UCLA researchers find evidence for water ice deposits and organic material on Mercury
Planetary scientists have identified water ice and anomalously dark deposits within permanently shadowed regions at Mercury's north pole. They conclude the newly discovered black deposits are a thin dark crust of residual organic material brought to the planet over the past several million years by water-rich asteroid and comet impacts.

Brief interventions can help college students return to a healthy lifestyle
A new study from the University of Missouri has found that a brief intervention, sometimes as little as 30 minutes, can help put students back on the right track to a healthy lifestyle -- a change that can impact the rest of their lives.

Marketing analytics ups Fortune 1000 return on assets 8 percent, says operations research study
Fortune 1000 companies that increase their use of marketing analytics improve their return on assets an average 8 percent and as much as 21 percent, with returns ranging from $70 million to $180 million in net income, according to a paper written by two key members of the Institute for Operations Research and the Management Sciences.

More evidence for an ancient Grand Canyon
For over 150 years, geologists have debated how and when one of the most dramatic features on our planet -- the Grand Canyon -- was formed. New data unearthed by researchers at the California Institute of Technology builds support for the idea that conventional models, which say the enormous ravine is five to six million years old, are way off.

Defining career paths in health systems improvement
Among numerous programs aimed at improving the quality and efficiency of the US health care system, training the next generation of experts needed to help lead these efforts has received inadequate, according to three physicians writing in the January 2013 issue of Academic Medicine. Their article proposes a framework for career development in what they call "health systems improvement."

Proteins that work at the ends of DNA could provide cancer insight
New insights into a protein complex that regulates the very tips of chromosomes could improve methods of screening anti-cancer drugs. University of Illinois researchers determined the binding mechanism of proteins that protect and regulate telomeres, segments of repeating DNA units that cap the ends of chromosomes and a key target of cancer researchers.

Diabetics with cancer dangerously ignore blood sugar
When people with Type 2 diabetes are diagnosed with cancer -- for which they are at higher risk -- they ignore their diabetes to focus on cancer. But high blood sugar is more likely to kill them. When they received diabetes education after a cancer diagnosis, however, they were more likely to monitor their blood sugar and had fewer visits to the emergency room, fewer hospital admissions and lower health care costs.

Young surgeons face special concerns with operating room distractions
A study has found that young, less-experienced surgeons made major surgical mistakes almost half the time during a "simulated" gall bladder removal when they were distracted by noises, questions, conversation or other commotion in the operating room.

Birds may spread, not halt, fever-bearing ticks
Turkey raises and releases thousands of non-native guineafowl to eat ticks that carry the deadly Crimean-Congo hemorrhagic fever virus. Yet research suggests guineafowl eat few ticks, but carry the parasites on their feathers, possibly spreading the disease they were meant to stop, says a Turkish biologist working at the University of Utah.

Autism severity may stem from fear
New research on autism shows that children with the diagnosis struggle to let go of old, outdated fears. Even more significantly, the study found that this rigid fearfulness is linked to the severity of classic symptoms of autism, such as repeated movements and resistance to change.

Predicting material fatigue
A small crack in a metal wheel caused Germany's worst-ever rail accident -- the 1998 Eschede train disaster. The problem: it was practically impossible to detect damage of that nature to a metal by inspecting it externally. But now scientists have succeeded in making material fatigue visible. They designed new synthetic materials that emit light to report high mechanical stress.

Adapting fish defenses to block human infections
Living in an environment teaming with bacteria and fungi, fish have evolved powerful defenses, including antimicrobial peptides located in their gills. Undergraduate researchers at Worcester Polytechnic Institute are studying the biology and mechanics of one of those peptides with the aim of creating engineered surfaces that can kill bacteria responsible for foodborne illnesses and hospital-acquired infections. The team reports its latest findings online in the journal ACS Applied Materials & Interfaces.

Post-divorce journaling may hinder healing for some
Following a divorce or separation, many people are encouraged by loved ones or health-care professionals to keep journals about their feelings. But for some, writing in-depth about those feelings immediately after a split may do more harm than good, according to new research published in Clinical Psychological Science.

The beginning of everything: A new paradigm shift for the infant universe
A new paradigm for understanding the earliest eras in the history of the universe has been developed by scientists at Penn State University. The new paradigm shows, for the first time, that the large-scale structures we now see in the universe evolved from fundamental fluctuations in the essential quantum nature of "space-time," which existed even at the very beginning of the universe.

Children with higher intelligence less likely to report chronic widespread pain in adulthood
A UK-based study team has determined that there is a correlation between childhood intelligence and chronic widespread pain (CWP) in adulthood, according to a new study published in the December issue of PAINŽ. About 10-15 percent of adults report CWP, a common musculoskeletal complaint that tends to occur more frequently among women and those from disadvantaged socioeconomic backgrounds. CWP is a core symptom of fibromyalgia and is one of the most common reasons for consulting a rheumatologist.

Oceanic crust breakthrough: Solving a magma mystery
Oceanic crust covers two-thirds of the Earth's solid surface, but scientists still don't entirely understand the process by which it is made. Analysis of more than 600 samples of oceanic crust by a team including Carnegie's Frances Jenner reveals a systemic pattern that alters long-held beliefs about how this process works, explaining a crucial step in understanding Earth's geological deep processes.

Studies by scientist Mark Ibekwe suggest that in some parts of California, pathogens in local waterways are more often carried there via runoff from urban areas, not from animal production facilities.
