I've been interested in the edible forest garden idea for over twenty years and have planted and designed several myself in Ireland in that time, and visited several others. But they have never lived up to my expectations and were largely unproductive, despite sourcing as many perennial vegetables and other interesting edible plants as I could. Here I review the claims made for them and what evidence there is to support the idea- and conclude that, as Permaculture founder Bill Mollison said in the first place, in temperate regions you are far better growing your fruit trees and vegetables separately.

Book review: The New Wild: Why invasive species will be nature's salvation by Fred Pearce

In 1910  New Zealand's great botanist Leonard Cochayne described the dramatic change in  plant communities which had occurred since the first visit of Captain Cook to the country in 1769 (1). Some 560 new species from Europe, Africa and elsewhere had by become established by then, with half of them common throughout the country from the coasts to the highest mountains:

INDIANAPOLIS -- Using stem cells derived from human skin cells, researchers led by Jason Meyer, assistant professor of biology, along with graduate student Sarah Ohlemacher of the School of Science at Indiana University-Purdue University Indianapolis, have successfully demonstrated the ability to turn stem cells into retinal ganglion cells (RGCs), the neurons that conduct visual information from the eye to the brain. Their goal is the development of therapies to prevent or cure glaucoma.

In addition to glaucoma, a group of degenerative diseases that damage the eye's optic nerve and can result in vision loss and blindness, this work has potential implications for treatment of optic- nerve injuries of the types incurred by soldiers in combat or athletes in contact sports.

I am very happy to report that Professor Giorgio Parisi won another prize. Parisi is an Italian theoretical physicist who is very well known for his decisive contribution to QCD, with the DGLAP equations (the P stands for his last name) that govern the dynamics of gluons. However his work did not stop there - after that result Parisi continued excellent research and it is not by chance that he collected prizes and acknowledgements along the way for the more recent contributions he has given to theoretical physics.

For Pi Day 2016, I’ll demonstrate how to flash a Snap Circuits LED with the Kano Computer (my version of the Kano has the Raspberry Pi 2). I've lost count of how many computers I've built over the years, but I think it is safe to say that the Kano Computer was the easiest build ever. So simple a child could do it. Kano founders, Yonatan Raz-Fridman, Alex Klein, and Saul Klein, wanted to figure out what the next generation’s computer would be like, so they asked Micah, Saul’s seven-year-old son.
Deputy Attorney General, Sally Yates, made what might be considered a historic announcement at the recent annual gathering of the American Academy of Forensic Sciences in Las Vegas, Nevada.  

Summarizing the results of a multi-disciplinary review of forensic hair tests conducted by the FBI laboratory over many years, Yates claimed that 90% of those reviews showed evidence that FBI scientists erred during their court testimony - that perhaps FBI representatives overstated the significance of their findings or suggested that the forensic results were more incriminating than they actually were.

Back in January, Bradley Schaefer published a finding that promised to be a bombshell: KIC 8462852 had been dimming at a rate of nearly 20% per century since 1890 (Schaefer, 2016). The finding was widely reported as refutation of the comet family hypothesis, and further evidence that KIC 8462852 might be home to a Type 2 alien civilization.
