Ariana Christine

Our daughter turns 8 weeks old today. With all the negative things I see around the world today, it is a wonderful feeling to be able to look at her and think about all the good things in life. I am probably biased, but I think she's a pretty cute baby.

She likes to look at the ceiling fans. She likes to look at the wooden slats on our headboard. She sometimes sticks her tounge out a little when she's concentrating (just like her Dad). She laughs in her sleep, and sometimes wakes herself up doing so.

Family is the most amazing, uplifting, and supportive thing in the world if we allow it to be. Families are like small, independent support systems. They are the building block of a good society when they are whole and functional. Prophets and Apostles of the Lord Jesus Christ have stated unequivocally that, “The family is ordained of God. Marriage between man and woman is essential to His eternal plan. Children are entitled to birth within the bonds of matrimony, and to be reared by a father and a mother who honor marital vows with complete fidelity. Happiness in family life is most likely to be achieved when founded upon the teachings of the Lord Jesus Christ. Successful marriages and families are established and maintained on principles of faith, prayer, repentance, forgiveness, respect, love, compassion, work, and wholesome recreational activities. By divine design, fathers are to preside over their families in love and righteousness and are responsible to provide the necessities of life and protection for their families. Mothers are primarily responsible for the nurture of their children. In these sacred responsibilities, fathers and mothers are obligated to help one another as equal partners. Disability, death, or other circumstances may necessitate individual adaptation. Extended families should lend support when needed.”

Backpack harnesses pedestrian power

(CNN) -- Mobile phone users or iPod addicts could soon be spared the hassle of having to recharge batteries by a backpack that converts energy from walking into electricity.

By harnessing the backpack's up-and-down motion, researchers say the device is capable of generating more than seven watts -- more than enough energy to power several portable devices at once.

Scientists at the University of Pennsylvania devised the technology after being asked by the U.S. military to come up with a light rechargeable battery that could be used by troops one the battlefield.

Soldiers currently carry up to 20 lbs in spare batteries to power high-tech equipment such as global positioning systems and night vision goggles.

But Professor Larry Rome, who led the research, said the technology could benefit anyone who needed "power on the go."
Details of the "Suspended-load Backpack" are revealed in the latest edition of the journal Science.

"As efficient as batteries have gotten, they still tend to be heavy. Field researchers, for example, have to carry many replacement batteries to power their equipment, which take up a lot of weight and space in the pack," said Rome.

"The Suspended-load Backpack could help anyone with a need for power on the go, including researchers, soldiers, disaster relief-workers or someone just looking to keep a mobile phone charged during a long trek."

The backpack consists of bag suspended from a fixed frame by vertical springs. As the bag is moved up and down by the wearer's walking motion it creates enough mechanical energy to drive a generator mounted on the frame.

Portable devices such as mobile phones typically require less than one watt, but by carrying loads of 40-80 lbs, the research team were able to generate more than seven times as much power.

Instead of carrying extra batteries, Rome said wearers could compensate for carrying a heavier load by packing high-energy snacks.

"Metabolically speaking, we've found this to be much cheaper than we anticipated. The energy you exert could be offset by carrying an extra snack, which is nothing compared to weight of extra batteries," said Rome said.

"Pound for pound, food contains about 100-fold more energy than batteries."
