Photosynthesis - The Last Link In The Chain
2013-01-05 05:45:05

April Flowers for redOrbit.com - Your Universe Online For almost three decades, scientists have tried to identify a particular enzyme involved in regulating electron transport during photosynthesis. Now, a research team from Ludwig Maximilians Universitat (LMU) has found the missing link, which turns out to be not so new. All life on Earth is sustained by photosynthesis, a sunlight powered process that provides energy-rich compounds and the molecular oxygen that higher organisms depend...

Scientists from VIB and KU Leuven have discovered a new target molecule for the development of a treatment against Alzheimer's disease. There is currently no cure for this disease. Many candidate drugs fail because they also target proteins essential to life. This discovery from Leuven could form a target for a treatment against Alzheimer's disease with fewer side effects and that suppresses the very first symptoms of the disease. This research will be published in the leading journal Nature...

Alzheimer's disease is one of the most common causes of dementia. In Germany and Switzerland alone, around 1.5 million people are affected, and forecasts predict a doubling of the number of patients worldwide within the next 20 years. The accumulation of particular abnormal proteins, including amyloid-ß (Aβ) among others, in patients' brains plays a central role in this disease. Prof. Frank Heppner from the Department of Neuropathology at Charité and his...

Mouse model may provide clues on mechanism linking diabetes and aging to Alzheimer's Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. In a new study published in Aging Cell, researchers at the Salk Institute for Biological Studies show, for the first time, that diabetes enhances the development of aging features that may underlie...

Researchers at Washington University School of Medicine in St. Louis have found a key difference in the brains of people with Alzheimer's disease and those who are cognitively normal but still have brain plaques that characterize this type of dementia. "There is a very interesting group of people whose thinking and memory are normal, even late in life, yet their brains are full of amyloid beta plaques that appear to be identical to what's seen in Alzheimer's disease," says David L. Brody,...

Chemists at the California Institute of Technology (Caltech) have managed, for the first time, to simulate the biological function of a channel called the Sec translocon, which allows specific proteins to pass through membranes. The feat required bridging timescales from the realm of nanoseconds all the way up to full minutes, exceeding the scope of earlier simulation efforts by more than six orders of magnitude. The result is a detailed molecular understanding of how the translocon works....


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
