Global warming is causing regions of the Chicago Loop to sink, the color of the ocean to change, and the daily odds of being bitten by a venomous snake in Georgia to increase, with each additional degree Celsius, by 5.6 percent. Scientists at the University of Copenhagen, contrary to the Intergovernmental Panel on Climate Change findings, concluded that the Atlantic Meridional Overturning Circulation is likely to collapse this century. When comparing fuel options for international shipping, Britons strongly disfavor ammonia. It may be possible to stabilize the level of road salt in American lakes. The Anthropocene Working Group proposed that official boundary measurements for the Anthropocene be established at Ontario’s Crawford Lake. Martian rivers likely flowed into Jezero Crater for at least a million years. Paleontologists debated whether a fossil of a Repenomamus attacking a Psittacosaurus shows mammal-on-dinosaur violence, Kelvin–Helmholtz instabilities were conclusively observed at Jupiter’s magnetopause, and the supermassive black hole at the heart of the Milky Way may have forced its orbiting stellar binaries to either merge or eject one member of the pairs. A white dwarf first observed by the Zwicky Transient Facility is hydrogen on one side and helium on the other. A physicist who combined Zwicky’s tired light theory—wherein photons from distant, ancient galaxies have gradually faded, enhancing the red shift of the universe’s expansion—with Dirac’s coupling constants proposed that the Big Bang may have happened twice as long ago as previously thought.

A random-forest model can predict, from the shape and size of certain birds’ beaks, the material they use to build their nests, the king’s swan marker reported a precipitous drop in Thames cygnets, and it is extremely difficult for African cuckoos to fool fork-tailed drongos. Equids whose owners believe in animals’ capacity for emotion enjoy better health, while rats who were tickled playfully by a familiar human exhibited activity in the lateral columns of the periaqueductal gray. AIs identify texts written by non-native English speakers as having been written by other AIs. Phylogenetic analysis allowed for the dating of the Proto-Indo-European language to around 8,100 years ago. The first voyagers to travel from Tahiti to New Zealand required 3.3 to 4.8 times more energy for thermoregulation than those who traveled to Hawaii, which may account for the bulkier bodies of East Polynesians. Hospitalization for childhood burns correlates with poorer academic performance in female adolescents. Aggression can be a product of superior, not inferior, self-control. Creative people find their idle thoughts less boring. Somatic NRXN1 mutations can contribute to schizophrenia, and MdLAZY1A causes the branches of apple trees to weep.

Parasitic hairworms are the only animals whose cells lack cilia. Surgically joining the circulatory system of an old mouse to that of a young mouse allows the old mouse to live longer. Retrieving human eggs on sunny days results in a higher rate of live births. A paternally inherited gene in mice attempts to compel pregnant mothers to allocate maximal resources to the fetus. Postmenopausal orcas help protect their sons, but not their daughters or grandchildren, from socially inflicted injuries. Nearly half the orchids in a survey deceived pollinators rather than rewarded them. Researchers completed the first oncological trial of intravenous mistletoe extract.
