New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest potential can be achieved by protecting existing forests and allowing them to regrow to maturity. Thirty-nine percent can be achieved by reconnecting fragmented landscapes through community-driven ecosystem restoration and management. A natural diversity of species is needed to maximize the forest carbon potential.

From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now, researchers have brought solar panel technology indoors to power smart devices. They show which photovoltaic (PV) systems work best under cool white LEDs, a common type of indoor lighting.

The boom in phones, laptops and other personal devices over the last few decades has been made possible by the lithium-ion (Li-ion) battery, but as climate change demands more powerful batteries for electric vehicles and grid-scale renewable storage, lithium-ion technology might not be enough. Lithium-metal batteries (LMBs) have theoretical capacities an order of magnitude greater than lithium-ion, but a more literal boom has stymied research for decades.

A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.

Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken. Other threats to UK forests include competition with society for water, viral diseases, and extreme weather affecting forest management.

Research has led to the discovery of the role played by the Asian malaria mosquito (Anopheles stephensi) in the spread of drug and diagnosis-resistant malaria in Africa. Malaria is caused by a parasite which is spread by the bite of blood-sucking mosquitoes. According to the WHO, there were an estimated 247 million cases of malaria worldwide in 2021 with over 600,000 deaths, mostly in Africa.  Children under 5 accounted for about 80% of all malaria deaths in the region.

Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.

Researchers have discovered several factors that affect field mouse behavior using seeds from dwarf bamboo plants, a plant that flowers once in a century. Their findings not only suggest the previously underappreciated role of mice in the forest ecosystem, but also show that they store small sasa seeds for later use. These challenge a previously held model of mouse behavior.

An international team of marine scientists has identified and officially named four species of algae new to science, challenging previous taxonomical assumptions within the Porolithon genus. The discovery has far-reaching implications for our understanding of the ecological role of these algae in the coral reef ecosystem.

One of the largest studies to date finds the current generation of EV owners drive far fewer miles than owners of gas vehicles, translating to lower emissions savings from EVs.

Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.

Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.
