Researchers from the University of Basque, Spain, have conducted an experiment into different cooking oils and discovered that compounds known as aldehydes released from the oils increase the risk of neurologic degenerative diseases and several different cancers.

Two scientists from Uludag University in Turkey have examined the potential transfer of harmful phthalates from toys onto the skin of children via sweat.

A stable baseline is a prerequisite for precise, accurate and reproducible GPC/SEC analysis, especially for samples with a broad molar mass distribution. Baseline problems can include drift, wander (long-term noise), noise/spikes (short-term noise), as well as positive or negative system peaks.

The majority of the human brain is not yet fully understood and we still have a lot to learn about its workings. A group of scientists have performed a comprehensive first characterization of the human occipital lobe (primary visual cortex) and cerebellum proteomes from 12 post-mortem samples.
