The fight against tooth decay gets help with a new smart material
When patients go to the dentist to fill a cavity, they're trying to solve a problem -- not create a new one. But many dental patients get some bad news: bacteria can dig under their tooth-colored fillings and cause new cavities, called recurrent caries. U of T researchers designed a novel solution: a filling material with tiny particles containing antimicrobial drugs, designed to stop bacteria in its tracks.

Newborns or survivors? The unexpected matter found in hostile black hole winds
The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers since they were discovered more than a decade ago. Molecules trace the coldest parts of space, and black holes are the most energetic phenomena in the universe, so finding molecules in black hole winds was like discovering ice in a furnace. A new theory predicts the molecules are born in the winds with unique properties that enable them to adapt to and thrive in the hostile environment.

Scientists identify brain region in mice that keeps the body from losing its balance

Scientists identify brain region in mice that keeps the body from losing its balance
New research reveals how a small part of the brain singlehandedly steadies the body if it is thrown off balance. The study in mice found that this region accomplishes this by moving muscles in a two-step response that first widens the animal's center of gravity, and then strengthens and stabilizes its limb muscles and joints. These findings offer insight into the mechanics of how animals stay upright when unexpected changes occur beneath their feet.

Running away from carbon dioxide: The terminal connection
Like us, fish need oxygen, and swimming through a patch of carbon dioxide turns out not to be a pleasant experience. Instead, they prefer to avoid carbon dioxide altogether. Researchers have discovered a neuronal pathway that makes this behavior possible.

Inappropriate antibiotic prescribing differs by patient age, insurance, race
A patient's age and race are associated with risk of receiving an unneeded antibiotic prescription for upper respiratory conditions caused by viruses, according to a new study. Additionally, the study found that advanced practice providers, such as nurse practitioners and physician assistants, are 15 percent more likely than physician providers to prescribe antibiotics to adults.

Pancreatic cancer: Gene duplication explains tumor aggressiveness
Pancreatic cancer is a form of cancer associated with the highest mortality rates in the world. Genetic changes that could explain his aggressiveness and early metastasis had not been found yet. A team has now shown that those characteristics can be explained by specific gene amplifications which occur along various evolutionary pathways of the cancer. Based on this discovery, they have derived basic principles underlying the biology of pancreatic cancer.

E-cigarette flavors are toxic to white blood cells, warn scientists
A new study adds to growing evidence on the harmful health effects of e-cigarettes. The study finds that exposure to commonly used e-cigarette flavoring chemicals and liquids can cause significant inflammation to monocytes, a type of white blood cell. Moreover, many flavoring compounds are toxic, with cinnamon, vanilla and buttery flavors among the worst. It also finds that mixing e-cigarette flavors has a much worse effect than exposure to just one.

New computational method reveals chemoresistance drug targets
The methylation of deoxycytosine to form 5-methylcytosine (5mC) is an important feature of cancer. Extensive DNA methylation and transcription analyses have provided large quantities of data, but it is challenging to identify critical genes related to cancer development from these data. Researchers in Japan have developed a new mathematical method to extract appropriate information from the data, and successfully identified the gene TRAF4 as a key candidate for conferring resistance to anti-cancer drugs in gastrointestinal cancer.

UK regional weather forecasts could be improved using jet stream data
Weather forecasters could be able to better predict regional rainfall and temperatures by using North Atlantic jet stream data, according to new research. Climate scientists examined the relationship between changes in North Atlantic atmospheric circulation -- or jet stream -- and UK regional weather variations during summer and winter months over the past 65 years, and found that the jet stream changes were significantly associated with variations in regional rainfall and temperatures.

Long-term opioid use has dropped among US military veterans
A new study in the Journal of General Internal Medicine, published by Springer, shows that opioid prescribing has dropped after a peak in 2012. Lead author Katherine Hadlandsmyth of the Iowa City VA Healthcare System and the University of Iowa in the US further noted that the decline was mostly due to decreases in long-term opioid prescribing, which carries much greater risk for harmful side effects, addiction and overdose, relative to short-term prescribing.

Coal phase-out: Announcing CO2-pricing triggers divestment
Putting the Paris climate agreement into practice will trigger opposed reactions by investors on the one hand and fossil fuel owners on the other hand. A new study now finds that on balance, divestment beats the so-called 'green paradox' if substantial carbon pricing is credibly announced. Consequently, overall CO2 emissions would be effectively reduced.

Despite increasing the amount of residential energy demand, the decrease in travel and use of non-residential spaces was responsible for a net 1,700 trillion bTU in energy savings for the United States in 2012, 1.8 percent of the national total.
