Researchers find how body’s good fat talks to the brain

by Dr. Jekyll in Lunatic Laboratories

There are two types of fat we humans have — white and brown — unfortunately only one of them is “good fat” and it is unfortunately not the one we tend to produce. Well new research shows that brown fat tissue, the body’s “good fat,” communicates with the brain through sensory nerves, possibly sharing information that is important for fighting human obesity, such as how much fat we have and how much fat we’ve lost....

Research on medical abortion/miscarriage may change international routines

by Dr. Jekyll in Lunatic Laboratories

Two scientific studies are expected to form the basis of new international recommendations for the treatment of medical abortions and miscarriages. One of the studies shows that it is possible to replace the clinical follow-up examinations recommended today with medical abortions that include a home pregnancy test. The other study shows that midwives can safely and effectively treat failed abortions and miscarriages in rural districts of Uganda.... Read more »

Music played by professionals activates genes for learning and memory

by Dr. Jekyll in Lunatic Laboratories

Music performance is known to induce structural and functional changes to the human brain and enhance cognition. However, the molecular mechanisms underlying music performance have been so far unexplored. A Finnish research group has now investigated the effect of music performance (in a 2 hr concert) on the gene expression profiles of professional musicians from Tapiola Sinfonietta (a professional orchestra) and Sibelius-Academy (a music university)....

Stereotype lowers math performance in women, no one noticed

by Dr. Jekyll in Lunatic Laboratories

Stereotypes about people can affect how we look at a person, but sometimes it causes other problems. Gender stereotypes about women’s ability in mathematics negatively impact their performance. And in a significant twist, both men and women wrongly believe those stereotypes will not undermine women’s math performance — but instead motivate them to perform better.... Read more »

High-fat diet causes brain inflammation and alters behavior

by Dr. Jekyll in Lunatic Laboratories

We hear in the media all the time, obesity is effecting our health. In most cases when we talk obesity we are talking about heart disease, sedentary activity, or chronic overeating. But what if a high-fat diet — regardless of obesity — has more than just an affect on your waistline? What if the consumption of fatty foods can change your behavior and your brain?... Read more »

Immunotherapy, a promising new treatment of Alzheimer’s disease

by Dr. Jekyll in Lunatic Laboratories

Alzheimer’s disease, it slowly takes things away from the person without giving anything back. Right now there is no cure and at best we can slow the progression in some cases. Time is always a factor and no two cases are the same. However, new treatments are in the works and a new study has revealed that a single dose of an immunotherapy reverses memory problems in an animal model of Alzheimer’s disease.... Read more »

Cracking the blood-brain barrier with magnetic nanoparticles

by Dr. Jekyll in Lunatic Laboratories

The blood-brain barrier, the thorn in the side of medicine. It makes using drugs directed for the brain ineffective at best and unusable at worst. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. This barrier means that currently 98% of therapeutic molecules are also unable to cross to the brain. However, researchers now say magnetic nanoparticles can open the blood-brain barrier and deliver molecules ........ Read more »

The cool car: electric vehicles show possible benefit to combat climate change

by Jonathan Trinastic in Goodnight Earth

Electric vehicles are touted as environmentally friendly, but they actually pollute more than conventional vehicles during manufacturing. However, a new report argues that, because electric vehicles are cooler, they can reduce heat and temperature increases in urban environments, leading to a net reduction in greenhouse gas emissions....

