Diverse forests hold huge carbon potential, as long as we cut emissions      (via sciencedaily.com)     Original source 

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.

'Indoor solar' to power the Internet of Things      (via sciencedaily.com)     Original source 

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.

Advances in lithium-metal batteries, paving the way for safer, more powerful devices      (via sciencedaily.com)     Original source 

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.

Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken      (via sciencedaily.com)     Original source 

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.

First evidence of how the Asian malaria mosquito is spreading drug-resistant malaria in Africa      (via sciencedaily.com)     Original source 

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.

Device 'smells' seawater to discover, detect novel molecules      (via sciencedaily.com)     Original source 

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.

The fascinating relationship between mice and a plant that flowers once a century in terms of seed dispersal      (via sciencedaily.com)     Original source 

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.

New algae species rewrites understanding of reef systems      (via sciencedaily.com)     Original source 

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.

Crust-forming algae are displacing corals in tropical waters worldwide      (via sciencedaily.com)     Original source 

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.
