Newly invented techniques which allow the real-time, real-space visualization of fleeting changes in the structure of nanoscale matter — have been used to image the evanescent electrical fields produced by the interaction of electrons and photons, and to track changes in atomic-scale structures.

Aided by next-generation DNA sequencing technology, researchers have gained insights into how more than 60 carcinogens associated with cigarette smoke bind to and chemically modify human DNA, ultimately leading to cancer-causing genetic mutations.

Like an angry dog, a volcano growls before it bites, shaking the ground and getting “noisy” before erupting. This activity gives scientists an opportunity to study the tumult beneath a volcano and may help them improve the accuracy of eruption forecasts, according to seismologists.

The most widely used human embryonic stem cell lines lack genetic diversity, a finding that raises social justice questions that must be addressed to ensure that all sectors of society benefit from stem cell advances, according to researchers.

Beauty is not only in the eye of the beholder but also in the relationship of the eyes and mouth of the beholden. The distance between a woman’s eyes and the distance between her eyes and her mouth are key factors in determining how attractive she is to others, according to new psychology research.

Researchers have generated the first comprehensive analysis of a malignant melanoma and a lung cancer genome. The results, which reveal essentially all the mutations in the genomes, will provide powerful insights into the biology of cancer and lay the foundation for understanding causation and improving prevention, detection and treatment. The ultimate aim will be to [...]
The American coot is a drab, seemingly unremarkable marsh bird common throughout North America. But its reproductive life is full of deception and violence. According to biologists, coots have evolved a remarkable set of cognitive abilities to thwart other coots that lay eggs in their neighbors’ nests.

Researchers have developed synthetic platelets from biodegradable polymers. In animal models, the synthetics attach to natural platelets and stem bleeding faster than current treatments.
