Farmed Salmon = Most Toxic Food in the World
Posted by Fyodor Rouge in categories: biotech/medical, food, health, sustainability
Fish are an important part of the ecosystem and the human diet. Unfortunately, overfishing has depleted many fish stocks, and the proposed solution — fish farming — is creating far more problems than it solves. Not only are fish farms polluting the aquatic environment and spreading disease to wild fish, farmed fish are also an inferior food source, in part by providing fewer healthy nutrients; and in part by containing more toxins, which readily accumulate in fat.
Farmed Salmon = Most Toxic Food in the World
Salmon is perhaps the most prominent example of how fish farming has led us astray. Food testing reveals farmed salmon is one of the most toxic foods in the world, having more in common with junk food than health food. Studies highlighting the seriousness of the problem include:

Anti-Alzheimer’s Protein Complex Identified
Posted by Steve Hill in categories: biotech/medical, life extension, neuroscience
A new mouse study highlights the proteins responsible for LC3-associated endocytosis (LANDO), an autophagy process that is involved in degrading β-amyloid, the principal substance associated with Alzheimer’s disease.
Proteostasis
Proteins in the human brain can form misfolded, non-functional, and toxic clumps known as aggregates. Preventing these aggregates from forming, and removing them when they do, is a natural function of the human body, and it is known as proteostasis. However, as we age, this function degrades, and loss of proteostasis is one of the hallmarks of aging. The resulting accumulation of aggregates leads to several deadly diseases, one of which is Alzheimer’s.

Couple clones cat after it dies for hefty price
Posted by Heather Blevins in category: biotech/medical
HUNTERSVILLE, N.C. (WCNC) – A North Carolina couple couldn’t bear to break the bond they had with their furry feline friend. So after 19-year-old Cinnabun passed away, the Bullerdicks decided to clone their kitty.
The cost? A whopping price of $25,000.
The couple found a Texas-based company known for cloning dogs, cats and horses. They bought a kit and with a skin sample and saliva sample… Cinnabun the second was born.

New blood test for detecting Alzheimer’s disease
Posted by Paul Battista in categories: biotech/medical, neuroscience
Researchers from Lund University, together with the Roche pharmaceutical company, have developed a method to create a new blood marker capable of detecting whether or not a person has Alzheimer’s disease. If the method is approved for clinical use, the researchers hope eventually to see it used as a diagnostic tool in primary healthcare. This autumn, they will start a trial in primary healthcare to test the technique.
Currently, a major support in the diagnostics of Alzheimer’s disease is the identification of abnormal accumulation of the substance beta-amyloid, which can be detected either in a spinal fluid sample or through brain imaging using a PET scanner.
“These are expensive methods that are only available in specialist healthcare. In research, we have therefore long been searching for simpler diagnostic tools,” says Sebastian Palmqvist, associate professor at the unit for clinical memory research at Lund University, physician at Skåne University Hospital and lead author of the study.
