News at a glance: ‘Cherry-picked’ vaccine guidance, AI-written papers, and an apology for prisoner research
ENVIRONMENT Utah’s Great Salt Lake may dry up within 5 years North America’s largest saline lake could be gone by 2028 if water inflows are not restored, researchers warned last week. The Great Salt Lake in Utah has lost nearly three-quarters of its water and 60% of its surface area since 1950, a report from 32 scientists at multiple institutions concludes, and a recent drought has accelerated the losses. To restore the lake, farmers, homeowners, and others will need to reduce the amount of water they take from feeder streams by 30% to 50% . If they don’t, the continent could lose a key habitat ...

Forensic entomology application in China: Four case reports
We present four cases that use entomological data to estimate postmortem interval (PMI). In the first case, the body was found in an outdoor environment at 26 °C and was at the fresh stage. However, the PMImin estimated using maggots collected from the corpse was more than 68 h. This was certainly an incorrect estimation because the degree of the body decomposition was light, and it may have been caused by flies invading the corpse before death occurred. In the second case, a corpse of an adult male was found in a semi-closed room, and the body was highly decomposed and mummified. In this case, we used Dermestes macul...

Skin artefacts due to post-mortem damage caused by Notiothauma reedi: A insect of forensic importance in forest communities of Chile
This study provides preliminary results on the role of this species in the decomposition of carcasses in native forests and exotic plantations in southern Chile and on the skin lesions that it causes, which should be taken into account when cadavers are found under conditions similar to those described above. In light of these findings, N. reedi could be a new bioindicator of forensic utility in the forest communities of southern Chile.

First Record of the Larval Endoparasitoid Tachinaephagus zealandicus (Hymenoptera: Encyrtidae) From Fly Hosts Developing on Burnt Remains and in Pennsylvania
Adults of the gregarious larval endoparasitoid Tachinaephagus zealandicus Ashmead (Hymenoptera: Encyrtidae) were collected from two species of carrion-inhabiting flies, Phormia regina Meigen (Diptera: Calliphoridae) and Hydrotaea aenescens Wiedemann (Muscidae), associated with the burnt remains of a domesticated pig, Sus scrofa L. (Artiodactyla: Suidae), during late summer in south central Pennsylvania. This represents the first reported occurrence of the wasp in the state and only the second in the mid-Atlantic region. Collection from P. regina is a new host record for T. zealandicus and also the first for this parasitoid...

Entomofaunal Succession Patterns on Burnt and Unburnt Rabbit Carrion
The influence of burning on the decomposition of rabbit carcasses and on insect succession was investigated in three different habitats (agricultural, desert, and urban) in order to provide data for estimating the postmortem interval (PMI). Each site had six carcasses divided into two groups of three rabbits, with the carcasses in one group being partially burned, while the others were not burned. Carrion reached the dry stage within 5 d in the desert and urban habitats and 13 d in the agricultural habitat. The unburnt and burnt carcasses also decomposed at a similar rate in the three study habitats. Adult dipteran and col...
