TLX gene stimulates growth of new brain cells in adults, leading to faster learning in the animal model

TLX gene stimulates growth of new brain cells in adults, leading to faster learning in the animal model | Jeff Morris | Scoop.it

Over-expressing a specific gene could prompt growth in adults of new neurons in the hippocampus, where learning and memory are regulated, City of Hope researchers have found.

 

The study, which used an animal model, found that over-expression of the TLX gene resulted in smart, faster learners that retained information better and longer.

 

Understanding the link between this gene and the growth of new neurons — or neurogenesis — is an important step in developing therapies to address impaired learning and memory associated with neurodegenerative diseases and aging.

 

The new research was published June 9 in the Proceedings of the National Academy of Sciences.

 

“Memory loss is a major health problem, both in diseases like Alzheimer’s, but also just associated with aging,”said Yanhong Shi, Ph.D., lead author of the study and a neurosciences professor at City of Hope.

 

“In our study, we manipulated the expression of this receptor by introducing an additional copy of the gene — which obviously we cannot do outside the laboratory setting. The next step is to find the drug that can target this same gene.”

 

Researchers found that over-expression of the gene was actually associated with a physically larger brain, as well as the ability to learn a task quickly. Furthermore, over-expression of the gene was linked with the ability to remember, over a longer period of time, what had been learned.

 

The discovery creates a new potential strategy for improving cognitive performance in elderly patients and those who have a neurological disease or brain injury.

 

The bulk of the brain’s development happens before birth, and there are periods — largely in childhood and young adulthood — when the brain experiences bursts of new growth. In the past couple of decades, however, scientists have found evidence of neurogenesis in later adulthood — occurring mostly in the hippocampus, the region of the brain associated with learning and memory.

Making hydrogen fuel from water and visible light at 100 times higher efficiency

Making hydrogen fuel from water and visible light at 100 times higher efficiency | Jeff Morris | Scoop.it

A big step closer to hydrogen as a practical fuel to power vehicles and electrical devices.


Researchers at Michigan Technological University have found a way to convert light to hydrogen fuel more efficiently — a big step closer to mimicking photosynthesis. Current methods for creating hydrogen fuel are based on using electrodes made from titanium dioxide (TiO2), which acts as a catalyst to stimulate the light–>water–>hydrogen chemical reaction. This works great with ultraviolet (UV) light, but UV comprises only about 4% of the total solar energy, making the overall process highly inefficient.*


The ideal would be to use visible light, since it constitutes about 45 percent of solar energy. Now two Michigan Tech scientists — Yun Hang Hu, the Charles and Carroll McArthur professor of Materials Science and Engineer, and his PhD student, Bing Han — have developed a way to do exactly that.


They report in Journal of Physical Chemistry that by absorbing the entire visible light spectrum, they have increased the yield and energy efficiency of creating hydrogen fuel by up to two magnitudes (100 times) greater than previously reported.

Infected ad networks hit popular websites

Infected ad networks hit popular websites | Jeff Morris | Scoop.it

It is frustrating when your antivirus protection  stops you (pray it does) from visiting a website that you know and trust, but these days even the most popular websites can fall prey to attacks.

This week security researchers discovered booby-trapped advertisements on popular websites including eBay, The Drudge Report, weather.com, and AOL. The ads, some of which can be initiated by a drive-by attack without the user’s knowledge or even any action, infected computers with adware or locked them down with ransomware.

Computer users running older browsers or unpatched software are more likely to get infected with malware just by visiting a website.
