Computer scientists develop tool to make the Internet of Things safer

Computer scientists have developed a tool that allows hardware designers and system builders to test security -- a first for the field. There is a big push to create the so-called Internet of Things, where all devices are connected and communicate with one another. As a result, embedded systems -- small computer systems built around microcontrollers -- are becoming more common. But they remain vulnerable to security breaches. Some examples of devices that may be hackable: medical devices, cars, cell phones and smart grid technology.

Common house ants form super colonies, prosper in Urban Settings

One of the most common house ant species might have been built for living in some of the smallest spaces in a forest, but the ants have found ways to take advantage of the comforts of city living.

Grzegorz Buczkowski, a Purdue University research assistant professor of entomology, found that odorous house ant colonies become larger and more complex as they move from forest to city and act somewhat like an invasive species. The ants live about 50 to a colony with one queen in forest settings but explode into supercolonies with more than 6 million workers and 50,000 queens in urban areas.

Iran to put 3 satellites into orbit this year

An Iranian aerospace official says the country plans to launch three indigenously designed and manufactured satellites into orbit during the current Iranian calendar year (started March 21, 2014).

Deputy Head of Iran Space Agency (ISA) Hamid Fazeli said on Saturday that Sharif Sat, Tadbir (Prudence) and Fajr (Dawn) satellites will be lifted into space before the end of the year.

He went on to say that the satellites are ready to be launched into orbit and that they will be lifted into space in due time.

Iran displays indigenous version of US RQ-170 drone

Iran has unveiled an indigenous version of a sophisticated American reconnaissance drone that it brought down and seized in 2011 while it was conducting a surveillance operation over Iranian airspace.
The stealth drone was showcased in an exhibition at the Islamic Revolution Guards Corps (IRGC) Aerospace Force Central Command that was attended by the Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei.
Other domestically-manufactured Unmanned Aerial Vehicles (UAV), including Shahed 129 and 125, were also on display during the exhibition.

Scientists Reveal That Jupiter's Moon Ganymede May Support Life

Scientists have revealed that Jupiter's moon Ganymede may possess ice and liquid oceans stacked up in several layers - raising the chances that this distant icy world harbored life.

As club sandwiches go, this undoubtedly is the biggest one in the solar system.

Scientists said on Friday that Jupiter's moon Ganymede may possess ice and liquid oceans stacked up in several layers much like the popular multilayered sandwich. They added that this arrangement may raise the chances that this distant icy world harbors life.
