Exploring the role of blood flow during cardiac events

Mon, 13/02/2017 - 8:25pm
While several circulatory system models are used today in an attempt to better understand blood flow, they still don’t account for the complex rheological behavior of blood. Because blood is a complex suspension of red and white blood cells and platelets suspended within a plasma that contains various proteins, it can exhibit complex flow behavior. Many of the models currently used ignore these complexities and assume a Newtonian behavior or a constant thickness. Researchers will now present a new approach.

Nicotine changes how nicotinic receptors are grouped on brain cells

Mon, 13/02/2017 - 8:23pm
Nicotine the primary compound found within tobacco smoke is known to change the grouping of some subtypes of nicotinic receptors, but the mechanisms for nicotine addiction remain unclear.

Surprising link between athletics and addiction

Mon, 13/02/2017 - 8:13pm
While investigating the idealized benefits between sport and addiction, researchers found that the prevalence of substance abuse in some sports communities, in fact, creates a greater risk of addictions for people already vulnerable to them. Surprised by the number of participants, researchers interviewed a range of subjects including a gymnast, a rower, a martial artist and a significant number of athletes involved in team sports -- especially hockey.

X-ray pulses reveal structure of viral cocoon

Mon, 13/02/2017 - 8:13pm
Scientists have used high-intensity X-ray pulses to determine the structure of the crystalline protein envelope of an insect virus. The tiny viruses with their crystal casing are by far the smallest protein crystals ever analyzed using X-ray crystallography. This opens up new opportunities in the study of protein structures.

Desert songbirds may face expanding threat of lethal dehydration

Mon, 13/02/2017 - 8:12pm
A new study of songbird dehydration and survival risk during heat waves in the desert Southwest suggests that some birds are at risk of lethal dehydration and mass die-offs when water is scarce, and the risk is expected to increase as climate change advances. Using physiological data, hourly temperature maps and modeling, researchers investigated how rates of evaporative water loss varied in five bird species with varied body mass.

'Achilles' heel' of key anti-cancer protein

Mon, 13/02/2017 - 6:15pm
Researchers have discovered that a protein called Importin-11 protects the anti-cancer protein PTEN from destruction by transporting it into the cell nucleus. The research suggests that the loss of Importin-11 may destabilize PTEN, leading to the development of lung, prostate, and other cancers.

Neurons support cancer growth throughout the body

Mon, 13/02/2017 - 6:15pm
Cancer cells rely on the healthy cells that surround them for sustenance. Tumors reroute blood vessels to nourish themselves, secrete chemicals that scramble immune responses, and, according to recent studies, even recruit and manipulate neurons for their own gain. This pattern holds true not just for brain cancers, but also for prostate cancer, skin cancer, pancreatic cancer, and stomach cancer.

New discovery could be a major advance for neurological diseases

Mon, 13/02/2017 - 6:14pm
The discovery of a new mechanism that controls the way nerve cells in the brain communicate with each other to regulate our learning and long-term memory could have major benefits to understanding how the brain works and what goes wrong in neurodegenerative disorders such as epilepsy and dementia. The findings will have far-reaching implications in many aspects of neuroscience.

Marine bacteria produce an environmentally important molecule with links to climate

Mon, 13/02/2017 - 6:14pm
Scientists have discovered that tiny marine bacteria can synthesize one of Earth's most abundant sulfur molecules, which affects atmospheric chemistry and potentially climate. This molecule, dimethylsulfoniopropionate is an important nutrient for marine microorganisms and is the major precursor for the climate-cooling gas, dimethyl sulfide.
