This asynchronous beating comes from how the flight muscles interact with the physics of the insect’s springy exoskeleton. This decoupling of neural commands and muscle contractions is common in only four distinct insect groups. For years, scientists assumed these four groups evolved these ultrafast wingbeats separately, but research from the Georgia Institute of Technology and the University of California, San Diego (UC San Diego) shows that they evolved from a single common ancestor. This discovery demonstrates evolution has repeatedly turned on and off this particular mode of flight. The researchers developed physics models and robotics to test how these transitions could occur.
For the first time, big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to nonbreeding grounds, and back north again during spring migration.
Commercial whaling in the 20th century decimated populations of large whales but also appears to have had a lasting impact on the genetic diversity of today’s surviving whales, new research from Oregon State University shows.

In a new study led by the laboratories of Prof. Prashant Sharma of the University of Wisconsin-Madison, and Dr. Efrat Gavish-Regev of the Hebrew University of Jerusalem, a team of researchers has uncovering the mysteries surrounding camel spiders (Solifugae), by successfully establishing the first-ever comprehensive molecular tree (phylogeny) of this enigmatic arachnid order.
The passenger pigeon. The Tasmanian tiger. The Baiji, or Yangtze river dolphin. These rank among the best-known recent victims of what many scientists have declared the sixth mass extinction, as human actions are wiping out vertebrate animal species hundreds of times faster than they would otherwise disappear.
Remembering the order of information is central for a person when participating in conversations, planning everyday life, or undergoing an education.

A group of researchers have redescribed a unique fossil animal from rocks nearly 520 million years old that fills in a gap in our understanding of the evolution of animals known as arthropods.
Parents with children in adolescence know this all too well: one minute "the little ones" are just up to your shoulder, and all of a sudden, they're growing over your head.
New research from Michigan State University suggests that natural selection, famous for rewarding advantageous differences in organisms, can also preserve similarities.
A new study led by Archaeologist Michelle Bebber, Ph.D., an assistant professor in Kent State University’s Department of Anthropology, has demonstrated that the atlatl (i.e. spear thrower) functions as an “equalizer”, a finding which supports women’s potential active role as prehistoric hunters.
The discovery that birds evolved from small carnivorous dinosaurs of the Late Jurassic was made possible by recently discovered fossils of theropods such as Tyrannosaurus rex and the smaller velociraptors. In a way, you could say that dinosaurs are still with us and seen tweeting from your own backyard! Below are the latest research headlines in the Birds channel on Newswise.
Scientists in South America and Australia have discovered that environmental stresses, such as large variations in rainfall and floods in the rivers, tend to change the mating rituals of these semi-aquatic Neotropical spiders which live in riparian habitats in Uruguay and Brazil.

New research shows that the hormone testosterone — which naturally triggers male electric fish to elongate the electric pulses they send out during the breeding season — also alters a system in the fish’s brain that enables the fish to ignore its own electric signals.
An analysis of the hierarchy of tipping points suggests that during the last 66 million years two events set the scene for further climate tipping and for the evolution of the climate system in particular.
A new DNA study has nuanced the picture of how different groups intermingled during the European Stone Age, but also how certain groups of people were actually isolated.
The Persian Gold Tarantula (Chaetopelma persianum) is a newly described species recently discovered in northwestern Iran. In fact, the “woolly, golden hairs” the scientists observed and examined on a single specimen, were one of the features so unique that it was not necessary for additional individuals to be collected and physically studied.
