Problem: Nathan Phillips, who will formally begin his freshman year at the University of San Diego(USD) on Aug. 31, will arrive on campus in an unusual and philanthropic manner.

Phillips is expected to arrive between 5 p.m. and 6 p.m. Thursday on his bicycle, having pedaled 1,450 miles from Astoria, Ore.

Phillips combined his desire to complete a long bike ride before entering college with his interest in helping the children of Uganda.

He is raising funds for Invisible Children, a San Diegobased organization seeking to end conflicts annoying northern Uganda, the Democratic Republic of Congo and the Central African Republic and stop the use of children as soldiers.

Phillips had raised $1,540 before embarking Aug.11 and hopes to reach $2,000.

Phillips, who is from Redmond, Washington, visited Uganda during high school and worked in an orphanage there. He was also inspired by a presentation by Invisible Children at his high school.

"I have been to Uganda and personally gotten to know some of the kids affected by the war," Phillips said in a statement released by the university."I would do anything to help these kids."

Phillips' new roommate, Kyle Sharp, has joined him for the last 600 miles of the trip. Students and other members of the USD community are expected to join him for the last 13 miles.

"Nathan's passionate commitment to improving the lives of children more than 8,000 miles away resonates with USD's mission to prepare future leaders to change the world for the better," Pamela Gray Payton, assistant vice president of public affairs at USD, said in a prepared statement."We are delighted to have Nathan as a member of our campus community."

Supporters from USD and Invisible Children will greet Phillips and his followers when they arrive in front of Founders Hall on campus. The public is invited as well.

Problem: (CNN) -- A man is accused of breaking into an Anchorage, Alaska, home over the weekend, sexually assaulting an elderly woman, killing her and her husband, and sexually assaulting the couple's 2-year-old great-granddaughter before fleeing the scene in his boxer shorts.

Jerry Andrew Active, 24, was arrested about a block from the home. He was charged with first and second degree murder, sexual assault and burglary, said Anchorage Police Sgt. Slawomir Markiewicz. Active is being held on $1.5 million bond.

Markiewicz said police were called to the home shortly before 8 p.m. Saturday. When they arrived, they found Touch Chea, 71, and his wife, Sorn Sreap, 73, dead, apparently due to blunt force trauma to the head and face, Markiewicz said. Autopsies are pending.

Police also found in the home the couple's great-granddaughter, who was sexually assaulted. Sreap had also been sexually assaulted, police said.

"I've been in the homicide unit for the last eight years and it's certainly one of the worst homicides we've seen in our town, in our city," Markiewicz told CNN's Brooke Baldwin Monday night.

The sergeant said the 2-year-old's father told police that he and his wife, who is pregnant, lived in the home with their children -- ages 4 and 2 -- along with Chea, Sreap and another relative.

They took their 4-year-old to the movies on Saturday, leaving their youngest in the care of the child's great-grandparents.

When they returned, the front door was locked and there was a chain on from the inside, blocking their way.

Problem: Simply by analyzing a drop of blood, a doctor will be able to diagnose a birth defect or even cancer when it is in the early stage; using new technology, a material lighter but much stronger than steel can be produced.

These may sound like dreams at present. But the dreams may soon come true as research findings in laboratories are being turned into products more rapidly in the new century, according to experts participating in the fourth Asia-Pacific Economic Cooperation (APEC) Technomart, a technology exhibition and trade fair in Suzhou.

"Most people think nano-technology is too far-fetched to be real. But in fact nano-technology has been applied in a wide range of fields, such as medicine. It is coming into our daily life," said Cheng Jiachong from a Hong Kong-based nano-technology firm.

Nano-technology based on the nanometer, the unit of which is a billionth of a meter, enables scientists to have new concepts of disease diagnosis and treatment on a molecular and atomic scale, Cheng said.

By using nanometer particles, a doctor can separate the fetus cells from the blood of a pregnant woman to see if the development of the fetus is normal. This method is also being used in the early diagnosis of cancer and heart disease, he said.

One of the most significant impacts of nano-technology is at the bio-inorganic materials interface, according to Greg Tegart, executive advisor of the APEC Center for Technology Foresight.

"By combining enzymes and silicon chips we can produce biosensors. These could be implanted in humans or animals to monitor health and to deliver corrective doses of drugs," he told the participants a technology forum during the exhibition.

"Nano-technology could affect the production of nearly every man-made object, from automobiles, tires and computer circuits , to advanced medicines and tissue replacement, and lead to the invention of objects yet to be imagined," said David Minns, a special advisor to the National Research Council of Canada.

It has been shown that carbon nano-tubes are ten times as strong as steel, with one sixth of the weight, and nano-scale systems have the potential to make supersonic transport cost- effective and to increase computer efficiency by millions of times, he said.

The experts agreed that the APEC technology exhibition and trade fair provided many chances for exchanges of innovative ideas and products.
