An international team of researchers has found evidence that the steam and heat from volcanoes and heated rocks allowed many species of plants and animals to survive past ice ages, helping scientists understand how species respond to climate change.

The research could solve a long-running mystery about how some species survived and continued to evolve through past ice ages in parts of the planet covered by glaciers.

The team, led by Dr Ceridwen Fraser from the Australian National University and Dr Aleks Terauds from the Australian Antarctic Division, studied tens of thousands of records of Antarctic species, collected over decades by hundreds of researchers, and found there are more species close to volcanoes, and fewer further away.

In end-stage lung disease, transplantation is sometimes the only viable therapeutic option, but organ availability is limited and rejection presents an additional challenge. Innovative research efforts in the field of tissue regeneration, including pioneering discoveries by University of Vermont (UVM) Professor of Medicine Daniel Weiss, M.D., Ph.D., and colleagues, holds promise for this population, which includes an estimated 12.7 million people with chronic obstructive pulmonary disorder (COPD), the third leading cause of death in the U.S.

Maintaining physical health brings a variety of benefits - including for the brain. A new study affirms that but also finds that lower IQ in teen years is correlated to a higher risk of dementia before the age of 60.

IQ doesn't really go up or down much so IQ at a young age isn't telling us much, but a study of one million young Swedish men included the data so it ended up being a factor.

  How did small bands of nomadic Mongol horsemen unite to conquer much of the world within a span of decades? A whole book could be written on that, and it probably will be, if a new "Indiana Jones" movie gets made using Genghis Khan.

The reasons are numerous and involve many different things but climate change is a less-considered one. Yet researchers studying the rings of ancient trees in mountainous central Mongolia say his conquest was likely due to nice weather. 

Research using satellite observations and ice thickness measurements gathered by NASA's Operation IceBridge is giving new insight into one of the processes causing Greenland's ice sheet to lose mass.

A team of scientists calculated the rate at which ice flows through Greenland's glaciers into the ocean, which gives a clearer picture of how glacier flow affects the Greenland Ice Sheet and shows that this dynamic process is dominated by a small number of glaciers.

Operation IceBridge has been measuring the thickness of many of Greenland's glaciers, which allowed researchers to make a more accurate calculation of ice discharge rates. Researchers calculated ice discharge rates for 178 Greenland glaciers more than one kilometer (0.62 miles) wide.

Aggressive marketing by raw milk proponents has included claims that raw milk is easier to stomach for for lactose-intolerant people but a pilot study from the Stanford University School of Medicine shows no meaningful difference in digestibility between raw and pasteurized milk.
