The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.

Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate during the lifetime of an individual. In humans, this observation has led to the development of epigenetic clocks, which are now extensively used as biomarkers of aging. While these clocks work accurately from birth until death, they are set back to zero in each new generation. Now, an international team shows that epigenetic clocks not only exist in plants, but that these clocks keep ticking accurately over many generations.

For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.

The Allpahuayo-Mishana National Reserve in Peru has often been described as the most biodiverse rainforest in the world. For example, in recent decades, scientist have discovered several new bird species from the region. Researchers from the University of Turku in Finland have studied the insect biodiversity in Allpahuayo-Mishana for over 20 years. In their latest study, the scientist described a new wasp genus, Capitojoppa, to science.

Wildfires in California, exacerbated by human-driven climate change, are getting more severe. To better manage them, there's a growing need to know exactly what fuels the blazes after they ignite. Scientists now report that one of the chief fuels of wildfires in California's Sierra Nevada mountains is the decades-old remains of large trees.

Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In collaboration with the Leibniz Institute of Photonic Technologies in

Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.

Plants are often attributed with abilities similar to those known in the animal or human world. Trees are said to have feelings and can therefore care for their offspring, like mothers. Researchers analyzed the claims in two popular publications on forests and reached the conclusion that conjecture is equated with fact. They warn against 'anthropomorphizing' plants.

A team of international researchers has uncovered further clues in the quest for insights into the nature of dark matter. The key to understanding this mystery could lie with the dark photon, a theoretical massive particle that may serve as a portal between the dark sector of particles and regular matter.

The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.

• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.
