The ability of rainforests to store carbon can decrease in pace with climate change. This is due to photosynthesis rates in the leaves of rainforest species falling at higher temperatures and the trees' natural cooling systems failing during droughts. Increased heat threatens especially the species that store most carbon.

Trapped inside the shoreline of a bay, the resonant interactions of a tsunami with regular waves can prolong the tsunami disturbance. For the 2021 magnitude 7 Acapulco, Mexico earthquake and tsunami, edge waves in the bay and the short continental shelf also had a surprisingly significant effect on the tsunami's duration, according to a new study.

Researchers have devised a method to determine the impact of climate change on the supply and variability of local renewable energy. An increase in unusual weather patterns related to climate change means the demand for power and the availability of solar, hydro and wind energy can all become more variable.

An underutilized natural resource could be just what the airline industry needs to curb carbon emissions. Researchers report success in using lignin as a path toward a drop-in 100% sustainable aviation fuel. Lignin makes up the rigid parts of the cell walls of plants. Other parts of plants are used for biofuels, but lignin has been largely overlooked because of the difficulties in breaking it down chemically and converting it into useful products.

Even small objects, such as dust and leaves, can block sunlight from reaching solar cells, and understanding how the loss of incoming radiation affects power output is essential for optimizing photovoltaic technology. Researchers explore how different shade conditions impact performance of single solar cells and two-cell systems connected in series and parallel. They found that the decrease in output current of a single cell or two cells connected in parallel was nearly identical to the ratio of shade to sunlight. However, for two cells running in series, there was excess power loss.

A recent study in Japan has found that reared ambrosia beetles, Euwallacea interjectus, can have symbiotic fungi different to those found in the wild. These findings suggest biocontrol implications for pest beetles that damage valuable crop trees such as fig trees.

It was the money that grew on trees. Said to be a gift from the gods, cacao for the ancient Maya was considered sacred, used not only as currency, but in special ceremonies and religious rituals. It's the progenitor plant of chocolate, and notions of luxury are embedded in its lore.

Using data from the Gaia space telescope, a team has shown that large parts of the Milky Way's outer disk vibrate. The ripples are caused by a dwarf galaxy, now seen in the constellation Sagittarius, that shook our galaxy as it passed by hundreds of millions of years ago.
