Freshwater Biology
Alaska fish adjust to climate change by following the food
Not all species may suffer from climate change. A new analysis shows that Dolly Varden, a species of char common in southeast Alaska, adjust their migrations so they can keep feasting on a key food source -- salmon eggs -- even as shifts in climate altered the timing of salmon spawning.

Early exposure to antidepressants affects adult anxiety and serotonin transmission
Now, a UCLA team has studied early developmental exposure to two different antidepressants, Prozac and Lexapro, in a mouse model that mimics human third trimester medication exposure. They found that, although these serotonin-selective reuptake inhibiting antidepressants were thought to work the same way, they did not produce the same long-term changes in anxiety behavior in the adult mice.

New technique reveals immune cell motion
Neutrophils, cells recruited by the immune system to fight infection, need to move through a great variety of tissues. New research shows how neutrophils move through confined spaces in the body. A new system can mimic tissues of different densities and stiffness, enabling improved development and testing of drugs.

The VuePod: Powerful enough for a gamer, made for an engineer
It's like a scene from a gamer's wildest dreams: 12 high-definition, 55-inch 3-D televisions all connected to a computer capable of supporting high-end, graphics-intensive gaming. On the massive screen, images are controlled by a Wii remote that interacts with a Kinnect-like Bluetooth device (called SmartTrack), while 3-D glasses worn by the user create dizzying added dimensions.

Reducing emergency surgery cuts health care costs
In new findings published online in the journal Annals of Surgery on Dec. 19, 2014, researchers determined the hospital costs and risk of death for emergency surgery and compared it to the same operation when performed in a planned, elective manner for three common surgical procedures: abdominal aortic aneurysm repair, coronary artery bypass graft and colon resection.

Technophobia may keep seniors from using apps to manage diabetes
Despite showing interest in web or mobile apps to help manage their type 2 diabetes, only a small number of older adults actually use them, says a new study from the University of Waterloo. Approximately 2.2 million Canadians are living with type 2 diabetes, 2 million of whom are age 50 or older.

Yellowstone's thermal springs -- their colors unveiled
Researchers at Montana State University and Brandenburg University of Applied Sciences in Germany have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus. The model, and stunning pictures of the springs, appear today in the journal Applied Optics.

Televised medical talk shows: Health education or entertainment?
Millions of viewers around the world watch the televised medical talk programs 'The Dr. Oz Show' and 'The Doctors' for medical advice, but how valuable are the recommendations they receive? In a first of its kind study, researchers from the University of Alberta have examined the recommendations given on those two shows to see if there is believable evidence to back up the claims presented. The results were revealing.

A polymorphism and the bacteria inside of us help dictate inflammation, antitumor activity
A common polymorphism can lead to a chain of events that dictates how a tumor will progress in certain types of cancer, including a form of breast cancer as well as ovarian cancer, according to new research from The Wistar Institute that was published online by the journal Cancer Cell. The research reveals a more explicit role about the symbiotic relationship humans have with the various bacteria that inhabit our body and their role during tumor progression.

High blood sugar in young children with type 1 diabetes linked to changes in brain growth
Investigators have found that young children with type 1 diabetes have slower brain growth compared to children without diabetes. A new study, published in the December issue of Diabetes, now available ahead of print, suggests that continued exposure to hyperglycemia, or high blood sugars, may be detrimental to the developing brain. The research was supported by the National Institutes of Health.

Helping parents understand infant sleep patterns
Most parents are not surprised by the irregularity of a newborn infant's sleep patterns, but by six months or so many parents wonder if something is wrong with their baby or their sleeping arrangements if the baby is not sleeping through the night. Health-care providers, specifically nurse practitioners, can help parents understand what 'normal' sleep patterns are for their child, according to researchers.

Hermit creepy crawlies: Two new taxa of wood-feeding cockroach from China
Scientists from the Southwest University, Chongqing, China, have found a new species and a new subspecies of cockroach. What makes these creepy crawlies distinctive from the cockroaches most of us know is that they don't infest houses, on the contrary they prefer to live a hermit life hidden away drilling logs, far away from human eyes. The study was published in the open-access journal ZooKeys.

New challenges for ocean acidification research
To continue its striking development, ocean acidification research needs to bridge between its diverging branches towards an integrated assessment. This is the conclusion drawn by Professor Ulf Riebesell from the Helmholtz Centre for Ocean Research Kiel and Dr. Jean-Pierre Gattuso from the French Centre National de la Recherche Scientifique and Universite Pierre et Marie Curie. In a commentary in the journal Nature Climate Change, the two internationally renowned experts reflect on the lessons learned from ocean acidification research and highlight future challenges.

Trade winds ventilate the tropical oceans
Long-term observations indicate that the oxygen minimum zones in the tropical oceans have expanded in recent decades. The reason is still unknown. Now scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Collaborative Research Centre 754 'Climate - Biogeochemical Interactions in the Tropical Ocean' have found an explanation with the help of model simulations: A natural fluctuation of the trade winds. The study has been published in the international journal Geophysical Research Letters.

A 'GPS' for molecules
In everyday life, the global positioning system can be employed to reliably determine the momentary location of one en route to the desired destination. Scientists from the Institute of Physical and Theoretical Chemistry of the University of Bonn have now developed a molecular 'GPS' with which the whereabouts of metal ions in enzymes can be reliably determined. Such ions play important roles in all corners of metabolism and synthesis for biological products. The 'molecular GPS' is now being featured in the journal Angewandte Chemie.
