Introduction to medical artificial intelligence

A lot of us are wondering how our fields could possibly be impacted by this societal shift.Artificial intelligence in medicine and healthcare has been a particularly hot topic in the past few years. Even though there is a sense of great potential from the use of AI in medicine, in addition, there are concerns around […]

We may have misunderstood the beautiful evolution

The opinion nowadays is that ornaments such as the peacock’s magnificent train, the splendid plumes of birds of heaven, bowerbirds’ love nests, deer antlers, fins on guppies and virtually what to do with the mandarin goby are signs of male quality.In such species, females choose males with characteristics that indicate resistance to parasites (shapes go […]

Study: Intense Iridescence Confuses Bumblebees

Although using flashy colors as camouflage may seem counterintuitive, iridescence obstructs the bumblebee’s ability to identify shape, according to a new study published in the journal Scientific Reports. This is a bumblebee landing on an iridescent target. Image credit: Karin Kjernsmo. Iridescence is a taxonomically widespread and striking form of animal coloration which uses regular […]

Panoz-Brown et al show that rats remember a stream of multiple episodes and the order in which they occur by engaging hippocampal-dependent episodic memory replay; rats remember the order of events using episodic memory replay and that replay is part of long-term memory, resistant to interference, and hippocampal dependent. The discovery could help advance the development of new drugs to treat Alzheimer’s disease. Image credit: Panoz-Brown et al, doi: 10.1016/j.cub.2018.04.006.

Non-Human Animals Can Mentally Replay Past Events: Study

A team of Indiana University researchers has reported the first evidence that non-human animals (rats) can replay a stream of multiple episodic memories. The study was published in the journal Current Biology. Panoz-Brown et al show that rats remember a stream of multiple episodes and the order in which they occur by engaging hippocampal-dependent episodic […]

Swamp Sparrows Have Time-Honored Song Traditions, Study Shows

By faithfully copying the most popular songs, swamp sparrows (Melospiza georgiana) create time-honored song traditions that can be just as long-lasting as human traditions, according to a new study, published in the journal Nature Communications. In fact, song traditions in swamp sparrows often last hundreds of years, with some songs going back further than that. […]

Justine et al report new findings obtained mainly by citizen science in metropolitan France and overseas French territories in the Caribbean (Guadeloupe, Martinique, and Saint Barthélemy), South America (French Guiana), and Indian Ocean (La Réunion, Mayotte). Image credit: Jean-Lou Justine.

Giant Hammerhead Flatworms Invade France and Its Overseas Territories

An international team of researchers led by Dr. Jean-Lou Justine of the Muséum National d’Histoire Naturelle, Paris, has identified at least five species of invasive hammerhead flatworms living in metropolitan France, a few European countries, and overseas French territories in three continents. Justine et al report new findings obtained mainly by citizen science in metropolitan […]

Study: Beavers Could Help Curb Soil Erosion, Clean Up Polluted Rivers

A new study, undertaken by a team of University of Exeter researchers using captive Eurasian beavers (Castor fiber), has demonstrated the significant impact the animals have had on reducing the flow of tons of soil and nutrients from nearby fields into a local river system.
