Research shows mice brains are 'very wired up' at birth, suggests experience selects which connections to keep
Ask the average person the street how the brain develops, and they'll likely tell you that the brain's wiring is built as newborns first begin to experience the world. With more experience, those connections are strengthened, ...

Saturated fatty acids lead to mitochondrial dysfunction and insulin resistance
Excessive levels of certain saturated fatty acids cause mitochondria to fragment, leading to insulin resistance in skeletal muscle, a precursor of type 2 diabetes, according to a paper in the January issue of the journal ...

Cold viruses point the way to new cancer therapies
Cold viruses generally get a bad rap—which they've certainly earned—but new findings by a team of scientists at the Salk Institute for Biological Studies suggest that these viruses might also be a valuable ...

Eat too much? Maybe it's in the blood
Bone marrow cells that produce brain-derived eurotrophic factor (BDNF), known to affect regulation of food intake, travel to part of the hypothalamus in the brain where they "fine-tune" appetite, said researchers from Baylor ...

Low-dose naltrexone (LDN): Tricking the body to heal itself
Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered the mechanism by which a low dose of the opioid antagonist naltrexone (LDN), an agent used clinically (off-label) ...

Live longer with fewer calories
By consuming fewer calories, ageing can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers ...

Sending out an SOS: How telomeres incriminate cells that can't divide
The well-being of living cells requires specialized squads of proteins that maintain order. Degraders chew up worn-out proteins, recyclers wrap up damaged organelles, and-most importantly-DNA repair crews ...

Fatheads: How neurons protect themselves against excess fat
We're all fatheads. That is, our brain cells are packed with fat molecules, more of them than almost any other cell type. Still, if the brain cells' fat content gets too high, they'll be in trouble. In a recent study in mice, ...

Researchers identify and block protein that interferes with appetite-suppressing hormone
Ever since the appetite-regulation hormone called leptin was discovered in 1994, scientists have sought to understand the mechanisms that control its action. It was known that leptin was made by fat cells, reduced appetite ...
