African honeyguide birds understand and respond to the culturally distinct signals made by local human honey hunters, suggesting cultural coevolution between species, according to a new study. Although the animal kingdom is full of interspecific mutualism, systems in which humans successfully cooperate with wild animals are rare. One such relationship involves the greater honeyguide (Indicator indicator), a small African bird known to lead humans to wild bees’ nests. Humans open the nests to collect honey, and the honeyguides eat the exposed beeswax. Human honey hunters in different parts of Africa often use ...

The controlled creation of quantum entanglement with molecules has been a long-standing challenge in quantum science. Now, in two new studies, researchers report a method for tailoring the quantum states of individual molecules to achieve quantum entanglement on demand. Their strategy presents a promising new platform for the advancement of quantum technologies such as computation and sensing.

Annual tree-ring growth records from more than 122 species of trees show that trees growing in wetter forests are more sensitive to increasing drought. The findings – which tackle a research question that has yielded contradictory results in the past – suggest that land management and policy focused solely on drought effects in drier regions overestimates the resilience of forests in wetter regions. Forests cover roughly 30% of Earth’s surface and, in addition to providing a host of valuable ecosystem services and harboring huge biodiversity, they play a crucial role in the planet’s carbon cycle, absorbing more atmospheric carbon than all other terrestrial ...

A massive new review of ancient atmospheric carbon-dioxide levels and corresponding temperatures lays out a daunting picture of where the Earth’s climate may be headed. The study covers geologic records spanning the past 66 million years, putting present-day concentrations into context with deep time. Among other things, it indicates that the last time atmospheric carbon dioxide consistently reached today’s human-driven levels was 14 million years ago—much longer ago than some existing assessments indicate. It asserts that long-term climate is highly sensitive to greenhouse gas, with cascading effects that may evolve over many millennia. The ...

In many parts of Africa, humans cooperate with a species of wax-eating bird called the greater honeyguide, Indicator indicator, which leads them to wild bees’ nests with a chattering call. By using specialised sounds to communicate with each other, both species can significantly increase their chances of accessing calorie-dense honey and beeswax. Human honey-hunters in different parts of Africa use different calls to communicate with honeyguides. In a new study, researchers have discovered that honeyguide birds in Tanzania and Mozambique discriminate among honey-hunters’ calls, responding much more readily to ...

 Embargoed: Not for Release Until 2:00 pm U.S. Eastern Time Thursday, Dec. 7 2023. Today atmospheric carbon dioxide is at its highest level in at least several million years thanks to widespread combustion of fossil fuels by humans over the past couple centuries. But where does 419 parts per million (ppm)—the current concentration of the greenhouse gas in the atmosphere—fit in Earth’s history? That’s a question an international community of scientists, featuring key contributions by University of Utah geologists, is sorting out by examining a plethora of markers in the geologic record that offer ...

How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of element formation in stars. We are, literally, made of star stuff. Stars are element factories, where elements constantly fuse or break apart to create other lighter or heavier elements. When we refer to light or heavy elements, we’re talking about their atomic mass. Broadly speaking, atomic ...
