Brown fat is a type of body fat that is full of the darker "energy factories of cells" called mitochondria. Mitochondria feed on calories - lots of them - which are then turned into energy and heat, according to&nbsp;.&nbsp;"Baby fat" is actually brown fat, which is why newborns get chilly so quickly and need to be kept wrapped up. As we get older, we get better at regulating our temperature in part because we lose most of the heat-throwing brown fat.<br>

"Pretty much everything in our rivers and lakes is directly or indirectly vulnerable," said Dr David Aldridge, co-author from the University of Cambridge's Department of Zoology, who confirmed the quagga find only two weeks ago.

So, how do we turn our white fat into brown fat? Researchers at Yale School of Medicine have figured it out by studying the energy expenditure, eating habits and weight of mice.<br>

These ominous shrimps, dubbed the demon shrimp, bloody red shrimp, and pink peril, could act as gateway species to allow others in by allowing for favorable inter-species interactions such as food provision.<br>
  
Have you ever heard that lowering your calories to too low of a level can stop weight loss? That's because it's true. Fasting can cause the body to shut down and only use energy for vital life functions, like heart and lung functions. Evolutionarily, this makes sense. If your body thinks you're facing famine, it tries to save itself. When the mice needed extra emergency energy, brown fat provided quick bursts of energy.<br>

An example is the zebra mussel (a relative of the quagga), which has been seen in Britain since 1824 and smothers native species so they cannot move. These mussels allow invasive shrimp to thrive because they can more easily camouflage into their striped shells. The shrimp, in turn, provide food for the invasive Ponto-Caspian gobie fish that have made their way down the Rhine. The presence of these non-native fish is problematic because they eat and displace native species.<br>
  
Associate Professor at Yale, Xiaoyong Yang, said this switch between energy has to do with the relationship between hunger signals and the brain, according to Time.<br>

"If we look at The Netherlands nowadays it is sometimes hard to find a non-Ponto-Caspian species in their waterways," Aldridge said. "In some parts of Britain the freshwater community already looks more like the Caspian Sea. The Norfolk Broads, for example, typically viewed as a wildlife haven, is actually dominated by Ponto-Caspian zebra mussels and killer shrimps in many places."<br>
  
"We showed that hunger itself is a signal that controls the browning of white fat, so the brain can actually control the browning of white fat," Yang said.&nbsp;"Obese animals, and people, lose the response to hunger. Although there is plenty of food and plenty of energy, the hunger neurons send a false message that the body needs to conserve energy, not burn it."<br>
+
In a study published Oct. 12 in the Journal of Applied Ecology the researchers identified the 23 most high-risk invasive Ponto-Caspian species.<br>
  
The trick is to change the hunger signal so it tells the brain to burn fat instead of storing it. Obese mice ate whether they were hungry or not, so the brain and stomach couldn't communicate properly. Signals got ignored.<br>

"Due to globalisation and increased travel and freight transport, the rate of colonisation of invasive species into Britain from The Netherlands keeps accelerating - posing a serious threat to the conservation of British aquatic ecosystems," said co-author Dr Belinda Gallardo, now based at the Do ana Biological Station in Spain.

Plumper animals feel hungry all the time, so the brain shuts down energy expenditure to famine levels. So, you...or rather, the mice... feel hungry constantly and eat continuously while your body thinks you are starving.<br>

@@@ "Pretty much everything in our rivers and lakes is directly or indirectly vulnerable," said Dr David Aldridge, co-author from the University of Cambridge's Department of Zoology, who confirmed the quagga find only two weeks ago. "The invader we are most concerned about is the quagga mussel, which alarmingly was first discovered in the U.K. just two weeks ago. This pest will smother and kill our native mussels, block water pipes and foul boat hulls. We are also really worried about Ponto-Caspian shrimps, which will eat our native shrimps."

These ominous shrimps, dubbed the demon shrimp, bloody red shrimp, and pink peril, could act as gateway species to allow others in by allowing for favorable inter-species interactions such as food provision.

An example is the zebra mussel (a relative of the quagga), which has been seen in Britain since 1824 and smothers native species so they cannot move. These mussels allow invasive shrimp to thrive because they can more easily camouflage into their striped shells. The shrimp, in turn, provide food for the invasive Ponto-Caspian gobie fish that have made their way down the Rhine. The presence of these non-native fish is problematic because they eat and displace native species.

"If we look at The Netherlands nowadays it is sometimes hard to find a non-Ponto-Caspian species in their waterways," Aldridge said. "In some parts of Britain the freshwater community already looks more like the Caspian Sea. The Norfolk Broads, for example, typically viewed as a wildlife haven, is actually dominated by Ponto-Caspian zebra mussels and killer shrimps in many places."

In a study published Oct. 12 in the Journal of Applied Ecology the researchers identified the 23 most high-risk invasive Ponto-Caspian species.

"Cross-country sharing of information on the status and impacts of invasive species is fundamental to early detection, so that risks can be rapidly assessed. A continuing process for evaluating invasive species and detecting new introductions needs to be established, as this problem is increasing dramatically."
