A team of scientists have shown that meltwater from the surface of an ice cap in northeastern Greenland can make its way beneath the ice and become trapped, refilling a subglacial lake. This meltwater provides heat to the bottom of the ice sheet.

The findings provide new information about atmospheric warming and its affect on the critical zone at the base of the ice. The warmth provided by the water could make the ice sheet move faster and alter how it responds to the changing climate.

Two new drug compounds - one of which has already proven useful in a mouse model of multiple sclerosis - appear to be effective in treating endometriosis, a disorder that, like MS, is driven by estrogen and inflammation, scientists report in Science Translational Medicine.

The researchers hope to eventually use the new compounds and others like them to treat a variety of disorders linked to estrogen signaling and inflammation: endometriosis, multiple sclerosis, inflammatory breast cancer, liver fibrosis, and cardiovascular and metabolic problems associated with obesity, for example.

People are more successful in taking up healthy habits if their partner makes positive changes too, according to research* published in JAMA Internal Medicine today (Monday).

Scientists at UCL funded by Cancer Research UK, the British Heart Foundation, and the National Institute on Aging looked at how likely people were to quit smoking, start being active, or lose weight in relation to what their partner did.**

They found that people were more successful in swapping bad habits for good ones if their partner made a change as well.

Carbon sequestration promises to address greenhouse-gas emissions by capturing carbon dioxide from the atmosphere and injecting it deep below the Earth's surface, where it would permanently solidify into rock. The U.S. Environmental Protection Agency estimates that current carbon-sequestration technologies may eliminate up to 90 percent of carbon dioxide emissions from coal-fired power plants.

While such technologies may successfully remove greenhouse gases from the atmosphere, researchers in the Department of Earth, Atmospheric and Planetary Sciences at MIT have found that once injected into the ground, less carbon dioxide is converted to rock than previously imagined.

Consumers usually look for the lowest price when shopping for a product. But can prices sometimes just feel right? According to a new study in the Journal of Consumer Research, consumers are drawn to prices with rounded numbers when a purchase is motivated by feelings.

"A rounded price ($100.00) encourages consumers to rely on feelings when evaluating products, while a non-rounded price ($98.76) encourages consumers to rely on reason. When a purchase is driven by feelings, rounded prices lead to a subjective experience of feeling right," write authors Monica Wadhwa (INSEAD, Singapore) and Kuangjie Zhang (Nanyang Technological University).
