When good habits go bad
2013-02-16
BOSTON, MA -- Learning, memory and habits are encoded in the strength of connections between neurons in the brain, the synapses. These connections aren't meant to be fixed, they're changeable, or plastic.
Duke University neurologist and neuroscientist Nicole Calakos studies what happens when those connections aren't as adaptable as they should be in the basal ganglia, the brain's "command center" for turning information into actions.
"The basal ganglia is the part of the brain that drives the car when you're not thinking too hard about it," Calakos said. It's also ...
Mussels cramped by environmental factors
2013-02-16
The fibrous threads helping mussels stay anchored – in spite of waves that sometimes pound the shore with a force equivalent to a jet liner flying at 600 miles per hour – are more prone to snap when ocean temperatures climb higher than normal.
At the American Association for the Advancement of Science meeting in Boston, Emily Carrington, a University of Washington professor of biology, reported that the fibrous threads she calls "nature's bungee cords" become 60 percent weaker in water that was 15 degrees F (7 C) above typical summer temperatures where the mussels were ...
Mussel-inspired 'glue' for surgical repair and cancer drug delivery
2013-02-16

Northwestern University's Phillip B. Messersmith will discuss his research in a talk titled "Mussel-Inspired Materials for Surgical Repair and Drug Delivery" at the American Association for the Advancement of Science (AAAS) annual meeting in Boston. His presentation is part of the symposium "Translation of Mussel Adhesion to Beneficial ...
Using transportation data to predict pandemics
2013-02-16
In a world of increasing global connections, predicting the spread of infectious diseases is more complicated than ever. Pandemics no longer follow the patterns they did centuries ago, when diseases swept through populations town by town; instead, they spread quickly and seemingly at random, spurred by the interactions of 3 billion air travelers per year.
A computational model developed by Northwestern University's Dirk Brockmann could provide better insight into how today's diseases might strike. Brockmann, an associate professor of engineering sciences and applied mathematics ...
Historic legacy of lead pollution persists despite regulatory efforts
2013-02-16

Modern life may cause sun exposure, skin pigmentation mismatch
2013-02-16
UNIVERSITY PARK, Pa. -- As people move more often and become more urbanized, skin color -- an adaptation that took hundreds of thousands of years to develop in humans -- may lose some of its evolutionary advantage, according to a Penn State anthropologist.
About 2 million years ago, permanent dark skin color imparted by the pigment -- melanin -- began to evolve in humans to regulate the body's reaction to ultraviolet rays from the sun, said Nina Jablonski, Distinguished Professor of Anthropology.
Melanin helped humans maintain the delicate balance between too much ...
Flow of research on ice sheets helps answer climate questions
2013-02-16
UNIVERSITY PARK, PA. -- Just as ice sheets slide slowly and steadily into the ocean, researchers are returning from each trip to the Arctic and Antarctic with more data about climate change, including information that will help improve current models on how climate change will affect life on the earth, according to a Penn State geologist.
"It is not just correlation, it is causation," said Richard Alley, Evan Pugh Professor of Geosciences. "We know that warming is happening and it's causing the sea levels to rise and if we expect more warming, we can expect the sea levels ...
Academics grapple with balancing their research with the need to communicate it to the public
2013-02-16
BOSTON – Researchers today more than ever focus their work on real-world problems, often times making their research relevant to the public locally, regionally and sometimes nationally. But engaging the public in their research can be a daunting task for researchers both professionally and personally.
Leah Gerber, an Arizona State University associate professor in the School of Life Sciences and a senior sustainability scientist in the School of Sustainability, has identified impediments to productive science communication and she shared her recommendations at the 2013 ...
Deja vu all over again? Cultural understanding vs. horrors of eugenics
2013-02-16
Why is the world so full of "morons" and "degenerates" and what, if anything, can be done to fix them?
These are questions that Robert W. Sussman, PhD, a professor of anthropology in Arts & Sciences at Washington University in St. Louis, will explore Feb. 15 as he addresses the 2013 meeting of the American Association for the Advancement of Science (AAAS) in Boston, Mass. — one of the world's largest gatherings of scientific researchers.

To feed the world, give women equal rights
2013-02-16
Around the world, at least a billion people are hungry or need better diets. To feed a global population projected to reach 9.6 billion by 2050, we will need to increase food production by as much as 70 percent, most analysts believe.
Achieving that goal requires civilization to address overpopulation and overconsumption through a bottom-up movement focused on agricultural, environmental and demographic planning, among other strategies, argues Stanford Woods Institute Senior Fellow Paul Ehrlich (Biology). A crucial first step is to give equal rights to women worldwide, ...
Researchers at St. Michael's Hospital test tool for screening cancer patients for malnutrition
2013-02-16
TORONTO, Feb. 15, 2013—Considering the many things a cancer patient has to think about, it's easy to understand why maintaining proper nutrition may not be top of mind.
This can be true, too, at busy outpatient settings where it's often difficult to find the time and resources to test cancer patients for malnutrition.
However, researchers at St. Michael's Hospital have found a shorter version of a commonly used nutrition-assessment tool does the job effectively and can potentially improve outcomes for cancer patients.
"The full-length test for malnutrition is too ...

Bunions bothering you? How about lower back pain, or impacted wisdom teeth?
As we humans evolved over the millennia to walk on two legs, grow larger brains and shorter jaws, bear big babies and live longer, we've also experienced some negative consequences on our way to becoming the world's most successful primate, at nearly 7 billion strong.
But keeping our evolutionary history in mind can help us better deal with issues from obesity to difficult childbirth in a much more productive way, according to Karen Rosenberg, professor and chair of the Department of Anthropology ...
