Penn Researchers Answer Question about Nematode Behavior: Nature, Nurture, or Physics?

blurb: 
Nature versus nurture is an age-old question in biology, centering on whether a given trait is determined by an organism’s genes or by its environment. Most times the answer is “both,” but research at the University of Pennsylvania has found one trait in particular that is not easily described by either.

Nature versus nurture is an age-old question in biology, centering on whether a given trait is determined by an organism’s genes or by its environment. Most times the answer is “both,” but research at the University of Pennsylvania has found one trait in particular that is not easily described by either.

Blacklegged Tick Populations Have Expanded Via Migration, Penn Biologists Show

blurb: 
In a new study, biologists from the University of Pennsylvania found that blacklegged ticks moved into new areas of the Northeast from established populations, mainly through short-distance, local moves. The results shed light on patterns of disease spread and could have implications for strategies to control ticks in order to reduce disease.

Lyme disease cases are on the rise, with diagnoses occurring in areas that were historically Lyme-free. Scientists attribute the spread to the fact that populations of blacklegged ticks, which carry the bacteria that causes the disease, now flourish in areas once thought to be devoid of ticks.

Penn Team Identifies Gene Responsible for Some Cases of Male Infertility

blurb: 
Oftentimes men with a type of infertility called azoospermia don’t know the underlying cause of their condition. But new research led by University of Pennsylvania scientists suggests that mutations in an X chromosome gene called TEX11 are responsible for a significant number of cases of infertility — an estimated 1 percent of cases of non-obstructive azoospermia.

In the most severe form of male infertility, men do not make any measurable levels of sperm. This condition, called azoospermia, affects approximately 1 percent of the male population and is responsible for about a sixth of cases of male infertility.

Penn Research Helps Show That Attention, Imagination Equally Important for Creativity

The role that attention plays in generating new and useful ideas is controversial among neuroscientists. Some neuroimaging studies have shown that creativity involves more cognitive control, or focused attention. Other studies have shown it involves less.

In Social Networks, Group Boundaries Promote the Spread of Ideas, Penn Study Finds

blurb: 
In a new study, the University of Pennsylvania’s Damon Centola shows how social networks form and what that means for the ideas that will spread across them.

Social networks affect every aspect of our lives, from the jobs we get and the technologies we adopt to the partners we choose and the healthiness of our lifestyles. But where do they come from?

Penn Medicine Study Finds Participation in Research Studies Not Detrimental to Preterm Infants

Premature babies who are enrolled in clinical trials for therapies to treat and prevent complications from preterm birth are no more likely to die or experience poor outcomes than babies who are not trial participants, according to a retrospective analysis of more than 5,000 babies born before 29 weeks of gestation.

Protein "Comet Tails" Propel Cell Recycling Process, Penn Study Finds

Several well-known neurodegenerative diseases, such as Lou Gehrig’s (ALS), Parkinson's, Alzheimer's, and Huntington's disease, all result in part from a defect in autophagy – one way a cell removes and recycles misfolded proteins and pathogens.
