What got you interested in your major?

I took a general education course, SAS 20 - Genetics and Society, in my freshman year and that triggered my interest in the sciences. From there on I took more science classes and developed a curiosity for molecular biology and how the human body functions.

What do you teach? Why did you decide to teach it?

Well, I teach physics, and I actually got interested about the seventh grade. There was a brief stint when I wanted to be a forest ranger! The way I sort of got started in physics was because my aunt gave me a Christmas gift when I was in the seventh grade. It was a subscription to a book-of-the month club for children, and one of the first books I got was on the Manhattan Project, and they were describing nuclei and stuff and how big things were, and they said that if you take the nucleus of a hydrogen atom, which is a proton and you laid a quadrillion of them end to end they'd take up about a quarter of your fingernail and I said, 'Wow! How do you measure something so small?' Obviously, you don't pull out a meter stick, so how did they determine that size? The seventh grade science teacher I had basically was clueless, but … basically when I got to college, I learned about the Rutherford experiments and how all these sizes were originally determined using the scattering of particles. So, it was just that quest, how do you measure something so small that got me interested in physics, and sort of held onto me.

Ozone kills

A report released byNational Academies' National Research Council has found significant evidence that ozone leads to premature death,especially in the elderly.Children also can be negatively affected by the gas.Ozone(O3) is produced at the earth's surface when light reacts with other air pollutants such as nitrogen oxide and hydrocarbons.

Ozone oxidizes lung tissue,decreasing lung capacity,causing respiratory inflammation and worsening heart disease.It can worsen lung diseases such as asthma.

The sound of metal clinking carries through the hallway as two students help bring out long pieces of steel through Bainer Hall. The students place the structures inside of a perimeter marked by white tape.

The UC Davis Steel Bridge Team, better known as team "Chrome Ollie," is setting up and about to practice assembling their steel bridge for the upcoming Mid-Pacific Regional Competition on Apr. 26 at the Mondavi Center's Parking Structure from 7:30 a.m. to 5:30.

The steel bridge contest brings out other teams in the region to compete against each other in the design and formation of scale-size bridge structures. While the competition can be stressful, it can also be fun.

A small plane whizzes by, hovering low to the ground. One might think that the pilot is trying to have some fun, but in reality the airplane is ejecting certain chemicals to try to eliminate a pest.

This pest is the light brown apple moth, epiphyas postvittana, a non-native insect to North America. According to the California Department of Food and Agriculture. It is an invasive pest of California's environment, natural habitat and agriculture. Because the Department of Food and Agriculture is fearful that the moth is capable of devastating California's agriculture, an aerial spraying program has been set up to eradicate the moth.

What influenced you to choose your major?

I was originally a genetics major, but I realized if I went on that path, I would probably end up going into research. I'm interested more in the human interaction aspects of genetics, and I want to go into genetic counseling, so I can do that with human development instead.

Computers might run on infrared light

Computer engineers at the University of Utah have begun to build computers that can harness infrared light, the only part of the electromagnetic spectrum that has not yet been utilized for communication. The engineers expect that in another 10 years they will have built ultra-fast computers that don't run on electricity.

Where electricity is conducted through metal wires, computer circuits built on light rely on fiber optic cables and devices called waveguides to split the light into different colors or "channels" of information.

You hit your snooze button for the third time and suddenly realize you have 10 minutes before your next class starts. You clamber out of bed, jumping around and stabbing a leg through each pant leg while attempting to read the blurry lines of numbers on the bus schedule. As you try to figure out which bus you could catch, you take a chance and hope the bus that arrives in less than a minute will be late.

This game of chance could soon become a distant memory, as Global Positioning System mass transit tracking systems are beginning to be launched through the country's university campuses.

Leading physicists say "God particle" soon to be found

Forty years ago, British physicist Peter Higgs argued that there was a force that gave mass to the universe, enabling life to exist. From this invisible force, named the Higgs field, comes a particle called the Higgs boson. Now, as a particle accelerator in Geneva is nearly ready to begin functioning in May, Higgs says he is 90 percent sure that the particle will be found.

How did you choose your major?

I wanted to be able to apply math and science, and I know that you had many more options with an engineering degree than you did with a math or physics degree.

Employment opportunities are shrinking, food and gas prices are rising, houses are being foreclosed and banks have stopped their liberal lending policies. Does this mean our economy is in a recession, that daunting word that strikes fear in the hearts of the government and consumers alike? Not necessarily. Does the Federal Reserve System, the central bank of the United States, have a plan to help stimulate the economy beyond a temporary fix? Only time will tell, say economists.

First of all, it must be noted that recession has a complicated definition, and can only be officially announced by the National Bureau of Economic Research, said Kevin Salyer, professor of economics at UC Davis, in an e-mail interview.

"A rule of thumb definition is two quarters (6 months) of negative GDP growth," Salyer said. "We are not technically in a recession yet (but some economists believe we are … and today's jobs data suggests that they might be correct)."
