EAST LANSING, Mich. — Most college students in the United States do not grasp the scientific basis of the carbon cycle – an essential skill in understanding the causes and consequences of climate change, according to research published in the January issue of BioScience.

The study, whose authors include several current and former researchers from Michigan State University, calls for a new way of teaching – and, ultimately, comprehending – fundamental scientific principles such as the conservation of matter. (more…)

When their romantic partners are not quintessentially masculine, women in their fertile phase are more likely to fantasize about masculine-looking men than are women paired with George Clooney types.

But women with masculine-looking partners do not necessarily become more attracted to their partners, a recent study co-authored by a University of Colorado at Boulder researcher concludes. (more…)

Persistent lack of oxygen in Earth’s oceans affected animal evolution

The oceans became oxygen-rich as they are today about 600 million years ago, during Earth’s Late Ediacaran Period. Before that, most scientists believed until recently, the ancient oceans were relatively oxygen-poor for the preceding four billion years. (more…)

Cancer cells reproduce by dividing in two, but a molecule known as PML limits how many times this can happen, according to researchers lead by Dr. Gerardo Ferbeyre of the University of Montreal’s Department of Biochemistry. The team proved that malignant cancers have problems with this molecule, meaning that in its absence they can continue to grow and eventually spread to other organs. Importantly, the presence of PML molecules can easily be detected, and could serve to diagnose whether a tumor is malignant or not. (more…)
