Not surprisingly, cities tend to be very noisy, with background levels averaging around 50 to 60 decibels. And that’s just the average: heavy truck traffic can reach around 85 dB, while construction jackhammers can reach 95 dB if you’re standing less than 50 feet away.
By contrast, regions like Yellowstone National Park have background noise levels down at around 20 decibels, which, as Underwood reports, is about as hushed as things were before European colonization.
So who cares? For one, all the artificial noise and light that cities produce can have bizarre effects on humans and wildlife — effects we have yet to fully understand. Loud cities can interfere with the ability of owls and bats to hunt. And, because of urban noise, some male birds now have to sing at higher frequencies, making them less attractive to potential mates.

In this installment of the Free Radical Media podcast, hosts Eric Scott Pickard and Patrick Ryan are joined by their friend and former guest, Dan DeLion. DeLion, herbalist, forager, naturalist and teacher is the founder of the organization Return to Nature. This time around, Dan discusses his new, far-ranging documentary project, “Hunting the Medicine: Stalking the Wild Spirit,” which has taken him to such places as Columbia and India. He also details his recent personal experience with Ayahuasca in a Shamanic setting, and shares his views and insight into the world of herbalism and the philosophy of living in harmony with the natural world.

Often considered the smartest invertebrates (animals without backbones) on the planet, octopuses can use tools, unscrew jar lids and tightly control their body color to match their surroundings. They use this sharp intelligence especially in situations of survival — including when they are trying to avoid getting eaten by their hungry mates.
Octopuses come in all shapes and sizes and inhabit diverse regions of the ocean. There are about 100 different species of octopuses in the genus Octopus, and at least another 150 species in other genera, said Jennifer Mather, a cephalopod expert at the University of Lethbridge in Canada. Scientists have witnessed the mating behavior of only about a dozen species, she added.
The marine animals have very short lives, generally lasting only a few years long and sometimes as short as 6 months. They spend their youth alone, eating and growing before reaching sexual maturity.
In this episode of the Free Radical Media podcast, herbalist Susun Weed joins the crew to discuss the methods and philosophy of natural healing. The leading voice in the Wise Woman tradition of healing, Susun Weed is the author of the Wise Woman Herbalist series of books as well as an educator and lecturer. She discusses the “Three Traditions of Healing,” the philosophy of natural and “wholeistic” medicine, and the usefullness of herbal supplements in this lively episode.

Who needs Science Fiction, when we have this?
We finally managed to video the first Xenesthis sp White while it was molting. It took a total of 10 hours to complete. Fortunately for the viewers the tarantula actually molted up-right allowing me to capture a very detailed carapace. Seems like this is the first video of this species so enjoy.

So, what the hell is happening here? Luckily IFL Science has the answer:
Ice shoves occur when strong winds or currents force the ice from the water’s surface to go on land. These events are also called “ice tsunamis” because of the way they come on land, but ice shoves are closer to icebergs than tsunamis in how they work.
The force from the ice shove can be powerful enough to knock over trees, houses, and docks that stand in its way.

In 1989, ‘acoustic ecologist’ Gordon Hempton received a grant to document and record the natural sounds of the state of Washington in the USA. He identified 21 wilderness places to record—sites unsullied by the sounds of traffic, aviation, construction, and other human-made noise. Twenty-five years later, only three of those sites remain muted.
Little by little, our world is becoming louder, with the creeping spread of noise pollution infiltrating our homes, our workplaces, and even our wilderness.
Hempton, whose work for the past 30 years has been traveling the world to survey and record natural sound, says he’s seen firsthand how the hum, ping, and roar of modern life has taken over our sound-scapes. By his count, the United States has only 12 remaining truly ‘quiet places,’ which he defines as somewhere you can go for at least 15 minutes without hearing artificial sound at dawn, the hour when sound travels farthest.
“In the first half of the 20th century, the prevailing idea was that humans could be masters of nature and the universe. We thought that human power was unlimited. We thought- ‘we can change rivers, we can move mountains,’ we can actually conquer nature. Then sometime in the second half of the 20th century, we made the realization that the relationship between nature and humans is actually much more complex than that.” -Dr. Michael Nosonovsky.
If you love technology, congratulations! You’re living in what is, without a doubt, the most exciting time for it in human history. We’ve got self-driving cars, Oculus Rift, ubiquitous pocket-dwelling supercomputers and giant televisions in nearly every home. It’s almost enough to make you forget about ISIS, Ebola, killer asteroids and climate disaster.
So let’s dampen the fear mongering feedback loop a bit further by jumping the technological brainwashing (I use that phrase with great affection) up a few notches.… Read the rest
Nature is aglow with such a variety of bioluminescent life forms it makes me want to lie down and be covered with fungi and fireflies!
Drones have it kind of tough nowadays. Not only do people think drones flying around are annoying (or worse), camera-toting remote-controlled gizmos often find themselves attacked by planes, sharks and, now, hawks.
The drone in the above video, owned by Christopher Schmidt, is just minding its business flying around the skies above Magazine Beach Park in Cambridge, Mass., when a hawk seemingly comes out of nowhere and, in one fell swoop, throws the drone to the ground.
The hawk, a natural predator, likely thought the drone was invading its turf, and, according to Schmidt’s report, happily retreated after defeating its prey. Fortunately, both the hawk and the drone came away from the brief scuttle unscathed.
