Safeguarding children in childcare: Teacher confidence key to addressing trauma‎

To better understand how young children experiencing trauma are supported in early learning settings, Adelaide University researchers examined the role of teacher self-efficacy—the confidence teachers have in their knowledge and abilities—in creating safe, responsive learning environments.

Male coyote swam 2 miles to Alcatraz Island, twice as far as biologists had expected‎

A lone coyote stunned biologists and others when it paddled its way to remote Alcatraz Island earlier this year, a former federal prison in the San Francisco Bay surrounded by swift, choppy waters notorious for thwarting prisoners' escapes.

CPR simulator for space use tracks the differences of blood flow in reduced gravity‎

The new focus on manned missions to the moon and Mars presents countless pressing challenges, including keeping humans alive in hostile environments. What happens when an astronaut or space tourist has a cardiac emergency millions of miles from the nearest hospital?

Polymer 'bristles' could help repel proteins—and germs—from surfaces in medical settings‎

A non-toxic coating developed by researchers at University of Toronto Engineering prevents proteins from sticking to surfaces—potentially offering a new tool in the fight against hospital-acquired infections.

Colonialism and the role of science in the history of Lake Malawi's fisheries‎

Many scholars have studied the effects of colonial management on terrestrial resources, but what about the effect of colonialism on bodies of water? A new article in Isis: A Journal of the History of Science Society examines the ways in which fisheries science and colonial development converged for the purpose of exploiting marine resources in British-controlled Nyasaland (now Malawi).

Carnivorous plants and wasps blur the line between friend and food‎

Acid-filled pitchers complete with fangs. Labyrinthine chambers decorated with bristles. Leaves that snap shut in less than a second. Employing strategies like these, carnivorous plants have a reputation as fearsome predators, but a new study published in the journal Ecology suggests they may do more to help their insect neighbors than previously thought.

A skull full of surprises: Discovering the evolutionary secrets of fish brains‎

A new study in Proceedings of the Royal Society B reveals the surprising neurological landscape of fish brains. Harvard researchers map the internal structures of ray-finned fishes' brains in 3D detail, discovering brain size and shape, as well as the endocasts, vary far more than expected.

Climate scientist finds large errors in a global climate pollution database‎

New research from Northern Arizona University found that a global greenhouse gas emissions database produced by the Climate TRACE consortium, co-founded by former Vice President Al Gore, is underestimating vehicle carbon dioxide emissions in cities by an average of 70%.

The moon's formation still remains a mystery in many ways‎

A half century after NASA's Apollo 17 lunar module lifted off the moon's northeastern near side quadrant, planetary scientists still don't completely understand when or how our moon first formed. They do agree that it involved a major impactor—an object dubbed Theia by lunar scientists—that likely struck Earth some 4.51 billion years ago. But the estimated size of Theia now ranges from a proto-Mercury-sized object all the way up to an object that was about half the size of present-day Earth.
