Jump for your life: Bipedal rodents survive in the desert with a hop, a skip and a jump
[unable to retrieve full-text content]Researchers have found that bipedal desert rodents manage to compete with their quadrupedal counterparts by using a diverse set of jumps, hops and skips. A new study suggests that it is this unpredictable movement that allows the bipedal rodents to coexist in Old World deserts with quadrupedal rodents.

Hurricane Erick gathers off coast of Mexico
Erick strengthened to a hurricane off of southern Mexico Saturday, threatening to dump heavy rain as it skirts the country's Pacific coast.
The presence of the Category 1 hurricane forced the closure of the seaport of Manzanillo, Mexico's biggest container port.
The U.S. National Hurricane Center in Miami said Erick became a hurricane as its maximum sustained winds grew to around 110 kph.
The hurricane was centred about 145 kilometres south of Manzanillo and was moving northwest at 15 kph, on a track roughly parallel to the coast for the states of Guerrero, Colima and Jalisco.
A hurricane watch was declared for Punta San Telmo to Cabo Corrientes, and a tropical storm warning was in effect from the resort of Zihuatanejo westward to Cabo Corrientes.
Gabriel Rivas, a meteorologist at the Manzanillo Port Authority, said the port was closed late Friday as a precaution, but no rain or high winds had yet been reported in the area.
In neighbouring Jalisco state, civil defence officer Leonel Hernandez said authorities in coastal communities were meeting to plan preparations for the hurricane, but that skies in the Jalisco coastal community of Cihuatlan were still clear.
Forecasters predict a northwest to west-northwest track over the next few days but say the storm should remain offshore. Rain accumulations from 76 to 127 millimetres are expected. Forecasters warn of flash floods.

As Fortnight for Freedom concludes, Cardinal Wuerl decries threats to Church's freedom, defends college chaplain
CWN - July 05, 2013
Evoking the persecution of Catholics in colonial Maryland, Cardinal Donald Wuerl concluded the US bishops? second Fortnight for Freedom by decrying threats to the Church?s liberty and defending a priest who faced opposition at George Washington University after he called upon homosexual students to lead chaste lives.
In 1634, the Catholic settlers of Maryland ?constructed what would become known as the birthplace of religious freedom in America,? Cardinal Wuerl preached at a Mass at the Basilica of the National Shrine of the Immaculate Conception in Washington. ?Unfortunately, in 1704, when those who did not share this foresight and Catholic perspective gained political control, they revoked the freedom of religion in the colony. They found it more convenient to silence the Church ? even with force ? than to live in peace with her and her Gospel message.?
?Closer to our day, we see another tactic,? he continued. ?The Church is denounced as prejudiced, narrow-minded or even un-American simply because her teaching respects human life, upholds marriage and calls for health care for the most needy in our country. In March, just across town, we witnessed an example of the new intolerance, the new form of locking doors. At George Washington University an effort was made to silence the Catholic chaplain and to ?lockout? his ministry to Catholic students and faculty just because he taught those who freely came to Mass what Jesus said about marriage.?
Recalling Pope Benedict?s concern about radical secularism in the United States, Cardinal Wuerl added that
The Holy Father?s answer to this ?radical secularism? and ?denial of rights? is, as he explained, ?an engaged, articulate and well-formed Catholic laity endowed with a strong critical sense vis-?-vis the dominant culture and with the courage to counter a reductive secularism.? And here you are!Your faith is a remedy for what ails our society. The mission of all of us, but particularly of the laity is to engage the culture with the Good News that only comes from Jesus Christ.

