PEG400 reveals parasite-only pocket that could sharpen malaria treatment

A review in Quantitative Biology demonstrates that scientists can now reliably build and combine very large pieces of DNA, making it much easier to redesign microbes such as yeast and bacteria to act as efficient "cell factories." With these advances, whole biological pathways, and even extra chromosomes, can be assembled and inserted into cells, allowing microbes to produce complex products like medicines, fuels, and chemicals more efficiently than before.

Grasslands and associated wildlife in the Great Plains of North America have declined precipitously and are now experiencing an increase in large wildfire activity. In a Journal of Wildlife Management study evaluating habitat use by lesser prairie chickens—a prairie grouse of conservation concern—before and immediately after a 2017 megafire, investigators found that the birds were forced out of formerly high-quality habitat in large, contiguous grasslands and into sub-optimal habitat and smaller

A forgotten fossil hidden inside a garden wall has turned out to be one of Australia’s most remarkable prehistoric discoveries. Scientists have now identified the 240-million-year-old amphibian, Arenaerpeton supinatus, revealing an almost perfectly preserved skeleton—complete with rare traces of skin. This ancient river predator, about 1.2 meters long, looked somewhat like a giant salamander but was bulkier and armed with fearsome fang-like teeth.

When solar storms strike Earth, they can disrupt power grids, rail systems, satellites, and even marine life. These effects arise because solar wind and geomagnetic activity disturb the magnetosphere–ionosphere system, generating electric and magnetic field variations that can resemble fainter signals from natural hazards. This risk is not theoretical.
