(CNN) -- Cuba will pardon more than 2,900 prisoners, the government said Friday, though U.S. subcontractor Alan Gross is not among those who will be freed. The decision to release the prisoners follows "numerous requests" from their family members and religious institutions, and is a humanitarian gesture, said Cuban President Raul Castro. Among those who might be freed are prisoners over the age of 60, along with those who are sick, female or young with no previous criminal record. With some exceptions, prisoners convicted of spying, terrorism, murder and drug trafficking will not be released. Those who will be freed have already served a "important" part of their sentences and exhibited good behavior, according to an official statement published on the state-run website Cubadebate. The jailed American, Gross, will not be among those pardoned, the Cuban Interests Section in Washington said. Gross was jailed in December 2009, when he was working as a subcontractor on a U.S. Agency for International Development project aimed at spreading democracy. Castro has accused him of importing satellite equipment to connect dissidents to the Internet, and this year Cuba's highest court upheld the 15-year sentence imposed on Gross for committing crimes against the security of the state. He has maintained his innocence and said he was trying to help connect the Jewish community to the Internet. Castro, speaking to the National Assembly, said that 86 prisoners from 25 countries would be among those released in coming days. He cited the upcoming visit of Pope Benedict XVI as one of the motivations behind the move, which he said showed the "generosity and strength of the revolution." The pope has said he plans to visit Mexico and Cuba before Easter.

Question: "Of the 2,900 prisoners, who will not be released?"

Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "What does density tell?"

Answer: "How big things are"

Response: no

Right after the Pentagon was hit, NEADS learned of another possible hijacked aircraft. It was an aircraft that in fact had not been hijacked at all. After the second World Trade Center crash, Boston Center managers recognized that both aircraft were transcontinental 767 jetliners that had departed Logan Airport. Remembering the "we have some planes" remark, Boston Center guessed that Delta 1989 might also be hijacked. Boston Center called NEADS at 9:41 and identified Delta 1989, a 767 jet that had left Logan Airport for Las Vegas, as a possible hijack. NEADS warned the FAA's Cleveland Center to watch Delta 1989. The Command Center and FAA headquarters watched it too. During the course of the morning, there were multiple erroneous reports of hijacked aircraft. The report of American 11 heading south was the first; Delta 1989 was the second. NEADS never lost track of Delta 1989, and even ordered fighter aircraft from Ohio and Michigan to intercept it. The flight never turned off its transponder. NEADS soon learned that the aircraft was not hijacked, and tracked Delta 1989 as it reversed course over Toledo, headed east, and landed in Cleveland. But another aircraft was heading toward Washington, an aircraft about which NORAD had heard nothing: United 93. United Airlines Flight 93 FAA Awareness. At 9:27, after having been in the air for 45 minutes, United 93 acknowledged a transmission from the Cleveland Center controller. This was the last normal contact the FAA had with the flight. Less than a minute later, the Cleveland controller and the pilots of aircraft in the vicinity heard "a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin." The controller responded, seconds later: "Somebody call Cleveland?"This was followed by a second radio transmission, with sounds of screaming.

Question: "Which air traffic center communicated with United 93?"

Answer: "Logan Airport"

Response: no

Michigan will lose $2 million in federal funding and $600,000 in state funding to provide legal aid to the poor in 2003, according to Deierdre L. Weir, executive director of the Legal Aid and Defender Association, Inc., the state's largest provider of legal services to the poor. Current federal funds of nearly $10.7 million from the Legal Services Corporation (LSC) will drop to $8.7 million for next year, according to Weir. She said that the reductions reflect a decline in the number of persons in the state who are living in poverty, according to the U.S. Census Bureau's 2000 census. LSC uses census data to determine funding across the nation, and according to the census, the state's poverty population fell from an estimated 1.2 million in 1990 to an estimated 968,000 in 2000. The state's legal aid agencies are also bracing for yet another cut in 2003 of some $600,000 of state funding. A portion of filing fees paid by litigants in the state's circuit courts, and a portion of interest on lawyers trust accounts (IOLTA) are earmarked for Michigan legal aid programs. These funds are expected to drop from currently $7.5 million in 2002 to $6.9 million when the Michigan State Bar Foundation makes distributions next year. Most of the decrease is attributed to the past year's low interest rates. "The irony of these funding cuts is that while there may be fewer poor people in Michigan today, the demand for service will not change because the poverty population remains so large and the legal aid funding so little that local providers will never able to serve all who need our service," said Weir. "It's as if the poor will be victimized twice-once for being poor and again as victims of these funding cuts." The U.S. Census Bureau, in spite of its best efforts, cannot locate every poor person living in a census tract, therefore the poor are also undercounted, added Weir. The brunt of these cuts will be felt most in Wayne County where according to the census some 333,000 poor people live, the largest concentration of poverty in the state. LAD will lose more than $870,000 for legal aid in Wayne County, nearly half of the state's total loss, said Weir. While difficult to measure, the loss of funds will mean that several thousand of Michigan's poor in need of legal service will not receive it, or they will receive significantly limited service. Cutbacks will include service in such civil legal matters as landlord-tenant, bankruptcy, consumer, child custody, predatory lending, mortgage foreclosure, utility shutoffs, social security, wills, and probate. "Local providers will have to work harder and smarter and use more technology instead of staff to provide as much service as we can with fewer dollars," said Weir. "We will be providing more selfhelp training to clients enabling them to navigate the legal system on their own in routine matters, more assistance on the telephone, and less direct representation by attorneys in specific, high impact matters. Currently, Michigan has 13 legal aid agencies covering the state's 83 counties.
