When the threatened European eels cross the Atlantic Ocean to get to the Sargasso Sea to spawn, they swim in deep water. But this does not protect them from predators, researchers from the University of Southern Denmark report: Even in deep water the eels are hunted and eaten. Fuente :...

Love has inspired timeless songs and sonnets -- as well as a few less-than-timeless romantic comedies. Now the chemistry of love is the subject of the latest episode of the American Chemical Society's Reactions YouTube series (formerly Bytesize Science). Just in time for Valentine's Day, the video is available at...

Computational biologists from the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna show that averaging is not always a good thing when it comes to analyzing protein crystal structures. The recent publication by Bojan Zagrovic and his team in Nature Communications shows that protein...

Greenhouse-gas induced warming and megapolitan expansion are both significant drivers of our warming planet. Researchers are now assessing adaptation technologies -- such as cool roofs, green roofs and hybrids of the two -- that could help us acclimate to these changing realities. Now a team of...

Primary effusion lymphoma (PEL) is a rare B-cell neoplasm distinguished by its tendency to spread along the thin serous membranes that line body cavities without infiltrating or destroying nearby tissue. By growing PEL cells in culture and analyzing the secretome (proteins secreted into...
