Ka-Pow: Watch These Fish Cannons Shoot Salmon Safely Over Dams

Salmon have serious swimming skills—some travel thousands of miles to return to their original homes to breed. But even though they can jump as high as 12 feet in the air, they can’t manage to get over massive concrete dams that we have built to block their journeys back to their homes. Now one new idea could give them a boost. The plan involves whisking the fish through a long vacuum tube at speeds up to 22 miles per hour and then shooting them out the other end like a cannon.

When lizards are caught by predators, they can drop their tails to escape and then grow the appendage back. Scientists have studied this regeneration process for decades, in the hopes of understanding how to regenerate human tissues, such as damaged spinal chords and even lost limbs.
Now a team of scientists from Arizona State University in the US has performed the first analysis of all RNA molecules, which translate genes into proteins, during the tail regeneration of a green anole lizard (Anolis carolinensis), and worked out the genetic “recipe” that controls the regrowth process. Their results have been published in PLOS ONE.

Humans Need Not Apply

A colleague sent me this video yesterday. Probably the most sober dip into the future of technology I’ve seen yet. Perhaps I am a minority, but I do see rising inequality and the difficulty of our current economic moment as heavily impacted and sustained by the rapid pace of technological advancement (and subsequently the value that technology creates being consolidated in the hands of very few).

All of this is a good thing… if our social and political development can match the pace of our technological development. If humans are no longer needed, then the value generated by their robotic counterparts must be distributed in new ways. For starters, is it time to end the 40 hour work week? Will we need regulation to restructure large companies? Can capitalism evolve to provide in the brave new world?

Lizard ID -  Central Florida:

Hey Pax could you possibly tell me what this little guy is exactly? He isn’t like most of the geckos we see around here. I live in central Florida and he was laying mostly still on the ground in one of the halls of my dorm. Unfortunately I don’t think they are in the best of health. Theres a second picture that I’ll submit separately of the head/eyes for a better look

Paxon:

There are a few species of gecko that have been introduced from other parts of the world into Florida. This looks to me like the Indo-Pacific Gecko (Hemidactylus frenatus), which is originally from SE Asia. Some pics you will look at will show them with smooth skin, and some with small spiky bumps. They are able (as are many geckos) of changing both the coloring/patterning and texture of their skin.

They surround my house. Hope they eat the indigenous green anole lizards like the brown anoles.

Microbeads a major problem in L.A. River

Scientist Marcus Eriksen stood ankle deep in the murky Los Angeles River on Friday and dipped a net into the water, looking for a problem. Eriksen was searching for “microbeads,” bits of plastic no bigger than salt grains that absorb toxins such as motor oil and insecticides as they tumble downstream and into the Pacific Ocean.
The tiny polyethylene and polypropylene beads are an emerging concern among scientists and environmentalists. The beads come mostly from personal care products such as facial exfoliants and body washes. They are not biodegradable, however, and because they are not removed easily by wastewater treatment plants, they flow out to sea and enter the food chain.
"Microplastic is now a ubiquitous contaminant in the Pacific Ocean — and seas around the world," said Eriksen, a scientist with the 5 Gyres Institute, a nonprofit dedicated to researching plastics in the world’s waterways. "We believe that 80% of it comes from coastal watersheds like Los Angeles."
Eriksen is just starting to test the Los Angeles River to determine if it holds microbeads, and if so, their source. On Friday, he found what he was looking for in about 10 minutes. Near the confluence of the river and Arroyo Seco, about three miles north of downtown, Eriksen found a handful of algae and wriggling leeches speckled with tiny filaments, shards and beads that could have come from myriad sources: laundry wastewater, degraded plastic bags, stir sticks, personal care products.
"The scary thing is that the beads sponge up toxins, then get consumed by organisms from shellfish to crabs to fish" later eaten by humans, he said.
Scientists are only beginning to understand the hazards posed by microplastic pollution in the world’s oceans and inland waterways. In 2012, Eriksen and a team of researchers discovered large amounts of microbeads and other microplastic pollution in the Great Lakes. Those findings prompted a coalition of mayors of Great Lakes cities to ask the U.S. Environmental Protection Agency to determine the possible health risks to lake ecosystems and humans.
A year later, 5 Gyres launched a campaign asking the manufacturers of personal care products to remove plastic microbeads and replace them with nonplastic alternatives such as crushed walnut husks and apricot kernels that will degrade naturally. Several companies have agreed to phase microbeads out of their product lines.
In a statement, the Johnson &amp; Johnson Family of Consumer Companies, for example, said it has “stopped developing new products containing polyethylene microbeads.” The company expects by 2015 to have replaced microbeads with alternatives in half the products that currently use them.

Hardy Bananas for the Midwest - by Denise Schreiber
In Pittsburgh, right up until the hard frost, we had bananas growing here. Yes you heard me right, bananas with those big leaves and tropical look. And they will return again next spring.
This particular banana is called hardy Japanese fiber banana (Musa basjoo). It is native to the Ryukyu Islands of Japan, and it can be grown in the ground in most parts of the Midwest.  As you dream of exciting new plants to add to next year’s garden, consider buying Musa basjoo. It is a little like adding a bit of Hawaii to your own Zone 5 or 6 backyard …

WHAT

It’s no lie =P I have heard many sources succeed with growing them in such cold zones, though I am sad to say I haven’t gotten a chance to proove it in my own gardens (yet… &gt;.&gt; )
It’s kind of hard to design a regular garden with a tropical like a banana though lol.
