A population explosion of golden algae, a fast-growing invasive plant, has killed thousands of threadfin shad and some gizzard shad at Apache Lake, a reservoir in central Arizona.

When co-discovers Gary Tenen and Randy Tufts found the blowhole entrance to the caverns in 1974, they did something extraordinary: They kept it a secret. And when they could no longer shield the caves through secrecy, they sought out science to help protect Kartchner Caverns post-development.
Research has supported Kartchner ever since, but the reverse is true as well. Read/listen to my full story at KJZZ’s Arizona Science Desk to find out how:
At Arizona’s Kartchner Caverns, Science Supports Stewardship — And Vice Versa
The book The Runner’s Brain told runners how their minds could change their running. Now a University of Arizona study says the reverse might be true as well.
Using functional connectivity MRI (fcMRI), they found significant differences in areas that are active when the brain is at rest. Possibly, such networks could play a key role in the effects of aging and neurodegenerative diseases.

Arizona Study: Brains Of Young Adult Runners Differ From Those Of Healthy Peers
Yep, after decades of false starts, it is now possible – for the few, the young and the obsessive – to make a living playing video games. Sprung from LAN party tournaments played for beer money stakes, eSports has today evolved into full-blown sporting franchise, complete with teams, groupies, college athletic programs, dedicated media, arena-filling crowds and tournament prize pools ballooning into the tens of millions of dollars.
For many, this development raises a number of questions. Are these really athletes? (Hint: the U.S. government thinks so.) Why was Amazon willing to pay almost a billion dollars for Twitch.tv? And, well, just how does professional gaming work?
No one can say when people first started throwing knives, but I’m willing to bet that it was the result of boredom, desperation or an ill-thought-out dare. How we got from there to the Wheel of Death involves a journey from Africa, through the Wild West shows and circuses of the 1800s, and finally to our own backyards.
Knives hardly sail through the air like arrows, but throwing them is not a difficult as it might seem. So grab your weapon of choice and join me as I explain …
