In a breakthrough that could lead to a simple and inexpensive test for Ebola virus disease, researchers have generated two antibodies to the deadly virus. The antibodies, which are inexpensive to produce, potentially could be used in a simple filter paper test to detect Ebola virus and the related Marburg virus. […]

Researchers can now see how the two sides of the living brain mirror each other thanks to a new combination-imaging technique. The method dubbed 'opto-OISI' takes advantage of rapidly developing high-resolution optical technologies to help make sense of the trillions of connections in the brain. […]

Paleontologists have discovered a new species of meat-eating mammal larger than any big cat stalking the world today. Larger than a polar bear, with a skull as large as that of a rhinoceros and enormous piercing canine teeth, this massive carnivore would have been an intimidating part of the eastern African ecosystems occupied by early apes and monkeys. […]

Researchers report combining cannabinoids with morphine did not significantly increase impulsivity or memory impairment in a study conducted in rhesus monkeys. The findings suggest using opioids and marijuana together could offer a safe way to cut opioid dosage among patients suffering from pain and thereby reduce their risk of becoming addicted to opioids. […]

A research team has determined how several antibodies induced by Epstein-Barr virus (EBV), a herpesvirus that causes infectious mononucleosis and is associated with certain cancers, block infection of cells grown in the laboratory. They then used this information to develop novel vaccine candidates that, in animals, elicited potent anti-EBV antibody responses that blocked infection of cell types involved in EBV-associated cancers. […]

A team of researchers with the University of Neuchâtel in Switzerland and the University of St Andrews in the U.K., has found evidence of titi monkeys using probabilistic predator calls to alert others in their group to the presence of different kinds of danger. In their paper published in the journal Science Advances, the group describes their study of several groups of titi monkeys in the wild and what they found. […]

Baboons are large, smart, ground-dwelling monkeys. They are found across sub-Saharan Africa in various habitats and eat a flexible diet including meat, eggs, and plants. And they are known opportunists – in addition to raiding crops and garbage, some even mug tourists for their possessions, especially food. […]

Researchers have used fossilized teeth found near Lake Turkana in northwest Kenya to identify a new monkey species—a discovery that helps fill a 6-million-year gap in primate evolution. […]

Several meters long and weighing hundreds of kilograms, the Amazon's pirarucu was almost fished to extinction. But the creation of sustainable development reserves in Brazil has ensured the giant fish—and its indigenous hunters—are flourishing again. […]

Scientists are deploying ultra-sensitive sensors in the Amazon to collect images and sounds of the rainforest's rich biodiversity in real time, in an effort to track preservation efforts. […]
