Hubble astronomers assemble Wide View of the Evolving Universe

apparent size comparison of Legacy Field mosaic with full Moon
This graphic compares the dimensions of the Hubble Legacy Field on the sky with the angular size of the Moon. The Hubble Legacy Field is one of the widest views ever taken of the universe with Hubble. The new portrait, a mosaic of nearly 7,500 exposures, covers almost the width of the full Moon. The Moon and the Legacy Field each subtend about an angle of one-half a degree on the sky (or half the width of your forefinger held at arm’s length).

Synthetic Biology used to Target Cancer Cells while Sparing Healthy Tissue

(Top) some types of cancers are caused by mutated or overexpressed cell surface proteins that signal to the nucleus (green pathway) to drive uncontrolled growth and survival. (Bottom) Using an approach called RASER, the cancer-causing signals are redirected away from cell growth and survival and toward programmed cell death (orange pathway).

Synthetic proteins engineered to recognize overly active biological pathways can kill cancer cells while sparing their healthy peers, according to a study by researchers at the Stanford University School of Medicine...

Walnuts may help Lower Blood Pressure for those at risk of Heart Disease

When combined with a diet low in saturated fats, eating walnuts may help lower blood pressure in people at risk for cardiovascular disease, according to a new Penn State study.

In a randomized, controlled trial, researchers examined the effects of replacing some of the saturated fats in participants’ diets with walnuts. They found that when participants ate whole walnuts daily in combination with lower overall amounts of saturated fat, they had lower central blood pressure.

According to the researchers, central pressure is the pressure that is exer...

Storing Info in Molecules, for Millions of Years

As the data boom continues to boom, more and more information gets filed in less and less space. Even the cloud will eventually run out of space, can’t thwart all hackers, and gobbles up energy. Now, a new way to store information could stably house data for millions of years, lives outside the hackable internet, and, once written, uses no energy. All you need is a chemist, some cheap molecules, and your precious information.

“Think storing the contents of the New York Public Library with a teaspoon of protein,” says Brian Cafferty, first author on the paper that describes the new technique and a postdoctoral scholar in the lab of George Whitesides, the Woodford L...
