Long-term heavy drinking may age arteries over time
Heavy alcohol drinking habits over the years may prematurely age arteries, especially in men, putting them at an increased risk for heart disease, compared to consistently moderate drinkers.
Selenium deficiency promoted by climate change
As a result of climate change, concentrations of the trace element selenium in soils are likely to decrease. Because the selenium content of crops may also be reduced, the risk of selenium deficiency could be increased in many regions of the world. This was shown by a recent study which used data-mining to model the global distribution of selenium.
Poaching drives 80 percent decline in elephants in key preserve
Forest elephant populations in one of Central Africa's largest sanctuaries have declined between 78% and 81% because of poaching, a new study finds. More than 25,000 elephants in Gabon's Minkébé National Park may have been killed for their ivory between 2004 and 2014. With nearly half of Central Africa's forest elephants thought to live in Gabon, the loss of elephants from the park is a considerable setback for the preservation of the species.
Those who help each other can invade harsher environments
Through cooperation, animals are able to colonize harsher living environments that would otherwise be inaccessible, according to a new study. The research community has long believed this was the other way around -- that species in tough environments had to cooperate to survive. As a result the established view of why animals cooperate is turned upside-down.
Prospect for more effective treatment of nerve pain
Trigeminal neuralgia is characterized by sharp, lancinating pain in the teeth or facial area. The standard treatment for this chronic nerve pain can cause burdening side effects. A novel substance inhibits the pain effectively and is well tolerated, as documented by the initial results of an international study.
