Super-Earth exoplanets often have giant ‘Jupiter’ bodyguards

Planetary systems with both super-Earths and Jupiter-type planets may be common, according to a new study. As in our own solar system, the giant planets would act as “bodyguards” protecting the smaller planets from asteroid impacts.

Bat-winged dinosaurs that could glide

(McGill University) Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, according to a new study led by an international team of researchers, including McGill University Professor Hans Larsson. Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years. The findings, published in iScience, support that dinosaurs evolved flight in several different ways before modern birds evolved.

Comparing canine brains using 3D-endocast modelling

(Eötvös Loránd University (ELTE), Faculty of Science) Based on digital endocranial cast models the canine brain does not increase proportionally with body size. Researchers at ELTE Eötvös Loránd and Kaposvár University in Hungary reconstructed the surface morphology of 28 canine brains, including various dog breeds, wolves, coyotes, and jackals. The shortening of the facial skeleton greatly influences the ratio of certain brain regions, primarily the olfactory bulb and the frontal lobe. These changes might have profound implications for olfactory and problem-solving abilities.

AI detects hidden earthquakes

(Stanford University) Tiny movements in Earth’s outermost layer may provide a Rosetta Stone for deciphering the physics and warning signs of big quakes. New algorithms that work a little like human vision are now detecting these long-hidden microquakes in the growing mountain of seismic data.

Climate ‘Catastrophe’ Myths And Realities—And Why You Should Care

Those of us who reject the idea that mankind controls Earth’s thermostat do so for many reasons. As yet there exists no physical evidence to link the steady growth of carbon dioxide beginning in the 1950s with the erratic atmospheric…

This beetle can survive getting run over by a car. Engineers are figuring out how

Getting run over by a car is not a near-death experience for the diabolical ironclad beetle. How the beetle survives could inspire the development of new materials with the same herculean toughness, engineers show.

Artificial intelligence reveals hundreds of millions of trees in the Sahara

(University of Copenhagen) There are far more trees in the West African Sahara and Sahel than most would expect. A combination of artificial intelligence and detailed satellite imagery allowed a team from the University of Copenhagen and international collaborators to count all trees across a 1.3 million km2 area of West Africa.

Tiny beetles a bellwether of ecological disruption by climate change

New research shows that as species across the world adjust where they live in response to climate change, they will come into competition with other species that could hamper their ability to keep up with the pace of this change.

CRISPR-induced immune diversification in host-virus populations

Just like humans, microbes have equipped themselves with tools to recognize and defend themselves against viral invaders. In a continual evolutionary battle between virus and host, CRISPR-Cas act as a major driving force of strain diversity in host-virus systems.
