Tracking the tyrannosaur’s trail

Just outside the tiny town of Glenrock, Wyo., the footprints of a 66-million-year-old monster are cemented in stone. This fossil trackway was brought to light with the help of a Canadian paleontologist who first viewed the tracks as a 13-year-old while visiting the Glenrock Paleon Museum.

Gregarious chimps harbor richer gut microbiomes

Spending time in close contact with others means risking catching germs and getting sick. But being sociable may also help transmit ‘good’ microbes, finds a new study. Researchers monitored changes in the gut microbiomes and social behavior of chimpanzees over eight years in Tanzania. The number of bacterial species in a chimp’s GI tract increased when the chimps were more gregarious. The results help scientists understand the factors that maintain a healthy gut microbiome.

Warming climate may impact animals' ability to eat some toxic plants

University of Utah lab experiments found that when temperatures get warmer, woodrats suffer a reduced ability to live on their normal diet of toxic creosote – suggesting that global warming may hurt plant-eating animals.”This study adds to our understanding of how climate change may affect mammals, in that their ability to consume dietary toxins is impaired by warmer temperatures,” says biologist Denise Dearing, senior author of the research published online Jan. 13 in the British journal Proceedings of the Royal Society B.

Simulator-based training in veterinary medicine

Skills training of veterinary students is increasingly based on teaching simulators. This does not only allow a reduction of animal-based interventions but provides students with an opportunity for repeated and stress-free training sessions. Researchers have demonstrated that simulator-based training can be extremely efficient to achieve learning outcomes in veterinary gynaecology.

Signs of second largest black hole in the Milky Way

Astronomers using the Nobeyama 45-m Radio Telescope have detected signs of an invisible black hole with a mass of 100 thousand times the mass of the Sun around the center of the Milky Way. The team assumes that this possible ‘intermediate mass’ black hole is a key to understanding the birth of the supermassive black holes located in the centers of galaxies.

How much methane IS leaking at Porter Ranch?

A UC Davis scientist flying in a pollution-detecting airplane provided the first, and so far only, estimates of methane emissions spewing from the Aliso Canyon Natural Gas Storage Facility in Southern California since the leak began on Oct. 23, 2015.Those estimates were provided to the California Air Resources Board in November. Pilot and UC Davis project scientist Stephen Conley continues to measure emissions from the still uncontrolled leak, which has displaced thousands of residents in the affluent Porter Ranch neighborhood in northern Los Angeles. On Jan. 6, Gov. Jerry Brown declared a state of emergency in the community.To date, Conley estimates that the leak has emitted nearly 80,000 tons of methane, or about 1,000 tons per day.
