Some areas on Mars are extremely salty, very cold, and have only a hint of oxygen - just like Earth. Yet even in the permafrost of Lost Hammer Spring in the Nunavut territory of Canada’s High Arctic, researchers have found microbes that have never been identified before. 

Using genomic and single cell microbiology methods, they examined their metabolisms and found that the microbial communities found living in Canada’s High Arctic can survive by eating and breathing simple inorganic compounds of a kind that have been detected on Mars - methane, sulfide, sulfate, carbon monoxide, and carbon dioxide. 

Some politicians and cultural activists may claim that humans are propelled by consumerism but a new paper finds that isn't true. And that it is not true is a good thing.

If we were all driven by greed, there would be no poverty. Developing nations would embrace science and have plentiful food. But the environmental strain would be tremendous.

In 1347, the Bubonic or Black Plague first entered the Mediterranean via trade ships transporting goods from the territories of the Golden Horde in the Black Sea.

The disease tore through Europe, the Middle East and northern Africa, in some cases claiming up to 60 percent of the population. It resurged throughout the next 500 years.

Scientists just published a study of what may prove to be China's most ancient human fossil. The researchers employed microCT, geometric morphometry, and classical morphology techniques to investigate the remains of the maxillary and five teeth from the skull unearthed at the Chinese site of Gongwangling, on the vast plains on the northern slopes of the Quinling Mountains (province of Shaanxi, in central China) and was discovered by the scientist Woo Ju-Kang in 1963.

Though activists try to portray farmers as slathering pesticides and fertilizer on land, anyone who has farmed know it is just the opposite; land is their greatest asset and given price competition they need to control costs and inputs as much as possible.

It's difficult to imagine that a simple dietary intervention could mean less Alzheimer’s disease but that is why observational studies and epidemiology claims are placed into the exploratory pile until science can take a look.

A new paper correlates people with a higher  red blood cell (RBC) docosahexaenoic acid (DHA levels as 49% less likely to develop Alzheimer’s disease vs. those with lower levels, especially for those carrying the ApoE4 gene, which is also a risk factor for Alzheimer's. You know that correlation is not causation so modifying two risk factors with unclear biological meaning may or not be better than doing nothing and hoping for the best.
