Those extra pounds around your belly that no amount of exercise seems to shake off? That's not just fat; it's what scientists call white fat – unhealthy, energy-storing fat.

Brown fat, however, has been known to contain energy-burning, heat-producing qualities that could be key to helping people lose weight. The key is finding a way to increase brown fat in the body and reduce the white fat.

Hibernating mammals have brown fat, and human babies are born with it to help them keep warm outside the womb. Adults also have varying amounts of brown fat, but researchers weren't sure if it’s the same kind babies are born with, and if not, where it comes from.

Three kinds of whale, six varieties of seal, the walrus and the polar bear all have these five things in common: they are marine mammals; they depend on the Arctic for their survival as species; they are vulnerable; and biologists know surprisingly little about them. And since the Arctic is warming twice as fast as the rest of the planet, their future could become even more threatened as climate change increases habitat loss.

Soil, long thought to be a semi-permanent storehouse for ancient carbon, may be releasing carbon dioxide to the atmosphere faster than anyone thought, according to Oregon State University soil scientists. In a study published in this week’s online edition of the journal Nature Climate Change, the researchers showed that chemicals emitted by plant roots act on carbon that is bonded to minerals in the soil, breaking the bonds and exposing previously protected carbon to decomposition by microbes.

The threat of deforestation is understood as one of the major problems in the world today, but a new study suggests that the total amount of vegetation in the world appears to have increased in the past decade, suggesting a rare ray of light in conservation and climate change news.

The study, which was published late last month in the journal Nature Climate Change, saw researchers from Australia assess the amount of carbon stored in living plant mass, also known as biomass, stored above ground. This is one established way that we can measure not just how much carbon is stored but also the density of biomass in any given area and so provides us with an interesting way of assessing regional and global forest densities.

Maryland crab cakes are as important to Baltimore’s heritage as Hairspray, the Star Spangled Banner and Orioles baseball. In fact, many would say a visit to Maryland would be lacking without sampling them, whether you are vacationing on the Eastern Shore or in the DC area for a business meeting. Restaurants such as Phillips Seafood, Obryckis and Faidley’s have built an enduring business thanks to this local specialty. However, according to a new study almost 40 percent of crab cakes tested in a survey revealed DNA evidence of fraud in the crab industry.