PRINCETON, N.J. (AP) ? With a 3-D printer, a petri dish and some cells from a cow, Princeton University researchers are growing synthetic ears that can receive ? and transmit ? sound.
The scientists send bovine cells mixed in a liquid gel through the printer, followed by tiny particles of silver. The printer is programmed to shape the material into a "bionic ear," and forms the silver particles into a coiled antenna. Like any antenna, this one can pick up radio signals that the ear will interpret as sound.
The 3-D ear is not designed to replace a human one, though; the research is meant to explore a new method of combining electronics with biological material.
"What we really did here was actually more of a proof of concept of the capabilities of 3-D printing," said Michael McAlpine, the professor who led the project. "Because most people use 3-D printing to print passive objects ? things like figurines and jewelry."
After it's printed, the 3-D ear is soft and translucent. It is cultivated for 10 weeks, letting the cells multiply, creating a flesh color and forming hardened tissue around the antenna.
Manu Mannoor, a graduate student who worked with McAlpine on the project, held up a petri dish in a lab at Princeton last week to show how the process works. The dish was filled with liquid and a partly cultivated ear, and Mannoor said the cells were secreting a matrix, the space between cells that exists in organisms.
"They make their own living space," Mannoor said.
McAlpine and his team demonstrated the antenna's ability to pick up radio signals by attaching electrodes onto the backs of the ears in the printing process. When they broadcast a recording of Beethoven's "Fur Elise" to a pair of fully cultivated ears, the electrodes transmitted the signal along wires to a set of speakers, and the music flowed out clear and without interference.
Although the new research is just one iteration in the field of cybernetics ? an area that looks at combining biology with technology ? McAlpine said the research could lead to synthetic replacements for actual human functions, and to a sort of electronic sixth sense.
"As the world becomes a more digital and electronic place, I think ultimately we're going to care less about our traditional five senses," he said. "And we're going to want these new senses to give us direct electronic communication with our cellphones and our laptop devices."

Sioux Tribes Plan Large-Scale Wind Energy Project
Eaton reports: "A group of Sioux tribes in South Dakota are hoping to pump some much-needed revenue into their economies with an ambitious wind project."

05 July 13
?
group of Sioux tribes in South Dakota are hoping to pump some much-needed revenue into their economies with an ambitious wind project, but some wind industry experts question whether the tribes understand the hurdles they face with such a large-scale development.
Leaders from six Sioux tribes announced plans at last month's Clinton Global Initiative to develop a renewable energy project that would generate 1 to 2 gigawatts of power annually. Funding for the up to $3 billion project would come from the sale of bonds by a new multi-tribal power authority as well as donations to a website.
"It gives Native tribes who aren't in populace areas and don't have casino revenue a chance to earn some real money that can then be used to reinvest into the community to diversify the economic base that exists," Clinton said at the event. The Sioux tribes are located in some of the poorest areas in the country.
But wind energy experts said the tribes face many obstacles in making the project a reality.
"When I see plans for a thousand megawatts, I have to give a chuckle," said Steve Wegman, an analyst for the South Dakota Renewable Energy Association, who noted that the project is similar to one proposed years ago. "The goal is good, but it's going to take them a long time to get there."
One of the biggest obstacles to the project is simply what to do with so much energy in a state that doesn't demand a lot.
Wind energy demand in South Dakota sits at less than 800 megawatts currently. Wegman said. Another 100 will be put on line in the next year.
"After that it's going to be slow going," he said.
Ron Rebenitsch, executive director of the South Dakota Wind Energy Association, said all wind developers face three challenges: finding a buyer for the energy, transmitting it and following the environmental and regulatory requirements.
Since South Dakota is a small state that doesn't require a lot of power, the multi-tribal power authority will need to look east to places such as Minneapolis and Chicago, Rebenitsch said. But then the challenge becomes getting it to those locations. New wind generation requires new lines, and a gigawatt or more would require several major lines, which cost about $1 million per mile and take up to a year and a half to build.
The tribes recognize that there isn't much demand locally, which is why they're hoping to sell it to cities such as Anaheim, Calif., or Oklahoma City and connect with a company that already has a transmission system in place, said Paul Valandra, an economic development adviser with the Rosebud Sioux Tribe.
He said building the wind energy project is in the national interest and is "a little bit of social justice" for the tribes, who have felt wronged by the U.S. government in the past.
"We're going slow, but we want to do a first-class job on this project," Valandra said.
One advantage the tribes could have over other entities is building the turbines on reservation land, which may not require gaining approval from individual landowners for the project, Rebenitsch said.
"The tribe have some very good areas...If they can do it all on tribal lands, they can probably move forward in that area," he said.
