Discovering dust-obscured active galaxies as they grow

Thu, 27/08/2015 - 12:35pm
Astronomers have performed an extensive search for Dust Obscured Galaxies (DOGs). The research group discovered 48 DOGs, and has measured how common they are. Since DOGs are thought to harbor a rapidly growing black hole in their centers, these results give us clues for understanding the evolution of galaxies and supermassive black holes.

At the origin of language structure

Thu, 27/08/2015 - 12:35pm
There are languages that place the verb between the subject and the object (SVO order--Subject/ Verb/ Object) while others place it at the end of the trio (SOV order). The order of these elements, far from being purely decorative, influences efficiency of expression. Scientists studied the mechanism that controls the transition from the SOV form, considered the "basic" order by scientists, to the SVO order while the language is evolving, demonstrating that when the computational load on the brain is lightened, humans choose more efficient systems of communication which encourage the use of more complex grammatical structures.

What would a tsunami in the Mediterranean look like?

Thu, 27/08/2015 - 12:35pm
Researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece.

Political polarization on Twitter depends on the issue

Thu, 27/08/2015 - 12:34pm
Twitter offers a public platform for people to post and share all sorts of content, from the serious to the ridiculous. While people tend to share political information with those who have similar ideological preferences, new research demonstrates that Twitter is more than just an 'echo chamber.'

Pigments, organelles persist in fossil feathers: Shed light on original coloration of long-lost animals

Thu, 27/08/2015 - 12:34pm
An international team of researchers has found direct chemical evidence that the fossilized remains of a bird-like dinosaur still harbor melanosomes and the pigment they produced. Their study reinforces the idea that scientists can discern the coloration of long-lost animals.

Saving lives using new stent graft design

Thu, 27/08/2015 - 12:43am
Patients suffering from aneurysms that extend from their chest into their groin may be helped by a new stent graft, thanks to collaborative research. Mechanical engineers fluid flow modeling “helped validate that the configuration is delivering more well developed blood flow with the design,” according to a vascular surgeon.

HIV testing among older adults is declining, despite CDC recommendation

Thu, 27/08/2015 - 12:43am
In 2006 the Centers for Disease Control and Prevention recommended that most doctors should automatically screen all their patients, including older adults, for HIV even if they don't exhibit any symptoms. New research finds that despite this recommendation, testing among older adults has largely fallen over time.

New approach to tackling uncontrolled high blood pressure shows significant results

Thu, 27/08/2015 - 12:42am
Scientists have successfully improved blood pressure control among patients with severe intolerance to antihypertensive medication -- by using medicines in unconventional ways and treating patients with a 'stepped care' approach (where the most effective yet least intensive treatment is delivered to patients first).
