Researchers discovered strong evidence of a 55.5 million-year-old global warming event linked to a massive methane release. The 'latest Paleocene thermal maximum' led to the extinction or disappearance of deep-sea species and changed ecosystems. Further research is needed to understand this phenomenon.

Scientists at Johns Hopkins University have created a model that suggests a thin jet of relatively cold molten iron is streaming down across the liquid outer core from an area in the mid-Pacific to Earth's solid iron inner core. This 'cold front' could account for irregularities in the magnetic patterns observed over the Pacific.

A Yale research team has successfully turned supercritical carbon dioxide into a gel form, which could be used to extract oil from the ground instead of water. The new process is less expensive and more environmentally friendly than traditional methods.
Researchers at Princeton University have created ultrasmall plastic structures using a novel technique called LISA. The discovery has yielded insights into material behavior at nanoscales and has potential applications in computer memory chips, DNA sorting, and more. Refinements of the technique may lead to even smaller structures.

A Mayo Clinic researcher found that nearly 8% of female soldiers on active duty in the US Army suffer from eating disorders. The study, led by Dr. Tamara Lauder, suggests that military fitness requirements and pressure to maintain a lean physique contribute to the higher prevalence of eating disorders among women.
