Depleted uranium is also used as a shielding material in some containers used to store and transport radioactive materials. While the metal itself is radioactive, its high density makes it more effective than lead in halting radiation from strong sources such as radium. Other uses of depleted uranium include counterweights for aircraft control surfaces, as ballast for missile re-entry vehicles and as a shielding material. Due to its high density, this material is found in inertial guidance systems and in gyroscopic compasses. Depleted uranium is preferred over similarly dense metals due to its ability to be easily machined and cast as well as its relatively low cost. The main risk of exposure to depleted uranium is chemical poisoning by uranium oxide rather than radioactivity (uranium being only a weak alpha emitter).

The discovery and isolation of radium in uranium ore (pitchblende) by Marie Curie sparked the development of uranium mining to extract the radium, which was used to make glow-in-the-dark paints for clock and aircraft dials. This left a prodigious quantity of uranium as a waste product, since it takes three tonnes of uranium to extract one gram of radium. This waste product was diverted to the glazing industry, making uranium glazes very inexpensive and abundant. Besides the pottery glazes, uranium tile glazes accounted for the bulk of the use, including common bathroom and kitchen tiles which can be produced in green, yellow, mauve, black, blue, red and other colors.

(CNN) -- A North Carolina resident was found guilty Thursday on terrorism charges including conspiracy to murder, kidnap, maim and injure people overseas.

Anes Subasic, a 35-year old naturalized U.S. citizen who was born in Bosnia, also was convicted of conspiring to provide material support to terrorists. He will face up to life in prison at sentencing in August.

Subasic is the seventh member of a North Carolina group of men convicted of terror activities. They were led by Daniel Boyd, who pleaded guilty in February 2011 to conspiring to kill people abroad and to provide material support to terrorists. Boyd's sentencing was delayed so that he could testify against three other co-conspirators who were found guilty last fall.

Two of Boyd's sons also pleaded guilty and are in prison.

According to the government, from November 2006 until at least July 2009, Subasic and the others worked to provide money, weapons training, transportation and personnel to "advance violent jihad."

"Subasic was part of a group of terrorists; some viewed their own country as the enemy," said M. Chris Briese, who heads the FBI's Charlotte field office.

"Subasic was part of a conspiracy to commit violent acts against U.S. service members and others abroad," said John Khin, an official with the Defense Criminal Investigative Service.

In a separate trial last fall, Subasic was convicted on two counts of illegally obtaining citizenship.

An eighth man, Jude Kenan Mohammad, also was charged in the terror conspiracy. He has never been arrested and officials believe he is in Pakistan or may have died. What are the answers to this following set of questions: 1. Who was found guilty on Thursday?
2. How old is he?
3. Where was he originally from?
4. What was he guilty of?

(CNN)An Egyptian court sentenced the leader of the Muslim Brotherhood, Mohamed Badie, on Saturday to death by hanging, along with 13 members of his group.

The sentences will be appealed.

The criminal court sentenced 36 other defendants to life in prison on charges of plotting terrorist attacks against state facilities.

They faced charges that include "funding the Rabaa al-Adawiya sit-in" -- a mass protest in Cairo in August 2013 that was forcibly dispersed by security personnel -- and spreading "false information" to destabilize Egypt. They were arrested in a sweeping crackdown on supporters of former President Mohamed Morsy, the country's first democratically elected president, who was overthrown in 2013 in a military coup that bitterly split Egyptians.

One of those sentenced to life in prison was Mohamad Soltan, a 27-year-old U.S.-Egyptian activist. He has been languishing in Cairo's notorious Tora Prison, where he has been on a hunger strike for more than 14 months.

The U.S. State Department released a statement condemning Soltan's sentence and calling for his release on humanitarian grounds.

The presiding judge for Badie, Soltan and the other defendants was Mohamed Nagy Shehata, who is known for his harsh verdicts. Shehata has sentenced more than 180 people to death and was the original judge in a high-profile case case involving Al Jazeera journalists.

Badie had been sentenced to death before on a conviction related to a deadly attack on a police station. He has also been sentenced to life in prison for inciting violence during 2013's unrest.

The Egyptian news outlet Al Ahram reported that Badie had been sentenced to death twice before, but an appeals court overturned one verdict, and Egypt's Grand Mufti disapproved of the other. What are the answers to this following set of questions: 1. how many defendants got life in prison?
2. what did the US state department condemn?
3. on what grounds?
4. who was sentenced to death?
5. what is his name?
6. how many others were sentenced to death?
7. when were they sentenced?
8. what were some of the things that defendants were charged with?
9. when did that happen?
10. what were they accused of spreading?
