Edelman, the world’s largest public relations company, was among the Charles Koch Foundation’s highest-paid vendors in 2022, a 990 tax disclosure form shows, alarming climate advocates.

The PR giant has made numerous climate declarations over the past decade, including making a pledge to eschew projects promoting climate denial. Partnering with a part of the Koch network, which has long worked to sow climate doubt, calls those pledges into question, said Duncan Meisel, the executive director of Clean Creatives, a non-profit pushing creative agencies to cut ties with fossil fuel polluters.

The continents we live on today are moving, and over hundreds of millions of years they get pulled apart and smashed together again. Occasionally, this tectonic plate-fueled process brings most of the world's landmasses together to form a massive supercontinent.

There's no strict definition for a supercontinent, but researchers like Joseph Meert, a professor of geosciences at the University of Florida, say they should include around 75% of the available landmass.

Scientists are still debating how many supercontinents have existed in Earth's history, but they're sure of at least three. Here are all of the known supercontinents that have existed and a few honorable mentions. Live Science spoke with Meert, to check the dates of the supercontinents on this list, but keep in mind they're still only estimates.

When people think about children outside their family and close friends, they commonly make basic needs the priorities. Food, shelter and services such as health and education come first.

When we think of children we have a close relationship with, it's different. We see all their needs as important, immediate and interconnected.

People give as much priority to the higher-order needs as the basic needs of children they're close to.

This thinking carries over into policymaking and intervention priorities in low and middle-income countries. As a result, many interventions in the lives of other people's children, such as responses to a refugee crisis and alternative care for children, put basic needs first.

Our research in the fields of sociology and development economics suggests that children's needs are not hierarchical and that they are best met by—and in—families. By drawing on examples from the literature, we outline how children's various needs are equally important. Caring for them is therefore a balancing act, best done by those close to them: their families.

Insects and spiders often receive little attention from people, except when we're swatting them away. However, as arthropods—creatures distinguished by a hard exoskeleton and jointed legs— they play an essential role in sustaining the ecosystems humans rely on. Remarkably, arthropods make up approximately 84% of all known animal species.

A study published recently in Scientific Reports reveals how human activity affects biodiversity among arthropods and how nonbiological factors, such as daily temperature swings and proximity to the ocean, affect arthropod biodiversity in urban areas.

Innovation may be what drives progress in the arts, business, sciences and technology, but the novel ideas that drive innovation often face headwinds that hinder or even prevent their adoption.

Why did some good ideas, such as hand sanitizing in 19th-century hospitals or racial integration in the 20th century, take years to win widespread embrace? University of Utah postdoctoral researcher Wayne Johnson set out to identify the hurdles.

His research team's program of five studies, which featured analyses of evaluations of films screened at Utah's Sundance Film Festival and of products pitched on the television program Shark Tank, found that people are more likely to disagree about how valuable something is the less familiar it is. That is, the more unconventional a film or company, the wider the range of opinions it will garner.

Record heat, record emissions, record fossil fuel consumption. One month out from Cop28, the world is further than ever from reaching its collective climate goals. At the root of all these problems, according to recent research, is the human “behavioural crisis”, a term coined by an interdisciplinary team of scientists.

“We’ve socially engineered ourselves the way we geoengineered the planet,” says Joseph Merz, lead author of a new paper which proposes that climate breakdown is a symptom of ecological overshoot, which in turn is caused by the deliberate exploitation of human behaviour.
