildlife monitoring data comparable to traditional surveying methods, suggests research appearing July 22 in the journal Current Biology. The researchers analyzed 25,000 photographs from 26 tour groups to survey the population densities of five top predators (lions, leopards, cheetahs, spotted hyenas, and wild dogs) in northern Botswana, making it one of the first studies to use tourist photographic data for this purpose.
Scientists have found that mosquitoes are changing their hunting routines in response to host cues. For example, in Africa, mosquitoes now recognize when people emerge from bednets in the morning and have begun hunting more often during the day than at night.
Described in 1981, the genus Biswamoyopterus is regarded as the most mysterious and rarest amongst all flying squirrels. It comprises two large (1.4-1.8 kg) species endemic to southern Asia: the Namdapha flying squirrel (India) and the Laotian giant flying squirrel (Lao PDR). Each is only known from a single specimen discovered in 1981 and 2013, respectively.
Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these "micro-bristle-bots" might work together to sense environmental changes, move materials - or perhaps one day repair injuries inside the human body.
The culprit responsible for the decline of Mexico's once-lucrative jumbo squid fishery has remained a mystery, until now. A new Stanford-led study published in the ICES Journal of Marine Science identifies shifting weather patterns and ocean conditions as among the reasons for the collapse, which spells trouble for the Gulf of California's marine ecosystems and fishery-dependent economies. It could also be a sign of things to come elsewhere.
A total of 55 animal species in the UK have been displaced from their natural ranges or enabled to arrive for the first time on UK shores because of climate change over the last 10 years (2008-2018) - as revealed in a new study published today (18 July 2019) by scientists at international conservation charity ZSL (Zoological Society of London).
In the 1960s, Penn biologist Dan Janzen, as part of earning his Ph.D., re-described what has become a classic example of biological mutualism: the obligate relationship between acacia-ants and ant-acacia trees. The acacia trees produce specialized structures to shelter and feed the ant colony, and the ants, in turn, defend the tree against herbivores.
