In contrast, high doses appear not to work, UCLA study suggests
An estimated 3 million Americans suffer from epileptic seizures. Although drug therapies often successfully dampen the out-of-control neural firing that produces seizures, such drugs don’t work for everyone. (more…)
Biotreibstoffe bieten eine Perspektive den CO2-Abdruck der Luftfahrt zu senken sowie mögliche ungünstige Klimaeinflüsse von Partikelemissionen und Kondensstreifen zu reduzieren. Diesem weltweit aktuellen Forschungsthema widmen sich die US-amerikanische Luft- und Raumfahrtbehörde NASA und das Deutsche Zentrum für Luft- und Raumfahrt (DLR) sowie das kanadische National Research Council (NRC) bei gemeinsamen Flugversuchen vom 7. bis 16. Mai 2014 in Kalifornien. In typischen Reiseflughöhen werden die Emissionen eines Biotreibstoff-Kerosin-Gemisches sowie dessen Auswirkungen auf die Bildung und Eigenschaften von Kondensstreifen vermessen. Die von der NASA geleitete Flugkampagne umfasst mehr als einhundert beteiligte Wissenschaftler und Techniker. Vier Forschungsflugzeuge sind im Einsatz, darunter die Falcon 20-E des DLR. Ausgangsort ist das Armstrong Flight Research Center der NASA am Standort Palmdale/Kalifornien. (more…)
Think pimples are something just teenagers get? If you say yes, then you are incorrect. More than 20 percent of women/men suffer from acne late into their twenties and thirties. Acne is an inflammatory skin condition, caused by the production of excess sebum, which clogs the pores and leads to pimples. Breakouts can occur all over the body, but are most commonly found on the face, back and chest. The cause could be anything from stress to hormonal fluctuation and more.
Over the counter products and antibiotics for clear skin are such a pain in terms of money and time. Many of them turn out to be harmful instead of being beneficial. So what is that harmless way to save us from acne breakouts and it’s after effects? (more…)
Baltimore, MD— One classical question in developmental biology is how different tissue types arise in the correct position of the developing embryo. While one signaling pathway that controls this process has been well described, unexpected findings from a team led by Carnegie’s Steven Farber reveal the importance of polyunsaturated fatty acid metabolism in this process. It is published online December 12 in Developmental Cell.
Fatty acids serve as sources of energy, the building materials of cellular membranes, and as signals for sending messages between cells. Enzymes are needed to activate free fatty acids so that they are useful for cellular processes. The enzymes that perform this function are called acyl-CoA synthetases, often shortened to ACS. (more…)
Investigation by researchers from the University of Exeter and ETH Zurich has shed new light on a protein which is linked to a common neurological disorder called Charcot-Marie-Tooth disease.
The team has discovered that a protein previously identified on mitochondria – the energy factories of the cell – is also found on the fat-metabolising organelles peroxisomes, suggesting a closer link between the two organelles.
Charcot-Marie-Tooth disease is currently incurable and affects around one in every 2,500 people in the UK, meaning that it is one of the most common inherited neurological disorders, thus understanding the molecular basis of the disease is of great importance. Symptoms can range from tremors and loss of touch sensation in the feet and legs to difficulties with breathing, swallowing, speaking, hearing and vision. (more…)
A team of academic researchers has pinpointed how vitamin D3 and omega-3 fatty acids may enhance the immune system’s ability to clear the brain of amyloid plaques, one of the hallmarks of Alzheimer’s disease.
In a small pilot study published in the Feb. 5 issue of the Journal of Alzheimer’s Disease, the scientists identified key genes and signaling networks regulated by vitamin D3 and the omega-3 fatty acid DHA (docosahexaenoic acid) that may help control inflammation and improve plaque clearance.

Berkeley Lab scientists join an international collaboration to understand how archaea and bacteria work together deep in a cold sulfur spring
In the fall of 2010, Hoi-Ying Holman of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) was approached by an international team researching a mysterious microbial community discovered deep in cold sulfur springs in southern Germany.
“They told me what they were doing and said, ‘We know what you contributed to the oil-spill research,’” recalls Holman, who heads the Chemical Ecology group in Berkeley Lab’s Earth Sciences Division. “They wondered if I could help them determine the biochemistry of their microbe samples.” (more…)
Eating more omega-3 fatty acids can offset damage, researchers say