FDA struggles to define what “natural” means for food labels

by Dr. Jekyll in Lunatic Laboratories

After decades of debate there remains no generally accepted definition of a “natural” food product. Despite a gamut of products with the label prominently displayed, it has caused a headache in lawsuits for the government who have yet to define “natural”. According to new research, while regulatory agencies have refused to settle the issue, they may be under new pressure from those consumer lawsuits.... Read more »

Milk, not just for your bones, for your brain

by Dr. Jekyll in Lunatic Laboratories

Milk, depending on who you ask it’s either great or the devil. In the US drinking milk is common; not so much in other parts of the world. This has lead to questions about why we even drink milk and how real its reported health claims actually are. Well new research has found a correlation between milk consumption and the levels of a naturally-occurring antioxidant called glutathione in the brain in older, healthy adults.... Read more »

The neurological basis for anorexia nervosa

by Dr. Jekyll in Lunatic Laboratories

Most of us know about dieting, and if not first hand, have seen in the news or from friends how hard sticking to a diet long-term can be. This is because adults (regardless of their weight_ resolve to lose weight. Yet, more often than not, that chocolate lava cake is too enticing and that resolve vanishes. This behavior is normal because hunger increases the intensity of food rewards. Yet, individuals with anorexia nervosa (AN), despite their state of starvation, are able to ignore such food-rel........ Read more »

Komodo Dragons: Their Bite is Worse than Their Bark

by Miss Behavior in The Scorpion and the Frog

By Shelly Sonsalla Komodo Dragon. Image by Arturo de Frias Marques on Wikimedia. Komodo dragons are the world’s largest living lizard and can be found only on select islands in the Indonesian archipelago. These massive lizards can grow to be 10 feet in length and up to 150 pounds! Their natural prey includes wild boars, deer, and water buffalo—animals which may outweigh them by several hundred pounds. So how does a lizard, even such a large one, manage to take down prey so much larger tha........ Read more »

Special microbes make anti-obesity molecule in the gut

by Dr. Jekyll in Lunatic Laboratories

You’ve probably heard of all sorts of diets, paleo, low-fat, low-carb, atkins, but now microbes may just be the next diet craze. Researchers have programmed bacteria to generate a molecule that, through normal metabolism, becomes a hunger-suppressing lipid (fat). Mice that drank water laced with the programmed bacteria ate less, had lower body fat and staved off diabetes — even when fed a high-fat diet — offering a potential weight-loss strategy for humans....

Squid prolifically edit RNA to enrich their DNA

by Dr. Jekyll in Lunatic Laboratories

DNA, it’s what makes us, well us! Not that long ago, before we sequenced human DNA we assumed we had one of the largest genomes around. Frankly it wasn’t a bad assumption, but of course we found out this was far from the case and to make ourselves feel better we said size doesn’t matter. But one of the surprising discoveries to emerge from comparative genomics is that drastically different organisms–humans, sea urchins, worms, flies –are endowed with a more or less common set of genes.........

The impact of military deployment on children

by Dr. Jekyll in Lunatic Laboratories

Being a military family is hard, it’s hard for the person serving (obviously) and if divorce rates are any indication, it is also hard on the spouse. While the added stress of deployment on a family cannot adequately be explained, even as someone who has seen it first hand, those stresses affect even the littlest members of the family. A new study reports that following military parents’ return from combat deployment, their children show increased visits for mental healthcare, physical injur........ Read more »

Not “just in your head,” brain networks differ among those with severe schizophrenia

by Dr. Jekyll in Lunatic Laboratories

The brain is plastic, it’s how we grow, it’s how we adapt, it is quite literally how we survive. This can unfortunately be to our detriment and new research shows that people with a severe form of schizophrenia have major differences in their brain networks compared to others with schizophrenia, bipolar disorder and healthy individuals. So while it may be true, that it is all be in your head, it isn’t how people usually mean it.... Read more »

Is diet soda making you fat?

by Dr. Jekyll in Lunatic Laboratories

The diet soda controversy is still raging on, study after study has been coming in saying that it helps weight loss, it hurts weight loss, and frankly it can all be a little confusing. Well this probably won’t help matters any, a new study shows that increasing diet soda intake is directly linked to greater abdominal obesity in adults 65 years of age and older. These findings raise concerns about the safety of chronic diet soda consumption, which may increase belly fat and contribute to greate........ Read more »
