Earth system box models are essential tools for reconstructing long-term climatic and environmental evolution and uncovering Earth system mechanisms. To overcome the spatiotemporal resolution limitations of current deep-time models, a research team has developed CESM-SCION, a new-generation high-resolution climate-biogeochemistry coupled model. This model advances the spatiotemporal resolution of long-term Earth system simulations to a new level and identifies marine regression as a key driver of the Late Paleozoic Ice Age onset.

A new study from Bar-Ilan University shows that one of sleep's core functions originated hundreds of millions of years ago in jellyfish and sea anemones, among the earliest creatures with nervous systems. By tracing this mechanism back to these ancient animals, the research demonstrates that protecting neurons from DNA damage and cellular stress is a basic, ancient function of sleep that began long before complex brains evolved.

The Atlantic Meridional Overturning Circulation (AMOC) is the system of currents responsible for shuttling warm water northward and colder, denser water to the south. This "conveyor belt" process helps redistribute heat, nutrients, and carbon around the planet.

A collaborative team of researchers from the Donald Danforth Plant Science Center, the University of Florida, Gainesville and University of Iowa have developed tools that allow grasses—including major grain crops like corn—to act as living biosensors capable of detecting minute amounts of chemicals in the field.

The mid-ocean ridge runs through the oceans like a suture. Where Earth's plates move apart, new oceanic crust is continuously formed. This is often accompanied by magmatism and hydrothermal activity. Seawater seeps into the subsurface, is heated to temperatures above 400°C, and rises again to the ocean floor.

For centuries, scientists have known that plants "breathe" through microscopic pores on their leaves called stomata. These tiny valves are the gatekeepers that balance the intake of carbon dioxide into the leaf for photosynthesis against the loss of water vapor from the leaf to the atmosphere.

Yeast left over from brewing beer can be transformed into edible "scaffolds" for cultivated meat—sometimes known as lab-grown meat—which could offer a more sustainable, cost-effective alternative to current methods, according to a new study from UCL (University College London) researchers.

Two new studies into lizard colors reveal how one species maintains its colorful diversity while others are losing their ancient colors. And the changes are being driven by the biological equivalent of rock-paper-scissors.

Triacetic acid lactone (TAL) has the potential to serve as a bioderived platform chemical for commercial products, including sorbic acid. However, TAL currently lacks a global market as its chemical synthesis is prohibitively expensive.

There are "costs of life" that mechanical physics cannot calculate. A clear example is the energy required to keep specific biochemical processes active—such as those that make up photosynthesis, although the examples are countless—while preventing alternative processes from occurring.

In Kosciuszko National Park in Australia's alpine region, the landscape is slowly changing. Patches of native vegetation cropped bald by horses are regrowing. Some long-eroded creek banks look less compacted along the edges. Visitors come across fewer horses standing on the roads, a real traffic hazard.

For decades, EU chemical regulation has struggled with slow approvals, high costs, and ecological surprises. From delayed bans on neonicotinoids to the ongoing decline of pollinators, the current framework often reacts too late. Assessments are fragmented, focusing on individual products rather than the bigger picture. Decisions are locked into binary categories: "safe" or "unsafe"—leaving no room for adaptive management.

When we talk about disasters, we often default to the language of nature. We describe storms as "unprecedented," floods as "once-in-a-century," and heat waves as "record-breaking." While these descriptors may be technically accurate, they miss a more fundamental point: Disasters do not occur in a vacuum. They unfold within environments that humans have designed, built, maintained, and—often—neglected over long periods of time.

Monitoring forest health typically relies on remote sensing tools such as light detection and ranging (LiDAR), radar, and multispectral photography. While radar and LiDAR penetrate canopies to reveal structure, they struggle to provide fine-resolution spectral details needed for vegetation health assessment.

Humans like plants. We like seeing them change the color of their leaves throughout the year. They connect us to nature even if we live in a big city. But most people don't think that much about the lives of plants, and least of all, about their sex life.

Alessandra Moreira worked as an administrative assistant in Altamira, an oversized municipality in the Brazilian Amazon — larger than Portugal or Greece. Burned out and facing anxiety and depression, she left her job, but was unsure of what would come next. “I was having panic attacks and couldn’t identify what was happening to me,” she told Mongabay. Then, a suggestion from her brother changed everything: Why not try making seed paper? Altamira, in the state of Pará, is the most deforested municipality in the Brazilian Amazon. There, “development” is often a synonym for deforestation, environmental degradation, and sometimes violence, erupting from clashes between conservationists, loggers and land grabbers. Despite the local culture, Moreira founded Ecoplante, a company that makes plantable seed paper — recycled sheets embedded with seeds that can typically grow into vegetables, herbs, flowers and, in Ecoplante’s specific case, native Amazonian vegetation, too. What began as a personal healing project has grown into an example of how creativity, entrepreneurship and sustainability can coexist in one of the world’s most fragile ecosystems. Plantable seed paper is made by transforming discarded paper into new sheets infused with plant seeds. The process starts with recycled pulp mixed with water, then spread over a fine-mesh screen and layered with seeds, from herbs like basil and arugula, to flowers like daisies. Once dried, the paper can be written on, used, and later planted. When it decomposes, the seeds germinate, turning what would have been waste into greenery. In 2023, Moreira and her brother…This article was originally published on Mongabay

More than 145,000 African forest elephants roam the rainforests of Africa, according to a recent population assessment. Published in December by the African Elephant Specialist Group at the IUCN, the global wildlife conservation authority, the survey relies on improved DNA-based techniques to provide the first estimate for these critically endangered pachyderms since they were recognized as a distinct species in 2021. African forest elephants (Loxodonta cyclotis) are found primarily in the dense rainforests of Central Africa, with significant but dwindling numbers remaining in West Africa, and small populations in East and Southern Africa. Hybrids with their close cousins, savanna elephants (Loxodonta africana), also occur infrequently where both forest and savanna elephants are found. Counting these shy and elusive giants is a challenge for researchers as they blend into their surroundings or vanish into the dense understory of their forest habitat.

Some 153 population surveys, carried out between 2016 and 2024 across roughly three-quarters of L. cyclotis’s known range, counted 135,690 forest elephants. The IUCN’s assessment included 22 elephant populations, mostly in Central Africa, that had not previously been surveyed. The researchers estimate there are as many as 11,000 more elephants in the remaining parts of the species’ range, pushing the total to just over 145,000 individuals. “This report is the first one that shows forest elephant numbers,” report author Fiona Maisels, a conservation scientist with the Wildlife Conservation Society (WCS), told Mongabay by email. “In previous iterations, the…This article was originally published on Mongabay
