"This work is one of the first to explore how networking policies affect how the network is used," Heidemann said.

There are 4 billion IPv4 internet addresses. Heidemann and his team pinged about 3.7 million address blocks (representing about 950 million addresses) every 11 minutes over the span of two months, looking for daily patterns.

"This data helps us establish a baseline for the Internet — to understand how it functions, so that we have a better idea of how resilient it is as a whole, and can spot problems quicker," Heidemann said.

Genetic modification can produce biofortified corn rich in provitamin A

Genetic modification can produce biofortified corn rich in provitamin A

A set of genes that can be used to naturally boost the provitamin A content of corn kernels, a finding that could help combat vitamin A deficiency in developing countries.

Purdue professor of agronomy Torbert Rocheford and fellow researchers found gene variations that can be selected to change nutritionally poor white corn into biofortified orange corn with high levels of provitamin A carotenoids - substances that the human body can convert into vitamin A. Vitamin A plays key roles in eye health and the immune system, as well as in the synthesis of certain hormones.

Satellites sees a question mark in Tropical Storm Ana

Satellites sees a question mark in Tropical Storm Ana

NOAA's GOES-West satellite captured an image of Tropical Storm Ana that showed the outer clouds were already reaching the big island by 11 a.m. EDT and the storm resembled a giant question mark.

Tropical Storm Ana was nearing hurricane strength mid-day on Oct. 17 and the Central Pacific Hurricane Center (CPHC) expects the storm to become a hurricane before reaching the big island of Hawaii.

Mediterranean, semi-arid ecosystems prove resistant to climate change

Climate change predictions for the Middle East, like other arid regions of the world, are alarming. In an area known for its water scarcity, rainfall is expected to decrease even further in the near future, spelling disaster for the functioning of unique ecosystems — hotspots of biodiversity and rich genetic fodder for essential crops.

Asbestos likely more widespread than previously thought

Boulder, CO, USA — Naturally occurring asbestos minerals may be more widespread than previously thought, with newly discovered sources now identified within the Las Vegas metropolitan area. The asbestos-rich areas are in locations not previously considered to be at risk, according to new report that will be presented at the Annual Meeting of the Geological Society of America (GSA) in Vancouver, Canada, on Sunday, 20 October.

Scientists create possible precursor to life

How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If we can create artificial living systems, we may not only understand the origin of life - we can also revolutionize the future of technology.
