Plants can undergo the same extreme 'chromosome shattering' seen in some human cancers and developmental syndromes, UC Davis researchers have found. Chromosome shattering, or 'chromothripsis,' has until now only been seen in animal cells.

The process could be applied in plant breeding as a way to create haploid plants with genetic material from only one parent, said Ek Han Tan, a postdoctoral researcher in the UC Davis Department of Plant Biology and first author on the paper. Although plants don't get cancer, it might also allow cancer researchers to use the laboratory plant Arabidopsis as a model to study chromosome behavior in cancer.

A new study demonstrates that the atypical trajectory of cortical/brain development in autism spectrum disorder (ASD) extends well beyond young childhood and into late adolescence and young adulthood.

A considerable amount of work has focused on early structural brain development in ASD utilizing magnetic resonance imaging (MRI). This body of work has revealed evidence for brain overgrowth during the early postnatal years that appears largely absent later in development in ASD. Although several studies of cortical brain structure in adolescence and young adulthood in ASD have been completed, the vast majority has utilized cross-sectional (i.e., one point in time) designs.

Over geologic time, the work of rain and other processes that chemically dissolve rocks into constituent molecules that wash out to sea can diminish mountains and reshape continents.

Scientists are interested in the rates of these chemical weathering processes because they have big implications for the planet's carbon cycle, which shuttles carbon dioxide between land, sea, and air and influences global temperatures.

A new study, published online on June 8 in the journal Nature Geoscience, by a team of scientists from Stanford and Germany's GFZ Research Center for Geosciences reveals that, contrary to expectations, weathering rates over the past 2 million years do not appear to have varied significantly between glacial and interglacial periods.

Gaze following to distant space has been documented in many species such as primates, domesticated goats, several bird species, dolphins, fur seals, the red-footed tortoise and wolves. Gaze following is therefore a basic response found in many taxa. Dogs may present a special case as we find evidence that they are able to follow human gaze to objects such as food or toys, but not for the comparatively simpler task of following gaze into distant space.

Extremely poor vision can be caused by strabismus in early childhood or by a displaced optical axis.

Amblyopia is caused not by organic damage to the eyes but by the brain incorrectly fitting together the images the eyes provide. As a result, the ability to see an object in sharp focus is severely limited. This occurs in more than one in 20 of the German population, as Heike M. Elflein et al. show in a recent original article in Deutsches Ärzteblatt International (Dtsch Arztebl Int 2015; 112(19): 338-44).

The authors' study analyzed the visual acuity of over 3200 individuals aged between 35 and 44 years and determined the frequency and causes of amblyopia.

The advent of online social networks has led to the rapid development of tools for understanding the interactions between members of the network, their activity, the connections, the hubs and nodes. Science 2.0 was founded with that as one of its four pillars. But any relationship between lots of entities, be it users of Facebook or the genes and proteins in our bodies, can be analyzed with the same tools.

Now a paper shows how social network analysis can be used to understand and identify the biomarkers in our bodies for diseases, including different types of cancer.
