Neuroscientists Can Now Read Your Dreams With a Simple Brain Scan
Posted by Shailesh Prasad in category: neuroscience
Like islands jutting out of a smooth ocean surface, dreams puncture our sleep with disjointed episodes of consciousness. How states of awareness emerge from a sleeping brain has long baffled scientists and philosophers alike.
For decades, scientists have associated dreaming with rapid eye movement (REM) sleep, a sleep stage in which the resting brain paradoxically generates high-frequency brain waves that closely resemble those of when we’re awake.
Yet dreaming isn’t exclusive to REM sleep. A series of oddball reports also found signs of dreaming during non-REM deep sleep, when the brain is dominated by slow-wave activity—the opposite of an alert, active, conscious brain.

Amino acids in diet could be key to starving cancer
Posted by Steve Hill in category: biotech/medical
Starving cancer via amino acids looks like a promising approach.
Cutting out certain amino acids — the building blocks of proteins — from the diet of mice slows tumor growth and prolongs survival, according to new research published in Nature.
Researchers at the Cancer Research UK Beatson Institute and the University of Glasgow found that removing two non-essential amino acids — serine and glycine — from the diet of mice slowed the development of lymphoma and intestinal cancer.

Experts excited by brain ‘wonder-drug’
Posted by Dan Kummer in categories: biotech/medical, neuroscience
Scientists hope they have found a drug to stop all neurodegenerative brain diseases, including dementia. In 2013, a UK Medical Research Council team stopped brain cells dying in an animal for the first time, creating headline news around the world. But the compound used was unsuitable for people, as it caused organ damage. Now two drugs have been found that should have the same protective effect on the brain and are already safely used in people. “It’s really exciting,” said Prof Giovanna Mallucci, from the MRC Toxicology Unit in Leicester. She wants to start human clinical trials on dementia patients soon and expects to know whether the drugs work within two to three years.
Why might they work?
The novel approach is focused on the natural defence mechanisms built into brain cells.
