Recently, economists and behavioral scientists have studied the pattern of human well-being over the lifespan. In dozens of countries, and for a large range of well-being measures, including happiness and mental health, well-being is high in youth, falls to a nadir in midlife, and rises again in old age. The reasons for this U-shape are still unclear. Present theories emphasize sociological and economic forces. In this study we show that a similar U-shape exists in 508 great apes (two samples of chimpanzees and one sample of orangutans) whose well-being was assessed by raters familiar with the individual apes. This U-shaped pattern or “midlife crisis” emerges with or without use of parametric methods. Our results imply that human well-being’s curved shape is not uniquely human and that, although it may be partly explained by aspects of human life and society, its origins may lie partly in the biology we share with great apes. These findings have implications across scientific and social-scientific disciplines, and may help to identify ways of enhancing human and ape well-being.

The Royal New Zealand Navy is currently awaiting the arrival of its latest Uncrewed Surface Vessel, the wind-powered “Bluebottle,” ahead of a 7-month sea trial.

The Royal New Zealand Navy (RNZN) will soon receive its first 22.3-foot (6.8-meter) long renewable-powered Uncrewed Surface Vessel (USV) to trial on a short-term lease, the New Zealand Defense Force has announced. Called “Bluebottle,” the USV will provide persistent surveillance around the waters of New Zealand for fishery protection, border protection, or meteorological data.

How do forests cool themselves during the summer? This is what a recent study published in Agricultural and Forest Meteorology hopes to find out as a team of international researchers investigated the forests cool themselves through water evaporation and shading. However, climate change could have drastic consequences towards this type of natural air conditioning, specifically from droughts that dry up the soil, disabling a forest’s ability to stay cool during hot months.

For the study, the researchers collected daily measurements over four straight summer seasons of soil moisture and air temperature across 54 sites in broadleaf forests throughout Central Europe. They discovered that shaded forests were typically 2 degrees Celsius (36 degrees Fahrenheit) cooler than temperatures outside the shaded forests. Additionally, they discovered that this cooling effect was driven by soil moisture with this cooling effect becoming less prevalent as soils become drier.

“The findings are alarming in the context of climate change as more frequent and more severe droughts may threaten the cooling functions of forests,” said Dr. Caroline Greiser, who is a landscape ecologist at Stockholm University and lead author of the study.

A recent study published in the Journal of Geophysical Research: Solid Earth sheds new light on the formation of the East Coast of the United States—a “passive margin,” in geologic terms—during the breakup of the supercontinent Pangea and the opening of the Atlantic Ocean around 230 million years ago.

In geology, passive margins are “quiet” areas, locations with minimal faulting or magmatism, where land meets the ocean. Understanding their formation is crucial for many reasons, including that they are stable regions where hydrocarbon resources are extracted and that their sedimentary archive preserves our planet’s climate history as far back as millions of years.

The study, co-authored by scientists from the University of New Mexico, SMU seismologist Maria Beatrice Magnani, and scientists from Northern Arizona University and USC, explores the structure of rocks and the amount of magma-derived rocks along the East Coast and how they change along the margin, which may be tied to how the continent was pulled apart when Pangea fragmented. This event may have also influenced the structure of the Mid-Atlantic Ridge, a vast underwater mountain system running down the center of the Atlantic Ocean.

The goal is to improve the speed, accuracy, and accessibility of weather forecasting and other climate applications.

An earthquake of at least magnitude 7.5 struck Mindanao in the southern Philippines late on Saturday, triggering evacuation orders for some areas of the country and for south-west Japan over warnings of tsunami waves of 1 metre (3ft) or more.

The Philippine Seismology Agency, Phivolcs, said the waves could hit the Philippines by midnight local time (4pm GMT) and continue for hours, though there were no initial reports of significant wave damage by that time.

CHARLESTON, W.Va. (AP) — An entire county school system in coal-producing West Virginia is going solar, representing what a developer and U.S. Sen. Joe Manchin’s office touted on Wednesday as the biggest-ever single demonstration of sun-powered renewable electricity in Appalachian public schools.

The agreement between Wayne County Schools and West Virginian solar installer and developer Solar Holler builds on historic investments in coal communities made possible by the Inflation Reduction Act, which Democratic Sen. Manchin had a major role in shaping as chairman of the Senate Energy and Natural Resources Committee.

Manchin, who announced this month that he wouldn’t run for reelection in the deep-red state, citing an increasingly polarized political system, was quick Wednesday to tout U.S. President Joe Biden’s 2022 landmark climate, health and tax law, which placed special emphasis on creating new clean energy jobs.

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it moves.

Scientists have studied and tracked the motion of the magnetic poles for centuries. The historical movement of these poles indicates a change in the global geometry of the Earth’s magnetic field. It may even indicate the beginning of a field reversal—a “flip” between the north and south magnetic poles.

To address the long-standing debate about whether a massive asteroid impact or volcanic activity caused the extinction of dinosaurs and numerous other species 66 million years ago, a team at Dartmouth College took an innovative approach — they removed scientists from the debate and let the computers decide.

The researchers report in the journal Science a new modeling method powered by interconnected processors that can work through reams of geological and climate data without human input. They tasked nearly 130 processors with analyzing the fossil record in reverse to pinpoint the events and conditions that led to the Cretaceous –Paleogene (K–Pg) extinction event that cleared the way for the ascendance of mammals, including the primates that would lead to early humans.
