Direct power generation from methylcyclohexane using solid oxide fuel cells      (via sciencedaily.com)     Original source 

Methylcyclohexane is very promising as a hydrogen carrier that can safely and efficiently transport and store hydrogen. However, the dehydrogenation process using catalysts has issues due to its durability and large energy loss. Recently, researchers have succeeded in using solid oxide fuel cells to generate electricity directly from methylcyclohexane and recover toluene for reuse. This research is expected to not only reduce energy requirements but also explore new chemical synthesis by fuel cells.

The physics of fat droplets reveal DNA danger      (via sciencedaily.com) 

Researchers have looked beyond biochemistry to publish groundbreaking work on the physics of fat droplets found inside many types of cells, revealing them to be a potential threat to a cell's nucleus.They have discovered fat-filled lipid droplets' surprising capability to indent and puncture the nucleus, the organelle which contains and regulates a cell's DNA. The stakes of their findings are high: a ruptured nucleus can lead to elevated DNA damage that is characteristic of many diseases, including cancer.

Wastewater pipe dig reveals 'fossil treasure trove'      (via sciencedaily.com)     Original source 

A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.

Emperor penguin colonies experienced unprecedented breeding failure in a region of Antarctica where there was total sea ice loss in 2022. The discovery supports predictions that over 90% of emperor penguin colonies will be quasi-extinct by the end of the century, based on current global warming trends.

New approach to nongenetic T-cell-based immunotherapy      (via sciencedaily.com) 

Immunotherapies for cancer aim to induce the immune system to combat cancer cells more effectively. A research team has now described a new, modular strategy for T-cell-based immunotherapy that manages to work without complex genetic modifications. Modulation of cell-cell communications through an ingenious regulatory circuit using various small, specially folded DNA molecules (aptamers) causes cancer cells to directly activate their mortal enemies, T cells.

Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.

Fungus gnats as pollinators not pests      (via sciencedaily.com)     Original source 

Many plants and crops rely on insects to pollinate them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded as pests, in plant diversity and evolution.
