Evidence for historic global warming published in Science

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.

Earth's core may contain 'cold front' of molten iron

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.

Scientists discover how cells 'catch' a cold

Researchers at Brookhaven National Laboratory have discovered the molecular mechanism by which adenovirus binds to human cells, paving the way for the development of drugs that block infection. This breakthrough could lead to more effective vaccines and targeted therapies for viral infections.

Researchers turn carbon dioxide into gel

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.

Scientists discover how to make nanostructures assemble themselves

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.

New tool for comparative gene studies

A new technique allows scientists to introduce desired genes directly into embryonic cells using the baculovirus, enabling the study of gene function in non-model organisms. This method has shown promising results in fruit flies, beetles, and other species, offering a breakthrough for understanding developmental processes.

New target identified for chronic pain therapy

Researchers have discovered a new target for treating chronic pain by disabling specific nerve cells that send pain signals to the brain. The study found that combining substance P with saporin can significantly reduce pain sensitivity, even when administered after neuropathic pain has developed.
